A Few Words of Thanks

Thank you for purchasing the Pro 3, our latest effort to make the world's greatest monosynth. That's a bold statement, but it's true. Our biggest pleasure here at Sequential is trying to outdo ourselves with each new instrument.

In many ways the Pro 3 is the evolution of a concept that started with the classic Sequential Circuits Pro-One — pack as much power as possible into a compact footprint and make it sound awesome. In this case, that power comes in threes: three oscillators, three filters, three LFOs, plus our most powerful sequencer yet. And there’s plenty of modulation; over thirty-two slots worth, in fact.

Our formula seems to have worked. The Pro 3 doesn't just sound good, it sounds amazing. We love this synth and hope you will, too.

So stop reading and starting playing!

Cheers,

DAVE SMITH

Chapter 1: Getting Started

The Pro 3 is a hybrid synthesizer in the best sense of the word. It combines the warmth and punch of two analog, voltage-controlled oscillators and three types of classic analog filters with the versatility of a third, digital wavetable oscillator and an array of digital effects.

This blend of technologies gives you an instrument that's sonically satisfying to play, but also has power and flexibility rivaling modular systems through its extensive modulation capabilities and four control voltage ins and outs.

This chapter of your user's guide provides an overview of essential tasks such as how to make basic audio connections and how to edit and save sounds. Later chapters explain each of the parameters of the Pro 3, as well as how to program sounds and how to use the GLOBAL menu to manage its overall behavior.

We've designed the Pro 3 to be as easy to use as possible. Its essential controls are within easy reach on its front panel, so don't hesitate to dive in and start turning knobs and pressing buttons. Then, when you're ready, dig into this user's guide to explore the deeper parts of the synth.

Rear Panel Connections

The rear panel of the Pro 3 has connectors for power, USB, MIDI, audio, and pedals.

1. Power On/Off—This rocker switch controls power on and off to the Pro 3.

2. AC Power Connector—Accepts a standard, grounded IEC power cord. Operates over a range of 100 to 240 volts, 50 to 60Hz , and 15W.

3. Electric Shock Hazard Warning—These symbols warn that you risk electrical shock if you open the Pro 3 enclosure. Please do not open.

4. USB—For bidirectional MIDI communication with a computer. The Pro 3 is a Class Compliant USB device and does not require additional drivers when used with Mac OS or Windows. See “Using USB” on page 4 for more information.

5. MIDI In, Out 1, Thru, Out 2—Standard 5-pin MIDI DIN connectors for communicating with MIDI-equipped devices.

6. Footswitch—Accepts a momentary, normally open or normally closed footswitch to control sustain or to latch the Arpeggiator on when keys are held. Alternatively, an audio signal connected to the AUDIO IN jack can be used to either control Sequencer/Arpeggiator playback, or to gate the filter and amplifier envelopes while notes are held. Audio signals used to drive the Arpeggiator/Sequencer should not exceed 5 volts peak-to-peak.

PRO 3 FT/SATCH PEDAL 1 2 3 4 1 2 3 4 GATE OUT AUDIO IN AUDIO OUT LEFT 6789101112

1. Pedal—Accepts a standard expression pedal that has a variable resistor on a TRS (tip-ring-sleeve) 14 inch phone plug. Once connected, you can use the modulation matrix to route the pedal to control a variety of things such as volume or filter cutoff frequency to add expressiveness to live performance.

2. Control Voltage Ins 1-4—Standard 3.5 mm connectors. These jacks accept a +/-5V signal for interfacing with modular synthesizers. They can be configured for 1-volt-per-octave operation for gear that recognize that standard.

3. Control Voltage Outs 1-4—Standard 3.5 mm connectors. These jacks output a +/-5V signal for interfacing with modular synthesizers. They can be configured for 1-volt-per-octave operation for gear that recognize that standard.

4. Gate Out—Standard 3.5 mm connector. This jack outputs a 10-volt on/off signal to switch a note on/off in external Sequencers and other devices that support this type of connectivity.

5. Audio In—Unbalanced, 14 inch audio input. The Pro 3 accepts external audio signals for processing through this connector. Input level can be adjusted using the EXT AUDIO knob in the Mixer section.

6. Audio Outputs—Unbalanced, 14 inch audio outputs. The Pro 3 sounds great in stereo, but can be switched to mono if needed. See “Global Settings” on page 96.

7. Headphones (on front) — 14 inch stereo headphone jack. Headphone volume is controlled by the MASTER VOLUME knob on the front panel.

Using USB

The Pro 3's USB 2.0 port enables bidirectional MIDI communication with a computer. A MIDI interface and MIDI cables are not necessary, just a USB cable. The Pro 3 is a Class Compliant USB device. That means it does not require any additional drivers to be installed to communicate with a Mac or Windows computer. The Pro 3 transmits and receives MIDI data via USB, but does not transmit audio.

MIDI In and USB should not be used at the same time, as overlapping

messages from different sources may cause the Pro 3 to respond unpredictably. MIDI Out and USB can be used at the same time and transmit the same data.

Under Mac OS, “Pro 3” will appear as a MIDI port when connected via USB and can be configured using the Mac’s Audio MIDI Setup utility (typically found in Applications/Utilities).

Under Windows, the first time the Pro 3 is connected via USB, the “Found new hardware” alert appears and it is automatically installed as “Pro 3.”

In Windows, if you unplug the USB cable and plug it back in while a program has the Pro 3 port open, you may have to resync. That usually means going to the Pro 3 Keyboard Properties — in the Windows Device Manager under “Sound, video, and game controllers” — and clicking OK. If Pro 3 is no longer listed in the Device Manager, turn off the Pro 3 then turn it back on again while it is connected via USB. It should be detected on power up.

Setting Up the Pro 3

Here's how to get your Pro 3 up and running:

Getting Started:

1. Plug the power cable into the AC power connector on the back panel of the Pro 3.
2. If you have an expression pedal, connect it to the PEDAL jack on the back of the Pro 3. If you have a sustain pedal, connect it to the FOOT-SWITCH jack.
3. Turn on the Pro 3.
4. Connect the LEFT and RIGHT audio outputs on the back of the Pro 3 to your amp/mixer/powered speakers using unbalanced, 14 inch audio cables. These are the main stereo outputs for the synth.
5. Turn up the volume on your amp/mixer/powered speakers.
6. Turn up the volume on the Pro 3.
7. Use the BANK and PROGRAM knobs to scroll through the factory sounds. You can also use Soft Knob 1 and Soft Knob 2 as well as INC and DEC buttons to scroll through the sounds in the currently selected bank.

    D["BANK"] --> E["Turn to scroll through User and Factory banks"]
    F["PROGRAM"] --> G["Turn to scroll through programs 1-128 in each bank"]

Bank and Program controls

Each of the factory presets has interesting and useful modulation functions programmed into the touch slider and the mod wheel. While you're trying out the factory sounds, play with these performance controls and listen how the sound changes. Each preset also has a pre-programmed sequence. To hear it, press the PLAY button in the SEQ section.

Using the Main Display

The most frequently used controls on the Pro 3 are on its front panel. But there are many additional controls (as well as numeric display of values) visible in its main display.

For example, adjusting a knob or switch in the OSCILLATORS section reveals the tuning, shape, and level menus in the display. The display also reveals parameters not found on the front panel such as OSC SLOP and WAVE RESET (in Tab 2). You can select and edit these additional parameters using the four Soft Knobs and Soft Buttons located above and below the display.

The Soft Knobs are for dialing in values. The Soft Buttons select between various menu tabs.

The Main Display

Sound Banks

The Pro 3 contains a total of 1024 programs. Banks U1-U4 are user banks that can be overwritten. Banks F1-F4 are factory banks that are permanent. As shipped, user banks U1-U4 are identical to permanent factory banks F1-F4. Each bank has 128 programs (multiplied by 4 banks = 512 programs each). You can edit the programs of either bank, but you can only save them to user banks U1-U4.

Banks of non-rewritable, permanent sounds are included so that they are always available, to be used as is, or as templates for new sounds of your own. It’s easy to design a new sound by tweaking an existing one.

Bank and Program controls

Selecting Programs

Use the BANK and PROGRAM knobs to select and recall programs.

To choose a program:

1. Turn the BANK knob to select the bank you want.
2. Turn the PROGRAM knob to select a program within that bank.

Editing Programs

Because the majority of the sound-shaping controls of the Pro 3 appear on its front panel, editing an existing program is simple: turn a knob and listen to its effect. Keep turning knobs and pressing buttons. If you like what you’ve created, save the program by pressing the WRITE button twice. (See “Saving a Program” on page 10 for more options when you save.)

The rotary controls on the front panel are a mixture of rotary encoders (which have no position indicator) and potentiometers or “pots,” which have a position indicator and a finite travel range from left to right. You can choose between three different modes that determine how the synth reacts when you edit its parameters with a pot. For details, see page 98.

Comparing an Edited Program to its Original State

When editing a program, it's often useful to compare its edited state to its original state to evaluate your edits.

To compare an edited program to a saved version:

1. Edit a program, then press the COMPARE button.
2. Play the keyboard to hear the saved version of the sound.
3. To disable the compare function and return to the edited sound, press the COMPARE button again to turn it off. Programs can't be written while in compare mode.

When editing a program press to hear the saved version for comparison Write Compare Global Play List Cutoff DriveResonance Filter Type 60 60 20 Ladder CUTOFF RESONANCE DRIVE Filter Type Filter Filter Misc ADSR Filter Type

It's also useful to be able to check the value of a parameter for reference. Normally, to make a parameter value appear in the display, you have to turn the parameter's knob — which will change the parameter value. But there is a way to do this without changing the value:

To check the value of a parameter without changing it:

1. Press the show button.

2. Turn any parameter knob. The value appears in the display.

3. To return to normal operation, press the show button again to disable it.

Using the Show button to display a parameter value

Creating a Program from Scratch

An existing program can be very useful as a jumping off point for new sounds. But it's also useful (and educational) to create a new sound from scratch. The Pro 3 makes this easy by providing a “basic preset” that you can quickly recall at any time. This preset is very simple, with a single oscillator as its basis.

To recall the basic program:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to scroll through the commands and select BASIC PROGRAM in the display menu.
3. Press soft button 1 (WRITE NOW). The current sound settings are reset to the basic program.
4. Press the GLOBAL button again to return to normal operation. From here you can begin creating your own sound using the basic program as a starting point.

Chapter 3 provides a selection of simple sound design tutorials. It’s designed to give you a basic working knowledge of how to use the Pro 3 to make your own sounds. See “Chapter 3: Programming the Pro 3” on page 104.

Saving a Program

If you've created a sound that you like, you'll probably want to save it. Saving a program overwrites a previously saved program. Sound designers often save many incremental versions of a program as they continue to refine it. These intermediate versions often make good jumping off points for new sounds.

To save a program to the same preset location:

1. Press the WRITE button. Its LED begins blinking.
2. Enter a name for the program using the appropriate Soft Knobs and Soft Button. (See the illustration that follows for their functions.)
3. Press the WRITE button again. Its LED stops blinking and the program is saved.

To save a program to a different location:

1. Press the WRITE button. Its LED begins blinking.
2. Turn the BANK or PROGRAM knobs (or Soft Knob 1 and Soft Knob 2) to select a new location. You can only save to banks U1-U4.
3. Enter a name for the program using the appropriate Soft Knobs and Soft Buttons. (See the illustration that follows for their functions.)

Press the WRITE button again. Its LED stops blinking and the program is saved.

Saving a Program

Canceling Save

Sometimes you may want to cancel saving a program before you commit.

To cancel the save process before you commit:

- If the WRITE button LED is flashing, press the GLOBAL button. The WRITE LED stops flashing and saving is canceled. You can return to editing if you want.

Comparing Before You Save

Before saving a program to a new location, it's a good idea to listen to the program in the target location to make sure you really want to overwrite it.

To evaluate a program before you overwrite it:

1. Get ready to save by pressing the WRITE button. It starts flashing.

2. Press the COMPARE button. Its LED lights up.

3. Use the BANK and PROGRAM knobs to navigate to the sound you want to audition and play the keyboard to hear the sound in the target location.

4. If you don't want to overwrite that location, use the Bank and Program knobs to select other possible locations to audition.

5. Once you have found a location to overwrite, press the COMPARE button again to turn it off. (Programs can't be written while in compare mode.)

6. The WRITE button is still flashing and ready to save. Press WRITE and the sound is saved.
7. Alternatively, if you want to cancel saving and continue editing, press the GLOBAL button. Saving is canceled.

You can use the GLOBAL button to set the program that appears when you power on the Pro 3. Simply use the BANK and PROGRAM knobs to find the program you want, then press the GLOBAL button twice. That program is now the default program on start up.

Using Paraphonic Mode

The Pro 3 was designed primarily as a monophonic instrument. But we added a 3-voice paraphonic playback mode for extra performance power. In this mode, the three oscillators can be triggered independently, each with its own amplifier envelope. (However, the filter and its envelope are shared between the three oscillators.) This gives you the ability to play chords of up to 3 notes.

Make sure to select a waveshape for oscillator 3 since it's possible to set this oscillator to OFF. Each oscillator is triggered with an envelope set by the VCA shape.

Revert Write Show Compare Misc Params Global Paraphonic Play List Press the Paraphonic button to enable 3-voice paraphonic mode. Cutoff DriveResonance Filter Type 60 CUTOFF 60 RESONANCE 20 Ladder Filter Filter Misc ADSR Env Amt

To enable paraphonic playback:

1. Press the PARAPHONIC button.
2. Turn up the levels of all three oscillators in the MIXER.
3. Play some chords.
4. Adjust the Octave and oscillator waveshapes as necessary.

With clever programming you can create complex sounds that work well in paraphonic mode. Add a bit of pulse width modulation or chorused delay to create interesting string and pad sounds.

Exploring the Pro 3 in Greater Depth

Before you explore the sound creation possibilities of the Pro 3, we'd like to point you toward a few things that will help you tailor it to your needs. The better you know it, the more you'll get out of it.

First, read “Global Settings” on page 96. There are many useful settings and functions found in the Global menu that will affect the overall behavior of your Pro 3, including tuning, MIDI connections, calibration, and more. In particular, read about Pot Modes and determine which works best for you when you’re editing sounds.

Also, in “Rear Panel Connections” on page 2 read about the various connectors on the back of your Pro 3 and how you can use its various pedal, audio, MIDI, and USB inputs and outputs.

Finally, be on the lookout for tips and notes scattered throughout this manual to gain a better working knowledge of the Pro 3. We wish you many hours of musical exploration!

Chapter 2: Pro 3 Controls

This chapter explains all of the controls on the Pro 3, section by section.

As explained in Chapter 1, the most frequently used Pro 3 controls are located on its front panel, with additional controls (as well as numeric display of values) visible in its main display.

Adjusting a knob or switch in the Mixer section reveals the three oscillator level parameters and noise level parameter in the display. The display also reveals additional parameters not found on the front panel such as external input level, gate threshold, and more. You can select and edit these additional parameters using the four Soft Knobs and Soft Buttons located above and below the display.

The Soft Knobs are detented encoders for dialing in values. The Soft Buttons select between various menu tabs.

Oscillators

Oscillators generate the raw building blocks of the Pro 3's sound by producing waveforms, each of which has its own sound character based on its harmonic content. The Pro 3 has two analog, voltage-controlled oscillators and one digital wavetable oscillator.

Oscillators 1 and 2 generate triangle, sawtooth, and pulse waves. You can vary the “pulse width” of these waveshapes using the SHAPE MOD parameter. This allows for a variety of different waveshapes and timbres.

Shape Mod value: 0 Shape Mod value: 254

Oscillator 3, because it's digital, generates not only triangle, sawtooth, super saw, and pulse waves but also complex, wavetable-derived wave shapes.

sawtooth triangle pulse/square OSC 1 OCTAVE PITCH SHAPE SHAPE MOD SYNC OSC 2 OCTAVE PITCH SHAPE SHAPE MOD SYNC OSC 3 OCTAVE PITCH SHAPE SHAPE MOD LOW FREQ OSCILLATORS

The Oscillators section

To listen to the oscillators:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).
3. In the basic program, only Oscillator 1 is audible. (The levels of Oscillators 2 and 3 are set to zero by default.)
4. Hold down a note on the keyboard and in the OSCILLATORS section, turn the SHAPE knob left and right to hear the waveshape change from triangle to sawtooth to pulse. (Sawtooth is selected by default in the basic program.)
5. With a specific waveshape selected, turn the SHAPE MOD knob and listen to how the timbre of the waveshape changes. Note that when using SHAPE MOD with the pulse wave, it's possible to make the pulse width so narrow that the sound "disappears."
6. Be aware that on Oscillator 3, when SUPER SAW is selected as the wave-shape (refer to the display to see the name of the waveshape), SHAPE MOD controls the detuning of the Super Saw wave.
7. Turn up the level of Oscillator 2 in the Mixer and experiment with setting each oscillator to a different waveshape. Experiment with the PITCH knob on the oscillators and notice how slightly detuning the oscillators in relation to each other creates movement and thickness in their combined sound. Try tuning one oscillator to a interval such as a third, a fifth, or a sixth.
8. Experiment with the OCTAVE knob on the oscillators and notice how setting each oscillator to different octave influences their combined sound. This is especially true when using all three oscillators together.
9. Choose one of the three filter types and rotate the filter's CUTOFF and RESONANCE knobs to see how this affects the sound of the oscillators.
10. With Oscillator 1 and 2 on, press the SYNC button on Oscillator 1, and set it's OCTAVE to 5. Then rotate the PITCH knob on Oscillator 1 while you hold a note. This is the classic hard sync sound that you've probably heard before. Instead of rotating the PITCH knob by hand, you can use the modulation matrix to route an envelope to Oscillator 1 to sweep the oscillator's pitch and create this effect each time you play a note. You'll learn more about the mod matrix in "Modulation" on page 46.

Exploring Oscillator 3

Because Oscillator 3 is a digital wavetable oscillator, it generates a variety of waveshapes. In addition to the standard, static waveshapes of sine, sawtooth, super saw, and pulse waves, it provides 32 wavetables, each with 16 different waves within that table.

Once you select one of the 32 wavetables with the SHAPE knob, you can then select a wave within the wavetable using the SHAPE MOD knob. When you turn the SHAPE MOD knob, you'll hear the waveshapes morph smoothly from one to the next as the Pro 3 interpolates between them.

If you select one of the 32 wavetables, you can then select a specific static wave. Or, if you use an LFO or the modulation matrix to control SHAPE MOD, you can sweep through the selected table's 16 waves to create timbres that shift and evolve in interesting ways.

To listen to Oscillator 3:

1. Press the GLOBAL button. Use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).

2. In the basic program, only Oscillator 1 is audible. The levels of Oscillators 2 and 3 are set to zero in the Mixer by default.

3. In the MIXER section, turn down the level of Oscillator 1 and turn up the level of Oscillator 3.

4. Play and hold a note on the keyboard. In the OSCILLATORS section, turn the SHAPE knob on Oscillator 3 to select one of the 32 wavetables. The first choices are sine, sawtooth, super saw, and pulse, after that are wavetables 1-32

5. Turn the SHAPE MOD knob to select a waveshape within the currently selected wavetable. When you turn the knob, you'll hear the wave-shapes morph smoothly from one to the next.

To use an LFO to sweep through the waves in a wavetable:

1. Use the SHAPE knob on Oscillator 3 to select one of the 32 wavetables.

2. In the LFO section, press the LFO 3 button, then the DESTINATION button.

3. In the display, choose osc 3 SHAPEMOD as the destination.

4. Hold down a note on the keyboard and listen as you set the FREQUENCY and AMOUNT of LFO 3 modulation as desired. Higher FREQUENCY settings sweep through the wavetable faster. Higher AMOUNT settings sweep though a wider range of waves in the wavetable.

Oscillator Parameters (Front Panel)

Shape: Selects the waveshape generated by the oscillator. Oscillators 1 and 2 produce triangle, sawtooth, and pulse analog waveshapes. These waveshapes are continuously variable. Oscillator 3 produces triangle, sawtooth, super saw, and pulse waves, plus 32 wavetables containing 16 waves each.

Octave: Sets the base frequency of an oscillator over a 5-octave range. The global MASTER COARSE and MASTER FINE settings affect the pitch of the oscillators. See “Global Settings” on page 119 for more information.

Pitch: -700...+699—Fine tune control with a range of 7 semitones (a major 5th) up or down. The 12 o'clock position is centered.

Shape Mod: On Oscillator 1 and 2, this changes the “pulse” width of the selected waveform, which modifies its harmonic content and timbre. To generate a square wave when PULSE is selected as the waveform, set this parameter to 0. On Oscillator 3, this knob selects a waveshape within the currently selected wavetable. If SUPER SAW is selected as the waveshape, SHAPE MOD controls the thickness (detuning) of the Super Saw.

Applying waveshape modulation using an LFO or other modulation source in the mod matrix is a great way to add movement to a sound.

Sync: Off, On—Turns on oscillator hard sync. When an oscillator is hard synced, its wave cycle is slaved to another oscillator's wave cycle and is forced to reset each time the master oscillator's wave cycle restarts. This causes the slaved oscillator to create harmonically complex waveforms — particularly when the slave oscillator's pitch is set higher than the master oscillator's pitch. See page 110 to learn how to set up a classic oscillator hard sync sound.

Oscillator 1 Oscillator 2 Oscillator 1 synced to Oscillator 2

Oscillator hard sync

Low Freq: Turns Oscillator 3 into an LFO (low frequency oscillator) so that it can be used for modulation. Since Oscillator 3 is a wavetable oscillator, the variety of waveshapes it produces is far greater than LFOs 1-3 and it can be used to create many interesting modulation effects.

Additional Oscillator Parameters (Display Menus)

Additional oscillator parameters are accessible through the menus in the main display. To see these menus, adjust any control in OSCILLATORS section of the front panel. The parameters explained below do not appear on the front panel.

TAB 1 - Osc Tuning

Shape Wave ResetShape Mod Osc Slop 0 5-1 □ SHAPE SHAPE MOD WAVE RESET OSC SLOP Osc1 LevelOsc1 TuningOsc1

Osc1 Shape

Wave Reset: Off, On—(In the osc1 SHAPE tab in the display) When Wave Reset is off, the Pro 3 oscillators are free running. That is, the oscillators are running whether a note is being gated on or not. When the amplifier envelope is set for a fast attack, this can cause a soft, but detectable, pop or click at the beginning of a note because the note might be gated on at a point in the wave's cycle other than a zero crossing. The first cycle to play might be truncated. For some sounds, like monophonic basses, this may actually be desirable. It adds a bit of randomness to the attack that can make it sound more organic. When WAVE RESET is on, the wave is always reset to zero (the start of its cycle) when a note is triggered.

Osc Slop: 0...127—Adds random detuning to add or enhance the natural pitch drift of the chosen oscillator. Vintage analog synthesizers all had a certain amount of natural pitch drift which added to the warmth of their sound. Smaller amounts of oscillator slop are subtle and add a more organic feel. Larger amounts create a pronounced “out of tune” effect.

TAB 3 - Osc Level

Osc 1 127 OSC 1 0 SHAPE MOD WAVE RESET OSC SLOP Osc1 Level Osc1 Tuning Osc1

Osc Level: 0...127—Sets the output level for the selected oscillator. When using all three oscillators at once, especially with high levels of RESONANCE or DRIVE, it may be necessary to reduce their levels to avoid distortion (unless desired).

TAB 4 - Osc Misc

Glide Rate 0 GLIDE RATE Osc1 Level0 Osc1 Misc

Glide Rate: 0...127—Sets the oscillator glide (portamento) amount.

Glide causes the pitch of a note to glide smoothly up or down from the pitch of the previously played note. It can be set independently for each oscillator. Low values are shorter/faster. The GLIDE switch must be on to hear the effect of GLIDE RATE. For a detailed explanation, see “Glide” on page 83.

Mixer

The Mixer section is where you set the levels of the various sound generators on the Pro 3. These include oscillators 1-3, the noise generator, and an external input when connected to the rear panel input of the Pro 3. You must turn up at least one of these sources in order to make sound with the Pro 3. Alternatively, when using Low-pass 1 or Low-pass 2, you can make the filter generate its own sine wave by turning up RESONANCE all the way so that it self-oscillates. The State-Variable filter doesn't self-oscillate.

Rather than limit the outputs of the Pro 3 to keep the instrument from clipping, we allow you to adjust levels at various points in its signal path. This gives you the option of "overloading" things in interesting ways, if you wish to do so. If not, try reducing the levels of the oscillators in the MIXER section, turning down the DRIVE and RESONANCE parameters in the Filter section, or the AMOUNT parameter in the Amp Envelope section.

Osc 1 Level: 0...127—Sets the output level of oscillator 1.

Osc 2 Level: 0...127—Sets the output level of oscillator 2.

Osc 3 Level: 0...127—Sets the output level of oscillator 3.

Ext Audio: 0...127—Sets the output level of an external signal connected to the AUDIO IN jack on the rear panel of the Pro 3.

Noise: 0...127—Sets the output level of the noise generator.

Additional Mixer Parameters (Display Menu)

Additional Mixer parameters are accessible through the menus in the main display. To see these menus, adjust any control in MIXER section of the front panel. The parameters explained below do not appear on the front panel.

Input Gain: 0...127—Boosts the input level of any signal connected to the AUDIO IN connector on the rear panel of the Pro 3. This is useful for increasing the gain of low-level output devices such as guitars.

In Gate Thresh: 0...127—Sets the threshold above which external input signals will trigger the Pro 3's. Triggering from an external audio input allows you to drive the Pro 3's Sequencer steps with guitars, drum machines and other devices.

Input Release: 0...127—Sets the release speed of the envelope follower. Use this to fine tune the response of the envelope follower when triggering the Sequencer from an external device connected to the AUDIO IN jack on the rear panel of the Pro 3.

Filters

The Pro 3 has three different filters, each of which has its own unique character:

• LOW-PASS 1 - 4-POLE OTA is a 4-pole, 24 db-per-octave resonant filter based on the Sequential Prophet-6 filter. It can self-oscillate (generate a sine wave) when RESONANCE is set to its maximum.
• LOW-PASS 2 - 4-POLE LADDER is a classic 4-pole, 24 db-per-octave resonant transistor ladder filter. It can self-oscillate when RESONANCE is set to its maximum
• STATE-VARIABLE - 2-POLE OTA is a 2-pole, 12 db-per-octave filter based on the Sequential OB-6 filter. It features low-pass, band-pass, high-pass, and notch operation. The State-Variable filter cannot self-oscillate.

Another characteristic of the State-Variable filter is that increasing the amount of RESONANCE does not decrease the amount of low-frequencies (bass). On Low-pass 1 and Low-pass 2, increasing the amount of RESONANCE de-emphasizes low frequencies. The BP and STATE controls apply only to the State-Variable filter.

The differences between these filters can be subtle or dramatic, depending on their individual settings, the amount of filter resonance applied, and other factors. The function of the filters is to subtract frequencies from the sound produced by the oscillators, noise generator, and/or external audio input, thereby changing the overall harmonic content of the synth's sound. This change is varied over time using the Filter Envelope to produce more dynamic timbres.

DRIVE NOTCH LP STATE HP CUTOFF RESONANCE BP 4-Pole OTA 4-Pole Ladder 2-Pole OTA LOW-PASS 1 LOW-PASS 2 STATE-VARIABLE FILTER

Press one of these buttons to select the filter type

To hear the effect of the filter:

1. Recall the Basic Program by pressing the GLOBAL button and using Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).
2. Press the LOW-PASS 1 button to select this filter.
3. Hold down a note and rotate the filter's CUTOFF knob. Notice how it cuts the high frequencies as you rotate counter-clockwise, making the sound of the oscillator less bright. If you turn the CUTOFF knob fully counter-clockwise you'll filter out all frequencies and hear nothing.
4. Return the CUTOFF knob to its halfway position, hold down a note again then turn the RESONANCE knob about halfway up.
5. Rotate the filter's CUTOFF knob again and listen to the sound change as a band of frequencies near the cutoff is amplified. This how to create a classic resonant filter sweep.

In the previous example, you controlled the filter cutoff by hand. In most cases, you will use the Filter Envelope to do this. To learn more about the Filter Envelope see page 31.

Exploring the State-Variable Filter

As its name suggests, the State-Variable filter can change its operational mode/state from low-pass, to notch, to high-pass, with a separate band-pass mode that you can activate using the BP (band-pass) button. This makes the State-Variable filter very versatile.

Exploring the State-Variable filter:

1. Press the GLOBAL button and use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).
2. Press the STATE-VARIABLE button to select this filter.
3. Turn the STATE knob all way to the left so that the filter is set to LP (low-pass mode).
4. Hold down a note and rotate the filter's CUTOFF knob. Notice how it cuts the high frequencies as you rotate counter-clockwise, making the sound less bright.
5. Turn the filter's STATE knob to NOTCH and rotate the CUTOFF knob again. Listen to the effect as the filter cuts a band of frequencies centered around the cutoff frequency.
6. Now turn the filter's STATE knob to HP (high-pass) and rotate the CUTOFF knob again. Listen to the effect as the filter removes the low-frequencies from the sound.
7. Now press the BP (band-pass) button and rotate the CUTOFF knob again. This time, the filter removes frequencies above and below the cutoff frequency.
8. Finally, turn the resonance knob to it's center positions and repeat steps 3-6 to hear the effect.

Note that there are many intermediate states between the LP, NOTCH, and HP settings. This is one of the reasons that the State-Variable filter is so versatile.

Modulating the state-variable filter's operating mode with an envelope or LFO can create many unique and interesting sounds. Set the modulation source to LFO and the destination to SV LP-N-HP.

Filter Parameters (Front Panel)

Filter Type Buttons: Low-Pass 1, Low-Pass 2, State-Variable—These select the filter type. Low-Pass 1 is a 4-pole, 24 db per-octave resonant filter based on the Sequential Prophet-6. Low-Pass 2 is a classic 4-pole, 24 db per-octave ladder filter. State-Variable is a 2-pole, 12 db per-octave filter based on the Sequential OB-6, with low-pass, notch, high-pass, and band-pass modes.

Drive: 0...127—Increases signal input to the filter, boosting volume and adding harmonic saturation and warmth.

Cutoff: 0...164—Sets the filter's cutoff frequency.

Resonance: 0...255—Emphasizes a narrow band of frequencies around the cutoff frequency. High levels of resonance can cause the Low-Pass 1 and Low-Pass 2 to self-oscillate and generate its own pitch. The State-variable filter does not self oscillate at the maximum resonance setting.

High levels of resonance can sometimes cause the Pro 3 outputs to clip. To remedy this, reduce oscillator levels in the Mixer, or reduce the Amp Envelope's AMOUNT parameter.

State: LP, Notch, HP, BP—This knob selects the State-Variable filter's mode of operation. It transitions smoothly from low-pass to notch to high-pass operation, allowing a blending of these modes. Band-pass operation is selected with the BP switch. Each filter mode has its own characteristic sound and function. As noted previously:

• Low-pass: passes frequencies below the cutoff frequency
• Notch: removes frequencies in a notch centered around the cutoff frequency
  • High-pass: passes frequencies above the cutoff frequency
• Bandpass: passes a band of frequencies centered around the cutoff frequency

On the front panel, band-pass mode is selectable only through the BP on/off switch. However, you can actually smoothly transition between normal and band-pass operation by choosing SEM-NORMAL-BP as a modulation destination in the mod matrix.

BP: On, Off—Switches the State-variable filter to band-pass mode.

Additional Filter Parameters (Display Menus)

Additional Filter parameters are accessible through the menus in the main display. To see these menus, adjust any of controls in FILTER section of the front panel. The parameters explained below are the ones that don't already appear on the front panel.

TAB 2 - Filter Misc

LP-Notch-BP BdPass-Notch Key>LPF FRQ Env Amt LP-NOTCH-HP BDPASS-NOTCH 028 KEY>LPF FREQ LADDER RES COMP ADSRFilter Env Amt Misc

Key>LPF Freq: 0...127—Sets the amount of modulation from the keyboard to the filter's cutoff frequency. Any setting above zero means that the higher the note played on the keyboard, the more the filter opens. This is useful for adding brightness to a sound as higher notes are played, which is typically how acoustic instruments behave. When set to zero, keyboard filter tracking is off, meaning that filter frequency is unaffected by playing higher or lower notes on the keyboard. When set to 127, the filter will track in half-step increments, which can be useful if you are using the filter to generate a pitch through self-oscillation.

Ladder Res Comp: On, Off—In a classic ladder filter, increasing the amount of resonance decreases the amount of bass response. This parameter compensates for this by boosting bass frequencies as resonance is increased on Low-Pass 2 Filter. This parameter is on by default.

TAB 3 - ADSR

Attack: 0...127—Sets the attack time of the envelope. The higher the setting, the slower the attack time and the longer it takes for the filter to open from the level set with the filter CUTOFF knob to the level set by the filter envelope amount. Percussive sounds typically have sharp (short) attacks.

Decay: 0...127—Sets the decay time of the envelope. After a sound reaches the filter frequency set at its attack stage, DECAY controls how quickly the filter then transitions to the cutoff frequency set with the SUSTAIN knob. The higher the setting, the longer the decay. Percussive sounds, such as synth bass, typically have shorter decays (and a generous amount of low-pass filter resonance).

Sustain: 0...127—Sets the filter cutoff frequency for the sustained portion of the sound. The sound will stay at this filter frequency for as long as a note is held on the keyboard.

Release: 0...127—Sets the release time of the envelope. This controls how quickly the filter closes after a note is released.

The description of envelope behavior just given is true when the AMOUNT parameter is set to a positive value. But since this control is actually bipolar, it is possible to set a negative amount of modulation. In this case, the envelopes are inverted and their behavior changes. The best way to get a feel for the difference is to experiment with both positive and negative settings of the AMOUNT parameter.

The cutoff frequency setting may limit the effect of the envelope on the filter. For example, in low-pass filter mode, if CUTOFF is at its highest setting, a positive envelope amount will have no effect on the filter since the filter is already completely open.

TAB 4 - Env Amt

Amount DelayVel On/Off Env Loop Amt:+25 Vel:On Del:0 Loop:Off ADSR Amt

Amount: -127...127—Sets the amount of modulation from the filter envelope to the filter's cutoff frequency. Any setting above zero means that each time you strike a key, the filter envelope controls how the filter opens and closes. Higher amounts more dramatically affect the cutoff frequency. This control is bipolar. Positive settings produce standard behavior. Negative settings invert the envelope.

Velocity On/Off: On, Off—Allows key velocity to influence filter cutoff frequency. If on, the harder you play, the more the filter will open and the brighter the sound will be. If off, key velocity will not affect the filter. This control allows for more touch-sensitive sounds.

Delay: 0...127—Sets a delay between the time the envelope is triggered and when the Attack and subsequent stages occur.

Loop: Off, On—When on, the Delay, Attack, and Decay segments of the envelope repeat. Sustain still affects the level at which the Decay segment ends, but instead of sustaining at a fixed level while a note is triggered, Delay, Attack, and Decay loop until the note is turned off. The Release segment begins when the note is released, just as it does when Repeat is off.

Filter Envelope

The Pro 3 filter has a dedicated, 5-stage envelope generator (attack, decay, sustain, release, plus delay). The Filter Envelope is used to shape the harmonic characteristics of a synthesized sound by giving you filtering control with these stages.

This is one of the most important aspects of a synthesized sound. Without an envelope, the filters would be static and unchanging. They would stay open or closed by a fixed amount that wouldn't change over the duration of a sound. That's not very expressive or interesting to listen to — and it's not how most real-world instruments behave.

In general, sounds produced by an acoustic instrument are brighter at their beginning (the attack stage) and grow mellower as they die out (the decay and release stages). In other words, their harmonic content changes over time. This is exactly what the filter envelope is designed to emulate.

FILTER

Filter Envelope

A typical 5-stage DADSR envelope

To hear the effect of the Filter Envelope:

1. Press the GLOBAL button and use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).
2. Press the LOW-PASS 1 button to select this filter type.
3. Hold down a note and rotate the filter's CUTOFF knob to set it to a value of 40 (refer to the main display to see its numeric value).
4. Play a note. At this point you may not hear anything because you've closed the filter significantly.
5. In the Envelopes section, turn the Filter Envelope's AMOUNT knob to a value of 50 (refer to the main display to see its numeric value).
6. Play a note. Notice how the sound has changed. The Filter Envelope is controlling filter cutoff by the amount you set with the AMOUNT knob.
7. Repeatedly strike a note on the keyboard as you turn the Filter Envelope's DECAY knob clockwise and counterclockwise. Notice how it changes the sound as the note decays faster or slower after its initial attack stage.
8. Now experiment with the Filter Envelope's ATTACK knob. Notice how the attack becomes faster or slower.
9. Now hold down a note and experiment with the Filter Envelope's SUSTAIN knob. This controls how wide the filter stays open while you hold down a key on the keyboard.
10. The Filter Envelope's RELEASE parameter acts in conjunction with the Amplifier Envelope, so to hear its effect, first set the Amp Envelope's RELEASE value to 75.
11. Now repeatedly strike a note on the keyboard as you turn the Filter Envelope's RELEASE knob clockwise and counterclockwise. Notice how the note fades out faster or slower as you change the RELEASE value.
12. Continue experimenting with various Filter Envelope settings while you adjust the Filter Envelope's ENV AMOUNT knob. Notice how greater AMOUNT settings amplify the effect of the envelope on the filter.

As noted above, the Filter Envelope and Amplifier Envelope often work in conjunction, with the Filter Envelope controlling how the filter opens and closes and the Amplifier Envelope controlling how the Amplifier controls the overall volume shape of the sounds you create. To learn more about the Amplifier Envelope, see page 35.

Envelope Parameters (Front Panel)

Attack: 0...127—Sets the attack time of the envelope. The higher the setting, the slower the attack time and the longer it takes for the filter to open from the level set with the filter CUTOFF knob to the level set by the filter envelope amount. Percussive sounds typically have sharp (short) attacks.

Decay: 0...127—Sets the decay time of the envelope. After a sound reaches the filter frequency set at its attack stage, DECAY controls how quickly the filter then transitions to the cutoff frequency set with the SUSTAIN knob. The higher the setting, the longer the decay. Percussive sounds, such as synth bass, typically have shorter decays (and a generous amount of low-pass filter resonance).

Sustain: 0...127—Sets the filter cutoff frequency for the sustained portion of the sound. The sound will stay at this filter frequency for as long as a note is held on the keyboard.

Release: 0...127—Sets the release time of the envelope. This controls how quickly the filter closes after a note is released.

Velocity On/Off: On, Off—Allows key velocity to influence filter cutoff frequency. If on, the harder you play, the more the filter will open and the brighter the sound will be. If off, key velocity will not affect the filter. This control allows for more touch-sensitive sounds.

Amount: -127...127—Sets the amount of modulation from the filter envelope to the filter’s cutoff frequency. Any setting above zero means that each time you strike a key, the filter envelope controls how the filter opens and closes. Higher amounts more dramatically affect the cutoff frequency. This control is bipolar. Positive settings produce standard behavior. Negative settings invert the envelope.

Additional Filter Envelope Parameters (Display Menus)

Additional Filter parameters are accessible through the menus in the main display. To see these menus, adjust any of the filter envelope controls in the ENVELOPES section of front panel. The envelope parameters are in menu Tab 3 and Tab 4. The parameters explained below are the ones that don't appear on the front panel.

TAB4 - Env Amount

Amount DelayVel On/Off Env Loop Amt:+25 Vel:On Del:0 Loop:Off ADSR Amt

Delay: 0...127—Sets a delay between the time the envelope is triggered (note on) and when the attack portion actually begins.

Loop: Off, On—When on, the Delay, Attack, and Decay segments of the envelope repeat. Sustain still affects the level at which the Decay segment ends, but instead of sustaining at a fixed level while a key is pressed, Delay, Attack, and Decay loop until the key is released. The Release segment begins when the key is released, just as it does when Repeat is off.

Amplifier Envelope

After passing through the filters, a synthesized sound goes into an amplifier, which controls its overall volume. The amplifier has a dedicated, 5-stage envelope generator (attack, decay, sustain, release, plus delay) which is used to shape the volume characteristics of a sound over time by giving you control over these stages. Along with the filter envelope, this is one of the most important aspects of a synthesized sound.

Without a volume envelope, the volume of a sound wouldn't change over the duration of a note. It would begin immediately, remain at its full volume for its duration of the note, then end immediately when the note was released. Again, that's not very interesting sonically and it's not typically how instruments behave in the real world.

To give you a real-world example, the main difference between the sound of the wind and the sound of a snare drum is that they have very different volume envelopes. Otherwise, they are essentially both white noise.

Wind has a relatively slow attack, a long sustain, and a long decay and release. A snare drum has a sharp attack, no sustain, and very little decay or release. But again, they are both fundamentally white noise.

AMP VELOCITY ATTACK DECAY SUSTAIN RELEASE AMOUNT ENVELOPES

Amplifier Envelope

A typical 5-stage, DADSR envelope

As noted previously, the Amplifier Envelope often works in conjunction with the Filter Envelope, with the Filter Envelope controlling how the filter opens and closes and the Amplifier Envelope controlling how the Amplifier controls the overall volume shape of the sounds you create.

To hear the effect of the Amplifier Envelope:

1. Press the GLOBAL button and use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).
2. Repeatedly strike a note on the keyboard as you turn the Amplifier Envelope's ATTACK knob clockwise. Notice how the attack becomes slower and more gradual the further you turn the knob.
3. Reset the ATTACK parameter to zero.
4. Next, repeatedly strike a note on the keyboard as you turn the Amplifier Envelope's SUSTAIN to zero. Notice how it changes the sound so that the sound no longer sustains even if you hold down the key. The only sound you hear is the decay portion of the sound.
5. Now, with SUSTAIN still set to zero, repeatedly strike a note on the keyboard as you turn the Amplifier Envelope's DECAY knob clockwise and counterclockwise. Notice how it changes the sound as the note decays faster or slower after its initial attack stage.
6. Reset the DECAY parameter to 127
7. Finally, with DECAY set to 127 and SUSTAIN still set to zero, repeatedly strike a note on the keyboard as you turn the Amplifier Envelope's RELEASE knob clockwise. Notice how the release becomes longer the further you turn the knob.
8. Continue experimenting with various Amplifier Envelope settings while you also adjust the Filter Envelope to hear how these two controls interact. You will understand how powerful the envelopes are and how essential they are to designing sounds.

Amplifier Envelope Parameters (Front Panel)

Attack: 0...127—Sets the attack time of the envelope. The higher the setting, the slower the attack time and the longer it takes for a sound to reach its full volume. Pads typically have softer (longer) attacks. Percussive sounds have sharper (shorter) attacks.

Decay: 0...127—Sets the decay time of the envelope. After a sound reaches its full volume at its attack stage, DECAY controls how quickly the sound transitions to the level set with the SUSTAIN control. The higher the setting, the longer the decay. Percussive sounds, such as synth bass, typically have shorter decays.

Sustain: 0...127—Sets the sustain level of the envelope. The higher the setting, the louder the sustained portion of the sound will be. The sound will stay at this level for as long as a note is held on the keyboard.

Release: 0...127—Sets the release time of the envelope. This controls how quickly a sound dies out after a note is released.

Env Amount: 0...127—Sets the amount of modulation from the Envelope to the VCA. In most cases you will probably want to set this fully clockwise for maximum VCA volume. If you experience signal clipping, try reducing the ENV AMOUNT.

To create a “gated VCA” effect, set the AMOUNT of the Amplifier Envelope to zero, route the LFO square wave to ENV VCA AMT with an AMOUNT setting of 127, and hold a note.

Velocity On/Off: On, Off—Allows key velocity to influence volume. If on, the harder you play, the louder sound will be. If off, key velocity will not affect the volume. This control allows for more touch-sensitive sounds.

Additional Amplifier Parameters (Display Menus)

Additional Amplifier Envelope parameters are accessible through the menus in the main display. To see these menus, adjust any of the controls in AMP portion of the ENVELOPES section of the front panel. The parameters explained below are the ones that don't appear on the front panel.

TAB 1 - VCA

Volume: 0...127—Sets the volume of the currently active program. Although the master output level of the Pro 3 is controlled by the front-panel MASTER VOLUME knob, the VOLUME parameter in this menu sets the volume of an individual program. This is useful for ensuring that your sounds have roughly the same volume from program to program.

Delay: 0...127—Sets a delay between the time the envelope is triggered (note on) and when the attack portion actually begins.

Loop: Off, On—When on, the Delay, Attack, and Decay segments of the envelope repeat. Sustain still affects the level at which the Decay segment ends, but instead of sustaining at a fixed level while a note is gated on, Delay, Attack, and Decay loop until the note is turned off. The Release segment begins when the note is gated off, just as it does when Repeat is off.

Auxiliary Envelopes

The Pro 3 has two additional 5-stage envelope generators (attack, decay, sustain, release, plus delay). They are useful for creating modulation that varies over time according to the shape of the envelope. Routing an envelope to an oscillator's frequency, for example, causes the oscillator's pitch to rise and fall according to the contour of the envelope.

As with all of the Pro 3's envelopes, there are controls for modulating the envelope amount using keyboard velocity. The Auxiliary Envelopes can be routed to any of the modulation destinations in the mod matrix. In addition, the Auxiliary Envelopes can repeat (loop) using the REPEAT function in the aux envelopes display menu. This is useful for cyclical 4-stage modulation.

There are many ways to make creative use of the Auxiliary Envelopes:

• Route an Auxiliary Envelope to one of the oscillators' COARSE FREQ parameter to create the classic “pitch blip” effect used in many synth lead sounds.
• Route an Auxiliary Envelope to the filter's CUTOFF parameter (in addition to the standard Filter Envelope) to create a more complex filter envelope shape.
• Route an Auxiliary Envelope to one or more of the oscillators' SHAPE parameter to make their timbre evolve according to envelope's contour.
• Route an Auxiliary Envelope with a fast attack and short decay to NOISE LEVEL to add a percussive attack to a sound. (Noise should be set to zero in the Mixer.)

Actually, any of the Pro 3's envelopes can be routed to any destination (or multiple destinations) using the modulation matrix. See "Modulation" on page 47 for more information.

Sustain: 0...127—Sets the sustain level of the envelope. It will stay at this level for as long as a note is held on the keyboard.

Release: 0...127—Sets the release time of the envelope. This controls how quickly the value transitions to zero after a note is released on the keyboard.

Amount: -127...127—Sets the amount of modulation from the envelope to the selected modulation destination. Higher amounts more dramatically affect the destination. This control is bipolar. Positive settings produce standard behavior. Negative settings invert the envelope.

Delay: 0...127—Sets a delay between the time the envelope is triggered (note on) and when the attack portion actually begins.

Loop: Off, On—When on, the Delay, Attack, and Decay segments of the envelope repeat. Sustain still affects the level at which the Decay segment ends, but instead of sustaining at a fixed level while a key is held down, Delay, Attack, and Decay loop until the key is released. (The Release segment begins when the key is released, just as it does when Repeat is off.)

Low Frequency Oscillators

The three LFOs are special-purpose oscillators that produce a frequency that is typically below the range of human hearing (although these can actually extend into the audio range if set to their maximum frequency). The LFOs are typically used for periodic modulation such as vibrato (periodic pitch modulation) and tremolo (periodic amplitude modulation). They can also be used as modulation sources for any of the many modulatable parameters in the Pro 3.

The LFOs produce a variety of waveshapes, including triangle, sawtooth, reverse sawtooth, square, and s&H (sample & hold/random). Though most often used for low-frequency modulation, the Pro 3 LFOs can actually function at speeds that extend into the audible range for extreme effects.

1 2 3 FREQUENCY AMOUNT - + W W N U S&H O O O O □ □ DESTINATIONSHAPE LFO

The Low Frequency Oscillators

Triangle and Sample & Hold waves are bipolar. That is, their waveshape is positive for half of their cycle and negative for the other half. In the case of the triangle wave, this makes it possible to generate a vibrato that goes alternately sharp and flat in equal amounts on either side of a center frequency. Random, also known as “sample and hold,” generates a series of random values, each held for the duration of one cycle.

The square wave, sawtooth, and reverse sawtooth generate only positive values. In the case of the square wave, this makes it possible to generate natural-sounding trills.

The LFOs can be free-running or synced to the Arpeggiator, Sequencer, or MIDI clock for tempo-synced effects such as filter sweeps, tremolo, and so on.

LFO Parameters (Front Panel)

Frequency: 0...150—Sets the frequency of the selected LFO from a slow .022Hz to a fast 500Hz. This is affected by the CLK SYNC (clock sync) parameter as explained below.

Amount: 0...127—Sets the amount of LFO modulation routed to the selected destination. Setting an amount here applies the selected modulation continuously. You can also use the modulation matrix to route an LFO to additional destinations and use a different modulation amount if you want.

Shape: Triangle, Sawtooth, Reverse Sawtooth, Square, S&H—This button sets the waveshape of the selected LFO.

Destination: Various—Routes the selected LFO to one of the many modulation destinations within the synthesizer. These appear in the display. You can also use the modulation matrix to route an LFO to additional destinations.

There are many ways to make creative use of the LFOs:

• Route the LFO to the COARSE FREQ parameter of the oscillators to create vibrato (TRIANGLE wave) or random pitches (S&H/RANDOM wave).
• Route the LFO's triangle wave to the filter's CUTOFF parameter and use a medium FREQ and AMOUNT setting to create a wah-wah effect, or use a slow FREQ setting and low AMOUNT setting to create subtle harmonic movement.
• Route the LFO's square wave to the amplifier's AMOUNT parameter and use a medium FREQ and AMOUNT setting to create a tremolo effect.
• Route an LFO to an oscillator's SHAPE parameter to make its timbre evolve. This can be particularly interesting when using Oscillator 3 wavetables.
• Route the LFO's triangle wave to the TIME parameter of the stereo delay and use a slow FREQ and low AMOUNT setting to create a chorus effect.

Any LFO can be routed to any destination (or multiple destinations) using the modulation matrix. See page 120 for a list of destinations.

Additional LFO Parameters (Display Menus)

Additional LFO parameters are accessible through the menus in the main display. To see these menus, adjust any of the controls in LFO portion of the front panel.

Sync: When on, the LFO synchronizes with the master clock, which controls the Arpeggiator, Sequencer, and certain effects.

Amount: Sets the amount of LFO modulation routed to the selected destination. Setting an amount here applies the selected modulation continuously. You can also use the modulation matrix to route an LFO to additional destinations and use a different modulation amount.

TAB 2 - LFO Control

Slew Rate Wave ResetPhase 0 SLEW RATE 0 PHASE WAVE RESET LFO Control F0 Shop Best

Slew Rate: 0...127—Slew adds a smoothing effect to a control parameter by affecting its rate of change. You can think of it as glide/portamento for control voltages. For example, if you apply a high SLEW RATE value to the LFO's pulse wave, its sharp-edges will be smoothed and it will become more like a sine wave. The same is true when applied to the s&H/RANDOM LFO waveshape: the abrupt changes will be smoothed.

Phase: 0...127—Use Phase to offset the LFO waveshape's start point. For Phase to have any noticeable effect, WAVE RESET must also be enabled for that LFO. If the LFO is free-running—that is, with WAVE RESET off—there is no fixed start point from which the phase can be offset. This is useful for modifying the shape of the chosen LFO waveshape.

Wave Reset: Off, On—When off, the LFO is free running. When on, the LFO is re-started each time a new note is played. WAVE RESET is set independently for each LFO. This is useful if you want to ensure that the full waveshape is applied each time you strike a key.

Destination: Routes the selected LFO to one of the many modulatable destinations within the synthesizer. You can also use the modulation matrix to route an LFO to additional destinations.

There is a shortcut for routing an LFO to a front-panel destination (provided that the destination is a valid destination). Simply hold down the selector button of the desired LFO or the LFO's DESTINATION button, then move the knob or control you want to use as a destination (the filter cutoff, for example). Set the amount using the LFO AMOUNT knobs. Be aware that not all front-panel controls can be used as a modulation destinations.

Modulation

Although the overall sonic character of the Pro 3 is determined by its oscillators and filters, much of its power to make truly unique sounds comes from creative use of modulation. Modulation is the process of routing one parameter (used as a control voltage) to another parameter in order to change the way the targeted parameter behaves.

The Modulation Matrix

The concept is simple:

1. Choose a source.

2. Choose a destination.

3. Set an amount. The amount can either be positive or negative.

You already understand and apply the concept of modulation whenever you use the filter envelope to control the filter's cutoff frequency. In this case, the modulation source is the filter envelope (or more precisely, any of its controls, such as attack, decay, sustain, or release). The modulation destination is the filter's CUTOFF frequency. The modulation amount is set with the Filter Envelope's AMOUNT knob.

There are 46 different modulation sources and 171 different destinations to choose from. (See page 119 for a complete list.) There are also 32 freely assignable modulation paths (mod slots 1-32) as well as 5 additional dedicated mod sources including LFO 1-3, and Auxiliary Envelope 1 and 2. This gives you a large number of sound-shaping options.

MODULATION SOURCE DESTINATION AMOUNT

The Modulation section

There are shortcuts for routing modulation to various front panel sources/destinations. Simply hold down the SOURCE button and move the control you want to use as a source (the Mod wheel, for example). Then hold down the DESTINATION button and move the control that you want to use as a destination (filter cutoff, for example). Set the amount with the AMOUNT knob while referring to the display. Be aware that not all front-panel controls can be used as a modulation sources/destinations.

Modulation Examples

Here are several modulation scenarios that illustrate how to use the modulation matrix. The examples provide step-by-step instructions for clarity. Some of these setups are built into the basic program, which you can recall from the GLOBAL menu.

To use the Mod wheel to add vibrato:

1. In the LFO section, set LFO 1 to TRIANGLE and set FREQUENCY to 75. Set DESTINATION to OSC ALL FREQ. Set AMOUNT to 0. (You will control the amount with the Mod wheel.)

2. In the MODULATION section, press the SOURCE button. Use SOFT KNOB 1 to scroll to Mod Slot 1 if it's not already displayed.

3. Use SOFT KNOB 2 to scroll through the various mod sources and choose MOD WHEEL (As a shortcut you can hold down the SOURCE button and move the Mod wheel.)

4. Use Soft KNOB 3 to set the amount to 30.

5. Use SOFT KNOB 4 to scroll through the various mod destinations and choose LFO1 AMT.

6. Hold down a note on the keyboard and turn the Mod wheel. You should hear vibrato.

Use PRESSURE as the modulation source instead of the Mod wheel in the previous example to add vibrato with key pressure/aftertouch.

To use the Touch slider to control the filter cutoff:

1. In the MODULATION section, press the SOURCE button. Use SOFT KNOB 1 to scroll to Mod Slot 1 if it's not already displayed.

2. Use SOFT KNOB 2 to scroll through the various mod sources and choose SLIDER.

3. Use SOFT KNOB 4 to scroll through the various mod destinations and choose CUTOFF.

4. Hold down a note on the keyboard (or press the HOLD button and play a note on the keyboard) and move a finger up and down the Touch slider.

5. Use SOFT KNOB 3 to set the amount to your preference. Higher AMOUNT settings cause the filter to open wider the farther up you move your finger along the Touch slider. A negative amount setting will close the filter farther up you move your finger along the Touch slider.

Use PRESSURE as the modulation source instead of the Touch slider in the previous example to open the filter (positive AMOUNT) or close the filter (negative AMOUNT) with pressure.

Other modulation ideas:

- To create the classic “attack pitch blip” effect in many synth brass sounds, choose a good three-oscillator synth brass sound then route Aux Envelope 1 to osc 2 COARSE FREQ and set Aux Envelope 1 to Attack: 0, Decay: 30, Sustain: 0, and Release: 0 with an amount of 18.

- Route an LFO to PAN to create an auto-panning effect. Panning width is controlled by the modulation amount. Panning speed is controlled by the LFO frequency. Add a second mod path to control the LFO speed with the Mod wheel for a controllable rotating speaker spin-up/spin-down effect. Add the rotating speaker effect as Effect 1 and set up a third mod path to control FX1 MIX with the Mod wheel for even better results.

- Route VELOCITY to DISTORTION to overdrive a synth lead sound the harder you play.

- Tune Oscillator 3 to a perfect 5th (7 semitones) and set its mixer level to 0. Then create a mod path to control Osc 3 LEVEL with the Mod wheel or Touch slider so you can add it to the mix in live performance. Finally, add DISTORTION to the sound and you can create a convincing “guitar-with-controllable-feedback” effect.

Effects

You can add two digital effects to any Pro 3 program. Not all sounds need effects to make them interesting, but adding a touch of delay or reverb can add a sense depth, just as adding chorus, flanging, or phasing can add movement. Effects settings are saved individually with each program.

If you enable SYNC for time-based effects such as the delays, their repeat rate is synchronized to the Arpeggiator, Sequencer, or MIDI clock for repeats that occur on the beat.

To use Effects:

1. Press the EFFECT 1 button to turn on effect 1.
2. Press Soft Button 2 (FX1 PARAMS) in the display to select effect 1 for editing.
3. Turn the EFFECT TYPE knob to choose an effect.
4. Turn the MIX knob to blend in a good amount of the processed signal. You'll want to be able to clearly hear the effect when you tweak its settings. You can dial it down afterward.
5. Use the PARAM 1, PARAM 2, and PARAM 3 knobs to adjust the effect's parameters to your taste. See "Effects Parameters" on page 52 for details on the adjustable parameters on each effect type.
6. Finally, adjust the MIX knob again to optimize the amount of the effect. Full left is completely dry. Full right is completely wet (a 100% processed signal).
7. To sync a delay to the Arpeggiator or Sequencer, enable its SYNC parameter and adjust the TIME parameter (Parameter 1) as needed.

Effects Parameters (Front Panel)

Effect 1: Turns effect 1 on or off.

Effect 2: Turns effect 2 on or off.

Effect Type: stereo delay, bbd delay, chorus, flanger, phaser, HP filter, ring mod, rotating speaker, super plate—Selects the effect type.

Show Effects: Shows the Effects menu in the display for editing. Pressing this button more than once toggles between the two effects in the display.

Mix: 0...127—Sets the balance between the processed (wet) signal and unprocessed (dry) signal. Full left is completely dry. Full right is completely wet.

Sync (in the main display): On, Off—When a delay effect is chosen, this enables syncing of the timed delay repeats (feedback) to the Arpeggiator, Sequencer, or MIDI clock. When SYNC is on, delay time has the following values:

Value Delay Time
Whole (1) 4 beats
Half dot (2D) 3 beats
Half (2) 2 beats
Quarter dot (4D) 1 1/2 beats
Quarter (4) 1 beat
Quarter triplet (4T) 1 1/3 beats
8th dot (8D) 3/4 of 1 beat
8th (8) 1/2 of 1 beat
8th triplet (8T) 1/3 of 1 beat
16th dot (16D) 3/8 of 1 beat
16th (16) 1/4 of 1 beat

Maximum delay time is approximately 1 second. The combination of longer synced delay times with slower tempos can result in delay times that would be greater than 1 second. When that happens, the delay time is divided by 2 until it no longer exceeds the 1 second limit. For example, if the BPM is set to 60 and Delay Time (Parameter 1) is set to Half, the expected delay time would be 2 seconds. The actual delay time will be 1 second (i.e. 2 seconds divided by 2).

Parameter 1: Variable, depending on the effect—This knob adjusts parameter 1 for the chosen effect. Each effect has three adjustable parameters, which differ depending on the effect.

Parameter 2: Variable, depending on the effect—This knob adjusts parameter 2 for the chosen effect. Each effect has three adjustable parameters, which differ depending on the effect.

Parameter 3: Variable, depending on the effect—This knob adjusts parameter 3 for the chosen effect. Each effect has three adjustable parameters, which differ depending on the effect.

Effect Type Param 1 Param 2 Param 3

To recreate a classic time-shifting effect on the stereo or BBD delay, try adjusting the delay time parameter in real time. You can also route an LFO or envelope to the delay's Time parameter using the modulation matrix.

Arpeggiator

The Arpeggiator allows you to hold a chord and the synthesizer will play a pattern based on the individual notes held. You can adjust the playback mode (up, down, up+down, random, assign.), the octave range (1, 2, or 3), the number of repeats per note, and the tempo. The Arpeggiator usually works best on sounds with a fast attack.

While you hold down a chord, pressing any additional notes will add those notes to the arpeggio. You can change chords and notes and the arpeggio will continue to play as long as at least one note is always held.

You can also use the HOLD feature with the Arpeggiator. When you enable HOLD, you can release the notes on the keyboard and the arpeggio will continue to play — with any additional notes that you play added to the arpeggio.

To prevent the Arpeggiator from adding new notes to an arpeggio when keys are continuously held (and instead start a new arpeggio each time you change notes), turn arp relatch on in the Arpeggiator. To do this, press the Arpeggiator's ON/OFF button and turn Soft Knob 3 to turn arp relatch on in the display.

Set the tempo of the Arpeggiator with the TAP TEMPO or BPM and DIVIDE controls. To use TAP TEMPO, tap this button 4 times to set the tempo. You can also sync the Arpeggiator to external MIDI clock, or even an external audio signal.

The Arpeggiator can run concurrently with the Sequencer for arpeggiated patterns with sequenced parameter automation. To do this, turn on the Arpeggiator and set the Sequencer mode to TRIGGER. The Sequencer will step with each Arpeggiator step. You can even record parameter changes during Arpeggiator playback by holding down the Sequencer's RECORD button and turning knobs to make parameter changes in real time. The parameter changes will be recorded and included in the sequence.

The Arpeggiator

To use the Arpeggiator:

1. Press the ARPEGGIATOR ON/OFF button to turn it on.
2. Hold down one or more notes on the keyboard. The Arpeggiator plays them according to the settings you've chosen.
3. To latch arpeggiation on (so that you don't have to continuously hold down notes) press the HOLD button.
4. In the display menu, adjust settings such as MODE, OCTAVE RANGE, REPEATS, and BPM.
5. To synchronize a delay effect to the Arpeggiator, enable Effect 1 or Effect 2, choose a delay, then turn on SYNC in the delay's parameter page in the display. Adjust the delay's TIME parameter as desired.

Arpeggiator "Momentary Sustain" Mode

The Pro 3 allows you to use the sustain pedal to turn the Arpeggiator's Hold function on and off and perform other Arpeggiator-related functions. To access this feature, use the FOOTSWITCH FUNCTION setting in the GLOBAL menu.

There are three modes to choose from:

- SUSTAIN - With the Arpeggiator running in this mode, pressing and holding the Sustain pedal sustains the notes, as the Sustain pedal normally would.

- ARP HOLD - With the Arpeggiator running in this mode, pressing the Sustain pedal once causes the Arpeggiator to hold the sequence (even when you release the notes on the keyboard). Pressing it again stops the Arpeggiator.

- ARP HOLD MOM - With the Arpeggiator running in this mode, pressing and holding the Sustain pedal causes the Arpeggiator to sustain (even when you release the notes on the keyboard) for as long as you hold down the pedal. Releasing the Sustain pedal stops the Arpeggiator.

To select the Arpeggiator's sustain pedal mode:

1. Press the GLOBAL button then use Soft Knob 1 to scroll to FOOTSWITCH FUNCTION.
2. Use Soft Knob 3 to select SUSTAIN, ARP HOLD, or ARP HOLD MOM, depending on your preference. Press the GLOBAL button again to exit the Global menu.

MIDI Note Output from the Arpeggiator

The Arpeggiator outputs MIDI note messages. Any notes that you hold on the keyboard will be arpeggiated according to the current settings of the Arpeggiator and output over MIDI as MIDI notes. You can use this feature to drive other MIDI-equipped devices such as synthesizers and drum machines. To access this feature, use the MIDI ARP NOTES setting in the GLOBAL menu.

To enable MIDI Note output from the Arpeggiator:

1. Press the GLOBAL button, then turn Soft Knob 1 to select MIDI ARP NOTES.
2. Turn Soft Knob 3 to select ON.

To control an external MIDI device:

1. Connect the MIDI or USB output of the Pro 3 to the MIDI or USB input of the external device, depending on which type of connection the external device requires.
2. On the Pro 3, press the GLOBAL button, then use Soft Knob 1 to select MIDI OUT SELECT.
3. Use the Soft Knob 3 knob to select MIDI, or USB, or MIDI+USB, depending on how your Pro 3 and external device are connected.
4. Press the GLOBAL button again to exit the Global menu.
5. On the external device, set the the MIDI Channel and MIDI Receive port to match the Pro 3.
6. Hold down a chord on the Pro 3 or start Sequencer playback. The external device should be triggered by the arpeggiated or sequenced notes.

Arpeggiator Parameters (Display Menus)

Arpeggiator parameters are accessible through the menus in the main display. To see these menus, adjust any of the controls in ARPEGGIATOR section of the front panel.

Front Panel Arpeggiator On/Off Button—This button turns the Arpeggiator on and off.

Arp Mode Arp RelatchOctave Range Repeats Up+Down 1 Oct 0 OCTAVE RANGEARP LOWERELATCH REPEATS Seq ModesBI Arp

Arp Mode: Sets the order in which notes play when the Arpeggiator is on. See the table.

Arp Mode Behavior
Up Plays from	lowest to highest note
Down Plays from	highest to lowest note
Up + Down Plays	from lowest to highest and back to lowest
Random Plays	notes in random order
Assign	Plays notes in the order the keys were pressed

Octave Range: 1, 2, 3 —Set to 1, only the held notes are arpeggiated. Set to 2, the held notes and the notes one octave above them arpeggiate. Set to 3, the held notes and the notes one and two octaves above them arpeggiate.

Relatch: Off, On—Works in conjunction with HOLD. When HOLD and the Arpeggiator are on, and ARP RELATCH is off, played notes are held on and arpeggiated, with additional played notes added to the held notes and the arpeggio. When ARP RELATCH is on, played notes are held on and arpeggiated, but additional played notes will restart the arpeggio with the new notes.

Repeats: 1, 2, 3 —Set to 1, each note in the arpeggio plays once. Set to 2, each note in the arpeggio plays twice. Set to 3, each note in the arpeggio plays three times.

Clock Parameters

BPM: 30...250—Sets the tempo for the Arpeggiator in BPM (beats per minute). The TAP TEMPO LED flashes at the BPM rate. When SYNC is enabled on the low-frequency oscillator, or enabled in the Effects section, the BPM rate affects the LFO frequency and/or delay effect. When syncing to an external MIDI clock source, the BPM setting has no effect.

Divide—Selects a basic note value relative to the BPM. See the table below:

Name Tempo Timing Division
Half BPM/2 Half note
Quarter BPM Quarter note
8th BPM x 2 Eighth note
8 Trip BPM x 3 Eighth note triplets
16th BPM x 4 Sixteenth note
16 Trip BPM x 6 Sixteenth note triplets
32nd BPM x 8 Thirty-second note
32 Trip BPM x 12 Thirty-second note triplets
64th BPM x 16 Sixty-fourth note

Tap Tempo—Pressing the TAP TEMPO button 4 times sets the tempo. The LED flashes at the BPM rate you set.

Sequencer

The original Sequencers in modular synthesizers were used as a modulation source. They produced a series of control voltage events at timed intervals that could be used to change the value of a synth parameter in discrete steps. Sequences could be routed to oscillator frequency to produce a series of pitched notes, to filter frequency to produce stepped filtering effects, and so on.

The Pro 3 Sequencer is like its analog precursors but more powerful. The Pro 3 Sequencer has 16 tracks and 4 linkable 16-step phrases (A,B,C,D) for creating repeating patterns of notes, or 3-note chords in paraphonic mode.

You can create sequences of variable length and add rests, ties, per-step ratcheting, and adjust duration, and velocity. Each Sequencer track can be routed to a different modulation destination using the mod matrix, and each step in a sequence can be set to a different value to modulate that destination.

All factory programs have a sequence associated with them. Recall a program and press the Sequencer's PLAY button to hear its associated sequence.

Normal, Gated, and Trigger Modes

The Sequencer has three modes of operation that control how sequence playback is started: Normal, Gated, and Trigger.

Normal — In NORMAL mode, sequence playback starts when you press the PLAY button.

Gated — In GATED mode, sequence playback starts and continues as long as you hold down a key on the keyboard.

Trigger — In TRIGGER mode, sequence playback is initiated by a specific type of trigger:

• Keyboard trigger. Repeatedly pressing a key on keyboard advances the sequence one step each time you press a key.
• The Arpeggiator. Selecting TRIGGER mode, then turning on the Arpeggiator and holding down a chord on the keyboard runs the sequence while notes are held. In this case, sequenced Note tracks are ignored and only parameter automation tracks are played. This is useful for adding sequenced filter sweeps or other modulation to an arpeggio.
• External input trigger. External input triggers include an external audio input signal, MIDI, or a control voltage input.

Programming the Sequencer

By default, Track 1 of the Sequencer controls oscillator frequency, meaning that it's hard-wired for recording notes. Beyond that, any Sequencer track can be routed to any modulation destination. A typical scenario might have other tracks routed to filter cutoff, filter resonance, noise level for drum-like accents, and so on.

To program a monophonic note sequence:

1. Select a program with a relatively sharp attack and short release.
2. Press the RECORD button. Phrase A is selected by default.
3. Play a sequence of notes on the keyboard. The numbered step LEDs indicate where you are in the sequence. A white LED indicates the current step. A red LED indicates a note has been recorded on that step.
4. If you make a mistake, toggle the RECORD button off, then on again, and replay the notes correctly.
5. If you want to record fewer than 16 steps, play only the notes you want. If you play more than 16 notes/steps, the Sequencer will ignore the additional notes.
6. When you've finished, press the PLAY button to hear your sequence. A white LED indicates the current step. A red LED indicates a note has been recorded on that step.
7. Use the BPM, DIVIDE, or TAP TEMPO controls to adjust Sequencer playback speed.
8. To change playback direction of the sequence, press one of the DIRECTION buttons (REV, FWD/REV, RANDOM).
9. To stop playback, press the PLAY button again.
10. To save the sequence, save the program by pressing the WRITE button twice.

A quick way to edit a step when playback is stopped is to press and hold the step LED for the desired step. You can then play a note and the Sequencer will update the sequence to use that note and the velocity at which you played it. You can also edit any other parameter for that step while you're at that step location.

To transpose a sequence up or down during playback:

1. Press the PLAY button to hear the sequence.
2. Press a note on the keyboard above or below middle C. The sequence is transposed to that key. (Middle C plays the sequence as recorded.) For greater range, use the Transpose Up or Transpose Down buttons.
3. During playback, if you want to restart a sequence from step 1, press the RESET button.

To record over an existing note sequence:

1. Press the RECORD button.
2. Play different notes on the keyboard. The numbered step LEDs indicate which step you're on.
3. When you're done, press PLAY to listen to the new sequence.
4. To resave the sequence, save the program by pressing the WRITE button twice.

Recording Phrases/Sequences A,B,C, or D.

The Pro 3 can record up to four independent phrases/sequences per program. You can select among these by pressing the A,B,C,or D SEQUENCE buttons on the front panel. During real-time playback you can switch between these on the fly. (You can also chain them together for sequences longer than 16 steps. See “Creating An Extended Sequence” on page 66 for more details.)

To record Sequence B,C, or D:

1. Press SEQUENCE button B,C, or D.
2. Press the RECORD button and play a sequence of notes on the keyboard.
3. When you've finished, press the PLAY button to hear your sequence.

As noted above, you can switch between sequences A,B,C, and D on the fly during playback by simply pressing the button of the sequence you want to play. You can also chain them together for sequences longer than 16 steps. See “Creating An Extended Sequence” on page 66 for more details.

Sequencing Parameter Changes in Real-Time

The Sequencer makes it easy to record parameter changes in real-time as part of any of the four phrases/sequences, A,B,C, and D. To do this, start playback, then hold down the Sequencer's RECORD button and adjust front-panel controls such as filter cutoff, noise level, envelope settings, or other parameters.

As the sequence plays, the Sequencer records the changes to the parameter and incorporates them into the sequence. Each parameter you adjust is assigned to one of the available Sequencer tracks, 4-16. (Tracks 1-3 are reserved for note-related functions, but tracks 4-16 can be freely assigned.)

Be aware of where and when the sequence loops back around to its beginning since the Sequencer continues to record (and possibly overwrite) any parameter changes you make as it repeats.

To sequence parameter changes in real-time:

1. Start playback of an existing sequence by pressing the PLAY button.
2. As the sequence plays, hold down the RECORD button and adjust a parameter (such as filter cutoff) in real-time. Recording loops around with the sequence, continuously updating the changes you make.
3. As long as you continue to hold down the RECORD button during play-back you can continue to adjust that parameter or additional parameters. Each parameter is assigned to one of the available tracks, 4-16.

Copying a Sequence from One Track to Another

Sometimes it's useful to copy a sequence from one track to another, particularly when tracks are used for parameter modulation.

To copy one track to another:

1. Press the SEQUENCE button to select the sequence you want (A, B, C, or D).
2. Press and hold the TRACK SEL button and press Soft Button 2 (COPY TRACK).
3. Continue to hold down the TRACK SEL button and press the step LED with the same number as the track you want to copy (step 1 = track 1, etc.).
4. Continue to hold down the TRACK SEL button, then press the step LED with the same number as the track you want to paste the copied track onto.

Copying and Pasting an Entire Sequence

You can also copy and paste an entire sequence between sequences A,B,C, and D. This duplicates all data on all tracks.

To copy and paste an entire sequence:

1. Press and hold the TRACK SEL button and press Soft Button 2 (COPY TRACK).
2. Continue to hold down the TRACK SEL button and press the A, B, C, or D sequence button, depending on which one you want to copy.
3. Continue to hold down the TRACK SEL button, then press the A, B, C, or D sequence button, depending on which you want to paste the copied track onto.

The Cue Program and Seq Lock features provide a simple way to copy a sequence from one program to another. See “Cue Program” on page 79 for more details.

Muting a Sequence Track

Sometimes it's useful to mute a track to ignore the sequence data recorded on it.

To mute a Sequencer track:

1. Press the SEQUENCE button to select the sequence you want (A, B, C, or D).
2. Press and hold the TRACK SEL button and press the step LED with the same number as the track you want to mute (step 1 = track 1, etc.).
3. Press Soft Button 4 (MUTE) to set it to ON. The track is muted.
4. To toggle off muting, repeat steps 2 and 3.

Creating An Extended Sequence

If want to create a sequence that's longer than 16 notes/steps, you can do so by putting the Sequencer in extended mode. This chains the individual phrases/sequences A, B, C, D together. Since each of the four individual phrases/sequences has a maximum of 16 steps, you can create a sequence of up to 64 steps in total.

Set this parameter to "Extended" to create a sequence longer than 16 steps Seq Mode Seq Length Extended 32 Steps SEQ LENGTHSEQ MODE Seq Modes PM ArpSeq Para

Enabling extended sequence mode

To program an extended monophonic note sequence:

1. Show the Sequencer mode menu by pressing the ARPEGGIATOR button. If necessary, press the button again to turn off the Arpeggiator
2. Press Soft Button 3 (SEQ MODES) to select the SEQUENCER MODE menu.
3. Turn Soft Knob 1 and choose EXTENDED.
4. Turn Soft Knob 2 and choose the length of the sequence. The maximum length is 64 steps.
5. Press the RECORD button and play the desired notes on the keyboard. The numbered step LEDs indicate your current step location. When you cross over into the next 16-step sequence (A,B,C,D) the appropriate LED will light up.
6. When you're done, press PLAY to listen to the sequence.
7. To save the sequence, save the program by pressing the WRITE button twice.

Paraphonic Sequencing

The Pro 3 can play and sequence 3-note chords when operating in paraphonic mode. In this mode, track 1 is routed to Oscillator 1, track 2 to Oscillator 2, and track 3 to Oscillator 3.

Play Source Sync to Trk1 Restart Para Seq On OnKeyboard On SYNC TO TRACK 1PLAY SOBSEART PARA SEQ BPM Seq Params Eq Modes Arp Press the Paraphonic button on the front panel to enable this parameter. Then use soft knob 4 to select On.

Enabling paraphonic mode

To record a paraphonic sequence:

1. Set all three oscillators to the same level in the mixer. You will probably want to set them to the same octave as well.
2. Press the PARAPHONIC button to enable paraphonic mode. The Sequencer menu appears in the display.
3. Press Soft Button 2 to select the SEQ PARAMS menu.
4. Turn Soft Knob 4 (PARA SEQ) and choose ON. Paraphonic sequencing is now enabled.
5. Press the RECORD button and play a series of notes and chords on the keyboard. You can play up to 3-note chords. The numbered step LEDs indicate your current step location.
6. When you're done inputting notes, press PLAY. Your sequence plays back. To stop playback, press PLAY again.
7. To save the sequence, save the program by pressing the WRITE button twice.

Adding Rests, Ties, and Velocity

When recording note sequences using the keyboard, the Sequencer assigns each note that you play (along with its velocity) to successive steps in the sequence. However, you may want to add rests, ties, and additional velocity changes for greater rhythmic variation.

Adding Rests

Rests turn off notes. You can add rests as you record a sequence in real time, or you can add them after you've finished recording.

To add rests in real time as you record:

1. Press the RECORD button and play a series of notes.
2. When you reach a step where you want to add a rest, press that step LED/button. The step becomes a rest.
3. If you want to add several rests in a row, press the step LED/button where you want the rest to end.

4. Continue playing notes as desired to complete the sequence.

5. When you're done, press PLAY. Your sequence plays back. To stop play-back, press PLAY again.

6. To resave the sequence, save the program by pressing the WRITE button twice.

A quick way to add a rest to an already-recorded sequence is to toggle off the front-panel LED/button for that step. The step/button can be toggled on again if you want.

An unlit LED indicates a rest notes/vel duration ratchet cutoff assign 1 assign 2 assign 3 assign 4 SLEWSEQ LOCKA TRAC

Unlit LEDs indicate rests (or steps with no notes recorded)

To add rests to an existing sequence using the sequence editor:

1. To show the track in the display, hold down the TRACK SEL button and press the step LED with the same number as the track you want to edit (step 1 = track 1, and so on).

2. Release the TRACK SEL button. The track appears in the display.

3. On the front panel, toggle off the LEDs for the steps that you want to rest. (The step can be toggled on again if you want.) The rest appears as an asterisk (*) in the display.

4. Repeat for any additional steps/rests.

5. To listen to the sequence, press PLAY.

Adding Ties

Ties allow you to increase the duration of a note in a sequence (i.e. the number of steps that it's held). You can add ties as you record a sequence in real time, or you can add them after you've finished recording

To add ties in real time as you record:

1. Press the RECORD button and play a series of notes.
2. When you reach a step where you want to add a tie, play the note on the keyboard, then press and hold that step LED/button (the LED will be red).
3. With that step LED/button still held down, press the step LED/button where you want the tie to end. That series of steps is now tied and the note sustain for that duration.
4. Release the buttons.
5. Continue playing notes as desired to complete the sequence.
6. When you're done, press PLAY. Your sequence plays back. To stop play-back, press PLAY again.

LEDs are dimmed on steps that are tied.

Envelope setting and the Sequencer's DURATION parameter may affect how tied sustain.

To add ties to an existing sequence:

1. To show the track in the display, hold down the TRACK SEL button and press the step LED with the same number as the track you want to edit (step 1 = track 1, and so on).
2. Release the TRACK SEL button. The track appears in the display.
3. On the front panel, press and continue to hold the LED button for the step where the tie will start.
4. Press the LED button for the step where the tie will end.
5. Release the buttons.
6. To create additional ties, repeat steps 3-5.

Editing Velocity

When you use the keyboard to record note sequences in real time, the Sequencer records note velocity along with the note values. The sequence editor allows you to edit these values.

To edit velocity on an existing sequence:

1. To show the notes track in the display, hold down the TRACK SEL button and press step LED 1 (NOTES/VEL). Note that if the sequence is paraphonic, tracks 2 and 3 are also note tracks.

2. Release the TRACK SEL button. The notes track appears in the display.

3. Press Soft Button 1 (VELOCITY) to display the velocity parameter for the track.

4. Turn Soft Knob 1 (STEP) to scroll to the desired step.

5. Turn Soft Knob 4 (vel) to edit the velocity value of the selected step.

6. Repeat steps 4 and 5 as desired.

Velocity is only available for editing on note tracks or tracks that have (MIDI)

Out 1 or Out 2 as their destination.

If you have a Sequencer track assigned to a MIDI channel output and it is only ing MIDI note-off messages, check the value of the Velocity parameter for each step.

A velocity greater than zero must be set for a MIDI note-on message to be sent. If the velocity for a given step is set to zero, only a MIDI note-off message will be sent for that step.

Editing Duration

You can use the Sequencer editor to edit the gate duration of notes after you've recorded them. This is useful for creating staccato or legato effects.

To edit duration on an existing sequence:

1. To show the notes track in the display, hold down the TRACK SEL button and press step LED 1 (NOTES/VEL). Note that if the sequence is paraphonic, tracks 2 and 3 are also note tracks.
2. Release the TRACK SEL button. The track appears in the display.
3. Press Soft Button 2 (DURATION) to display the duration parameter for the track.
4. Turn Soft Knob 1 (STEP) to scroll to the desired step.
5. Turn Soft Knob 4 (DUR) to edit the duration value of the selected step. Lower values create staccato effects. Higher values create legato effects.
6. Repeat steps 4 and 5 as desired.

Adding Ratcheting

Ratcheting adds tuplet effects by repeating a note trigger multiple times on the same step. You can choose from 1 to 8 repetitions per step. You may need to adjust envelope settings and a step's DURATION parameter to hear each repetition, depending on the sequence.

To add ratcheting to an existing sequence:

1. To show the notes track in the display, hold down the TRACK SEL button and press step LED 1 (NOTES/VEL). Note that if the sequence is paraphonic, tracks 2 and 3 are also note tracks.
2. Release the TRACK SEL button. The track appears in the display.
3. Press Soft Button 3 (RATCHET) to display the ratchet parameter.
4. Turn Soft Knob 1 (STEP) to scroll to the desired step.
5. Turn Soft Knob 4 (RCHT) to edit the ratchet value of the selected step.
6. Repeat steps 4 and 5 as desired.

Editing Other Elements of a Sequence

You can edit other aspects of a sequence as well, including note values and per-step modulation amounts for any tracks used to modulate synth parameters such as filter cutoff, and so on. This is convenient for fixing mistakes, modifying a sequence, or adding and refining elements of a sequence.

To use the sequence editor:

1. Press the SEQUENCE button to select the sequence you want to edit: A, B, C, or D.
2. To show the desired track in the sequence editor, hold down the TRACK SEL button and press the step LED with the same number as the track you want to edit.
3. Release the TRACK SEL button. The track appears in the display.

To edit notes:

1. Make sure track 1 (INITNOTE) is displayed. Then use Soft Knob 1 (STEP) to scroll to the step you want to edit.
2. Use Soft Knob 3 (NOTE) to change the note (C0 - G10).
3. To re-save the sequence, save the program by pressing the WRITE button twice.

To edit a note's velocity:

1. Make sure track 1 (INITNOTE) is displayed. Then use Soft Knob 1 (STEP) to scroll to the step you want to edit.
2. Press Soft Button 1 to active the velocity tab, then turn Soft Knob 4 (VEL) to enter a velocity value, 1-127. Turning the knob fully counterclockwise sets the step to REST.
3. To re-save the sequence, save the program by pressing the WRITE button twice.

A quick way to edit a step when playback is stopped is to press and hold the step LED for the desired step. You can then edit any parameter for that step while you're at that step location.

To edit a track used for modulation:

1. Press the SEQUENCE button to select the sequence you want to edit: A, B, C, or D.
2. To show the desired track in the display, hold down the TRACK SEL button and press the step LED with the same number as the track you want to edit.
3. Use Soft Knob 1 (STEP) to scroll to the step you want to edit.
4. Turn Soft Knob 3 (VAL) to enter a value, 1-127. Most values range from -127 to +127.
5. To save the sequence, save the program by pressing the WRITE button twice.

Setting or Changing the Destination of a Track

Each of the four sequences, A,B,C, and D have 16 tracks. Tracks 1-3 are reserved for note-related functions. Tracks 4-16 can be freely assigned.

To set or change the destination of a sequence track:

1. Show the desired sequence and track in the display by pressing the SEQUENCE button to select the sequence you want (A, B, C, or D) then holding down the TRACK SEL button and press the step LED with the corresponding track number you want to edit.
2. Press and hold the TRACK SEL button and turn Soft Knob 4 to scroll though a list of destinations. Remember that tracks 1-3 are reserved for note-related functions. Tracks 4-16 can be freely assigned.

A quick way to set the destination of a Sequencer track is to hold down the TRACK SELECT button and turn the front-panel knob for the parameter you want to route to that track.

Recording Additional Sequencer Tracks for Modulation

Tracks 4-16 can be freely assigned to any modulation destination. You can either start the Sequencer running and record the modulation values in real time by turning parameter knobs (in which case the Sequencer automatically assigns a track to the edited parameter) or you can input values step by step with the Sequencer stopped.

Here's how to sequence filter cutoff modulation step-by-step.

To modulate filter cutoff frequency using Sequencer Track 4:

1. Press and hold the TRACK SEL button then press Sequencer step LED 4. (Alternatively, turn Soft Knob 1 (SELECT TRACK) to select track 4.)
2. While continuing to hold down the TRACK SELECT button, turn Soft Knob 4 (DEST) to select CUTOFF.
3. Release the TRACK SELECT button.
4. Turn Soft Knob 1 to go to the desired step in the sequence
5. Turn Soft Knob 3 (VAL) to set a value.
6. Repeat steps 4 and 5 for each step in the sequence until finished.
7. To listen to the sequence, press PLAY.

If the length of track 1 (notes) is longer or shorter than the modulation tracks in a sequence, you can make all tracks restart to step 1 when track 1 plays step 1 by enabling SYNC TO TRACK 1 in the SEQ PARAMS menu (pres the ARPEGGIATOR button to display this menu).

Using Slew

Slew creates a smooth transition between successive, discrete control voltage levels. You can use slew to create glide effects between note values, a smooth filter cutoff sweep, and so on, depending on the parameter being sequenced.

To add slew to a sequence track:

1. Show the desired sequence and track in the display by pressing the SEQUENCE button to select the sequence you want (A, B, C, or D) then holding down the TRACK SEL button and press the step LED with the corresponding track number you want to edit.
2. Press the SLEW button. A preset amount of slew is added to the track.
3. To hear the effect, press PLAY to start the sequence.

Turning off the Sequencer's "Notes" Track

By design, Sequencer track 1 always controls oscillator frequency, meaning that it is effectively hard-wired for recording notes. However, you may want to use the Sequencer to control other parameters without having it trigger notes. By doing so, you can freely play notes on the keyboard while the Sequencer controls other non-note parameters such as filter cutoff, effect amount, oscillator shape mod, and so on.

To turn off Notes on the Sequencer:

1. Create a sequence with parameter automation.
2. Press and hold the front panel TRACK SEL button. Track 1 should be displayed by default. If not, continue holding down the TRACK SEL button and press the STEP 1 button/LED.
3. Continue to hold down the TRACK SELECT button press Soft Button 3 (NOTES) to set it to OFF.
4. Press the front panel MODE button and select GATED.
5. Play a series of notes on the keyboard. You'll hear the sequenced parameters change as you play the notes.

Sequencer Parameters (Front Panel)

Track Select: Pressing the button displays the sequence editor. Pressing and holding this button displays various commands for setting track destination, copying a sequence, turning notes on or off, and muting a track. Pressing and holding this button and pressing a step LED selects the corresponding track number and displays it in the sequence editor.

Sequence: A, B, C, D—These buttons select the active sequence.

Record: On, Off—This button turns sequence recording on and off.

Play: On, Off—This button starts and stops sequence playback.

Mode: Normal, Gated, Trigger—This button selects the playback mode. See “Normal, Gated, and Trigger Modes” on page 60 for more details.

Direction: fwd, rev, fwd/rev, random—This button sets the direction of sequence playback.

Reset: Pressing this button switch restarts sequence playback at step 1.

Seq Lock: On, Off—Enabling SEQ LOCK switch keeps the current sequence active while you change programs. In this way you can continue to run the same sequence while recalling different sound programs. If you save a program while using Seq Lock, it will save the sequence to that program and overwrite an existing sequence on that program.

Slew: On, Off—Turning on SLEW creates a smooth transition between the successive, discrete control voltage levels on each sequence step. Use slew to create glide effects between note values, a smooth filter cutoff sweep, and so on, depending on the parameter being sequenced. You can enable Slew individually for each track.

Tap Tempo: 30...250—Tap this button two or more times to quickly set the tempo for the Sequencer and Arpeggiator. The LED flashes at the BPM rate you set. For best results, tap the button 4 times.

BPM: 30...250—Sets the tempo for the Sequencer and Arpeggiator in BPM (beats per minute). When Sync is turned on for an LFO or Delay, the BPM rate affects its LFO frequency or delay time. When syncing to an external MIDI clock source, the BPM setting has no effect.

Divide: Sets the note value for each Sequencer/Arpeggiator step relative to the BPM. DIVIDE works with both internal and external clock sources. The following table lists the DIVIDE values.

Display Tempo Timing Division
Half BPM/2 Half note
Quarter BPM Quarter note
8th BPM x 2 Eighth note
8 Trip BPM x 3 Eighth note triplets
16th BPM x 4 Sixteenth note
16th Trip BPM x 6 Sixteenth note triplets
32nd BPM x 8 Thirty-second note
64th BPM x 16 Sixty-fourth note

Swing: 50%...75%—Adds a variable amount of shuffle-like feel to the master tempo. The greater the amount, the more obvious the effect.

Additional Sequencer Parameters (Display Menus)

Additional Sequencer parameters are found in the menus in the main display. To see these, press the RECORD button on the front panel.

The Sequencer Parameters menu

Play Source: Keyboard, Ext In, CV 1, CV 2, CV3, CV4—Selects how the Sequencer is triggered. When set to KEYBOARD, pressing a key on the keyboard control playback. When set to EXT IN, an audio signal connected to the AUDIO IN jack on the back of the Pro 3 will control playback. When set to CV 1, CV2, CV 3, or CV 4, playback is controlled by a control voltage signal connected to the matching control voltage input jack on the back of the Pro 3.

Sync to Track 1: On, Off—When on, restarts all tracks to step 1 when track 1 plays step 1. When off, all tracks play for their respective step lengths.

Restart: On, Off—When the Sequencer is in GATED mode, turning this parameter on restarts the sequence from step one each time you play a note on the keyboard. If this parameter is off, each time you play on a note on the keyboard, the sequence will begin from the most recent point in the sequence.

Para Seq: On, Off—Enables paraphonic sequencing. You can play chords of up to three notes and the Sequencer will record the individual notes to track 1, track 2, and track 3 respectively. Each of these tracks controls the pitch of one of the three oscillators. Paraphonic mode must must be on for this parameter to be available. (Press the front panel PARAPHONIC button.)

Cue Program

Cue Program provides a way to seamlessly switch to another program while the Sequencer continues to play the active sequence. The program will change in perfect sync with the last step of the sequence. The sequence then continues to play using the new, cued program. This also provides a simple way to copy a sequence from one program to another if you resave the cued program once the program and sequence become active.

To use Cue Program:

1. Start Sequencer playback.
2. Press and hold the CUE PROGRAM button. The bank/ program screen appears.
3. While you continue to hold CUE PROGRAM, use the BANK and PROGRAM knobs to select the program you wish to transition to.
4. Release the CUE PROGRAM button.
5. When track 1 of the Sequencer reaches its final step, the cued program will load and and the sequence will continue to play seamlessly.
6. If you want to copy the sequence to the cued program (and overwrite its original sequence) press the WRITE button twice.

Tuned Feedback

Tuned feedback is a method of processing audio using a delay line with tunable feedback. By varying the AMOUNT and TUNING parameters you can use it to create a variety of effects, some subtle, and some industrial-grade nasty, especially if you turn on GRUNGE.

TUNED FEEDBACK GRUNGE AMOUNT TUNING

The Tuned Feedback controls

Using Tuned Feedback to Perform "Karplus-Srong" Synthesis

You can also use Tuned Feedback as a tone generator. In classic Karplus-Strong synthesis, a short excitation waveform (white noise) is generated and fed back into a delay line. The output of the delay line is fed into the filter. The filter characteristics determine the harmonic structure of the decaying tone.

To use Tuned Feedback for Karplus-Strong synthesis:

1. In the Mixer, set all oscillator levels to zero.
2. Set the DESTINATION of Aux Envelope 1 to NOISE.
3. Set the AMOUNT of Aux Envelope 1 to 127.
4. Set the AUX ENVELOPE 1 ADSR values to the following: ATTACK: 0, DECAY: 45, SUSTAIN: 0, RELEASE: 16.

5. Set the Feedback AMOUNT parameter to 66.

6. Set the Feedback TUNING parameter to 12

7. Set the Filter Envelope's ATTACK and DECAY parameters to shape the envelope of the generated sound.
8. Experiment with the Feedback AMOUNT parameter and the ADSR parameters of Aux Envelope 1 to shape the harmonic content of the generated sound.

Feedback Parameters

Amount: -127...+127—Sets the level of feedback. As the amount goes up, the feedback will eventually oscillate at the frequency set with the tuning parameter. Medium levels of feedback add depth and movement to the sound.

Tuning: 0...48—Sets the base frequency of the feedback loop. It steps in semitones from C0 to C4 (0-48) for a four octave range. The exact frequency is influenced by factors such as filter cutoff frequency and the number of poles in the filter, which can drive it slightly sharp or flat.

Grunge: On, Off—When on, this enables extreme feedback at higher levels. It has no effect at lower levels of feedback.

Master Volume/Program Volume

The master output level of the Pro 3 is controlled by the front-panel MASTER VOLUME knob. In addition, the volume of an individual program can be set with the VOLUME parameter in the VCA menu. This is useful for ensuring that your sounds have roughly the same volume from program to program.

Volume 127 VOLUME VCA ADSR VA Env Am

Setting Program Volume in the Amp Envelope menu

To set the volume of an individual program:

1. Choose a program.
2. Move any of the AMP ENVELOPE controls on the front panel.
3. In the display menu, press Soft Button 1.
4. Turn Soft Knob 1 (VOLUME) to adjust the volume level as desired.
5. Press the WRITE button twice to save the program.

MIDI volume can also influence the overall volume of the Pro 3 if you are controlling it from an external MIDI source.

Transpose

The UP and DOWN buttons in the TRANSPOSE section transpose the keyboard up or down in octaves. The LED indicates the current keyboard transposition state. Transposing the keyboard also changes the MIDI note numbers of the keys so that MIDI notes sent are also transposed. Transpose settings are global and are not saved with individual programs.

-2 -1 0 +1 +2 Down Up TRANSPOSE

The Transpose controls

Hold

When HOLD is on, any notes played will continue to play until HOLD is turned off. When used in conjunction with the Arpeggiator, notes are latched on. If HOLD is on and at least one key continuously held down, any new notes played are added to the arpeggio.

The Hold button

Glide

Glide causes the pitch of a note to glide up or down from the pitch of the previously played note. Glide is turned on and off using the GLIDE switch, but the RATE must also be set. If the GLIDE button is on, but RATE is set to 0, glide has no effect. Glide can be set individually for each oscillator.

The Glide button

To use Glide:

1. Press the GLIDE button to turn Glide on.

2. Play a series of notes up and down the keyboard while you turn the GLIDE AMOUNT knob to adjust the amount of glide.

Glide Modes

There are four modes that determine how glide behaves:

Fixed Rate: The time to transition between notes varies with the interval between the notes; the greater the interval, the longer the transition time. The glide rate is fixed. This is the default glide mode.

Fixed Rate A: The same as Fixed Rate, but glide is only applied when playing legato. That is, glide only occurs when a note is held until the next note is played. This effectively allows glide to be turned on and off from the keyboard.

Fixed Time: Glide is set to a fixed time, regardless of the interval between notes.

Fixed Time A: The same as Fixed Time, but glide only occurs when playing legato.

To select a Glide Mode:

1. Press the GLIDE button.

2. In the display menu, use Soft Knob 1 to choose the desired Glide Mode.

3. Play a series of notes up and down the keyboard to hear the effect.

Pitch and Mod Wheels

The Pro 3 has a spring-loaded Pitch wheel and a Mod wheel. You can use these controls to enhance live performance by bending notes and adding modulation in real time as you play.

Two identical mechanical component diagrams labeled 'PITCH MOD', showing internal structure without any text or symbols.

The Pitch and Modulation wheels

Pitch Wheel

You can set a range in semitones for the Pitch wheel, depending on your playing preference. The upward range is 12 semitones (1 octave). The downward range is 24 semitones (2 octaves). Many musicians use a range of 2 semitones (a whole step) since this is the bend range of many acoustic instruments. For guitar whammy bar effects, you many wish to set a wider range.

To set the pitch bend range:

1. Press the MISC PARAMS button and press Soft Button 3 (PITCH WHEEL). Button 3
2. Use Soft Knob 1 (RANGE UP) to set the range in semitones of the upward bend.
3. Use Soft Knob 2 (RANGE DOWN) to set the range in semitones of the downward bend.
4. Hold a note and move the Pitch wheel to hear the effect.

Modulation Wheel

The Mod wheel controls the amount of modulation for any program that uses it as a modulation source. This allows you to “perform” modulation in real time by moving the wheel. This is a great way to add expressiveness to a sound or performance by using it to control vibrato, filter effects, and potentially a lot more.

To choose a modulation destination for the Mod wheel:

1. In the MODULATION section, press the SOURCE button. Use Soft Knob 1 to scroll to Mod Slot 1 if it's not already displayed.
2. Use Soft Knob 2 to scroll through the various mod sources and choose MOD WHEEL.
3. Use the Soft Knob 4 to scroll through the various mod destinations and choose a parameter (such as CUTOFF).
4. Hold down a note on the keyboard (or press the HOLD button and play a note on the keyboard) and turn the Mod wheel.
5. Use the Soft Knob 3 to set the modulation amount to your preference. Higher AMOUNT settings add greater modulation the further you push the Mod wheel. A negative amount setting will apply modulation in the negative direction.

As a shortcut, you can hold down the SOURCE button and move the Mod wheel to quickly assign this modulation path.

Touch slider

The Pro 3 has a position-sensitive Touch slider. Like the Pitch and Mod wheels, you can use this slider to enhance live performance by adding modulation in real time as you play.

The slider serves as a modulation source, the value of which is determined by finger position. The Touch slider appears in the modulation matrix as SLIDER. (See page 120 for a list of mod destinations.)

Normally, the slider affects the assigned modulation destinations only while it's being touched. But when LATCH is on, the Touch slider holds the value from the position at which it was last touched.

Latch TOUCH

The Touch slider

Use the mod matrix to assign modulation destinations to the slider. You can route multiple modulation destinations to the slider. To display the modulation matrix, press the SOURCE or DESTINATION buttons in the Modulation section. Modulation slots and routings appear in the display.

			DestinationEdit Mod 1 Source Amount
Mod 1	Slider	60	Cutoff
Mod 2	LFO 2t	35	Osc1 Shape
Mod 3	Aftertouch	25	Drive
Mod 4	Mod Wheel	80	LFO1 Amt
	Sort Source	Sort Dest

To assign the slider to a modulation destination:

1. On the front panel MODULATION section, press and hold the SOURCE button.
2. Touch the slider. The mod matrix appears in the display and SLIDER is assigned to an available modulation slot.
3. Turn Soft Knob 4 (DESTINATION) to choose a modulation destination.
4. Turn Soft Knob 3 (AMOUNT) to choose the maximum amount of modulation applied when you move your finger to the top range of the slider.
5. To route the slider to more destinations, turn Soft Knob 1 (EDIT MOD #) to find an open modulation slot and choose SLIDER.
6. Repeat steps 3-4.

Adding Aftertouch

Aftertouch is a performance feature that allows you to add modulation to a sound by applying additional pressure to a key after the key is already down. The greater the pressure applied, the more modulation is applied. The Pro 3 provides monophonic (or “channel”) aftertouch, which means that applying pressure to any key within a paraphonic chord will apply modulation to all notes currently held.

The MODULATION section lets you choose the amount of modulation applied using aftertouch and also which parameters are modulated (oscillator frequency, filter frequency, etc.). You can set either a positive or negative amount.

For example, if you select the filter cutoff as modulation destination (CUTOFF), set a positive amount of pressure, then press a key harder, the filter cutoff frequency will increase, making the filter open wider and the sound become brighter.

Conversely, if you select the filter frequency as destination, set a negative amount of pressure, then press a key harder, the filter cutoff frequency will be lowered, making the filter close more and the sound become more muted.

To choose aftertouch (pressure) as a source for modulation:

1. In the MODULATION section, press the SOURCE button. Use the Soft Knob 1 to scroll to Mod Slot 1 if it's not already displayed.
2. Use the Soft Knob 2 (SOURCE) to scroll through the various mod sources and choose PRESSURE.
3. Use the Soft Knob 4 (DESTINATION) to scroll through the various mod destinations and choose a parameter (such as CUTOFF).
4. Hold down a note on the keyboard. Then, press harder.
5. Use Soft Knob 3 (AMOUNT) to set the amount to your preference. Higher AMOUNT settings add greater modulation the harder you press a key. A negative amount setting will apply modulation in the negative direction.

The Pro 3 provides four different aftertouch/pressure response settings. The default setting provides a linear response. To choose a different response curve, use the AFTERTOUCH CURVE parameter in the GLOBAL menu.

Distortion

The Pro 3 features analog distortion which can be used to add warmth, harmonic complexity, and an aggressive edge to sounds. The character of the distortion is affected by the harmonic content of a program. Sounds with more high-end will sound different than sounds with fewer harmonics. To add distortion, use the front-panel DISTORTION knob.

DISTORTION

Distortion: 0...127—Sets the distortion amount.

Play List

The Play List enables you to organize programs into lists for quick recall. This feature is particularly useful for live performance where you may want to have specific groups of programs at your fingertips.

Here's how the Play List works:

• There are 10 sets.
  • Each set contains 4 Lists.
  • Each list contains 4 programs.

    G --> H["P6U2 P3U4 P5U1"]

The Play List Menu

To create a Play List:

1. Press the PLAY LIST button.
2. Turn Soft Knob 4 to select SET 1.
3. Turn Soft Knob 3 to select LIST 1.
4. Press Soft Button 1 to select the first position in the list.
5. Use Soft Knob 1 (PROGRAM) and Soft Knob 2 (BANK) to choose the program that you want.
6. Press Soft Button 2 to select the second position in the list.
7. Use Soft Knob 1 (PROGRAM) and Soft Knob 2 (BANK) to choose the program that you want.

8. Press Soft Button 3 to select the third position in the list.

9. Use Soft Knob 1 (PROGRAM) and Soft Knob 2 (BANK) to choose the program that you want.

10. Press Soft Button 4 to select the forth position in the list.

11. Use Soft Knob 1 (PROGRAM) and Soft Knob 2 (BANK) to choose the program that you want.

12. Now that you have set up List 1. Repeat as desired to set up List 2, List 3, and List 4, if you want.

13. The Lists that you have just created all reside in Set 1. If you want, turn Soft Knob 4 to Set 2 and repeat the entire process to create another 4 lists that will then reside in List 2. You can continue doing this for all 10 sets, if you want.

Play Lists simply point to stored Factory or User programs. Editing and saving a program changes that program in memory and, as a result, in any Play Lists in which it appears. If you need a program to behave differently in different situations, save multiple copies of the program edited and named appropriately for each situation.

To export Play Lists as MIDI SysEx data, use DUMP PLAYLISTS command in the Global menu with a computer and MIDI utility such as SysEx Librarian. All Play List data will be exported as a SysEx file.

To recall programs from a Play List:

1. Press the PLAY LIST button.

2. Turn Soft Knob 4 to select the Set you want (1-10).

3. Turn Soft Knob 3 to select the List you want (1-4).

4. Use Soft Buttons 1-4 to choose the program you want within the currently selected Set and List.

Miscellaneous Parameters

Pressing the MISC PARAMS button displays the miscellaneous parameters menu. Here you'll find settings for Key Modes, Gate Source, Alternate Tunings, Glide, and the Pitch Wheel.

To use the MISC PARAMS menu:

1. Press the MISC PARAMS button.
2. Use Soft Buttons 1-3 to select the desired menu.

Key Modes Tab

Key Mode (sometimes called note priority) determines what note has priority when more than one note is played on the keyboard or via MIDI.

• Low (note) Priority is most common in vintage synths and is often used for playing trills by holding a note and repeatedly tapping a lower note.
• Low (note) Retrigger causes the envelopes to be retriggered with each keystroke.
• High (note) and High Retrigger are similar to the low note settings, except that the highest note is given priority.
• Last (note) and Last Retrigger give priority to the last note played.

Key Mode: Low Note, High Note, Last Note—(In the KEY MODES tab) Selects the key priority when more than one key is played simultaneously. LOW NOTE, HIGH NOTE and LAST NOTE are monophonic playback modes that give priority to the lowest, highest, or last note played, as their names imply.

Retrigger: On, Off—(In the KEY MODES tab) Determines whether or not the envelopes are retriggered if a note is held while additional notes are played.

Gate Source

Gate Source determines the source that triggers the Pro 3's envelopes.

Keyboard: Selects normal envelope triggering using the Pro 3 keyboard.

ExtAudio: Selects envelope triggering using an external audio source connected to the audio in connector on the rear of the Pro 3.

Scale

By default, the Pro 3 is set to standard, chromatic western tuning. Additionally, it supports 64 additional, alternative tunings. These range from Indonesian Gamelan tunings to even more esoteric modes. To select an alternative turning, use Soft Knob 4 to scroll through the SCALE menu. For descriptions of the included tunings, see page 130.

Alternative tunings can be enabled on a per-program basis here, or globally for all programs by using the SCALE parameter in the GLOBAL menu.

Glide Tab

As explained previously, Glide causes the pitch of a note to glide up or down from the pitch of the previously played note. Glide is turned on and off using the GLIDE switch, but the RATE must also be set. If the GLIDE button is on, but RATE is set to 0, glide has no effect.

Glide can be set individually for each oscillator.

Glide Mode: FixRate, FixRate A, FixTime, FixTime A—(In the KEY MODES tab) These modes determine how GLIDE behaves:

FixRate: The time to transition between notes varies with the interval between the notes; the greater the interval, the longer the transition time. The glide rate is fixed.

FixRate A: The same as FixRate, but glide is only applied when playing legato. That is, glide only occurs when a note is held until the next note is played. This effectively allows glide to be turned on and off from the keyboard.

FixTime: Glide is set to a fixed time, regardless of the interval between notes.

FixTime A: The same as FixTime, but glide only occurs when playing legato.

Pitch Wheel Tab

You can set a range in semitones for the Pitch wheel, depending on your playing preference. The range is 12 semitones up (1 octave) and 24 semitones down (2 octaves).

Range Up: Off, 1...12 Semitones—(In the PITCH WHEEL tab) Selects the range in semitones when bending the Pitch Wheel upward. Twelve semi-tones equals 1 octave.

Range Down: Off, 1...24 Semitones—(In the PITCH WHEEL tab) Selects the range in semitones when bending the Pitch Wheel downward. Twenty-four semitones equals 2 octaves.

Global Settings

The GLOBAL menu is where you'll find settings that apply to the synthesizer as a whole — in other words, settings that apply to the overall behavior of the synth. These include such things as master tuning, keyboard velocity curves, MIDI settings, Pitch and Mod wheel calibration, and more.

You can use the GLOBAL button to set the program that appears when you power on the Pro 3. Simply use the BANK and PROGRAM knobs to find the program you want, then press the GLOBAL button twice. That program is now the default program on start up.

To use the GLOBAL menu:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to scroll through the list of parameters.
3. To set a selected parameter, turn Soft Knob 3 or press Soft Button 1, as necessary.

Here are descriptions of all of the GLOBAL menu parameters.

1. Master Coarse Tune: -12...+12—Master Transpose control; a setting of 0 is the equivalent of concert pitch. This control steps in semitones one octave up (+12) or down (-12).
2. Master Fine Tunet: -50...+50—Master Fine Tune control; 0 centered. Steps in cents as much as a quarter-tone up (+50) or down (-50).
3. MIDI Channel: All, 1...16—Selects which MIDI channel to send and receive data, 1 to 16. Choosing ALL receives on all 16 channels.
4. MIDI Clock Mode: Sets the synthesizer's ability to send and receive MIDI clock messages:

• OFF: MIDI Clock is neither sent nor received
- MASTER: MIDI Clock is sent, but not received.
- SLAVE: MIDI Clock is received, but not sent.
• SLAVE THRU: MIDI Clock is received and passed to MIDI Out
- SLAVE NO S/S (no start and stop): Receives MIDI Clock but does not respond to MIDI Start or Stop command.

In SLAVE and SLAVE THRU modes, if no MIDI clock is present at the selected input, the Arpeggiator and Sequencer will not function.

1. MIDI Clock Cable In: MIDI Port, USB—Sets the port (MIDI or USB) by which MIDI clock is received.

2. MIDI Clock Cable Out: MIDI 1, MIDI 2, USB, MIDI ALL, ALL—Sets the port by which MIDI clock is sent.

3. MIDI Param Send: Off, CC, NRPN—Changes to the values of front panel controls are transmitted via MIDI as Non-registered Parameter Number (NRPN) controllers or as Continuous Controllers (CC). Transmission of parameters can also be turned off.

NRPNs are the preferred method of parameter transmission, since they cover the complete range of all parameters, while CCs are limited to a range of 128.

1. MIDI Param Receive: Off, CC, NRPN—Sets the method by which parameter changes are received via MIDI. As with transmission, NRPNs are the preferred method.

2. MIDI Control Enable: Off, On—When On, the synth will respond to MIDI controllers, including Pitch Wheel, Mod Wheel, Pedal, Breath, Volume, and Expression.

3. MIDI Sysex Enable: On, Off—Sets whether MIDI System Exclusive data will be received or ignored.

4. MIDI Sysex Cable: None, MIDI Port, USB—Sets the port, MIDI or USB, by which System Exclusive data will be transmitted and received.

5. MIDI Out Select: Off, MIDI 1, MIDI 2, USB, MIDI All, All—Sets the port(s) by which MIDI data will be transmitted.

6. MIDI Program Send: Off, On—When On, the synth will transmit MIDI Program Change and other SysEx messages to the MIDI Out.

7. MIDI Program Receive: Off, On—When On, the synth will respond to received MIDI Program Change and other SysEx messages.

8. MIDI Arp Notes: Off, On—When On, the synth's Arpeggiator outputs MIDI note numbers. You can use this feature to drive other MIDI-equipped devices such as synthesizers and drum machines.

9. Arp Beat Sync: Off, Quantize—When set to QUANTIZE, Arpeggiator note playback occurs only on the beat, regardless of when you press a key on the keyboard.

10. Local Control: All Off, Key/Wheels Off, On—When on (the default), the keyboard and front panel controls directly affect the Pro 3. When off, the controls are transmitted via MIDI but do not directly affect the “local” synth (that is, the Pro 3). When KEY/WHEELS OFF is selected the front controls are enabled (so that you can edit them) but the keyboard and Pitch/Mod wheels are off. This is primarily useful for avoiding MIDI data loops that can occur with some external Sequencers.

11. Mono/Stereo: Stereo, Mono—The Pro 3 defaults to stereo operation. When set to Mono, this parameter defeats all pan settings and modulation, effectively making each of the outputs a mono output.

12. Pot Mode: Relative, Passthru, Jump—The rotary controls on the Pro 3's front panel are a mixture of “endless” rotary encoders and potentiometers or “pots.” The pots are identifiable by their lined knobs and limited amount of travel. There are three pot modes to determine how the synth reacts when the programmable parameters are edited. (Master volume is not programmable, so these modes don’t apply.)

When set to RELATIVE, changes are relative to the stored setting. In Relative mode, the full value range is not available until either the minimum or maximum value and the respective lower or upper limit of the pot's travel is reached.

For example, the Resonance parameter has a value range of 0 to 254. Let's say the physical position of the Resonance pot is the equivalent of a value of 200. If you switch to a program that has a stored Resonance setting of 63 and turn the pot all the way up, it will only go to 117. To get to the maximum value of 255, you first have to turn down until the value is at the other extreme and the pot is at the limit of its travel (in this case, 0 and fully counter-clockwise, respectively).

In PASSTHRU mode, turning the pot has no effect until after the edited value equals the preset value (that is, until the edited value “passes through” the stored value).

JUMP mode uses an absolute value based upon the position of the pot when edited: turn a pot and the value jumps immediately from the stored value to the edited value.

1. Footswitch Polarity: Normal, Reversed—There are two types of momentary footswitches, normally open and normally closed. Either type can be used with the Sustain switch input. This setting allows you to accommodate both models in case yours behaves in a way that is the opposite of what you expect due to its polarity. (Sustain is on until the footswitch is pressed and then it turns off, which is the opposite of the expected behavior.) Connect your pedal and choose the appropriate setting based on its behavior.

2. Footswitch Function: Sustain, Arp Hold, Arp Hold Mom—Sets the function for the Sustain pedal input the rear of the synthesizer. Selecting SUSTAIN chooses normal sustain pedal operation. Selecting ARP HOLD and pressing the sustain pedal causes the Arpeggiator to hold the current arpeggio as if you had pressed the hold button on the front panel. Selecting HOLD MOM causes the Arpeggiator to sustain (even when you release the notes on the keyboard) for as long as you hold down the pedal. Releasing the Sustain pedal stops the Arpeggiator.

3. Pedal Polarity: Normal, Reversed—There are two types of pedals, normally open and normally closed. Either type can be used with the Sustain switch input. This setting allows you to accommodate both models in case yours behaves in a way that is the opposite of what you expect due to its polarity. Connect your pedal and choose the appropriate setting based on its behavior.

4. Pedal Function: LPF Full, LPF Half—When you use an expression pedal connected to the PEDAL jack to control filter cutoff, this sets the range of modulation sent. With LPF FULL selected, an expression pedal connected to the FILTER jack will control filter cutoff frequency within its full range of 0-1019 (fully closed to fully open). With LPF HALF selected, an expression pedal connected to the FILTER jack will control filter cutoff frequency within half of its range (fully closed to half open).

5. Aftertouch Enable: On, Off—Selects whether aftertouch (key pressure) is enabled or disabled. If disabled, the Pro 3 will neither respond to nor transmit aftertouch/key pressure data.

6. Aftertouch Curve: Curve 1, Curve 2, Curve 3, Curve 4—Sets one of four pressure curves for the keyboard to adjust the aftertouch to your playing style.

7. Velocity Curve: Curve 1... Curve 8—Sets one of the eight velocity curves for the keyboard to adjust the velocity response to your playing style.

8. Scale (Alt Tuning): Equal Temperment, 1...17—Selects one of the Pro 3's built-in tunings. Set to 1. EQUAL TEMPERMENT, the tuning is standard, chromatic tuning. Choosing 2 through 65 selects an alternative, non-chromatic, non-Western scale that can be used to emulate ethnic instruments or in other creative ways. See “Appendix C: Alternative Tunings” on page 82 for a description of each tuning. Additional tunings can be imported as a SysEx message. Note that alternative tunings can be enabled globally here, or on a per-sound basis by using the SCALE parameter in the KEY MODES tab of the MISC PARAMS menu.

9. CV 1 In Offset: -127...+128—Allows adjustment of the DC offset of control voltage input 1.

The Pro 3 is flexible when it comes to Control Voltages, and it can be configured to accurately interact with virtually all Eurorack modules. The Pro 3's CV inputs and outputs have a range of 0 to 10v. Since the range is 0-10v, Middle C is sent from the CV output at 5v. This allows the CV out to track over a 10 octave range, from 0 to 10v. There is no standard input voltage range for Eurorack modules. Some modules and external synthesizers have a 10v input range, while others have a 5v input range. For example, if you want a 0-5v range, set offset to 64.

Using the CV OFFSET parameter, you can configure the Pro 3 as necessary to work correctly with your specific module. You can also assign the keyboard and Sequencer of the Pro 3 to transmit CV data at 1v/octave by assigning NOTE NUMBER to modulate CVs 1-4 OUT with an Amount of 127 in the Mod Matrix.

1. CV 2 In Offset: -127...+128—Allows adjustment of the DC offset of control voltage input 2.

2. CV 3 In Offset: -127...+128—Allows adjustment of the DC offset of control voltage input 3.

3. CV 4 In Offset: -127...+128—Allows adjustment of the DC offset of control voltage input 4.
4. CV 1 In Scale: -127...+128—Allows adjustment of the input scale of control voltage input 1.

The Pro 3's oscillators can both drive and be driven by control voltages. Because the electronics in any device are rarely perfect, CV In and Out scaling allows you to make slight adjustments so that the Pro 3 and any connected CV devices are in tune with each other.

1. CV 2 In Scale: -127...+128—Allows adjustment of the input scale of control voltage input 2.
2. CV 3 In Scale: -127...+128—Allows adjustment of the input scale of control voltage input 3.
3. CV 4 In Scale: -127...+128—Allows adjustment of the input scale of control voltage input 4.
4. CV 1 Out Offset: -127...+128—Allows adjustment of the DC offset of control voltage output 1.
5. CV 2 Out Offset: -127...+128—Allows adjustment of the DC offset of control voltage output 2.
6. CV 3 Out Offset: -127...+128—Allows adjustment of the DC offset of control voltage output 3.
7. CV 4 Out Offset: -127...+128—Allows adjustment of the DC offset of control voltage output 4.

Chapter 3: Programming the Pro 3

The Pro 3 can produce a vast spectrum of sounds. While the factory programs give you some idea of its scope, if you only make use of its presets, you're not really using the Pro 3 to its full potential. The real excitement is in creating sounds that are uniquely your own.

This chapter provides some brief tutorials. While there isn't enough space here to cover how to use every Pro 3 function, the examples will help you get familiar with some basic concepts. Making sounds you've never heard before can be very rewarding.

Synthesis 101: Synth Bass

Some of the best synth bass sounds consist of a single oscillator, a bit of filter resonance, the right envelope, and not much else. So start with the Basic Program and go from there.

Short Version

To create a classic synth bass:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to navigate to BASIC PROGRAM and press Soft Button 1 (WRITE NOW).
3. Set filter CUTOFF to 40 (refer to the main display).
4. Set filter RESONANCE to 100.
5. In the ENVELOPES section, set the Filter Envelope's ENV AMOUNT to 50.
6. Play a low note on the keyboard. Instant synth bass!
7. Experiment with the Filter Envelope's ENV AMOUNT and DECAY settings.

Long Version with Explanations

Here's a more detailed version that provides insight into the process. You'll start with the Basic Program, then learn how to choose an appropriate oscillator waveshape, how to use the filter, how to use the envelopes, and how to use Unison to fatten things up.

In the Basic Program, only Oscillator 1 is audible. Its waveshape is set to sawtooth and its level is 127 in the MIXER. (Oscillator 2 and Oscillator 3 levels are set to zero.)

To start with the Basic Program:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to navigate to the BASIC PROGRAM command, then press Soft Button 1 (WRITE NOW).

Each of the waveforms have their own unique sound:

• The sawtooth waveform is a good starting point for sounds because it has plenty of harmonics. This gives you a lot to work with in terms of a raw sound that you can filter and modulate.
• The pulse (square) wave is a good starting point, too, but sounds different than the sawtooth, because of its different harmonic content. The sawtooth has even-numbered harmonics and the square wave has odd-numbered harmonics. (Google this if you want to learn more.)
• The sine wave has no harmonics. It's useful used alone for its pure tone, or in combination with another oscillator or sample(s) to reinforce the fundamental pitch of a sound and add weight.
• On Oscillator 3, the super sawtooth is a stacked version of the sawtooth and sounds very thick when you use the SHAPE MOD knob to detune it. It's great for brass, strings, and classic dance music sounds.

To listen to the various oscillator waveshapes:

1. In the OSCILLATORS section, the Sawtooth waveform is selected by default. Play and hold a note, then turn the SHAPE knob to step through the various waveshapes.

2. Select the sawtooth waveshape.

Next, you'll use the filter to shape the raw sound of the sawtooth wave.

To adjust the filter:

1. Press and hold down a key and turn the filter's CUTOFF knob. Notice how it cuts the high frequencies as you rotate counter-clockwise, making the sound of the oscillator less bright. If you turn the CUTOFF knob fully counterclockwise you'll filter out all frequencies and hear nothing.

2. Return the CUTOFF knob to its halfway position, play and hold a note again then turn the RESONANCE knob about halfway up. Notice how the sound changes as a band of frequencies near the cutoff is amplified.

3. Rotate the filter's CUTOFF knob again and you'll hear a classic resonant filter sweep. You're going to use this to create your synth bass.

4. Set the filter CUTOFF to a value of 40 (refer to the main display to see its numeric value).

5. Set the filter RESONANCE to a value of 100. This is going to give the synth bass its funky “zap.”

6. Play a note and listen to the sound. At this point you won't hear anything because you've mostly closed the filter. You'll need to open the filter using the filter envelope (so you don't have to turn the CUTOFF knob by hand).

Now, you'll use the filter envelope to control the filter sweep.

To adjust the filter envelope:

1. In the Envelopes section, turn the Filter Envelope's AMOUNT knob to a value of 50 (refer to the main display to see its numeric value).

2. Play a low note on the keyboard. Instant synth bass!

Notice how the sound has changed. The Filter Envelope is controlling filter cutoff by the amount you set with the AMOUNT knob.

1. Continue experimenting with the Filter Envelope's AMOUNT knob. Notice how greater AMOUNT settings amplify the effect of the envelope on the filter.

2. Repeatedly strike a note on the keyboard as you turn the Filter Envelope's DECAY knob clockwise and counterclockwise. Notice how it changes the sound as the note decays faster or slower.

Be aware that the Filter Envelope and Amplifier Envelope work in conjunction, with the Filter Envelope controlling how the filter opens and closes and the Amplifier Envelope controlling the overall volume shape. To learn more about the Amplifier Envelope, see page 35

1. The Filter Envelope's RELEASE parameter acts in conjunction with the Amplifier Envelope. In other words, you can't hear a long release on the filter envelope if the amplifier envelope is short! So to hear the filter envelope's RELEASE parameter in action, first set the Amp Envelope's RELEASE value to 75.
2. Now repeatedly strike a note on the keyboard as you turn the Filter Envelope's RELEASE knob clockwise and counterclockwise. Notice how the note fades out faster or slower as you change the RELEASE value.

Now you know how to create a simple synth bass program using the most essential synthesizer components of the Pro 3: the oscillators, the filters, and the envelopes. Using just these three things you can create an enormous variety of sounds. Keep experimenting with them and if you like what you’ve created, save the programs in one of the user banks. (See “Saving a Program” on page 10.)

Creating Synth Brass

Here's another easy-to-construct sound: synth brass, with a classic “pitch blip” effect on the attack. In this example you’ll learn how to detune the super saw wave, and how to use an auxiliary envelope to modulate the pitch of oscillator 2 to simulate an aggressively blown horn effect.

To create synth brass:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to navigate to BASIC PROGRAM and press Soft Button 1 (WRITE NOW). As a shortcut, hold down the front-panel TRANSPOSE DOWN button and press the HOLD button.
3. In the mixer, turn up Oscillator 2 to 127. (Osc 1 is already at 127.)
4. In the OSCILLATORS section, set both oscillators to the sawtooth wave and osc 2 PITCH to -5 to detune and thicken them.

5. In the display press Soft Button 2 to select the oscillator SHAPE menu then use Soft Knob 4 to set OSC SLOP to 10 to add extra oscillator drift.

6. In the FILTER section, set CUTOFF to 26, RESONANCE to 15, and DRIVE to 100.

7. In the FILTER ENVELOPE section, set the AMOUNT to 105, the ATTACK to 17, DECAY to 64, SUSTAIN to 50, and RELEASE to 90.

8. Enable touch sensitivity by pressing and enabling the VELOCITY button.

9. In the AUXILIARY ENVELOPE section, select ENVELOPE 1 and set its destination to osc 2 COARSE FREQ. This routes envelope 1 to modify Osc 2 pitch according to its ADSR (attack, decay, sustain, release) settings. This will create the slight pitch variation at the beginning of the sound (the "pitch blip").

You can quickly assign the mod destination for Envelope 1 by holding down the envelope's selector button and turning the Oscillator 2 frequency knob. This will auto-assign the modulation destination to the envelope.

1. Set the auxiliary AMOUNT to 35 and DECAY to 20.

2. Play some notes in the upper range of the keyboard. Classic synth brass!

3. Experiment with different auxiliary envelope AMOUNT and DECAY settings to fine tune the “pitch blip” effect.

Turning Synth Brass into a Paraphonic String Pad

It's a simple matter to turn the previous synth brass sound into a string pad by simply adjusting its envelope and filter settings.

To turn the synth brass into a string pad:

1. Enable Paraphonic mode by pressing the paraphonic button on the front panel.

2. Turn up the level of Oscillators 1, 2, and 3 to 127.

3. Set all three oscillators to a sawtooth wave. And set their OCTAVE to 2.

4. In the FILTER section, set the CUTOFF to 800 and RESONANCE to 122.

5. In the FILTER ENVELOPE section, set the ENV AMOUNT to 12.

6. Set filter envelope ATTACK to 59, DECAY to 75, SUSTAIN to 67, and RELEASE to 71.

7. Set amplifier envelope ATTACK to 66, DECAY to 62, SUSTAIN to 124, and RELEASE to 80.

8. Play some chords. You've now got a good basic string pad.

Adding Effects to the String Pad

You can enhance the string pad adding an effect such as chorus and phas-ing for a retro feel.

To add effects to the string pad:

1. In the EFFECTS section, press the EFFECT 1 button.
2. Turn the EFFECT TYPE knob and choose CHORUS.
3. Set MIX to 62, then set parameter 1 (DEPTH) to 131, parameter 2 (RATE) to 40, and parameter 3 (LPF CUTOFF) to 127.
4. Play some chords. Classic string machine! For a retro 70's era string synth, let's add the phaser.
5. Press press the EFFECT 2 button.
6. Turn the EFFECT TYPE knob and choose PHASER.
7. Set MIX to 64, then set parameter 1 (DEPTH) to 179, parameter 2 (RATE) to 15, and parameter 3 (FEEDBACK) to 255.
8. Play some chords. Retro string machine! For even more dramatic phasing, set MIX to 127.

Creating a Hard-Sync Lead

Here's another classic sound: a hard-sync lead. A famous example of this is “Let’s Go” by the Cars (performed on a Prophet-5). In this example you’ll learn how to hard-sync the oscillators, pitch-modulate one of them with an auxiliary envelope, then add effects.

To create a hard-sync lead:

1. Press the GLOBAL button.
2. Use Soft Knob 1 to navigate to BASIC PROGRAM and press Soft Button 1 (WRITE NOW). As a shortcut, hold down the front-panel TRANSPOSE DOWN button and press the LATCH button.
3. In the mixer, turn up Oscillator 2 to 127. (Osc 1 is already at 127.)
4. In the OSCILLATORS section, set both oscillators to sawtooth.
5. On Oscillator 1, enable the SYNC 1 button. (See page 19 for an explanation of hard sync.)
6. Set Oscillator 1's OCTAVE to 1. This will allow for a wide range of pitch modulation in step 9.
7. In the AUX ENVELOPE section, select ENVELOPE 1.
8. In the display, press Soft Button 1 (AUX 1 DEST) and use Soft Knob 1 to choose osc 1 COARSE FREQ as the destination. This routes envelope 1 to modulate Oscillator 1 pitch according to its ADSR (attack, decay, sustain, release) settings.
9. Set the auxiliary ENV AMOUNT to 127 and ATTACK to 23, DECAY to 60, SUSTAIN to 100, and RELEASE to 65. This will set the amount and “shape” of the modulation.
10. Play some notes. Classic hard-sync lead!
11. Experiment with Aux Envelope 1's Attack, Decay, Sustain, and Release settings to better understand how these affect the shape of pitch modulation routed to Oscillator 1.

Adding Effects to the Lead

You can enhance the sync lead by adding some delay and reverb.

To add effects:

1. In the EFFECTS section, press the EFFECT 1 button.
2. Turn the EFFECT TYPE knob and select DELAY STEREO.
3. Set MIX to 30, then set parameter 1 (TIME) to 135, parameter 2 (FEEDBACK) to 20, and parameter 3 (LPF) to 100.
4. In the EFFECTS section, press the EFFECT 2 button.
5. Turn the EFFECT TYPE knob and select SUPER PLATE.
6. Set MIX to 30, then set parameter 1 (TIME) to 100, parameter 2 (TONE) to 138, and parameter 3 (PREDELAY) to 12.
7. Play some notes. Perfect hard-sync lead!

A Final Word

The examples given in this chapter are fairly basic, but they give you some idea of the power of synthesis. Imagine what you can create by using these as starting points, then modulating the filters, oscillators, and even effects with LFOs, Auxiliary Envelopes, the Sequencer, and other modulation sources.

It's often useful to start with a simple sound and make it progressively more complex, saving edited versions as you go so that you can retrace your steps and branch off at different points in the sound design process if you want.

We wish you many enjoyable hours of experimentation!

Chapter 4: Using the Pro 3 with External Devices

This chapter explains how to use the Pro 3 to process external audio, how to synchronize the Pro 3's Sequencer to an external MIDI device, and how to use the Pro 3 with a modular synthesizer.

Processing External Audio

The Pro 3 makes a great effects processor. The example below shows you how connect external audio to the Pro 3 and process it in real time by tweaking knobs and controls.

To hear an external audio signal, you need to gate the amplifier and filter open.

When you do this, you will also hear the Pro 3's oscillators droning since they're continuously producing sound. To avoid continuous oscillator drone, set the LEVEL of all oscillators to zero in the Mixer.

To process external audio:

1. Connect an instrument or audio signal to the AUDIO IN jack on the rear of the Pro 3 and turn up the instrument to a suitable level.
2. Press the HOLD button then play a key on the keyboard. This holds the VCA open.
3. To avoid continuous oscillator drone, set the LEVEL of all oscillators to zero in the Mixer.
4. Turn up the EXT AUDIO knob in the Mixer section of the Pro 3. (If you need to further boost the signal, adjust INPUT LEVEL and INPUT GAIN. When you adjust the EXT AUDIO knob in the mixer, these controls appear in the display.
5. Turn the SUSTAIN knob on the amplifier envelope to 127.
6. Turn the SUSTAIN knob on the filter envelope to 127.
7. Play the external audio source.
8. Tweak parameters such as filter cutoff, distortion, drive, tuned feedback, effects, and so on to process the sound.

Filtering External Audio Using the Envelope Follower

The Pro 3's envelope follower makes it easy to process external audio with an “auto-wah” type effect. Add a little distortion and delay and this is a very expressive effect.

The Envelope Follower has controls for ATTACK and RELEASE in the EXT IN ENV tab. Display these parameters by turning the EXT AUDIO knob in the Mixer.

Input Attack Input Release
80 INPUT ATTACK 99 INPUT RELEASE
Mixer Ext In

To avoid continuous oscillator drone, set the OUTPUT LEVEL of all Pro 3 oscillators.

To filter external audio with the envelope follower:

1. Connect an instrument or audio signal to the AUDIO IN jack on the rear of the Pro 3 and turn up the instrument to a suitable level.
2. Press the HOLD button then play a key on the keyboard. This holds the VCA open.

3. To avoid continuous oscillator drone, set the LEVEL of all oscillators to zero in the Mixer.

4. Turn the SUSTAIN knob on the amplifier envelope to 127.

5. Turn the SUSTAIN knob on the filter envelope to 127.

6. Press the SOURCE button in the Modulation section.

7. With Soft Knob 2 (SOURCE) choose ENV FOLLOW as the source.

8. With Soft Knob 4 (DESTINATION) choose ENV VCA AMT as the destination.

9. With Soft Knob 1 (EDIT MOD) choose a second available mod slot.

10. With Soft Knob 2 (SOURCE) choose ENV FOLLOW as the source.

11. With Soft Knob 4 (DESTINATION) choose CUTOFF as the destination.

12. Use Soft Knob 3 to adjust the modulation AMOUNT for both modulation routings. Try a setting of +120 for the ENV VCA AMOUNT parameter and a setting of +90 for the CUTOFF parameter.

13. Play the external audio source.

14. Turn up the EXT AUDIO knob in the Mixer section of the Pro 3. (If you need to further boost the signal, adjust INPUT LEVEL and INPUT GAIN. When you adjust the EXT AUDIO knob in the mixer, these controls appear in the display.

15. Set the IN GATE THRESH to 100. You can adjust this later if necessary.

16. As the external audio source continues to play, show the Envelope Follower's ATTACK and RELEASE parameters in the display by turning the EXT AUDIO knob in the mixer. Try an ATTACK setting of 5 and RELEASE setting of 38.

17. Adjust the front panel filter CUTOFF and RESONANCE parameters. Try a CUTOFF setting of 0 and RESONANCE setting of 160.

18. Adjust any other parameters such as distortion and delay to tailor the sound.

Connect an expression pedal to the Pro 3 and route it to filter cutoff in the mod matrix for more real-time control over the wah effect.

Syncing the Sequencer with an External MIDI Device

It's possible to sync the Pro 3's Sequencer to an external MIDI device such as a Tempest drum machine or digital audio workstation using MIDI clock.

To sync a sequence to an external MIDI clock:

1. Connect the external MIDI device's MIDI Out to the MIDI In of the Pro 3.
2. Set the external MIDI device to MIDI Clock Master.
3. On the Pro 3, press the GLOBAL button and select MIDI CLOCK MODE (menu item 4). Then set MIDI CLOCK MODE to SLAVE.
4. Also in the GLOBAL menu, set MIDI CLOCK CABLE IN to either MIDI or USB depending on your setup.
5. Press the ARPEGGIATOR button twice to display the Sequencer parameters in the display (the second button press turns off the Arpeggiator).
6. Press Soft Button 2 to select the SEQ PARAMS menu.
7. Press the PLAY button on the Sequencer.
8. Start MIDI playback on the external device. The Pro 3 Sequencer will start and stop playback in response to MIDI Start/Stop/Continue messages.

If you have a Sequencer track assigned to a MIDI channel output and it is only sending MIDI note-off messages, check the value of the Velocity parameter for each step. A velocity greater than zero must be set for a MIDI note-on message to be sent. If the velocity for a given step is set to zero, only a MIDI note-off message will be sent for that step.

Using Pro 3's CV Outs to Control a Modular Synth

The Pro 3 can interface with modular synthesizers through its four control voltage inputs and outputs. This makes it possible to use the Pro 3 as the central hub of a modular system.

For example, you could play the modular synth's oscillators from the Pro 3 keyboard. You could also use the Pro 3's Sequencer to modulate the external modular synth's filters. You could even use the Pro 3's Touch slider and Mod Wheel to perform real-time modulation of the modular synth. The possibilities are extensive.

In the example below, the Pro 3 keyboard is used to play the oscillator of a modular synth.

To use the Pro 3's CV Outs to control the oscillator of a modular synth:

1. Using a 3.5 mm patch cable, connect the Pro 3's CV Out 1 to the appropriate CV In on the modular synth's oscillator module. (The modular synth's input should support a 1-volt-per-octave signal.)

2. On the Pro 3, press the SOURCE button in the MODULATION section.

3. Using Soft Knob 1, choose an available mod slot.

4. Using Soft Knob 2, select NOTE NUMBER number as the mod source.

5. Using Soft Knob 4, select cv 1 out as the mod destination.

6. Using Soft Knob 3, set the mod AMOUNT to 127. (Anything less than this will affect pitch scaling.)

7. Play the Pro 3 keyboard. The modular synth's oscillator should respond to the notes. (You may need to tune the modular synth's oscillators to match the Pro 3's oscillators.)

Use the same basic procedure to route modulation sources such as

Sequencer tracks, the touch slider, the mod wheel, and so on, to the modular synth. In this way you can use the Pro 3 as the central controller for a larger modular system.

If pitch tracking between the Pro 3's keyboard and the external oscillator module isn't perfect, you may need to scale the Pro 3's CV output.

To scale the Pro 3's CV Out:

1. Play the note A = 440 on the Pro 3 keyboard.
2. Tune the external modular oscillator to the same pitch.
3. Play different octaves to check for pitch consistency across the key range.
4. If the pitch scaling isn't perfect, press the GLOBAL button and in the display, select CV OUT SCALE for the CV output that you're using (in the previous example, CV 1 OUT).
5. Use Soft Knob 3 to tweak the scaling while you play different octaves across the keyboard. Keep adjusting until scaling across the entire key range is correct.

More About Pro 3's CV Outputs

The Pro 3 is flexible when it comes to Control Voltages, and it can be configured to accurately interact with virtually all Eurorack modules. The Pro 3's CV outputs have a range of 0 to 10v. Since the range is 0-10v, Middle C is sent from the CV output at 5v. This allows the CV out to track over a 10 octave range, from 0 to 10v.

There is no standard input voltage range for Eurorack modules. Some modules and external synthesizers have a 10v input range, while others have a 5v input range. Using the CV OFFSET parameter in the GLOBAL menu, you can configure the Pro 3 as necessary to work correctly with your specific module.

You can also assign the keyboard and Sequencer of the Pro 3 to transmit CV data at 1v/octave by assigning NOTE NUMBER to modulate CV OUT (1-4) with an AMOUNT of 127 in the Mod Matrix.

For example, if the Pro 3 sends CV at 1v/octave to an oscillator that has a maximum input range of 5v, sending Middle C from the Pro 3 will result in the oscillator playing at its highest frequency.

There are a couple ways to correct for this offset:

• Use an external attenuator.
• Alternatively, apply a negative offset to the desired CV output using the CV OUT OFFSET parameter in the GLOBAL menu. This will allow the Pro 3 to compensate for the voltage difference internally.

To configure the Pro 3 to control an external oscillator that has a 5v input range:

1. In Mod Slot 1, choose NOTE NUMBER as the source and choose CV 1 OUT as the destination. Then set the modulation AMOUNT to 127. This will set the CV 1 output to scale at 1v/octave when a note is played.
2. Press the GLOBAL button and set CV 1 OUT OFFSET to -64. The offset of -64 will apply a -5v offset to the CV.
3. An external oscillator with a 5v range will now track at the same octave as the Pro 3's internal oscillators.

General guidelines:

• a CV OUT OFFSET value of -16 equals a -1.25v offset to the CV output.
• a CV OUT OFFSET value of -32 equals a -2.5v offset to the CV output.
• a CV OUT OFFSET value of -48 equals a -3.75v offset to the CV output.

And so on.

You can also make incremental adjustments to the CV OUT OFFSET to fit your specific application.

Appendix C: Troubleshooting and Support

Troubleshooting

If you're experiencing problems or unexpected behavior from your Pro 3, here are a few typical scenarios and their solutions:

If the Pro 3 isn't producing sound:.

1. Recall the Basic Program by holding the Transpose DOWN button and pressing the LATCH button.
2. If the problem is still there, check the following:

• Volume - make sure it is set to an appropriate value
- Rear-panel output jacks - make your audio cables are connected to LEFT/RIGHT OUTPUT.
• In the GLOBAL menu, make sure that LOCAL CONTROL is set to ON.

If the sequencer or arpeggiator has stopped running:

- Check the MIDI CLOCK MODE setting in GLOBAL to ensure the Pro 3 is set to MASTER or OFF. Or if set to SLAVE or SLAVE THRU or SLAVE NO S/S, make sure the Pro 3 is receiving MIDI clock.

If some of the programs sound different than usual:

- In the Global menu, check SCALE/ALT TUNING and make sure it's set to EQUAL TEMPERAMENT. Also, check the Mod wheel position. The Mod wheel can do more than just add vibrato. Also, check the MIDI CLOCK MODE setting in the GLOBAL menu to ensure the Pro 3 is set to MASTER or OFF. Or if set to SLAVE or SLAVE THRU or SLAVE NO S/S, make sure the Pro 3 is receiving MIDI clock.

If there is a ground hum in the audio output:

- USB can cause ground loops, so try to resolve any grounding issues between the computer (if connected) and the Pro 3. Or use MIDI, which is opto-isolated.

If the Pro 3 is behaving erratically:

- This is almost always caused by a MIDI feedback loop. Make sure that any MIDI Thru functionality is turned off on the MIDI interface/hardware or in the MIDI software application. Disconnect all Pro 3 MIDI connections (MIDI and USB cables) and see if the problem persists. You can also monitor the MIDI traffic with MIDI Monitor (Mac OS) or MIDI-OX (Windows) to see if the Pro 3 is being overrun with duplicate messages.

If the Pro 3 doesn't seem to respond to its controls:

• Make sure LOCAL CONTROL is ON in the GLOBAL menu.

If MIDI System Exclusive data is not transmitted/received:

- Make sure that the MIDI SYSEX CABLE setting in the GLOBAL menu is set to USB or MIDI depending on which you are using to transmit or receive MIDI messages.

If the Pro 3 plays out of tune:

- Check the MASTER COARSE and MASTER FINE parameter in the GLOBAL menu to make sure they are both set to 0.

- You may need to recalibrate the oscillators. See “Calibrating the VCOs and Filters” on page 126.

If the pitch or Mod wheel doesn't go to full range:

- Recalibrate the Pitch and Mod wheels. See “Calibrating the Pitch and Mod Wheels” on page 126.

If the touch slider doesn't go to full range:

- Recalibrate the touch sliders. See “Calibrating the Pitch and Mod Wheels” on page 126.

If the filter sounds strange or out of tune:

- You may need to recalibrate the filters. See “Calibrating the VCOs and Filters” on page 126.

Resetting the Global Parameters

If you're trying to track down a problem, it's sometimes a good idea to reset the Global parameters to their defaults. This is a quick way to make sure that the Pro 3 returns to its factory settings.

To reset all Global parameters to their default settings:

1. Press the GLOBAL button.

2. Use the SOFT KNOB 1 to select RESET GLOBALS, then press Soft Button 1 (RESET NOW). Globals are reset. You can now can play the Pro 3 again.

Contacting Technical Support

If you are still having a problem with the Pro 3, contact Technical Support at [e-mail]. Please include the purchase date of your Pro 3, its serial number, and the operating system version. Press the GLOBAL button to see this at the bottom of the main display.

If you haven't already reset the Global parameters and run the calibration routines (see Troubleshooting), you should do it before contacting Technical Support. This is probably the first thing you will be asked to do.

Warranty Repair

Sequential warrants that the Pro 3 will be free from defects in materials and/or workmanship for 1 year from the date of purchase. Please register your product online at wwwApply.com to establish the date of purchase. (This is not a requirement for warranty service, but it will help expedite the process.)

Appendix D: Calibrating the Pro 3

Because the Pro 3 is calibrated at the factory, controls such as the Pitch and Mod wheels, Touch Slider, and analog filters shouldn't require re-calibration. But if you experience unexpected behavior with these controls, you can use the calibration function to tune them occasionally.

Calibrating the VCOs and Filters

To calibrate the VCOs and filters:

1. Press the GLOBAL button.
2. Use the Soft Knob 1 to select CALIBRATE VCOS & FILTERS, then press Soft Button 1 (START TUNING).
3. The synthesizer performs its auto-calibration procedure. Don't turn off the power while it's doing this.
4. When finished, the front panel controls will return to normal and you can play the Pro 3 again.

Calibrating the Pitch and Mod Wheels

To calibrate the Pitch and Mod wheels:

1. Press the GLOBAL button.
2. Use the SOFT KNOB 1 to select CALIBRATE WHEELS, then follow the instructions in the display.
3. When finished, press the GLOBAL button again to exit the GLOBAL menu. You can now can play the Pro 3 again.

Resetting the Global Parameters

If you're trying to track down a problem, it's sometimes a good idea to reset the Global parameters to their defaults. This is a quick way to make sure that the Pro 3 returns to its factory settings.

To reset all Global parameters to their default settings:

1. Press the GLOBAL button.
2. Use the Soft KNOB 1 to select RESET GLOBALS, then press Soft Button 1 (RESET NOW). Globals are reset. You can now can play the Pro 3 again.

Appendix E: Exporting and Importing Programs and Banks

You can use the DUMP CURRENT PROGRAM, DUMP CURRENT BANK, and DUMP ALL USER BANKS commands in the GLOBAL menu to transmit the current program, bank, or all banks in SysEx format via the selected MIDI port. This allows you to save your programs so that you can share or archive them. You will need a computer and software application such as SysEx Librarian for Macintosh, or MIDIOX for Windows.

To export a program or bank as a SysEx file over USB:

1. Connect your synthesizer to a computer using a USB cable.
2. Open your MIDI librarian software (SysEx Librarian, etc.) and configure it to receive SysEx messages.
3. Press the GLOBAL button on the Pro 3.
4. Use the SOFT KNOB 1 to select MIDI SYSEX CABLE, then use the Soft Knob 3 knob to choose USB.
5. Use the SOFT KNOB 1 to select DUMP CURRENT PROGRAM, DUMP CURRENT BANK, or DUMP ALL USER BANKS, depending on which of these you would like to do.
6. Press Soft Button 1 (DUMP NOW). The program or bank is exported

Dumped programs will load back into the same bank and program location in memory when received by the Pro 3 via MIDI.

Programs can also be dumped directly from one Pro 3 to another using the MIDI DIN jack, if the MIDI SYSEX CABLE parameter is set to MIDI in the GLOBAL menu.

To send a program or bank to another Pro 3 as a SysEx file over MIDI:

1. Connect two Pro 3 synthesizers together using MIDI cables and the MIDI IN AND MIDI OUT jacks on their rear panels.
2. On both synthesizers, press the GLOBAL button and use SOFT KNOB 1 to select MIDI SYSEX CABLE, then use Soft Knob 3 to choose MIDI.
3. On the Pro 3 that you want to send the programs to, press the GLOBAL button again to disable it.
4. On the Pro 3 that you want to send the programs from, in the GLOBAL menu use SOFT KNOB 1 to select DUMP PROG, DUMP BANK, or DUMP ALL BANKS, depending on which of these you would like to do.
5. Press Soft Button 1 (DUMP NOW). The program or bank is exported to the other Pro 3.

Dumped programs will load back into the same bank and program location in memory when received by the Pro 3 via MIDI.

Importing Programs and Banks

You can use a MIDI librarian application such as such as SysEx Librarian for Macintosh, or MIDI-OX for Windows to transmit exported program or banks back into your Pro 3. You will need a computer and an appropriate software application.

To import a program or bank as a SysEx file over MIDI:

1. Connect your synthesizer to a computer using a USB cable (or MIDI cable, if you are using a dedicated MIDI interface).
2. Press the GLOBAL button on your Pro 3.

3. Use the Soft Knob 1 to select MIDI SYSEX CABLE, then use Soft Knob 3 to choose either USB or MIDI, depending on which port you are using to connect to your computer.

4. Open your MIDI librarian software and configure it to send SysEx messages to your Pro 3.

5. In the MIDI librarian, open the programs and/or banks you want to send.

6. Transmit the programs. The Pro 3 should load them. They will replace any existing programs in those same memory locations on the synth.

Programs will load back into the same bank and program locations from which they were originally exported.

Appendix E: Alternative Tunings

By default, the Pro 3 is set to standard, chromatic western tuning.

Additionally, it supports up to 64 additional alternative tunings, which you can access using the SCALE parameter in the GLOBAL menu (to apply a tuning globally) and also the MISC PARAMS menu (to apply a tuning to a specific program).

These 64 alternative tunings range from Equal temperament to Indonesian Gamelan tunings. If you want, you can replace these with other tunings that you can find on the Internet. These must be in SysEx format. You can download them into the Pro 3 using SysEx Librarian for Mac or MIDI-OX for Windows.

Here are descriptions of the first 17 default Pro 3 alternative tunings. Descriptions for tunings 18-64 can be found on the Pro 3 Support page of Sequential's website.

1. 12-Tone Equal Temperament (non-erasable)

The default Western tuning, based on the twelfth root of two.

2. Harmonic Series

MIDI notes 36-95 reflect harmonics 2 through 60 based on the fundamental of A = 27.5 Hz. The low C on a standard 5 octave keyboard acts as the root note (55Hz), and the harmonics play upwards from there. The remaining keys above and below the 5 octave range are filled with the same intervals as Carlos' Harmonic 12 Tone that follows.

3. Carlos Harmonic Twelve Tone

Wendy Carlos' twelve note scale based on octave-repeating harmonics. A = 1/1 (440 Hz). 1/1 17/16 9/8 19/16 5/4 21/16 11/8 3/2 13/8 27/16 7/4 15/8

4. Meantone Temperament

An early tempered tuning, with better thirds than 12ET. Sounds best in the key of C. Use this to add an authentic touch to performances of early Baroque music. C=1/1 (260 Hz)

5. 1/4 Tone Equal Temperament

24 notes per octave, equally spaced 24root2 intervals. Mexican composer Julian Carillo used this for custom-built pianos in the early 20th century.

6. 19 Tone Equal Temperament

19 notes per octave (19root2) offering better thirds than 12 ET, a better overall compromise if you can figure out the keyboard patterns.

7. 31 Tone Equal Temperament

Many people consider 31root2 to offer the best compromise towards just intonation in an equal temperament, but it can get very tricky to keep track of the intervals.

8. Pythagorean C

One of the earliest tuning systems known from history, the Pythagorean scale is constructed from an upward series of pure fifths (3/2) transposed down into a single octave. The tuning works well for monophonic melodies against fifth drones, but has a very narrow palate of good chords to choose from. C=1/1 (261.625 Hz) 1/1 256/243 9/8 32/27 81/64 4/3 729/512 3/2 128/81 27/16 16/9 243/128

9. Just Intonation in A with 7-Limit Tritone at D#

A rather vanilla 5-limit small interval JI, except for a single 7/5 tritone at D#, which offers some nice possibilities for rotating around bluesy sevenths. A=1/1 (440 Hz) 1/1 16/15 9/8 6/5 5/4 7/5 3/2 8/5 5/3 9/5 15/8

10. 3-5 Lattice in A

A pure 3 and 5-limit tuning which resolves to very symmetrical derived relationships between notes. A=1/1 (440 Hz) 1/1 16/15 10/9 6/5 5/4 4/3 64/45 3/2 8/5 5/3 16/9 15/8

11. 3-7 Lattice in A

A pure 3 and 7-limit tuning which resolves to very symmetrical derived relationships between notes. Some of the intervals are very close together, offering several choices for the same nominal chords. A=1/1 (440 Hz) 1/1 9/8 8/7 7/6 9/7 21/16 4/3 3/2 32/21 12/7 7/4 63/32

12. Other Music 7-Limit Black Keys in C

Created by the group Other Music for their homemade gamelan, this offers a wide range of interesting chords and modes. C=1/1 (261.625 Hz) 1/1 15/14 9/8 7/6 5/4 4/3 7/5 3/2 14/9 5/3 7/4 15/8

13. Dan Schmidt Pelog/Slendro

Created for the Berkeley Gamelan group, this tuning fits an Indonesian-style heptatonic Pelog on the white keys and pentatonic Slendro on the black keys, with B and Bb acting as 1/1 for their respective modes. Note that some of the notes will have the same frequency. By tuning the 1/1 to 60 Hz, Dan found a creative way to incorporate the inevitable line hum into his scale. Bb, B = 1/1 (60 Hz) 1/1 1/1 9/8 7/6 5/4 4/3 11/8 3/2 3/2 7/4 7/4 15/8

14. Yamaha Just Major C

When Yamaha decided to put preset microtunings into their FM synth product line, they selected this and the following tuning as representative just intonations. As such, they became the de-facto introduction to JI for many people. Just Major gives preferential treatment to major thirds on the sharps, and a good fourth relative to the second. C= 1/1 (261.625) 1/1 16/15 9/8 6/5 5/4 4/3 45/32 3/2 8/5 5/3 16/9 15/8

15. Yamaha Just Minor C

Similar to Yamaha's preset Just Major, the Just Minor gives preferential treatment to minor thirds on the sharps, and has a good fifth relative to the second. C= 1/1 (261.625) 1/1 25/24 10/9 6/5 5/4 4/3 45/32 3/2 8/5 5/3 16/9 15/8

16. Harry Partch 11-Limit 43 Note Just Intonation

One of the pioneers of modern microtonal composition, Partch built a unique orchestra with this tuning during the first half of the 20th century, to perform his own compositions. The large number of intervals in this very dense scale offers a full vocabulary of expressive chords and complex key changes. The narrow spacing also allows fixed-pitched instruments like marimbas and organs to perform glissando-like passages. G = 1/1 (392 Hz, MIDI note 67)

1/1 81/80 33/32 21/20 16/15 12/11 11/10 10/9 9/8 8/7 7/6 32/27 6/5 11/9 5/4 14/11 9/7 21/16 4/3 27/20 11/8 7/5 10/7 16/11 40/27 3/2 32/21 14/9 11/7 8/5 18/11 5/3 27/16 12/7 7/4 16/9 9/5 20/11 11/6 15/8 40/21 64/33 160/81

17. Arabic 12-Tone

A 12-tone approximation of an Arabic scale, which appears in some electronic keyboards designed for use with Arabic music. Not a JI scale, nor equal tempered. These are the intervals in Cents relative to C:

$$ 6 0 = \text { Cents } 0 $$

$$ 6 1 = \text { Cents } + 1 5 1 $$

$$ 6 2 = \text { C e n t s } + 2 0 4 $$

$$ 6 3 = \text { C e n t s } + 2 9 4 $$

$$ 6 4 = \text { C e n t s } + 3 5 5 $$

$$ 6 5 = \text { C e n t s } + 4 9 8 $$

$$ 6 6 = \text { C e n t s } + 6 4 9 $$

$$ 6 7 = \text { Cents } + 7 0 2 $$

$$ 6 8 = \text { C e n t s } + 8 5 3 $$

$$ 6 9 = \text { C e n t s } + 9 0 6 $$

$$ 7 0 = \text { C e n t s } + 9 9 6 $$

$$ 7 1 = \text { C e n t s } + 1 0 5 7 $$

$$ 7 2 = \text { C e n t s } + 1 2 0 0 $$

Appendix F: MIDI Implementation

The Pro 3 receives MIDI data according to the settings you have chosen in GLOBALS. In addition, there is interaction between some of the program parameters that determine the overall response of Pro 3 to MIDI data. These are the GLOBALS parameters that affect response to MIDI:

MIDI Channel: All, 1...16—Selects which MIDI channel to send and receive data, 1 to 16. All receives on all 16 channels.

MIDI Clock Mode: Sets the Pro 3's ability to send and receive MIDI clock messages:

• Off: MIDI Clock is neither sent nor received
  • Master: MIDI Clock is sent, but not received
• Slave: MIDI Clock is received, but not sent
• Slave Thru: MIDI Clock is received and passed to MIDI Out
• Slave No S/S (no start and stop): Receives MIDI Clock but does not respond to MIDI Start or Stop command.

When set to SLAVE or SLAVE THRU, if no MIDI clock is present at the selected input, the arpeggiator and sequencer will not function.

MIDI Clock Cable In: MIDI, USB—Sets the port, MIDI or USB, by which MIDI clock signals are received.

MIDI Clock Cable Out: MIDI 1, MIDI 2, USB, MIDI All, ALL—Sets the port, MIDI or USB, by which MIDI clock signals are sent.

MIDI Param Send: Off, CC, NRPN—Changes to the values of front panel controls are transmitted via MIDI as Continuous Controllers (CC) or Non-Registered Parameter Number (NRPN). Transmission of parameters can also be turned off.

NRPNs are the preferred method of parameter transmission, since they cover the complete range of all parameters, while CCs are limited to a range of 128.

MIDI Param Receive: Off, CC, NRPN—Sets the method by which parameter changes are received via MIDI. As with transmission, NRPNs are the preferred method.

MIDI Control Enable: Off, On—When set to On, the synth will respond to MIDI controllers, including pitch wheel, mod wheel, pedal, and volume.

MIDI Prog Send: Off, On—When set to On, the synth will send MIDI Program Change messages.

MIDI Prog Receive: Off, On—When set to On, the synth will respond to MIDI Program Change messages.

MIDI SysEx Cable: MIDI, USB—When set to MIDI it will receive and transmit MIDI SysEx messages using the MIDI ports/cables When set to USB it will receive and transmit MIDI SysEx messages using the USB port/cable. MIDI SysEx messages are used when sending and receiving a variety of data including, programs, alternative tunings, system updates, and more.

MIDI Out Select: Off, MIDI 1, MIDI 2, USB, MIDI ALL, All—Sets the port by which MIDI data will be transmitted.

The Non-Registered Parameter Number (NRPN) MIDI messages are used to transmit and receive both global and program parameters. They are transmitted when MIDI Parameter Send is set to NRPN in GLOBALS, and received when MIDI Parameter Receive is set to NRPN in GLOBALS.

The messages are handled in standard MIDI format using the NRPN CC commands in running status byte format. Below is the format used for transmitting a NRPN parameter.

Transmitted NRPN Messages

Status Description
1011 nnnn	Control Change
0110 0011	NRPN parameter number MSB CC
0vvv vvvv	Parameter Number MSB
0110 0010	NRPN parameter number LSB CC
0vvv vvvv	Parameter Number LSB
0000 0110	NRPN parameter value MSB CC
0vvv vvvv	Parameter value MSB
0010 0110	NRPN parameter value LSB CC
0vvv vvvv	Parameter value LSB

The parameter number can be found in the two tables below, one for global parameters, and the other for program parameters. The parameter numbers and the parameter values are broken into two 7-bit bytes for MIDI transmission; the LSB has the seven least-significant bits, and the MSB has the seven most-significant bits, though in most cases the MSB will be zero or one, and never more than two.

When receiving an NRPN, all messages do not necessarily need to be transmitted, since the synth will track the most recent NRPN number, though it is usually good practice to send the entire message above.

Once an NRPN is selected, the synth will also respond to NRPN Data Increment and Decrement commands, which some controllers utilize. Finally, it responds to one RPN (Registered Parameter Number) command, the RPN/NRPN Reset command, which can be handy for resetting the currently selected parameter to a known state.
