Main features

Analog synthesis

The VCO, VCF, and VCA are constructed of analog circuitry. With intuitively simple operation and the sound-creating process that's distinctive of analog synthesizers, the monotribe gives you a flexible and highly improvisatory synthesis experience. The VCF features the filter circuit of the classic Korg MS-20.

Self-tuning function

When not producing sound, the monotribe tunes itself internally to correct any pitch drift that may occur due to temperature changes or aging. Despite the analog VCO, the monotribe does not require regular servicing to stay in tune over time; the monotribe can deliver reliable performance as soon as the power is turned on.

Ribbon keyboard

You can switch the pitch range of the ribbon keyboard (WIDE/NARROW). Since it can also be played chromatically like a conventional keyboard, you'll be able to play melodies with accurate pitches.

Analog drum sound generator

A crisp-sounding three-part drum sound generator using discrete analog circuitry is built-in.

Eight-step sequencer

You can control the sequence in realtime to create loops using the drum sounds and the synth part.

FLUX mode

This allows the sequence of the synth part to be recorded and played back without being restricted by the steps. It's a great way to create tricky rhythms and sequence patterns with unique grooves.

Multi-function LFO

A broad range of RATE and INTENSITY settings cover everything from subtle change to drastic modulation. In addition to convention-

al LFO functionality, there's a 1SHOT mode that makes the LFO behave like an envelope genelator (EG).

External input jack

This lets you modify the sound of the synth part by mixing an external audio source with the VCO. It also lets you use the monotribe as an effect processor for an external audio source.

Internal speaker

The monotribe has a built-in speaker, so you can play it anywhere.

AC adapter or battery power

You can use batteries when you're on the go, or the AC adapter (sold separately) for extended periods of use.

How the sound generator is structured

As shown in the block diagram (p.6), the synthesizer sound generator consists of an oscillator (VCO), filter (VCF), and amp (VCA). The synthesizer will produce sound when you touch the ribbon keyboard or play back sequence data. The drum sound generator provides three parts—bass drum (BD), snare (SN), and hi-hat (HH)—and is played back by sequence data.

The three elements of sound (pitch, timbre, and volume)

Sound has three basic elements: pitch, timbre (tonal character), and volume. Just like classic analog synthesizers of the past, the monotribe provides VCO, VCF, and VCA sections that let you control these elements. Edit the VCO to modify the pitch, the VCF to modify the timbre, and the VCA to modify the volume.

In addition, you can use the envelope generator (EG) and low frequency oscillator (LFO) to dynamically control parameters.

Getting started

Installing batteries

Turn off the power before replacing the batteries.
Depleted batteries should be immediately removed from the monotribe. Leaving depletedbatteries in the battery compartment may cause malfunctions (the batteries may leak). You should also remove the batteries if you don't expect to use the monotribe for an extended period of time.
Don't mix partially-used batteries with new batteries, and don't mix batteries of differing types.
1. Detach the battery cover from the rear panel.

1. Insert six AA batteries, taking care to observe the correct polarity (+/- orientation). Use alkaline or nickel-metal hydride batteries.
2. Reattach the battery cover.
   The included battery is provided so that you can verify that the unit is operating correctly; its lifespan may be shorter than normal.

Using an AC adapter

Connect the optional AC adapter to the DC9V jack.

You must turn off the power before connecting the AC adapter.
You must only use the specified AC adapter. Using any AC adapter other than the specified model will cause malfunctions.

Battery level indication

At start-up

The step LEDs (p.15) indicate the remaining amount of battery power. If all LEDs are lit-up, the batteries are completely full. Fewer lit LEDs mean that the battery level is correspondingly lower.

If an AC adapter is connected, the remaining battery amount will not be shown correctly.
Both alkaline and nickel-metal hydride batteries are supported. In order for the remaining battery amount to be detected and shown correctly, you must use the Global menu (p.16) to specify the type of batteries that you're using.

During operation

If the batteries are running low, the monotribe will warn you by blinking the four part LEDs (p.14) simultaneously.

If the batteries run down completely, the step 1 LED will blink, and then the power will turn off automatically.

Note It's not possible to stop the low battery warning; however, you will be able to continue using the monotribe until the batteries have run down completely.
Unsaved data will be lost, so save your data (p.16) if necessary.

Connections

The following illustration shows an example of typical connections. Connect your equipment as appropriate for your needs.

You must turn off the power before connecting anything. Careless usage may damage your speaker system or cause other malfunctions.

1. Power switch

This turns the power on/off. To turn the power off, press and hold the switch.

2. DC 9V jack

Connect the optional AC adapter here.

3.AUDIO IN jack

An external audio source connected to the AUDIO IN jack will be mixed with the VCO (p.11) and sent through the VCF (p.11) and VCA (p.11). You can use this to expand the monotribe's sonic possibilities, or use it as an effect processor for a separate audio source.

A signal input in stereo will be mixed to mono.

4. OUTPUT jack

Connect the monotribe's OUTPUT jack to the INPUT jack of your mixer or powered monitor speakers. The output signal is monaural, but the jack will accept either monaural phone plugs or stereo phone plugs (unbalanced).

5. HEADPHONES jack

Connect your headphones (stereo mini-plug) here.

6. SYNC OUT jack

This jack outputs a 5V pulse of 15ms at the beginning of each step. You can use this to synchronize another monotribe or other compatible equipment such as an analog sequencer to this monotribe unit. A Global menu setting (p.16) lets you specify the polarity of the pulse.

7.SYNC IN jack

If the SYNC IN jack is connected, the internal step clock will be ignored, and the sequencer will proceed through its steps according to the pulses that are input to this jack. You can use this jack to synchronize the monotribe's steps with pulses that are output from another monotribe unit, your analog sequencer or the audio output of a DAW. A Global menu setting (p.16) lets you specify the polarity of the pulses that are detected.

8. Grounding Screw

Use this screw to ground the unit. To do so, loosen the screw and attach a grounding wire.

Do not use the unit if the screw is removed.

Depending on how the unit is connected to other devices, you may feel a slight electrical stimulation if a soft part of your skin touches a connected microphone or the metal part of the unit.

This is caused by a very weak current that is harmless to humans. If this bothers you, use this grounding screw to ground the unit externally.

Turning the power on

Before you turn on the monotribe, you must turn off the power of your powered monitors or any other external output system.

1. Turn the monotribe's LEVEL knob (p.11) and RHYTHM knob (p.15) all the way to the left.

1. Press the monotribe's power switch (p.8) to turn the power on. The step LEDs (p.15) will indicate the remaining amount of battery power.

2. Lower the volume controls of your powered monitors or external output system, and then turn their power on.

3. Turn the monotribe's LEVEL knob and RHYTHM knob clockwise to an appropriate level.
4. Adjust the volume of your external output system.

Turning the power off

1. Lower the volume of your powered monitors or external output system, and turn their power off.

2. Turn the monotribe's LEVEL knob (p.11) and RHYTHM knob (p.15) all the way to the left, and hold down the power switch until any lit LEDs have gone dark.

Never turn off the monotribe while global data (p.16) is being written. Doing so may damage the internal data.

Auto power-off

The monotribe has an auto power-off function. This function automatically turns the power off after approximately four hours have passed since the monotribe last produced sound.

Disabling the auto power-off function

If desired, you can disable the auto power-off function.

For details on this procedure, refer to the Global menu (p.16).

Panel description and functions

Synthesizer section

VCO (Voltage Controlled Oscillator)

The oscillator generates the waveform that's the basis of the sound: a sawtooth wave, triangle wave, or square wave. The noise generator produces white noise. If an external audio source is connected to the AUDIO IN jack, it will be mixed with the VCO's output. The VCO generates a waveform at a pitch that's determined by the position being touched on the ribbon keyboard or by performance data that you've recorded as a sequence. In addition, the LFO can also apply time-varying changes to the pitch.

1. OCTAVE selector

This specifies the VCO pitch in steps of an octave. With the "64" setting, the pitch range of the ribbon keyboard will be A0-D2.

2.WAVE select switch

This selects the VCO waveform: sawtooth, triangle, or square.

3.NOISE knob

This knob adjusts the level of white noise that's mixed with the VCO output.

4. RANGE select switch

This specifies the ribbon keyboard's playing mode.

WIDE	The pitch range will be extended to approximately six times that of the NARROW setting; pitch change will be continuous. The OCTAVE selector will be ignored.
NARROW	The pitch will change continuously according to the printed ribbon keyboard.
KEY	The pitch will change in chromatic steps according to the printed ribbon keyboard.

VCF (Voltage Controlled Filter)

The filter modifies the timbre (tonal character) by boosting or cutting specific frequency regions of the sound produced by the oscillator. The monotribe uses the traditional 12 dB/oct low-pass filter (LPF) that was also used on the Korg MS-20. The character of the sound will change significantly depending on the settings of this filter. In addition, you can use the LFO to modulate the filter's cutoff frequency over time.

5.CUTOFF knob

This adjusts the cutoff frequency of the VCF, affecting the brightness of the sound.

Turning the knob toward the left will darken the sound, and turning the knob toward the right will brighten the sound.

6. PEAK knob

This adjusts the resonance of the VCF, adding emphasis to the cutoff frequency.

VCA (Voltage Controlled Amplifier)

The amp varies the volume of the sound. You can use the EG to make the volume change over time.

7. LEVEL knob

This adjusts the volume.

8. EG select switch

This lets you choose one of three modulation waveforms for the EG that's applied to the VCA.

N (DECAY) The volume will start at maximum the instant the note is sounded, and will then decay.
The volume will remain at maximum while the note is played.
(ATTACK) The volume will begin increasing the instant the note is sounded, and will remain at maximum while the note is played.

LFO (Low Frequency Oscillator)

The LFO applies cyclical changes to the parameters that determine the sound. You have three choices to specify which parameters will be modulated. Since the modulation rate can be adjusted over a broad range, you can use this to create everything from vibrato to sound effects. You can also use 1SHOT mode to make the LFO behave like an EG.

9.RATE knob

This adjusts the speed of modulation. Turning the knob toward the right produces faster modulation.

10.INT.knob

This adjusts the intensity (depth) of modulation. If you turn the knob all the way to the left, no modulation will be applied.

11. TARGET select switch

This specifies what will be affected by LFO modulation.

VCO The VCO pitch will change.

VCO+VCF The VCO pitch and the VCF cutoff frequency will change.

VCF The VCF cutoff frequency will change.

12.MODE select switch

This switches the range of the modulation rate, or changes how modulation is applied.

FAST The modulation rate will have a range of approximately 1Hz to 5kHz .

SLOW The modulation rate will have a range of approximately 0.05Hz to 18Hz .

1SHOT When the note begins, the first half-cycle of modulation will be applied, and then the LFO will stop.

NOTE KEY SYNC is applied if you select FAST or 1SHOT.

A note played with 1SHOT

About KEY SYNC

Key Sync is a function that resets the phase of the LFO waveform when a note is played.

13.WAVE select switch

This selects the modulation waveform: sawtooth wave, triangle wave, or square wave. (p.11)
