1 MIC GUITAR 2 3

1. Plug in your dynamic or condenser mic here.

Use the MIC digital rotary encoder on the top panel (4) to engage the -20 dB pad (push) and/or 48V phantom power (push and hold) for a condenser mic, if necessary.

Make sure 48V power is turned OFF BEFORE plugging anything in to the mic input. Only engage 48V power when a device that requires it is plugged in.

1. Plug in your guitar here using a standard quarter-inch guitar cable. This input is designed with the high-impedance characteristics necessary to properly handle both passive and active guitar pickups. To make your guitar sound and "feel" even more like it is plugged directly into a actual guitar amplifier, consider using MOTU's ZBox guitar impedance adapter (sold separately), which simply goes between your guitar cable and this input (no extra cable needed).

2. This is a standard quarter-inch headphone jack. To control volume, push the VOL rotary encoder (5) repeatedly until the phones LED is lit. You can control phone volume independently or together with main out volume.

To obtain your product serial number, see "Obtaining your MicroBook serial number" on page 14.

1. Connect to a host computer with a standard USB cable (Type A to Type B). When connected to laptop or desktop computer, the MicroBook IIc is powered by this USB 2.0 connection.
2. This USB 2.0 Micro-B jack is for power only. DO NOT use this port to connect to a host computer. Use it for power when connecting the MicroBook IIc to an iPad. For details, see "Connecting to an iOS device" on page 18.
3. This stereo, 24-bit S/PDIF digital output mirrors the Main Out.
4. This eighth-inch "stereo mini" jack serves as an alternative input for Line Inputs 3-4. For example, you

can plug in an iPod or CD player here, instead of using the quarter-inch jacks to the right. DO NOT plug a cable into this mini jack at the same time as the quarter-inch jacks. To avoid ground loop noise, don't connect a device with another power source (such as an iPod connected to a computer).

1. These two analog inputs are balanced TRS (tip/ring/sleeve) quarter-inch connectors that can also accept an unbalanced plug. These inputs (3-4) do not have mic pre-amps, so they are best used for synthesizers, drum machines, effects processors, and other devices with line level signals (either -10 or +4). The CueMix FX software lets you adjust the input

level for recording. If you use these quarter inch jacks, DO NOT plug a cable in to the stereo mini jack.

1. This eighth-inch "stereo mini" jack serves as a stereo line level analog output that is completely independent from the Main Out (to the right).
2. These two balanced, quarter-inch jacks serve as the MicroBook's main outputs. You can connect them to a set of powered studio monitors. To control volume, push the VOL knob on the top repeatedly until the speaker LED is lit. You can hear the output of your audio software on these Main Outs, and also use CueMix FX to monitor live MicroBook inputs.

To minimize noise that may be produced by connected devices:

• Use balanced TRS quarter-inch cables whenever possible.
• Use the MicroBook's balanced quarter-inch connectors instead of the eighth-inch stereo "mini" connectors whenever possible.
• Don't make unbalanced audio connections between the MicroBook and a FireWire or USB device while the other device is connected to any computer.

Quick Reference: MicroBook Top Panel

1. The MIC digital rotary encoder controls the trim for the mic input. The preamp provides 53 dB of gain. Push to toggle the -20 dB pad; push and hold to toggle the 48V phantom power.

Make sure 48V power

is turned OFF BEFORE plugging anything in to the mic input. Only engage 48V power when a device that requires it is plugged in.

1. Three-LED metering for the LINE IN jacks.

2. Stereo three-LED metering for the MAIN OUTs.

3. Four-LED metering for the MIC input and GUITAR input. In "Guitar Trim Mode" (see below), these meters indicate the input level setting (not signal activity).

4. Three-LED metering for the LINE OUTs.

5. The VOL digital rotary encoder controls the volume of the main outs and phones. Push it repeatedly to cycle among three states:

a) Main outs (speaker icon)

b) Phones (headphone icon)

c) Both

Push and hold the VOL encoder to enable Guitar Trim Mode. In this mode, you can use the VOL knob to adjust the guitar input level; the MIC knob continues to adjust the mic input level, as usual. The MIC and GTR signal activity meters (4) become level indicators. If the level is turned all the way down, the the bottom LED flashes.

With a variety of I/O formats, dedicated mic and guitar inputs, and no-latency mixing and processing of live input, the MicroBook is a complete, portable “studio in a box” when used with a Mac, PC or iOS device.

Precision Digital Trim™

The MicroBook's mic and guitar inputs are equipped with digitally controlled analog trims with up to 51 dB and 32 dB of boost, respectively, using the included CueMix FX software for Mac OS X and Windows. This allows you to fine-tune trim settings for optimum levels.

Different trim configurations can then be saved as files on disk for instant recall.

16-bit and 24-bit recording

The MicroBook system handles all data with a 24-bit signal path, regardless of the I/O format. You can record and play back 16-bit or 24-bit audio files at any supported sample rate via any of the MicroBook's inputs and outputs.

CueMix FX mixing and effects

All MicroBook inputs and outputs can be routed to the on-board CueMix FX 8-bus (four stereo) digital mixer driven by hardware-based DSP. The mixer allows you to apply no-latency EQ and dynamics processing to inputs, outputs or busses directly in the MicroBook hardware, independent of the computer. Input signals to the computer can be recorded wet, dry, or dry with a wet monitor mix (for musicians during recording, for example).

Effects include parametric EQ and compression/limiting. Standard compression provides conventional threshold, ratio, attack, release, trim, and knee controls. The 7-band parametric EQ is modeled after British analog console EQs, featuring four filter styles (gain/Q profiles) to effectively cover a wide range of audio material. Low-pass and high-pass filters are also supplied with slopes that range from 6 to 36 dB.

The MicroBook's flexible effects architecture allows you to apply EQ and compression on every input and output.

CHAPTER 3 Installing the MicroBook Software

NO SOFTWARE INSTALLATION FOR iOS DEVICES

The MicroBook IIc is a USB audio class compliant device, so it can be used as a simple 4-input, 6-output audio interface (with no mixing or processing features) for iPad and other iOS devices. No software installation is required. Just connect the MicroBook to your iOS device as explained in “Connecting to an iOS device” on page 18, and access it in your iOS audio software as instructed for your audio software.

MAC SOFTWARE INSTALLATION

To install the MicroBook software:

1 Insert the MOTU Universal Installer disc or download the installer from motu.com/download.
2 Launch the installer.
3 Follow the directions that the installer gives you.

What does the installer do?

The installer checks the computer to make sure it satisfies the minimum system requirements for your MOTU interface. If so, the installer proceeds with the Mac OS X installation. Drivers are installed, along with the CueMix FX application.

Class compliant operation under OS X

The MicroBook IIc is a USB audio class compliant device, so OS X will recognize it as a simple 4-input, 6-output audio interface, even without the MicroBook drivers installed. When operating in this mode, the MicroBook can be used as a simple audio interface (with no mixing or processing) with any Mac audio software. However, it is still recommended that you run the software installer, so that you can take full advantage of all the professional features offered by the MicroBook.

WINDOWS SOFTWARE INSTALLATION

Before you connect the MicroBook audio interface to your PC and turn it on, it is best to install the software drivers first. This ensures that all the MicroBook components are properly installed in your system.

PC installation goes more smoothly if you install the software before connecting the MicroBook hardware.

To install the MicroBook software on your PC:

1 Insert the MOTU Universal Installer disc or download the installer from motu.com/download.
2 Launch the installer.
3 Follow the directions that the installer gives you.

If Windows asks you to locate the drivers

If you've already connected the MicroBook to your computer, Windows probably issued an alert notifying you that the MicroBook requires drivers, followed by another window asking you to locate the drivers on disk. If this happens:

1 Cancel the driver search.
2 Disconnect the MicroBook.
3 Run the MicroBook Software Installer as instructed in the previous section.

CUEMIX FX

The CueMix FX application (for Mac and Windows) is installed on your hard drive during software installation. It provides a mixing console that gives you control over the MicroBook's on-board mixing, EQ and dynamics processing. It also provides access to all MicroBook settings. For details, see chapter 7, "CueMix FX" (page 37).

- CueMix FX is not required for iOS operation, as the MicroBook IIc operates as a simple 4-input, 6-output audio interface for iOS, with no mixing or processing features.

AUDIODESK WORKSTATION SOFTWARE (MAC AND WINDOWS)

AudioDesk is an advanced digital audio workstation software package for the MicroBook that lets you record, edit, mix, process, bounce and master multi-track audio projects.

WINDOWS USERS: INSTALL THE SOFTWARE FIRST

PC installation goes more smoothly if you install the MicroBook software (previous chapter) before you connect the MicroBook hardware (this chapter).

ABOUT USB CABLES

The MicroBook IIc includes two USB cables: one for connecting to a host computer, and another for connecting to a power outlet (for iOS device operation).

Host computer USB 2.0 cable

The standard host computer USB cable (included) has Type A and Type B connectors.

Type A Type B

Figure 4-1: Use this standard Type A to Type B cable for connection to a host computer.

Micro-B USB 2.0 cable for power

The Micro-B USB cable (included) is a standard USB 2.0 cable with Type A and Micro-B connectors. You can use any similar standard USB cable.

Micro-B Type A

Figure 4-6: Powering the MicroBook from a power outlet when connected to an iPad or other iOS device.

CONNECT INPUTS AND OUTPUTS

Here are a few things to keep in mind as you connect other devices.

Mic input with preamp

Connect a dynamic or condenser microphone to the mic input (Figure 4-7) with a standard mic cable.

Do not connect a +4 (line level) input to the mic input (because it will overdrive the preamp).

Phantom power

If you are connecting a condenser microphone or other device that requires 48V phantom power, you can enable phantom power for the mic input using the MIC knob on the top panel: push and hold the knob to toggle 48V, as indicated by the 48V LED. See “Quick Reference: MicroBook Top Panel” on page 6.

Alternately, you can use the MicroBook's CueMix FX software. See "Input settings" on page 21.

Make sure 48V power is turned OFF before plugging anything in to the mic input.

Only engage 48V power when a device that requires it is plugged in.

20 dB pad

If the input signal is still too hot with the trim turned all the way down, engage the -20dB pad by pushing the MIC knob or by enabling it in the CueMix FX Channel tab (Figure 4-9). See “Input settings” on page 21.

Guitar input

Plug in your guitar to the guitar input (Figure 4-7). You can trim the level using the CueMix FX software. See “Input settings” on page 21.

For ultra-realistic sound and feel when producing guitar tones with processing software (amp modeling, cabinet modeling, virtual effects pedals, etc.), consider using MOTU's ZBox guitar impedance adapter (sold separately), which adds proper impedance characteristics that cannot be modeled in software. Visit motu.com for details.

Line level inputs

The quarter-inch analog line level inputs 3-4 (Figure 4-8) are balanced (TRS) connectors that can also accept an unbalanced plug. Alternately, you can use the eighth-inch stereo mini plug for line level input (from an iPod or other source).

Figure 4-7: MicroBook llc front panel

MIC GUITAR 1 2

Do not use the stereo mini input and quarter-inch inputs at the same time. If you are using the mini jack, unplug the quarter-inch jacks. If you are using the quarter-inch jacks, unplug the mini jack.

Further settings for the line inputs, such as stereo pairing and pan settings for mid/side micing are available in the CueMix FX software. See “Input settings” on page 21.

Trim

The mic and guitar inputs are equipped with 51 dB and 32 dB (respectively) of digitally controlled analog trim (boost). The line inputs can also be trimmed. Adjust the trim level for the mic input using the MIC knob. Other inputs can be trimmed using the MicroBook's CueMix FX software. See “Input settings” on page 21.

Main outs

In a standard studio configuration, the main outs (Figure 4-8) are intended for a pair of studio monitors, but they can also be used as outputs for any purpose. The quarter-inch main outs are calibrated to produce a +4 dBu line level output signal.

Line out

Use the eighth-inch stereo mini line out jack for output to desktop speakers or any other line level destination.

Digital out

The S/PDIF RCA “digital out” connector provides stereo digital audio output to another device: the S/PDIF output always mirrors the Main Outs.

Tips for connecting other devices

Follow these simple guidelines to minimize noise that may be produced by other devices connected to the MicroBook:

■ Use balanced TRS quarter-inch cables whenever possible. Balanced connections greatly reduce noise resulting from electrical interference.

■ Use the MicroBook's balanced quarter-inch connectors instead of the eighth-inch stereo “mini” connectors whenever possible.

- Don’t make unbalanced audio connections between the MicroBook and a FireWire or USB device while the other device is connected to any computer, as this could significantly reduce the audio quality performance of the MicroBook.

INPUT SETTINGS

To access input channel settings such as 48V phantom power, pad and trim, launch the MicroBook's CueMix FX software and follow this procedure:

1 Click the Inputs tab (Figure 4-9).
2 Adjust the settings for each input channel as desired. The Focus button exposes further settings for the input in the Channel tab (4).
3 Each input can be trimmed.
4 Click the Channel tab (4) to access the channel's input settings.

Input metering while adjusting trim Use the long-throw, horizontal input level meter (5) at the top of the channel settings section (Figure 4-9) to calibrate the level.

BUS POWER

Bus power requirements

When connected to a computer, the MicroBook draws all the power it needs from the USB HOST connection to the computer. However, the USB connection to the computer must meet all of the requirements discussed below.

USB adapter products must be powered. If you are using a USB adapter or hub (a third-party product that supplies one or more USB ports to your computer), it must have direct access to a power supply:

■ PCI USB cards — If you plan to connect the MicroBook to a PCI card and run the MicroBook under bus power, the PCI card must have a direct connection to the power supply harness inside your computer. This is the same power supply harness to which you connect internal hard drives, CD/DVD drives, etc.

■ PCMCIA, Cardbus or ExpressCard slot adapters — If you plan to connect the MicroBook to a PC card, Cardbus or ExpressCard USB adapter (inserted in the card slot in your laptop), it must provide a powered connection and it must also have its own power supply. Most commonly, these types of products have a DC power adapter that plugs into an AC wall outlet. As you can see, however, this situation does not allow for remote battery operation, as the card adapter requires AC.

Examples of bus-powered operation

Bus power from a desktop computer Your desktop computer is running off of its usual AC power connection, and the MicroBook draws power from the USB cable connected to the computer. There are no limits to running time.

Bus power from an AC-powered laptop This scenario is identical to the desktop situation described above: the laptop is powered by AC, the MicroBook is powered via the USB bus and there are no limits to running time.

Bus power from a battery-powered laptop

The laptop is being powered by its own battery, and the MicroBook is being powered by its USB connection to the computer, so the laptop battery is supplying power to both the laptop and the MicroBook. This is the most compact and portable operating scenario. Running time is determined by the capacity of the laptop battery. Alternately, you can power the MicroBook through its Micro-B USB power port (see below).

AC POWER

As shown in Figure 4-6 on page 18, the MicroBook IIc can be powered from a wall outlet or other AC power source using the supplied power adapter and a Micro-B USB cable. This connection is required when using the MicroBook with iOS devices. This connection can be used optionally to power the MicroBook when it is connected to a battery-powered laptop.

A TYPICAL MICROBOOK SETUP

Here is a typical MicroBook studio setup. When using it with a computer, all mixing and processing can be done either in the MicroBook, in the computer with audio software, or both. During recording, you can use the MicroBook's

CueMix™ FX mixer to apply EQ and compression to what you are recording and monitor it via the main outs, headphone outs, or any other output pair. You can control everything from the included CueMix FX software.

CHOOSING THE MICROBOOK DRIVER

Once you've made the preparations described so far in this chapter, you're ready to run your audio software and enable the MOTU MicroBook Core Audio driver. Check the audio system or audio hardware configuration window in your software. There will be a menu there that lets you choose among various drivers that may be in your system. Choose the MOTU MicroBook from this menu, as discussed in the following sections.

Digital Performer and AudioDesk

Choose the MicroBook as your audio input output device by choosing Configure Audio System>Configure Hardware Driver from the Setup menu. This window shows MicroBook settings such as sample rate and clock source.

Pro Tools

In Avid Pro Tools, go to the Setup menu and choose Playback Engine. Choose the MicroBook from the Current Engine menu. For information about the H/W Buffer Size setting, see “Adjusting the audio I/O buffer” on page 29.

Pro Tools 9 or later is required.

Logic Pro

In Logic Pro, go to the Preferences window, click the Audio tab, click the Drivers tab and click the Core Audio tab. Choose the MOTU MicroBook from the Output and Input device menus. For info about the I/O Buffer Size setting, see “Adjusting the audio I/O buffer” on page 29.

Garage Band

In Garage Band, go to the Audio/MIDI preferences and choose MOTU MicroBook from the Audio Output and Audio Input menus. For information about the Optimize for setting, see “Adjusting the audio I/O buffer” on page 29.

Cubase and Nuendo

Go to the Device Setup window. Click the VST Audio System item in the Devices list and choose MOTU MicroBook from the ASIO Driver menu. For information about the Audio Buffer Size setting, see “Adjusting the audio I/O buffer” on page 29.

Live

In Ableton Live, access the preferences window and click the Audio tab. Choose CoreAudio from the Driver Type menu. Choose the MOTU MicroBook from the Input Audio Device and Output Audio Device menus. For information about the Buffer Size setting, see “Adjusting the audio I/O buffer” on page 29.

Reason and Record

In Propellerhead Reason and Record, go to the Preferences window, choose Audio preferences from the menu and choose MOTU MicroBook from the Audio Output menu. For information about the Buffer Size setting, see “Adjusting the audio I/O buffer” on page 29.

Reaper

In Cockos Reaper, access the Preferences and click Devices under the Audio preferences. Choose MOTU MicroBook from the Audio Device menu.

Other audio software

For other audio applications, the procedure is similar to that shown above. Consult your owner's manual for further information.

SAMPLE RATE

Choose the desired overall sample rate for the MicroBook system in your host software. Newly recorded audio will have this sample rate.

CLOCK SOURCE

Some host software may have a “clock source” setting. For the MicroBook, there is only one choice for clock source: Internal.

BUFFER SIZE

Most host applications provide a Buffer setting, which can be adjusted to reduce the delay — or monitoring latency — that you hear when live audio is patched through your host software. For example, you might have a mic, guitar, and MIDI synth connected to the analog inputs of the MicroBook. If so, you will often be mixing their live input with audio material recorded in your host software. See “Monitoring live input” below.

INPUTS AND OUTPUTS

Once you've enabled the MicroBook's Core Audio driver, MicroBook audio inputs and outputs will appear in your host software wherever audio inputs and outputs are listed.

PROCESSING LIVE INPUTS WITH HOST-BASED EFFECTS PLUG-INS

If you patch a live input (such as a microphone or guitar) through a plug-in effect in your host software, you might hear a slight delay. There are several ways to reduce this delay. For details, see “Monitoring live input” on page 28.

WORKING WITH CUEMIX FX MIXING AND EFFECTS

The MicroBook provides powerful external mixing, EQ and compression, which you can operate hand-in-hand with your host's mixing environment. For example, the MicroBook can serve as a monitor mixer routing channels to musicians, or it can serve as an integrated extension of your host's mixing environment. If you program a MicroBook mixing and processing configuration that goes hand in hand with your host project, be sure to use the configuration export features in CueMix FX to save the MicroBook settings as a file in your host project folder for instant recall of all settings. See chapter 7, "CueMix FX" (page 37) for complete details.

24-BIT OPERATION

Your MicroBook hardware fully supports 24-bit recording with host software that also supports 24-bit operation. Consult the documentation for your host software for further information about enabling 24-bit operation.

MONITORING LIVE INPUT

There are two ways to monitor live audio input with a MicroBook:

1 Through the computer

2 Via the MicroBook CueMix FX hardware mixer

Figure 5-2 below shows method #1, which allows you to apply host-based effects processing via plug-ins in your audio software. See the next section,

“Adjusting the audio I/O buffer” for details about how to reduce or eliminate the audible monitoring delay that the computer introduces.

Figure 5-3 on page 29 shows method #2. CueMix FX hardware-based monitoring lets you hear what you are recording with no monitoring delay and no computer-based effects processing. Rather, input is routed directly to an output, either with or without MicroBook-based effects processing (EQ or compression). See

graph TD
    A["1. Live input (from mic, guitar, etc.) enters the MicroBook."] --> B["2. Mic signal goes immediately to the computer."]
    B --> C["3. Mic signal is 'patched thru' back to the audio interface with host-based plug-in effects, if any."]
    C --> D["4. Mic signal (with plug-in processing, if any) is routed to the main outs (or other outputs that you've specified in the software)."]

Figure 5-2: There are two ways to monitor live audio inputs with a MicroBook: 1) through the computer or 2) via CueMix FX hardware monitoring. This diagram shows method 1 (through the computer). When using this method, use your host software's buffer setting to reduce the slight delay you hear when monitoring the live input, but don't lower it too much, or your computer might get sluggish.

"CueMix FX hardware monitoring" later in this chapter for details on how to use CueMix FX with your audio software, or with CueMix FX.

If the material you are recording is suitable, there is a third way to monitor live input: use both methods (Figure 5-2 and Figure 5-3) at the same time. For example, you could route guitar to both the computer (for an amp model effect) and mix that processed signal on the main outs with dry guitar from CueMix FX.

ADJUSTING THE AUDIO I/O BUFFER

A buffer is a small amount of computer memory used to hold data. For audio interfaces like the MicroBook, buffers are used for the process of transferring audio data in and out of the computer. The size of the buffers determines how much delay you hear when monitoring live inputs through your audio software: larger buffers produce more delay; smaller buffers produce less.

1. CueMix FX immediately patches the live mic signal directly to the main outs (or other output), completely bypassing the computer. This signal could be dry, or with MicroBook effects processing, such as EQ or compression.

Figure 5-3: This diagram shows the signal flow when using CueMix FX no-latency monitoring. Notice that this method does not process the live input with plug-ins in your audio software. Instead, you can apply MicroBook effects, such as the EQ and/or compression.

Under OS X, audio I/O buffer size is handled by the host audio application (not the MicroBook Core Audio driver). Most audio software applications provide an adjustable audio buffer setting that lets you control the amount of delay you'll hear when monitoring live inputs or processing them with software plug-ins. Below are a few examples. For more examples, see chapter 5, "Mac OS X Audio Software" (page 25).

Lower latency versus higher CPU overhead

The buffer setting has a large impact on the following things:

■ Patch thru latency
■ The load on your computer's CPU
■ Possible distortion at the smallest settings
■ How responsive the transport controls are in your host audio software

The buffer setting presents you with a trade-off between the processing power of your computer and the delay of live audio as it is being patched through your software. If you reduce the size, you reduce patch thru latency, but may significantly increase the overall processing load on your computer, leaving less CPU bandwidth for things like real-time effects processing. On the other hand, if you increase the buffer size, you reduce the load on your computer, freeing up bandwidth for effects, mixing and other real-time operations.

Audio Performance Audio Performance Processing Playback

Figure 5-7: When adjusting the buffer size to reduce monitoring latency, watch the 'Processing' meter in Digital Performer or AudioDesk's Performance Monitor. If you hear distortion, or if the Performance meter is peaking, try raising the buffer size.

If you are at a point in your recording project where you are not currently working with live, patched-thru material (e.g. you're not recording vocals), or if you have a way of externally processing inputs, choose a higher buffer size.

Depending on your computer's CPU speed, you might find that settings in the middle work best (256 to 1024).

Transport responsiveness

Buffer size also impacts how quickly your audio software will respond when you begin playback, although not by amounts that are very noticeable. Lowering the buffer size will make your software respond faster; raising the buffer size will make it a little bit slower, but barely enough to notice.

Effects processing and automated mixing

Reducing latency with the buffer size setting has another benefit: it lets you route live inputs through the real-time effects processing and mix automation of your audio software.

CUEMIX FX HARDWARE MONITORING

The MicroBook has a more direct method of patching audio through the system. This method employs the MicroBook's CueMix FX digital mixer. When enabled, CueMix FX activates hardware patch-thru in the MicroBook itself. CueMix FX has two important benefits:

- It completely eliminates the patch thru delay (reducing it to a small number of samples — about the same amount as one of today's advanced digital mixers).

■ CueMix FX imposes no strain on the computer.

The trade-off, however, is that CueMix FX bypasses your host audio software. Instead, live audio inputs are patched directly through to outputs in the MicroBook itself and are mixed with disk tracks playing back from your audio software. This means that you cannot apply host-based plug-ins, mix automation, or other real-time effects that your audio software provides. But for inputs that don't need these types of features, CueMix FX is the way to go.

On the other hand, if you really need to use the mixing and processing provided by your audio software, you should not use CueMix FX. Instead, reduce latency with the buffer setting (as explained earlier in this chapter).

Using CueMix FX

The CueMix FX software manages your monitor mix and runs side-by-side with your host audio software.

CueMix FX allows you to create up to four separate MicroBook stereo mixes, or any other desired routing configurations. These routings are independent of your host audio software. For complete details, see chapter 7, “CueMix FX” (page 37).

CHAPTER 6 Windows Audio Software

CLOCK SOURCE

Some host software may have a “clock source” setting. For the MicroBook, there is only one choice for clock source: Internal.

INPUTS AND OUTPUTS

Once you've enabled the MicroBook's driver, MicroBook audio inputs and outputs will appear in your host software wherever audio inputs and outputs are listed.

WORKING WITH CUEMIX FX MIXING AND EFFECTS

The MicroBook provides powerful external mixing, EQ and compression, which you can operate hand-in-hand with your host software's complete mixing environment. For example, the MicroBook can serve as a monitor mixer routing channels to musicians, or it can serve as an integrated extension of your digital audio workstation's mixing environment. If you program a MicroBook mixing and processing configuration that goes hand in hand with your digital audio workstation's project, be sure to use the file save features in CueMix FX to save the

MicroBook settings as a file in the same folder as your digital audio workstation's project file for instant recall of all settings. See chapter 7, "CueMix FX" (page 37) for complete details.

24-BIT OPERATION

Your MicroBook hardware fully supports 24-bit recording capabilities. Simply enable 24-bit operation as instructed in your digital audio workstation's manual. The MicroBook always supplies a 24-bit data stream.

CHAPTER 7 CueMix FX

OVERVIEW

AN 8-BUS MIXER WITH EQ AND COMPRESSION

All MicroBook inputs and outputs can be mixed and controlled by the on-board CueMix FX 8-bus (4 stereo bus) digital mixer driven by hardware-based DSP.

The CueMix FX mixer allows you to apply no-latency EQ and dynamics to inputs and outputs directly in the MicroBook hardware, independent of the computer. Input signals to the computer can be recorded wet, dry, or dry with a wet monitor mix (for musicians during recording, for example).

Effects include:

■ 7-band parametric EQ modeled after British analog console EQs

■ A standard compressor with conventional threshold, ratio, attack, release, and gain controls

The MicroBook's flexible effects architecture allows you to apply seven bands of EQ and compression on every input and output simultaneously.

CueMix FX provides several major advantages over mixing and processing in your host audio software:

- CueMix FX has no buffer latency. Thanks to the MicroBook’s DSP chip, CueMix FX provides the same throughput performance as a digital mixer.

- CueMix FX mixing and effects processing imposes no processor drain on the computer's CPU.

■ CueMix FX routing can be maintained independently of individual software applications or projects.

CueMix FX is installed with the rest of your MicroBook software.

Here is a brief overview of the CueMix FX mixer.

Four stereo mix busses

CueMix FX provides four stereo mix busses: Mix 1, Mix 2, Mix 3, and Mix 4. Each mix bus can take any number of inputs and mix them together into a

single stereo audio stream that you can then assign to any MicroBook output pair — or combination of output pairs — that you choose. For example, Mix 1 could go to the headphones, Mix 2 could go to the main outs, Mix 3 could go to a piece of outboard gear connected to analog outputs 3-4, and so on. You can also assign a mix to multiple output pairs. For example, you could assign Mix 1 to the Main Out, Phones, and Line Out.

Figure 7-1: CueMix FX is a virtual mixer that gives you control over the MicroBook's on-board mixing features.

Viewing one mix bus at a time

CueMix FX displays one mix bus at a time in the Mixes tab (Figure 7-1 on page 38). To select which mix you are viewing, choose it from the mix bus menu. The mix name appears above the mix bus master fader, where you can click the name to change it.

Each mix bus is independent

Each mix bus has its own settings. Settings for one bus will not affect another. For example, if an input is used for one bus, it will still be available for other busses. In addition, inputs can have a different volume, pan, mute and solo setting in each bus.

Input channels

The Inputs tab (Figure 7-2 on page 40) gives you access to settings for individual MicroBook inputs (or input pairs), such as phase, trim, EQ and dynamics processing. These settings are applied to the signal before it goes anywhere else (to a mix bus or the computer).

Output channels

The Outputs tab (Figure 7-4 on page 42) gives you access to settings for each MicroBook output pair, including EQ and dynamics processing. These settings are applied to the signal just before it is sent to the output.

Channel focus and settings

Click the focus button for a channel (Figure 7-1) to view channel-specific parameters in the Channel Settings section of the CueMix FX window (Figure 7-1). Separate tabs are provided for channel-specific settings (channel strip, EQ and dynamics), plus the global meter bridge and signal generator.

Output volume controls

The Output volume controls(Figure 7-1) provide independent volume control for all of the MicroBook's outputs.

Other features

CueMix FX offers many additional features, such as extensive metering, graphic editing of certain effects parameters, and more. For complete information, refer to the CueMix FX PDF manual, which is placed on your hard drive by the MicroBook installer.

Widening the CueMix FX window

To view more input faders at once, resize the window.

THE INPUTS TAB

Click the Inputs tab (Figure 7-2) to access and control all of these input channel settings for each MicroBook input or

input pair. Use the Focus button (Figure 7-2) to access the Channel, EQ, and dynamics tab settings for each input.

THE MIXES TAB

Click the Mixes tab (Figure 7-3) to gain access to the MicroBook's four stereo mix busses. The Mixes tab displays one mix bus at a time: choose each mix from the Mix bus menu in the tab itself. Each fader represents an input to the mix, except the fader on the right, which is the master fader for the mix. To assign each mix to a MicroBook output, visit the Outputs tab.

Aux 1-2

Inputs consist of physical inputs on the MicroBook interface (mic, guitar, etc.), but there is also a stereo input channel for Aux 1-2. This is audio being routed to the MicroBook from your host audio software. By bringing up this fader, you can combine live inputs (mic, guitar, and line 1-2) with any audio from the computer.

Stereo grouping

The input channel strips in the Mixes tab can represent either a mono input channel or a stereo pair. For the line inputs, this is controlled by their grouping in the Inputs tab, using the Mono/Stereo buttons in the channel strips for the line inputs (Figure 7-2).

Figure 7-3: The Mixes tab.

THE OUTPUTS TAB

The Outputs tab (Figure 7-4) lets you apply EQ and dynamics to any output pair, just before the signal leaves the MicroBook. This is processing that occurs at the very end of the signal flow, after everything else (host based effects, MicroBook input or bus processing, mixing, and so on). Processing is done in the digital domain, just before the signal goes analog through the D/A converter. Output tab processing is applied to the entire output mix (all signals being mixed to the output from various sources).

Signal flows from top to bottom

Settings in each Output tab channel strip are applied to the signal in order from top to bottom. For example, EQ occurs before Dynamics.

Output channel focus

Click the channel focus button (Figure 7-4) to view and edit parameters, such as EQ and dynamics, in the Output Settings section of the CueMix FX window.

Output source

Choose the Source for the audio output. The source can be a mix bus (which can have multiple sources itself) or the MicroBook's signal generator.

SCOPE/RETURN CHANNELS

Choose Devices menu> MicroBook> Setup to access the Scope/Return Channel Selection settings below (Figure 7-7). The MicroBook sends two extra return channels to the host audio software running on your computer. This window lets you control the audio source for each channel and whether or not the signal will be processed with the MicroBook EQ and/or Dynamics processing settings via the Pre/post effects menu.

Note that you can route entire mix busses, and even MicroBook output signals, back to the computer.

Figure 7-7: MicroBook Device Setup.

Return channels

The source for the Return 1 and Return 2 channels in your host audio software (provided by the MicroBook Core Audio and ASIO driver) are determined by Scope/Return channel settings (Figure 7-7).

For example, if you want to mix inputs with effects and send the result to MicroBook outputs, but you also want to send those same inputs dry (no processing) to the host, then select those inputs in the Scope/Return menus and choose Return 1 and/or Return 2 as the input to your host software.

Scope channels

The CueMix FX tuner and audio analysis (scoping) features described on the next few pages always look at the two Scope/Return channels (Figure 7-7).

TUNER

The Tuner window is an accurate and easy to use tuner. Choose the Tuner item from the Devices menu, under the MicroBook. The Tuner follows the currently chosen Scope/Return channels. The displayed channel pair is shown in the lower left corner. Each channel has a check box to enable or disable its input to the tuner.

AUDIO ANALYSIS TOOLS

CueMix FX provides advanced audio analysis tools. This section gives a brief summary. For complete information, refer to the CueMix FX PDF manual, which is placed on your hard drive by the MicroBook installer.

FFT display

The Filter response display section in CueMix FX can display real-time FFT and spectrogram information.

Choose Show FFT from the Filter display options menu (Figure 7-8) to superimpose a real-time Fast Fourier Transform (FFT) frequency measurement curve over the EQ filter display, as show below:

Figure 7-8: FFT display. Make sure that the Scope Channels (Figure 7-7) match the channels that are currently in focus via the Focus buttons (Figure 7-1).

The FFT curve is post-filter. Therefore, the FFT shows the results of the EQ filter(s) being applied.

Spectrogram

Choose Options menu> Show Spectrogram (Figure 7-8) to superimpose a real-time spectrogram “waterfall” display in the EQ display background:

Outputs: Analog 1-2

Figure 7-9: Spectrogram display.

X-Y Plot

The X-Y Plot window (Figure 7-10) graphs the amplitude of a stereo audio signal on a two-dimensional grid. To open the X-Y Plot, choose it from the Devices menu.

Figure 7-10: X-Y Plot.

For each unit of time (i.e. each sample), the amplitude of the left channel is displayed on the x-axis and the amplitude of the right channel is displayed on the y-axis. A thick white vertical line marks where left channel amplitude equals zero; a thick white horizontal line marks where

right channel amplitude equals zero (Figure 7-10, below). There are also thick white diagonal lines for y = x and y = -x.

Phase Analysis

To open the Phase Analysis window (Figure 7-11), choose it from the Devices menu. Phase Analysis graphs frequency versus phase difference versus amplitude of a stereo signal on either rectangular or polar coordinates.

In rectangular coordinates, the vertical axis represents frequency, and the horizontal axis represents the phase of the left channel minus the phase of the right channel (measured in radians).

In polar coordinates, the radius represents frequency and the angle (theta) from the +y vertical axis represents the phase difference of left channel minus the right channel.

APPENDIX A Troubleshooting

AudioDesk authorization doesn't succeed When authorizing AudioDesk, the OK button does not become active until you have entered in your name and a valid keycode. Your name must contain at least 3 characters, and you must enter the keycode provided with your AudioDesk installer disc. Additionally, the AudioDesk installer disc must be inserted.

Clicks and pops due to hard drive problems

You may have a drive related problem. Try recording just using the analog inputs and outputs of the MicroBook. If you encounter the same artifacts you may want try using another drive in your computer. Clicks and pops can also occur when the drive is severely fragmented, the disk drivers are outdated, or other drive-related issues. If you are using a USB hard drive on the same bus as the MicroBook, it could be that the USB bus is overloaded (too many devices on the same bus). Try removing all devices except the MicroBook.

Connecting or powering gear during operation

It is not recommended that you connect/disconnect, or power on or off devices connected to the MicroBook while recording or playing back audio. Doing so may cause a brief glitch in the audio.

Monitoring - How to monitor inputs?

Please refer to the documentation for the audio application that you are using. If your application does not support input monitoring, you will need to use the MicroBook's hardware-based CueMix FX monitoring feature. Please see chapter 7, "CueMix FX" (page 37).

Controlling monitoring latency

See chapter 7, "CueMix FX" (page 37).
