WINDOWS USERS: INSTALL THE SOFTWARE FIRST
If you are using the MicroBook with a Windows computer, installation goes much more smoothly if you install the MicroBook software before you connect the MicroBook hardware. Proceed to chapter 4,“Installing the MicroBook Software” (page 21) first, and then return to this chapter to then proceed with the hardware installation.
CONNECT THE MICROBOOK INTERFACE
1 PlugtheMicroBookUSBcable (included) into a USB socket on the computer as shown below in Figure 3-1.
2 PlugtheotherendoftheUSBcable into the MicroBook as shown in Figure 3-1.
Figure 3-1: Connecting the MicroBook to the computer.
INSTALLING THE MICROBOOK HARDWARE 15
CONNECT AUDIO INPUTS AND OUTPUTS
Here are a few things you should keep in mind as you are making input and output connections to other devices.
Mic input with preamp
Connect a dynamic or condenser microphone to the mic input (Figure 3-2) with a standard mic cable. If the cable has a quarter-inch plug, connect it directly. If it has a male XLR plug, use the female- XLR-to-quarter-inch adapter included with the MicroBook.
☛ The mic cable adapter supplied with the MicroBook is wired specifically for the MicroBook mic input, so do not use a substitute, unless you are certain it is wired as shown in Appendix B,“Mic Adapter Pin-outs” page (51).
☛ Do not connect a +4 (line level) input to the mic input (because it will overdrive the preamp).
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 MicroBook’s CueMix FX software (Figure 3-4). See “Input settings” on page 17.
Figure 3-2: MicroBook front panel
☛ 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. Never enable 48V power when a tip/sleeve (unbalanced) plug is connected to the mic input.
20 dB pad
If the input signal is still too hot with the trim turned all the way down, engage the 20dB pad button in the CueMix FX Channel tab (Figure 3-4). See “Input settings” on page 17.
Plug in your guitar to the guitar input (Figure 3-2). For ultra-realistic sound and feel when producing guitar tones with virtual guitar 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 3-3) are balanced (TRS) connectors that can also accept an unbalanced plug. Alternately, you can use
16 INSTALLING THE MICROBOOK HARDWARE
the eighth-inch stereo mini plug for line level input (from an iPod or other source).
☛ 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.
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. You can adjust the trim level for each input in the MicroBook’s CueMix FX software. See “Input settings” on page 17.
Input metering while adjusting trim
In the CueMix FX software, use the long- throw, horizontal input level meter at the top of the channel settings section (Figure 3-4) to calibrate the level.
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 ClicktheInputstab(asshownon page 7).
Figure 3-3: MicroBook back panel
2 Click the Focus button for the desired input channel.
3 ClicktheChanneltab(Figure3-4)to access the channel’s input settings.
Figure 3-4: Input settings in CueMix FX.
In a standard studio configuration, the main outs (Figure 3-3) 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.
You can use the eighth-inch stereo mini line out jack for output to desktop speakers or any other line level destination.
INSTALLING THE MICROBOOK HARDWARE 17
The S/PDIF RCA “digital out” connector provides stereo digital audio output to another device: the S/PDIF output always mirrors the Main Outs.
Bus power requirements
The MicroBook draws all the power it needs from the USB bus 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
Here are a few typical examples of bus- powered MicroBook 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. For extended recording sessions, bring extra, fully charged laptop batteries.
18 INSTALLING THE MICROBOOK HARDWARE
A TYPICAL MICROBOOK SETUP
Here is a typical MicroBook studio setup. This rig can be operated without an external mixer.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 CueMixTM 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.

CHAPTER 4 Installing the MicroBook Software
To install the MicroBook software:
1 InserttheMOTUUniversalInstaller disc and launch the installer.
2 Followthedirectionsthattheinstaller 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.
WINDOWS SOFTWARE INSTALLATION
Before you connect the MicroBook audio interface to your PC and turn it on, insert the MOTU Audio installer disc and run the MicroBook Installer. This ensures that all the MicroBook components are properly installed in your system.
If Windows asks you to locate the drivers
If you’ve already connected the
MicroBook to your computer and switched it on, 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:
as instructed in the next section.

MAC OS X AUDIO SOFTWARE
Choose the desired overall sample rate for the MicroBook system and your host software. Newly recorded audio will have this sample rate.
Some host software may have a “clock source” setting. For the MicroBook, there isonlyonechoiceforclocksource: Internal.
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 chapter 7,“Reducing Monitoring Latency” (page 33).
WORKING WITH CUEMIX FX MIXING AND EFFECTS
The MicroBook provides powerful external mixing, EQ and compression, which you can operate hand-in-hand withyourhost’smixingenvironment.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 39) for complete details.
☛ In Digital Performer, you can set up your MicroBook configuration file as a DP startup clipping so that it automatically loads when you open the project. Refer to the Digital Performer User Guide for details.
YourMicroBookhardwarefullysupports 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:
2 Via the MicroBook CueMix FX
Figure 5-11 below shows method #1, which allows you to apply host-based effects processing via plug-ins in your audio software. See the next section,
1. Live input (from mic, guitar, etc.) enters the MicroBook.
2. Mic signal goes immediately to the computer.
Figure 5-11: 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.
“Adjusting the audio I/O buffer” for details about how to reduce or eliminate the audible monitoring delay that the computer introduces.
Figure 5-12 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
3. Mic signal is ‘patched thru’ back to the audio interface with host-based plug-in effects, if any.
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).
MAC OS X AUDIO SOFTWARE
“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 5-11 and Figure 5-12) 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
1. Live input (from mic, guitar, etc.) enters the MicroBook.
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.
3. Mic signal is mixed to the main outs, and you can control the volume (relative to the rest of the mix) with the mic’s fader in CueMix FX.
2. 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 5-12: 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.
MAC OS X AUDIO SOFTWARE 29
Under Mac 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 23).
Figure 5-14: In Cubase or Nuendo, choose Devices menu> Device Setup and select the MicroBook to access the window above and the Audio Buffer Size setting (via the Control Panel button).
Figure5-13:In Digital Performer and AudioDesk, choose Setup menu> Configure Audio System> Configure Hardware Driver to open the dialog shown above and access the Buffer Size setting. Refer to your Digital Performer or AudioDesk user guide for infor- mation about the Host Buffer Multiplier setting.
Figure 5-15: In Logic Pro or Logic Express, go to the Audio Driver preferences to access the I/O Buffer Size option shown above.

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.
Figure 5-16: When adjusting the buffer size to reduce monitoring latency, watch the ‘processor’ 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).
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:
MAC OS X AUDIO SOFTWARE
■ 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 five 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 39).
