With a variety of I/O formats, mic preamps, nolatency mixing and processing of live input and synchronization capabilities, the Track16 is a complete, portable “studio in a box” when used with a Mac or Windows computer. Mic inputs Both mic inputs are equipped with a separate preamp. Individual 48V phantom power and 20 dB pad are supplied by the top panel switches. Each input can be trimmed with the volume knob.
Optical The optical connectors provide 8 channels of ADAT optical at 44.1 or 48 kHz, 4 channels of S/MUX optical I/O at 96 kHz or stereo TOSLINK at rates up to 96 kHz. The banks operate independently, allowing you to mix and match any optical formats on input and output. For example, you could receive 4 channels of 96 kHz S/MUX input while at the same time sending 96 kHz stereo optical S/PDIF (“TOSLINK”) output.
16-BIT AND 24-BIT RECORDING The Track16 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 Track16’s analog or digital inputs and outputs. 24-bit audio files can be recorded with any compatible host application that supports 24-bit recording.
CueMix FX provides attractive graphic mixing, graphic editing of parametric EQ and a convenient tabbed interface for quick access to all mixing features, digitally controlled trims and other settings in your MOTU audio interface.

Track16 tab settings The Track16 tab (Figure 5-1) provides settings that apply to a specific Track16 interface. If you have several Track16 (or other MOTU) interfaces connected, you’ll see a separate tab for each one. General tab settings The General tab (Figure 5-1) provides settings that apply to all connected MOTU FireWire and USB Audio interfaces. ‘TRACK16’ TAB SETTINGS Enable Core Audio Volume Controls Under Mac OS X 10.
Clock Source The Clock Source determines the digital audio clock that the Track16 will use as its time base. The following sections briefly discuss each clock source setting. Internal Use the Internal setting when you want the Track16 to operate under its own digital audio clock. For example, you may be in a situation where all you are doing is playing tracks off hard disk in your digital audio software on the computer.
output, which you can access as an independent output destination in your host audio software and as an output destination for the four on-board CueMix FX mix busses. Optical input/output The Optical input and Optical output settings let you choose between 8-channel ADAT optical (‘lightpipe’) and stereo S/PDIF optical (‘TOSLINK’) as the format for the Track16’s optical input and output. Choose the format that matches the device connected.
As another example, you could use the stereo return bus to capture tracks played from your host software, along with live inputs being routed directly through the Track16 hardware via CueMix FX (with or without CueMix effects processing on the live inputs). ‘GENERAL’ TAB SETTINGS Launch MOTU Audio Setup when hardware becomes available Check this option if you would like the MOTU Audio Setup icon to appear in the application dock as soon as a MOTU interface is detected (powered on, plugged in, etc.

CHAPTER 7 Configuring Host Audio Software OVERVIEW The Track16 provides multi-channel audio input and output for Core Audio-compatible audio applications, including MOTU’s Digital Performer and AudioDesk, Apple’s Logic Pro, Logic Express, SoundTrack Pro, and GarageBand, and other third-party software applications such as Ableton Live, Avid Pro Tools, Cockos Reaper, Propellerhead Reason and Record, Steinberg Cubase and Nuendo, and others. AudioDesk is included with your Track16 system.
If you do not have any digital audio connections to your Track16 (you are using the analog inputs and outputs only), and you will not be slaving your host software to external SMPTE time code, choose Internal. If you have devices connected to the Track16 optical ports, see “Choosing a clock source for optical connections” on page 27. If you are slaving the Track16 and your host software to SMPTE time code, follow the directions in chapter 10, “MOTU SMPTE Setup” (page 103).

outputs, check MOTU Audio Setup to make sure they are enabled. If you don’t plan to use either optical bank, turn it off to conserve computer bandwidth. Remember that the main outs and headphone output can be configured in MOTU Audio Setup to mirror other outputs. In addition, the Track16 optical banks can be disabled or configured as either ADAT optical or TOSLink. This will affect how they appear (and if they appear at all) in your host software’s audio input lists.
SYNCHRONIZATION You may encounter situations in which you need to synchronize your audio software and the Track16 to the other components of your system. Synchronizing digital audio connections If you have devices connected to the Track16 digital optical ports, you need to be concerned with the synchronization of the Track16’s digital audio clock with other devices connected to it digitally (if any).
CONFIGURING HOST AUDIO SOFTWARE
CHAPTER 8 Reducing Monitoring Latency OVERVIEW Monitoring latency is that slight delay you hear when you run an input signal through your host audio software. For example, you might hear it when you drive a live guitar input signal through an amp modeling plug-in running in your audio sequencer.
MONITORING LIVE INPUT There are two ways to monitor live audio input with an Track16: 1) through the computer or 2) via the Track16 CueMix FX hardware mixer. Figure 8-1 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 — and possibly eliminate — the audible monitoring delay that the computer introduces.
ADJUSTING THE AUDIO I/O BUFFER A buffer is a small amount of computer memory used to hold data. For audio interfaces like the Track16, 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.
■ How responsive the transport controls are in AudioDesk, Digital Performer or other audio software Figure 8-4: In Cubase or Nuendo, choose Devices menu> Device Setup. Select MOTU Track16, then click the Control Panel button to access the window above and the Buffer Size setting. 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.
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 Track16 has a more direct method of patching audio through the system: CueMix FX. CueMix FX is a digital mixer in the Track16 hardware itself.
Controlling CueMix FX from within AudioDesk or Digital Performer To turn on CueMix FX in AudioDesk and Digital Performer: 1 From the Setup menu, choose Configure Audio System> Input Monitoring Mode. 2 Choose the Direct hardware playthrough option, as shown below in Figure 8-7. 3 From the Studio menu, choose Audio Patch Thru, and choose any monitoring mode except Off. Figure 8-7: Enabling CueMix FX in AudioDesk or Digital Performer.
CHAPTER 9 CueMix FX OVERVIEW CueMix FX is a cross-platform software application that provides graphic, on-screen control for the Track16’s flexible CueMix FX on-board mixer and effects processing. CueMix FX also provides many advanced audio analysis tools, including a tuner and oscilloscope. CueMix FX can be used independently of host audio software, or together with it. CueMix dovetails with the direct monitoring features of your host audio software, allowing you to seemlessly mix in both environments.
ADVANTAGES OVER HOST-BASED MIXING AND PROCESSING CueMix FX provides several major advantages over mixing and processing in your host audio software: ■ CueMix has no buffer latency. Thanks to the Track16’s DSP chip, CueMix provides the same throughput performance as a digital mixer. ■ CueMix mixing and effects processing imposes no processor drain on the computer’s CPU. ■ CueMix routing can be maintained independently of individual software applications or projects.
Output channels The Outputs tab (Figure 9-6 on page 65) gives you access to settings for each Track16 output pair, including EQ, dynamics processing and send/ return controls for feeding and returning the output signal to/from the Track16’s global reverb processor. These settings are applied to the signal just before it is sent to the output.
THE MIXES TAB Click the Mixes tab (Figure 9-2) to gain access to the Track16’s eight stereo mix busses. The Mixes tab displays one mix bus at a time. Viewing a mix Choose the mix you wish to view from the mix bus menu (in the Mixes tab itself, as shown in Figure 9-2). The menu shows all mixes by name, followed by the Track16 output pair to which each bus master fader is assigned.
Bus reverb send/return The bus reverb send (Figure 9-2) feeds the output of the mix bus, pre-fader, to the Track16’s global reverb processor, where it is merged with any other signals being fed to the reverb. The reverb’s output can then be fed back into the mixer at various return points, including the bus return (discussed below). The bus reverb return (Figure 9-2) feeds the output of the Track16’s global reverb processor into the mix bus, pre-fader.
THE INPUTS TAB The Track16 provides many features for managing analog and digital input signals. Some of these features, such as the Track16’s digitally controlled analog trims, are implemented in the analog domain; others are implemented in the digital domain as DSP applied to the digital signal (after the A/D converter on analog inputs). Click the Inputs tab (Figure 9-3) to access and control all of these input channel settings for each Track16 input or input pair.
Input channel focus Click the channel focus button (Figure 9-3) to view and edit parameters in the channel settings section of the CueMix FX window (Figure 9-7 on page 66). Input EQ and dynamics The Track16 lets you apply 7-band parametric EQ and dynamics processing (DSP) to any input, analog or digital. Mono/stereo pairing Click the Mono button (Figure 9-3) if you would like an input to be treated as a mono channel.

Compressor graph Compressor meter Compressor selector EQ/Dynamics enable/disable buttons Click the EQ or Dynamics button at the bottom of the input channel (Figure 9-3) to toggle the effect on or off.
Output channel focus Click the channel focus button (Figure 9-6) to view and edit parameters in the channel settings section of the CueMix FX window (Figure 9-7 on page 66). Channel focus also determines which channels are being scoped by CueMix’s audio analysis tools, as explained in “Choosing channels for audio analysis” on page 82. Output EQ and Dynamics The EQ/Dynamics section in the Outputs tab (Figure 9-6) works identically to the EQ/Dynamics section for the Inputs tab (Figure 9-3).
THE CHANNEL SETTINGS SECTION The channel settings section in the CueMix FX window (Figure 9-1) displays three tabs for Channel, EQ and Dynamics settings for the channel with the current focus. There are also two global tabs: the Meter Bridge and the Reverb Processor, as shown below. The Channel tab The Channel tab (Figure 9-8) displays settings for input channels. Click any focus button in the Inputs tab to view the Channel tab settings for the channel. Figure 9-8: The Channel tab.
Stereo settings Inputs that have been grouped as stereo pairs in the Inputs tab (Figure 9-3) provide two stereo modes (Figure 9-8): Normal and M/S. M/S mode provides decoding for a mid-side microphone configuration. The Width knob (Figure 9-8) provides control over the stereo imaging, going from a full stereo image to mono (both channels panned equally). See “Width” on page 61. The Swap L/R button (Figure 9-8) lets you switch the left and right channels.
The EQ tab The EQ tab (Figure 9-10) displays the EQ settings for the input or output channel that currently has the focus. Click any focus button in the Inputs or Outputs tab to view the EQ tab settings for the channel. Vintage EQ Inspired by legendary British large console EQs, the Track16 Vintage EQ section (Figure 9-10) gives you the look, feel and sound of the most soughtafter classic equalizers.

Type I Type II Figure 9-13: Type I EQ filter style. Figure 9-14: Type II EQ filter style. The Type I EQ filter has the least amount of Gain/Q interaction, providing the most precision and control of all the EQ filter types. Even small adjustments in gain or reduction produce relatively high Q. This EQ style is best for situations that call for precise EQ adjustments requiring the maximum amount of individual parameter control. For more general shaping (e.g. full mixes) or subtle control (e.g.
Type III Type IV Figure 9-15: Type III EQ filter style. Figure 9-16: Type IV EQ filter style. The Type III EQ filter increases Q as boost is applied. Therefore, lower amounts of boost provide a softer, “wider” EQ effect (since the affected frequency range widens), while higher boost tends to sound louder and more “up front”, due to the increase in Q as the gain is increased.
Shelf filters response corresponds to a second order shelf, still with no overshoot. This is the same response as conventional parametric EQs. In some situations, this form of accurate, clean shelving can sound harsh, especially when compared to legacy analog EQs. To soften the results, the overshoot is increased as Q is increased, as shown Figure 9-17 for Q values of 1.00, 2.00 and 3.00.
Overshoot tends to produce more of what one would expect to hear when applying shelving and is therefore considered to be more musical than shelving without overshoot. This effect, which has gained tremendous popularity among audio engineers, was first made popular in original Neve series EQs and later in the SSL G series. At maximum the maximum Q setting of 3.00, the overshoot peaks at half the total boosted (or cut) gain.
Compressor The Compressor (Figure 9-21) lowers the level of the input when it is above the threshold. The amount of attenuation is determined by the Ratio and the input level. If the input is 6 dB above the Threshold and the Ratio is 3:1, then the output will be 2 dB above the Threshold. When the input level goes above the threshold, the attenuation is added gradually to reduce distortion. The rate at which the attenuation is added is determined by the Attack parameter.
mounted so that the emission of the panel modulates the resistance. An ELP consists of a thin layer of phosphorescent material sandwiched between two insulated electrodes to form a capacitor. Making one of the electrodes transparent allows the light to escape. These devices are essentially glow-in-the-dark paint on a piece of foil covered by metalized glass or plastic, and are the same devices used in low-power night lights.
The Meters tab The Meters tab (Figure 9-22) serves as a comprehensive meter bridge for all inputs, outputs and mix busses in the Track16. This tab gives you a “bird’s-eye” view of all signal activity in the Track16; it is ideal for confirming your signal routing programming and for troubleshooting. Bus activity LEDs (inputs only) Channel meter display displaying an input meter).
Routing inputs, busses and outputs to the reverb processor The reverb processor is a single, independent unit that provides stereo reverb.You can route multiple signals to it from various points (sends) in the CueMix FX mixer, but all incoming signals to the reverb processor are merged and processed together. The resulting stereo output from the reverb can then be inserted into a mix bus or output using stereo returns.
types of spaces. The Size and Level parameters let you control the size of the room and the strength of the initial reflections. ☛ Here’s a tip: try using initial reflections without any subsequent reverb (turn the reverb time down as far as it will go). You’ll hear interesting and unusual effects. Reverb design The Reverb Design section allows you to independently control the reverb time for three separate frequency bands (Low, Mid and High) with adjustable cross-over points between them (Low and High).

Choose any device from the menu to edit its settings using the CueMix FX software.
FFT AND SPECTROGRAM DISPLAY FFT and spectrogram information can be displayed in the Filter response display section in the EQ tab (Figure 9-10 on page 68) or as a separate window (Figure 9-28 on page 83) opened from the Devices menu (Figure 9-26).
☛ “Show EQ Controls” will be available only if the focused pair are a stereo input pair or stereo output pair. Figure 9-30: FFT display. The spectrogram scrolls from top to bottom, where the top edge of the display represents what you are hearing “now”. Color represents amplitude along the left/right frequency spectrum.
In Zoom/Offset mode, Zoom sets the display zoom from 1x to 100x, where the number represents the zoom factor relative to the entire frequency range. For example, when the horizontal zoom value is 1x, the entire frequency range from 10 to 24000 Hertz is displayed; when the horizontal zoom value is 2x, one half of the entire frequency range is displayed. Pos determines which frequency is displayed at the center of the graph.
Level meters are displayed to the right of the graph. One or two meters are shown, depending on the current view mode (see “View controls”). Opening the oscilloscope Each Track16 has its own oscilloscope. To open an oscilloscope, choose the Oscilloscope item from the Devices menu under the desired interface.

Time Units The Time Units sub-menu (Figure 9-37) provides the option to view the X axis in Seconds or Samples. Vertical controls (amplitude axis) The Vertical controls (Figure 9-37) operate similarly to the Horizontal controls, except that they configure the y-axis (amplitude). In Zoom/Offset mode, Zoom sets the display zoom from 1/2 to 100x, and Offset moves the line marking amplitude equals zero line up or down. In Min/Max mode, Min and Max set the smallest and largest displayed amplitude.
be enabled simultaneously. If neither is enabled, the criteria will not be found because the trigger is not looking for any particular kind of event. Trigger modes The Trigger menu (Figure 9-39 on page 87) provides four modes: The Level setting defines the amplitude threshold that the trigger is looking for. The Level is indicated on the graph by a blue horizontal line (or two blue horizontal lines, if Magnitude is enabled).
Trigger indicator re-arms the trigger. When the Trigger mode is None, clicking on the Trigger indicator has no effect. and the scientific note name. If the measured area is long enough, the approximate beats per minute (bpm) is displayed. Measurement information You can view detailed information about a particular time range by using the measurement bars. Ideas for using the Oscilloscope The Oscilloscope can be used in many useful ways during the routine operation of your recording studio.
adjustments to the compression plug-in’s settings, you can see the transient waveform change the next time the Oscilloscope triggers. For compression, this can be particularly useful for balancing the effect of the attack on the transient, relative to the decay portion of the waveform. Conversely, you can see the effect of the threshold setting directly on the decay portion, relative to the attack. In effect, you can see as well as hear the results of your compression adjustments.
Monitoring control voltage output from Volta MOTU’s Volta instrument plug-in for Mac OS X turns your audio interface into a control voltage interface, giving you precise digital control from your favorite audio workstation software of any hardware device with a control voltage (CV) input. The CV signals output from Volta can be monitored in the Oscilloscope, giving you visual feedback on LFOs, envelopes, ramps, step sequencers, and more.
Opening the X-Y Plot Each Track16 interface has its own X-Y Plot window. Choose the X-Y Plot item from the Devices menu under the desired interface. ☛ Choosing a channel pair to display The X-Y Plot follows the currently focused audio input or output. If you focus a mono channel (e.g. Analog 3), its corresponding stereo pair will be displayed (Analog 3–4).
In Min/Max mode, Min and Max let you scale the grid by moving the -1.0 and +1.0 points along the axis. Min/Max mode lets you control the graph boundaries directly. Using the X-Y Plot The X-Y Plot helps you “see” the width of the stereo field of a mix. It also helps you determine if a mix has issues with polarity, as follows: Persistence The Persistence controls (Figure 9-46) affect the appearance of data from when it is first displayed until it disappears from the grid.
PHASE ANALYSIS The Phase Analysis window (Figure 9-48 on page 94) 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). Choosing a channel pair to display The Phase Analysis window follows the currently focused audio input or output.
A/B (stereo audio channels) The View section (Figure 9-49) displays the pair of input or output audio channels you are viewing. See “Choosing a channel pair to display” above. Line/Scatter Choose either Line or Scatter from the menu in the View section (Figure 9-49) to plot each data point as either a single pixel or as a continuous line that connects each frequency data point to the next, as shown below in Figure 9-44.
Horizontal and vertical controls The Horizontal and Vertical controls (Figure 9-53) let you scale each axis of the grid and offset its zero point. Click and drag the values up or down to set them, or double-click to return to the default value. There are two modes for the controls: Zoom/Offset and Min/Max. To change the mode, use the menu shown in Figure 9-53. Figure 9-53: Setting the Horizontal or Vertical control modes. In Zoom/Offset mode, Zoom scales the axis. Pos moves the zero line.
outside the critical frequency range of the instrument being recorded, you can avoid phase problems among the mic signals. Tuning PA systems The Phase Analysis window can also be used to troubleshoot and tune PAs and sound reinforcement systems by placing microphones in strategic locations, comparing the two signals in the Phase Analysis grid and looking for phase issues at various locations.
TUNER The Tuner window is an accurate and easy to use tuner. Detected frequency Meter greater number of illuminated segments represents greater uncertainty. The color of the segments changes gradually from green (in tune) to yellow, orange, and red (progressively further out of tune). Meter value Meter value: difference between the detected note and the detected frequency, in cents.
CONFIGURATIONS MENU A configuration is just like a hardware preset (a “snapshot” of all settings in CueMix FX and therefore the Track16 hardware itself), except that it can be created and managed using the CueMix FX software on your computer, completely independently of the Track16 hardware. The commands in the Configurations menu let you create, save, load, import, export and otherwise manage as many configurations as you wish.
CONTROL SURFACES MENU CueMix FX can be controlled from an automated control surface such as the Mackie Control™. Use the commands in the Control Surfaces menu to enable and configure this feature. Application follows control surface When checked, the Application follows control surface menu command makes the CueMix FX window scroll to the channel you are currently adjusting with the control surface, if the channel is not visible when you begin adjusting it.
Other HUI-compatible control surfaces Any control surface that has the ability to emulate a HUI should be compatible with CueMix FX. Just add a Mackie HUI to Audio MIDI Setup and put the control surface hardware into HUI emulation mode. Consult the control surface manual for details about how put it into HUI emulation mode.

CHAPTER 10 MOTU SMPTE Setup OVERVIEW MOTU SMPTE SETUP The Track16 can resolve directly to SMPTE time code via any line input, without a separate synchronizer. The Track16 can also generate time code via its time code output. The Track16 provides a DSP-driven phase-lock engine with sophisticated filtering that provides fast lockup times and sub-frame accuracy. Direct time code synchronization is supported by AudioDesk and Digital Performer on Mac OS X.
detect and switch to the incoming frame rate, except that it cannot distinguish between 30 fps and 29.97 fps time code, or 23.976 and 24 fps time code. So if you are working with either of these rates, make sure you choose the correct rate from this menu. The Track16 driver updates the frame rate setting in Digital Performer and AudioDesk for you. Freewheel Address Freewheeling occurs when there is a glitch or drop-out in the incoming time code for some reason.
The Track16 cannot freewheel address without clock. Therefore, the Freewheel Address setting will always be lower than or equal to the Freewheel Clock setting, and both menus will update as needed, depending on what you choose. The ‘Infinite’ freewheel setting The Infinite freewheel setting in the Freewheel Clock menu causes the Track16 to freewheel indefinitely, until it receives readable time code again. To make it stop, click the Stop Freewheeling button.
SETUP FOR SMPTE TIME CODE SYNC Here is the basic setup to resolve the Track16 system directly to SMPTE time code. The Track16 can also generate time code, under its own clock or while slaving to time code. Therefore, the Track16 can act both as an audio interface and as a SMPTE time code synchronizer to which you can slave other devices.
RESOLVING DP OR AUDIODESK TO TIME CODE To resolve Digital Performer or AudioDesk directly to time code with no additional sync devices, use the setup shown in “Setup for SMPTE time code sync” on page 106. Choose Receive Sync from the Setup menu and choose the Sample accurate option. Make sure that the Slave to External Sync command in the Studio menu is checked. Make sure the Clock Source setting in the MOTU Audio Setup window is set to SMPTE.

Part 3 Appendices
APPENDIX A Audio I/O reference OVERVIEW The MOTU Audio drivers supply text string labels for the Track16’s audio inputs and outputs to clearly identify each one, but some applications do not display these labels. The following sections show how you can identify each input and output in a numbered list like this. Inputs at 1x sample rates Inputs are always listed in the same order as follows, when operating the Track16 at 1x sample rates (44.1 or 48 kHz): Input 44.
Outputs at 1x sample rates Outputs are always listed in the same order as follows, when operating the Track16 at 1x sample rates (44.1 or 48 kHz): Output 44.1/48 kHz Channels List position Comment Main out 2 1-2 - Phones 2 3-4 - Line 2 5-6 - Optical 8 ADAT 2 TOSLINK 7-14 7-8 - Outputs at 2x sample rates When operating the Track16 at a 2x sample rate (88.2 or 96 kHz), outputs are listed as follows: Output 88.
APPENDIX B Troubleshooting When I press the METERS button, all the other buttons change color. What’s going on? You have accidentally put the Track16 in Lockout mode, which lets you change the color scheme for the button LEDs. To exit this mode, hold down the METERS button for 2 seconds. To learn more about this mode, and how you can specify the color scheme you prefer, see “Lockout mode” and “Button LED color schemes” on page 42.
