WORKING WITH ON-BOARD MIXING AND
EFFECTS
Your MOTU interface provides powerful mixing,
EQ, compression and reverb, which can operate
hand-in-hand with your host's mixing
environment. For example, your MOTU interface
can serve as a monitor mixer, routing channels to
musicians, or it can serve as an integrated
extension of your host's mixing environment. You
can even save a particular mixing configuration as
a preset for future recall. For details, see "Mixing
tab" on page 22.

SYNCHRONIZATION

You may encounter situations in which you need to
synchronize your audio software and your MOTU
interface to other components of your system. For
details, see "Synchronization" on page 58.

LTC-TO-MTC CONVERSION

When connected to a Mac, your MOTU interface
can convert SMPTE time code (LTC) to MIDI
Time Code (MTC), allowing any MTC-compatible
host audio software to resolve to MTC.
LTC-to-MTC conversion can be done even when
the Clock Mode setting for the MOTU interface is
set to Internal (or any other setting). Note that the
Clock Mode setting does NOT have to be set to
LTC. In other words, the interface can convert LTC
to MTC even when it is not resolving its audio
engine to the incoming time code. This allows your
DAW host software to resolve to time code with fast
lockup response.
To set up LTC-to-MTC conversion:
1 Set the interface Clock Mode to Internal (or any
other desired setting).
2 Set the other LTC settings as needed, as
discussed in "Syncing to SMPTE time code (LTC)"
on page 60, including the Computer Channel for
LTC-to-MTC Conversion setting.

3 If you would like MIDI Time Code to continue
to be generated, even after LTC stops being
received, check Enable Jam Sync (Figure 4-22 on
page 61). Otherwise, leave it unchecked.
4 Follow the directions for MTC (SMPTE) sync in
your DAW software.
Your MOTU interface driver automatically
communicates with OS X, creating a device in the
computer's Audio MIDI Setup configuration that
reports its time code port to any MTC-compatible
host software. If your host software requires that
you specify the port, you should see your MOTU
interface SMPTE Sync port as an available option
in the list. In Digital Performer, this is the Sync to
port menu in the Receive Sync settings (Setup
menu), which is set to Any by default (so it should
just work). Here's a summary for a few popular
DAW hosts:
