Sample rate
Choose the desired overall sample rate for the
UltraLite-mk3 system and AudioDesk. Newly
recorded audio in AudioDesk will have this sample
rate. Imported audio or soundbites in existing files
that do not match this sample rate will be displayed
in the Soundbites window with a red 'X' on its
move handle to indicate that it cannot be played.
Clock Source
This setting is very important because it
determines which audio clock the UltraLite-mk3
will follow.
If you do not have any digital audio connections to
your UltraLite-mk3 (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 a S/PDIF digital audio device
connected to the UltraLite-mk3, see "Connecting
and syncing S/PDIF devices" on page 22.
If you are slaving the UltraLite-mk3 and
AudioDesk to SMPTE time code via the
UltraLite-mk3 itself, choose SMPTE and follow the
directions in "Resolving DP or AudioDesk to
SMPTE time code" on page 111.
Buffer Size
The Buffer Size setting can be used to reduce the
delay — or monitoring latency — that you hear
when live audio is patched through your
UltraLite-mk3 hardware and AudioDesk. For
example, you might have MIDI instruments,
samplers, microphones, and so on connected to
the analog inputs of the UltraLite-mk3. If so, you
will often be mixing their live input with audio
material recorded in AudioDesk. See chapter 10,
"Reducing Monitoring Latency" (page 61) for
complete details.

Phones
This UltraLite-mk3 setting lets you choose what
you'll hear from the headphone jack. For example,
if you choose Main Out 1-2, the headphones will
duplicate the main outs. Or you can choose any
other output pair. If you choose Phones, this setting
makes the headphone jack serve as its own
independent output pair. As a result, you'll see
Phones 1-2 as an additional audio destination in
AudioDesk's audio output menus.
Main Outs Assign
Use the Main Outs Assign setting to determine
what audio you will hear on the TRS main outs of
the UltraLite-mk3. If you would like to treat them
as their own separate output pair, choose Main
Outs.
Return Assign
In AudioDesk's audio input menus and the Bundles
window, you'll see an UltraLite-mk3 input called
Return 1-2 (Figure 8-2). This is a stereo feed from
the UltraLite-mk3 that matches the output of one
of its output pairs. Use the Return Assign menu in
MOTU Audio Setup to choose which output pair
you would like to hear on this return. This can be
used, for example, to record back a final stereo mix
that includes effects processing from the
UltraLite-mk3 DSP (such as the Leveler) for
reference and archiving purposes.

UltraLite-mk3 in AudioDesk's Bundles window.
