Streaming computer audio to and from the
on-board mixer
In Figure 7-6, you’ll see mixer inputs across the top
of the grid (Main, Monitor, Aux, etc.) These are
output buses from the UltraLite-mk4’s on-board
mixer. To route one of these mix buses to your host
computer software, click the grid at the
intersection of the mix column and desired
computer channel row. Now, the mix bus output
will be routed to the computer via the channel you
selected.
Conversely, you can stream audio from the
computer into the mixer. Channels coming from
the computer are represented across the top of the
routing grid as inputs. To route a computer channel
to the mixer, click the grid at the intersection of the
computer channel column and the desired mix
input row. Now, that computer channel will be
routed to the mixer input.
Mirroring computer channels to multiple
outputs
Figure 7-6 shows an example of mirroring one
stereo audio stream from host audio software to
several outputs. In the example, computer
channels 1-2 are being sent to Phones L-R and
Main L-R. To route a source to multiple
destinations, click multiple boxes in its column,
(see
From Computer
channels 1-2 in Figure 7-6).
Combining multiple sources to one output
To merge (mix) any channels in the grid (computer
streams or otherwise), route them to mixer inputs
and then use the on-board mixer (“Mixing tab” on
page 16).

WORKING WITH ON-BOARD MIXING AND
EFFECTS
the UltraLite-mk4 provides powerful mixing, EQ,
compression and reverb, which can operate hand-
in-hand with your host’s mixing environment. For
example, the UltraLite-mk4 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 16.
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:
6
Set the interface Clock Mode to Internal (or any
other desired setting).
7 Set the other LTC settings as needed, as
discussed in “Syncing to SMPTE time code (LTC)”
on page 35, including the
Computer Channel for
LTC-to-MTC Conversion setting.
8 If you would like MIDI Time Code to continue
to be generated, even after LTC stops being
received, check
Enable Jam Sync (Figure 4-5 on
page 36) . Otherwise, leave it unchecked.
