2 Choose the desired 8pre mic input for the track.
3 Open the Audio Monitor window.
4 As you feed signal to the input, adjust the input’s
corresponding trim knob on the front panel of the
8pre until peaks in the level meter are as high as
possible without clipping (hitting zero dB).
WORKING WITH 8PRE INPUTS AND
OUTPUTS
Once you’ve enabled the MOTU FireWire Audio
driver as explained earlier in “The 8pre settings” on
page 35, 8pre audio inputs and outputs will appear
in AudioDesk’s audio input and output menus. If
you don’t see the optical inputs and/or outputs,
check MOTU Audio Setup to make sure they are
turned on. If you don’t plan to use the optical input
or output, turn it off to conserve computer
bandwidth.
Phones 1-2
If you’ve chosen to treat the 8pre headphones as an
independent output, you’ll see Phones 1-2 in
AudioDesk’s output menus. Audio tracks assigned
to this output pair will be heard on the headphone
jack only. For further explanation, see “Phones” on
page 36.
Mix1 1-2
In AudioDesk’s audio input menus, you’ll see an
8pre input called Mix1 1-2. This input source
delivers the output of CueMix DSP “MIX1” (the
first mix bus of the four on-board no-latency
monitor mixes in the 8pre) back to your computer.
This input serves, for example, as a convenient way
for you to record the 8pre’s MIX1 monitor mix
back into AudioDesk (for reference and archiving
purposes). Further, if you are sending audio from
AudioDesk to the same output pair as MIX1, you
can choose to either include or exclude the audio
from the computer in the stream being sent back to
AudioDesk. For details on how to do this, see
“Mix1 Return Includes Computer” on page 55.
☛ Warning: the Mix1 1-2 input can cause
feedback loops! DO NOT assign this input to a
track that shares the same 8pre output pair as
MIX1.
24-BIT OPERATION
Your 8pre hardware fully supports AudioDesk’s 24-
bit recording capabilities, including both analog
and digital 24-bit recording. If you would like to
record and play back 24-bit audio files, go to the
Setup menu, choose Configure Audio System>
Sample Format, and choose 24-bit recording as the
sample format. This setting is saved with the
AudioDesk project.
MIDI I/O VIA THE 8PRE MIDI PORTS
Once you’ve followed the procedure for enabling
the 8pre’s MIDI features as explained in “Software
installation for Mac OS X” on page 21, the 8pre
MIDI ports will appear as a input source and
output destination in AudioDesk’s MIDI I/O
menus.
PROCESSING LIVE INPUTS THROUGH
PLUG-INS
If you patch a live input (such as MIDI synthesizer)
through a plug-in effect in AudioDesk, you might
hear a slight delay. There are several ways to reduce
this delay. For details, see chapter 10, “Reducing
Monitoring Latency” (page 45).
SYNCING TO SMPTE TIME CODE
AudioDesk can run under its own transport
control or slave to SMPTE time code via the 8pre.
For details, see “Resolving DP or AudioDesk to
SMPTE time code” on page 63.
EXCHANGING PROJECTS WITH DIGITAL
PERFORMER
To open AudioDesk Version 2 (or Version 1) files in
Digital Performer, just use DP’s Open command.
(No conversion is required beforehand in
AudioDesk.) To export a Digital Performer project
to AudioDesk, use Save As in Digital Performer’s
