Warning: the Mix1 Return inputs can cause
feedback loops! DO NOT assign this input to a
track assigned to the Audio Express main outs.
For Mix1 Return 1-2, you can choose whether or
not to include audio being sent to the main outs
from the computer. See "Mix1 Return Includes
Computer Output" on page 62.
The "Phones 1-2" output
Host audio tracks assigned to the Phones 1-2
output pair will be heard on the headphone jack
only. If the Phones are set to mirror another output
(such as the main outs), the mirrored audio stream
is mixed with the phones audio output. For further
explanation, see "Phones Assign" on page 32.

24-BIT OPERATION

Your Audio Express hardware fully supports
Digital Performer'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, choose this as your preferred audio file
format in Digital Performer's Preferences.

MIDI I/O

Once you've followed the procedure for enabling
the Audio Express's MIDI features as explained in
"Software installation" on page 25, the Audio
Express MIDI ports will appear as a input source
and output destination in Digital Performer's
MIDI I/O menus.

PROCESSING LIVE INPUTS WITH PLUG-INS

If you patch a live input (such as MIDI synthesizer)
through a plug-in effect in Digital Performer, you
might hear a slight delay. There are several ways to
reduce this delay. For details, see chapter 10,
"Reducing Monitoring Latency" (page 51).

WORKING WITH CUEMIX FX MIXING

The Audio Express provides its own hardware-
based mixing, which you can operate hand-in-
hand with Digital Performer's complete mixing
environment. For example, the Audio Express can
serve as a monitor mixer routing channels to
musicians, or it can serve as an integrated
extension of your Digital Performer mixing
environment. If you program an Audio Express
mixing configuration that goes hand in hand with
your DP project, be sure to use the file save features
in CueMix FX to save the Audio Express settings as
a file in your DP project folder for instant recall of
all settings. See chapter 11, "CueMix FX" (page 57)
for complete details. You can even set up your
Audio Express configuration file as a DP startup
clipping so that it automatically loads when you
open the project. See your DP manual for details.

SYNCHRONIZATION

Together, Digital Performer and the Audio Express
have the ability to resolve directly to SMPTE time
code, without an additional time code
synchronizer. See "Syncing to SMPTE time code"
on page 84.

EXCHANGING PROJECTS WITH AUDIODESK

Digital Performer can exchange projects with
AudioDesk. To open an AudioDesk project in
Digital Performer, open it in same way you would a
DP project. To export a project to AudioDesk, use
DP's Save As command and choose the AudioDesk
2.0 file format.
