DIGITAL PERFORMER

1 Record-enable a track in Digital Performer.

2 Choose the desired 8pre mic input for the track.

3 Open the Audio Monitor or Meter Bridge

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 31, 8pre audio inputs and outputs will appear

in Digital Performer’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

Digital Performer’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 28.

Mix1 1-2

In Digital Performer’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 Digital Performer (for reference and

archiving purposes). Further, if you are sending

audio from Digital Performer 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 Digital Performer. 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 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, 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 Digital Performer 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 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 45).

SYNCING TO SMPTE TIME CODE

Digital Performer 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 AUDIODESK

Digital Performer can exchange projects with

AudioDesk. To open an AudioDesk project in

Digital Performer, open it in same way you would a
