in the Performance monitor when making this
adjustment. Be sure to try playing some audio, too,
as the processor meter can jump up significantly
during playback at lower settings. Also, use
CueMix Console; it’s message center feature helps
you find the optimum Samples Per Buffer setting
for your system.
For further information about CueMix console
and reducing latency, see chapter 12, “Reducing
Monitoring Latency” (page 105).
Figure 8-2: When adjusting the ‘Samples Per Buffer’ to reduce patch
thru latency, watch the ‘processor’ meter in the Performance Monitor.
From the Basics menu, choose ‘MOTU Audio System options>Perfor-
mance Monitor’. If you hear distortion, or if the Performance meter is
peaking, open CueMix Console and look at its message center for
hints as to what’s going on.
Monitor Outputs
This setting determines where you’ll hear things
like soundbite auditioning, audio scrubbing, and
real-time previewing of Adobe Premiere audio
plug-ins.
ENABLING INPUTS AND OUTPUTS
The middle portion of the PCI Audio Console
window determines which inputs and outputs
you’ll seen in all of AudioDesk’s audio input and
output menus. To make an input or output
available in AudioDesk, check its box. For further
information about making these settings, see
“Interface settings” on page 70.
BE SURE YOU HAVE ENOUGH VOICES
Once you’ve enabled the desired PCI-424 audio
inputs and outputs, go to the Basics menu and
choose MOTU Audio System Options>Configure
Studio Size. Then check to make sure you have
enough mono and stereo audio voices for the work
you need to do. Consult the MOTU Audio System
chapter in your AudioDesk manual for further
information about the settings in this dialog.
24-BIT OPERATION
Your PCI-424 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 Basics menu, choose MOTU Audio System
options>Configure Sample Format, and choose
24-bit recording as the sample format. This setting
is saved with the AudioDesk project.
INPUT MONITORING MODE
To determine how AudioDesk will monitor input
from the PCI-424 system, go to the Basics menu
and choose MOTU Audio System options>Input
Monitoring Mode. For complete details, see your
AudioDesk manual.
SYNCHRONIZATION
AudioDesk can run under its own transport
control or slave to an external sync source, such as
SMPTE time code or ADAT sync (sample address).
Running AudioDesk under its own transport
control
If you do not need to synchronize AudioDesk with
time code or another recording device, such as a
tape deck, just leave the Slave to External Sync
command in the Basics menu unchecked.
However, even though AudioDesk is not slaving to
external sync, you still need to be concerned with
the synchronization of the PCI-424 system’s digital
audio clock with other devices connected to it
digitally (if any). For example, if you have a digital
mixer connected to a 2408mk3 interface via an
ADAT optical lightpipe cable, you need to make
sure that their audio clocks are phase-locked. For
details, see “Syncing ADAT ‘lightpipe’ devices” on
page 46 and “Make sync connections” on page 35.
