Configuring the Digidesign
CoreAudio Driver
You can configure the Digidesign CoreAudio
Driver using Digidesign CoreAudio Manager, or
from within most third-party CoreAudio-com-
patible client applications (such as BIAS Peak or
Logic Audio). Consult the manufacturer’s docu-
mentation for more information.
Some applications (such as Apple’s iTunes or
QuickTime Player), also require that you config-
ure either the Apple Sound Preferences or Apple
Audio MIDI Setup to use the Digidesign Core-
Audio Driver.
Digidesign CoreAudio Manager
Use Digidesign CoreAudio Manager to change
the CoreAudio Buffer Size setting, access the
Hardware Setup dialog for your Digidesign hard-
ware and control volume and mute for the Core-
Audio driver. Digidesign CoreAudio Manager
also identifies your Digidesign hardware, the
supported number of Input and Output Chan-
nels and the number of attached clients (appli-
cations).
Digidesign CoreAudio Manager cannot be ac-
cessed under the following circumstances:
• When Pro Tools is running
• When another application is using Direct
IO (such as the Ableton Live Digi Edition)
The Digidesign CoreAudio Manager application
launches automatically when the first client ap-
plication accesses the CoreAudio driver. You can
prevent an application from accessing the Core-
Audio driver by holding down the Shift key just
before the application would access the Core-
Audio driver, typically during launch of the ap-
plication. Certain applications (such as Apple
Mail and iChat), do not access the CoreAudio
application until they first play a sound, so you
will need to hold down the Shift key just prior to
sound playback in order to “opt-out” of using
Digidesign hardware for playback.
