Click the Preferences button in the Arrange toolbar, choose Audio from the pop-up menu,
then click the Devices tab.
The Devices pane contains three further tabs: Core Audio, DAE, and Direct TDM.
In Mac OS X, all audio devices (with the exception of DAE and Direct TDM devices)are
accessed via Core Audio, an integral part of the operating system. Core Audio is a
high-performance, low-latency audio system that allows audio interface hardware to be
used by several applications at the same time.
Logic Pro is compatible with all audio hardware that offers a Core Audio driver.
Logic Pro also supports DAE (Digidesign Audio Engine) and Direct TDM. These drivers are
used for the operation of Digidesign HD system hardware, and allow Logic Pro to access
the on-board DSP chips of these devices.
