Audio Hardware and Drivers
To use Logic Pro 8 with your TDM System, you will need at least Pro Tools HD 7.4 (on
both Intel and PPC computers).
Selecting and Configuring a Device
Selecting, and activating, a particular audio hardware device is achieved directly in
Logic Pro, via the Logic Pro > Preferences > Audio > Devices dialog. You can choose
between the Core Audio, DAE, and Direct TDM tabs in the Devices pane.
 Core Audio: The Core Audio tab activates and adjusts audio hardware devices that
use Core Audio drivers. For full details on the Core Audio device settings, see the
Logic Pro 8 User Manual .
 DAE: DAE is the abbreviated form of Digidesign Audio Engine. This is the driver
software used to access TDM hardware (including use of on-board DSP chips) in
Logic Pro 8.
 Direct TDM: The native Direct TDM (DTDM) audio engine of Logic Pro is used to
process the DTDM Mixer—which you can route into the (aux channel) inputs of the
TDM Mixer, using the ESB TDM. This allows your computer’s CPU to perform native
(instrument and effect) processing in Logic Pro, while using the DAE.
DAE Settings
The DAE parameters can only be set after activating the DAE. To do so, check the
Enabled box in the upper left corner of the DAE tab. You will then have access to the
following parameters:
