Choosing a DAE or Direct TDM Device
Selecting and activating a particular audio hardware device is done in the Logic Pro >
Preferences > Audio > Devices pane. You can choose between the Core Audio, DAE, and
Direct TDM tabs.
• Core Audio: The Core Audio tab is used to activate and adjust audio hardware devices
that use Core Audio drivers. Full details on Core Audio device settings are found in the
Logic Pro 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.
• Direct TDM: The Direct TDM audio engine of Logic Pro is used to process the
DTDM Mixer—which you can route into the (aux channel strip) inputs of the TDM Mixer.
This allows use of your computer’s CPUs to process Logic Studio and Audio Units
instruments and effects, while also using the DAE.
