Apple Logic Express 9 - Manual (Page 44)

Setting Up Core Audio Devices
Logic Express automatically recognizes any installed Core Audio hardware, and uses the
default settings as defined in the Audio MIDI Setup utility (Applications/Utilities/Audio
MIDI Setup). It can, however, be advantageous to optimize the settings for your individual
hardware setup, particularly if you use several audio interfaces or a multiple input/output
device. If possible, you should avoid using different audio devices for input and output.
For details about setting up your Core Audio device preferences (in the Logic Express >
Preferences > Audio > Core Audio pane), see
Core Audio Device Preferences .
