Audio devices overview
Logic Pro works with Core Audio–compliant audio devices, including Thunderbolt, FireWire, USB, ExpressCard, and PCI audio interfaces. You can connect microphones, electric musical instruments, and other musical equipment to your computer, or to an audio interface or other audio device. Logic Pro supports input from digital audio interfaces up to a maximum sample rate of 192 kHz, and a maximum bit depth of 24 bits.
If you use an audio interface to connect instruments or other audio devices, check the manufacturer’s specifications to make sure the interface is compatible with the Mac OS X version required by Logic Pro. Also make sure the audio interface uses a format supported by your computer. Follow the manufacturer’s instructions, which may include installing the correct driver on your computer. Check the documentation that came with the device, and the manufacturer’s website, for more information.
Logic Pro 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). However, you may want 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 Pro > Preferences > Audio > Core Audio pane), see Devices preferences.
