MIDI
Pro Tools | Duet’s USB MIDI I/O provides a MIDI connection between class-compliant Core MIDI devices (i.e., keyboards and
other controllers) and Mac OS X.
A class-compliant MIDI device works with Core MIDI without needing to install drivers or additional software. To confirm that
your MIDI device is class-compliant:
1 Connect the device directly to a Mac with a standard USB cable.
2 On the Mac, open Audio MIDI Setup from Applications > Utilities.
3 In Audio MIDI Setup, choose Window > Show MIDI Window.
4 Verify that the MIDI device is detected in the MIDI window.
If the device is detected, it is class-compliant available to MIDI software.
5 If the device is not detected, click Rescan MIDI.
