CoreMIDI

CoreMIDI refers to the built in MIDI support available in Mac OS X. It allows for you to set up what devices are attached to any interfaces with Mac OS X drivers. You can assign device names and attributes such as which channels they can work with, and what other features they may support such as MIDI Clock and/or Machine control. CoreMIDI is basically a built in system that gives you the power and flexibility in your MIDI system as OMS and/or FreeMIDI does under OS 9. Another advantage is that currently any CoreMIDI enabled application under OS X can utilize MIDI Time Stamping (MTS) with any of the MOTU MIDI interfaces.
