80 The MD8 & MIDI
Controlling the MD8 with MMC
Quite a few of the MD8’s functions can also be controlled using MIDI Machine Control (MMC) commands. MMC is short for a set of MIDI messages that can be used to control audio and video (tape) machines, disc recorders, and other equipment. Typically, MMC commands include Stop, Play, and Pause. As you will see, the MD8 understands a lot more MMC messages.
Here are the MMC messages the MD8 understands:
