Synchronizing with MIDI Devices

Using MMC

MMC stands for “MIDI Machine Control.” This is a protocol that uses MIDI System Exclusive messages to remotely control multiple recording devices from one device. Your BR- 900CD supports the MMC protocol.

By using MMC, your BR-900CD can send commands such as PLAY, STOP, and FF to connected MIDI devices to operate them.

Some MIDI devices do not support the BR-900CD’s MMC functionality. If so, it will not be possible to operate them from the BR-900CD using the procedures described here. For details on the MMC functionality supported by the BR- 900CD, read “MIDI Implementation” (p. 216).
