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).
Operating MMC-compatible
devices with the BR-900CD
This section explains how to make settings for synchronizing
the playback with a computer-based sequencer program that
supports MMC and MTC. Make connections as shown in the
