Chapter 16—MIDI
MIDI & the D24
The D24 supports the following MIDI messages:
• MMC (MIDI Machine Control) for remote control with, for example, a MIDI
sequencer—See "Using MMC (MIDI Machine Control)" on page 178.
• MTC (MIDI Timecode) for synchronization with MTC-compatible equipment—See
"Timecode & the D24" on page 134.
MIDI Ports
The MIDI ports are used to connect the D24 to other MIDI equipment for use with
MTC and MMC.
The MIDI IN port receives MIDI messages, the MIDI OUT port transmits them, and
the MIDI THRU port retransmits all MIDI messages received by the MIDI IN port.
Using MMC (MIDI Machine Control)
MMC allows you to control the D24 remotely using a MIDI sequencer or other device
that can transmit MMC commands, so when, for example, you start playback on your
MIDI sequencer, the D24 starts playing as well. Since the D24 does not support MMC
when it's configured as an MTC or SMPTE/EBU timecode slave, it must be the time-
code master (see "Timecode & the D24" on page 134). Among the D24 functions that
can be controlled via MMC are Stop, Play, Fast Forward, Rewind, and Record. See the
table page 179 for a list of supported commands. The D24 does not transmit MMC
commands.
