3.8.2 Assigning MMC Messages to a Button
MIDI Machine Control messages are used by some devices and software to control transport functions such as Stop, Play and
Record. The Transport controls on your Axiom keyboard can be setup to send MMC messages, however it is important to note,
that not all MIDI devices or software applications respond to MMC messages. Even those that do support MMC often need to be
set up manually to respond to these messages. Please consult the documentation relating to your device or software application
to check this. The MMC message format is a SysEx message, using a single byte to define the message type. The table below lists
the currently defined MMC messages:
Number MMC Command
01 STOP
02 PLAY
03 DEFERRED PLAY
04 FORWARD
05 REWIND
06 RECORD STROBE
07 RECORD EXIT
08 RECORD PAUSE
09 PAUSE
10 EJECT
11 CHASE
12 COMMAND ERROR RESET
13 MMC RESET
