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 |
