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 default to 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 to check this. The MMC message format is a Sys Ex message, using a single byte to
define the message type. The table below lists the currently defined MMC messages:
