Assigning MMC Control to Buttons
The transport functions of some hardware recording devices and DAW applications can be remotely operated via
MMC (MIDI Machine Control) commands. MMC is a specialized transport control protocol and requires a somewhat
different configuration method. The following values need to be specified:
Key
Control Assign
Channel Assign (example)
Data 2 (example)
The following example will configure a button to send the MMC command "Play". Select an assignable button as
described earlier in this guide.
1. Press the Edit button.
2. Press the Select button or Control Select (Ctrl Sel) key.
3. Select a button as described earlier in this guide.
4. Press the Control Assign (Ctrl Asgn) key.
5. Type 149 using the number keys. This sets the button to
send MMC (MIDI Machine Control).
6. Press the Channel Assign (Chan Asgn) key.
7. Enter 127 (Poly On) using the number keys. This ensures
all receiving devices will respond to the MMC messages.
8. Press the Data 2 key.
9. Enter a number from the chart on the side to select the
MMC command for the button. This determines which
transport function will be controlled by this button. For
example, enter 2 for the Play command.
10. Press the Enter key.
