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:
The following example will configure a button to send the MMC command "Play":
1. Select an assignable button as described earlier in this guide.
2. Press the Advanced button.
3. Press the Control Assign key.
4. Type 149 using the number keys. This sets the button to send MMC (MIDI Machine Control).
5. Press the Enter key.
6. Press the Advanced button.
7. Press the Channel Assign key.
8. Enter 127 (Poly On) using the number keys. This ensures all receiving devices will respond to the MMC
messages.
9. Press the Enter key.
10. Press the Advanced button.
11. Press the Data 2 key.
12. Enter a number from the chart below 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.
13. Press the Enter key.
