The GCX responds to MIDI Control Change messages 80-87 on MIDI channel 16. A data value of 127 turns a loop on and 0 turns a loop off.

On the Mastermind you will set Continuous Controller Destination 1-8 to send CC#s 80-87 respectively, on MIDI channel 16 in Global Setup. Then you will assign the data value for each Continuous Controller 1-8 within your presets for the correct loop state in Preset Setup.
