The MR5 is setup to respond to both MIDI Control Changes and Program changes. Control changes can select both guitars and individual amplifiers on the JX44. Program changes are reserved for amplifier selection only, which allows for custom configurations with multiple amplifiers on devices like the JX44. The following chart shows which instruments and amplifiers will be activated when the MR5 sees various Control and Program changes sent by your MIDI pedal board or sequencer:
