Check your MIDI cable and connection

If you think you are having issues with the MIDI OUT port on your controller, please first check that you have tried a different MIDI Cable to rule out the possibility of a faulty MIDI cable.

Also, please check that you have the MIDI Cable inserted correctly to the MIDI OUT port. The MIDI OUT port on the MC6 and MC8 have 7 pins, while regular MIDI cable has 5 pins. Hence, it is possible that you might have angled the MIDI cable wrongly when connecting to the MIDI OUT port.

Correct orientation on the MC6. MIDI plug is in line with the MIDI Port.

WRONG orientation on the MC6. MIDI plug is angled so all the pins are offset.

Testing the MIDI OUT port

• Connect the MIDI OUT port back to the MIDI IN port, so the Controller will send a MIDI message back to itself. It does not need to be connected directly. You can route the MIDI signal from the last device in your MIDI signal chain back to the MC.
• Set the MIDI Channel on the MCx to MIDI Channel 1
• Turn off MIDI Thru.
• Program a CC#127 value 127 message on Channel 1.
• When the controller receives a CC#127 message on it's MIDI channel, the display will indicate that a MIDI message is received.
