I have a Roland J-6 and a Roland MC-707. I'd like to use the J-6 as a midi input device on the MC-707. I've tried the following:
- J-6 USB-C to MC-707 USB. Didn't expect this to work and it proved to be the case.
- J-6 MIDI OUT to MC-707 MIDI IN via a converter cable (https://www.amazon.co.uk/gp/product/B07P5RJJ6W). This was advised by the folks where I bought the MC-707. This doesn't seem to work.
- J-6 USB-C to Macbook and MC-707 USB to Macbook with J-6 OUT configured as MC-707 IN via MIDI Studio. This didn't work, thankfully.
