Reface#1 midi out to Reface#2 midi in
Sure, I am smart enough to understand that without asking. But this requires 2 Reface-MIDI breakout cables + one (or two if I want to connect in both directions) normal MIDI cables. I am sure it works, but it sounds like asking for problems. I was hoping a special USB or MIDI cable would exist to allow a connection with only one single solid cable.
P.S: The mini-midi-connectors-with-adaptor-cable were not a great design choice in my opinion. Very much non-standard. I hope Yamaha will have enough spare cables in stock when we need replacement somewhere in the future.
