Hello! I have a Yamaha P-125 digital piano, which can send MIDI/audio via USB host (square cable). So no 5-pin MIDI. I suspect I need a different converter than what I have, but wanted to check here. My goal is to use the P-125 as a MIDI controller for the OP-1. I have a USB A-B cable, then a A-C converter for the OP-1. The OP-1 doesn’t seem to sense any MIDI signal from the piano doing it this way. Do I need another cable? Thanks!
I have a very similar setup (Nektar MIDI controller with a USB B to A cable and then a USB A to C adapter plugged to the OP-1 field) and it does work.
Have you checked all the menus and settings to be sure you’re sending in the channel you want?
Also, have you tried this same setup but plugging it to a computer instead of the OP-1 field? This would help you debug if the issue is somewhere before getting to the OP-1 field.
