Pardon me, but I only have two devices that output MIDI at this time – an OP-1, and a Roland GR-55 Guitar Synth.
The following code works great on my roland guitar synth: montage-organ/montage-organ.html at main · lindseymysse/montage-organ · GitHub
But it does not work on my OP-1. I am connecting to the device as usual, with OP-1 hooked up via USB in MIDI mode, but it doesn’t seem like my OP-1 is broadcasting any MIDI out.
Is there something on the hardware side I should know about?
