I use the oplab in my OP-Z to send and receive MIDI data and I just started having an issue with it yesterday. I’ll be playing a sequence and out of nowhere the MIDI will just stop sending/receiving. The sequence continues to play (I am often using the drum tracks on OP-Z while sequencing external synths), but usually some of my external synths have hanging notes because they didn’t receive a “note off” message when the Z stopped sending.
If I turn off and then back on the Z, it immediately works like normal again, but it won’t be long before it stops sending/receiving. Seems like it usually happens after 2-4 minutes of playing, but I’ve noticed that if I do an immediate restart, sometimes it will stop in less than 20 seconds on the next time.
I popped open the Z and the module itself seems to be seated properly so I don’t think that’s an issue.
Has anyone experienced anything like this? Any ideas about what else I might try?
