I’m trying to use a Yamaha DX7 as a midi keyboard, but I’m having issues with occasional stuck notes (about every 10th keystroke on average)
The keyboard does not have stuck notes when I use it’s own synthesis, so it can’t be a mechanical
issue with the keys.
Looking at the midi log in synthian’s web UI, I see that the event that should be a note-off (a note with velocity zero is MIDIan for note off) the same velocity as the note-on event is repeated. I also hear the note re-triggering when I release, consistent with the event.
I’ve tried to Google to see if this can be a bug in DX7s midi implementation, but it doesn’t appear like others are having the same issue. Seeing that some other people have had stuck notes on their Zynthian with certain controllers, it seems somewhat more likely that the issue lies there.
Any idea what I could try?
