Stray note-on event on transport stop

When I transport | stop, I’m getting a stray note-on event. (A note is playing.) I DO have a ‘MIDI Remote’ set up, but it uses nothing but program changes (in an apparently failed attempt to avoid just this issue). From where else might this stray note event be coming?

It’s easy to identify the offending instrument. When I change its channel, I still get the offending Transport | Stop note-on message. If I mute the instrument, no annoying note-on event – which only confirms that I have correctly identified the offending instrument (which I’d actually like to use!) AAARRRGGG! Please make it stop before I lose what little is left of my sanity! :slight_smile:
