I hadn't even noticed the zero velocity (not that it would've meant anything to me if I had).   Thank you!   - Bob IP Logged Jamie OConnell Administrator     Gender: Posts: 2027 Re: Status 90 for Note Off?? « Reply #3 on: Apr 27th, 2019, 7:39pm » Quote Modify It has always complicated MIDI command handling, because any computer code that handles Note ON and Note OFF, must be prepared to deal with both and/or either situation.     In practice, it has caused untold confusion and bugs in MIDI handling code.  I think it was a big mistake to allow it in the first place.
