@tubetime but that does it do when you push it?
miunau@RebelbotJen @tubetime it sends a stop note midi message on all channels (and maybe all notes on all channels, can't remember). midi is so flaky if you go too fast some synths just can't process the messages in time so notes can hang on forever.
Petr Tesarik@miunau @RebelbotJen @tubetime It should send MIDI All Sound Off (CC 120), not All Notes Off (CC 123), because the latter will maintain note release time, and notes held by sustain will not turn off until the sustain pedal is depressed.
