iOS - MIDI NoteOff does not work #230

idekterev commented 6 years ago

I'm using MIDI.JS to manually play some notes (one note at a time, nothing complicated). When running under Android, everything works fine. Under iOS the sounds get 'stuck', like someone leaving the sustain pedal on. I've traced the problem to noteOff commands, which do not seem to function correctly.

Running iOS 12.2.6 MIDI.JS v0.4.2 running in Cordova, SoundFont files loaded locally.

As an example, the following code works correctly in Android: MIDI.noteOn(0, 50, 127, 0); MIDI.noteOff(0, 50, 0.01);

Under iOS, the sound keeps playing and does not cut-off (the noteOff command has no effect).

I believe that this has been fixed in the https://github.com/mscuthbert/midicube fork.
