I've had this happen when working with a songfile and doing taaks that require more than simply hitting PLAY and waiting for the songfile to go completely thru to the end. Almost always has to do with a songfile that has Strings or some other sustained MIDI Pad going on. Attempts to Stop a song at a bar where the Pad is sustaining through to the next bar leaves the MIDI output device playing the note with no chance to receive the next command that would normally stop the note if the file continued to play.

**While the MIDI standard does indeed include a "note off" command, the reality is that very few programs or sequencers bother to use the note-off command. Instead, they rely on Note-On plus Duration value to do the job. Use of Note-Off creates twice as much data and is considered superfluous. **

With BiaB, I have found that songs which contain PADS such as Strings, Synths, or other sustained notes can sometimes result in a stuck MIDI note.

In some instances, as in some of the pgmusic Demo songs, the stuck pad note happens because the songfile creator used either long duration times or the Sustain pedal CC to invoke the long or held Pad note and if I hit Stop before the computer receives either the Sustain Off CC or before the set Duration time of the note has been exceeded, the MIDI output device is left with the last command it received, ie Note On, but the Transport was stopped before one of those two necessary events could happen.

F12 ia the keyboard shortcut for the MIDI CC123 or Panic Button...
