Steps to reproduce the behavior:

1) Start with a stave with notes already input
2) "Play notes when editing" should be set to "ON"
2) Midi output should be sending midi to any external synth engine of your choice (software or hardware will both have the same result)
3) Start playback
4) Before the piece of music reaches the end (or a whole bar of rest) stop play back using the transport controls

Resulting behavior:
Any connected synth will continue to hold which ever note was last played, since Musescore does note send note-off messages when play back is stopped

Expected behavior:
A midi note-off message should be send for any sustaining note so ensure that any connected synth does not continue to hold a note unintentionally
