MIDI notes with a velocity of zero are the same as MIDI note off.
(This is to enable running status, which saves a bit of bandwidth on
the old, slow, MIDI cable. Only the first event status message needs
to be sent for the first note-on in a bunch, then after that all data
bytes received until the next status byte is received can be assumed
to all be notes, with zero velocity meaning the same thing as
note-off, but not requiring a new event status to be sent.)
