I discovered this too, the same way, while writing MIDI filters.  I then read, I
think here, that most MIDI controllers do this note-on with zero vel thing instead
of note-off.  My first cut of the code was written for note-offs, but the first
filter I wrote wouldn't work correctly.  The amended code works fine.
