I wrote a harmonica simulation program that plays and teaches a few songs
and allows the user to play the on screen harmonica by using the top row
number keys along with the shift key. I use the keyDown event to determine
when to start a note. I would use the keyUp event to determine when to stop
a note.

The first version of "Harmonica Helper" is available for downloading at
