Re: Midi Harp.

	Although I don"t have knowledge in this specific area I beleive  you
could
	detect a blow by an air pressure sensitve transducer. A draw would
cause a vacuum
	in the air chamber of the harp.  In a midi saxaphone air pressure only
need be detected
	notes are determined by contact switches on the ""keys""? - not sure
if thius is the
	correct terminology.  The air pressure in this case determines the
volume.

	Some questions:  Would you program in bends ie if the air pressure
hits a predetermined
	level would the note bend up or down ?  Would your aim be to make the
harmonica the
	same size and shape of a mechanical harp?
