I am thinking about building an electronic instrument.  Actually, it will
be an input device for a computer music program that uses saxophone      
fingerings.  I know that Casio makes a little MIDI sax and that there are
several very high end machines, but I thought this could be a fun (and
inexpensive) project, especially if I let the computer do the sound 
generation and maybe even MIDI encoding.  The keys are going to be simple
switches that will be encoded via TTL or CMOS logic and send in throught
the parallel port of the computer (to leave the serial for MIDI (on an
Amiga if you're interested)).  

My problem is the mouthpiece.  What should I use?  What I need is some
kind of device that outputs a digital or analog signal proportional to
the pressure of an airstream applied to it.  The sensor should be cheap
and immune to moisture and should respond to changes quickly.  Does anyone
have any suggestions?
