I decided to share this as the principles and requirements are very similar to yours and the technology could be adapted with no real cost.

I made a recorder (sorry I don't know if you call it this in the US - it's a flute-like musical instrument) for an 8 year old girl who was born with only two digits on each hand. This instrument normally requires a full compliment of digits.

A manufacturer heard what I was trying to do and sent me 6 instruments to experiment with. I hollowed one on the lathe, made a PCB to fit inside it with 8 buttons along each side. The opposing pairs of buttons can be pressed with two fingers while the instrument is he;d with the other two. These button pairs are converted (by a Microchip PIC) into a MIDI stream and sent to a keyboard where they're converted to audio.

An interesting project for an excellent reason!
I am currently setting up an electronic wind controller with an mbed controller, capacitive touch sensors and a blow pressure sensor.
The pressure sensor has been the most difficult piece but now it is starting to work.
If you want more information about the hardware, please reply to this comment.
