[sdiy] Make a CS80

[Tom Wiltshire]

I've been wondering about Quantum Tunnelling Compound for polyphonic  
aftertouch.

You'd mount a small pill of QTC under each key, sat on top of a PCB  
with 'fingers' etched on it. A microcontroller could then read the  
resistances of all the pills and report back to the voices. It's  
fairly strightforward, but I haven't tried it yet.
