The idea is to use the x-y coordinates as two independent parameters to
a synthesiser, so the sound would vary smoothly between one point and
another. A simple example would be to put a snare sound through a
resonant low pass filter. The x coord would be the filter cutoff, and
the y coord would be the resonance at the cutoff frequency.
There are many other possibilities. I'm planning to use supercollider to
make the actual sounds.

In this case, I use Midishare, that for me is fantastic. There is already one year that I read the posts in this mailing list, and nobody speaks about midishare... I miss something? I there a better way to do that?

I think I'll have to go for 2 - the algorithm for mapping the sensor
readings into coordinates looks like being too complex to run on a small
board like the arduino.
