Very interesting.
I'm also interested in this area, nothing to show at the moment. I'm working with
arduino,
great possibilities!!
I don't understant if you want to map different areas from your surface to different
instruments (cymbals, tom,...) or something different...
In theory, if you have the strength of each signal independent, it is possible to
calculate
the (x,y) position, no?
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.
With arduino you have two posssibilities:
1) to build a midi controller itself: the arduino sends the midi messages and you need
just a synthesizer to produce sound. It's a firmware solution.
2) the software solution. You detect the signal in the usb port, and you need to program
a little (or big) application to convert you signals to midi notes (or anything else that
produces sound). 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.
