Speaking of which; I hacked a rudimentary "digital theremin" the
other day. :-)
I use a Wacom Intuos A6 USB tablet with a Stylus pen (cordless, with
rocker button on the side and an eraser tool in the other end) to
control amplitude, pitch and 3 overtones; 4 sine oscillators total.
(The thing is pressure and tilt sensitive, that is.)
The accuracy is incredible (of course - it's a professional tool for
freehand drawing), and the data rate is approximately 420
events/second, weighted so that there are about 100 X/Y coords per
second. This seems to be quite enough, even without filtering.
Works a lot better than I expected. :-)
Oh, there are various other tools for the tablet, such as the
Airbrush, which has a wheel in addition to the features of the
Stylus. Wonder what one could play with that...
