hi all,
I'm trying to get a midi instrument to change its pitch (in real-time) according to the pixel brightness from a live webcam. does anyone know how it can be done?

i want to do similar things... not only brightness but movement
"video to midi" programs i found:

Tebo Software grabbo video to midi converter for beOS

and isadora for mac:

Can be done in GEM with [pix_data].
