Im working on a similar project only my color is out put to video. I'm also new to max and have been out of college for almost two years. I got about as far as you, i'm controlling color with my audio level, but I want to use music notes to trigger exact color according to Newton's theories. If [analyzer~] can give me a music note that would be amazing but i think what really needs to happen is we need to get wave length and frequency displayed in a [flonum] box. wiki optics for info on color sound harmonization.
