any wisdom would be deeply appreciated.

Using Processing to "Paint Sound"

I'm brand new to Processing and am curious if anyone has suggestions on writing code for a kind of "color music" application. The crudest and most basic goal for me is to link 12 musical notes to the primary,secondary and complimentary colors of the 12 step RGB color wheel. Then to use a midi controller to allow the user to paint the color/sound.

Is it possible to use Processing, Minim and ProMidi to do this? For a beginner, is it a ridiculous goal? I've been hunting for tutorials and similar code, but have not been successful, if anyone has any suggestions, I would be tremendously grateful.

Thanks a lot.
