Final Project Direction

I am continuing research on sound and music in processing. I am still interested in storing data in a visual format. Even if my project ends up only storing a few notes on a sheet of paper, I will be happy. Right now there are a few big issues that I still need to adress. 1. Simplify Midi music tones or an even simpler format to as few notes as possible. Give each note a unique shape and color/texture value. Format processing to output this data into a visual piece. 2. A way to read back the visual data back into processing to create the midi file again. I envision that a scanner would work well for the purposes I need. 3. Processing has to be able to read back the data on the page. It would have to follow a certain timeline and find colors and analyze them to pull out the notes. It could re-create a midi file and play it. Eventually I would like to have a handheld scanner that could create music from any surface. What would a gallery wall sound like if you could hear music in it. I still need to research more. Maybe I should just jump to the ability to read sound in textures instead of creating my own system for encoding.
