Theres a program that has tons of songs already processed and you can watch the notes an learn them :)
I know Audiosurf uses a similar technique by using the tempos and beats of music to shape the curves, bumps, and drops in the road.So I'm pretty sure there's software that does that.
There are programs that let you create sheet music, and I have seen experimental software to convert audio files into midi and then print it as sheet. Naturally, these should not be used seriously. They are unstable.
Can you provide links to them? At least I just want to try them out
