If you ever want to create a piece out of scratch, you may want to get a computer do it for you.
Just choose some fragments of music and put them in your computer and he will make the music for you. I guess it's a notation program where you can input the notes, you can input some ideas of yours and the music comes itself. (I don't know) I can't imagine he would take mp3 samples, so you really need to write the score or some parts of it. I think it uses algorithms like no dissonants placed together or a tonal/kwint chord after every 4 measures.

I listened to the Beethoven moonlight sonata (see: sonata movement (after Beethoven) on the mp3 page) and it sounds interesting you know. Chopin was wonderful too. These are played live I think, because I can hear the pedal. But the composition is made by a computer.
PS: this would certainly be a good instrument for the "Classical Remix" - noctaventure...
