Ask HN: Audio software idea for extreme geeks

Hi,I had an idea I felt like posting. There is a software program called Melodyne that has developed technology that can take polyphonic audio recordings of instruments (such as a recording of a piano chord) and literally split it into its component notes. I was thinking it would be really cool if somebody developed a synth/audio editor that would do the same but would split the file in a manner based on user definable parameters. The split derivative files could then be put into lanes for individual processing.Then the file could be re-collapsed into a single file. Even though it's a derivative idea, it seems like it would make a great sound sculpting tool. If anyone reading this knows anything that exist like this on the market please post it :)
