Novel(?) Auto-Arrangement Method

[to_the_sun]

I haven't looked extensively into the kinds of "auto-arrangement" software that are out there but as far as I have looked, I've never found anything that could suit my own personal goals. So I began developing my own project. I feel like my Amanuensis, as I call it, is novel because rather than "coming up" with notes or a beat that fit what you're playing, it does nothing but analyze, cutting out bad parts and reasserting the good stuff you play. Through an algorithm of pattern detection it is able to understand when you are playing a steady rhythm, adjust the volume to cut out out-of-tempo portions, identify repeated riffs/beats, precisely pull out single iterations of such patterns and begin looping them in separate tracks (with whatever instrument you want to give it, say drums if you're on keys, or vice versa), all in real-time. Basically it is an AI that you can jam with. Further development will lead to fully arranged songs constructed spontaneously during a jam session, as multiple AIs playing different instruments scan for patterns and communicate with each other as to when they should each come in and/or cut out. Your job as a user will be to simply play your instrument of choice, however you wish, repeating riffs which will give the program fodder to work with and, once a sufficient structure has been built up to back you, laying down flourishes and solos on top of it. Can anyone confirm or deny the novelty of my idea?

Here is a pic that shows the Amanuensis in action:

Max for Live is my medium of choice, and I will extol its possibilities and the ease of creating things with it until the day I die. The track labeled NPC 2 is me, playing the keyboard. The track below it is fully autonomous; you can see where it picks up on patterns I began repeating.

Here's a test recording:

The drums are the Amanuensis, the keys are me. At the beginning of this recording the Amanuensis is playing a simple beat which it had picked up earlier. About 30 seconds in you can hear it switch to the new pattern. My soundcloud has a lot of other recordings I've made with this program (and will continue to be flooded with new ones.)
