The music at any given point sounds great, like classic video game bgm, but theres one thing that irks me. I don't feel a clear start and end to the music, it just seems abrupt both ways.

true that, I'll try to improve the general structure, so that it sounds complete

it sounds like i expected it would :)

bad, or artificial? If "artificial" - that's the performance side, and it depends on the soundbank. If a real performer plays the same score, it would sound better. The point is to have nice compositions first :)

sounds are ok (to my untrained ear), and great effort building this!

still, a little too random

since it's algoritmic, maybe you can go for a little "coherence" throughout a piece, if it makes sense?

I deliberately made it generate/play tracks with 0 user input. This thing might be good, but I couldn't make it play anything meaningful

I have generated quite a bit of music using evolutionary algorithms. My research is mostly about figuring out representations that are not at too low a level (eg 1 "gene" per note). I like representations that in some way represent the patterns, oscillations, and processes that seem to drive music forward over time.

A paper: http://ncra.ucd.ie/papers/gecco2011_jmcdermott.pdf

Longer, slow-developing stuff on soundcloud (using slightly different software): http://soundcloud.com/jmmcd/tomorrow-is-a-new-day

they sound pretty nice :) will read the paper immediately

Nice work. Is anybody aware of automatic music performing software? I think that this is similar to automatic generation of music but more structured and therefore easier to implement. I remember reading some studies about software performing classical compositions, but never found working prototype to play with.

I've read some papers about software used to help live performers, some sort of co-performer, or accompanying robot. But I can't find the paper right now..

Hmm, no mention of Prof. Cope at UCSC http://artsites.ucsc.edu/faculty/cope/experiments.htm

My thoughts exactly. Virtual Music gives a great insight into Cope's ideas: http://mitpress.mit.edu/books/virtual-music

Sadly his code (lisp if I remember correctly) isn't on github either...

Thanks -- I think they're kind of nice at a "local" level, but they don't have the more "global" coherent movement that yours have.
