Actually, one of the initial motivations for creating Overtone was to experiment with automating "feel". I was getting into electronic music, and it seemed to me that many of the painful aspects of EQing and adjusting instruments and timing so they don't interfere with each other could be automated. We haven't really gotten to this point yet, but I tend to believe that this is yet another area in life where people will argue forever that software will never compete with humans, up until the point where many of the top tracks are being generated by software. It also opens the door to all kinds of interesting things, like live composition of multiple instruments, or meta-composing, where you modify parameters along axis like tension, emotion, drive, and vibe, rather than figuring out how to modulate to the next key. For now I agree with you though, most of what I create in Overtone still has a robotic feel. Hopefully that won't be the case for long. We'd love to have more musicians joining the discussion though, so if you have ideas join the mailing list.
