Thanks! I'm aware of super collider and it is cool. However i'm not interested in real-time. I have been generating midi patterns and rendering audio server-side over many hours. I've started hand rolling a system to play drum samples from generated patterns. It would be nice if i could find something already built.

Maybe a music-oriented programming language like Chuck, Supercollider, or Pd?

I would recommend looking at Pd (Pure Data), which, imho, is the open source version of Max/MSP, a very popular graphical programming language used for music composition as well as the creation of audio applications.
