I never got past the demo. I found control of timing to be less flexible than I wanted, and while "wormhole" connections are supposed to be instantaneous (durationless), in reality they "flam," which makes it problematic to create structures with chords.
Thanks for the responses. I've always been interested in generative music, but what little software existed seemed either too abstruse or expensive for what may have ended up as a toy. At 30USD, Nodal seems cheap enough to take a chance on. As I said, so far the results are intriguing - one thing I haven't tried yet is hooking the midi signal up to a micro-tuned instrument...hmmm(strokes chin)
