I love the idea of these to create a background pad/drone. But could also see these being used to generate some melody ideas if you set it up with your desired notes and "skip time" until the generation is playing different notes out of "sequence", once things start to un-synchronise. An unexpected pattern could shine through.
I think some ability to "skip time" in the generation would be needed, as some of these don't get interesting until they've been running for like 30+ mins.
Maybe one for Robotic Bean?
