I spent this evening after band practice experimenting with some sounds in Propellerhead’s Record 1.5 and Reason 5.0.
This resulted in a track called tenseToExciting (descriptive, eh?). It’s on my music page here.
I might at some point do a proper look into how I made the sounds. They didn’t actually take that long, and I was pleased with the unpredictability of some of them. It might be fixed media (ah-ha! my arch nemesis!) but you can still utilise some pseudo-random effects.
