Following on from the "closer look" video, here's a full performance with the Roland System 100m from 1979. I tried to demonstrate the versatility of a setup like this by making things like full drum kits, squelchy basses, phased and delayed textures with sequenced filter mod, synth guitars, ring mod nastiness, audio rate down-sampled formants, voltage processed LFOs, lush Jupiter-esque polyphony, a singing and gliding lead, sounds that can't really be described and more. Many sounds were also created in groups together at one time because you can! The eagle eyed among you may have noticed that there were actually five 191-J cabs used in the video, although only four at one time.
