YouTube via carpeteria "here's a handmade, from scratch circuit with four oscillators that can run simultaneously, with a ton of noise and feedback possibilities. it's taped upside down, as the cord was in the way, but it sounds the same regardless. enjoy!"
YouTube via pac209 "quick jam with DSI Evolver, small but very versatile synth, the Evolver was getting additional notes via MIDI from a Mobius step sequencer"
via Synth.nl where you will find more shots and info.
Regarding this image: "There were also some very nice modular systems. In the picture you see a very nice Doepfer set. I did see that stuff on the Musik Messe, but never really played with it. Unfortunately time was to short now as well. There was so much to see. And by the time I wanted to give it a go the guy that brought it had left. On the right you see another modular system that was completely self designed. So a very cool DIY project. The SH-101 was used as a CV/gate keyboard."
