Peter Dyer has posted a YouTube video demonstrating a selection of presets he contributed to the factory patches for the DSI Oberheim OB-6. He had this to say, "No midi or post processing, these sounds are purely from the OB6 and played live or via the built-in sequencer. I enjoy taking part in the process thoroughly. Enjoy these warbly tones, squirmy PWMs and wet SEM filters."
