This is a small Buchla 200-inspired fixed rack. It contains everything you need to explore interesting sounds, but not big enough to lost your focus. It has 4 oscillators (258 and 259), two BP filters (291), 5-step sequencer from EASEL, 4 low-pass gates (292), 4 AD envelopes (281) and, of course, Source of Uncertainty (266).

As an example I build some creepy sounding patch, just because I can. But this rack can do much more. I did an ambient piece for it previously (can find it on my YT).
