This is a quick demo of the CGS35 Steiner Synthacon VCF, as built on the MSU panel by Clarke68 @ Muffwiggler's. It's running on 12v in a Eurorack system. There are sweeps with and without resonance in all 3 modes, then a little 'action' at the end where it gets wiggled a bit. 

The VCO used is a TipTop Z3000, it's the pulse wave output with a touch of PWM from an LFO. I didn't attenuate the signal going into the VCF, so it's a little overdriven (which sounds great in this case.) There are no other modules used, until I add some modulation and sequencing at the end. .
