Lowpass mode, first without resonance and then with. 

Bandpass mode, first without resonance and then with. 

Highpass mode, first without resonance and then with. 

Triangle output from Z3000 added to HP input. (Pulse output, with increased PWM, is in the LP input.)

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. .
