Steiner-Parker Diode VCF

The design is based on the Steiner-Parker diode filter, and I stripped it down to a minimal set of components while keeping its characteristic sound. It has controls for frequency cut-off, resonance and CV level. There are distinct inputs for low-pass, band-pass and high-pass.
There are PCBs/panels and full DIY kits available.
