Eurorack Diode VCF Kit/PCB Modular Synthesizer

This filter is part of my Eurorack series. 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, which allow all sorts of filter responses when combining them.

Key features

• voltage controlled diode filter
• inputs for low-pass, band-pass and high-pass response
• controls for frequency, resonance and CV input level
• two CV inputs for controlling the cut-off frequency
• easy to build, all through hole components
• 10 HP

The kit includes

• all needed quality components
• optionally matched transistors
