From the project
CEM3350/AS3350 based 8 channel VCF
This repository contains schematics and Kicad PCB layout for an eight channel voltage controlled filter (VCF) based on the CEM3350/AS3350 state variable filter. Both frequency cutoff and resonance (Q) are voltage controllable. It offers a simoultaneous low-pass and band-pass output.
