MS20 VCF module

This Eurorack module is based on this schematic: http://electro-music.com/wiki/pmwiki.php?n=Schematics.KorgLateMS20Filter

After breadboarding the circuit I decided to create a eurorack module out of it. There are a few component value changes compared to the original but most of it is identical.

The filter has a very wide frequency range and can be used as a lowpass gate. The filter can also be used to create synth drum type sounds if used with an envelope generator connected to a CV input and the peak/resonance control turned up until it oscillates (no input signal required).

This is also the first time I used a circuit board for the panel (manufactured at PCBWay.com). I’m very pleased with the result. :)
