VCSK: Pre-built voltage-controlled low-pass resonant Sallen-Key filter for Eurorack (4HP)


A VCF finally hits the line-up

This is a pre-built version of the voltage-controlled Sallen-Key filter PCB/panel set 

Filters don't need to be massively complex to sound good, and it's amazing the sort of noises you can get out of an op-amp and a bunch of passive components. There's an input and output, of course, plus a CV input with an attached attenuator which feeds into a pair of vactrols, which is where the magic happens. With a bit of care, you can get everything from nice filter sweeps all the way up to squonky acid-bass and beyond. These modules have been built up using the component values that I recommend in the BOM for the PCB/panel set. Don't expect super-snappy responses either, because vactrols are doing a lot of the spadework.

In common with all my other modules, this is supplied with a panel made from laser-cut and engraved 3mm black perspex - mounting hardware and a power cable are also supplied
