VCSK: PCB/panel set for vactrol resonant low-pass filter for Eurorack synthesisers (4HP)


PCB/panel set for the VCSK vactrol low-pass filter

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. 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
