4 pole VCF from the classic ETI/Maplin synth in the 1970s

Classic VCF using unique switching-resistor technology that adds a slight CMOS distortion to the signal path, and dual Sallen-key filter blocks (think the MS20 or the Buchla LPG) for a bright, brassy sound. Very nicely controlled resonance as well!

We have added a stand-alone exponential converter so you have the option of the original's linear control characteristic (it will track your MS20's CV out!) or full integration with modern eurorack.

Buit with the approval and participation of the original designer Trevor Marshall.
