VCF74 Rev-A

VCF clone of 1970s Mini-Korg (Rev-A prototype)

The VCF74 is an enhanced version of the 1970s Mini-Korg 700/700s filter circuit, a.k.a. "traveller". It has independent high-pass and low-pass filters with CV inputs. CVs for the filters can be controlled via a variable gain/attenuation stage. The input and output audio paths also have independent gain controls. Additionally, there is a variable resonance and brightness control. Note that Rev-A (prototype only) does not have a CV for resonance, although plans for a CV controlled resonance are going to be implemented in the Rev-B model.
