As its name suggests, the Erica Synths Black DJ VCF provides sound processing functionality typically found on DJ decks – it is fully open when the cutoff knob is set to 12:00. When turned counterclockwise, lowpass filtering is applied, and when turned clockwise, highpass filtering is applied. The filter also has a pleasant-sounding resonance parameter. This module offers hands-on control over the sound during performance, as well as unconventional timbre modulations that are difficult to achieve with conventional state variable filters. The Black DJ VCF is a fully analog design and consists of two VCFs – highpass and lowpass in series, with filter management done through complex CV routing.
