SputnikQuad VCF/VCA Lowpass Gate + Mixer

Sputnik Quad VCF/VCA

The Sputnik Quad VCA/VCF is based on the Buchla 292 Quad Dynamics Manager and renowned as one of the best LPGs on the market. The module features four independent VCAs, each with audio and CV inputs. Each amplifier features a three-position switch for changing between VCF (low-pass filter) mode, combo (where the spectral response varies in accordance with changes in gain), and VCA. In terms of outputs, the module offers a mix out, odd channels out, and even channels out—meaning users can combine signals in interesting ways then route them to other portions of their synthesizer for a variety of sonic possibilities.
