Serge Modular's Stereo VCFQ — The Classic Variable Q Filter, Now in Stereo!
The Serge VCFQ has been a staple of modular synthesis since Serge Tcherepnin designed it in 1976 as part of his third generation of modules. This stereo version, made in collaboration with Random*Source, pairs two of those iconic 2-pole (12dB) variable state filters behind a shared set of controls — Frequency, Q, and their respective CV inputs — for true stereo processing. Each channel provides simultaneous low-pass, band-pass, and high-pass outputs, giving you six filter taps from a single module.
The inputs are attenuated per side, which is useful for managing levels and for driving the filter into percussive overload territory. An unattenuated AUX IN feeds both channels at once; this input can be handy for injecting a mono signal into the stereo field. Send a pulse into the TRIG IN with the resonance cranked, and the filter rings like a struck object, producing everything from woody clicks to bell-like tones, synthesized water drops, etc… If you patch a high-pass output back into the input and push Q further still, the filter will self-oscillate into a nice sine wave, which is trackable via the 1V/Oct input and lets you play it chromatically at that point.
Nearly five decades on, the VCFQ remains an incredibly appealing and musical filter. If you know the VCFQ, you know what this is — having it in stereo feels like a long-overdue gift!
