Multimode Filter

Root Locus is an analog 12dB/octave multimode filter, based on the CGS512 VCFQ filter. It adds a dual input crossfading mixer with gain control and a variable mode output with cv control for sweeps between filter modes, aiming for an extensive tonal variety! It also features a Ping input that allows for an impressively wide variety of percussive sounds. The Sub Range switch makes it a very versatile CV filter too, able to filter control voltages as well as transforming it to a VC Slew Limiter and Quadrature LFO while in self oscillation.


  • Two input crossfading mixer with CV control.

  • Voltage controlled Mode out for smooth sweeps between filter modes.

  • Individual filter outputs for low pass, band pass, notch and high pass filters.

  • Frequency CV input with attenuverter and additional V/oct input.

  • Voltage Controlled Q.

  • Ping input for striking the filter.

  • Sub range switch for filtering control voltages and quadrature LFO operation.
