Root Locus

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 an interesting quadrature LFO while in self oscillation.
