SVFs is a dual voltage-controlled State Variable Filter. Each filter has 1 signal input, 2 control voltage inputs with one attenuverter, and 3 signal outputs: Lowpass, Highpass, and Bandpass.

When the resonance control is turned fully clockwise, the filter will self-oscillate, yielding a sine wave on the three outputs, 90 degrees out of phase with each other. Each filter has a CV input that tracks v/oct, allowing many techniques including use of each as sine wave oscillators for a mini fm voice!

SVFs' signal inputs are DC coupled, so the filters can process both audio and control voltages. Great for making slewed and resonant envelopes and sequences. With multiple outs, try feed one back into a CV input for new extreme sounds!
