The SVF is a 2 pole 12dB state variable filter providing low pass, band pass, and high pass outs. The filter has 2 audio inputs, but channel 2 is jumper selectable between standard audio in or Ping-able operation. The 2019 revision also adds improved cutoff and resonance response and attenuversion to the ENV in(CV in) through the above CV pot. The 1V in provides another un-attenuated exponential approximated CV in. Contrary to what the panel says the filter does not track 1V per octave and is not temperature compensated.

At the 1V in, +10v will open the filter completely if the cutoff pot is CCW(counter clockwise). With the cutoff knob at noon the filter can be opened with +5v or closed with -5v. CV input at the ENV in is dependent on the CV attenuverter knob.

There are also several jumper selectable modes for max resonance, self oscillation or no oscillation based on the setting of the resonance pot.  According to the jumper configuration, the filter is capable of clinical and clean, to juicy and drippy, to low pass gate sounding plonks, to screaming chaotic resonance. When set to self oscillation mode, the filter can produce a sine like wave with no input and a trapezoid like wave in the max resonance jumper setting. In max resonance mode, the filter output can exceed 10Vpp. On the newest version, there is a trimmer on the top pcb to set the lowest cutoff frequency.
