While a filter might be the basis for the Serge Quadrature Oscillator design
(I honestly don't know - haven't looked at the board), there is no input for
filtering. Also, the frequency is limited to 500 Hz even with external
control voltage inputs.
This is an excellent module for panning control however since it has the
built in VCAs/attenuators and the Serge VC pan does not have a CV
attenuator.
