Both filters feature voltage control of cutoff frequency (±12V) and resonance (±5V). The resonance goes to self-oscillaton and the 1V/ocatve tracking works well over 4 octaves.
Each filter has individual outputs for lowpass, bandpass, highpass and notch. The State function controls (also with ±5V-CVs) the behaviour of both notches simultaneously but with opposite effect - When one core’s state is swept fully low pass the other core is fully high pass. The special feature is in the routing of the filter cores if both filters are used together: the notch output of the1st filter is normalized to the 2nd filter's audio input. If you turn the state control not only the state of the first noth will be chaged but also the whole behavoiur of the second filter. Now imagine this with feedbacks and experimantel modulations of the state parameter ... can get pretty wild in our opinion 8).
Because of different input and output responses the sound of the thwo filters is different which is useful if you want to use the module as two independent filters.
One common State-CV input for both parameters.
Each filter has CV inputs for cutoff frequency and resonance, an audio input, lowpass, bandpass, highpass and notch out.
