The peaking control determines the resonance but also acts as a switch between filter or VCA. The resonance is strong and the filter self-oscillates very fast. A further control blends from low- over band- to highpass mode.
Because of the slow and inert Vacrols used in the circuit it is quite impossible to modulate the cutoff frequency with fast CV signals.
