The filter sounds really good and very classic like an old ARP, having a simple yet effective layout.
It has controls for cutoff frequency and response (= resonance); the third potentiometer (Amount) is an attenuator for the amount CV input, turned fully clockwise it has a scale of 0.5 V per octave..
The cutoff frequency can be modulated by two CVs at the "frequency inputs" sockets.
Audio: 2x signal input, 2x signal output
CV: 1x amount input, 2x cutoff input
