Module A-102 is a reproduction of the legendary low pass filter design that uses diodes in the filter stage as frequency controlling elements resulting in "strange" resonance behaviour and frequency response as resonance and frequency are not independent from another.
manual control of filter frequency
3 CV inputs (CV1, CV2, CV3), 2 of them with attenuator (CV2, CV3)
input level control
resonance control up to self oscillation (depends upon the frequency setting for the A-102)
