The Filter is a voltage controlled, analog, state variable filter. The state variable topology was chosen because it allowed us to produce a very smooth and natural sounding filter, in addition to offering several other modes of operation, each with a unique sound and energy all their own.
Controls (Top to Bottom)
Q Pot: Adjusts the resonance (Q) of the filter.
FREQ Pot: Adjusts the Frequency of the filter.
L-H Pot: Sweeps between lowpass, notch, and highpass filters.
QCV Pot and Jack: Resonance (Q) control voltage input and attenuverter.
FCV Pot and Jack: Frequency control voltage input and attenuverter.
1-Q Switch: Switch between Gain to 1 (VCA Mode) and Gain of Q (Standard Mode)
F-O Switch: Switch between Filter and Oscillator Modes
LOW Jack: Lowpass Output
L-H Jack: Output based off of the L-H Pot
HI Jack: Highpass Output
Power Usage: 31mA
