Features
A 4-Pole, 24dB/Octave state variable filter designed exclusively for this system by Jim Patchell; Synth DIY guru.
1V/O in allows for keyboard tracking of the cutoff frequency. This is a fixed input setting that can be set using a trim pot on the circuit board.
Mod In jack (above the 1V/O jack) provided for CV input control/ modulation of the filter cutoff frequency. The amount of effect this input has on the filter frequency is determined by the CV amount control immediately above it.
Mod Amt control allows for variable CV control effect on the filter cutoff frequency.
Audio In jack for audio source input to the filter.
Frequency control allows for manual "tuning" of the filter cutoff frequency.
Resonance control allows for manual control of the filter band width from broad to self-oscillation.
Simultaneous, Independent outputs for Low Pass, Band Pass and High Pass filter output modes.
