The Dual Dreadful VCF is a dual filter with cutoff, resonance, and CV input with attenuation per channel. The filters have a shared Spread control on an attenuverter that causes the cutoff frequencies to move in opposite directions. Spread can also be controlled by CV.
Channel 1 Audio and CV inputs are normaled to channel 2
A mono signal into channel 1 will go through both filters in parallel.
12dB/oct filter slope
Can self oscillate at high resonance
High resonance does not lose bass response.
