Korg Delta/Poly-61 Filter Adaptation

The Delta VCF is a faithful clone of the Korg Delta synthesizer filter in Eurorack. The lowpass circuit was also found in the Poly-61. And uses the same OTA chips and dual transistor as the original Delta. It is all analog, no DSP, so it will warm up any signal run through it.

This 8HP version is the same circuit as all previous versions, and skiff/boat-friendly

FEATURES
Two filter slopes: original 4-pole, and 2-pole.
Two filter modes: lowpass or bandpass.
Illuminated Frequency and Resonance Bourns Slider pots.
Mix together two different input oscillators at the input jacks w/ signal attenuation/gain pots. These inputs can overdrive the filter.
Modulate the filter cutoff with two different input control voltages w/ signal attenuation pots.
Trim pots for adjusting frequency and resonance range. Some of you out there may want to give a little boost to the resonance trimpot on the PCB. Doing so will make this thing scream and howl a little harder.
