Korg Delta / Poly-61 Filter Adaptation

The Delta VCF is back in Black Panel! And is the same circuit as all of my previous versions, and skiff/boat-friendly. Delta VCF is a faithful adaptation of the Korg Delta synthesizer filter in Eurorack. The lowpass circuit was also found in the Poly-61. And uses the same obsolete 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.

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/ a MIX pot.
Setting the MIX fully CCW or CW 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.
