Model: Cydonia Bi-phase Stereo VCF
width: 12hp
current: 83mA, -77mA

What does this module do?
The module has two filters, and two ota based vca's. Most of the controls are setup to control both filters with one set of parameter knobs. There is a spread knob that separates the resonance peaks between both filters. You can get cool vocal and nasal filtering with careful adjustment. The filters self resonate. There is a trimmer for each filter which allows you to adjust how much feedback you want.

There is a fancy cmos based logic control system to select the state variable outputs. DG412 modern analog switch is used internally. This analog switch is made for audio (-5v/+5). There is a 'reset' button to quickly go back to LP flavor.
