Look up onNLC ResonateBuilt and tested by meThis is based on the core circuit of the Korg 3100 Resonator.The main difference of this version is that it has 4 VC bandpass stages and a feedback control, the original has 3 stages and no feedback. The 4 VC bandpass stages can be controlled by a single CV on input 1 (with an attenuator) or individually with each of the 4 CV inputs.The CV processing sub-circuits are greatly simplified from the original Korg version, simply using op amps to drive the vactrols. The 2 inputs are summed together. Out 2 is an inverted version of Out 1.Warning: This is a weird module.
