From the project
Space Coast Synthesizers - Stereo POGO Filter
POGO is a stereo filter bank module (48HP) being developed by Space Coast Synthesizers. The VCV Rack 2 plugin in this repository is the working software prototype and ground truth. Analog hardware design is reverse-engineered from it.
POGO routes stereo audio through a deeply modulated filter bank: a pre-gain stage, a voltage-controlled VCA, a stereo LP filter with tilt (LP1), three independent bandpass resonators (BP1/BP2/BP3) with per-group distortion, a HP filter, and a final LP filter (LP2). A dual triangle LFO feeds a central mod bus with 18 attenuverter CV destinations (plus a raw VCA…
