I'd like to build one if these, it really gets a lot out of the IC: https://modularaddict.com/module-type/waveshaper/570-galore-dynamics-processor-pcb-panel-timo-rozendal

570 Galore - Dynamics Processor PCB/Panel | Timo Rozendal<https://modularaddict.com/module-type/waveshaper/570-galore-dynamics-processor-pcb-panel-timo-rozendal>
The 570 Gallore circuit was put together via Timo Rozendal with heavy influence from Thomas Henry's circuit literature.This is for a PCB/Panel in Eurorack Format

I have a couple of 570s I ordered in 2016 and forgot about. Is there simple circuit schematic I can follow to stand them up for experiments? I remember fiddling with one in the 80s to make a noise gate for my Radio Shack bbd board.
