This synth is based on the Voice of Saturn, but with a few changes. Besides improving some of the components, I’ve gotten rid of all the complicated wiring diagrams, making it a simple synth for anyone to build that is also compatible with a Eurorack system. It's got an LFO out, two CV inputs and main output for the synthesizer
