The Voice of Saturn Synthesizer was the first device I created that bears the Voice of Saturn name. It came out of my own experimentation with the venerable 555 timer IC and was the result of some circuit bending of some known schematic ideas, the basis of which being the Atari Punk Console.
Some changes to the build doc:
R11 is b500
R12 is B500
R7 is A100
Instead of the vactrol on the last build i just wired cv1 and cv2 into the cv pins on jp11 and jp14 with a diode for negative voltage protection. kinda does some fun stuff but definitely cv control could be improved on. Also the LFO type/depth connections are kinda hacky and could be worked on.
