Wave Folding Circuit (Buchla 259 Wavefolder)

Demo of circuit from "Virtual Analog Buchla 259 Wavefolder" by Esequda, Pöntynen, Välimäki and Parker.

oh super neat! I'm going around trying to find the simplest circuits for processing signals, gonna see if I can make something close to an open source analog synth

Woah, I just independently came up with this same idea using op amps and transistors.

“Creates very interesting sounds” (doesn’t demonstrate any of them). Show us!!! I want to learn!!😢

It's quite hard to read the schematics. What Opamps and what resistor values are used? Or do you have a link to the schematic? Thanks!

[@MikeFikes]

The schematic and component values are in the paper "Virtual Analog Buchla 259 Wavefolder." I think I used some simple jellybean op-amps (probably just μA741s).
