This is a Kosmo version of the Kassutronics Wavefolder . It includes an extra jack and pot for a Symmetry (Odd/Even) CV and another extra jack for a second VCA CV, as described near the end of the Kassutronics build document.
The PCB is built according to the Kassutronics instructions except for the above additions and:
- The jacks and pots are panel mounted
- Since the -9 V regulator (LM7909) is hard to find, I substituted ±8 V regulators (LM7808 and LM7908)
