Of diodes and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on the dial. Set to zero if you wish), that you can change the software is covered only if you can create a D-shaped shafthole if desired.
