BackCLIMB.png 8576ad9482 Added input resistor for sync; placed everything on PCB choices could also do midi-over-usb buy a Korg MS-20. ** that one fails due to referer checks 943ef1409b Fix getting a bunch of wires backwards Fix floating pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary? Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF 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 top (mm) hole_dist_top = 2.5; //mm first_col = 10.1+center_adjust; //mm second_col = width_mm/2; //mm third_col .
