Dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the coarse knob to fix tuning range updates the potentiometer pads and trace routing to de-bodge the pots.
