Step 17: Wire the potentiometers to the Protoboard.
Daisy chain the positive and ground leads from the potentiometers together, then insert them into their respective rails on the Protoboard.
Wire the signal wires of the potentiometers to Analog 0-4, I kept the grain and frequency knobs on the first row of knobs, and the sync knobs below them.
Again, the signal wires sync accordingly:
Analog in 0: Grain 1 pitch
Analog in 1: Grain 2 decay
Analog in 2: Grain 1 decay
Analog in 3: Grain 2 pitch
Analog in 4: Grain repetition frequency
