Step 17: Wire the potentiometers to 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
