Slide Potentiometer (Fader)
The fader functions as a mechanical voltage divider where a metal wiper contacts a carbon track; oxidation or wear on this track creates intermittent resistance. The internal microprocessor interprets these electrical fluctuations as rapid MIDI Continuous Controller (CC) messages, resulting in the reported 'MIDI noise' and audible parameter jitter. Replacing the worn potentiometer restores a stable analog voltage for the Analog-to-Digital Converter to process.
