PBPotentiometer Class Reference

#include <MIDI_Outputs/PBPotentiometer.hpp>

Detailed Description

A class of MIDIOutputElements that read the analog input from a potentiometer or fader, and send out 14-bit MIDI Pitch Bend events.

The analog input is filtered and hysteresis is applied for maximum stability.
The actual precision is "only" 10 bits, because this is the resolution of the built-in ADC, and this is the default resolution used by the Mackie Control Universal protocol.
This version cannot be banked.

Examples
Pitch-Bend-Potentiometer.ino.
