Multiple-Control-Change-Potentiometers

This example demonstrates the use of MIDI Control Change potentiometers that can be used for changing effect parameters, volumes, pan and balance controls, etc. It can control almost any knob in your DAW software. This example shows how to define multiple potentiometers using an array.

Boards:
AVR, AVR USB, Nano Every, Due, Nano 33 IoT, Nano 33 BLE, Teensy 3.x

Connections

Connect the left terminal of the potentiometers to ground, and the right one to VCC.

Behavior

Mapping

Select the Arduino as a custom MIDI controller in your DAW, and use the MIDI learn option to assign the potentiometers to a function.
