CCButton

This is an example that demonstrates the use of MIDI Control Change Buttons.

Boards:

AVR, AVR USB, Due, Nano 33, Teensy 3.x, ESP32

Connections

• 5: momentary push button (to ground)

The internal pull-up resistor for the button will be enabled automatically.

Behavior

• When the button on pin 5 is pressed, a MIDI Control Change message with a value of 0x7F (127) is sent for General Purpose Controller #1.
• When the button on pin 5 is released, a MIDI Control Change message with a value of 0x00 (0) is sent for General Purpose Controller #1

Mapping

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