NoteButton

This is an example that demonstrates the use of MIDI Note Buttons that can be used for triggering samples, mute/solo/rec buttons, play/pause/stop buttons, etc. It can control almost any push button control in your DAW software.

Boards: 🛈
AVR, AVR USB, Nano Every, Due, Nano 33 IoT, Nano 33 BLE, UNO R4, Pi Pico, Teensy 3.x, ESP32, ESP8266

Connections

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

Behavior

Note numbers use the Scientific Pitch Notation system, where A4 is 440 Hz, and C-1 is 8.1758 Hz. See MIDI_Notes for a table of MIDI note numbers.

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.
