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

• 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 Note On message is sent for note C4.
• When the button on pin 5 is released, a MIDI Note Off message is sent for note C4.

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.
