Custom-MIDI-Output-Element
This is an example that demonstrates how to extend the library using your own MIDI Output Elements. The example declares a MIDI Output Element that sends MIDI Note events when a push button is pressed or released. It's a simplified version of the NoteButton class.
- Boards: 🛈
- AVR, AVR USB, Due, Nano 33 IoT, Nano 33 BLE, UNO R4, Pi Pico, 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 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.
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.
