Transposer

This is an example that demonstrates the use a Transposer to transpose the note events sent out by NoteButtons.

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 buttons will be enabled automatically.

Behavior

Mapping

Route the Arduino MIDI port into a synth to play the notes.
