Program-Changer

This is an example that demonstrates the use of MIDI Program Changers.

Boards: 🛈

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

Connections

• 2: momentary push button (to ground)
• 3: momentary push button (to ground)
• 4: momentary push button (to ground)

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

Behavior

• When the button on pin 2 is pressed, the MIDI Program for "Acoustic Grand Piano" is selected.
• When the button on pin 3 is pressed, the MIDI Program for "Rock Organ" is selected.
• When the button on pin 4 is pressed, the MIDI Program for "Electric Bass Pick" is selected.
