Dual-MIDI-Interface

This example demonstrates how to group together two or more MIDI interfaces, so you can send the MIDI output over both MIDI USB and 5-pin DIN MIDI, for example. MIDI input is received from all interfaces as well.

Boards:

AVR USB, Due, Teensy 3.x

Connections

• A0: wiper of a potentiometer

Connect the left terminal of the potentiometer to ground, and the right one to V_CC.

Behavior

• When you turn the potentiometer, you should receive MIDI Control Change events on both the Serial MIDI interface and the USB MIDI interface.
• When a MIDI Note event for middle C is received on either MIDI interface, the state of the built-in LED will change accordingly.

Mapping

• None
