Control Surface

MIDI Control Surface library for Arduino
|
This example demonstrates how to attach custom callbacks to Note or Control Change MIDI Input Elements.
If a MIDI Note On event for note 0x3C (C4 or middle C) is sent, the built-in LED will light up at full brightness, if a Note Off event for that note is sent, the LED will light dimly.
(A Note On event with a velocity of zero also counts as a Note Off event.)
Route the MIDI output of a MIDI keyboard to the Arduino's MIDI input. Then play a middle C on the keyboard.
