With midi_keypad.ino - how to add a midi "feedback" to turn on a button light

[Argon5]

Hello,

This is my very 1st time on GutHub and don't know if this is the correct place for this.

I was using the midi_keypad.ino with some PC software and it works great for sending CC code and triggering things within the PC software.

I was wondering how I can implement receiving CC code to turn on (or even change the color) of the button lights on the Trellies M4.

Thank you.
