I want to be able to connect my midi Keyboard up to the computer and then output the audio to light up LEDs. I am wondering if anybody has done this or how to go about it? Ideally I would love to be able to manipulate the code so that whichever keys i am playing i can control the output effects (colour, fade, etc).
I know I will need to use an arduino as well but I am just not sure how to do all this. Any help would be greatly appreciated.
