Add more knobs and buttons to the controller

Hi, I am very interested in learning more about this arduino to make a midi controller for ableton. I am confused when I want to add another knob to assign different maps in ableton. How to add more knobs and buttons to the controller ? Best regards and thanks you

Well first you have to make a controller. Then get the code for it working. Then post circuit diagrams and the code here.

Then we might be able to help with adding more knobs and buttons to it.
