A quick question (I hope).
I’d like to make a custom midi controller, with feedback from a DAW like Reaper/SunVox so that the colors of the buttons show what’s happening in the DAW.
I was concerned about having an extensive amount of buttons (I’d like a 4x4 button grid), and not having enough GPIO room for things like potentiometers and other inputs.
Question: with the plasma buttons, it seems like I can string them together and get addressable LEDs - do the inputs on the buttons all come through to the Pi on that single interface as well?
If so, I feel like that would give me plenty of GPIO pins for the other types of input I want (a joystick for an X/Y controller, rotating potentiometers and slide pots), etc.
Thanks for any and all pointers prior to buying!
