Arcade Buttons for PO-12?

so i recently remembered watching a video of someone using something resembling a MIDI Fighter. 16 arcade style buttons along with the 7 extra buttons for functions. i’d like to do this myself for my PO-12 but i have no clue in hell where to start with something like that, or if it’s even worth it. what do yall think?
