Do you have a gaming controller?

A few weeks back, my MIDI controller broke. While procrastinating on getting it fixed, I found my gaming controller sitting idle and had an idea. I made a simple website that allows me to connect it and play a piano through it. I've mapped the joysticks to change octaves, and other buttons play notes (placed strategically to make chord combos).

I've been having fun with it, and wondering if I should make this website public. What do you all think? Would you be interested in trying it out? Do you have a controller to begin with?

(I did come across DAW setups with plugins that do the same, but I prefer a DAW-less setup)
