Hello guys! I recently discover on my garage, a keyboard CASIO CTK-501. 61 keys, MIDI to all keys and "Volume" buttons. And i want to turn it in a bigger controller, adding knobs, faders and pads to interact with Ableton Live. But i don't know what kind of parts, connections and what i probably should. So, what parts i need? What more information you guys need? Thanks a lot!
