Im pretty new to all of this and got myself a 2020 MacBook pro and have to second hand kontrol s4 tractor decks. I got them off somebody I know and has proven they 100% work. I have power to the decks and have the Traktor pro s4 software. Ive tried numerous cables off different places and the decks and MacBook aren't responding to each other.Can anyone recommend what to do or what cable I'm missing or I'm missing something in the settings.
Many thanks.
