Vortex Sound Research

i have a td 3 synth and i want to buy the rd 6 to have some fun but what are the cables that i need i play my audio through a frostbite thing that goes to the pc

long story short what are the cables that i need to use to get them together i watched some vids but no one says what cables you need or im am just paying attention correctly ( attention spam is somewhat low)

thanks in advance
