I have a Komplete Kontrol S49 MK2 Native Instruments controller I'm selling. Although it is fully functional, purchaser will have to order a new power cable for it, unless you have a 15v - 1.2A lying around. It connects to your computer via standard USB connection, I do have the cable for that which will be included. See pictures below, its in excellent condition. A massive upgrade for anyone who producers their own music and/or performs live with software like Ableton.
