When you need some more instruments in the mix, take to the 16 backlit rubber pads for samples, drum kits, and other basic MIDI controls. As the Numark Mixtrack Pro II DJ Controller is USB-powered and class-compliant with Mac and PC, all you have to do is plug in and begin mixing. You will receive Serato DJ Intro software as a part of your order, but if you’d prefer to use your own program, the Mixtrack is fully compatible.
