Numark Mixtrack Pro II Digital DJ Controller *READ DESCRIPTION BEFORE PURCHASING. This is just the unit (no cables or any other accessories included). There is a pitch fader piece missing on the left. Whenever I plug it in, all the lights come on but I could not get it to work with my serato or other dj software (no sound or anything). I did run the audio and midi monitor best on Mac to see if the controller is present and it is, Im not sure if this a software or hardware issue so bare that in mind.
