Numark has put their stock behind Serato DJ software for the most part, but there are probably a few software choices this will work with

Another brand did not support the proposed software.

The software of this unit is FREE, and that is SERATO DJ INTRO

Integration between controller and software is flawless, of course, but the software itself is very limiting; it only outputs sound through the the outputs on the controller, which means I can’t really use my Bluetooth party speaker with it

So: nice hardware, does what it's supposed to, not from every computer, and not with free software.

To get the free software you have to registrar is with Numark

Virtual DJ is a better software for what I do, but you need to buy a $50 license to use it with this controller
