@Colesy > You have two options -- one is to use it as a controller (like the DDJ-RX) with rekordbox in performance mode, the other is as a stand-alone unit, which can use either a USB drive or rekordbox in EXPORT mode as the source. Unlike the original XDJ-RX, there is no ethernet port on the RX2, so you do connect it via USB, and it creates a network bridge (with the proper driver installed), allowing you to "link" it in the same way.
