The Pioneer XDJ-R1 is a new all-in-one DJ system that can be used in many different ways and using many different combinations of media for music playback. The Pioneer XDJ-R1 can function as a two-deck DJ controller that can work with almost any DJ software of your choice (comes bundled with Virtual DJ LE). The XDJ-R1 can also function as a true standalone two channel DJ mixer, it can playback audio files directly from on-board USB flash/hard drives, and it can even be used in conjunction with Rekordbox and Remotebox in order to wirelessly control most of the DJ functions using compatible iOS & Android Wi-Fi enabled devices that are running the Rekordbox Pioneer DJ library software. The XDJ-R1 goes even a step further than the XDJ-AERO we reviewed late last year by adding dual CD slots in the front of the XDJ-R1 to allow users to playback music from CD's. All of these functions can be performed on each deck individually meaning the DJ has the choice of using the XDJ-R1 in hybrid mode to mix between different tracks in various different playback modes.
