The differences between the Pioneer CDJ-800 and the Pioneer CDJ-1000 include: No hot cue function on the CDJ-800 (the 1000 will store cue information in its permanent memory) Reverse function is controlled by a button, on the CDJ-1000, it is controlled by a switch. Auto Beat Loop Uses 4 timing buttons to instantly create perfect 1, 2, 4, or 8 beat loops. Quick Return Enables a track to return instantly again and again to a cue point just by pressing the surface of the Jog Wheel. "Wide" Pitch Control DJ's can use the +/- 100% pitch control range to create new sound effects from opposite ends of the sound spectrum and also to BPM match completely different tracks. When a loop has been produced manually with the loop in and loop out buttons, this feature allows instant 1/1, 1/2, 1/4/, 1/8 beat cuts of the initial loop. Ground-breaking functions are packed inside a compact and durable casing that makes the CDJ-800 ideal for surviving life on the road and for playing-out in tough club environments. A world-beating combination of new and proven features, the CDJ-800 feels like a vinyl deck and delivers digital player power to home-DJs, mobile professionals and superstar DJs
