The Pioneer DDJ-SX Digital DJ Controller includes the Serato DJ Software with specific buttons for FX, and advanced features like Beat Jump, Quantize and Slip mode. Its full-sized jog wheels deliver a perfect scratch response, and illuminated cue point markers provide easy control, without viewing the laptop screen. With blue backlit LEDs, the user receives visual references of currently playing modes and pre-set cue points. Using the slip mode, live edits can be made while the track is muted, and the track plays from the exact point when the jog wheel is released.
