Pioneer's DDJ-SX DJ Controller utilizes the Serato software as the basis for its control layout and ergonomic design, taking advantage of the software's features and integrating special trigger pads and controls. Pioneer has also implemented larger jog wheels for precise mixing and scratching, multiple inputs for expandability, and 4-channel mixing flexibility. Mixing with Serato DJ Sold as a complete system that includes the controller and new Serato DJ software, the DDJ-SX provides additional features to provide direct, tactile control of the software's capabilities, which include a four-deck sampler function, dual deck control, slip mode, FX mode and more. Serato DJ has a brand new look and a greatly improved software layout, optimized for simplicity and a great experience. The new interface also offers two and four deck view modes for four deck controllers, alongside improvements to the cue point and looping controls, which now allow you to display either 8 cues, 8 loops or a combination of both depending on how you perform. MIDI mapping opens the software up to be mapped to a secondary MIDI controller to take full advantage of all Serato DJ's features in your performance and create your own unique workflow. 4-deck mixing has never been better with the ability to easily create your own special blends of tracks, instrumentals, and vocals without the pressure of keeping everything in time. Less time making it work, more time at the party. Dual Deck The DDJ-SX enables two tracks to be controlled at the same time, allowing scratching or setting and recalling hot cues on both tracks as if they were performed on a single track. Slip Mode While activated, Slip Mode silently continues song playback during a performance loop, scratch or hot cue and resumes audible playback when the loop, scratch, or hot cue operation is ended, creating smoother and more seamless transitions. FX Powered by iZotope High quality FX newly developed by iZotope are available in Serato DJ. With the new effects, any DJ can apply more creative and more unique arrangement to their music. Additional functions include up to eight hot cue points can be set for each deck, as well as vertical waveform display for fast tempo syncing. Customized Control Layout Works as Great as it Looks The DDJ-SX can quickly access the multitude of features Serato DJ offers through its buttons, knobs, sliders and performance pads. Thoughtfully laid out to deliver the best DJ controller experience, its buttons and knobs are designed to match the applicable software functions perfectly. Performance Pads Pioneer added eight "performance pads" located below the jog wheel for four different functionalities: HOT CUE, ROLL, SLICER, and SAMPLER. Each soft-touch rubber pad illuminates in blue to enable users to quickly tap the pad(s) for each effect, with the output volume varying depending on the strength of each tap. Large Jog Wheels The jog wheels on the DDJ-SX are enlarged for more precise scratching and mixing. The resistance for each jog wheel was fine-tuned to provide users with the best "feel" and the shortest latency. The unit also features an "On Jog" display located on the center of each wheel to provide instantaneous visual feedback of playback status and the position of playing tracks. 4-Channel Mixer The DDJ-SX features an independent 4-channel mixer that can be used with other external sources such as turntables. Its master level meter provides instantaneous sound level adjustment as well as independent output controls with a display indicator for each channel when used as a standalone mixer. Aluminum Finish The DDJ-SX sports an aluminum top panel and a brushed aluminum finish for the jog wheels, for an optimal look and feel.
