The 16 performance pads (8 per deck) provide Hot Cue, Auto Loop, Tracking, and Sampler functions, as well as Beat Jump, Roll, Trans, and Scratch Bank modes. The center panel of the DDJ-REV1 is a 2-channel mixer with a built-in soundcard. Each channel features a trim, a 3-band EQ, a two-way Sound Color filter (HP/LP), and a level fader. Beat FX can be triggered by the effects levers, which allow for momentary and locked effect positions. The controller can also control decks 3 and 4 with Serato DJ. The Pioneer DDJ-REV1 is bus powered and ships with a USB cable.
