With the advent of more powerful software and controllers, modern DJs really don't need to learn as much about spinning tracks as they used to. Now beginners are treated to automated cues, loops and beat matching software that take some of the art out of DJing. The latest bit of automation comes from Pioneer and its $249 DDJ-SB3 DJ controller. The unit adds a Pad Scratch feature that gives aspiring club monsters the ability to imitate eight different scratch techniques that were recorded by DJ Jazzy Jeff. Whatever track you're playing, the scratch will automatically match up with the right tempo with a simple tap on a performance pad.
