DJ digital controllers have made huge improvements in recent years and have revolutionized the DJ market. Every major company, including Pioneer (DDJ), is now producing controllers. The main advantage of DJ controllers is that DJ’s no longer need to carry around cases of CDs or vinyl records, and all controls surfaces are packaged in a streamlined unit. For mobile DJs carrying less gear to a gig is priceless. All you need is a laptop, a USB cable, a power cable for some units, and a controller and you are ready to rock the party. You don’t need to bring a mixer, CDJs, and turntables. Controllers allow DJ’s to play any digital music file like MP3, ACC, or WAV files. Another plus is if someone asks for a song that is not in your library you can download the track if you have access to WiFi. The price of DJ controllers continues to drop and there are many professional software choices like Serato, Traktor Pro, and Virtual Dj to harness the power of DJ controllers. Controller manufactures are partnering with software developers and many of the new controllers are pre-mapped. This means all you have to do to setup the unit is run the install CD, plug in the controller, and you are ready to start mixing. The new line of DJ controllers will change the DJ business forever.
