Of the many, many iPod accessories that have crossed my path, one of the seemingly coolest was the . Of course, once we found out that the iDJ lacked pitch control--a critical feature that allows DJs to slow down or speed up tracks in order to control tempo and match beats more effectively--the shine quickly wore off. Enter the iDJ2. The second version of the iDJ not only adds this important capability but also does away with the need for a second iPod--you require just a single iPod to start mixing tracks. But if you want to hook up another 'Pod--or just another mass-storage device, such as an external USB hard drive--you can do so through the iDJ2's rear-panel USB ports. There are also line inputs for audio sources such as mics and more traditional turntables. Other features include seamless looping; a multiline backlit display; real-time visual cues such as waveforms; the ability to play two songs from the same iPod; scratch-and-search capability via two large jog wheels; XML playlist support; and USB keyboard support. Sounds pretty cool, huh? Yeah, we think so too, which is why we've requested one. Stay tuned for our full review.
