With the looming release of DJ Hero this fall, becoming a virtual DJ has never so many options. New from DJ-Tech is the DJ Mouse ($80) and it is designed to work with the company’s own Deckadance software for the Mac and PC. The main component of the DJ Mouse is its backlit multi-function jog wheel that allows you to control the faders and make scratch moves. The buttons on the mouse can be programmed to trigger samples and loops, set up cue points, and various other commands. There is also a regular scroll wheel so you can use it as an everyday mouse in other applications. Seems like a cool but pricey addition to the software, it could be the final touch to add that level of immersion you’ve been looking for.
