Looking for a way to move the fun and functionality of the iPad’s Djay app over to your Mac? The Gemini FirstMix USB DJ Controller ($100) is a good place to start. Thanks to a simple USB connection, included Cross LE DJ software, and compatibility with a number of Mac DJ apps—including the Mac counterpart of the aforementioned Djay—it can accomodate DJs of any skill level.
Features include a browse function for navigating through folders and tracks, a Sync feature for automatic beat matching, touch-sensitive jog wheels, bass and treble adjustments, the ability to splice in effects, reverse play, and more. Sure, the iPad can do a lot of those things, but sometimes it’s better to have real buttons than virtual facsimiles..
