Serious DJs tend, as a rule, not to use iPads. It’s a bit contrary to their stated mission of playing back the hits on vinyl, not via MP3, and there are other abstract arguments that aren’t worth getting into here.

But if you just want to pretend DJ, or you have a wedding that you don’t want to bring all your gear to, you can deploy the suction cups with Scratch 2 Go.
To be fair, Scratch 2 Go is designed to turn the various DJ apps for iPad into something a bit easier and more professional to use than just poking at a touchscreen.
The kit sticks to the screen with suction cups and includes a cross fader, two turntables, and some pots to play with.
Granted, these aren’t professional tools, but anybody who has used music-mixing apps or DJ apps will appreciate getting something that makes them a bit easier to use. Knobs in particular are a terrible idea on touchscreen and yet far too many apps are enamored of them. The Scratch 2 Go will be available later this year for $40.
