AppAdvice has teamed up with IK Multimedia in order to offer you a chance to win one of five promo codes for DJ Rig ($1.99) for iPhone and iPod touch.

DJ Rig is a full-featured DJ mixing app that finally allows you to ditch all of that expensive equipment and get right down to making sweet music no matter where you are.

The app allows you to play songs from your personal library and then mix, scratch, loop, and crossfade until your fingers hurt. In landscape orientation you’re able to utilize two decks and scratch with multitouch controls. In portrait orientation you’ll be giving up a deck for quick access to effects, loops, and a variety of other options. Either way, you’ll have no problem finding your way around.
