I am looking for the BEST DJ apps you can get on the iPad. I have been using free ones that only let you play and switch between music on 2 decks. I want something that will let me create my own beats, edit music, and basically make my own tracks. One thing i have really wanted to do is get the take the beats out of rap music and add techno beats to the rapping. are there any apps that let you do that? I heard the best app is called Mixr, but i could not find that in the app store...is it out?
