It’s the simplest remix app we’ve ever tested. Instead of making conscious decisions about what to put where, you simply grab your iPhone, iPod Touch, or iPad and start dancing around. The phone interprets your movements in the following ways in order to apply effects to two songs at the same time (thus “crossfader”):
Those images are from the tutorial; here’s what the app looks like when you are actually remixing/mashing up the songs. Each of these two blocks represents one of the songs you’re working with; you can double tap the screen to switch one of them out for another:
It pretty much always sounds great, which is partially due to the music that’s included in the app — songs and stems from a pretty extensive crew of dance jam makers:
A-Trak, A$AP Rocky, Aniki, Steve Aoki, Baauer, Julio Bashmore, Daft Punk, Deadmau5, Dillon Francis, EPLP, Missy Elliott, Estelle, Fatboy Slim, Feed Me, Flosstradamus, Wolfgang Gartner, Groove Armada, Hard Rock Sofa, Calvin Harris, Henrix, Heroes X Villains, Joker, Justin Jay, Lil Wayne, Little Dragon, Loz Contreras, Ludacris, Marco Plex, Martyparty, Hudson Mohawke, Mord Fustang, Pendulum, Phosphorr, Ramadanman, Red Carpet, Robbie Rivera, Scientist, Thomas Schumacher, Skrillex, Spencer & Hill, T.I., Third Party, Trina, Tube & Berger, Usher, Armand Van Helden, Kanye West, and The Winstons
That’s plenty to work with at your next dance party, but developer Devin Chalmers of DJZ, which made the app, mentioned that upcoming versions might include the ability to import your own music into the app in order to add that into the mix as well.
“All our loops are bundled into the app, but we’re trying to come up with the best way to let people add their own music and make it sound awesome,” said Chalmers via email. “Right now, it’s almost impossible to sound bad.”
DJZ recommends plugging this app into the speakers at a party and getting everyone to dance along with whatever comes out of them, which should work just fine. The app lets you record your remixes and post them to SoundCloud; here’s what happened when I started up the app and started dancing around with my iPhone in my hand, with no pretense of trying to do anything in particular to the songs:
And here’s a video demonstration from DJZ:
