I love this thing, it's seriously the most legitimate iPad beat making app on the market today. First off, the app is easy enough to just turn on and start playing or –if you're the meticulous beat maker-type– you can tweak the pre-made sound samples to infinitum or craft your own samples to build a new sound collage. I must warn you though, if you want to go beyond a basic EDM track, there's a slight learning curve but it's worth the effort.
