Oscilab

Amazing groovebox that gives you an hypnotising music-making experience. It's an innovative step-sequencer and MIDI controller that lets you make unique loops and melodies. You don't have to be musical to get up and running - just randomly pinch and swipe away until something catches your ear, but also there are plenty of advanced synthesis features here too for the savvy musician.

The app is easy to pick up, it is fun to sketch out ideas, has low latency and is actually usable compared to 98% of the other audio apps for Android. You can play for hours but also produce high quality tracks of any music style within minutes. Be the DJ at your own party, leave Pandora for the noobs! Buy, explore, enjoy!
