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. You can play for hours but also produce high quality tracks of any music style within minutes. Check the support page (2beat.io/oscilab) to see a 2 minute video, watch and hear for yourself what's it all about.
