THIS APP DOES NOT PLAY AUDIO BECAUSE IT'S A MIDI CONTROLLER FOR ABLETON

Launch Buttons is a MIDI controller that lets you perform your tracks wherever you go. You don't need to carry your expensive gear; your phone/tablet is just about enough. Works with virtually any DAW after a very simple set up. Ableton Live + Launchpad 95 script is recommended for this MIDI Controller emulation to work.
