Launch Buttons is a MIDI controller that lets you perform your tracks and lightshow covers wherever you go. You don't need to carry your expensive gear; your phone/tablet is just about enough. On my website, I provide a MIDI Remote Script for the use with Ableton. The script is based on Henri David's Launchpad Pro95 and also is compatible to the original Novation Launchpad Pro.
THIS APP DOES NOT PLAY AUDIO.
This is the Plus version that provides more colors, 16 more function buttons and 16 freely assignable knobs.
