Paid version comes with Launchpad Pro features 03/03/17
Developer, Alexander Nowak, tells us that Launch Buttons, an app that looks like a Launchpad S and controls Ableton Live via the Launchpad95 script, is now available for free on iOS and Android. He says that all of the (former) full version's buttons and functions are available for free, probably because the $4.99 Plus version now supports RGB pads, a Launchpad Pro layout and is compatible to the Launchpad Pro95 script.
Alexander said, "The free version's only purpose was to find out whether your wireless network supports the paid version - now it's become a reasonable controller."
