Ableton 9 loves this app!
It took a little fanangaling to get everything working, but this is one of my favorite apps. If youre using Live 9, there are three things you need to download on your Mac in addition to this app on your iPhone/iPad.
Get the TouchOSC Editior, TouchOSC Bridge, and LiveControl version 1.
Most links for LiveControl are for version 2, but version 1 is what you need for Live 9.
