Works Perfectly!
This software is awesome for remotely controlling live!! I got the bundle version back in December 2014. I have it on my iPad 2 and iPhone 6 Plus. I also had it on an iPhone 4S before I upgraded to the 6 Plus. As long as you have the latest server release, have Reinstalled the Ableton Script, and properly setup Abletons Midi Control Surface preferences, you shouldnt have any trouble with touchAble via USB or Wi-Fi. FYI, I have had server/script issues with the Beta versions of Ableton Live 9 Suite. So, I avoid using touchAble if Im Beta testing. However, if youre using an official release of Ableton, which is what I use live, then you should have zero issues. Again, this software is amazing and works perfectly!
