Ableton Forum

Well, I guess the topic pretty much sums it up.
It would be good to have a propietary Ableton app (as Logic's remote for e.g) that can handle both session AND arrangement view (the latter in particular), I haven't seen any of the third party apps available (not even touchable pro) provide this kind of functions/support.
It would also be good to have it work with no extra installs/drivers and stuff.

Maybe this app will help you partially

otherwise you can assemble whatever you want with TouchOSC

Both awailable for Android as well.

Does these support locators and or arrangement view?

I can't believe we're in version 11 and still no native mobile app for transport control at least.
