Many bugs with Ableton; poor support
I was excited to use this app, but the set up with Ableton was very tedious and had to figure a lot of stuff out for myself; eventually had to resort to downloading other software just to get it to work at all. Everything worked except the x/y axis controllers, and when I contacted support, it took over a week for them to get back with me. They just said "we just want to confirm that TouchOSC works without OSCulator installed" and then referred me to another type of software called Live Control. I replied that it didnt work at all without OSCulator, and havent heard back from them since. I have moved on and now am using Lemur.
