It supports midi, so you can use it in anything that supports midi, which would be ableton or just abut any audio app these days. Your still going to have to map it by hand though just like any other controller that doesnt have a map built into ableton.
It doesnt have a crossfader on it, so if you wanted to use it as one you would have to map one of the knobs to the ableton/traktor crossfader...
