What annoys me is these Ableton DJ sets get billed as "live pa" when it`s hardly that.
Little effort goes into teh preparation or performance, and it tars the rep of people who do do it properly.
When I play live, I`m running about 12 channels of audio plus vsti and fx, and sometimes, during a live pa, I get it wrong, cos I`m pushing myself.
It takes about a 2-3 weeks to prepare a pa which will only get played a couple of times.
It`s pretty annoying seeing these lazy plebs knocking a 2 track ableton mix together as a live performance, when I could tutor my girlfriend in ableton in a day, and get her to do more interesting 2 tracks sets than most of the ones I have heard.

If your gonna DJ with it, then I think as you have all that extra time from not having to beatmatch to work it.
Get loads of loop grooves, split down the full tracks used into sections so they can be resequnced etc.
Do some ****ing work.
