Yeah with the hammer-on-pull-off thing I was referring to the last little ornament that appears for example at 0:39. Hard to say what kind of processing is used for the intro, sounds like it could just be manually chopped. There could be some reverse sample in those rhythmic parts, but again that's just guessing. Anyway, from the part starting at 1:06 it's pretty obvious that some sort of glitch plugin is used. I've never used Ableton, though, so can't think of any obvious ways how it might have been done.
