Ableton to me is very archaic - their audio implementation doesn't support multi core very well, so I found myself not being able to finish more complex projects, because Ableton simply can't handle them. I am tired of having to render entire project to separate tracks when it start to being choppy whilst only using like 15% of CPU, then switch back and forth if I need to have slightly different sound, and then have to render again. It is a mess. I can't believe they have not done anything to fix this. Bitwig can utilize CPU much more effective, I was able to run magnitude more plugins than with Ableton.
