_But_ - man is it far behind the modern DAWS like Studio One and Bitwig in the low-level fundamentals like plug-in isolation, multithreading, and flexibility in terms of your ability to offload frozen tracks from RAM. This puts a bottleneck on the max size of a session before it becomes unstable and unusable. Even with 32GB RAM and a top-shelf CPU, my ability to finish a song grinds to a halt around the 100 track range. My songs can have 150 tracks with 1-20 plugins and 1-30 automation lanes per track by the time they are finished, and the number of hours I’ve lost from crashing or just waiting for it to respond could easily add up to months at this point.
And small things like the inability to know if a plug-in is the VST2 or VST3 version have been driving me nuts for over a decade.
My music is absurdly abnormal in terms of complexity though, and the vast majority of people will never encounter these problems. I worry, however, that the glacial pace of development likely due to the prehistoric tech stack at Ableton will prevent it from ever closing the growing gap made by the increasingly valuable feature sets of modern DAWs have been able to push out quickly and consistently.
Either way, Ableton Live is a great demonstration of the incredibly fine nuance involved in a good UX. They got a lot of little things right, and that alone has been the largest contributor to their success in the industry.
