The update is amazing! Totally amazing. It fixed loads of my bugbears. Faster loading of VST it seems (NI Stuff). And also my major annoyance was when you hit record on a midi clip for a synth on 9.5 it wouldn't work to a fixed length, even though fixed length was set. That seems to have been fixed. Which has made me happy no end.
So a big thanks Ableton. You're my new heroes for the day!
