Have 2 machines - one is a testing machine for updates so the main system can stay predictably stable on 8.5.
After installing 9.0.2 on the testing machine it was a buggy mess - crashes all over the place - and I mean hard crashes, where prefs, window layouts, etc. all got corrupted. The usual Cubase “when it crashes the whole software inexplicably gets trashed” kind of crash.
Reinstalled Windows 10, only installed 9.0.2…instead of having 8.5 on it as well. It is now smooth and bug free.
I would recommend with Cubase 9 to do a totally OS clean install. Definitely a PITA, but seriously it got rid of every single problem I was having. Except another post I made about having problems 2 key commands (read / write), otherwise tip top shape.
NOTE: Still would love to know why, when Cubase does crash, it sometimes takes every user setting down with it: preferences, windows layouts, plugin layouts, etc. This software is absolutely terrible at retaining user settings. Can’t count the number of times I’ve had to trash preferences, recopy windows / plugin / mediabay databases, re setup the transport part / track settings / mixer toolbar, etc. Even when you save presets they occasionally get deleted after a big crash. Mind boggling. There’s seriously something amiss in the core workings of the software…I have never used a software that crashes as hard as Cubase does, and does so much damage to user settings. Perhaps if the engineers took a serious look at the disaster zone that is the XML file locations…spread all over the C drive willy nilly…it might help us backup and restore these ridiculous crashes. /endrant
