Cubase 9 is really cool it adds a lot of very useful staff . I think it is the better and more stable daw in the market .
Yeah I updated yesterday, and within an hour I finished installing and was back at my workflow with all my keycommands, presets, eucon shortcuts and plug-ins even my old powercore plug-ins enabled via j-bridge. Until now stable and rock solid. Only problem was VSS3 that I had to reactivate.
For me this is the easiest update ever.
