I’ve gone back to 8.5. Too many blacklisted 32 bit plug ins on 9.
TBH I’m getting pretty fed up with Cubase. Audio drop outs are a continual PITA. Tried all different settings, buffer sizes blah blah. Totally destroys workflow. Even got to the stage where I get the audio drop out box and the mouse pointer disappears! CTRL / ALT / DEL task manager 
Been looking at Reaper. Different animal I know, but Cubase, tell me why I shouldn’t go.
