Hi Simon.

1.Do you mean the Cubase process stays open in this case, not the BB process?
Yes.
2. Do these problems happen on a fresh boot, having not run any of your other audio apps or used the Fireface at all?
Yes.
3. As for Cubase I just mention it happens ALSO with Cubase.
Cubase didn't run while running BB (Restart - run Cubase, restart - run BB.
