We haven’t done any serious investigation into the specifics of how to integrate any of Dorico into Cubase, though this is definitely the long-term goal. I wouldn’t like to speculate as to how hard or otherwise it might be to achieve this in comparison to integrating the audio engine with Dorico, but there is so much functionality in Cubase’s score editor, and it is so tightly integrated with all of the other MIDI editing features in the application, that I’m pretty sure it won’t be at all easy. We would want to allow Cubase to have the beautiful graphical results that Dorico produces, but retaining all of the familiar and consistent workflows that Cubase users are used to when switching between its various editors.
