This is what I’ve wished cubase would do. Integrate Dorico scoring software and Cubase to keep project synchronisation
It looks like they’ve created a way for Notion and Studio One to send data via a local network protocol they have created, and you can invoke a command to send the data from one to the other. In reading about it I don’t see that edits made in one program are reflected in the other, which is what I would understand from the word ‘integrate’. E.g., “The Cubase Score Editor is integrated into Cubase.”
