I have done this several times for other mixes for which I am also creating a Dolby Atmos mix and it has worked fine. However, for some reason this session, when I use the wizard to convert it to a Dolby Atmos session, it is not creating the Main Mix channel. After going through the wizard the indicator in the ADM Authoring window is red.
I can then add the output bus manually and then add the Renderer to it. The session says there is a Renderer already in use but there really isn’t one in use. So, it let’s me add it and Cubase adds a send on the Standard Bed, sending to the Renderer and the indicator in ADM Authoring window turns to green.
Again, I have done this many times and it has worked for other sessions. I have also tried this multiples on this one session and each time the wizard doesn’t fully work.
