The following request I sent to the yamahaproaudiosupport. When I get a response I would get back to you again.
Unfortunately, the studio manager does not work in Cubase 8. Close the window in the new Cubase leading to a crash of Cubase. If the window is opened, there is an error message when you quit Cubase. I work with Mac OS (Mavericks) and Cubase is running in 32-bit mode. Therefore 2 questions. Is the problem known and will be fixed? Will there be in the future a 64-bit version of Studio Manager for Mac OS? Yamaha builds equipment that will last a life - logically, the user will then work a life with it and take advantage of new software. The Studio Manager problem affects many users as I could already read in various forums.
