The update to C8 from C7.5 went very smoothly. I worked on a project created in 7.5 with no problems with backward compatibility.
However so far 2 things:
The control devices for Frontier Tranzport and Alphatrack no longer appear in the list of devices.
During a Render in Place, after 3 successful renders, the fourth one hung Cubase. I had to kill off the process and start over. I was using rendering by blocks. Once I reloaded and rendered the same track using the One Event option, it went fine. The only plugin on the track was Melodyne.
Is there some incompatibility with the Frontier Tranzport? I use that a lot so it would be nice to get that back.
