I’m not sure if it an import issue or some kind of corrupted file, or even a matching issue between iterations, but, on occasion, I’ve had issues with, what I’m calling, “Dead Channels.”
Example: I open an old project that was started in N4 or N6 in N7. Most of the channels play. But I’ll notice a channel that I know has audio on it (I’m looking at the wave file in the project window) and the led meter is dark! I solo the channel and nothing is coming out. It’s dead! I create a new channel next to it and move the event to the newly created channel and it plays just fine. Has anybody else had this experience? What causes something like that?
I’ve had it too. I haven’t had it in a while, and I’m thinking the problem is related to opening anything from a previous version, which seems to happen in Nuendo at times both for older projects and templates.
I have had issues with channels with plug-ins and without. For awhile, it was happening so often and consistently, that I realized that it MUST the template itself. So I wrote a new one from scratch in N7.0 and that seemed to stop the problem.
I am now having a problem with a project that started in N4, was re-developed in N6 then 6.5 and was last worked on in N7.0 as of July 2016. This week end, I tried to open it in N7.1 and it totally crashed Nuendo! I tried launching from the Nuendo document, the backup file and the CSH version. Absolutely no go! I get this same error message every time.
Something is fighting with Eucon, because Nuendo7 just hung up and and Eucon is trying to establish a connection or something that it never achieves. So, I have to stop it from the task manager and re-open Nuendo fro scratch.
I had to go back to the June 2016 version of the project to get it to open. So, I’ve lost the the edits made between June and July. Meanwhile, I have no idea what, why or how the file got corrupted. I would really like to figure THAT out, so as to avoid this occurrence in he future.
