Nuendo 13 - MIDI playback issue

Hello,

I’ve got Nuendo 12, and I’ve downloaded the trial version of Nuendo 13 (13.0.21), since I didn’t want to upgrade in the middle of a project. I’m on Windows 11.

I’m having a MIDI playback issue from a session created on Nuendo 12 by a client. With the same preferences, the same Kontakt version, the same library, the same Expression Maps, etc., Nuendo 13 does not playback all the notes, and they’re not in time. If I open the same session on Nuendo 12, it works perfectly. If I use the same tracks in a session created (through a template) in Nuendo 13, it works perfectly as well! The issue seems to be between Nuendo 12 and 13.

Did someone experience the same issue? Am I missing something here? I would be so happy to be able to use Nuendo 13’s new features, but I need to be able to work with people who doesn’t necessarily want to upgrade (yet) to Nuendo 13. I never had problems before to open and share sessions between Nuendo 11 and 12, for instance… it’s pretty annoying to encounter this kind of inconvenience, and it’s very frustrating!

I have projects that were started in N12 and continued in N13.
I updated Kontact regularly. I have the Collector’s Edition 13 version. But the latest version of (paid) Kontakt… But never experienced any timing problems or note failures.
If necessary, you can make a backup from your project , delete the track and import it from the backup.
So we have moved at least 30 projects from N12 to N13 without a single problem.
