Cubase 12.0.51 maintenance update

If you still have Kontakt 5 on your machine it will use it and not replace it automatically with Kontakt 7. If it will be replaced you will get a notification during loading a project.

The replacement occurs only if the plugin is not installed locally and you have a new version able to replace it… that´s all. A notification is then displayed…
