I use Melodyne plug-in on Cubase Element 10.5 as a pitch corrector on my vocals. However, after using it, it becomes impossible to mix my vocals.
It’s as if everything becomes fixed in stone and I am not able to change anything anymore. Even panning becomes impossible!
No, it’s not part of Melodyne, it’s in Cubase. Depending on which version of Cubase you have it will be under Edit>Render in Place. If your version doesn’t support Render in Place, then you need to do it manually by soloing the Track, Export the Audio like you would with a mix. Then Import that onto a new Audio Track. Check the manual for details.
