I was used, until I upgraded to C12, to edit vocals in a part. Cut & mute, the lowest (bottom of the stack) unmuted edit was sounding ,and everything was a charm to work with. Even with 40 takes and dozens portions.
Now I’m drowning and I didn’t find on the manual why the heck the lowest event is always “blocking” the others, even if it is muted…
This part of Cubase received some drastic changes between version 6 and 12. Once you get used to the new style it should make things easier than before.
Kindly follow raino’s advice regarding a read of the manual. Additionally I am sure there are videos to be found on YouTube that will explain it. Your searchword is “comping”
