Go here: Celemony | What can Melodyne do? and check out the A Capella video at around 4:50 and you will see wave graphics moving upwards in the channel mixer. Huh???
I canāt find the video you mention, but I believe that is a Nuendo feature.
You have to click on ātutorialsā to find the A Capella video. Nuendoā¦that is probably it.
Found it.
Also found this.
Nuendo only.
