To be honest, it can't add gain.
A volume envelope is what it is, and all they can do is 'reduce'from the top level. It can't make things louder, but it will allow drawing in relative curves.

So you may still need the gain change to make the max volume 'loud enough', then the volume envelopes adjust it from there.


I do not work here, but the benefits are still awesome
