How to apply a volume / level change?

Plugins & Modules
1

So I’m trying to do a level change using a plugin (it’s doing more than the level change, the level change is just a part of that). And I’ve tried to reverse engineer the basic VCA, however its not changing the level on my basic plugin set up.

Is there a specific channel that controls level? Which one is it? how should I change that? Addition or multiplication / division?

Any help is incredibly appreciated.

If you are bringing info back in via MIDI then volume would be CC 7.

Is there a way to tell which channel would be volume in general? Like a resource for that?
