X-cross between two automation


Is there a way to make two automation line be zero-sum?
For example, I’m raising send(to fx) level of a track, and at the same time decreasing
vomlume of this track. And I wonder if there is a way to do this automatically.
Like, when I raise the send level manually, the volume automation decrease
automatically and correspondingly.

Thanks for somebody who helps!


Unfortunately, there is no such a function.
