If you understand VCAs in Pro Tools you’ll peobably know that unlike the meter of an Aux Track being used for submixing, a VCA shows the highest level reached by any member of the group to which it is assigned. it doesn’t the sum of the levels of the members of the group because a VCA doesn’t sum signals. Instead it shows the highest peak level reached by any member of its group.

But do you know what kind of meter you’ll see this on in terms of meter width? if you combine a 5.1 track and some mono tracks do you see a 5.1 meter or a mono meter on the VCA? Find out how it works in our quiz.

Can you see the rule which is at work here?
