How do I create a bus to control a number of layers as a group?

Say I have a string patch containing a number of layers, how do I bus them together to control the volume of the group with one fader?

Thanks

I usually creat a patch bus, set the output of the respective channel strips to the patch bus and then map volume/whatever to the patch bus channel strip. It’s a literal translation of what you described. How do I create a bus? (I tend to do a patch bus because it’s nit concert-wide). Then how do I control that bus? Map a control to that bus.

For strings layers like you[re talking about, I sometimes create custom expression curves per channel so that foot pedal expression control helps with “articulation” and then still map volume to a screen control assigned to a slider, with min/max volume vale’s on that slider.

It’s a ton of control possibilities. Enjoy.
