Hi… No, certainly on my rig (N7.0.20, Mac Pro running Yosemite, two Artist Mix and one Artist Control) track hiding in the N7 mixer does not hide the corresponding track on the Avid/Euphonix control surfaces.
I had hoped (and was under the impression) that this would start happening with N7 and the latest Eucon, etc. I believe it was promised to arrive with Eucon 3, as it was apparently the limitations of Eucon 2 that stopped Steinberg from implementing it.
But nope, no joy here. FWIW, I don’t think the Artist series has been able to do this with any previous version of Nuendo either.
I’m like you, I end up with fairly large track counts. I frequently need to do automation passes on a set of tracks that are scattered across the mixer, and the obvious way to do that is to hide all the tracks in-between the tracks in question so that the channels you need are side-by-side on the faders. But that’s a no-go.
My current solutions (in no particular order of preference) are, or have been:
Just do multiple passes. Boring.
Move the tracks I want to automate to the end of the track list. This totally fouls up my channel order, but when I’m in a rush and I know that this automation pass is the last thing I’m going to do to the project before never looking at it again, it’s an option.
Something I’ve recently started doing - Make a new VCA fader for each channel that I need to automate, then keep all the VCA faders together at the bottom of the track list and automate those faders instead. Obviously this has only become an option since N7. It works ok, but means I’m adding a lot of unnecessary tracks. Also, I guess this solution is only any good for automating channel faders i.e. not pans, sends, fx, etc.
If anyone knows more about the status of this feature, mark me down as very interested. Maybe I’ve missed something? An option in the Eucon prefs maybe, or…?
