I think the problem is much deeper with a general problem with “linking” being just too rudimentary and not sufficiently thought through. In PT I use groups all the time - when automating manually or editing it, when editing in the edit window, when setting routing etc - and without it done right in Nuendo I just lose time, every single time I work in it. I cringe every time I see add-ons released by Steinberg since those resources would be much better used bringing the basic application - the foundation of the work we do - into this decade as far as some basic functionality is concerned.
By the way David, I saw Chaka two weeks ago. It was… interesting… I envy you!
