Hello Neil!
I wish you a Happy New Year and whatever else you hope for in 2014 
As always I support your opinion about a proper support of surround formats and
as usual we won’t even get an answer from SB. 
Btw, I have just bought a Harrison MixBus in the Don’t Crack group buy (-75%).
What I see from the videos, it comes much closer to what I want to have in a DAW.
It is not yet fully developed as to Midi or VSTi, but I kinda like the “analog” workflow.
I mean, for 200 $ incl. FX-bundles … makes my old console heart swing.
I can’t still get myself to work on N6. Well, for some reason I was forced to do a small project on it, but after that I was strongly tempted to kill it from the Studio-PC, completely. I still hate it as much as I like N5.
Cheers, Big K
