Either there is something wrong with my monitors or the 13 minute Nuendo 6 intro video up on the steinberg home page is only stereo until about the 40 second mark.
You´re in the Cubase forum…
Hey, thanks …
Since I don’t own Nuendo I can’t post it the Nuendo forum. I kinda thought someone at Steinberg might want to know. Nuendo being exactly the kind of software you’d want to use to prevent bad audio with a video 
It’s just the mixer bit that’s mono (only right channel), after that it’s stereo again. But it’s the first thing I noticed too.
Can’t say I’m surprised by this! Just another unchecked bug!
