I am aware of that. But I guess it’s legitimate to ask for a functionality which is offered by another DAW and which is lacking in Nuendo. Same reason why people are asking for VCAs, Playlists (obviously coming in N6.5), and many more. And ViceVersa, PT in between introduced clipgain, native, fastbounce, etc.
So, back to my problem, for now I will try your tip, use 24 WNS-instances, one on every channel - compared to 6 instances in PT still a pity, although Nuendo is different and of course much better in many other tasks.
