I have done a 10.9. installation on a fresh drive but same Mac Pro. (The one I have the crashes with a 10.8. N6 installation.)
Nothing installed now but: 10.9., Nuendo 6.07, last Fireface drivers, last Eucon drivers…and yes: Nuendo 6.0.7 crashes as soon as a track is routed to a 5.1 output
What I found out (just to be a bit more precise). The crash will happen as soon as this mono track (routed to a 5.1 output) will be assigned to a Artist Control fader (as part of a bank).
There should help be coming from N 6.5. but as that will take some more time I started testing again. What in such a basic installation can make the difference that some system have the crashes, some not. Processor type??? Memory?? Video card?? Audio Interface??
