I'm having a few stability problems with GS3 and Nuendo using ReWire. Would the Giga VST adapter be more suitable?

Also, would it mean that I can export mixdowns without the "real time export" selected (as you can when you use Kontakt as a VSTi)? Doing it for 100 tracks to bring them all into Nuendo as audio is very very time consuming

What does it mean for the DSP outputs? Are they treated as separate or do they come as a single stereo output?

Many thanks!
