Funny, I'm interested in this exact same question. I sort of snuck it into a non-dedicated thread, in post #5 of
this thread, but I knew it might not get a lot of attention there, so I'm glad you created a new thread for the discussion.
To elaborate a bit, I think we're both talking about using two instances of Virus Control at once. In my case I guess you could say I'm only interested in "Partial Integration" since I completely gave up on trying to use the audio streaming over USB feature, I've got the outs going straight into the interface via 3/4" cable, and the USB pipeline is strictly for MIDI communication between the Snow and the plugin.
