I am using Vegas 5.0, with a Delta 1010. I'm mixing 8 channels live to the Delta, input to 8 separate tracks in Vegas. 
How can I setup Vegas so that I can monitor the mix as I record? 
I was thinking that I could route all tracks to a bus, and send the bus to two hardware outputs on my Delta1010. However, no signal is routed from the tracks to the bus at all. 
Am I doing something wrong, or is there some other way to go about this? 
THanks so much!
