I might be able to help - I'm using a TI. What Virus do you have?
Basically, I run my MIC into the virus and have set up a "patch" just for my vocals - so I don't need to keep adjusting the Virus every time I lay down Vox. I just boost the signal in the EQ (the gain - in the Lo, Mid and Hi) in the FX section and it comes out through the DAW when it's set to External in.
There might be a better way that someone here might know, but it's worked out pretty well for me so far.
