Do you send the Virus audio to the DAW via alt 3/4 buss?
Leave the stereo line channel at -10dBV and keep the soundcard at +4dBu (The Alt 3/4 buss output is balanced) and then adjust the individual patch volume to suit
Obviously, if you find working another way suits you better, stick to it!!! You can spend alot of time worrying about this stuff......I do
And now Im up to my armpits in balanced multicore and TRS jacks
