(Unsolved) Setting up with external interface

[DanBoy]

Hey.. I have only had my virus Ti 2 polar for a few days and i am having a bit of a nightmare setting it up. I have tried reading the manual but nothing indicates what is the best way for me.

I am currently running on Cubase 6, iMac 27'' - M-audio 410 firewire interface with 2 outputs to my yamaha hs80m's. A behringer umx610 & of course my Virus.

I currently have it set up so iMac > Firewire to M-audio > Yamaha Monitors. With my Behringer & my virus plugged in via USB.

With the virus currently i can only have 3 output channels to put insert effects on (USB L&R 1,2 & 3.) But i want more.. Just a couple of questions really

1. Is there a way of achieving more output channels to add insert fx on with the set up i have?

2. Or even if there isn't should i have my set up so its sort of like Anologue Output of virus > Input on soundcard > Imac. To get the best results?

3. Would you recommend me keeping my m-audio as i now have the virus ti which does act as a soundcard i am under the understanding?

Thanks a lot for your time & patience - i have read the manual - watched tutorials for virus & cubase 6 but still cannot make heads or tail of it - thanks!
