Routing External Audio Through Virus TI

[synthfiend]

is it possible to run an external audio source into the analogue INs on the virus and have the virus just mix this external source with its own sound....

example being, running the analogue outs from your PCs sound card into the virus, whilst just playing the virus like a traditional synth. The sound out of the analogue outs on the virus would then be a mix of your PC and the virus itself.
