Virus Inputs - am I thinking about this correctly

[Doc Jones]

What i want to do - route my Roland Jv-2080's analog audio output directly into the TIs analog inputs to manipulate the audio and then transfer the audio through the usb cable and into cubase.

First of all, can this even be done?

Here is the setup - I have a Korg Kontrol 49 keyboard for midi input into cubase and midi is sent to the 2080 via the echo layla midi out.

I read the manual, hooked up my roland jv-2080 stereo outs to the L+R analog ins on my virus TI. Under the main config menu for the synth, I set Input Thru to 127,Source =analog and characteristic =linear. I launched the VC, on the ti I selected an empty part - went to edit - inputs page - and set the mode to dynamic and the input select to L+R.
In cubase I create a midi track, the Kontrol49 as the midi in and the Layla midi as the midi out (to the jv-2080). I plugged headphones into the TI and play the 2080 = can hear the 2080.

The problem, even though I hear the 2080 via the TI headphone jack, I can't seem to be able to use the TIs filters or effects on the 2080 sound and can't seem to get the 2080 sound into cubase through the usb.

Any ideas?
