thanks crossfire,
ok ive re-watched the ableton live tutorial video and that made a bit more sense this time round.
it says using the "utility" plugin is the key to splitting the virus parts.
for the mono outs like "USB 1 L" or "USB 1 R" does this mean u can only have these parts in Mono?
i still dont really understand how to go about this tho....

can anybody elaborate plz?
also my USB 3 outs are not selectable...(i can see them but cant click on them) but in the ableton input channel chooser i can only see "2-Virus TI" & "3-Virus TI" but no "1-Virus TI" ...any idea why?
