Easy as apple pie:
You look up in the midi controller list(in the virus manual, damn i'm evil to ya) and find out the number of the controller you want do automate in SX.
Then you go to SX and in the midi editor(the one with the piano roll) you just go to the bottom and choose the number of the controller...there might stand something like "breath" or something instead of the number but you can count what number it is from the other numbers.
Understandable?
I dont blame ya if you dont
