OK, this is what I did. I'm going to try a few different methods but a brainstorm got this working for me, so don't tell me I'm making something simple complicated because I just got this working haha:

#1. I created a "group channel track" (project>add track>group channel)
#2. in configuration, make that a "quadro" group (this is the old method of creating a sidechain in cubase sx3)
#3. in that group channel track, click on the little "e" and in "inserts" add Virus TI /// (the VST3 effect version I guess)
------this will make the TI load up, but in mine I always got a blank plug graphic and didn't know what to do
#4. make sure you enable the sidechain button
#5. on the TI unit itself, navigate to the patch eROM-A 125 >>INPUT<<
#6. now hit F3 to go to the mixer. with whatever audio tracks you want to run through the TI, change "Stereo Out" to "Sidechains - Group 1: Ins 1 - Virus TI"
#7. HOORAY, play with the TI's effects to your heart's delight!!!!! (remember to use the TI itself to screw around with effects)
