Sidechaining help! Virus TI2 and Logic 9.1.7

HI

I've searched all around and I simply cannot find the help I need with respect to how to sidechain my Virus TI2 in Logic.

This is what I was doing: (screenshot included to clarify some of my muddy description)

I have an ULTRABEAT in stereo mode as my last Logic channel and this is what I will be sending to BUS1 in hopes of sidechaining. Then I have setup my TI2 as 3 outs/1 input; I have then added it to Logic using the multitimbral option and I have 3 Virus channels- 1 main and 2 aux. I set the TI2 so that each of the Virus channels is USB1+2, USB3+4 and USB5+6; meaning that each channel is stereo.

Now each channel (the ULTRABEAT and the 3 TI2 channels) has a compressor, space designer and adlimiter and they all work fine. On one of the channels of the TI2 (for argument's sake we'll use USB5+6 which is the last Virus channel but the third Logic channel as you'll recall my ULTRABEAT is stereo and the last Logic channel) I add a compressor at the TOP of the channel strip (above the compressor I already am using for that channel) this is the compressor I hope to use to pickup the ULTRABEAT send to BUS1 and sidechain the beat with a bass synth from the VIRUS.

This is where things go wrong. Using this method I have yet to be able to get synced proper playback; however if I use the TI2 as a stereo/1 channel logic instrument the sidechaining like this works fine- except I cannot use more than one channel from the Virus at a time which defeats the purpose of the Virus. I note that I do not know much about sidenchaining and that I am using a method I researched online. I also see that (like most windows in Logic) there is a little sidechain box on the Virus TI window- should I have been using it instead of this compressor method? I need some babystep pointers and assistance please! Sidechaining is very necessary for me and I need to figure it out.

Thanks in advance for all your time and careful consideration!

FOR F*CK SAKES: I can't attach my screenshot because my message is too long? REALLY?

Hi Flabber!

yes I can verify that the 3 channel of the virus is USB 5+6 and this is the channel with the extra compression at the top to pickup the ULTRABEAT bus 1 send also if I turn the compressor off (bypass) or turn the sidechain bus 1 option to none the Virus bass sound plays once again in sync.

Thanks for your help! Sorry it took me a bit to get back to you I needed to restore a backup of my 10.7.4 system so I could get back to work as 10.8 doesn't work with my TI2 with release version 4.5.3; too, my Virus doesn't like the OS5 public beta and plays out-of-sync and is unusable so I had to downgrade.
