I will tell you that NOTHING gets done with the signal coming in on the sidechain inputs, except for calculating its level to present to the detector of the sidechain. There is ZERO way it goes to the outputs of the plugin. It’s simply not possible. The plugin does not do this on REAPER, or Logic, or any other host that I can think of, and the way the plugin works does not change depending on the host (unless it’s to simply turn off sidechain altogether because the host doesn’t support it…SAW comes to mind)
Maybe somebody else can offer some suggestions, or maybe someone on the Cubase forums can answer your Cubase-specific question. I will try to get a copy to download, but that’s only a temporary solution to YOUR problem, and doesn’t help any other users after that download copy times out. I don’t expect to see anything to fix your problem, because I don’t think there IS a problem. You need to make sure that the 3rd and 4th inputs to the quadro buss are not being routed to the outputs, is all I can think of.
I understand that you have a problem, and I’m sorry, I just don’t think it is a problem with my plugin. The Rocket is used with sidechain by tons of people on tons of hosts…if bleed-through was a problem, EVERYONE would be complaining by now…including me, because I use it constantly.
I promise I will download and test, though, just to be complete.
