After installing the control plugin again I created an Access Music Folder in my VST root where I copied the "Virus TI.vst" and we could get the plugin to work.
So I have 2 Virus TI instances, 1 directly in the VST root and one in the Access Music Folder.
Now we have the problem that everytime I load the plugin from the Access Music Folder (which I have to do to get it working for both of us) the plugin behaves really strange.
There is only some automation available, only the parameters from the VC "Easy" page apparently and only these parameters respond even in writing mode.
Any ideas?
Thanks!
