I'm not sure exactly what you mean by "linking them together". Do you mean having them play on the same audio channel? Or..?

i mean by pressing a key in the keyboard both sounds (vsts) will play as one. if that makes sense.

Shift-click the channels you want to have play when you screw around on the keyboard and they ought to play at the same time. This is how I do it, anyway.
