Btw, I could give you only general mixing tips, not cubase specific tips, since I never use cubase for mixing, I prefer to export everything and mix in another application. There are people here who use cubase all the time, perhaps someone could give you more detailed pointers. This section of the forum is a bit slow, so you'd have to wait a bit for someone to respond, perhaps a year...
