Thanks for the advice, definitely useful. The speaker and room setup are fixed, I can't change that at all, so I have to make the best of it. I think I'll start with VBAP since it is easy, and seems lighter than ambi. The sound environment that I am working on now will be made of 6000 sounds moving around, so lightweight is good :)
