Hauptwerk and Vienna Symphonic Library

I'm in process to design a new Hauptwerk Organ with 4 manuals and plan to integrate also some of the Vienna Symphonic Libraries (VSL) that comes with a separate instrument player software. Wondering if somebody has tried to integrate VSL with Hauptwerk. As I think now, I probably going to need a separate computer for the VSL and then assign one manual that is also velocity sensitive to it.

Does anybody have some experience with the combination of Hauptwerk and VSL? Any experience, comment or recommendations are welcome.

I also created a website for the new project: https://hauptwerktampa.com

The new organ will be installed in a music school.
