Topic: Local Submix creation with FF800

Hello All,
I'm an old user of FF800. However, it looks that I'm missing something and need your help how to resolve the following issue.

I need to route several inputs only to a local submix, and then route this submix output to another submix at specific h/w output. I actually do not need to record this local submix, however I need this routing to be active is stand-alone mode without PC.

How do I do that?

Thanks,
Pavel
