A doubt about the correct way to export "stems"

Hi everyone,

I’m using the word “stem” maybe not in the more correct way but it’s the more synthetic to express what I’ll try to explain here:

I have a project with around fifty tracks, including groups and fx ones; every group includes audio and fx tracks (mainly reverbs), which are routed to the group output itself, and has a couple of insert on it. (i.e. guitars + fx > group; vocals + fx > group; etc.

Theoretically exporting all groups with insert/strip option would give me an exact copy of the final result, apart from master output inserts, is it correct?

Why when I compare all the “stems” playing together with the tracks that generated them I haven’t the same result?

Can it depend on the fact that I had to apply all the inserts are direct offline process as I was using some plugin demo that would end soon?)

Hope I explained my self clearly…

Thanks,

Art
