It is hard to research exactly what I am trying to find out.

I have BIAB 2016, and have not looked at any upgrade until now.

I do jazz arrangements--mostly guitar (me), a vocalist (live), and from Real Tracks, I would have bass and drums and sometimes a piano, etc. Nothing complicated. I have made demo recordings with Real Tracks pretty much since it came out, and they have sounded pretty good.

For this limited use (me recording guitar and maybe vocal tracks to jazz standards), is there much benefit in upgrading from 2016?
