So I'm trying to understand why setup 2 would be better. Is the performance in VEP better than in Logic Pro X? Are there other reasons? The only one I can see for certain is that I would get the dry/wet audio from MIR on separate audio returns.
It is less cpu intensive to use VEP
In my setup I have decide to put K5, QLSC, EXS(of course), Omnisphere in Logic and I send the resulted audio to VEP and to MIR
MIR is your concert hall so all instrument should be send to MIR. The problem are instrument like QLSO that does not have a dry signal. You need to find out if an instrument in MIR can be set as DRY !
