"Up is louder", as seasoned audio engineers have put it, back then. ;-D
Assuming that I don't misunderstand your question, you will bring up MIR's wet signal _and_ the MIRacle you've applied to it. It's important to understand that in this quite special case the "dry" signal (from MIRacle's point-of-view) is the wet output from MIR Pro, so make sure not to mute it - unless you're aiming for some kind of special FX.
