While MIRacle is based on a similar technical approach, it is not meant to actually _replace_ Vienna Suite's Hybrid Reverb. Much of HR's sound comes from the IRs used for the early reflection part. The same is true for MIRacle, of course, but due to the fact that the IRs are very different, the results will be, too.
You can send both the dry and the wet signals (derived from IRs) to the algorithmic reverb processor for that "hybrid" reverb approach. In fact, many presets of HR work this way, too. What I was trying to point out in the examples given in MIR Pro manual's Tutorial Section is that there's more than one way to skin a cat. ;-) ... With MIR Pro's plug-in version it is not easily possible to route the wet signal parts of MIR Pro to other destinations than the direct signal, though. You would need VE Pro as a host for MIR Pro to achieve that without quite involved work-arounds.*)
*) Sidenote: That's not us beeing greedy, but simply a restriction of all popular plug-in standards. ;-)
