No need to use bold fonts! 😉 We hear you.

Please understand that there is no Secret Master Plan To Rule Them All, but just a bunch of audio guys, software engineers and music affcionados who want to cut a swath through the jungle of virtual orchestration. 😉 We're all learning while we're proceeding.
Regarding your question: That's exactly why I added my "PS". 😊 What the screenshot shows is an in-house testing setup which is not meant for use with a release-version of MIR Pro. It shows a recording setup similar, but not identical to Synchron Percussion. But MIR Pro will offer Ambisonics IR recordings, otherwise it won't (it can't!) work as expected. - More details are available in the addendum to MIR Pro's manual, called "Think MIR!".
MIR has eight outputs since its initial release, and while we are indeed discussing the options for even more outputs, the software will stay like it is in this respect for the foreseeable future.
