Thanks so much for the detailed response, Christian. The questions never end
Hope you could withstand a few more questions...
1) To beat the DirectX question into the ground... So running DirectX 9 is possible, just not recommended. I don't think I have the hardware for DirectX 10, nor do I want to pay for a video card that supports it.
2) When you say "MIR is an Application", I wonder if you can clarify for me- Does it run from within Vienna Ensemble? Does it run as a standalone application? If standalone, how does it interface with everything else?
3) It's great that I could run MIR from either my slave or host computer. Which is recommended? Have you found one to be beneficial over the other?
4) It's too bad about the Mac Pro's (Nehalem) design flaw, limiting my RAM usage to 24GB... I believe my older Mac Pro runs DDR2 667MHz RAM. Would I see a huge performance drop if I used the older Mac Pro for VI? And, could I load more instruments with the older Mac Pro (32 GB of DDR2 667 RAM) than I could with the newer one (32 GB of DDR3 1066 RAM), given the design flaw of the Nehalem machine.
5) I hope, at some point, to hear an A/B comparison between a "with MIR" mix and "without MIR". It'd be REALLY cool if you could show us how MIR compares to a more traditional sort of reverb as well, such as Altiverb.
