Hi McArnes,
Thanks again for our interest in MIR Pro. I answered your questions already on VI Control, but for the sake of completeness I'll copy/paste my replies:
Quote:I'm demo testing Mir Pro 24 and a couple of the Room packs now, but I'm a little confused.
1. Does Mir Pro 24 come with any of the Room packs or is it completely without any rooms?
MIR Pro is the engine, the "sample player", if you want. The RoomPacks contain the IRs of your choice.
Quote:2. Do you know how much CPU and RAM one instance of Mir Pro 24 use?
This depends on a lot of factors, like the actual reverb length, cache and buffer settings, but also on system-related ones like processor architecture, RAM speed etc.. As a rule of thumb, CPU speed is always crucial for MIR Pro, RAM size is much more usage dependent.
Quote:3. Does Miracle come with Mir Pro 24? I didn't realize I had a Miracle demo also until it suddenly appeared in my Audio FX list in Logic. Is Miracle a simple version of Mir Pro 24, or an algorithmic reverb based on Mir Pro 24?
Like mentioned in the manual, MIRacle is an algorithmic reverb add-on for those who don't have access to a Lexicon 480 ;-) for spicing up the natural (and sometimes quite raw) sounding room information derived from MIR. It's an integral part of the license.
Quote:4. Is it possible to have early reflections "bleed" from one instance with the woodwinds to one instance with the brass, or is there some automatic thing going on between the instances, as the placement of instruments changes the room and how the sound is developed. This is why some like to bleed early reflections by sending this between buses.
This "bleed" concept comes from conventional reverberation approaches, I guess. :-) MIR's impulse responses are all recorded in the same room, using the same mic positions, but different IR positions and directions, and much of the interaction that would happen between instruments in this room (due to phase cancellations and the like) will happen in MIR Pro, too. But of course there is no "bleed" from one instrument in another instrument's channel.
Quote:5. Does it work well for placing whole instrument sections, or does it have to be each instrument (I know you can, but wondering if 20 violins in one instance or 12 horns in one instance sounds OK or weird).
The more individual signals you give MIR to work with, the better (due to reasons mentioned above). MIR relies on highly sophisticated "Instrument Profiles" to make sure that the typical sound emanation patterns of each instrument type are emulated. - But technically it's ok to use ensemble submixes, too.
Quote:The reason I ask is that my system would not handle each instrument in the orchestra + various solo instruments/non-orchestral. So my plan is groups:
[...]
Which I hope my system can handle.
That's nothing that would make a modern DAW sweat, especially with higher latency settings.
Quote:6. Is having two different instances for choir necessary or can I just use the width slider for it to reach the left and right side of the choir? Is more than one instance for each desk for the strings necessary? I thought of it as a compromise for not having every instrument in Mir Pro 24.
MIR will handle stereo signals with ease, of course, and as a matter of fact it takes care for proper distance-dependent handling of stereo width all by itself, as the engine is completely based on Ambisonics. But you can overrule this natural narrowing manually, of course. - Using individual instances for each desk is good practice (e.g. with VSL's Dimension Instruments series), but truth to be told: You will get quite far with a submix sent into one single instance of MIR Pro, too.
Quote:7. Is it recommended to use Mir Pro on a slave computer inside VEP6? Or on the master machine inside the daw?
That depends completely on your needs and habits. Personally I like to have MIR on my main mixing system, though, and this makes sense especially when taking into account that MIR's license is valid for one machine only. - Keep in mind that MIR Pro comes as "ordinary" VST/AU/AAX plug-in too. It does not necessarily need VE Pro as host (although its workflow is much more streamlined there, especially when using Vienna Instruments).
Quote:8. If on the slave, can I still use Miracle in the DAW on my master machine?
No. MIRacle needs to see the same eLicenser as MIR Pro itself.
Quote:9. Is there an overview of the dimensions of the various halls in each Roompack?
Yes, of course. Either in the RoomPack manuals, on
VSL's product websites, or during the Venue selection in MIR Pro's GUI.
Quote:10. Must Mir Pro be added as a plugin on each instrument/mixer channel, or can I have one instance of Mir Pro on its own bus, and send the instruments to it?
Like mentioned before: MIR should be used on individual sound sources, but technically you can use submixes, too. - MIR Pro is _not_ meant to be used as conventional AUX-send based reverb, though, as it has to take care for the positioning of the dry/direct signal components too, to work as expected.
