There are three ways MIR Pro can be run:

1. as a VST
2. inside VE-regular
3. inside VE Pro

Thank you. So effectively, as a VST, I need a separate MIR PRO instance per instrument. Which will eat up a ton of my CPU cycles... 😕 Am I right?

I haven't paid attention to the CPU effects, but I doubt you're right about that, because when you run it as a VST, each MIR VST you add isn't totally separate. There's a single MIR room, which I think VSL has called the "engine", and each track where you add a VST gets a little thing added, but it's just for communicating with the single MIR room. In the end, I doubt using MIR as a VST takes any more CPU than using it in VE.

The Plug-In (VST) manual descibes it: "the plug-in version of MIR Pro relies on two different parts, namely the actual plug-in, and a common control user interface (UI) shared by all instantiated plug-ins."

Looking in my Win Task Manager, I see just one Win 8.1 process for the MIR engine, while I'm using multiple instruments in VST MIR.

To use a room pack, I need VE??

You don't need VE to use the room packs.

"Venue Presets are the ideal starting points for your mixes in Vienna MIR PRO / MIR PRO 24, but they will also inspire you to use recording setups of your virtual instruments and ensembles that you may not have considered previously. Each Venue Preset is built around one Main Microphone position within a chosen Vienna MIR PRO / MIR PRO 24 venue and has been specifically created for a dedicated task with individual output formats, fine-tuned main microphone and secondary microphone positions, optimized room EQ settings as well as suggested RoomTone levels. Although some Venue Presets are set up as 5.0 and 5.1 surround configurations, great care has been taken to achieve perfect stereo balance and all-embracing stereo width."

Using the Venue Presets does require a license for VE Pro, and it requires you to insert VE Pro in your workflow. Without VE Pro, you still can use the three MIRx presets, or you can still set up everything manually. 

What about the reverb options available with the Vienna Suite?  For half the price of the MIR you get some really nice verbs (algorithm verbs with the Hybrid in addition to a pretty sweet convolution reverb package) along with some other nice plug ins e.g. EQ's, Compressor, Multiband Limiter, etc.  All, of course, have some very useful presets that you can use out of the box or as good starting points.

MIR might be overkill for you--it depends on your needs--in which case the Vienna Suite is just sweet. 

Vienna Suite also has a free demo license to give it a spin.

I love VEPro and MIR Pro (VSL you can put a 100 euro in my account :) )

Getting serious my life as change since I use MIR PRO and VE PRO.

Lol Cyril I know what you mean, MIR sort of like the first time I used a true legato library, but the placement equivalent.  It just felt like "this is the next big thing."

Once they sober up from their dimension-basses celebration it would be nice if they could make this not happen anymore.
