  • Can my PC handle MIR Pro 24? Need advice from you experts.

    I am thinking of getting MIR Pro but Im not very sure if it is really worth the money since I could probably achieve the same effect with other reverbs with spacial options. Can I even run MIR Pro Smoothly enough or will I notice RAM and latency issues?

  • I have a system that is almost identical to yours, and MIR Pro runs just fine.  Load time is fine, and your amount of RAM should be enough.  I'm running on 16 GB of RAM, and I take full advantage of the "Learn/Enable" feature for unloading unused samples.  MIR Pro is an amazing tool.  I've been using it pretty regularly since I got it.  I also got the second RoomPack for the studios, and those are top notch!  


  • Im thinking of purchasing MIR Pro 24 because I really believe that more than 24 instruments are used rarely if we have ensemble patches. As far as Vienna Ensemble, I dont think I need it since I have cubase mixer, what do you say? Is Vienna Ensemble really worth it?

  • Hi Rolf, Sorry to say that MIR PRO is not like any other reverbs,but I think its better to try first rather than argue. about RAM,yes it will need a lot of RAM,and best of course if you use SSD in RAID my system use 28 Gb RAM and 2Tb SSD Raid 0,and SSD system Drive,and it can handle pretty good specially as you already have X1 machine,it would be better than my self built one Regards, Willy

  • I just tested MIR with a few other orchestral libraries with 16 instruments and it only occupies a little over 2 gigabytes of ram. Not sure why they say it is heavy and all. Do you think MIR 24 is enough? I mean realistically how often will one use more than 24 instruments if we have ensemble patches too?

  • As for what you will need, it will all depend on what you intend to write.  If you are writing for full orchestra, 24 channels can be potentially limiting - though it will work fine with smaller classical sized orchestras.  A Mahler sized orchestra would possibly be a problem...

    While your samples require considerable memory, MIR Pro requires processing power.  Also, you will need to be able to load your samples and MIR 24 on the same machine.  For smaller projects, your computer should be fine.  I can run the older MIR SE (32 channels, but far more limited configurations) and generally do what I need to do on an older i7 930.  JI do have 24 gigs of memory though, and for what I do, 16 gigs would be a serious limitation.

    It is very easy to create a template that requires 12+ gigs of memory, plus however many gigs MIR is requiring, and that will vary depending on the hall used.  Throw in o/s requirements, and the 16 gigs could be used up fairly quickly.  Again, though, you will still be able to do quite a bit with those 16 gigs.  Also, if you have any SSDs, the buffer size can be adjusted down for the VSL samples, and that will lessen memory limitations.

    As for the program itself, MIR is well worth it, and although I continue to use the old version for now, it is one of the most important pieces of software I have.


  • Lets say I only use Solo Strings and Epic Horns for MIR Pro for a string quartet with some horns. Will it use up all my 16 GB or can I work without worries?

  • It's not likely.  The manuals tell you exactly how much RAM you use when you load particular matricies, presets, and patches.  If you are fearful of eating up RAM, use the Learn/Enabled feature for RAM optimization.  That helps so much!


  • Plus, RAM is very inexpensive right now, so if needed, you could just add more.
