  • MIR typical performance on a particular machine

    Hello folks -

    MIR is on sale, which draws me to thoughts of another attempt at buying and using it.  One thing that's difficult about sussing the viability of any solution for one's workflow is being able to ascertain what kind of performance one might expect from it on one's particular system.  There are a lot of posts with statements like "using a modern computer, these settings will most often produce an acceptable result."  I understand that kind of answer - I do!  But it doesn't help too much, really.  So many variables there, including what's acceptable.  We all work differently to a degree - some more real-time than others, for example.  I use a lot of SWAM and SampleModeling instruments, and with my VSL libraries I do a lot of breath-controlled performance, so responsiveness is key.  Being under deadlines, I usually don't want to have to play something dry and then place it in the space after - once the part is in I need to move on, and in any event not hearing things as they will be is a cognitive as well as a working slow-down.

      So in the interest of a narrow but perhaps repeatable spec, I'm asking if anyone else is working with a system like this:  2013 12-Core Mac Pro, 128 GB RAM, Pro Tools (HDX) as sequencer, HD|IO as interface.  Nothing similar to that - that exactly.  A template in VEPro using many different libraries and instruments, not just VSL but Kontakt, SWAM etc. - lots and lots of stuff.  Maybe 40 sources to put into MIR.  And also let's assume that you use HDX plugins for realtime processing as much as possible (as the native round trip on an HDX system causes latency).  What I'm interested in is the following:  If your template requires a 512 or a 1024 buffer in PT, what kind of buffering are you needing to do in VEPro and MIR to get stutter-free playback on a full-orchestra piece, and what latency in live performance does it incur?  Have you found a relationship between raising the VEPRo buffer and being able to lower the MIR one?  and do you get better performance by using MIR in PT or in VEPro?

    I'm thinking that it would be very useful in general if people who used other systems or other platforms also had a place to list configuration and performance specs on this site - is there one? - but I'm really just hoping to hear from people who use the same system I do.

    Thanks!
