I see the same problem.  Various libraries in one large instance takes a looooonnnnnggggg time to unload.  It gets to 67% and seems to hang.  It does eventually close.  
Windows 11 here.  

I believe it's the smaller string ensemble sizes toward the bottom of this list (1st Violins-6, 2nd Violins-5, etc).

A little more information on this issue.  First of all I re-installed to the most recent version.  Something got goofed up when I tried to rollback plus I needed to better document what is happening.  

As previously stated if I click on an instance of Kontakt7 (v. 7.13), make an edit to the VST (infinite brass), navigate to the Mixer view, click on another instance of Kontakt7, VEPro hangs and never returns until i forcibly close it.  

However, I did discover that if I save my change to the server project after making each edit this issue didn't occur.  In fact if I open an instance but don't make a change, I can open another instance without issue.  Only if I make a change to a VST does the issue occur.  

In my case all of my Kontakt instances have a single instrument.  Not sure if that's relevant.  

I did roll back to the previous version last night but it was happening with Kontakt 7 plugins specifically.  

My crash happened exactly the way Choison explained.  I click on an instance of Kontakt in a slot from the mixer view, make my edit, go back to mixer view, click on the instance of Kontakt in the second slot to make the same edit and that's when it hangs.  

Since updating I've experienced a lot of hanging.  I'm trying to edit some settings on a VST slot and VEPro becomes unresponsive.  Can't figure out a reason other than I just updated yesterday.  Anyone else experiencing anything similar or are there some known issues?  

Hopefully not.  Been itching to work on my new Dorico template!

Ah ok I see that now.  I guess I assumed those didn't respond to CC1 or CC2 but were merely velocity only for dynamics.  I see now that CC2 is disabled but can be turned on with CC28 right?  

Thank you for pointing me in the right direction.  

I must be doing something wrong, but all of the expression maps that come with Dorico (4.3) are set to use velocity and CC2 for the S'zed SE libs, but when I load those in VEPro CC1 is the VelocityXFade controller.  I guess it's not a huge deal because I can change the CC value in the instance of the player but wondered why this is?  

Steve

Thank you Dietz for the confirmation and the tips.  I'll continue to experiment.  

I'm starting to use a mix of Spitfire and VSL samples and finding my computer can't handle putting an instance of MIR on every channel.  So I'm sending groups of instruments to a BUS which in turn have an FX channel where I position the section as a whole.  

The result is pretty good but wondered if anyone else does anything like this and if there's a better approach?  Not sure it matters but I'm using Studio One as my DAW.  

I understand.  It just seems like that's the only instrument I hear something like that and thought it might be something that needs to be addressed.  But thank you for the explanation.  

Steve

I've noticed at higher velocity XFade values it sounds like 2 flutes instead of a single louder flute.  Is this a known issue or just me?  To be more specific I'm loading the Flute 1 PLUS Velocity and Mod patch.  

Steve

I don't know if this is a DAW problem (though I saw it in Studio One and Reaper) or Vienna Ensemble problem, but I'm working on a template and all the instances of the Synchron player keep reloading.  I'm not even sure what I'm doing to reproduce the behavior but it's pretty annoying.  Anything I can look at? 

Steve

I'm on a quest to not only write the best orchestrated music I can (it all starts there right?) but to render my compositions with fullness and clarity and all the desirable qualities one would like from a well mixed live performance.  I'm struggling with a process for mixing.  I think my first decision is mixing everything in the midi domain vs. bouncing everything to audio.  I do have MIR Pro3D (24) which seems designed to negate the need to bounce to audio but I'm not sure.  

What do others do in this situation?  Advantages or disadvantages?  I'm also making the assumption I don't need to render stems for someone else to mix or master.  

Steve

Ok that makes sense and confirms what i'm seeing.  In the meantime I found another helpful thread on volume/expression and how that affects MIR so i'm doing some testing in that regard as well. 

Thanks again for your help. 

Steve

I think I'm getting the hang of it now.  You pointed me in the right direction so I"m observing things now I hadn't paid attention to before. 

My last question would be should I bother using instrument profiles for the Synchronized-SE library?  If I use an instrument profile it brings the natural volume way down as opposed to Cardoid which I think is the default profile when the various instruments load.  

thanks again for your patience.  

Steve

Well in Studio One I don't have that issue.  Everything is as I would expect. 

So I'm going to do a little more experimenting in Dorico which is where I had the problem. 

.Steve

Thank you Dietz.  I'll do some experimenting later today and report back. 

Steve

I must be doing something wrong because the volume of the instruments (individually and collectively) drops nearly in half when they're in my instance of Mir.  And that's with or without an instrument profile.  Is that normal? 

Steve

Oh ok.  I think I've got it now.  I tried what you said and on the face it sounds like it's going to open up several instances of MIR but both instruments in my test song show up in the same venue.  I think I get it now.  Thank you and again it sounds terrific!!

Thank you Dietz.  I do have a couple questions submitted to Personus support so hopefully specifics regarding Studio One will be addressed.  

I guess one question you might be able to answer is generally speaking can one connect multiple instances of the Synchron Player to MIR 3D(24)?  We can start there and that'll let me know where to look next.  

Steve

I bring this confusion on myself for trying to learn too many new things at once, but in my attempt to learn Studio One (primarily for the ease of sound variations), I am confused how MIR 3D fits into all this.  

First of all it seems sound variations aren't supported with VE so I have to open an instance of synchron player for each instrument.  If this is true, does MIR 3D become a plugin on the Main output channel?  I also want to take the time to learn Dorico and I'm guessing I'll run into the same issue there as well.  

Hope this is the right part of the forum.  I didn't see a 'nitwits' section.  

Steve

Got it.  Thank you.  That was the piece I was missing.
