Thanks for the screen shot. Nearly all legato notes -- only one repetition. 

Hey Dewdman, an interesting behavior here: copy the matrix that we're working on ( unnamed, D6 ), create a new instance, paste that matrix into the new instance. It works.

I hope you witness the same. It argues for either A. a corrupted preset or B. some kind of instance setting that a new, default instance does not have.  To be honest, that whole original preset seems finicky to me. 

But when it works in the new instance, wow -- twelve horns sound pretty good.

Berlioz' Requiem. 😃

I tried copying the matrix, didn't change anything for me...notes still getting dropped.

Hmm. Did you create a fresh instance, create a VI channel in the fresh instance, and then paste the copied matrix into the new channel? Here the difference was night and day.

Yep, I get the same thing here.  But why?  

I threw another fifteen minutes at this. I reduced the offending matrix down to the one cell in question and saved the instance / project. It appears whenever that's reloaded, the bug continues. It's only when the matrix is separately copied and then pasted to a new instance that it's fixed.

I've also observed that the broken instance / project is still broken if you load it into Vienna Instruments Standalone.

I've scoured the instance for a unique setting to affect its playback, and I can't find anything to differentiate it from any other instance. And dragging fresh, identical patches into the slots does nothing. 

I also copy and pasted a customized Flute channel of my own into the bad instance, and immediately it acted up -- there was the same interrupted or unperforming notes. 

I know "a corrupted file" can be a very unsatisfying answer. But I'm out of ideas. 

another interesting test would be to try out the original VePro frame made by Jay. Attached. I will check that out right now too.

problem seems to exist in the original viframe file provided by Jay also.  So...  nothing I did in saving the preset caused it.  Its encoded into the viframe in some way for ViPro settings.  However, that was made years ago and undoubtedly viFrame files have changed since then...so who knows...  I'm going to call this a "bug" related to opening old viframe's in newer ViPro or VePro...not sure which or why....

Actually though, even after doing the copy matrix and paste to a clean ViPro preset...  The midi that was originally recorded by Jay still does not play correctly.  So doing this copy/paste matrix clearly results in a different preset in some way and does respond better, but it still must not be the original ViPro preset that Jay used, because it still doesn't play the phrase right.

I made some more progress on testing today.

First, I am running into two seperate issues, which may or may not be related.

1. Fast repeated notes are not working right with presets that were saved in a viframe from 2014 by Jay Bacal. We can't figure out why. I am attaching to this post that preset, along with a new preset where I built it up from scratch using the same underlying patch (HO-8_perf_legato) (in mono legato mode). The version I build from scratch handles fast repeats fine, the one that came from Jay Bacal's viframe of the ET score tutorial, does not. I can't see any difference etween the two presets in the GUI, but obviously something under the covers is different.
   
   
2. Midi phrase playback of at least one phrase in particular is not happening correctly, from LogicPro. This happens with or without VePro. I am attaching to this post a small LogicPro project that has just two tracks, one with the Horn part and one with nothing on it. When the Horn track is selected (in live mode), the phrase plays back exactly as expected. When the other track is selected (before hitting PLAY), the Horn track is no longer in live mode...and ViPro starts dropping notes all over the place. This happens both with and without VePro, so the problem must be ViPro and/or something about LogicPro live mode. I also get this problem even if I create a new preset from scratch as mentioned above, the problem persists either way.
   
   

I think those are most likely two seperate issues. I can't seem to get the phrase note dropping (issue #2) to happen in Cubase so far. But I might not konw what I'm doing in Cubase to avoid live mode. I do get the note repetition problem (issue #1) in both Cubase and LogicPro, regardless of whether VePro is being used.

If anyone has any other thoughts about these, especially issue#2 above, please advise.

To solve the initial problem you described, try turning Optimize off in VI Pro.  Optimize keeps the used samples in RAM, all other samples will be discarded.  Due to some slight difference in sequencer or system it's possible that what was an unused sample when Jay saved the file is a used sample on your system.

I had a similar problem of a few notes not sounding when playing one of Jay's other tutorials.  Turning off Optimize and resaving the project solved this for me.  Good luck.

I tried turning off Optimize and resaving the preset.  

This did appear to resolve issue#1 above, the repetition notes.  It did not solve issue#2.

I wonder about this optimize feature exactly why that have caused that problem?  When I loaded the preset initially, all cells were enabled.  But it seems like somehow some internal stuff was not loaded into ram with optimize enabled...and playing notes doesn't seem to load them either.  Can anyone comment more about that optimize feature, what its supposed to do and why it would cause that?

I can also say, even after trying to turn off optimize, I am finding some notes have a note dropping problem, intermittently, while trying to play legato.  With this preset, I find the top few notes of the keyrange for the instrument exhibit this problem 30% of the time while playing legato transitions manually on the keyboard.  The second played note cuts off the first (as expected), but makes no sound itself.  But it doesn't do this all the time, just intermittantly.  

Also.  It appears that none of these problerms are happening when I use ViPro inside Cubase.  Somehow this is related to LogicPro.
