Project skipping in it's buffer wildly when many Vocalign regions are rendered.

I find it best practice to render region effects as I go so as to keep the engine purring along.
Yesterday I Vocaligned a horribly out of sync performance from an "internet singer" phrase by phrase rendering as I went. When it was done I started play from the top and SONAR kept stumbling and glitching as if something was really interrupting it. I wondered what it could be then a saw the string of rfx clips from my Vocalign edits. So, figuring it couldn't hurt, bounced the track to clips. - That fixed it.
 
This is different than any other rfx I have used where rendering was enough.
And maybe nobody will use Vocalign. Seems pretty quiet around here on the subject.

    I was encountering the skipping problem too while the VocALign instances were live, but rendering them seemed to fix the problem.  Is it possible that you missed rendering one that the bounce operation caught?
     
    It's weird that it's having this skipping behavior at all, though, since the CPU usage doesn't seem to go up much when the VocALign instances are added.  It seems like some kind of bug.  I've always been able to use many instances of Melodyne without having to render any of them.

    After some more experimentation, it appears that VocALign is generating short but intense CPU spikes from time to time that are causing the dropouts.  However, if "Plugin Load Balancing" is enabled you don't see the spikes showing SONAR's CPU meters, yet they are still causing the dropouts.

    I suppose I could have missed one yeah. Too late to tell now though.

    Yeah, the reason I was wondering is I noticed that if I have an VocAlign clip anywhere in the project, it causes the audio dropouts everywhere in the project, even if there are no VocAlign clips playing in those areas.  So, even if you had missed rendering one small clip in the middle somewhere, you'd be getting the dropouts everywhere.  Hopefully it's something that will get fixed in the future.

    Can confirm I'm seeing odd behavior as well. I get a high pitched 'motorboat' randomly when listening through the plugin. High buffers don't seem to help, neither does closing the Vocalign GUI. FWIW I'm on a Ryzen 1800x/MOTU ultralite Mk4.

    This discussion has been very helpful to me, having bought VocAlign yesterday I thought it was unusable due to the excessive audio dropouts after using it, however after reading this thread I realize that you have to render each track
    and double check that you have nothing left unrendered in the project. 
     
    Thanks
