[Sorta Solved] Single discontinuity "glitch" in exported stereo audio now.

SPlat (Happened with same file in X3).
 
I export this pedestrian country tune of oh, 30 or so tracks and drum, tts-1, mda sound font synth and audio to a stereo 44.1khz file and there of late has been one discontinuity in the export each time I export. Always at a different spot in the tune each time, every time I export. The cwp file plays great - all the time though.
 
The glitch is 0 level audio for a small bit of unknown samples that sounds like a clean cd skip.
I have my network cards disabled, no av, or infections, and I just replaced the data drive doing an offline drag n' drop copy (inherent defrag) to it hoping the drive I had being long in the tooth and fragmentation was the culprit.
 
My DPC latency is stellar.
 
Quad Xeon Dell Precision 690 / windows 7 32 bit
Splat Lexington.
Terratec EWS88D
 
I ran a commercial studio for years on this setup without issue.
Now I can't export this song.
And I think it's only this song but it's the one I'm working on now.
 
I'm out of things to try. Anybody else experience / and fix such a thing?
 
:Ron

    Myself I would first try exporting with certain suspect tracks not selected. 
    This sounds lik a VST issue to me. I'd be looking for the offending synth or effect. 
    You set up seems way out of date so you might just be running on borrowed time too. 
    I'm not sure if the new Sonar is all the stable in 32 bit world anymore as example. 
    Is there a reason your not using W7 64 bit?? 
     
    Edit added later: 
    OK I looked up your interface 1998? - 2002  I guess 64 bit drivers would be an issue. I think it's time for a new one.

    Hi Bit,
    I run into stuff like this every now and then as well. I usually try the following:
    1. Disable fast bounce
    2. Live playback to a new track using a loop
    3. start going through my VSTi's and FX to see which once is causing me a problem.
     
    TBH, if live playback works and you can set up a loop (or handy dandy new Aux track) to record to a new track that might be your best option if you're under time pressure and don't want to mess with disabling plugins.

    I once had something like this, and as the others have suggested, it was a VST that didn't like Fast Bounce. Try freezing any VSTis and seeing if that helps.

    Sonar Platinum (Newburyport) / Win 8.1 64bit / Focusrite Scarlett 6i6 / Absynth / Kontakt / Play / Superior Drummer 2 / ESP LTD guitar / etc

    Thanks guys.
     
    I'm stuck @work but will bear down and try to find the issue using these suggestions tonight and tomorrow.

    I got home, fired up the daw and unchecked fast-bounce, exporting in real time, not audible.
    The resulting export was glitch free for the first time in I forget when.
     
    Now comes the task of finding out which vst or vsti doesn't like fast-bounce. What fun this shall be.
    Golly Gee, I hope it's not one I like.
     
    At least tomorrow is Saturday.

    Well boys and girls it seems to be the UAD-1 EMT 140 on the master bus.
     
    Surprise surprise I guess.

    Glad you got it figured, but that's gotta be aggravating. Just out of curiosity, is it an old UAD-1 version? Just wondering if the UAD-1 was a typo and you really meant UAD-2. I like my UAD stuff a ton, but as finicky as they are sometimes, there are days when I wonder if they're worth the heartburn. I'm guessing if it was on your 2-bus there were other plugs in the same fx bin, maybe it was a combination of plugs that was causing the problem? Some kind of 32 bit combined with 64 thing maybe?
     
    Not a big deal...really just wondering if there's anything I should avoid.
     
    Thanks for updating with your findings.

    Dean, it's all 32 bit and is indeed UAD-ONE.
     
    I found that compatibility mode was off in the uad control applet from before and turned it on but that didn't change anything.
     
    :Ron
     
    P.S. For what it's worth I may not be running the last uad-1 software.
    check later.
