On two of my tone test vids for new gear, I used the pro channel on X3.  Out of dozens of wav files I put together, I used the console emulator on two and both of the clips I used it on, have fuzzy glitches.   
 
Here is one I did a while back:

These are nothing critical, it's just I realized that they are the only tracks I used the console emulator on, and something glitchy happened to the waves.  Has anyone else had issues with the console emulators when exporting to 16 bit wav files?  The glitches didn't happen during regular playback, only when I export.   I've used the pro channels EQ etc and not had the glitches.  Only the emulators.
