I can't, sorry...I tried. But maybe I didn't try hard enough, like loading an X2 project or something that could make it happen.
HOWEVER, that doesn't mean your posting these videos isn't super-helpful. Cakewalk is looking into the Melodyne thing although the rendering aspect is within Melodyne so it gets a little complicated. They're kind of scratching their heads about what in SONAR could affect Melodyne's engine.
And here's something else interesting. I was finally able to reproduce what you showed on the Melodyne video. So I immediately did the same steps over from scratch so I could document them and provide a reproducible recipe. I could not get it to misbehave again, even when I canceled out of the project with no changes and did a system restore.
I'm sure you know this but just out of curiosity, have you checked for updated graphics card drivers? I cannot tell you how many weird things (including audio) have been fixed with a graphics card update.
And off topic, you have a pretty good voice for radio and narration...maybe there's a possible additional income stream in your future.
