U-he Diva Detunes Upon Pressing Play

Hi,
Just got Diva and it seems to drop it's pitch reference down two (2) cents upon the second press of the midi controller start button or space bar. It's consistent. First starting of sequence the clip plays as recorded. Second press of play button, the tuning drops a whole step and the clip plays "transposed" down 2 cents. (In fact, I can actually hear the clip drop the tuning in the sustain/fade out of the clip as soon as i hit stop.) It goes back to the correct pitch when I change the preset and then come back to the patch. Then it happens again.
U-he Support says they've heard of this before and it's always either the DAW's track settings or the midi controller settings.
I can't find anything wrong with either.
I'm using the VST3 version.
Thanks for any tips.
 

Okay, thanks shawker.
I'll try telling u-he Support about it again and see what they have to say about the VST2 vs. VST3 thing.
Thanks again.
