Free Warp Is Changing Drum Pitch

Hi Folks:

I’m doing some multi-track drum editing based on this video: . The timing of the performance is pretty good; I’m trying to tighten it up a bit. As per the video I’m using the Free warp function. After I’m finished editing I bounce in place, Export, then Import back into a New Track Version, splitting the tracks back to their original mixer channels.

When I do, the toms are changing pitch. Three consecutive hits on one tom sounds like three different toms. Of course this isn’t happening on the original tracks. I’ve tried both elastique-pro and Standard-Drums modes and they both have the same problem. Any idea what might be causing this?

-thanks, Mark
