When I pitch a stereo file some semitones up or down the result is always a mix of the original pitch and the new. If I then again open the item properties box, the field 'pitch adjustment' is back to zero again. I have to do the pitching again to get the desired result. A bug?
Tried it at my laptop back home and couldn't reproduce like I could on my workstation... here it works like a charm. Must be something machine specific. (the problem occured on a dell optiplex desktop)
