Pitch shifter in Premiere elements 11 is not working as good as it was in Premiere elements 7. Here's some of my issues:
When I change the pitch, the end of the audio is cut off/out of sync
When a clip is short, the audio won't play if it has the pitch shifter effect
When I split a clip with pitch shifter applied, the audio skips
I would like it if the pitchshifter would be more like the one that was in premiere elements 7.
Two questions... does your project match your video?

And, just what are you editing?
