Sample Editor Remains Empty
Since I installed Logic X, the Sample Editor seems not to work anymore. When I double click a Audio region in the Arrangement, the Sample Editor opens as it should, but it remains empty. No wave form is displayed there. If I activate any Flex Option in the Sample Editor, I cannot use it there (because nothing is being displayed). Instead I can only use in the Arrangement (what works fine for Flex Time, but doesn't for Flex Tune).
Any ideas what might be the reason and how to fix this issue?
Thanks a lot!
