exs 24 logic x unwanted pitch change while playing

Hi

I used to work with the EXS 24 for years. Now I have a bigger issue.

When I sample something and I want to play it, the pitch is changing. When I record something the pitch is higher. When I listen to the reorded file the pitch is low again (as wanted). But I can't really work like this. It's totally useless like that. I tried to fix the problem, but couldn't make it on my own. Can somebody help me please? Thanks
