Pitch changes while exporting

Hi everyone,

I have an issue that might be discussed before, and I didn’t find an answer to it here.

I have sampled some sounds ( one note ), and after I exported it I noticed that all of them were tone/semi tone up.

I changed the sample rate in all devices (computer, External sound card, setting in cubase) and all of them are :48,000 and 16 bit.

I would greatly appreciate you to assist me with this issue…

Thanks a lot,
