Audio Mixdown Playing In A Different Key

How do i fix this? I have exported many songs and never had this problem. The track plays fine in Cubase and then when playing back the Chorus is a key higher. I haven’t changed any settings and I don’t know how to fix this. I’ve read about sample rates but i’ve tried and nothing has worked,

Please help


Different Sample rate of the project and the audio device can cause this. But it would be the whole project.

Make sure you have no Transpose track involved. While playback it’s OK? Is it reproducible?

The Transpose on all tracks is set to zero. When i play the track in full on the software it plays totally fine but after export only the choruses go weird which I don’t understand. I haven’t changed anything for it to go strange so i’m stumped.
