GarageBand iPhone is suddenly wrong key.

GarageBand iPhone iOS 26.1 is suddenly playing I the wrong key.

i have a project with real instruments and GarageBand keyboards. I played the keyboards note for note. Suddenly yesterday all the GB instruments are in the wrong key. I have never touched the key settings and it doesn’t matter if I toggle the follow key on/off. Please help! How can I restore so it plays the notes I recorded?

Thank you Jesper
