I don't know what setting this is but no matter which song I open, whether it's a song I have created or a pre-existing one included, the backing harmony (chords) are playing back a whole step lower than what is displayed.

For example if the chord symbols displayed are :

C F G

It plays back what is sounding:

Bb Eb F

Is this a general preference I can change or use? The Key settings on the main page (below Choruses and to the left of Tempo) are working fine. It's not that setting and I would prefer to fix this issue rather than use that as a workaround.
I would appreciate any suggestions!

Thank you,

Felix
