Open the player control panel.
Touch the "graduation hat" icon (lower left)
Turn OFF the key (changing) practice feature.

Thanks for your reply,
However, when I touch the icon, it does not turn off...
I do not know what I do wrong

Touching the grad-hat icon brings up the screen where you can activate or deactivate two different practice features.
Tempo, makes the player speed up each repeat.
And/or
Key, which causes a key change each repeat.
Slide both sliders to the left.
