How can I set the tempo?

To change the accompaniment tempo, tap the button on the bottom right of the score screen. This will open a slider to choose your perfect tempo. You can change it whenever you want, even while the accompaniment is already playing.

Note that in Sight-reading and Magic Performance Mode the tempo of the accompaniment automatically adapts to your interpretation in real time.
