Most pieces in Metronaut are available in different versions based on Level of Difficulty and Accompaniment Type (for example with Piano or Orchestra). You can switch between these versions at any time.
The first time you enter a practice screen, Metronaut tries to choose the most appropriate version for you. The chosen version is visible in the music score title on the left. If there are other versions available, a downward arrow ⬇️ is shown next to the title. Tap there to see other available versions and choose them.
You can also access available versions from the Tool menu by tapping on ⚙️.
