Tap on a dark circle to turn it into a white circle. When you tap the white circle it becomes a white circle slightly displaced. Tap three times to return to the dark circle. Even if you tap the white circle long, it returns to the dark circle.
From Ver3.9, you can select the edit mode. Before Ver3.8, only the normal edit mode is available.
[Normal edit mode]
Tap the dark circle to change it to a white circle. If you tap the white circle, it will become a slightly offset white circle. Tap 3 times to return to the dark circle. Even if you long-tap the white circle, it will return to the dark circle.
[Move mode]
You can move the white circle by long-tapping it and then dragging and dropping it. It is convenient to move in this mode when you want to correct a semitone shift by one note or a beat shift by one note.

【Import from standard MIDI file】
Supported from Ver3.6. You can import files with the extension mid or midi. However, it depends on the data whether the import will result in a decent music box song. If it is solo piano data, it can be converted into a music box song relatively well, so please try various things.
