For a complete illustrated guide, please refer to the detailed tutorial on APP composition and settings.

Create a New Composition: On the APP home page, tap the pen and staff icon in the bottom menu to enter “My Creations.” Then tap the “+” icon in the upper right corner and select “Freestyle Composition.”

Song Information Settings:In the composition settings page, you can configure the song photo, track name, description, style, rhythm, tempo, visibility (public/private), and whether comments are allowed. When selecting the range, ensure it corresponds to your Muro Box model (e.g., 20-note or 40-note) so that the notes you compose fall within the playable range of the music box.

Edit Notes:Enter the piano roll composition interface. You can tap directly on the grid squares to add or delete notes (tap again to delete). Press and hold a note to adjust its position.

Save: After completing the note arrangement, tap the settings icon in the upper right corner. You can freely modify the track name, tempo (BPM), and sharing permissions. Finally, press “Save” to finalize your custom composition.
