| Originally, the main screen looked like the extended song list below. Our final design adopts a splash-screen-like design in order to highlight the name of the app and reassure users that they're in the right place, while remaining functional with a prominent "new song" button. The background is intended to be aesthetically pleasing but unobtrusive. | ||
| We limited the main screen to three saved songs to avoid overwhelming users. The "new song" and "about" buttons remain prominent. Tapping on a song launches the compose screen, shown below. Our original design included small "rename", "duplicate", "export", and "delete" buttons on each song, but our paper and heuristic evaluations noted that such nested buttons were confusing and difficult to use on a small screen. We therefore replaced them with a menu accessed by tapping and holding for a second or so; this method is nonobvious, so we also included an instructional note. | ||
| Renaming a song works by replacing the name in the song button with an editable text box; when the user submits (presses enter) the song is saved. Duplicating a song creates a new song named "Copy of NAME" and enters rename mode on that song. Exporting uses native Android sharing functionality, which displays a list of possible transfer methods, including Bluetooth, email, etc. for the user to pick from. Deleting a song asks for confirmation, then slides the song button right rightward off the screen. (It would perhaps be preferable for all subsequent buttons to slide up until the deleted song was goneclearer for the button to shrink to nothing vertically with the buttons below sliding up, but technical features properties of the Android API make implementing this animation difficult.) |

| Exporting uses native Android sharing functionality, which displays a list of possible transfer methods for the user to pick from. A MIDI file containing the song is sent via the specified method. | ||
| If the user clicks the "see all" button, this screen is shown. It lists all saved songs, allowing scrolling and searching (the list updates as a user types in the search box). | ||
| The "about" button takes users to this screen, which is just a static message. | ||
| This is the compose screen for a song with no notes in it (e.g. a newly created song). | ||

| Record some notes. Here various tracks have been used to layer notes. | ||
