The app allows the user to set their own custom rhythms. These can be made up of whole notes down to sixteenth notes (including dotted notes, triplets, and ties) and rests of similar duration.

The user can specify the tempo with a keyboard, selected among a drop-down list of Italian tempo markings, or adjust it with buttons.

There are two different ways to save the rhythm and tempo. The first is to have it saved in the application's memory. The second is to have it copied to and pasted from the clipboard.

When the user is using the app, they can go to the import/export screen (accessed through the big "floppy disc" button icon) to copy or paste the rhythm and tempo.
