Drum: The drum beats a note when struck by the hammer tool. You can place between one and twenty drums and move them freely around the simulation window.

In the drum's Properties Box, you can change the note beaten by the drum. You have twelve notes to choose from: C (default), C#, D, D#, E, F, F#, G, G#, A, A#, and B.

The drum is one of nine sound sources in Sound Lab.
