Inexpensive: The Mega32 microcontroller that we used is cheap and fairly easy to interface with a number of different standards, such as NTSC television and MIDI. Very little software is required in order to allow the user to print his or her sheet music.

        Expandable: Since MIDI is a standard digital music interface, the input to this system is not limited to just that of a keyboard. Any digital music that can be stored as MIDI can be displayed on the television screen and subsequently printed.
