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.
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.
