6.9 Music Synthesizer Demonstration
This demonstration shows how to implement a Multi-tone Electronic Keyboard using DE2-70
board with a PS/2 Keyboard and a speaker.
PS/2 Keyboard is used as the piano keyboard for input. The Cyclone II FPGA on the DE2-70 board
serves as the Music Synthesizer SOC to generate music and tones. The VGA connected to the
DE2-70 board is used to show which key is pressed during the playing of the music.
 Press KEY3 on the DE2-70 board can play the next music file stored in the SD card.
