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.
