Use SW9 to switch the music source between PS2_KEYBOAD and the
DEMO_SOUND block. To repeat the demo sound, press KEY1.
The TONE_GENERATOR can produce two tones, (1) String and (2)
Brass, selected by SW0. The audio CODEC used on the development
board has two channels, turned ON/OFF by SW1 and SW2.
DEMO_SOUND stores a sample sound for the user to play.
PS2_KEYBOARD processes user input from the PS/2 keyboard.
STAFF displays the corresponding keyboard diagram on the VGA
monitor when a key is pressed
TONE_GENERATOR represents the core of the music synthesizer
SOC.
