is it quartus II can simulate sound wave ?

halo, I got problem here...

if using Quartus II , can i design the circuit to function something like music keyboard?

i don't know at all...just gt this idea...what components are needed ?

    The "music box" is the absolute minimum of sound generation hardware, just a digital output connected to a speaker, sending a square wave of variable frequency. You can either extend the design in software to a sigma-delta modulator or add a DAC or a sound chip. Many FPGA development kits have it.

    Then you are free to e.g. implement polyphonic instruments.

    thx :D

    coz i'm jz first time to do this...May I knw how to program using VHDL?

    i follow the music box 's note...but it show this --> Error: Node instance "divby12" instantiates undefined entity "divide_by12"

    what's meant by ?

    wat's wrong here?

    i'm using quartus II...
