Radio Shack used to sell something based on the ISD1520 chip. At one time, Digi-Key carried various models of this chip. Maybe that will help you get started.

Hello,
I am trying to find the easiest way to design a circuit that would allow prerecoded sound (piano, flute, animal sound etc...) to play whenever a key is pressed. I want to actually recreate those cheap keyboard you can buy for kids but make it easy to change the sound bank.
I was wandering if there was any "off the shelf" IC chip that would allow this type of application. My goal would be to design a keyboard that would have about 12 notes.
Thank you for you Help.
Rickydou.

1st thought.... Flash memory stick + mp3 player + keyboard D from BC
I though about this avenue, but how can I record 12 to 20 sounds (different animal sounds or different piano tones) and use another chip that would allow me to look into a lookup table to get the sound I need when I touch the first key and another sound for the next key.
Also I am looking to make a polyphonic instrument, so I want to play multiple sounds at the same time...
Any suggestions?
Thanks

I was under the impression that you could randomly access multiple stored sounds with the device, so if my memory is correct, that should not be a problem if you simply decode the keys to access particular stored sounds.
The polyphonic part or your requirement does make it tough. I suppose you could use multiple chips, but that doesn't sound friendly. Surely you can do what you want with a computer. Any computer, but one with a soundcard makes life easy.

I know the ISD chips from Winbond won't do what you want. (multiple simultaneous notes.) There was once a chip (AY-3-8910) or something like that, that would. But good luck finding one.
I think they were used in some early Atari or Commodore computers.??
