Sv: [sdiy] OT: Record/playback module

As a matter of fact i'm sitting here next to a breadboard with a
PIC16F870 connected to a ISD2560 sound recorder/playback chip and the
VCO from a 74HC4046 for pitchcontrol. 
CV-control and random playback is a piece of cake! :)
I don't know if the ISD-chip is obsolete but if it is I think there are
more chips in that family. It may be called Winbond nowadays. My chip
records 60 seconds of audio at 8khz and has a 10 bit adress bus for
playback/recod position control.

Hi all,

Sorry this kind of off-topic - I'm looking for a circuit that can record

4 or 5 separate audio samples, each about 10 seconds long, and 
incorporating a random play feature. I've googled and found the 
ISD4002-120 - if anyone has any other advice/pointers I'd be most
grateful!

James
