Complex stereo sound generator for sound effects and music synthesis

GetLoFi spotted a pretty interesting looking sound generator kit–

…Saratronics company based in Switzerland is selling these new Complex Stereo Sound generator kits for around 35 Euros shipped. My guess is that they are very similar to Soundgin modules, except a heck of a lot better. Typically modules like this are controlled by serial commands through an interface with a help of a PIC or AVR microcontroller that triggers the digital input pins of the generator. When those are shorted in a particular order they turn off and on various chip functions. The main sound generating IC in this case is SAA1099P,which I have never heard of, but apparently it packs quite a wallop…
