The AY–3–8910 Programmable Sound Generator chip was created by General Instrument in the early 80s. It handled music and sound effects duties as part of many early arcade games, pinball machines, and home game consoles. We became fascinated with it after being charmed by the sounds of the chiptune scene (shout-out to Dubmood!), and soon started dreaming of turning the AY chip into a standalone synth. The AY-SYNTH is the happy result.
