[MIDIBox AY V1 - AY 3 8912 Module]
The MIDIbox AY V1 is stuffed with a General Instruments AY-3-8912 sound chip. The AY-3-8912 is a 3-voice Programmable Sound Generator (PSG). The AY 3 8912 and its variants became popular chips in many arcade games and was used on the Intellivision and Vectrex video game consoles and the MSX, Atari ST, Amstrad CPC, Oric 1, Colour Genie, Elektor TV Games Computer and Sinclair ZX Spectrum 128/+2/+3 home computers as well as the Mockingboard sound card for the Apple II family (etc.). The PSG contains 3 independent channels (A, B and C), a single noise generator, and a single envelope generator. Each channel includes a square wave tone generator and is capable of mixing any combination of the output from its respective tone generator with the noise generator and the envelope generator. Output from each of the 3 channels is then mixed together to produce the final audio output.
