For the past year, this subject has evolved greatly but it is best to start with something a little simple.
Atari, the once mighty giant, had poor design choices after their success with the 2600. They have committed the biggest sin of all, which was neglecting the sound hardware for their 8-bit gaming console, the 7800.
While the 7800 had native backwards compatibility with the 2600, it lacked any sustainable sound chip other than the TIA chip from the 2600. However, the designers of the console alleviated this by having developers implement the POKEY chip in their cartridges with little costs. Although, this was dropped as soon as Jack Tramiel bought out Atari and restructured the company.
The POKEY chip was primarily used in Atari's arcade cabinets and 8-bit home computers. It was most notable known for being used in Lucasfilm Games's Ballblazer for the Atari 7800.
The theme Song of the Grid rip Russel Lieblich had some interesting origins, from the Wikipedia article:
Ballblazer's theme music, called "Song of the Grid" and heard between matches, was algorithmically generated, a technique designed by Lucasfilm Games team leader Peter Langston and called "riffology". The lead melody is assembled from a predefined set of 32 eight-note melody fragments, or riffs, which are put together randomly by an algorithm that also makes choices on several parameters including "how fast to play the riff, how loud to play it, when to omit or elide notes, when to insert a rhythmic break". The melody is accompanied by bassline, drums and chords, which are also assembled on the fly by a simplified version of the above approach. In effect the music plays forever, without repeating itself but without straying too far from the original theme. Langston, an experienced jazz, rock, and folk musician, said of Ballblazer's music: "One reviewer, an eminent jazz player [Pat Metheny], said it sounded like John Coltrane Post too long.
