In the late 1990s and early 2000s, a MIDI file was the most bandwidth-efficient way to add music to a website. The S-YXG50 became the de facto standard for webmasters composing with tools like Cakewalk Express or Voyetra . If you visited a fan site with an auto-playing Final Fantasy MIDI, the composer likely mixed it on an S-YXG50. The Demoscene also adopted it for “tracked music” exported to XG MIDI, enabling tiny file sizes with rich sound.
