Uematsu's approach to composing the game's music was to treat it like a film soundtrack and compose music that reflected the mood of the scenes, rather than trying to make strong melodies to 'define the game', as he said that approach would be too strong when placed alongside the game's new 3D visuals. Eight are reserved for sound effects, leaving sixteen available for the music. The Super NES only has eight sound channels to work with, and the PlayStation has twenty-four. Uematsu then decided that the higher quality audio was not worth the trade-off with performance, and opted instead to use MIDI-like sounds produced by the console's internal sound sequencer, similar to how his soundtracks for the previous games in the series on the Super NES were implemented.
Originally, Uematsu had planned to use CD quality music with vocal performances to take advantage of the console's audio capabilities but found that it resulted in the game having much longer loading times for each area. The musical score of Final Fantasy VII was composed, arranged, and produced by Nobuo Uematsu, who had served as the sole composer for the six previous Final Fantasy games.
