Actually, the PSX version of FFVII is /sampled and sequenced/ (like a surprising chunk of PSX music) from a Roland SC-88 MIDI module and part of the reason why a lot of video game music enthusiasts found the PC port of it interesting was because of the Yamaha XG support, an extension of General MIDI that was competing against Roland's GS extensions.

It had nothing to do with a 'lack of redbook', especially given the PC port shipped on disc and no one was releasing stuff on floppies anymore. It simply was common for Japanese computer games to support MIDI modules, even into the late 90s. They kept at it longer than Sierra!
