Rye Umemoto is a legendary composer who worked on a large library of Japan-only PC games in the 90s, in particular, NEC PC-98 computers.
The PC-98 used a slightly more advanced but older FM synthesizer soundchip that was a relative of the one SEGA used in the Genesis. The Genesis had the YM2612 and the PC-98 had the YM2608.
His work on Xenon, Desire, YU-NO, EVE Burst Error, Grounseed, etc were just fire. I think his works were the best during that era. I havent found a single one of his songs to be subpar. He definitely knew a good song fit the mood of the game, and didn't only have fancy arpeggios.
