Yousuke Yasui: I think that Mr. Masato Nakamura’s original versions seemed to be created with sound source like E-mu Proteus if I am not mistaken, but when I try to listen, comparing them in this way, the porting to Genesis sound source was quite careful and yet, the gamelike brushup was also added and dropped in~.
Naofumi Hataya: Exactly! The person who created this timbre is President [Yukifumi] Makino, who also handled the SE. It is a splendid job. If I remember correctly, he seemed to also do the exchanges with SY77’s data…. I witnessed Mr. Nakamura sometimes coming to SEGA, and comparing and adjusting some ideas and opinions. (The novice me at that time)
