Manami Matsumae (松前 真奈美), was born on December 25th, 1964 as Manami Goto (後藤 真奈美). She attended the Osaka University of Arts and graduated in 1987. In April, 1987, at the age of 22, she was hired by Capcom to work on the audio team. Matsumae stayed at Capcom until she left in January, 1990, at the age of 25, in order to become a freelance composer. She composed numerous soundtracks for ASCII, and HAL Laboratory, as well as various other companies.
Matsumae said that, rather than use pop music of the day, she used images from the games she worked on as inspiration for her composition process. However, some of her favorite bands include Queen, Pat Metheny Group, Mezzoforte, Maurice Ravel, Muse, and Nikolai Kapustin. She is married to Kimitaka Matsumae who is also a videogame musician.
The nickname "Manami Ietel", found in the credits of Mega Man I and II, comes from Matsumae's tendency to say to her superiors and elders, "Sore, ietemasune!" ("Exactly!" in Japanese). Without her knowledge, one of the programmers extrapolated the "iete" part of the phrase to "Ietel" for her nickname.
Manami used a sound engine programmed by Yoshihiro Sakaguchi. This was a difficult task because she had to program the music in 6502 assembly. According to Manami, she first worked on Ide Yousuke Meijin no Jissen Mahjong, composing one song as an audition for the Capcom staff, who later decided to let her work on Mega Man because of her song.
