MEIKO is a Vocaloid DTM(Desktop Music) software created by Crypton Future Media and she utilizes the older Vocaloid engine developed by YAMAHA. Her voice is based on a Japanese female singer Meiko Haigō (拝郷 メイコ, Haigō Meiko), which is steady, straightforward, and suitable for any musical genre

Crypton placed this product on the market with a box art which depicted Meiko in anime form. This character had nothing to do with the singer's image, but her appearance appealed to the mainstream audience and the software sold well. The success of this marketing strategy influenced the development and art style of other Vocaloids such as Kaito and Miku Hatsune.

Until Luka appeared, she was also the most mature sounding of the Japanese voicebanks. She is fit to sing anything from pop, rock, jazz, R&B to children's songs. Vocaloid digital sound is still heard in her voicebank and editing may be needed, although it is less apparent in Meiko then Lola's. Her overall tone of voice is more fluid and gives her a large vocal range, it lacks the flatness of earlier Vocaloids and gives her a contrast to Miriam's light and soft voice and Lola's deep, mature tone.

                                   I love how Meiko's voice was used here . . . it's so peaceful and calming

 

 

                          In order of appearance, MEIKOthen Meiko Sakine (younger version, considered her sister                                                here, I guess, and   Meito Sakine (genderbent Meiko).

                                                         it's such a beautiful song!(clear form)
