Hatsune Miku
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. The name of "Hatsune Miku" was conceived soon after the Vocaloid 2 announcements, when an English and Japanese vocal were developed for the character. The intended design was delayed and later used for Megurine Luka instead. Miku was intended to be the first of a series of Vocaloids called the ""Character Vocal Series"", which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.
Vocaloid 2
Megurine Luka was the third and final member of the Character Voice series. She was noteworthy for being the first vocal capable of both English and Japanese speech. She was released on January 30, 2009, and was codenamed "CV03" prior to release. Her English vocal initially did not have a full library and was capable of only 2,200 words, though she was later updated to fix the problem. It is notable that her package was originally going to be called "Hatsune Miku", designed when Vocaloid 2 was first announced to be a bilingual English and Japanese vocal, being the first planned member of the Character Voice series. Her provider is Yū Asakawa.
