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 3
A package containing 3 Japanese male vocals, Yuu, Kyo, Wil voiced by Minorun (Yuu), Nanox (Kyo) and Maui (Wil). They were released on June 20, 2013. Zola Project Neo was released on September 19, 2013. Yoshitaka Amano who previously had been an artist for the Final Fantasy series had been chosen as the illustrator for the package. The trio was designed to give producers a tool for creating songs that had been inaccessible up until that point. Zola Project were designed to offer the highest quality vocal possible and be accessible for both new and experienced Vocaloid users. Zola Project offered supporting roles for trio and duos, as well as harmonies. The boxart was designed as an "image illustration" and not "character designs" like the boxart for other Vocaloid releases. The voice providers who were sampled were given a different script to read from other vocals recorded and in addition received a half a years worth of vocal training before being recorded. The 3 providers who were chosen for the project were picked from 40 possible candidates. The product also came with a special plug-in for Vocaloid 3 called ""ZOLA_Unison" which is designed to help them sing together.
