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.
Hatsune Miku: Project DIVA F
The game appeared at Sony's E3 2012 booth in June 2012 under the name "Hatsune Miku" so as to gauge interest for the game. Like the original the game primarily makes use of Vocaloids, a series of singing synthesizer software, and the songs created using these vocaloids, most notably the virtual-diva Hatsune Miku. "Project DIVA F" is the first game in the series to be multi-platform, with it being developed simultaneously for the PlayStation Vita and PlayStation 3, though there is some differences with regards to control schemes. A sequel, titled "", was released for PS3 and Vita on March 27, 2014 in Japan and released in November 2014 in North America and Europe.
