Hatsune Miku
, sometimes referred to as Miku Hatsune, is the name of a Vocaloid software voicebank developed by Crypton Future Media and its official moe anthropomorph, a 16-year-old girl with long, turquoise twintails. She uses Yamaha Corporation's Vocaloid 2, Vocaloid 3, and Vocaloid 4 singing synthesizing technologies. She also uses Crypton Future Media's Piapro Studio, a singing synthesizer VSTi Plugin. She was the second Vocaloid sold using the Vocaloid 2 engine and the first Japanese Vocaloid to use the Japanese version of the Vocaloid 2 engine. Her voice is modeled from Japanese voice actress Saki Fujita. Miku's personification has been marketed as a virtual idol and has performed at concerts onstage as an animated projection (rear cast projection on a specially coated glass screen).
Virtual band
The members of virtual groups are depicted as animated characters, with their own personality, voice, history, and playing style. For example, Alvin, the leader of the Chipmunks, is considered mischievous, and Skeleton Staff's Guitarist Stanton is a party-going underachiever, furthermore, Freen in Green's bassist Sparky is sluggish and has been described as egotistical and pretentious, while Murdoc of Gorillaz is a middle-aged satanic bass player. Another example is Hatsune Miku who does not have a definite personality; because her way of being depends on the fans, her personality changes in each song made by the users of Vocaloid.
