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).
Vocaloid 3
Hatsune Miku had two releases for the Vocaloid 3 software. The first was a new English vocal released on August 31, 2013. The second release was an update on the Vocaloid 2 vocal, it contained 5 vocals, 4 of which were updated versions of 4 of the 6 Hatsune Miku append package vocals ("sweet", "dark", "solid", "soft"). There were two versions of the software released, one with and one without the English version included. It was released on September 26, 2013. Like Kaito before her, she also came with Piapro Studio.
The missing vocals from the Append package ("light" and "vivid") were originally offered for free as part of an early promo for those who had the Vocaloid 2 version and the Vocaloid 3 version of the Hatsune Miku vocals. They were later sold separately on the Japanese version of the on-line store Sonicwire.
