Hatsune Miku
The Hatsune Miku Vocaloid 3 Japanese vocal library was released on September 26, 2013. It contained updates to all previous Vocaloid 2 vocals except "Vivid" and "Light". These were later released separately, though they were initially offered to anyone who already owned Hatsune Miku, Hatsune Miku Append, and Hatsune Miku V3. Once imported into Vocaloid4, all Vocaloid3 Hatsune Miku vocals could use the new Cross-Synthesis system (XSY) built for the new engine of Vocaloid 3. The voice was also imported into a device called "Pocket Miku", released on April 3, 2014.
