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).
Hatsune Miku: Project DIVA X
Live Quest Mode involves the player completing quests by playing songs. In between missions, short interactions and visual novel style dialogues may play out between the player and Vocaloids. The mode consists of two main types of quests - Area Quests and Event Quests. Area quests simply require a song to be completed while gaining a certain score. Later quests throw in other challenges (such as the "cool" pop up randomly changing to "miss" and "sad"). Event quests have special requirements such as requiring the player to play a "special live" consisting of 3 songs in a row. The game also features new "medley" songs, which are fully playable compilations of popular returning and new tracks. The full versions of the songs comprising the medleys cannot be played in full.
