Hatsune Miku (Japanese: ?? ??) 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). The name of the character comes from merging the Japanese words for first (? hatsu), sound (? ne), and future (?? miku[n 1]), thus meaning "the first sound of the future", referring to her position as the first of Crypton's "Character Vocal Series". Pharrell Williams made a remix of Livetune's song "Last Night, Goodnight" featuring Hatsune Miku. On October 8, 2014, Miku made her American network television debut as she performed "Sharing the World" on the Late Show with David Letterman on CBS. Hatsune Miku is featured in "B Who I Want 2 B" produced by Sophie from Namie Amuro's album Genic. The 2016 Hatsune Miku Expo tour featured American electronic band Anamanaguchi as an opening act; to commemorate the tour, the band recorded a single track titled "Miku", which they performed live on the tour with Miku as an encore song. Big Boi (of Outkast) sampled Aura Qualic's song "DATA 2.0", featuring Hatsune Miku for his 2017 single "Kill Jill", also appearing in the song's music video.
