Vocaloid
Originally, Hiroyuki Ito—President of Crypton Future Media—claimed that Hatsune Miku was not a virtual idol but a kind of the Virtual Studio Technology instrument. However, Hatsune Miku performed her first "live" concert like a virtual idol on a projection screen during Animelo Summer Live at the Saitama Super Arena on August 22, 2009. At the "MikuFes '09 (Summer)" event on August 31, 2009, her image was screened by rear projection on a mostly-transparent screen. Miku also performed her first overseas live concert on November 21, 2009, during Anime Festival Asia (AFA) in Singapore. On March 9, 2010, Miku's first solo live performance titled "Miku no Hi Kanshasai 39's Giving Day" was opened at the Zepp Tokyo in Odaiba, Tokyo. The tour was run as part of promotions for Sega's "Hatsune Miku: Project Diva" video game in March 2010. The success and possibility of these tours is owed to the popularity of Hatsune Miku and so far Crypton is the only studio to have established a world tour of their Vocaloids.
Utau
Later, the UTAU software would have its own impact on Vocaloid and other vocal synthesizers, with a number of vocals either referencing UTAU or being produced for the engine to begin with. For example, Megurine Luka V4x was influenced by the UTAU vocal "Gahata Meiji". Wat from Crypton Future Media also spoke to someone very familiar with UTAU and said that the conversation was "very interesting". Macne Nana of the Macne series later would become both a UTAU voice and a Vocaloid voice. The voice provider of English Vocaloid Ruby, Misha, had previously produced a Japanese-language UTAU named Makune Hachi (MAKU音ハチ). In addition the vocalist for Dex, Kenji-B, created for UTAU and AkiGlancy, the vocalist behind Dex's partner Daina, gave her voice to a UTAU called . After the release of Vocaloid 3 vocal Tohoku Zunko, her two sisters Tohoku Itako and Tohoku Kiritan received UTAU vocals, Kiritan would later go on to have a campaign for her to become a Voiceroid.
