Camui Gackpo

Kamui Gakupo (神威がくぽ) (note: on the Karen-T website his name is always written as "Camui Gackpo") is the official mascot character of Gackpoid (がくっぽいど / Gakuppoido) which is a singing synthesizer application software powered by Yamaha's Vocaloid2 and was published by INTERNET Co.,Ltd.
 * The naming about this product is very confusing. The Vocaloid software itself is under the official name Gackpoid, and Kamui Gakupo or Gackpo is the avatar character of the software drawn by the illustrator Kentaro Miura (三浦健太郎 Miura Kentaro).

History
Internet Co. wanted to utilize the voice of a singer for the creation of Vocaloid but felt it would be difficult to get a singer to agree. They consulted Dwango Co.,Ltd. who managed Nico Nico Douga, and Dwango suggested Gackt (神威 楽斗 Camui Gackt), a singer and actor, as he had previously provided his voice for Dwango's cell phone services. He lent his voice and named the Vocaloid, Gackpoid.

The product was originally intended to be released in June 2008, but though Gackt existed as a model for the Vocaloid, its illustrated avatar was yet to be determined. Popular manga author, Kentaro Miura, famous for his dark fantasy epic Berserk, was asked to do the illustration. Due to Miura's affection for Nico Nico Douga, he agreed to offer his services as a character designer for free.

Gackpoid was released on July 31, 2008. Two of Gackt's songs and three other songs are also included as samples.

An update with Gackpoid includes a new program, OPUS Express, for mixing vocal parts with accompaniment and phoneme data. There are 10 demo songs on the official site.

Vocaloid 3 Gackpoid
Internet co., Ltd have not announced if Gakupo will be extended like Gumi, however, they have confirmed if there is a demand for it they will consider producing one for him. Later it was confirmed all of Internet co., Ltd's Vocaloid 2 voicebanks would receive a Vocaloid 3 update.

During the Vocafarre, it was revealed that Gakupo's update would follow Lily's.

Marketing
Gakupo has a samurai aesthetic—the Vocaloid is clad in a Jinbaori, a kind of kimono which was used as a battle surcoat, with parts of Japanese armor, and carries a katana which was named “Music katana, Miburi” (楽刀・美振 / Gakutou Miburi). The patterns on its blade make sounds as a musical instrument when it is swung down.

Song Contest
In 2009, Gackt also challenged users of Vocaloid into a competition using Gakupo with the best song not only winning 10 million yen, but Gackt would also sing the song and include it on one of his next albums if he liked it enough. In 2011, the winning song "Episode 0" by mathru/KanimisoP and runner up "Paranoid Doll" by natsuP (SCL Project), were featured being sung by Gackt in his 39th single set for release on 7/13, 2011. The producer of the runner up song also received 300,000 yen while the producers of the other 8 top ten songs received 100,000 yen each.

This album is set to be released on the 13th July 2011, and will be Gackt's 39th single album under the title "Episode.0". The short preview for the original version of the song "Episode.0" in Gackt's version was released during the month of May 2011 Gackt-Episode.0 (Short PV However during the early days of the month of June an official video of the complete version of the song was uploaded on Nico Nico Douga Gackt-Episode.0 (Unofficial PV)

Phone Haiku
Internet Co. Ltd has released a service that offers Gakupo's voice for use with telephones, this service was first announced in April of 2009. The service is greatly limited compared to what the Vocaloid software allows normally but offers a chance for users to play with a limited version of Gakupo's voice for creating Haiku. The service was later updated for use with the PC in 2011. There is no fee for use of it and the service is open for use for fans across the world. The software application however can only be used in Japanese hiragana only and will take what is written as literal text, so for more complex patterns so great deal of thought may have to go into writing words. Internet Co., Ltd commented they intend to work with Twitter to open the service up more so others can share their works around the world. Users can download their creations for free as MP3's an unlimited amount of times.

Strengths
Kamui Gakupo was the first of Intenet co., Ltd's "Vocaloid Artist" series and was designed to be a professional vocal of noted quality. Gackpoid has one of the most quality voices in the Vocaloid 2 era voicebanks and one of the biggest depth ranges amongst the males. His pronunciations are overall smoother than most other Vocaloids and he was the only Japanese male vocal that could produce a low vocal tone until VY2's release. Also prior to VY2's release, he was the easiest Japanese male voicebank to use overall, however. His voicebank was praised for his more realisitc results in comparison to Cypton's "Character Vocal" series Vocaloids and offered the user much more professional results because of it. His voicebank has a reputation for being able use its Japanese phonetics to mimick the English language easier then most other Japanese voicebanks.

Weaknesses
His vocal results verus his difficulty levels were not always balanced in favour of inexprienced users. As is often the case with native Japanese speakers, Gackpoid does not have the phoneme "z" and "Z" in the phonetic system and they are replaced by "dz" and "dZ" as well as Megpoid.

Vocaloid 3
Is the updated version of the software (currently unreleased). Users will not have to purchase the Vocaloid Gackpoid voicebank to use it.

Popularity

 * Google Trends "Gackpoid"

In the Japanese fandom, he was slow to gain popularity due to a lack of demand for male vocals at the time of his release. Gakupo eventually gained popularity because of an increase in demand for male vocals and the popularity of his voice provider. Male vocaloids had not been developed for a long time and had so little demand at that time of Gakupo's release, owed to the failure of Kaito's release early on in Vocaloid's life circle. Gakupo was also the most expensive Vocaloid 2 Japanese vocal release, beaten at his time of release in price only by Zero-g's Prima Vocaloid. In mid-2010, he was reported to be on par with Crypton Future Media in terms of popularity, however, Gumi had overtaken him.

A independant Vocaloid search on Nico Nico Douga revealed that most Vocaloids had less then 1,000 videos uploaded on Nico Nico Douga in between July 1 and December 15 2011. Gakupo however did manage to be the 4th most popular Vocaloid when a mean count was donw with 375 views and 17 mylists.

Trivia

 * Because Gackt was a major singer, Gakupo was the most expensive Japanese Vocaloid 2 release, out of all the Vocaloid 2 voicebanks his release price overall was only beaten by Prima's.
 * Less experienced overseas fans often mislabel Gakupo as a "Gackpoid" rather then a "Vocaloid" and sometimes dismiss that he is a Vocaloid altogether. This is owed to the confusion over the name.
 * Gackpoid could be considered another contender for the insider joke "Big Al's syndrome" that overseas fans sometimes use to describe late Vocaloids. He was delayed for a month, however the term had yet to be invented.

 * First Vocaloid to be voiced by a major singer in Japan
