INTERNET Co. wanted to utilize the voice of a singer for the creation of a 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, now known as 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. On December 1st, 2014, when asked about VOCALOID4 updates, Noboru responded that they wished to update all of their VOCALOID3s to the new engine but had no specific schedule at the time. On March 31st, 2015, Gackpo was announced to have a VOCALOID4 update. This update contains his 3 voicebanks from the VOCALOID3 engine, but with added growl samples. It was confirmed that he would be released on April 30th, 2015.
