On June 26, 2020, an update to Synthesizer V Studio for GENBU was announced on the Dreamtonics livestream[1] with a July release. On July 15, GENBU's complete voice database was released for Synthesizer V Studio. Options for a bundle with the Synthesizer V Studio engine were offered on ANiCUTE to members only. On July 30, GENBU received a Lite voice database, which was a free version that was ideal for trying him out.

On October 30, AH-Software Co. Ltd. announced in a press release that GENBU would be made available for Japanese users soon.[2] [3]


On January 21, 2021, GENBU was officially made available on AH-Software's shop as digital copies.[4] They also gave him his own character page and a new key visual.[5]

On May 5, a doujinshi circle known as VirVox Project, operating under the permission of VOLOR,[6] released the full image of GENBU previously used by AH-Software Co. Ltd. for his product page. The image revealed that GENBU appeared to be an alias and that his actual name was Kurono Takehiro (玄野武宏)[7]. He was planned to be part of VirVox Project's male voice synthesis character-centric group.[8]

On August 1, VirVox Project announced that a crowdfund campaign for GENBU's Synthesizer V AI voice database would be launched in Mid-August.[9] When asked if it was possible for overseas fans to participate, VirVox Project confirmed that the chosen crowdfunding site allowed overseas support, though also noted that because delivery prices were costly, tiers focusing on digital content were planned.[10] However, this did not dismiss the idea of physical goods for overseas users entirely as VirVox Project was still considering which service to use. They mentioned FedEx, EMS, or partnerships with overseas companies as potential options.[11]

On August 7, VirVox Project noted that due to circumstances, the announcement regarding the details about the crowdfunding would be postponed.[12] It was later noted that there was a discrepancy in the final stage of the crowdfunding adjustments, which VirVox confirmed that they decided to start readjustments once again, hence postponing the date. They noted they would do their best to resolve the issue as soon as possible.[13] VOLOR also noted that they would be working with VirVox to resolve the issue.[14]

On August 22, VirVox Project uploaded a press release in regards to the crowdfund for the AI voice database. The organization noted that they were trying to obtain the necessary permissions through a third party, but there were discrepancies with the latter who requested the proper consents. This led to a misunderstanding that VirVox Project obtained the required permissions, thus making the announcements for the crowdfund event. After the announcement, they learned that they did not have the proper consent, leading them to later announce that the crowdfund would be postponed. As there were ongoing discussions between VirVox Project and the third party organization, it was decided not to pursue a crowdfund for GENBU's AI voice database, rather implying that he may be produced through another method.[15]

Package details as noted:
GENBU retains around the same sound as his original Synthesizer V voice database release. He has a calm and soothing voice.[19] According to AH-Software, GENBU is noted to have a powerful treble, while the bass is more sweet and gentle. Dynamic singing expression is possible with his voice.[20]

Vocal traits as noted:
  • AH-Software noted that GENBU could be used for a variety of genres.
  • By using a group of soft falsetto phonemes together, GENBU can sing with a more delicate expression.
  • The recommended tempo was not included on the product pages nor database. VirVox Project gave an estimate in September 2021 and noted that it also depended on tuning.
