History[]

2020[]

On October 10, 2020, it was announced that KAF would be collaborating with CeVIO AI. Her voicebank was announced to be distributed in winter of that year. A demo was uploaded on October 13[1] and a YouTube channel was created for her.[2]

On October 15, a questionnaire was announced. It would be used for determining the type of voice KAFU would have.[3] An accompanying video showcasing three potential vocals was also uploaded including: TYPE // A, TYPE // B and TYPE // C. Users were able to vote their preference for whichever vocal they liked the most. On October 18, the results of the questionnaire were tallied with TYPE // A receiving a rating of 65% of the total votes, TYPE // B receiving a 25.3% of the total votes and TYPE // C receiving a 9.7% of the total votes. It was announced that the voice provider, KAF, would be making the final decision of which vocal would be moving forward with development with reference to the survey results.[4]

On October 19, KAF followed up with a tweet regarding her own feelings on KAFU. She stated that while she was overall thrilled of the vocal as a fellow VOCALOID fan herself and had no concerns of KAFU "replacing" her, she felt as though some people looked at the two as inseperable entities that are indistinct from the other. For this reason, she made the final decision that TYPE // B would be the vocal to proceed with development.[5][6] After the the conclusion of the questionnaire results, KAFU's Twitter announced on October 27, that the development period would be extended with a delayed release date in hopes of satisfying both KAF and fans. KAFU was slated to be released within the first half of 2021.[7]

2021[]

On January 21, 2021 the official website for KAFU was created and revealed her full illustration, as well as information regarding pricing, purchase options and locations. It was revealed that KAFU would be releasing as starter pack with both the Song Voice and CeVIO AI editor as well as an original compilation album (see KAF+YOU KAFU COMPILATION ALBUM). The Song Voice is also available as a separate purchase.[8]

On March 14, KAFU's pre-order period was launched on KAMITSUBAKI STUDIO's BOOTH store.[9] A special retweet campaign was announced to commemorate KAFU's release in which 10 users would be selected to receive her CeVIO AI Starter Pack. [10] On June 24, her terms and guidelines for her character and voicebank usage were posted to her website as well as the official KAMITSUBAKI STUDIO website. [11][12]

She was finally released on July 7, 2021. She was also made available as a digital version on Vector Shop.[13]. On September 22, it was announced that the Vector Shop distribution for KAFU would stop on September 24 while the other websites would continue to distribute her voicebank.[14]

Product Information
Optimum

Trial Version/Starter Pack
  Starter Pack: Yes
Vocal traits as noted:

She has a youthful and nasal voice.

Software issues as noted:
  • Tends to have heavy pitch distortion on some notes which require pitch editing whatever the project's conditions are. The issue is worsening when on 2nd and further parts separated by silences on a same track, requiring to split the parts into different tracks, then to edit the remnant notes for which the pronunciation seems too strange.
  • Her nasal voice can cause her to have pronunciation issues on certain notes, or to inhale air excessively on some of them.
