## History

Tsuina-chan resulted from a member of the "Hinomoto Oniko Project," Saki Ohenri, wanting to create a "rival" character to Oniko - as Oniko is a ogre, Tsuina-chan was conceptualized as an ogre hunter. Tsuina-chan made her official online debut on Ohenri's Pixiv on February 3, 2011 (the initial upload was since deleted). Her character is inspired by the "Tsuina" Event, which is an annual ceremony performed on December 30 each year. It is a ceremony designed to exorcise ogres and bad spirits, which was the basis of Tsuina-chan's character. Elements of the ceremony (instruments, wooden masks, traditional clothing) were all part of her character design. Since then, she had a voice drama series, "Tsuina, the Ogre Hunter", since August 2016. Tsuina-chan later had a crowdfunding campaign to become a VOICEROID in February 2019, and she successfully became a *VOICEROID2* product in November that year.

### 2020

On September 14, 2020, Tsuina-chan launched a contest for fans to design an outfit for if she were to become a singing synthesizer. The contest was set to last until November 14. Less than a month later, on October 5, Tsuina-chan's official Twitter account confirmed that she would be starting a crowdfunding campaign for a singing synthesizer later in winter. On October 30, Synthesizer V AI was announced and it was revealed that Tsuina-chan would begin a crowdfunding campaign for *Synthesizer V Studio Standard* and *Synthesizer V AI* voice databases later that year. The campaign began on December 4 and reached its initial goal of 5,000,000 yen in one day.

On December 6, the results of the design contest were revealed with the winning design concept illustrated by Twitter user ゆゆのすけ (@51714\_yuriyuri). Runner-ups were also announced for various awards including the: AHS Excellence Award, Mai Kadowaki Excellence Award, Feeling of Dynamism Award, Lovely Poster Award, Kouhaku Maruko Kobayashi Award, Tsuina-chan Meme Material Contest Award, and the Koufudaiji Temple Award.

By December 26, the crowdfunding campaign exceeded its 10,000,000 yen stretch goal for the development of a Synthesizer V AI voice database for Tsuina-chan. Additional stretch goals were added for each increment of 1,000,000 yen for the creation of new 3D models and additional voice recordings. She was expected to release toward the end of 2021.

### 2021

On April 22, 2021, in response to a fan's question regarding Lite versions, Tsuina-chan's Twitter replied that it was a possibility. On May 30, the initial sketch for Tsuina-chan's Synthesizer V design was released. A livestream for Tsuina-chan was confirmed to be launching on November 26.

On November 4, Tsuina-chan's website was updated and revealed her Synthesizer V design (later confirmed to be an alternative), which was noted as her "Diva Costume". Two additional full-body illustrations were presented on Twitter, which were noted to be her Standard and AI designs respectively. Pre-orders launched on the same day and her release date was confirmed to be November 26. According to her Synthesizer V character page on AH-Software's website, Lite versions were expected at a later date. On November 12, a list of all the sound samples that were packaged in her Synthesizer V libraries was revealed.

On November 19, both lite versions of the Standard and AI voice databases were made available. On November 20, some users confirmed they received their boxes early. Tsuina-chan was released on November 26 as intended.

### 2022

On March 25, 2022, after the implementation of Vocal Mode via Synthesizer V Studio Version 1.6.0., AH-Software announced that other AI voice libraries, such as Tsurumaki Maki, were planned to receive them. On March 26, when discussing the request forms to submit to AH-Software, Tsuina-chan's Twitter suggested for fans to put in requests for Vocal Mode implementation.

On June 30, it was announced that Tsuina-chan AI would be receiving a standalone physical package, which was expected to release on July 21, with pre-orders beginning on July 1.

On July 21, Tsuina-chan AI was one of the AI voice databases to receive an update for HDVM compatibility (a feature introduced in Synthesizer V Studio Pro 1.7.0, also released the same day), as well as access to four new Vocal Modes including: Attacky, Breathy, Crispy, and Soft, respectively.

However, some users complained about unstable voice-quality results when re-rendering in 1.7.0 projects saved under earlier versions of the editor that made use of her voice database (after updating it to v106). On July 22, Dreamtonics explained that by default, the AI Retakes feature favors "rich timbre and expressions over smooth and stable vocalization", resulting in inconsistent behavior relative to previous versions; as a workaround to stabilize the voice output, both Dreamtonics and AH-Software offered these steps below:

* Empty the selection.
* Open AI Retakes panel, go to Timbre tab.
* Under Takes -> Global Settings, reduce Expressiveness.

Responding to requests from users, both Dreamtonics and AHS made available for download that same day rolled-back versions of Tsuina-chan AI (as well as other affected AI voice databases distributed by them) by logging in to their respective websites.

### Updates

Tsuina-chan AI v103 - December 23, 2021
A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.5.0 update. This enables her to support cross-lingual singing synthesis.

Tsuina-chan AI v106 - July 21, 2022
A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.7.0 update. This enables her to use the new High Dynamics Voice Models and AI Retakes features, as well as giving her access to the Vocal Modes feature from the 1.6.0 update. Her Vocal Modes are named Attacky, Breathy, Crispy, and Soft.

Tsuina-chan AI v104 - July 25, 2022
A free downgrade for Tsuina-chan AI that removes HDVM compatibility, but retains the Vocal Modes introduced in v106.

Tsuina-chan AI v108b1 - November 10, 2022
A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.8.0b1 update. This enables her to use the new Diffusion Probabilistic Models (DPM) feature.

Tsuina-chan AI v108 - November 24, 2022
Final version update compatible for Synthesizer V Studio 1.8.0 and enables Tsuina-chan AI to use the new Diffusion Probabilistic Models (DPM) feature if the beta version was not installed previously.

Tsuina-chan AI v109b1 - June 21, 2023
A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.9.0 update. This implemented the new rap feature available for the English and Mandarin languages. Cantonese Chinese was added to the Cross-lingual Singing Synthesis feature as well as general improvements to the overall function, resulting in more accurate pronunciation that sounds closer to a native speaker when singing foreign words.

Tsuina-chan AI v109 - July 6, 2023
Final version update compatible for Synthesizer V Studio 1.9.0 and enables Tsuina-chan AI to use the rap feature (English and Mandarin Chinese only) and allow for Cantonese Chinese Cross-lingual Singing Synthesis if the beta versions were not installed previously.

Tsuina-chan AI v110b1 - August 2, 2023 A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.10.0b1 update. This enhanced pitch generation by utilizing Reinforcement Learning from Human Feedback (RLHF), translating to fewer off-key errors, making better use of vibrato, and creating more expressive transitions between notes. This also allowed for the use of the new "Enhancement" slider in the AI Retakes panel, which controlled the level of changes introduced by RLHF. For Synthesizer V Studio Pro users, feedback submission was enabled, allowing users to consensually share their preferred takes with only Dreamtonics for research and development purposes, where models trained with this feedback would be deployed in future voice database updates. Users may also opt out of this feature if undesired.

Tsuina-chan AI v110b2 - September 28, 2023 A free update for Tsuina-chan AI was released following the Synthesizer V Studio 1.10.0b2 update, which was the second beta version following version 1.10.0b1 that introduced enhancements to voice databases and integrated the latest user feedback via Reinforcement Learning from Human Feedback (RLHF). Regarding the editor, numerous reported issues were addressed for a more fluid experience. A new generation of pitch models were trained using the extensive feedback from users over the past month, and the new models offered greater accuracy in voice timbre reproduction, as well as a reduction in mispronunciations. Dreamtonics also focused on issues from the previous beta release that made Vocal Modes seem less distinct on certain vocals, ensuring clearer differentiation in the 1.10.0b2 update. The latest update also introduced a new feature in the Note Properties Panel that allowed for even division of a note into multiple syllables, proving to be a useful tool for songs with faster tempos.

Tsuina-chan AI v110 - October 19, 2023 Final version update compatible for Synthesizer V Studio 1.10.0 and enables Tsuina-chan AI to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v110b1 and v110b2's notes) if the beta version was not installed previously.

Tsuina-chan AI v111 - October 26, 2023 A free update for Tsuina-chan AI was released that added support for the Japanese language to the rap feature.

Product Information
**Optimum**

  **Range:** B3 ~ C5
**Versions**

  **Lite Version/FLT Available?:** Yes (Lite)  **Starter Pack Available?:** Yes  **Web Version Available?:** No
**Package details** as noted:

Tsuina-chan is a young feminine voice database based on the singing style of Mai Kadowaki. According to AH-Software and Dreamtonics, she has a soft, crisp, and slightly husky tone. As an AI voice database, Tsuina-chan is capable of sounding more realistic and human-like.
**Vocal traits** as noted:

* As per the Synthesizer V Studio 1.7.0 update launched on July 21, 2022, through High Dynamics Voice Models (HDVM), which later migrated to Diffusion Probabilistic Models (DPM) per the 1.8.0b1 update on November 10, AI voice databases may use AI Retakes to create multiple "takes" of a sung section with variations in pitch, dynamics, and timbre. This replicates the randomness of human vocalists, adds a more realistic feel, and allows users to find an ideal vocal without the need for "laborious tuning." This feature is only available in the Synthesizer V Studio Pro Editor.
	+ This does not apply to the Lite version.

**Phonetic notes** as noted:

* Phoneme format: Romaji
* A total of 317 Pitagoe voice files were specially recorded and included in the Tsuina-chan Synthesizer V package.
	+ List of recorded audio
* On December 23, 2021, with the announcement of Synthesizer V Studio 1.5.0, all AI voice databases would be able to use cross-lingual singing synthesis. This allows Tsuina-chan AI to be able to sing in not only Japanese but also in English and Mandarin Chinese using this new feature. Since the release of her v109b1 update on June 21, 2023, she can also sing in Cantonese Chinese with this feature. Cross-lingual Singing Synthesis is only available in the Synthesizer V Studio Pro Editor.
	+ This does not apply to the Lite version, thus restricting the voice database to Japanese only.

**Vocal Modes** as noted (Synthesizer V Studio Pro Editor only):
