## History

The earliest instance of Ryo's voice database production was around July 2021, with Eclipsed Sounds, LLC assisting Dreamtonics Co., Ltd..

On January 27, 2022, in the later portion of an AH-Software Co. Ltd. livestream that was launched to celebrate the release of Kyomachi Seika for Synthesizer V Studio, and Tohoku Zunko and Tohoku Itako for CeVIO AI, after showing the unknown English male (who would be later known as Kevin) who was introduced in 2021, Tomohide Ogata noted that they were announcing some news about something that had not been shown before. There, a new Japanese male AI voice database was heard singing "Tsubasa" and it was noted that he was a work-in-progress, with hopes that he could be released to people soon.

Kevin and the Japanese male, finally introduced as "Ryo", were suddenly released on February 4 as digital packages through AH-Software and Dreamtonics's new international official store. Up until February 6, users ordering from the Dreamtonics Taobao shop could receive a special New Year's discount for 100RMB off the regular prices. These were applicable for Kevin, Ryo, and their bundle sets with the Synthesizer V Studio Pro editor.

On June 13, Dreamtonics announced that they launched a new official store for the Chinese market built on WeChat's Mini Program. Users would be able to purchase the Synthesizer V Studio Pro editor and Dreamtonics' vocals through the application in a convenient manner, enjoying the automatic real-time distribution shopping experience. From June 13 to July 13, users were able to take advantage of unlimited 10% off coupons in the new store. It was later clarified that the decision to open this new shopping option was made due to Taobao's new restrictions on the sales of virtual goods as of April 2022, especially for restrictions on shipments without logistics since virtual goods would need to be delivered via email.

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

On July 21, Ryo 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). 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 his 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 Ryo (as well as other affected AI voice databases distributed by them) by logging in to their respective websites.

### Updates

Ryo AI v102 - March 25, 2022
A free update for Ryo was released following the Synthesizer V Studio 1.6.0 update. This enables him to use the new Vocal Mode options. Six variations were included: Open, Soft, Airy, Clear, Nasal, and Resonant.

Ryo AI v106 - July 21, 2022
A free update for Ryo was released following the Synthesizer V Studio 1.7.0 update. This enables him to use the new High Dynamics Voice Models and AI Retakes features.

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

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

Ryo AI v109b - February 6, 2023
A free update for Ryo was released following the Synthesizer V Studio 1.8.1b1 update. This improved the neural vocoder for male vocals in general, which results in an enhanced sound quality in the bass range.

Ryo AI v109 - February 16, 2023
Final version update compatible for Synthesizer V Studio 1.8.1 and improves the neural vocoder for all male vocals, including Ryo, which results in an enhanced sound quality in the bass range.

Ryo AI v110b1 - April 18, 2023
A free update for Ryo was released following the Synthesizer V Studio 1.9.0b1 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.

Ryo AI v110b2 - May 23, 2023
A free update for Ryo was released following the Synthesizer V Studio 1.9.0b2 update. This version of the vocal allowed for compatibility with the engine's second beta, which focused on rectifying several design issues identified by the user base in the 1.9.0b1 post-release survey.

Ryo AI v110 - June 21 2023
Final version update compatible for Synthesizer V Studio 1.9.0 and enables Ryo 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.

Ryo AI v111b1 - August 2, 2023 A free update for Ryo 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.

Ryo AI v111b2 - September 28, 2023 A free update for Ryo 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.

Ryo AI v111 - October 19, 2023 Final version update compatible for Synthesizer V Studio 1.10.0 and enables Ryo to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v111b1 and v111b2's notes) if the beta version was not installed previously.

Ryo AI v112 - October 26, 2023 A free update for Ryo was released that added support for the Japanese language to the rap feature.

Ryo AI v113b1 - December 18, 2023
A free update for Ryo was released following the Synthesizer V Studio 1.11.0b2 update. This implemented support for the Spanish language in the Cross-Lingual Singing Synthesis feature.

## Voice Database Information

### Voice Databases

Product Information
**Optimum**

  **Genre:** Pop
**Versions**

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

Ryo is a masculine baritone Japanese voice database that is described to be warm and gentle. As expected of an AI voice database, this enables him to sing with a more human-like and realistic voice.
**Vocal traits** as noted:

* While Ryo has a good and strong middle-range suited for pop music, Dreamtonics stated that he is flexible enough to be used in various genres and tempos.
* 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.

**Phonetic notes** as noted:

* Phoneme format: Romaji
* Through Cross-lingual Singing Synthesis, Ryo can sing in not only Japanese but also in English and Mandarin Chinese. Since the release of his v110b1 update on April 18, 2023, he can also sing in Cantonese Chinese with this feature; since his v113b1 update on December 18, he can also sing in Spanish with this feature. Cross-lingual Singing Synthesis is only available in the Synthesizer V Studio Pro Editor.

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

* As of March 25, 2022, Ryo became compatible with the Vocal Mode function introduced in Synthesizer V Studio 1.6.0. His v102 update included six variations:
	+ "Open"
	+ "Soft"
	+ "Airy"
	+ "Clear"
	+ "Nasal"
	+ "Resonant
* On AH-Software's database information page for Ryo, "Falsetto" was listed as a Vocal Mode variation. Currently, when opening Synthesizer V Studio, this is not the case as he only has the six previously mentioned modes. It was unknown if "Falsetto" was added intentionally to the webpage or if it would be implemented in a future update for Ryo. It was later removed from the webpage, though initial prints of Ryo's physical copies would still have "Falsetto" listed.

	+ AMD Athlon X4 845, Ryzen series or higher
* RAM: 2GB or higher
* Disk Space: 1 GB or higher (for installing one voice database)
	+ The amount of space required depends on the number of voice databases installed.
* Display: 1280 x 800 or higher
