History

On February 27, 2023, Dreamtonics Co., Ltd. posted a poem on bilibili along with an announcement that new songs and other news were expected for February 28 at 17:00 GMT+8. Details were not specified but the first part of the poem seemed to describe the beauty of song and pronunciation in music across any language. The second part described the role of melodies and pitches in music, emphasizing the importance of rhythm. On February 28, a technical demo announcing the future support for the Cantonese dialect and rap was uploaded. The final part of the demo showed a new male voice database rapping in Mandarin Chinese and English. On April 18, along with the launch of Synthesizer V Studio version 1.9.0b1, it was announced that "D-Lin", the Mandarin rap-focused voice database showcased in February, and "Ritchy", a newly introduced English rap-focused voice database, were made available via a Feature-Limited Trial. Ritchy's voice provider was also revealed to be MBanja Ritchy. The final release date for both voice databases was not yet announced.

On May 18, AH-Software Co. Ltd. launched a livestream that mainly focused on Tohoku Kiritan's upcoming VOICEPEAK release and other news. Ritchy's voice was featured in the livestream as a small showcase.

On May 23, Synthesizer V Studio 1.9.0b2 was launched, focusing on rectifying design issues as addressed by the user base in the version 1.9.0b1 post-release survey. Ritchy and D-Lin were still noted to only be available via FLTs, though their version numbers were indicated as "v011". On June 21, with the release of Synthesizer V Studio 1.9.0, Ritchy's image was revealed when using the latest version of his FLT v100.

Ritchy and D-Lin were released simultaneously on AH-Software's store, and on Dreamtonics' International, Taobao, and WeChat Mini Program on July 4. Ritchy was available for purchase individually or as a bundle pack with the Synthesizer V Studio Pro editor, and exclusively on Dreamtonics's Taobao shop, he could be bought as a dual voice database pack with D-Lin while excluding the editor. Ritchy's FLT was confirmed to still be available despite the final version's release, encouraging users to try him before deciding on purchasing.

Updates

Full Version

Ritchy AI v101b1 - August 2, 2023 

A free update for Ritchy 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.

Ritchy AI v101b2 - September 28, 2023 

A free update for Ritchy 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.

Ritchy AI v101 - October 19, 2023 

Final version update compatible for Synthesizer V Studio 1.10.0 which enables Ritchy to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v101b1 and v101b2's notes) if the beta version was not installed previously.

Ritchy AI v102 - October 26, 2023 

A free update for Ritchy was released that added support for the Japanese language to the rap feature.

Ritchy AI v103b1 - December 18, 2023 

A free update for Ritchy 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.

Ritchy AI v103 - April 4, 2024 

Final version update compatible for Synthesizer V Studio 1.11.0 which enables Ritchy to sing in Spanish through Cross-lingual Singing Synthesis if the beta version was not installed previously.

Free-Limited Trial (FLT)

Ritchy AI v011 - May 23, 2023 

A free update for the FLT version of Ritchy 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.

Ritchy AI v100 - June 21 2023 

A free update for the FLT version of Ritchy was released following the release of Synthesizer V Studio 1.9.0. This version of the vocal allowed for compatibility with the engine and its final adjustments based on feedback identified by the user base in the 1.9.0b1 post-release survey and for 1.9.0b2 in general.

Retirement

Ritchy was discontinued by Dreamtonics on March 21, 2025 with the release of Synthesizer V Studio 2 and Ritchy 2. As of March 23, several Japanese online stores like the AHS Store, DLsite, and SONICWIRE still sell the original Ritchy voice database, but stock may be limited. Also, his FLT version is still downloadable from Dreamtonics' Resources repository, even though it cannot be used on Synthesizer V Studio 2.

Package details as noted:

Ritchy is a masculine English voice database based on the vocal style of MBanja Ritchy. He was designed for rap and was marketed to promote the new functionality and experience of Synthesizer V Studio 1.9.0's Rap support. As expected of an AI voice database, Ritchy is capable of singing with a more human-like and realistic voice.

Vocal traits as noted:

• Ritchy was advertised to deliver an authentic street vibe.
• Ritchy is a versatile vocalist with a calm and impactful low range that has a unique release breath suitable for rhythmic spoken word and rap. He also has a gentle and swift-transitioning falsetto.
• He was noted to bring together tranquility and huskiness, allowing him to be flexible in not only rap music, but also other genres.
• His "Singing" mode was noted to capture MBanja Ritchy's characteristic husky timbre.
• With Diffusion Probabilistic Models (DPM), Ritchy can sing more realistically through changes in volume and breath, further enriching singing details, making each singing unique, and providing creators with more options. Through this mode, he can use AI Retakes to create multiple "takes" of a sung section 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: ARPABET
• Through Cross-lingual Singing Synthesis, Ritchy can sing in not only Mandarin Chinese but also in English, Japanese, and Cantonese Chinese. Since the release of his v103b1 update on December 18, 2023, he can also sing in Spanish with this feature. This feature is only available in the Synthesizer V Studio Pro Editor.

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

• Ritchy comes with three variations:
  • "HighTone"
  • "MidTone"
  • "LowTone"
• It should be noted that the Vocal Modes were geared to be more rap-specific and work best in Ritchy's Rap Mode.

System requirements as noted:

• OS: Microsoft Windows 11 / 10 (64 bit) and up; macOS 10.13 (High Sierra) and up; Ubuntu 20.04 (64 bit) and up.
• CPU: Intel Core i5 or higher, or equivalent AMD processor; Apple Silicon M1 or higher.
