History[]
2020[]
In January 2020, Ddickky confirmed that he learned about the second generation of the Synthesizer V engine in mid-2019. He wrote that it was in the works and was expected to be ready by the end of 2019, but it was pushed to around February or March 2020. He confirmed that Haiyi was the last to release for the first engine and that the next voice database would release for the new one. In addition, he had plans to gradually update each of Beijing Photek's first engine voice databases, and depending on the development costs, users who owned any of the four vocals would be able to receive the update for free or for a low price.[1]
On April 9, Chiyu's "SVR2" version was announced to be revealed in addition to information about the updated engine itself.[2] On June 26, it was announced that Chiyu and the other Beijing Photek Synthesizer V vocals would receive a ported update to Synthesizer V Studio. These would be released on July 10. Users who already owned Synthesizer V and/or the original MEDIUMāµ vocals received a special discount.[3]
On July 30, Chiyu was made available as a Lite voice database, which was a free version of her voice library that was ideal for trying her out.
2021[]
On December 23, 2021, it was announced that Chiyu, Shian, Cangqiong, Haiyi, Muxin, and Minus were expected to be upgraded with AI voice databases and would be able to support Mandarin Chinese, Japanese, and English (in correspondence to the Synthesizer V Studio 1.5.0's Cross-lingual Synthesis capabilities). It was clarified that the AI versions were trained by the Standard voice databases, and were not meant to be replacements for Standard nor would the update be available directly via the editor. As a separate type of voice database, the new libraries would need to be repacked in new installation packages, which required separate activation codes.
Ddickky commented that because Christmas was approaching and that Dreamtonics Co., Ltd. would be on holiday, it was thought that the voice databases could all be shipped on December 23 at 17:00 to directly align with the 1.5.0 engine update; however, he found this to be wrong. After Dreamtonics finished packaging the AI libraries, the activation codes were planned to be distributed by the Taobao agent, where users were to approach them, have their proof of purchase verified, and a new AI code would be sent. This was an entirely manual process and would have been done one by one. In addition, considerable time would have been needed to complete all six packages, so only one of them would have been finished on the 23rd, while the others would be finished later on.[4][5][6][7] The upgrades would be distributed to existing users for free and prices would be raised for new buyers soon due to the new inclusions.[8][9]
Later on, Quadimension commented that the release of the six AI voice databases was canceled for December 23 due to a lack of confidence about their performance as rushed products. A limited beta-testing would run first. The voice databases would be released after their performances were proven satisfactory. By then, Quadimension hoped to find an efficient way to distribute the AI activation codes.[10] On December 30, the voice databases were officially called "Synthesizer V Plus".[11]
2022[]
Throughout 2022, Cangqiong Synthesizer V Plus and Muxin Synthesizer V Plus received multiple examples demonstrating their capabilities as Standard-trained AI voice databases, including the Cross-lingual Singing Synthesis function. However, news about the development and future releases in general for all six characters were not available. On September 29, in response to a fan's question about whether the Plus versions of the six voice databases would be released soon, Quadimension wrote that it was probably not likely due to the qualities being unfit for commercial use.[12] On November 22, in response to a fan, Ddickky confirmed that the Plus series of voice databases were created with the intention of demonstrating the effects of training AI with Standard voice databases and were not meant to be released. The voice databases were sent to shareholders as a technology demonstration and not as a full product update. As these voice databases were to show the effects and technology of splicing AI training, they could not be noted as "Synthesizer V AI" as they would affect the brand quality of AI voice databases, thus the need of calling these "Synthesizer V Plus".[13][14]
2023[]
On March 11, 2023, in response to some fans' questions regarding the production of AI voice databases, Ddickky said that the other "AI" voice databases were promoted with Xingchen Infinity and that the voice providers were invited at the same time in the prior year. He said that he had no issue with the funding, but that some of the voice providers were concerned that the AI would be "stealing their jobs" while some were procrastinating with the work until recently. There was also a concern that the databases would not sound like the previous R1 and R2 "Standard" versions. He explained that an update for Xingchen V4 was needed as it performed poorly, so it must be launched even under the pressure of changing the singing voice style. For the other characters, however, the voice style change was always uncertain and it may create a reaction of resistance similar to Xingchen Infinity. Regarding the commercialization of the AI voice databases, Ddickky noted that the commercial sales of the voice databases have never been so profitable, so there wasn't enough motivation before. The commercialization would be determined after the production was completed, but it was expected to be handled similarly to Xingchen Infinity and would be sold directly since the technical workload and input cost were completely different. The AI voice databases may be sold for hundreds of yuan, which was one of the reasons why he thought they may not be suitable commercially. He also said that it was not a good time to speak from the perspective of business strategy and can only make a reminder in two months rather than rushing to ask every day. If there were no issues or delays, Chiyu AI and Minus AI were expected for 2023. Ddickky reminded fans that because there was no product line for the Standard-trained AI voice databases, they should not be expected for release.[15][16][17] On March 31, YouMao, Chiyu's voice provider, noted that as far as she knew, the AI voice database would definitely be completed.[18]
2024[]
On December 8, 2024, when asked by a fan in response to the announcement of Haiyi receiving a full AI voice database sometime in 2025, unofficial news outlet SynthV News responded that Chiyu AI had sounded too much like YouMao, leading Quadimension to respect the voice provider's wishes and postpone the voice database indefinitely, with a note that she "most likely" would be "re-recorded at [a] later date".[19]
2025: Usage on Synthesizer V Studio 2[]
On March 21, 2025, the day Synthesizer V Studio 2 was released globally, Quadimension's Taobao store announced that SVS2-compatible Plus versions of its MEDIUMāµ Standard voice databases (including Chiyu) were being offered for sale to customers, with delivery of activation codes and Baidu download links expected to take place within 10 days of order placement. The product listing also stated at the moment that customers who had bought the corresponding original SVS1 Standard voice databases within the past three months would only pay 50 yuan for the Plus upgrades, while those who had purchased the originals earlier within the past twelve months would only pay 100 yuan to upgrade; shortly later, it was added that for customers who acquired the originals earlier than 12 months ago, the upgrade from SVS1 Standard to SVS2-compatible Plus would cost 150 yuan for a limited time of just three months. The listing also advised not to rush to purchase the Plus upgrades, as any changes to the notice would be announced.[20][21]
Fans, especially those in the western vocal synthesizer community, felt uneased or outraged by the announcement of having to pay extra to upgrade their SVS1 MEDIUMāµ Standard voice databases to their SVS2-compatible Plus versions when, in contrast, equivalent SVS2-compatible AI-trained Standard voice databases by other companies (like VOLOR's GENBU and AiKO,[22] as well as Dreamtonics' own Saki Standard and AH-Software's complete Standard lineup), which were technically no different than Quadimension's Plus voice databases, could be obtained for free and downloaded into SVS2 after registering their original SVS1 activation codes into the My Dreamtonics website.
On March 23, Ddickky stated that he was still debugging the new SVS2 and Plus listing on Taobao, and that the voice databases would not be ready for days. Producer IrunaBara added on top of that statement that, even if the Taobao listing looked fine right now, the presence of new Plus options there were simply a glitch, and advised other customers to hold off on placing any orders.[23] Shortly later, the new Plus upgrade options were grayed out on the Taobao listing, preventing them from being selected.
On April 14, the MEDIUMāµ Synthesizer V Plus voice databases finally became available for free download (through the Synthesizer V Studio 2 Pro editor) to owners who registered the activation codes of their corresponding Synthesizer V Studio Standard voice databases into My Dreamtonics. Although compatible with the new SVS2 engine, they do not have access to the Vocal Mode function and do not support Korean Cross-lingual Singing Synthesis or any other Synthesizer V Studio 2-exclusive features, rendering the databases similar to those of first-generation Synthesizer V AI vocals imported into the new engine.
The Lite version of Chiyu Standard cannot be imported into (nor used on) Synthesizer V Studio 2, not even in its feature-limited trial mode; only her paid version can be imported and used there.

Synthesizer V Plus[]
There were no demonstrations for Chiyu Synthesizer V Plus.
Synthesizer V AI[]
There were no public demonstrations for Chiyu AI, in light of her sounding too much like her voice provider YouMao and being postponed indefinitely.[19]
Voice Databases[]
- Regarding the Lite version:
- Chiyu Lite may not be used commercially in any way
- When using the Lite version of this voice database, "This work uses the Lite version" must be mentioned on any uploads.
- Chiyu Standard SolfĆØge:
- Chiyu Standard Lite SolfĆØge:
- A preview of Chiyu's Synthesizer V Studio Standard voice database (provided by the Dreamtonics website):
- Phoneme format: X-SAMPA
- Through Cross-lingual Singing Synthesis, Chiyu AI was expected to sing in not only Mandarin Chinese but also in English, Japanese, and any other subsequent languages. This feature is only available in the Synthesizer V Studio Pro Editor.
- This would have been an AI voice database that was trained by the Standard version and would not have been based on new recordings. Thus, there may be similarities between Standard and Plus.
- Through Cross-lingual Singing Synthesis, Chiyu Synthesizer V Plus would have been able to sing in not only Mandarin Chinese but also in English and Japanese.
- The traits may remain similar to her Synthesizer V Studio voice database, which includes her young yet mature voice with strong and powerful tones.
- Chiyu Plus is able to 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, she 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 2 Pro Editor.
- Phonetic format: X-SAMPA
- Through Cross-lingual Singing Synthesis, Chiyu Plus can sing in not only Mandarin Chinese but also in Japanese, English, Cantonese Chinese, and Spanish; however, as an AI-trained Standard voice database, Chiyu Plus does not have access to the newly-added Korean. This feature is only available in the Synthesizer V Studio 2 Pro Editor.
