During the Synthesizer V Studio Release Presentation on June 26, 2020, Beijing Photek confirmed that they were developing a new female voice database. She was expected to be released in the second half of 2020, but due to the impact of the COVID-19 pandemic, a specific date could not be given at the time. On August 1, Ddickky, the founder of Beijing Photek, noted that a demo for "minus" would be available later on August 12. Napstina, the company's annotator, confirmed that Minus was the female voice database that was hinted at in the initial Synthesizer V Studio presentation.
Minus made her debut on August 12. A design for her was shown in her first demo and used the concept for the Medium 2050 game, which was later made clear that this was her official design for the character and software overall. Her alternative name was confirmed to be "Xingchen Minus" (星尘Minus), but she was not voiced by Chalili due to major contractual issues that prevented Quadimension to record Xingchen and ZERO for Synthesizer V. Instead, she was voiced by Sawako Sui Hua Zi.
On December 23, 2021, it was announced that Minus, Chiyu, Shian, Cangqiong, Haiyi, and Muxin 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. The upgrades would be distributed to existing users for free and prices would be raised for new buyers soon due to the new inclusions.
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. On December 30, the voice databases were officially called "Synthesizer V Plus".
