An unnamed male voice database was planned since March 2019, though no further information was given. On June 26, 2020, a sample of his beta voice database was featured in the Synthesizer V Studio Release Presentation and it was confirmed that the final version would be better. He was announced to debut some time soon. It was later confirmed that he was voiced by YuukaNeko.
The vocalist's name was confirmed to be Muxin and his concept art for the Medium 2050 game was revealed on July 14. In this concept, he was confirmed to be 14 years old, but in the game, he would be 16.
On August 1, Ddickky noted that a demo for Muxin may be available the next Friday, August 7. His design was revealed and he became available for preorder that day. He was scheduled to release on August 15.
On December 23, 2021, it was announced that Muxin, Chiyu, Shian, Cangqiong, Haiyi, 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. 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".
