**Beijing Photek S&T Development Co., Ltd.** (北京福托科技开发有限责任公司 *Běijīng Fútuō Kējì Kāifā Yǒuxiàn Zérèn Gōngsī*), also known as **Quadimension** (平行四界 *Píngxíng Sì Jiè*), is a company that consists of Chinese producers who originally created and distributed the *Quadimension* album series, which mainly featured a selection of Chinese VOCALOIDs. They collaborated with Shanghai HENIAN Information Technology Co. Ltd. to create a voicebank for their mascot and first Chinese VOCALOID, Xingchen.

## About

Quadimension began as a group that created doujinshi albums under the same name. These albums mainly featured Luo Tianyi, but began adding more VOCALOIDs since Quadimension 3's release in 2015 . Quadimension collaborated with a variety of producers who became members of the group, though not every person became a permanent member.

Their mascot appeared in some of the artwork in the album pamphlets. This mascot was known as Quadimensionko in the past, but eventually became their first VOCALOID, Xingchen. Quadimension commissioned Shanghai HENIAN to create a VOCALOID4 voicebank for her while they handled her character and marketing rights. She became the first entry of the Voicebank Customize Project.

Later, Beijing Photek was adopted as their company name. This was to keep the VOCALOID development and marketing business separate from the producer circle and to sound more professional.

In late 2017, Beijing Photek expressed in interest in expanding their cast to include a total of five characters. Haiyi made her debut in 2018 as the next character, but it was unknown what voice synthesizer engine she was for. Toward the end of 2018 and into the beginning of 2019, Cangqiong, Shian, and Chiyu were confirmed to be in production, but like Haiyi, the engine they were on went unrevealed. It was not until March 28, 2019, when Ddickky posted on Weibo that these characters (although Haiyi was omitted from the list), along with two Xingchen voice databases and an unknown male voice, were moving over to Synthesizer V.

On February 10, 2022, Ddickky mentioned that "TTS function" would be completed soon and that the MEDIUM⁵ 2050 dialogue's would be dubbed through the TTS voicebanks themselves rather than live voice actors. However, in order to do so, a speech voicebank would need to be made first, for which Beijing Photek did not yet have sufficient funds at the time.
