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[edit | edit source]

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 stayed permanently.

In the album pamphlets, their mascot appeared in some of the artwork. 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 2019, the group moved onto creating Synthesizer V vocals.

In regards to VOCALOID5, according to Ddickky, when he heard the demos of the VOCALOID5 software, he felt that he heard no difference and that the technology was awkward. Regardless of this, Shanghai HENIAN could not allow a V5 update for Xingchen. When V5 later became available for sale, there didn't seem to be a large response to it. A V5 trial Japanese voicebank was sent in, but it was not any better. However, he noted that there may be inaccuracies with this information.

He went on to note that "if V5 collapses, could users still use V4?". He noted that after Beijing Photek's stock of the VOCALOID4 Editor was sold out, they attempted to restock but could not. When VOCALOID5 came out, Yamaha stopped distributing V4. Ddickky noted that the V5 Editor was expensive and Shanghai HENIAN was not yet selling the editor, so a restock was not possible.

In regards to the movement to Synthesizer V, he explained that it was not to simply keep producing vocalists, but to expand on Xingchen's world and story, and Haiyi's introduction was treated as a side project. After meeting and speaking with Kanru Hua, the developer behind Synthesizer V, they came to an agreement. Ddickky was to produce the voicebanks and market them so long as he paid for the license and did not compete for the market share nor abuse it.[1]
