This is an article about the CUL software for the VOCALOID3 engine.


CUL started off as the mascot for VOCALO Revolution. On June 8, 2011, Yamaha announced that CUL would become a real VOCALOID, with Eri Kitamura as her voice provider. The publisher was to be Internet Co., Ltd. On November 4, 2011, her first demo, a cover of a V3 GUMI demo "A Flash of Summer", was released on YouTube. Internet Co announced on twitter that CUL would be released around December 22. A second demo was also uploaded, this time a cover of V3 Gumi demo "Nightmare." Her third and fourth demos have also been uploaded.

In October 2014 in an interview when asked if any vocal produced any hard labor, Noboru mentioned that CUL was a hard vocaloid to produce as when synthesized she gave a result that was under quality. Noboru mentioned they had to scrap her original vocal and rebuild it from scratch. They had to re-build the vocal twice, though no re-recordings were involved.[1]

Mac UpdateEdit

In July 2013, Internet co.,Ltd announced a Mac update of this product for the VOCALOID NEO engine.[2]

Product Information
  Genre: Rock, Ethnic[3]  Tempo: 40 ~ 200BPM  Range: F2 ~ E4
Package details
Her voicebank is a powerful "young mature" female vocal type and is a professional VOCALOID vocal that was done as a Character Voice of Eri Kitamura.

The package also contains demo song data and illustrations.

Vocal traits as noted:
  • She is able to climb from low to high notes with ease.
  • Her voice has a powerful and raspy tone.
  • Her pronunciation was very clear compared to previous VOCALOID3 voicebanks, even in very short notes.
  • She's louder in lower and high notes, which allows her to not be too quiet.
  • One of CUL's highlights is her tempo range and she can cover some of the highest variety of musical genres because of it.
    • At 40 BPM, CUL is capable of the slowest tempo range of any VOCALOID3 vocal.
    • Her fastest tempo speed of 200BPM is also among a group of VOCALOID who jointly hold the title of 3rd fastest tempo range.
    • She has the 2nd largest tempo range with VOCALOID3 at a total of 160 BPM coverage, with IA and IA ROCKS having the largest at 165 BPM.
  • Once imported into VOCALOID3, XSY becomes available for her.
    • As of Ver.4.3.0 of the VOCALOID4 engine, with the exception of the original galaco and Rana vocals (which are not counted as an official Internet co., Ltd release) all VOCALOID3 and VOCALOID4 Internet Co., Ltd. vocals can XSY between each other.
    • In total if user was to own every VOCALOID3 and VOCALOID4 XSY capable INTERNET co., LTD vocal, this offers the equivalent of 812 additional voicebanks achievable via XSY. The total tone variation offered by the combined packages comes to a theoretical 841 voicebanks in total.[4]
    • Note that Users of the updated XSY list have to understand that as confirmed by Internet co., Ltd themselves, depending on the combination of the two vocals a level of extra unwanted noise may be generated.
    • This is particularly true more so when using the single voicebank releases from VOCALOID3 in XSY in either primarily or secondary roles. In addition to not being built with XSY in mind, they were never built with accompanying vocals in mind, so have no adjustments made to fit in with a accompanying voicebank of similar nature like the multi-bank releases did.
Software issues as noted:
  • CUL's voice is nasally and weaker in the abnormally higher octaves, leading to unpleasant distortion at times, as her vowels get weaker on higher notes outside her range.
