Additional Installation Notes[]

Note these requirements only apply to the VOCALOID6 engine itself. Users need to check each VOCALOID package and its requirements before installation as some variation may occur between releases. When used as a VST/AU together with a DAW, the operating requirements of the DAW must also be met at the same time.

The license, much like in VOCALOID3 + NEO, VOCALOID4, and VOCALOID5 still allows the user to install on either Windows or Mac, though they can only have one or the other. The software must be uninstalled from its current OS to be able to install on the opposing one. However, note that regardless, only one license of VOCALOID6 is given upon purchase, therefore VOCALOID6 cannot be installed on multiple computers at the same time. This is the same for all voicebanks as well as the engine so while the user can have the installation on either Windows or Mac, they cannot install it on both or multiple computers.[18]

Similar to the installation of VOCALOID5, VOCALOID6 installs according to the version of the OS, meaning an English OS will result in the VOCALOID6 interface being in English when installed. Users wanting the software in any other language have to change their language OS to force VOCALOID6 to be installed in that language. This is different to VOCALOID3 and VOCALOID4 where the language was selected upon installation.[19]

HARUKA is the default vocal for VOCALOID6 and the engine will always revert back to her voicebank if an issue occurs, though this can be changed to other vocalists if the user doesn't want her to be the default vocalist. Users can also set the default vocalist for the VOCALOID:AI track and VOCALOID TRACK individually.[20]



Vocal libraries released for the VOCALOID6 engine.

Starter packs[]

Starter packs are VOCALOID6 releases that are sold with the VOCALOID6 engine included. The idea is this cheapens the first vocal a producer buys for the engine. Not all normal releases for VOCALOID6 have been given starter packs. Below is a list of vocals that have been sold as "starter" vocals.

VOCALOID6 PLUS Voice Bank Campaign

VOCALOID6 PLUS Voice Bank Campaign

VOCALOID6 Starter Packs, labeled as a "VOCALOID6 PLUS VOICEBANK SET" when purchased from the official VOCALOID SHOP include the VOCALOID6 engine as well as copies of SARAH, ALLEN, HARUKA, & AKITO and the VOCALOID5 vocals Amy, Chris, Kaori, & Ken. Purchasing from the Japanese VOCALOID SHOP allows users the option of purchasing the VOCALOID6 Editor in addition to one to two additional voicebanks at a 10% discount of the normal purchase price, excluding the upgrade discount, during the campaign period.[21] On the English VOCALOID SHOP, users have the option to select one of the current available PLUS VOICEBANK SET options, currently including: AI Megpoid, Po-uta and Fuiro.[22]

New Features[]

For a list of VOCALOID6s new parameters see Parameters

In addition to importing VOCALOID5 vocals, VOCALOID3 and VOCALOID4 vocals can also be imported.

As previously mentioned, all new purchases of VOCALOID6 from the official VOCALOID website come with four VOCALOID6 voicebanks: SARAH, ALLEN, HARUKA, and AKITO, as well as the four starting VOCALOID5 voicebanks Amy, Chris, Kaori, & Ken. This is reminiscent of VOCALOID5's debut with the inclusion of the VOCALOID5 STANDARD bundle, including Amy, Chris, Kaori, and Ken as well as the VOCALOID5 PREMIUM bundle including VY1 (VOCALOID5), VY2 (VOCALOID5), CYBER DIVA II and CYBER SONGMAN II.

VOCALOID6 offers new features including:

  • VOCALOID:AI: VOCALOID6 features VOCALOID:AI, an AI-based technology for generating a highly expressive singing voice that’s more natural than ever before.
    • See the main VOCALOID:AI article for additional details.
  • Direction: Users are able to use the new editing tools to freely edit the accents, vibrato, rhythmic feel, and more.
  • Vocal work, also known as Doubling: a function that is "essential for producing high-quality vocal tracks". With VOCALOID6, users are able to instantly create harmony parts.
  • VOCALO CHANGER, a function that allows users to import vocal data to replicate their own singing style as-is, as a VOCALOID voicebank.
  • Multilingual, a function that allows lyrics to be sung in a mixture of Japanese, English, and Chinese using a single voicebank. This gives users the freedom to write lyrics that "transcend language barriers".
  • ARA2 support: VOCALOID6 offers improved workflow with DAWs. Locator operations such as play and stop can be performed from the included plug-in.
  • Support for MIDI export: VOCALOID6 now allows users to freely export MIDI data that has been input.
  • Cubase AI support: VOCALOID6 comes bundled with Steinberg Cubase AI, so that users can enjoy making music right away.
    • Note: This option is excluded from the upgrade version discount.

VST Plugin Support[]

While VOCALOID6 does not support third-party Job Plug-ins, nor the inclusion of Cross-Synthesis, purchases of the AI Megpoid voicebank include the XSyn DAW-based VST3 plugin, developed by Internet Co., Ltd.. XSyn allows the blending of other VOCALOID6 voicebanks as well as voicebanks released by Internet Co., Ltd. from previous generations with the AI Megpoid product, to create a similar effect to that of the Cross-Synthesis feature from VOCALOID4.[24]


As with VOCALOID5, additional vocals are no longer referred to as "Plug-in Libraries Databases" (VOCALOID2 and VOCALOID3), "VOCALOID libraries" (VOCALOID4), Add-on Voicebanks and other names but are now simply known as "Voicebanks". A minor change of classification, though the use of "voicebank" is notable. Previously "voicebank" had been used in English speaking communities as a shorthand or common term to refer Vocaloid library database as a simplification. Later the term had slowly seen an increase in usage over time among studios. As noted by Gizmodo unlike all past VOCALOID versions, VOCALOID5 has the engine and VOCALOID Library are now more interlocked with each other, which is why it is now referred to as a "voicebank".[25]

Known Issues[]

Cross-Synthesis does not return in the VOCALOID6 engine.[26] VOCALOID6 also does not support third-party VST/AU plugins nor the VocaListener plugin.[27][28]



Software Reaction[]

The announcement and release of VOCALOID6 was met with surprise by the VOCALOID and Voice Synth communities, especially due to the lack of voicebank updates and new releases for VOCALOID5, and the amount of 3rd-party studios that departed VOCALOID after V5's release and migrated to other Voice Synths, with some having assumed that YAMAHA had quit VOCALOID as a result. They were equally as surprised when AI Megpoid was announced and released the same day as the engine's release. A number of producers commented regarding VOCALOID6, including ShareotsuP, OSTER project, Mitchie M, and Circus-P, and the Voice Providers of MEIKO and Megurine Luka commented on it as well, with Yuu Asakawa joking that a world where she doesn't have to sing is coming.

3rd Party Developer response[]

Upon release of VOCALOID6, Internet Co., Ltd. released the first 3rd-party voicebank for VOCALOID6, AI Megpoid as both voicebank only and Starter Pack options.[29]
