This article is about the first VOCALOID software known as a voicebank. If you are looking for the VOCALOID character then click here.


MEIKO and KAITO were originally developed by YAMAHA, with Crypton Future Media handling her commercial release. This was much in as the later VY1 and VY2 vocals were left to Bplats, Inc. to sell.[1]

MEIKO and KAITO were originally developed alongside LEON and LOLA and intended for release for the software "Project Daisy", with MEIKO having the name of "HANAKO" for a long time.

On July 24, 2003, a CD album named "HISTORY OF LOGIC SYSTEM," (which included a song using Japanese VOCALOIDs commercially for the first time), was released. It was a duet song of "Ano Subarashii Ai wo Mou Ichido (That Wonderful Love Once More)," being covered by a prototype version of MEIKO and KAITO before their release.[2]

MEIKO sold 3,000+ units in her first year according to DTM magazine, which was out of the ordinary for a software synthesizer at the time. This was also far better than her counterpart Kaito, who had sold only 500 units. Another thing to consider is that for a commercial product to be successful, a software synthesizer had to sell only 1,000 units. MEIKO's success, followed by the success of Hatsune Miku, led Crypton to be focused on female vocals for their VOCALOID2 era voicebanks. It was also a common expectation that females would sell better than males, partly due to MEIKO's success.

When Hatsune Miku was on pre-order it was noted MEIKO and KAITO had no prospect of receiving updates and it was preferred to carry on with new releases. Hatsune Miku would be successors to the pair. However, in terms of sales of Hatsune Miku, Crypton Future Media would offer up preferential sales for users of MEIKO and KAITO if they were registered by the 9th of August, 2007.[3]

However, after Hatsune Miku's success, Kaito went into rediscovery, which put him on par with the sales of VOCALOID2 voicebanks. In 2008, while Kaito was 2nd place in the Nico Nico Douga best-seller award, MEIKO was struggling to keep popularity with the more modern female VOCALOIDs being released. By 2009 and up to 2011, while Kaito was almost constantly on the top 10 products page from Crypton Future Media, MEIKO was barely selling at all.

In 2012, Zero-G confirmed that all VOCALOID vocals were unsupported and due for retirement "in the near future."[4]

Product Information
  Trial/Demo Vers?: Yes
Package details as noted:

MEIKO is the counterpart to KAITO and part of Yamaha's "VOCALOID" series. She is designed to be a professional vocal aimed at professional producers and produced powerful and realistic results.[5]

Crypton Future Media, Inc. released a "couples bundle set" (male and female) which included MEIKO, KAITO, LEON and LOLA. A loop sample set was also supplied with the 4 voicebank bundle.[6]

Vocal traits as noted:
  • Her voice has been said to be steady, straightforward, and suitable for any musical genre. Her vocals strength was unique among the Japanese vocals for a long time.
  • MEIKO is difficult to master due to a lack of clarity in her vocals, which results in her voicebank being difficult to tune well.
  • The difficulty in mastering her voice was outweighed by her potential, even up against the later Hatsune Miku vocal.
Software issues as noted:
  • Because of the gap between release, MEIKO has overall slightly less quality than KAITO because of improvements made during KAITO's development.
  • Although she used Japanese phonetics, the menu was not in Japanese and instead was released only with the standard English interface.
  • As noted while Crypton Future Medi were developing Hatsune Miku, MEIKO had a habit of producing thick and ugly vocals, Miku was easier to manipulate in terms of gender/age.[7]

A trial version has been released of this product.


Like all VOCALOID vocals, MEIKO had her own interface design.

In 2006 a competition was held, with winners being awarded a special signed version of the interface.[8]
