Yamaha's own history puts VOCALOID three years before Miku

The persona

Leon and Lola were the first commercial products built on Yamaha Corporation's VOCALOID singing-synthesis engine, three years before Crypton Future Media's Hatsune Miku made the same underlying technology famous. Yamaha's own 20-year VOCALOID history page dates the origin to 2000, when the company began developing a technology codenamed "Daisy" at its Toyooka factory in Shizuoka, first revealed publicly at the Musikmesse trade show in Frankfurt in 2003. The page states that in 2004 "VOCALOID(1) is launched to the general public at the NAMM Show," naming "Leon and Lola" as "English vocal libraries developed by ZERO-G and the first VOCALOID products."

What the documents establish

A contemporaneous archive of Yamaha's own vocaloid.com site, captured 2 February 2004, corroborates the date precisely: "'VOCALOID' was released by Zero-G Limited (United Kingdom) at NAMM Show from 15-18 January 2004 in Los Angeles," with a seminar introducing "VOCALOID product 'LOLA' and 'LEON'" and identifying East West Communications, Inc. as the United States distributor for the UK developer's voicebanks. Yamaha's retrospective page separately records that VOCALOID2 followed in early 2007 and that "Hatsune Miku, which uses that edition, was released by Crypton Future Media on August 31 that year," a release this site covers separately. The three-year gap between Leon and Lola's January 2004 launch and Miku's August 2007 debut is therefore fixed by Yamaha's own materials, not by later retrospective framing.

Character versus company

Leon and Lola were sold as voice tools, not as characters with names, personalities or social accounts; Zero-G Limited developed and marketed them as instruments for producers, distributed in the US through East West Communications. That is the opposite commercial model from Crypton's later decision to pair the same underlying Yamaha technology with an illustrated character and a name, which is what let Hatsune Miku become a persona rather than remain a plug-in. The distinction matters here: the technology's origin sits with Yamaha as engine developer, while any given voicebank's commercial personality, or lack of one, is a separate choice made downstream by whichever company licenses it.

What to watch

• How did Zero-G's original Leon and Lola libraries compare commercially to the character-driven voicebanks that followed them?
• What other pre-2007 VOCALOID products, such as Miriam or Meiko, shaped the market before Miku's debut?
• How does Yamaha's own account of VOCALOID's origin compare with Crypton Future Media's account of Miku's development?

Yamaha's anniversary materials make a case, in its own telling, for treating 2004 rather than 2007 as VOCALOID's real commercial starting point, even though it was Miku who later turned the format into a household name.
