Hatsune Miku has performed at her concerts onstage as an animated projection hologram.
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito.
On April 30, 2010, a new add-on for Miku, called Hatsune Miku Append, was released containing a package of six different tones of Miku's voice: Soft (gentle, delicate voice), Sweet (young, chibi voice), Dark (mature, heartbroken voice), Vivid (bright, cheerful voice), Solid (loud, clear voice), and Light (innocent, heavenly voice).
To aid in the production of 3D animations, the program Miku Miku Dance was developed by an independent programmer.
The freeware software allowed a boom in fan-made animations to be developed, as well as being a boost for promoting Vocaloid songs themselves.
The Hatsune Miku Vocaloid 3 Japanese vocal library was released on September 26, 2013.A Mandarin Chinese vocal was released in September 2017, making Hatsune Miku the first trilingual Vocaloid product.Miku has been heavily promoted since 2008 and was originally aimed at professional musicians.Miku was intended to be the first of a series of Vocaloids called the "Character Vocal Series", which included Kagamine Rin/Len and Megurine Luka. She was built using Yamaha's Vocaloid 2 technology, and later updated to newer engine versions.She was created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone.
