Vocaloid 2

Vocaloid 2 is a singing voice synthesizer and the successor to the Vocaloid voice synthesizer application by Yamaha. Unlike the first engine, Vocaloid 2 based its output on vocal samples, rather than voice analysis. The synthesis engine and the user interface were completely revamped, with Japanese Vocaloids possessing a Japanese interface, as opposed to the previous version, which used English for both versions. It is noteworthy for introducing the popular character Hatsune Miku. It was succeeded by Vocaloid 3.

History
Vocaloid 2 was announced in 2007. Unlike the first engine, Vocaloid 2 based its synthesis on vocal samples, rather than analysis of the human voice. Due to time constraints, unlike the previous engine, it did not have a public beta test and instead bugs were patched as users reported them. The synthesis engine and the user interface were completely revamped, with Japanese Vocaloids possessing a Japanese interface, as opposed to all versions being in English, as was the case with its predecessor. New features included note auditioning, transparent control track, toggling between playback and rendering, and expression control. One's breath and voice could also be recorded into the library to make realistic sounds. This version was not backward compatible with the original Vocaloid engine, and its editor could not load libraries built for the previous version.

In addition to the PC software, Yamaha also offered an online service called NetVocaloid. This software was not localized, and Vocaloids made with either the English or Japanese in mind version would only be compatible with their respective version; for example, although Megurine Luka had an English library included, as a Japanese Vocaloid she was only usable with the Japanese version of the software.

Yamaha also released a version of the Vocaloid 2 software for the iPhone and iPad, which was first exhibited at the Y2 Autumn 2010 Digital Content Expo in Japan. This version of the software was later released using the voice of Yamaha's own Vocaloid called VY1. These products were launched as iVocaloid and i-Vocaloid, though the latter was later renamed to VocaloWitter.

Unlike the original Vocaloid software, Vocaloid 2 vocals could be imported into Vocaloid 3. However, it was not possible to import any Vocaloid 2 vocals into Vocaloid Neo or the Mac ports of Vocaloid Editor for Cubase. It was also possible to import Vocaloid 2 vocals into Vocaloid 4, either by importing them into Vocaloid 3 then Vocaloid 4, or via the use of the Vocaloid 2 import tool. Furthermore, while VSTi plug-in support for the software was provided, Vocaloid 2 would not work with some digital audio workstations such as Sonar, and had compatibility issues with others such as Fl Studio.

In total, there were 35 vocal libraries produced for Vocaloid 2; 17 in the Japanese version, and five in the English version.

Support for Vocaloid 2 ended in March 2016.

Critical reception
Vocaloid 2 was generally better received than its predecessor. John Walden of Sound on Sound had reviewed Leon, Lola and Miriam and noted that Vocaloid itself had no previous rival technology to contend with, and praised Yamaha for their efforts as Vocaloid was an ambitious project to undertake, considering that the human voice was more complex to synthesize than instruments such as the violin. In his review of Vocaloid 2, he referred to the original software engine in a passing comment stating, "Undoubtedly a remarkable and innovative product and, with experience and patience, was capable of producing results that could be frighteningly realistic." While he congratulated the improvements made in Vocaloid 2, he noted the software was still far from being regarded as a top rate singer. Particularly what makes Vocaloid difficult to sell as a product is the notion that the human ear can pick up faults in vocal speech. When reviewing Tonio, Sound on Sound writer Tom Flint argued that with the amount of time it takes to understand and learn how to use the software, it would be easier to hire a singer for half an hour to do the recording session. He, along with fellow writer John Walden during a review on Sonika, both stated singers don't have to fear losing their jobs just yet.

The Vocaloid 2 software was an instant success in Japan upon the release of the Hatsune Miku product. Bil Byrant of PowerFX, in an interview after the release of Big Al, noted that when they released Sweet Ann that they expected the electronica based music producers to use Vocaloid and were surprised that they were reluctant to embrace the software. At this point, a large Japanese producer base had formed and a large number of videos were being posted on YouTube. Hatsune Miku's success at selling 60,000 copies was also a noteworthy number, as at the time of Miku's release selling 1,000 copies of a software synthesizer was considered "a commercial success".

The Hatsune Miku product in particular went on to win several awards including;
 * She was nominated for and won an award in the "All About" awards of 2007.
 * Crypton Future Media picked up a BCN award in 2008 for their productions, with their sales reaching a 211% increase thanks to several products (One of which being Hatsune Miku).
 * In March 2008, Hatsune Miku won the "Digital Content" AMD award.
 * In June, Hatsune Miku picked up the 2008 MM Research Institute award.
 * At the DaiKon7 in August 2008, Hatsune Miku received another award.
 * Hatsune Miku was awarded the "Good Design Award 2008".
 * Hatsune Miku won the Grand Prize at the BCN AWARD 2009.

As reported in 2014 by Crypton Future Media's website "Sonicwire", Vocaloid2 was able to compete against the sales of Vocaloid3 vocals even as late as 2014, both Crypton themselves and fellow developer PowerFX vocaloids saw sales from both versions despite the improvements made in Vocaloid3.
