Vocaloid products

Kaito was the only one sold using the Vocaloid 1.1 engine; the previous Vocaloids before him were sold as Vocaloid 1.0, which he was also supplied with. However, he needed the additional Vocaloid 1.1.2 patch to work on the Vocaloid 1.0 engine.^[7] A patch was later released to update all Vocaloid engines to Vocaloid 1.1.2, adding new features to the software, although there were differences between the output results of the engine.^[8] Even though Kaito and Meiko were Japanese and sung using Japanese phonetics, the main interface was written in English for both English and Japanese Vocaloids.

Due to the success of placing a character on the box art of Meiko, the concept was carried over to her successor Kaito and later Vocaloids to encourage creativity; however, neither Vocaloid's box art originally had the intention to represent that Vocaloid.^[9][10] Though Meiko experienced good sales, Kaito failed commercially, causing less demand for male voices for a while after Kaito's initial release.^[11] However, sales eventually picked up and Kaito later won the Nico Nico Douga second best seller award of 2008.^[12] In 2010, it was reported that Meiko and Kaito were in the discussion to receive updates.^[13] Several updated vocal expressions have already been recorded for Kaito that year.^[14][15][16] In April 2011, it was confirmed six vocal expressions had been created for Kaito, two of which were dropped and the remaining four were being brought forward with one having reached alpha stage at that point. The Character Vocal (Hatsune Miku, Kagamine Rin/Len and Megurine Luka) series Appends had been created from the vocal performances of their voice providers; however the new Kaito Appends were created by adding echo, force, and tension to the samples.^[17]

Crypton released Hatsune Miku, on August 31, 2007. The second of the Character Vocal Series is the first dual Vocaloid Kagamine Len and Kagamine Rin, a Japanese male and female, released on December 27, 2007. On July 18, 2008, the updated edition of Kagamine Rin and Len, named "act2" was released.^[20] For a period of time, users who had bought the old version were allowed to get the new version for free. On June 18, 2008, beta demonstration songs using the new version were released on the company's official blog.^[21] The expansion disc is an entirely different software and does not affect the original Kagamine Rin/Len installation in any way, giving the user options to either use the old or new voice sets exclusively or combine their usage. Crypton Future Media have now retired the sale of their old Kagamine Vocaloid and it is now no longer possible to buy the software from them.^[22] This was also the very first Vocaloid update to be done for any Vocaloid. The third product of Crypton's Character Vocal Series is Megurine Luka, the first bilingual Vocaloid.

On April 30, 2010, an updated version of 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-like voice), Vivid (bright, cheerful voice), Solid (loud, clear voice), and Light (innocent, heavenly voice).^[23] Crypton Future Media also released Kagamine Rin/Len Append on December 27, 2010.^[24][25]

• Crypton has a "Project if..." with a mysterious, childlike voice.^[31][32][33]
• Crypton has also done some work on a "CV04" with a male voice^[34][35]

According to Crypton, a petition started on Facebook exceeded the needed 39,390 members in November 2010 to join Hatsune Miku's account for an English version to be released; Crypton announced that they were working on an English Miku and was planned to be released in 2013.^[36][37] Hatsune Miku English was released on August 31, 2013.

Piapro

In response to the growing popularity of derivative works created with Hatsune Miku and the other Vocaloid applications, Crypton opened an online community Piapro (stylized as PIAPRO) on December 3, 2007. Vocaloid fans can upload their own content, such as music, art, lyrics, characters, and 3D models to the platform.^[39] "Piapro" stands for peer production and promotes consumer generated media.^[40]

Also under the Piapro brand is Crypton's Piapro Studio, a Vocaloid vocal editor implemented as a VST/AU plugin bundled with all of their full V3 Vocaloid products (Miku V3, Miku V3 English, Miku V3 Bundle, Meiko V3, Kaito V3). This allows for full vocal editing functionality nearly identical in feature support to Yamaha's full Vocaloid 3 Editor software, which is available either as a standalone application or a plugin for Cubase. All Vocaloid 3 voice libraries include the Tiny Vocaloid 3 Editor for free, however this is severely limited in functionality compared to the full V3 editor - serving mainly as a beginner's taste of Vocaloid editing or a way to easily test out a new vocal library. Piapro Studio was created to allow owners of Crypton's V3 products to have a fully featured vocal editor with a modernized and streamlined interface bundled free of charge. It also allows for the loading of 3rd-party, non-Crypton Vocaloid 3 voicebanks - as well as V2's that have been imported into the full V3 editor beforehand. Being a VST plugin, it allows the user to operate entirely within their DAW of choice, in contrast to the tiny or full V3 editors which are standalone applications and the user must export a wav to import into their DAW each time a change or update is needed - or export an updated wav file from their DAW as the background music to import into the V3 editor allowing for convenient editing and a smoother workflow. Currently Piapro Studio lacks some features of the full V3 editor, but most of these are not needed to work with the vocal composition and tuning of the Vocaloid. Crypton however has mentioned they would like to implement something similar to Job Plugins at some point in the future.

Piapro Studio is also regularly updated every few months with new features and bug fixes. Vocaloid 3 Editor updates appear much less frequently, generally only around the time of release of a new Vocaloid. Piapro Studio also features some Piapro social designed singer icons and vocal preview samples, added in an update in the Summer of 2014.
