iVOCALOID was released initially as a portable version of the VOCALOID2 software released for the iPad.
This mimics the VOCALOID3 engine (originally VOCALOID2). It provides a limited number of voices and can only use a single track of data, offering just 17 bars of measure. It can use VOCALOID NET. Its range is limited to C3~F4.
YAMAHA announced a version of the VOCALOID™ software for the iPhone and iPad, which was exhibited at the Y2 Autumn 2010 Digital Content Expo in Japan. It uses a version of the VOCALOID2 engine.
December 2010, VY1 was released for the software. While this version has limited capabilities, the price of ¥1,800 for the iPad has made this the second cheapest version of the VOCALOID™ software on sale. Currently, this version of the software has only been released in Japanese. Those wishing to purchase this software must also have a Japanese chip on their iPad or iPhone to use it.
October 2011, VY2 was also made available on iPhone and iPod touch in the iTunes store.
November 2012, Aoki Lapis was added. This makes her the first VOCALOID3 voicebank to later be released on a version of VOCALOID2.
April 2014, Merli was added. This version later claimed no.1 for all music app sales in the Japanese iTunes store.
