AQUEST has released AquesTone 2, an improved version of their freeware vocal synthesizer VSTi plugin for Windows.
AquesTone2 AquesTone2 is a software-based synthesizer vocal. It supports VSTi plug-in, you will be able to easily generate the singing voice information from the text and lyrics MIDI.
AquesTone 2 is available for free download via AQUEST (216kB download size, 32-bit VST plugin format for Windows).
The website is in Japanese, so I’ve provided a Google Translate version of the download page. Here’s the link to the original AquesTone 2 download page.
Please note that there’s a note on the download page, which says that the link will expire in May 2013. I’m not sure if the plugin will go commercial, or that they will simply release an improved freeware version in May.
