AquesTone 2 – Free Vocal Synthesizer Released By AQUEST

AquesTone 2 by AQUEST.

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.

The website is in Japanese, so I’ve provided a Google Translate version of the download page in the download section below. Here’s the link to the original AquesTone 2 download page.

Basically, what you’re getting here is probably finest freeware vocal synthesizer out there. It is your free ticket to Vocaloid style vocals, provided that you’re using a Windows based DAW. Although I’ve never used AquesTone in a finished tune, I use it for sketching vocal tracks all the time and it’s a fantastic tool for that purpose.

Please note that there’s a note on the product 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.

UPDATE: Our reader arkmabat contacted the developers and they told him that the new version of the plugin will be released once the old one expires.

ENGLISH MANUAL: Our reader kechi2dtm has provided an unofficial English version of the manual on his website: AquesTone 2 Manual (English)

  1. well…I always into vocal synthesizing. especially to vocaloid and [utau]. I even make FL Chan singing to my song.
    I wonder if it’s gonna be commercial product or not.

  2. Brilliant; and you’re the first site with news again. Keep it up man! Version 1 is of my favorite plugins.

    • Hmm, it doesn’t work here in FL Studio 10 :(

      The funny thing is that i have the first version, which is only a dll file.
      There are many files and libraries in the download file.

    Say, chaps! While you’re at it, would you mind translating the manual and all other info as well? The formants or, better, phonetics are all Japanese too, but I don’t expect you’ll have time to sing in some proper English ones into the library file, will you?


  4. What a nice synth!
    Anyone figured out how to load .syl files yet?
    And how do I get the rough robotic sound linke in the youtube clip? It sound much smoother here.

  5. To clear up the confusion, I sent an email to the company:


    Hi, Arkmabat

    > Can I use the free version if the music that I make is free to download?

    You are kindly requested to put “AquesTone” in the credit title.

    > Will AquesTone2 stop working/functioning in May 2016?

    Yes. but then we will release a extend the period version.
