VOCALOID Keyboard is a powerful, easy-to-use application for aspiring and professional musicians and/or singers. It is designed to help you sing the lyrics to the songs that you care about, so you can enjoy VKB with a new way.

With this application, you can add a new voice – or background singers – to your piece – particularly the ones from “Hatsune Miku”, “Megpoid”, “IA -ARIA ON THE PLANETES-” and “Yukari Yuzuki”. This application is also useful for those who love to sing.

You can change the voice of the singer and the melody by adjusting the parameters, and you can also add the effect of the voice by changing the sound.

The application also allows you to save the settings for your favorite voice to the memory buttons so you can easily switch in between the recordings.
