AQUEST has released
Vocalizer,
a free vowel effect VST effect plug-in for Windows

voice characteristics to any input sounds. Vocalizer
can be used not only for lead sounds but also for
various sound sources.

- Strongly apply human voice characteristics.
- Intuitive GUI control with XY-pad (Strength
of effect, Vowels can be controlled with X-Y pad
only).
