Vowel sounds with Etna

Creating vowel sounds with 3 band-pass filters involves simulating the resonant frequencies (formants) that characterize different vowels. Each vowel sound can be approximated by adjusting the center frequencies, bandwidths, and gains of these filters.
With Etna, you can craft compelling vowel sounds using its morphing capability.

Is the Etna officially released? All shops in europe say "pre-order". Thank you, I'm looking forward to buying this module.
