Ariana Intro for Kontakt

Soultree Audio's Ariana Singer is a comprehensive vocal sample library for the Kontakt sampler, featuring the voice of Ana Pilat. The free Intro version features some of its features and is completely usable, just with a limited vocal range.
 
However, you can purchase the Ariana and Artenor Intro bundle for a very low price, only 12 € each, and access the full vocal range - almost 3 octaves.
