@Kalti: I know that some English vocals have the [R] phoneme that can produce the sound I think you're looking for. I'm not sure if Cyva has it but many of the Zero-G vocals do. See English Phonetics A couple years ago I did a similar test using repeated "ru"s for Luka (along with Rin and SeeU) to immitate this sound. https://soundcloud.com/meerkatqueen/rollingrtest
