After having some of these type of libraries I don't really find them of great value. Outside of the sung vowels it's like mapping stems to Kontakt. I have plenty of vocal samples that I can dice or run through Melodyne that these type of libraries eventually don't get used. I have one from Soundiron and a bunch from Sonokinetic. I have Realivox Blue, The Ladies, and EW Symphonic Choir which I haven't made use of yet.
There are plenty of great loop libraries out there like ones from Black Octopus. I think there are frees one from Music Radar.
I am tempted to get New Forgotten Voices Francesca for $8. Anyone have that?
