Anyone considering buying this library should be aware that it still suffers from toothing troubles of the play sample player.
The samples themselves are good, but it does not yet deliver on the legato promise. vocals can sound synth-like and a consistent legato sound is hard to achieve (at the moment).
The gui is ok, very tidy. then again, there's not many parameters that you have control over.
Please also consider that you won't get a very accurate perspective on user response to the product on the developer's forum (sounds-online.com or something), as critical posts are sometimes deleted and threads locked etc.
The Demos of the product are somewhat misleading, as they contain many of the libraries pre-recorded phrases and don't show off the legato patches as much as one would think, considering that's the truly novel thing about this library.
Not saying it's bad or anything, but anyone considering buying it should be very careful that they're really getting what they're hoping for.
Maybe future patches and library updates will fix some of these issues.
