Hi, I'll try to give my honest opinion as Opera Singer. I had time to try only the 'legato' patch (and sustain, obviously) and some phrases (that, in general, I think very unuseful).
I'm a tenor (what???)
I'm a transgender woman and I kept my natural voice, since it is part of my art and my work. So; I'll start to write about the tenor legato patch...
The voice is not bad (but not exceptional either), but I don't really like the recording dynamic.
Mf is piano, and 'forte' is not 'forte'; it's something near to 'forte' for the first note you touch (sustain patch), from the second (legato) note it becomes a 'mf' or something less. So, forget to use it in a majestic composition/trailer, unless you don't layer it with a powerful choir. The high notes, are too 'opened', after the 'D' (one of the most common problems of tenor voices), so the 'oh' seem an 'ah', too nasal and 'spoggiata' (I don't know how to translate this italian way to define voices). To let you understand, I can say it seems to listen vocalizes more similar to 'falsetto' than a full voice and the voice is not projected forward. I don't know, maybe someone could like this, but I don't think most people aspect this when buy a 'opera singer' library. Maybe could be great for chamber music
So, No: I don't really like the tenor ah-oh legato patches.
I like the tonal timbre of the soprano voice. Very in tune and I would say with a good technique, but again, I can't understand why to call the two dynamic range 'mf' and 'f', when they are 'p' and 'mf', and there is not near to 'f' in that legato, a part of the first note in some cases.
I'm a great fan of EastWest, but this time I've to say that they need to listen to opera to understand what 'piano' and 'forte' are for a singer. Then, beyond how pleasant and technical the voices can be, it's offensive for opera and opera singer to call a library 'Voice of Opera', just because there are some vibratos and some famous (and unuseful) short famous phrases, when it lacks of a complete dynamic voice range and a 'mf' is presented as an 'f'.
Maybe, the best solution is to use the sustain patch with the script legato, instead of the legato patch (but, ehy... EastWest... for how many libraries we'll need to do this again?).
I think that there is more 'opera' in 'Voices of Passion/The Empire', than here.
Oh... I can forgive them the fact that the damned High C have not been recorded.
It's really a pain in the :emoji_musical_score::emoji_musical_score::emoji_musical_score:
