The sound is superb, there is zero doubt about that.
That said, I almost wish this library had just focussed on what's new/great about it and left out the "standard" articulations. Specifically I'd like more of these multi-vowel phrases with additional options in the rhythm, tempo, and dynamic departments. I'd buy a library of just those in a heartbeat.
It seems odd to me that there are so many different choices in the actual vowels that fit in to the phrases, but fewer options regarding the differences between the actual phrases. What if I'd like to do something other than pulsing quarter notes with vowel changes on the beat? I've found other developers to have better legatos, sustains and shorts anyway, frankly. Between those other libraries and all of the previous 8dio choirs, I'm definitely covered for now in legatos and shorts so I would have preferred a library super focussed on these arcs with as many choices as possible. But that's just me. I do understand why they're including the gamut of articulations in this.
I am nitpicking, of course, as I appreciate the work 8dio does and the sound is really stellar.
