Best Service Extended Classical Choir Keyswitched KONTAKT | 407 MB
This is a custom crafted version of the choir library, heavily modified to be more useful in a modern sampler like Kontakt. It's an old library (very hard to find now, too) but extremely useful because it has consonants sampled individually (such as T, P, K, and Tzz) as well as uncommon singable consonants (such as Mmmm, Rrrr, and Zzzz). It is best used to "punch up" your favorite choir by overlaying syllables and consonants to help enunciate whatever your choir is already singing. The flexibility of this library to create any word you want is pretty good, just add your own reverb to blend it in with your choir library of choice.
