At the time of writing, the link in the description is wrong - it takes you to Violin Textures, which is a different library, and cheaper than the Viola Textures library.
I have been a fan of Emergence audio libraries since the launch of their first instrument and have purchased all except the Infinite piano as I don’t yet have Kontakt 7. As you demonstrated the textures of the Viola library are 0:20 superb as are the other string libraries and the choirs. Currently working on A Fantasy on Faure’s Pavane which includes performances with Viola and the choirs…will let you know when Impost it.
