I just received my Kirk Hunter Virtuoso Strings and they are absolutely fantastic! They seem to be the warmest, richest sounding strings I've heard. There's one patch called 24esp that covers the entire keyboard and is perfect for grabbing some quick chords (which is how I compose) The sound is very full, lush and warm. There's also some nice chamber strings and a ton of articulations with different velocity settings etc.
Keep in mind that this library was produced when 32 megs (not gigs!) were all a sampler could handle. I just finished up a piece of music for an animation i did using EWQL's Gold and the Virtuoso Strings and am very happy with the results.
I don't work for Kirk Hunter, I just feel that he has captured the sound of strings that I have been looking for for a long time and wanted to share this discovery with you all.
Oh, and for $49 it's an absolute steal.
All the very best,
