How To Achieve A Sound As In The Following Tracks?

Hello all :)
I have a considerable problem with achieving a proper sound in my work. I'm aiming to tweak a part as in the following:
1) http://www.youtube.com/watch?v=ZBZtSwoBsng - from the very beginning, then in the background up to about 2:00
2) http://express-ec.native-instruments.com/fileadmin/ni_media/producer/kontaktsoundpack/THE_GIANT/audio/Elysian_Fields.mp3 - here, a few first seconds from this demo from Native Instruments

I intend to keep my target track in this style. In the first case, it seems to me that it's a specific way of extracting sounds from the strings so it's a conventional selection of instruments.
As it is in the second audio, most likely it's a digital library of sounds so if anybody knows the name of that VST and know exactly how to achieve it...
Thanks in advance 4 your help and greet y'all :)
