Getting the original sound of this clip with Garritans seems impossible. This is the best I could do.
http://www.takutogame.com/Images2/Or...l_Quartet4.mp3 - Same clip as the latter, but with a bit more layering of ensembles.
http://www.takutogame.com/Images2/QuartetTest2.mp3 - There are 2 Violins, 2 Violas, 2 Celli, and 2 Basses in this clip. Violin #1, Viola #1, Cello #1 and Bass #1 have legato portamento set on them. Whenever there is a small interval I try to add in the portamento.
The Cello is doubled with an very round analog synth that bends.
The Original Clip:
Garritan should release a String Quartet sample library. :-)
