Here is the release version of An Orchestra Strings using the VSCO2 Community samples. It has a complete String Section, Solo Violin, Violin Section, Viola Section, Cello Section, Solo Contrabass and Harp. In various nkis it can do legato, modwheel xfades, fake ensembles and fake round robins. It generally has 2 velocity layers, the shorts tend to have 2 round robins and there are samples about every three notes. Articulations include Arco Vibrato, Tremolo, Spiccato and Pizzicato.
The most unique thing are the three An Orchestra nkis using the string section for arps and chords.
