Solo Strings II offers 46 GB of all-new articulations of the four solo string instruments. Solo Strings II contains many of the playing techniques that the first collection includes, but played "con sordino" (with mutes). It includes articulations such as muted short and long notes, crescendo and diminuendo variations, as well as Interval Performances such as legato, portamento, and trills. Furthermore, additional Legato Performances with very long notes have been recorded for use in slower parts. Thus, every single pitch and velocity is available in 24 variations.

Like all Vienna Instruments collections, Solo Strings II is a sample-based virtual instrument that ships in the formats VST (OS X, Win XP/Vista), RTAS (OS X) as well as AU (OS X) and also works stand-alone.
