The VSO ExpansionPack adds a variety of instruments to the "Solo" category of the Vienna Smart Orchestra. The instruments are available separately to be played as lead instruments, either in "Pad + Solo" mode (for adding melodies with your right hand while ensemble accompaniments are played with your left hand), or in "Full Range Mode" to play solo instruments in their natural ranges.
The expansion to Vienna Smart Orchestra introduces the following new instruments and articulations:
Legato Strings: Viola Ensemble and Cello Ensemble
Legato Woodwinds: Piccolo, English Horn, Bass Clarinet, Bassoon
Single Notes: Harp, Celesta, Timpani
Instantiating the expanded Vienna Smart Orchestra on several tracks, you can even create complex polyphonic string arrangements. Enrich your compositions by adding lyrical woodwind solos in several new colors or create a variety of combinations, e.g., clarinet + bassoon, or flute + piccolo in unison or octaves.
As with the string and wind instruments, the harp and the celesta can be used in combination with the accompanying orchestra or as individual instruments with their full range of six octaves and four and a half octaves, respectively. The timpani provides a high level of detail with eight velocity layers from ppp to fff and four variants per note and velocity layer.
