Instead of trying to find 32 professional musicians, why not give Orchestral Strings One a try? This software puts the sound of 14 violins, 10 violas, 8 cellos, and 6 double basses at your fingertips. The modeling technology used by Sound Magic in this software really helps the string ensemble come to life. The overall flow of sound that is so vital to a lifelike string sound is done very well, instead of the single-note sound of some sampling software. The hardware requirements are mild, and it offers Mac and Windows 64-bit support. Give it a try!
