I use this to do the string sections of my songs - I'll rarely use it to do more than that, as the brass leaves much to be desired, but the percussion and woodwinds are okay. Once i get a better processor, I might upgrade to something better, but right now it gets the job done.
Along with the Sonatina Symphonic Orchestra soundfont, this is what I use with my orchestral sounds. Still saving up for Eastwest libraries, but this is pretty good for now.
This is a good set of orchestral samples pulled from the Roland JV1080, but they will require some EQing to get a brighter sound. Great for starters, but when compared to East West and Kontakt libraries, it is lacking in quality and realism.
