East West Symphonic Orchestra and Sonivox DVI Brass are the VST i'm speaking of
Hey, I'm guessing you want to trigger at the same time?
I use EWSO also and when I want to build something bigger or mix something that the presets dont offer, I use an app called Energy XT which is actually a Mini DAW but comes with a VST that allows you to load as many synths as you like and control them simultaneously. You also have mixing and effect options too. Its cheap too.
