Necessity is a motha!
But I need some glue, my main orchestral libraries thus far are quite dry (VSL bits that came with Kontakt and KH Diamond, CS2, and CB2). Generally speaking I like them because they are dry, and I can mold them into lots of different shapes, but something is still missing. I've added CineOrch to projects and it's really made a difference, so I'm going to give OE a try. It was down to that or the Spitfire stuff, and this was an easier (read less expensive) way to get my feet wet with ambient sample libraries. And I like the sound a lot!
Alchemy - that has become my go-to synthesizer over the last year or so. It can do so many cool things, and it works really well in orchestral settings.
Morphestra, and Project Alpha, and a couple others that spring to mind would be great additions for the sound part of the sound track, or at least that's how I think I'd use them<G>!
So many libraries... so little cash!
