I am looking for advice on the best VI or library of synth-based sounds that are more soundscape -- not big complex hits that draw too much attention, but something that you can bend (as in pitch bend / twist / modify) or curl around an orchestral piece to make it dark and threatening. Something like some of the darker Distorted Reality noises. Definitely don't want "classic" synth sounds like Jupiters or something in that vein.
Hope this is clear -- can't wait to hear what you come up with. I am on an Intel Mac quad and have external PCs running XP -- no Vista so far.
