Yes, I recently got Omnisphere, but so far it's not made it into any of my songs. It doesn't "feel" like other VST synths. It seems more about sample morphing and less about synthesis, so it's got a much longer (and more customized) learning curve, at least for me. I'm still trying to wrap my head around an Omnisphere workflow/creative process. It's obviously hugely powerful. I'm just not (yet) getting how it all hangs together.
Thanks for the tip on Zebra3. Zebra looks much more like the usual analog modeling synths I've been using (Massive, z3ta+2, etc.), so I think I could probably get it into my productions pretty quickly, once I do buy it. I love the look of the modular patch creation page.
As far as your "Vermillion Road" soundtrack, yeah, I think the song could easily have gone on a bit longer to let it develop some more.
