I've owned Omnisphere for like 10 years, and although I did upgrade to version 2.0, I've toyed around with it but never used it much, because it offers a little TOO much. It sounds fantastic, but it's kind of a swiss-army knife, and the same aspects that put me off of workstations are exactly the same reason I rarely reach for Omnisphere. I enjoy the "individualism" of hardware instruments, and finding ways to work their limitations, sound profile and personality into the musical process. I never really wanted a mega-synth that does everything, because the idea is less musically inspiring to me somehow.
Hardware integration is one of those things I've been meaning to try (it was one of the big features of version 2), but only got around to trying it today.
Well...I'm SUPER impressed! It works as advertised, and honestly if more soft synths did this, I might use them more. I tried it with the Prophet 6 and Rev 2 profiles. For example, when I selected FX on the P6, it modified the FX rack in Omnisphere and replaced existing rack FX with the Omnisphere equivalent, and on the Rev2 when using the Modulation buttons and controls to map destinations, all of the modulations were setup correctly (in real time) in the mod matrix in Omnisphere.
Great job by Spectrasonics! Given the flexibility and sample/synthesis possibilities of Omnisphere, it's kind of like turning one of your existing synths into a ProphetX or Quantum (assuming you already use a DAW anyway).
Here is a complete list of the supported hardware synths (quite a good showing for Sequential):
