I don't actually disagree (and said as much in an earlier post).
I do disagree here. I totally understand the comment, though; I used to think the same. But I A/B'ed 'em extensively. ...Omnisphere is every bit as good, quality-wise, if you pick the right filters. Diva is more ... immediately good, perhaps, I admit. It's hard to make Diva sound bad. Omnisphere is easier to screw up. Yup. But it's worth the price with the extra features. For modulation alone, it would be worth it. But it also comes with a bajillion effects, a bajillion patches, top-notch wavetables, AND a huge ROM sound set to mix in. Totally worth it. It's Diva times 8. ...and uses a third of the CPU.Omnisphere may have a good synth engine, but it can't compete with DIVA in that aspect.
(Note: if you had said *RePro* has a better-sounding engine... I would agree with you. RePro actually sounds like hardware. It's amazing.)
Don't get me wrong! I love (!!!) Diva. And, yes, I agree it's a better starting synth: less overwhelming, less expensive, less of a risk.
Just had to defend Omnisphere a bit. It certainly has its haters, and I'm not sure it fair.
