I read pretty much everywhere that Omnisphere contains *all* the original Atmosphere library -patches and samples included.
Trying to recreate a few of my fave Atmosphere edits, I can't find the Atmosphere source sounds I need in Omnisphere. I'm looking for "Additive Strings" and "Dissonance" for instance, but they're not there in Omni...:-(
ok, I had a helpful contact with Spectrasonics support, and the answer is quite simple:
" Many of the actual Soundsources have been renamed in Omnisphere, so the sounds are there. If you still have access to Atmosphere, you can browse Atmosphere for the particular Layer sound you're looking for. 'Dissonance' is used in the "Hi Tension Wire" patch, so then look up "Hi Tension Wire" in Omnisphere and you'll see the two soundsource names in Omnisphere, "Dissonance" is now "Infinite Flotation"; "Additive Strings" is a layer in " and Violins"; then in Omnisphere it's listed as "Digital Strings"
