As I audition the sounds in Omni I always go into the sounds to see how they were created. The new granular page is featured often in the 1.5 sounds.
Check this out:
Call up "Vertigo Rumbler" and go to the edit page then turn off layer A.
Now on layer B you have Elasto Fx menu.
Go into granular and turn it off.
Turn the filter off.
Now you hear more of the raw soundsource.
If you go backward and see what granular is doing it is astounding.
Spectrasonics never ceases to amaze!
