I have a brother-in-law who does lots of videos, blogs, and other stuff. He has been looking for the right equipment to do those jobs that he has lined up. Recently I saw mention of something called omnisphere.
I do not know if he is into doing the synthetic type of sounds, but it does sound interesting. He has done some shows and created his own adventure stories that have included many types of sounds and sights. Need to talk to him and find out more.
