I recently got the Omnisphere 2 software as a gift and I did a short video on my YouTube / Exposition tv channel showcasing the quality sounds of their Gospel Choirs.
I have to say, I am really impressed. Besides the vast amounts of instruments, ambience sounds and special effects, The quality alone is worth the price. This is really a musician collectors’ piece of software.
There are sections of individual instruments that sounds very similar to each other and there are some sounds that are better than others but in overall, I really recommend acquiring this software because it does cover the majority of genres out there.
