I'm a softsynth fanatic. I've got about 30 or so (most of the big name ones and the more popular freebies).
I've long been aware of Eric Persing's sound creation skill, but for some reason I never had the urge to look into Atmosphere. Perhaps I thought is was 'dated' in the fast changing world of audio software.
I just picked it up and 'Wow!'. The ambient patches are outstanding. I use to use a TG77 for all my ambient patches. Atmosphere doesn't sound exactly like the TG, but some of the patches have the same flavor.
I wish I had bought it sooner.
