Just bought Ultimate - mainly for Piano Colours, Mysterio and the Light Collection tbh - but am interested in some better orchestral sounds that those that come with Kontakt 7 factory. So I have:
Emotive Strings
Action Strings 2
Session Strings 2
Symphony Essentials (various)
Session Horns Pro
Stradivari Violin
I don't have space to install them all and guess there is a lot of overlap - more interested in playable instruments (with the keyboard) than phrases so that may rule out Emotive Strings and not sure I really care about having a Strad, but otherwise I have too many options. What's the diff between them?
