Ok. So I've had a few months to sit on this and develop an opinion. I'm going to just go ahead and start with the cons... no need to sugarcoat it.
The installation process is very complicated. The software that comes in the box isn't even up to date, so you have to go online and install an update patch as soon as you are done installing the discs. The other drawback is that you have to use an iLok to open the program. iLok recently updated their license managing app, and the new app gave me problems after I installed it so I haven't been able to open the program. East West is not particularly known for their customer service either, so all in all, this has been a huge headache.
• Frustrating to install, update, use
• iLok required
When the program worked it was really cool. The word builder was the main attraction for me and it was really neat, but the rest of it (consonant and vowel sounds, etc.) is pretty much on par with some other choir samples. The choir samples that come with Logic are just as good in my opinion, and they don't require an iLok.
• Word Builder is really neat
• Samples are good (even if only on par with other programs)
I mostly use choir and orchestra as a backdrop for songs, so I don't really do any full-on scoring for movies or gaming. If you have the time and patience to really dedicate to using East West programs to their fullest ability for film and game scores, have to have word builder, don't mind dealing with the hassles of iLok and license managing/updating software and really sketchy customer service from East West then this might be for you. Otherwise, look elsewhere.
I bought this and the East West Orchestra Silver edition on sale, and regret it. If you are on a Mac platform, look into Logic. It's cheaper, comes with a lot of good choir and orchestra plugins (but no word builder), and doesn't require an iLok. Winning combination if you ask me.
Final verdict: Not worth it.
