Re: WHich libraries would fit good with East West Silver XP
With careful editing I believe almost anything.
However, EWQLSO stands out among other orchestral collections due to it's heavy ambience and the fact that it is geared toward film music.
It really depends on what type of music you wish to record.
Your DS Soundware Ulitmate Orchestral Percussion is a great library, I have it also but EWQLSO is better.
The percussion section of EWQLSO is one of the best out there, firstly I would upgrade from silver to at least Gold XP asap. Especially considering the price for you would be about $200 I think.
One of the best buys, if not the best would be KHSO Emerald. For around $350 you get a complete orchestral library that would blend well with what you have. The beauty of Kirks library is it is very playable and sounds great out of the box, easy to edit and such a tremendous value.
My favorite strings are Sonic Implants (now Sonivox) but they require a lot more work than EWQLSO. They are expensive $850 but they are the most beautiful out there by far. For softer romantic scoring and background stuff nothing compares, not even VSL but again, depends on what you want.
Your other string library is good but aging. Get the new KHSO!!
