You know, it's been widely debated which sample lib is the best and all that but personally I like and find value in all of my libs. Sometimes I use a lot of EWQLSO Gold Pro Xp, sometimes the VSL samples from Kontakt 2, and more recently I've been really getting into the Miroslav Philarmonik lib. Great sounds that inspire great ideas. I'm just glad I have these various sounds to use. Sometimes switching libraries allows me to think differently about composing. I've had a boat load of ideas using the Philharmonik combi patches. Are they as realistic as EWQL or VSL? Probably not. But they inspire ideas and that's really what it's all about.
I just ordered Garritan's Strad 2 to add to my virtual orchestra and I'm really jazzed (pun intended) about working on some upcoming projects using J&BB.
Perhaps it's just the season but I'm thankful to be able to afford having and using all of the wonderful sounds.
