hi. im actually so confused right now. i am pretty much a n00b at all terminology. so basically all i know is that i want a program that makes it sound realistic when i press play in sibelius 5. i dont know anything about "sequencers" or "sample librarys" or basically what its called. however i am interested in this EWQLSO gold play edition thingo. would i be buying the right thing if i bought this program? help please! im so confused...
