Ah, if that Roland Brass Section Soundfont is the one I'm thinking of, it is indeed a good one. It took me a while to find a decent-sounding Brass Section.
I have two requests: First, can anyone recommend a good Orchestra Hit Soundfont? Preferrably one that sounds natural (i.e., like an actual orchestra, not the more filtered/artificial ones)? Second, Saxophones. All of the Soundfont ones I've found suck... real bad. Any recommendations?
Oh, and as an aside, I highly recommend Extreme Sample Converter to anyone who works with Soundfonts. Lets you easily preview each instrument in all of your Soundfonts, and you can even export individual instruments as their own SF2 files, or export individual samples as WAVs. It works with lots of other sample formats, too.
