Hi, just got back from earning a little money doing what I love, music.
One thing that hasn't been mentioned yet is that some of the sounds on the expansion boards are made with internal waves, though not many. So if you download sounds that claim to be from expansion boards, they very well could be. Example, the flutes on the orchestra board are made using internal waves. The orchestra II board has new flute waves, but not the Orchestra I board. Those flutes are just re-tweaked from the original built-in waves of the XP.

For my short bio, I'm a musician by trade, but not full-time yet. I perform live, as well as hire as a session player, producer, and arranger for other local projects. Go to: www.roryhoffman.com
