I third Sound Diver XVEdit Pro. I just got the XV- 3080 version (which is actually the same version as the XV-88 version). It's incredibly cool--makes you feel like you're in the cockpit of jet-liner, with a thousand knobs and levers to twiddle. And it does work. And it lets you import SRJV and SRX sound cards, with expandability for new cards as they come out.
Keep in mind that the demo version does not allow you to actually "change" the way the sounds sound--you can fool around with the interface, but it won't transmit the data to your PC.
And it's only U.S. 50 bucks!
