I used a SW60xg (the old EISA card) together with a Powersampler (Scope Home) and that was a good combination.
I think you should be able to use the soundmodule from sw1000, but no guarantee
I used a audiocable from sw60xg to my Powersampler, and this might be the way to do it for you too, even if SW1000xg is a different card.
On the other hand, Yamaha rarely update drivers,.
I use a Yamaha MU15 - witch is a outboard SW60sx so to speak, and its very handy for general midi.
