I have played some .mid files now, but I have not noticed any problems 
with my Audigy 2.

When I downloaded the fonts file, mine had a different name to yours.
Yours: WST25FStein_00Aug14.SF2
Mine: WST25FStein_00Sep22.SF2

Can you provide me with a .mid file that shows the problems and is easy 
to reproduce the problems?

Cheers
James
