Emu XL-7 & MP-7 User's Group

I am new to the XL-7.  I will be using it for triggering sequences, 
and covering keyboard and other tones via midi foot pedal in my 
band.  I will also be using it for similar in solo recording 
efforts.  Has anyone been able to get a decent piano tone?  I noticed 
that there really isn't a good stock one.  The raw piano wave doesn't 
sound that great either.  Let me know if you've had any luck creating 
one.
Thanks
