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

Hi

I did something to my XL7.  I think it is the preset menu but I don't 
know what I did.  I'll be playing something and it will be nice and 
loud and then it will get quiet then back to loud again.  it repeats 
but isn't a tempo based thing I assume that it is a filter or 
something but I went through and it seems like everything is set up 
correctly.  any suggestions?  

thanks
