I have erased ALL my song(copied empty sequnce into there places)
erased mostly all my patterns and i am getting 57% of my memory 
used...also i got like a wierd crash today and it asked me to 
compress the memory so i did..whats going on here? There is hardly 
anything in there and it says the memory is used up..Is there any way 
to do a factory re intit or something..or am i freakin out for 
nothin...
