Hello,

kinda new to recording on my MP7, I brought it used and I wanted to 
know if there is a way to delete entire patterns and songs, without 
having to delete tracks one by one? 

I lost a pattern due to the machine stating there was not enough 
space and i need to compress data, it was only at 53% full and after 
it compressed my pattern was gone. 

Anyone can help me with that I would much appreciate some insight. 
thnks
