I have been trying to use arp patterns in some tracks.  I have been 
having troubles getting it to work out quite right.  Sometimes it 
won't play the pattern at all.  Sometimes it will, but If I try to 
copy it to another location, it won't work, or If I power down, and 
then back up it won't work.  

      Anyways, I would like to hear yall veteran cats tips about 
sequencing with arps...

        Thanks
