i have an original BOSS DR-550 drum machine. i know some folks have been able to upgrade their older versions to the Mark II but i can't seem to find out how to go about doing this. any leads/help would be grand. Thanks in advance.
 
check out the boss site i think its www.bossus.com , im not sure.They have some customer #'s for percussion stuff, you could call and find out.
