I have the expansion for the eight outs for the MPC and I want to know if I should do it myslef or take it in. I also want to know what kind of memory I should put in to expand my sampling capabliites. Is it the same as computers? A couple of people have pointed me in the wrong direction and I really want to push my MPC to the exreme. I know I could get this type of info by Googling or something like that but I want to get good info from people who have dealt with this type of equipment personally.
