mpc memory

Hey what up.....where can i purchase the memory expansion card....can i get it at best-buy or somethin....or do i have to order it....and i'm havin problems using midi with the mpc and my computer.....was there a disk that was supposed to come with the mpc so i can communicate thru midi....i'm trying to use it with fl studio

Comp Usa has them.....16mbs or 32mbs I have one stick of 32mbs in my mpc2kxl or you can check on ebay......If I were you I'd go for a single stick of 32mb 72 pin 70ns stick of ram for it it just works out better. Sometimes the cheaper ram will and can cause problems
