 A single floppy disk can hold 4 "systems", each of which stores 32 patches including all subtractive synthesis parameters and the multisamples used in those patches.The maximum internal sample memory is 256k on a factory standard unit, with some (now rare and hard-to-find) hardware upgrades that increased the memory up to 2MB.A single DSS-1 floppy disk can hold up to 512k worth of multisamples, but only a max of 256k can be loaded into the machine's internal memory.
