An improvement over the MOTIF XS is the use of non-volatile flash memory for samples and sample libraries. Instead of DIMM memory modules, the XF uses proprietary flash cards. While more expensive than DIMM modules, the flash cards can permanently store sample data. The volatile DIMM modules in previous models could not store data when the unit powered off. Once initially loaded into the XF, the user doesn't have to reload sample data every time they power up the keyboard. The MOTIF XF is also the first in the MOTIF series since the MOTIF Classic to have standard internal SDRAM for sampling built into the keyboard.
