Musical sound data groups are recorded in nonvolatile memory banks by multiplexing the data without being compressed. A data reader reads the musical sound data in parallel from the plurality of nonvolatile memory banks according to reading instructions from an access module. In a musical sound generation system that cannot expect which pitch of the musical sound data is instructed to be read, since a plurality of pieces of data can be read in parallel from the plurality of nonvolatile memory banks, a sound production delay time can fall within an allowable time. Thus, by using a currently dominant large-capacity multi level NAND flash memory as a memory for the musical sound data, a high sound quality and compact musical sound generation system can be realized.
