The column addresses are assigned to the respective instrument kinds such that the certain timbre variations belonging to one instrument kind are registered at the memory locations of one column. The row addresses are divided into a plurality of sections in correspondence to the plurality of the version groups such that the certain timbre variations belonging to one version group are registered at the memory locations specified by the row addresses of one section.
