In a parameter setting system for setting tone characters for producing musical tones in an electronic musical instrument, with respect to a plurality of tone characters having the same values as to a certain parameter, one group is made up with these plural tone characters, and parameters are stored in every group, whereby a required memory size is reduced. Further, respective tone characters are classified into a plurality of groups, and parameter setting and changing operations are executed in every group, whereby these operations are simplified.
