In an electronic musical instrument, a complete range of a keyboard can be split into at least two registers, so that a different kind of tone color can be assigned to each of two registers. The electronic musical instrument provides at least four tone-color designating switches, one edit switch and two kinds of indicators. Each of the four tone-color designating switches is capable of independently designating a certain tone color. Herein, two tone-color designating switches are provided to designate two tone colors respectively for use in one register, while other two tone-color designating switches are provided to designate two tone colors respectively for use in another register. The edit switch designates each of parameters which are used to define a property of the tone color. The first indicator indicates the tone color currently designated, while the second indicator indicates the parameter currently edited. Thus, the production of the musical tones using at least one of the two tone colors can be designated with respect to each of the two registers.
