A plural tone selector for an electronic musical instrument comprises first and second latching selectors each having a plurality of input terminals supplied with tone signals of different pitches, a plurality of control terminals corresponding to the input terminals and one common output terminal. A plurality of key switches are provided for causing one of the plural control terminals of the first and second latching selectors respectively to be impressed with control voltage to selectively derive from the common output terminals of the first and second latching selectors two tone signals supplied to the input terminals thereof corresponding to the control terminals upon the selective actuation of the key switches due to key depression. The derived tone signals are supplied to first and second sustain keyers, respectively, which are conducted by control voltage impressed by other key switches actuated upon key depression.
