ABSTRACT:
A musical tone generating apparatus is provided that generates a musical tone of a selected one of tone colors that is defined by a combination of a first kind of number and a second kind of number. An operating element used for setting a tone color and having an incrementing function and a decrementing function is operated to set at least the second kind of number by using at least one of the incrementing function and decrementing function. A memory device stores a list in which the tone colors to be selected are listed, the list having a first axis having a plurality of locations to which a plurality of first kind of numbers are respectively assigned, and a second axis having a plurality of locations to which a plurality of second kind of numbers are respectively assigned, each of the first kind of numbers having a basic tone color assigned thereto, each of the second kind of numbers having an extended tone color that is a variation of the basic tone color of a corresponding one of the first kind of numbers. Each time the operating element is operated, one of the second kind of numbers that is assigned to a currently selected tone color is changed to a number of the second kind assigned to a tone color that is different from the currently selected tone color and is present next to the currently selected tone color in the list.
