PURPOSE:To facilitate the musical performance and the number of control elements by providing a means for selecting a parameter changing means for changing a predetermined musical note parameter in accordance with an output from a pitch bend control element or a pitch control means. CONSTITUTION:There is provided a midpoint return type pitch bend control element 20 which may be of any one of a wheel type, a lever type and a joy- stick type and delivers data in accordance with a performed value thereof. The output data may be used either for operation for changing a music note parameter or for operation for adjusting the musical note pitches. A change-over means 21 selects either one of the operations. With this arrangement, it is possible to reduce the number of control elements and to efficiently set a parameter with the use of the control element 20. |
