Abstract: An electronic musical instrument includes an operation receiver that receives an input operation and a processor. The operation receiver includes a rotating wheel. The rotating wheel includes a first light emitter that emits colored light. The processor causes, upon the rotating wheel receiving an input operation, the first light emitter to change an emission color from a color at a start of the input operation to a color corresponding to a rotation angle of the rotating wheel having received the input operation.

Abstract: An electronic musical instrument includes an input device that receives an input operation, a display, and a processor. The processor performs a first process upon duration of a detected continuation of the input operation being a reference time or longer. The processor performs a second process upon duration of a detected continuation of the input operation being less than the reference time. The processor causes the display to display a content from which it is determinable whether or not duration of a detected continuation of the input operation being the reference time or longer.

Abstract: An input interface device includes at least one processor. The processor performs control to cause, among light emitters, a first light emitter corresponding to a contact/proximity point detected by a detector to emit light with a luminous intensity higher than that of a remaining light emitter. The contact/proximity point is where an object is in contact with or in proximity to a detection surface. The processor further performs control, while the object is moving along the light emitters in a state in which the object is in contact with or in proximity to the detection surface, to gradually reduce a luminous intensity of, among the light emitters, a second light emitter corresponding to a point where the object being in contact with or in proximity to the detection surface once detected by the detector is no longer detected to put out the second light emitter in a predetermined time.
