Abstract: An indicator device includes a plurality of light emitters and at least one processor. The processor obtains, at intervals of a first period, a first period maximum value representing a maximum volume among a plurality of pieces of volume information based on an input signal. The processor obtains, for each second period including a plurality of first periods each being the first period, a minimum value among first period maximum values each being the first period maximum value as a second period minimum value and a maximum value among the first period maximum values as a second period maximum value. The processor controls light emission of the light emitters based on a relative ratio of a predetermined first period maximum value among the first period maximum values. The relative ratio is based on the second period minimum value and the second period maximum value.

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 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: Disclosed is an electronic device including: a display; a detector that detects contact or proximity between an operating body and a detection surface; multiple light emitters that are provided at a position corresponding to the detector, and cause the detection surface to emit light; and at least one processor. The processor performs control to link displaying regarding at least part of a content on the display with light emission of at least part of the light emitters.

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.

Abstract: An electronic device includes: a memory including a data region that stores data; a display device; and at least one processor. At least one processor executes: first boot processing in which a boot time is constant irrespective of a usage state of data in the data region, first output processing of outputting information of a first pattern to the display device during execution of the first boot processing, second boot processing in which a boot time varies depending on a usage state of the data, and second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.

Abstract: An electronic device with a dictionary function includes a dictionary data memory, a dictionary search section which makes a dictionary search on the basis of a user operation, a series process storage section which stores data items representing the ones in a series of dictionary search processes performed at the dictionary search section, a detection section which detects an instruction to point in a direction given by a user operation, and a series process reproduction section which reads the series of processed data items stored in the series process storage section in response to the detection of an instruction to point in a specific direction at the detection section and displays a display screen corresponding to each of the processes on a display section.
