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 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 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 effect providing apparatus is provided which ostensibly increases the number of effects that can be simultaneously provided. When switching to flanger processing is performed while filter processing in accordance with a periodic signal (LFO signal) is being performed in an effect processing section that can provide only one effect, a CPU advances the periodic signal (LFO signal) from a phase at the time of the switching, and performs the filter processing in accordance with the advancing periodic signal when the flanger processing is ended. As a result of this configuration, the number of effects that can be simultaneously provided is ostensibly increased.
