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 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 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 electronic musical instrument includes at least one function operator associated with at least one process, and at least one processor, wherein the at least one processor executes the followings, deciding that musical performance is being performed or not in response to an operation to the at least one function operator, in response to deciding that the musical performance is being performed, executing the at least one process associated with the at least one function operator, and in response to deciding that the musical performance is not being performed, not executing the process associated with the at least one function operator, despite being operated to the at least one function operator.

Abstract: A DSP subtracts the sound pressure Pgen of a notification sound from the sound pressure Pout of an octave band including the notification sound among the sound pressures P1 to P8 of octave bands having center frequencies f1 to f8 acquired by the octave analysis of ambient noises including the notification sound, and thereby acquires the octave band characteristics of only the ambient noises. Next, the DSP detects the sound pressure Pmin of an octave band of the ambient noises which has the lowest sound pressure and the sound pressure Pmax of an octave band of the ambient noises which has the highest sound pressure from these octave band characteristics. Then, the DSP generates an output waveform of the sound pressure Pgen that is almost equal to the sound pressure Pmax of the octave band having the highest sound pressure in the octave band having the lowest sound pressure.

Abstract: A CPU sets an application of music sound generation to each of plural ports, and a priority to the set application, and further sets the maximum number of channels that assign an arbitrary sound source to each port from plural kinds of sound sources and produce sounds. When a new sound generation request is supplied to a certain port in which all sound generation channels of the port are currently generating sounds, and when the sound generation channels to be used for the sound generation are in short, the CPU supplies the sound generation request to a channel not producing a sound currently in other port to which the application of the same priority is set.

Abstract: In an automatic performance device which automatically performs a piece of music composed of note information input externally, note information input on a real time basis is corrected on the basis of beat information of a piece of music input thereafter and the resulting note information is stored. Correction information for converting the corrected note information into the originally input uncorrected note information is also stored for each note information. When the piece of music is performed automatically, a tone is generated on the basis of the corrected note information and the correcting information, but when the piece of music is output as a score, output is made on the basis of the corrected note information. Alternatively, for note information input by a step time inputting process, information is stored on a timing at which each note input thereafter is generated.
