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.

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.

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.

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. When the piece of music is performed automatically, a tone is generated on the basis of the note information the generation timing of which is corrected on the basis of the information on the timing of generation of that note, while a score is output, the input note information is used as is. As a result, accurate score output is possible with note information input in the real time inputting process, and an automatic performance that is natural and rich in musicality is achieved with note information input by the step time inputting process.
