Description

  The present invention relates to, for example, a musical instrument performance system for performing, composing, learning, and the like based on progression of tonality, mode, chord, and the like, and a technical field of a program that causes a computer to function as such a performance system.

  For keyboard instruments and stringed instruments, the musical sound that is produced by pressing the position of a specific keyboard or string for which the pitch has been determined in advance is selected, and unless the tuning is changed, it is determined by the position at which the keyboard or string is pressed. The pitch cannot be changed while playing. Therefore, along with the change of the music composition sound due to the modulation, etc., the chord holding method and the melody fingering method in the performance change remarkably, and unless you are proficient in musical instrument performance, the music composition sound frequently changes. Music performance is not easy. This makes it difficult for those who are not proficient in musical instruments to intuitively play music whose composition sounds change frequently, and to enhance the understanding of music theory and composition. An example of trying to eliminate the difficulties of such a conventional musical instrument is disclosed in Patent Document 1.

  However, according to the background art system, there is a technical problem that it is still difficult for those who are not proficient with musical instruments to perform along with changes in the music composition sounds of existing musical instruments.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a performance system and a program that can be easily operated even by a person who is not proficient in playing a musical instrument.

<1>
In order to solve the above problems, the performance system of the present invention has a desired combination for use in a performance among a plurality of combinations of a plurality of scales and a plurality of central pitches serving as a reference of the plurality of scales. Mode selection means for selecting as a performance mode, and (i) an input musical sound which is at least one of a unit and a sequence of abstract musical sounds which are musical sounds not depending on the scale or the central pitch. An abstract musical tone input means for inputting by operation or operation input, (ii) an input chord that is at least one of a unit and a sequence of an abstract chord that is a musical tone display that does not depend on the scale or the central pitch; Abstract chord input means for inputting by collective performance operation or collective operation input, and (iii) receiving a performance signal indicating at least one of the input musical tone and the input chord from an external device Accordingly, input means including at least one of performance signal input means for inputting at least one of the input musical sound and the input chord, and at least one of the input musical sound and the input chord input by the input means. And at least one of a unit and a sequence of specific musical sounds output to the outside in accordance with a corresponding function set in advance for the selected performance mode using at least one of the input musical sound and the input chord as input parameters. Performance control means for converting to a certain output musical tone, and generating and outputting a performance signal indicating the converted output musical tone , wherein the mode selection means is assigned one performance mode to each other and arranged on a plane. A plurality of mode selection operators, and an adjacent pair of the plurality of mode selection operators has the one At least one of the scale and the central pitch is to be identical or congruent to each other, the play mode is assigned at.

According to the performance system of the present invention, during the operation, a desired combination of a scale and a central pitch is selected as a performance mode used for performance by the mode selection means. Here, typically, a single combination is selected as a single performance mode. As a selection method, it can be selected immediately by a single operation. It should be noted that the selection can be made in a stepwise manner or in a plurality of sequential operations as in various aspects described later. Prior to the performance, first, a plurality of performance modes that are used or may be used during the performance of the music are immediately selected by the operator during the subsequent performance, for example, on the operation panel or the like. It may be selected to be in a possible state.

  Here, the “center tone” according to the present invention is the first tone of the scale, and the absolute pitch of each component of the scale is determined by determining the absolute pitch. The “central pitch” according to the present invention is one specific pitch, and an interval given from the “scale”, “abstract”, and “corresponding function” is added to the “specific pitch”. In other words, the pitch is a reference pitch when converting “abstract music” into “specific music”. The “performance mode” according to the present invention is a combination of one musical scale and one central pitch, and means a combination of a musical scale and a central pitch that determines the music composition sound.

  The “scale” according to the present invention means that the interval from the lowest sound to the highest sound in which a plurality of sounds having a fixed relative pitch are arranged in order of increasing relative pitch is less than one octave. This means that the interval from the lowest sound to the highest sound with a fixed interval from the first sound of the sound string is less than one octave, in other words, the absolute value of any one sound of the sound string The interval from the lowest tone to the highest tone in which the absolute pitches of all the constituent sounds are determined by determining a specific pitch is a string of less than one octave. The “composed sound of the scale” according to the present invention is a relative pitch included in the scale. The “first note of the scale” according to the present invention is the lowest note of the scale. The “interval” according to the present invention is a pitch difference between two sounds, and means a relative pitch, in other words, a difference between MIDI note numbers of two sounds having a fixed MIDI note number. Specifically, it is a relative pitch viewed from the first note of the scale.

  Since the performance mode is selected in this way, the change in the music composition sound due to the tonality and the progress of the mode can be expressed by the operation of the mode selection means, and the tonality and the progress of the mode and the performance are explained as described below. The correspondence with the operation is clear, and the visibility and intuitiveness of the performance can be enhanced. Further, without changing the abstract musical tone or its chord or its sequence, the output specific musical tone or its chord or its sequence can be changed according to the change of the combination of scale and central pitch by the operation of the mode selection means. .

  The input musical sound is input by at least one of the abstract musical tone input means, the abstract chord input means, and the performance signal input means in the input means in total before or after the operation or operation related to the selection of the performance mode as described above. Or an input chord is input. The input here is real-time input, input while playing, or real-time or non-real-time step input. Here, “real time” means “while playing or during performance time”, and “real time input” means sequential input during performance time.

  The “sequence” that constitutes the input musical tone and input chord according to the present invention means a set of musical tones and chords whose sounding timing is determined, in other words, a musical tone in which note-on and note-off timings and MIDI note numbers are determined. For example, MIDI note number information is replaced with abstract pitch information in a MIDI sequence having one or a plurality of performance channels.

  Subsequently, at least one of the input musical tone and the input chord input by the input means in this way is converted into an output musical tone according to the corresponding function by the performance control means, typically in real time or without delay, and this is indicated. A performance signal is generated and output. Corresponding functions include, for example, a constant indicating a desired performance mode, a constant indicating a desired scale, a constant indicating a desired central pitch, a constant indicating a congruent pitch, and the like. At least one of them is an input parameter (that is, “input variable” or “argument”) and is converted to an output musical tone (that is, the output musical tone is a “return value”).

  More specifically, the “corresponding function” according to the present invention is a function that gives a single interval with a scale as a parameter and an abstract pitch as an argument, and means a function from a set of abstract pitches to a specific set of intervals. In other words, it is a function having a scale as a parameter, a set of abstract intervals as a domain, and a set of specific intervals as a range.

  The “typical definition” of the corresponding function according to the present invention is the union of the set of the constituents of the scale and the whole set of the constituents of the scales obtained by adding or subtracting an interval that is an integral multiple of one octave. The definition of a corresponding function is such that the domain and range are both ordered sets, and the corresponding function is a mapping that maintains the order. For example, the abstract pitch of the domain is the whole integer. And the corresponding function is “when the number of notes in the scale is j, and for any integer a between 1 and j, the abstract pitch a degree includes the a-th note of the scale and the first note of the scale. For any integer k that is less than or equal to 0 and greater than or equal to (j + 1), for an abstract pitch k degree, a number that is greater than or equal to 1 and less than or equal to j can be obtained by adding or subtracting an appropriate multiple of j to k. Interchange corresponding to the abstract pitch k% j degree in the scale when% j It is intended to define the Le a (k- (k% j)) / j * 12 interval added as a function "to correspond.

  The “extended definition” of the corresponding function according to the present invention is a definition of a corresponding function whose range is a set of the whole interval represented by an integral multiple of one semitone. The abstract pitch is a set of whole integers, and the corresponding function is “when j is a constituent sound of the scale, and for any integer a between 1 and j, the abstract pitch a degree includes the first and Interval corresponding to the difference of the a-th sound is associated, and for any integer b between (j + 1) and 12 or less, in the abstract pitch b degrees, the scale among the sounds from the first sound of the scale to its 11 semitones higher sound The interval that is the difference between the bjth lowest sound and the first sound of the scale corresponding to the sound that is not included in the sound and the first sound of the scale is made to correspond to each other. K% 12 is a number between 1 and 12 that can be obtained by adding or subtracting an appropriate multiple of 12. When it is intended to be defined as a function "to correspond to the interval corresponding to the abstract pitch k% 12 ° interval plus (k- (k% 12)) in that scale.

  The “generalized definition” of the corresponding function according to the present invention is a definition of the corresponding function whose range is an arbitrary subset of the entire interval.

  Such a “corresponding function” is (i) preset for the selected performance mode, or (ii) preset for the selected scale and the selected central pitch. Or (iii) a preset pitch with respect to a pitch that is congruent with the selected scale and the selected center pitch. The “corresponding function” may be constructed from the CPU or memory in the form of a conversion table. That is, the “corresponding function” can also be called a “corresponding table”, “conversion table”, “predetermined function”, or the like.

  As described above, the performance signal indicating the output musical sound generated and output by the performance control means in accordance with the corresponding function is typically sent to a voice output device such as an electronic musical instrument or a voice synthesizer and output to the outside. The

  Therefore, it is possible to express changes in music composition sounds due to tonality and mode progression by operating the mode selection means, the correspondence between tonality and mode progression and performance operation is clear, performance visibility and intuition. High nature. Also, specific musical tones that are output in response to changes in the performance mode (ie, changes in the combination of scale and central pitch) by operating the mode selection means without changing the abstract musical tones or their chords, or their or their sequences Or the chord, or the sequence thereof, or the sequence thereof. Here, the `` specific musical sound '' according to the present invention is a musical sound having a pitch obtained by adding an interval given from the `` scale '', `` abstract pitch '' and `` corresponding function '' to the `` central pitch '', In other words, it means that the “musical scale”, “abstract pitch”, and “central pitch” information is converted into “abstract music” according to the corresponding function. Typically, “scale” is a parameter, and “abstract pitch” Is a musical note having a MIDI note number obtained by adding the interval given by the "corresponding function" with the argument to the MIDI note number of the "center pitch", in other words, the abstract tone is embodied and the sound source outputs it It is a musical sound that has all the necessary information. According to the present invention, “the chord (ie, the chord of a specific musical tone)” is a chord of the specific musical tone, and means a set of a plurality of specific musical sounds that are played simultaneously. In other words, the MIDI note number of each constituent tone is determined. It is a specific chord.

  The “sequence of specific musical tones” according to the present invention means a set of specific musical tones whose sounding timing is determined, in other words, a set of musical tones in which note-on and note-off timings and MIDI note numbers are determined. Specifically, it is a normal MIDI sequence having one or a plurality of performance channels.

  The “abstract musical tone” according to the present invention is a musical tone having a single “abstract pitch”, and an interval given from “scale”, “abstract pitch”, and “corresponding function” is set to “central pitch”. In addition, it means a musical tone whose specific pitch is determined for the first time, in other words, a musical note whose MIDI note number is determined only when “scale”, “corresponding function” and “central pitch” are designated. According to the present invention, “the chord (ie, the chord of the abstract musical tone)” is a chord of the abstract musical tone, and means a set of a plurality of abstract musical tones that are played simultaneously. In other words, the scale, the central pitch, the corresponding function, This is an abstract chord in which the pitch of each component of a specific chord is determined only after specifying. The “abstract pitch” according to the present invention is an argument of a “corresponding function” that gives a single interval with the scale as a parameter, and is an abstraction that changes a specific interval according to the scale and the “corresponding function”. It means an interval, in other words, an abstract interval in which a specific interval is determined only when the scale and the “corresponding function” are combined, and is typically an integer.

  As a result, the operator or the player does not need knowledge of how to press chords that change in complex with the change in the music composition, fingering of the melody, and the like. For this reason, even those who cannot play existing keyboard or stringed instruments can easily perform the performance.

As described above, according to the performance system of the present invention, the progress of tonality, mode, chord, etc. can be grasped in a unified manner, it becomes easy to understand visually or intuitively, and the person who is not proficient in playing the musical instrument However, it can be easily operated. Difficult performances associated with changes in the music composition of existing musical instruments are facilitated. In addition, for example, tones that were interpreted as the result of a specific musical performance that was not directly subject to performance operations on existing instruments, or that were in the composer's and performer's thoughts, Changes in music composition sound due to the progress of the mode can be directly subjected to performance operations.

In one aspect of the performance system of the present invention, the performance control means assigns the performance signal indicating the converted output musical tone separately from the abstract musical tone input means, the abstract chord input means, and the performance signal input means. Output via the performance channel.

According to this aspect, the performance signal indicating the output musical tone generated and output by the performance control means in accordance with the corresponding function is sent via the performance channels assigned separately to the abstract musical tone input means, the abstract chord input means and the performance signal input means. Is output. Typically, each performance channel is sent to a voice output device such as an electronic musical instrument or a voice synthesizer and output to the outside. Here, the “performance channel” according to the present invention is a channel for transmitting, processing, or recording a set of musical sounds to be played at the same time or performance information of the sequence without interfering, and is typically a MIDI channel. is there. As a result, the audio output device can output high-quality audio while adopting a relatively simple device configuration and control.
<3>
In another aspect of the performance system of the present invention, the performance control means is such that at least one of the input musical tone and the input chord is at least one of the abstract musical tone input means, the abstract chord input means, and the performance signal input means. The performance signal is generated and output in real time.

In this aspect, when an input musical tone or input chord is input by a performance operation or performance operation through at least one of an abstract musical tone input means, abstract chord input means, and performance signal input means by an operator, performance control means Thus, the input musical tone and the input chord are converted into the output musical tone in real time, and a performance signal is generated and output. Therefore, it can function well as an electronic musical instrument that can output sound in real time or as a part of an electronic musical instrument. Note that “real time” means that the time delay between the operation of the input means and the output of the performance signal is so small that it is hardly or not recognizable on the order of human hearing.
<4>
In another aspect of the performance system of the present invention, (i) the generated and output performance signal, (ii) an audio signal synthesized from the generated and output performance signal, and (iii) the synthesized audio signal Voice output means for outputting at least one of the produced voices is further provided.

According to this aspect, when a performance signal is output from the performance control means, the performance signal is output as-is, amplified, or in a form that can be immediately output by the audio output means. Alternatively, an audio signal synthesized from this performance signal is output. Or the sound produced | generated by the audio | voice signal synthesize | combined in this way is typically output via a speaker. Such output is performed sequentially or in real time to the performance signal generation output. As a result, when an input musical tone or input chord is input by a performance operation or performance operation through at least one of abstract musical tone input means, abstract chord input means and performance signal input means by the operator, the performance control means is Thus, the performance signal, the sound signal, and the sound can be satisfactorily output in real time from the sound output means. In other words, it can function well as an electronic musical instrument that can output sound or the like in real time or as a part of an electronic musical instrument.
<5>
In another aspect of the performance system of the present invention, the mode selection means includes a scale selection means for selecting a desired scale and a central pitch selection means for selecting a desired central pitch.

  According to this aspect, a desired scale is selected by the scale selection means, and a desired central pitch is selected by the central pitch selection means before or after or simultaneously or in parallel therewith. A performance mode is selected as a combination of these selected scales and central pitches. In this case, the corresponding function is set in advance for the selected scale and the selected central pitch, or for the pitch that is congruent with the selected scale and the selected central pitch. Either one of them may be set.

  Here, the “congruent pitch” according to the present invention is two pitches whose pitches coincide with each other if the interval of an integral multiple of one octave is added or subtracted, in other words, The two pitches with the same remainder when dividing the MIDI note number by 12 are the same pitch.

  Note that the “congruent sound set” according to the present invention means two sound sets whose pitch sets match with or without adding an interval of an integral multiple of one octave to any of the constituent sounds. A set of pitches, in other words, a set of two pitches having the same set of remainders obtained by dividing the MIDI note number by 12 is a congruent set of sounds. The “congruent performance mode” according to the present invention is two modes in which a set of constituent sounds becomes a congruent sound set when the scale is taken with the central pitch being the first sound, for example, F-Ridian , C Ionian, G Mixoridian, D Dorian, A Aeolian, E Frizier, and B Locleen are mutually congruent modes.

As a result, the performance mode can be selected by two selection operations or selection operations, ie, selection of the scale and selection of the central pitch by the operator. That is, a performance can be executed after selecting a performance mode by a method that is relatively easy and intuitive to understand. In addition, when the operator or the player designates the mode, the scale and the central pitch can be selected independently, which is convenient when it is desired to proceed to a mode in which only one of the scale and the central pitch is changed.
<6>
Alternatively, in another aspect of the performance system of the present invention, the mode selection means is configured to select one combination as the desired combination as the performance mode by one operation.

  According to this aspect, a desired scale is selected by the scale selection means, and a desired central pitch is selected by the central pitch selection means before or after or simultaneously or in parallel therewith. A performance mode is selected as a combination of these selected scales and central pitches. In this case, the corresponding function is set in advance for the performance mode selected as the combination, or is set in advance for the pitch congruent with the scale and the central pitch of the selected performance mode. Either of them may be used.

As a result, the performance mode can be selected by one operation or one operation of selecting the performance mode by the operator. That is, a performance can be executed after selecting a performance mode by a method that is relatively easy and intuitive to understand. In addition, since a desired performance mode can be selected with a single operation, the mode selection operation can be performed quickly. For example, it is preferable to concentrate on the performance input operation of abstract musical sounds.
In order to solve the above problems, another performance system of the present invention is desired to be used for performance from among a plurality of combinations of a plurality of scales and a plurality of central pitches that serve as a reference for the plurality of scales. Mode selection means for selecting as a performance mode, and (i) an input musical tone that is at least one of a unit and a sequence of abstract musical tones that are independent of the scale or the central pitch. (Ii) An abstract chord input means for inputting by a performance operation or operation input by (ii) an input chord that is at least one unit of an abstract chord and a sequence that is a musical tone display that does not depend on the scale or the central pitch; Abstract chord input means for inputting by manual collective performance operation or collective operation input, and (iii) a performance signal indicating at least one of the input musical tone and the input chord is received from an external device The input means including at least one of performance signal input means for inputting at least one of the input musical sound and the input chord, and at least the input musical sound and the input chord input by the input means One unit of a specific musical tone to be output to the outside and at least one of a sequence in accordance with a corresponding function set in advance for the selected performance mode using at least one of the input musical tone and the input chord as an input parameter And a performance control means for generating and outputting a performance signal indicating the converted output music sound, and the mode selection means is one unit as the desired combination during the performance of the performance system. Can be selected as the performance mode by a single operation by the operator.
According to another performance system of the present invention, during a performance, one combination as a desired combination of the scale and the central pitch is selected as a performance mode by a single operation by the operator. Therefore, the performance can be executed after selecting the performance mode by a method that is relatively easy and intuitively understood.
<7>
In another performance system of the present invention, said mode selection means includes a plurality of mode selection operator one the play mode is assigned to each, prior to the performance, is or used used in the performance The plurality of performance modes that can be assigned may be configured to be assignable to the plurality of mode selection operators by an operation input by an operator including operations of the plurality of mode selection operators. .

According to another performance system of the present invention, the operator selects any one of a plurality of mode selection operators arranged in a plane, for example, arranged at equal intervals in the circumferential direction or one direction. Can be operated. It should be noted that the performance mode may be assigned to each adjacent pair of the plurality of mode selection operators, in other words, to each of the plurality of pairs. In particular, at this time, since the performance modes are assigned so that at least one of the scale and the central pitch in the pair of adjacent mode selection operators is the same or congruent with each other, the desired scale and the desired central pitch are set. A desired performance mode that is a combination of the above can be easily and quickly found. That is, a desired performance mode can be selected easily and quickly.

Moreover, since at least one of the scale, central pitch, and mode is the same or congruent to adjacent mode selection operators, for example, it is desired to proceed to a mode in which the central pitch is changed by fixing the scale. If you want to proceed to a mode with a fixed central pitch and a different scale, or if you want to proceed to a mode in which the scale and central pitch are different but congruent, the destination mode is assigned. Since the operation elements can be adjacent to each other, the mode operation is clear.
<8>
In order to solve the above-described problem, another performance system of the present invention is used for performance from among a plurality of combinations of a plurality of scales and a plurality of central pitches serving as a reference for the plurality of scales. A mode selection means for selecting a desired combination as a performance mode, and (i) an input musical sound that is at least one of a unit and a sequence of abstract musical sounds that are musical sound indications that do not depend on the scale or the central pitch, Abstract musical tone input means for inputting by manual performance operation or operation input; (ii) an input chord that is at least one unit of an abstract chord and a sequence that is a musical tone display that does not depend on the scale or the central pitch Abstract chord input means for inputting by manual collective performance operation or collective operation input, and (iii) a performance signal indicating at least one of the input musical tone and the input chord is received from an external device. Thus, an input means including at least one of performance signal input means for inputting at least one of the input musical sound and the input chord, and the input musical sound and the input chord input by the input means. At least one of the unit and sequence of the specific musical sound to be output to the outside in accordance with a corresponding function preset for the selected performance mode with at least one of the input musical sound and the input chord as input parameters On the other hand, it comprises a performance control means for converting to a certain output musical tone, and generating and outputting a performance signal indicating the converted output musical tone, and the mode selection means is selected from the plurality of combinations as a whole set, First, the first selection means for selecting the subset, and then the performance from the selected subset. Second have a selecting means, said second selecting means for selecting one of the combinations as the play mode are, during playing of the playing system, the one of the combination as the desired combination, by the operator The performance mode can be selected by a single operation.

According to still another performance system of the present invention , a plurality of combinations including a desired combination are first selected from a plurality of combinations by the first selection means, and then the second selection means. The desired combination is selected. More specifically, one or more desired combinations of the scale and the central pitch are selected by the second selection means from the subset selected by the first selection means before or during the performance. The combination is selected as a performance mode by a single operation by the operator. Therefore, the performance can be executed after selecting the performance mode by a method that is relatively easy and intuitively understood. In this case, the corresponding function is set in advance for the performance mode selected as the combination, or is set in advance for the pitch congruent with the scale and the central pitch of the selected performance mode. Either of them may be used.

  Therefore, the performance mode can be selected by two selection operations or selection operations by the operator, that is, continuous or stepwise selection for narrowing down a desired combination. That is, a performance can be executed after selecting a performance mode by a method that is relatively easy and intuitive to understand.

In addition, if there are many combinations of multiple scales and multiple central pitches, and it is difficult to select by one operation, first select the subset from the set of all combinations By doing so, the choices can be reduced, and the mode used for the performance can be selected in the second stage, so that the prospect when selecting the mode can be improved. Typically, a set of modes including a congruent set of modes is selected from all possible scale and center pitch combinations, and then a mode used for performance is selected.
<9>
In a further aspect of the performance system of the present invention, the first selection means includes: (i) a rotary operator for central pitch divided into a natural number of parts in the circumferential direction; and (ii) the central sound. A rotary operator for the musical scale that is arranged on the same rotational axis as the rotary operator for high pitches and is divided into the natural number of parts in the circumferential direction, and the rotary operator for the central pitch and the above At least one of the rotary operators for the musical scale is movable in at least one of the clockwise and counterclockwise directions along the circumferential direction, and the central pitch is transmitted to the rotary operator for the central pitch. At least one part is assigned to at least one part of the natural number, and the scale is assigned to at least one part of the natural number, to the rotary operator for the scale, Rotation operator for the central pitch and rotation operation for the scale (I) the central pitch assigned to each part of the rotary operator for the central pitch, and (ii) the nearest neighbor to each part. By defining the performance mode one by one for each pair, each of the scales assigned to each part of the musical scale rotation operator being a pair, a plurality of performance modes in the certain state are defined. A subset of the performance modes is defined .

  With this configuration, it is possible for the operator to select a subset of performance modes by the first selection means so that both the scale and the central pitch can be easily understood visually or intuitively. It becomes. Therefore, after that, the selection by the second selection means can be executed in a form that can be easily understood visually or intuitively.

Moreover, since the central pitches are arranged on the circumference of the rotary operator, for example, the compatibility with the arrangement of the fifth degree is good. Further, since the mode set is selected by the rotation operation of the rotary operator by the operator or the player, the intuitiveness of the operation is high.
<10>
Alternatively, in the aspect according to the first and second selection means described above, the central pitch rotation operator and the scale rotation operator are each divided into 12 in the circumferential direction, and the central pitch The central pitches are assigned to the rotary operators of the scale in a fifth-degree arrangement, and at least one of seven church rotations or five pentatonic scales is adjacent to the scale rotary operators. When the central pitch is set to the pitch of the first tone of the scale, the set of constituent sounds is assigned so as to be a congruent tone set.

  According to this configuration, the fifth-degree area can be selected quickly and reliably in a form that is easy to understand visually or intuitively by operating the rotary operation element for the central pitch divided into 12 parts. Moreover, it is easy to visually or intuitively understand seven church rotations or five pentatonic musical scales by operating a rotary operator for musical scales divided into twelve in parallel or in parallel with this. Can be selected quickly and reliably.

  Here, the “arrangement of the fifth degree” according to the present invention refers to twelve types of equal temperament in the order of F, C, G, D, A, E, B, F #, C #, G #, D #, A #. Are arranged clockwise or counterclockwise on the circumference. The “clockwise fifth-degree arrangement” according to the present invention refers to twelve sounds of equal temperament in the order of F, C, G, D, A, E, B, F #, C #, G #, D #, A #. Are arranged clockwise on the circumference.

  The “seven church arts” according to the present invention refers to seven of Lydian, Ionian, Mixoridian, Dorian, Aeolian, Frisian, and Rokurien.

  Therefore, it is possible to perform a performance after selecting a performance mode by a method that is relatively easy and intuitive to understand using two coaxially arranged rotary operators.

Moreover, if the arrangement of the fifth degree is clockwise, for example, Lydian, Ionian, Mixoridian, Dorian, Aeolian, Frisian, and Locleen are arranged in this order. Then, since the rotation of the rotary operator by 30 degrees corresponds to the modulation to the genus or the subgenus, the modulation is expressed very clearly visually. For this reason, it also helps understanding the harmony theory and is suitable as a musical educational instrument performance system.
<11>
In this case, the first selection means further includes (i) a central pitch unit divided into a natural number of parts in the circumferential direction in addition to the scale rotary unit and the central pitch rotary unit. A second rotary operator, and (ii) a second rotary operator for the musical scale that is arranged on the same rotational axis as the rotary operator for the central pitch and is divided into the natural number of parts in the circumferential direction. And the second rotary operator for the central pitch and the second rotary operator for the musical scale are each divided into 12 in the circumferential direction, and the rotary operator for the musical scale and the central pitch , The second rotary operator for the scale and the second rotary operator for the central pitch are arranged side by side, and the rotary operator for the scale and the second for the musical scale. The rotary controls are Ionian and Aeolian, or Ionian-derived pentatonic and Aeolian-derived penta The portion to which the tonic is assigned is fixed in a positional relationship that is closest to each other, and the rotation operation element for the central pitch and the second rotation operation element for the central pitch are the central pitch C. And the central pitch A may be fixed in a positional relationship closest to each other.

  If comprised in this way, by operating the rotation operator and 2nd rotation operation elements for the center pitch divided into 12 and operating the rotation operation element and the second rotation operation elements for the scale divided into 12 parts. The desired performance mode can be selected quickly and reliably in a form that is easy to understand visually or intuitively.

  Here, “Lidian, Ionian, Mixoridian, Dorian, Aeolian, Frisian, and Rokurien” according to the present invention is a scale composed of seven constituent sounds, and the interval from the first sound is expressed in semitones. Sometimes the 1st to 7th sounds are Lydian: “0,2,4,6,7,9,11”, Ionian: “0,2,4,5,7,9,11”, Mixolidian: “0,2,4,5,7,9,10”, Dorian: “0,2,3,5,7,9,10”, Aeolian: “0,2,3,5,7,8,10” ”, Frisian:“ 0,1,3,5,7,8,10 ”, Rokurien:“ 0,1,3,5,6,8,10 ”. The “five pentatonic scales” according to the present invention refers to five of an ironian-derived pentatonic, a mixorian-derived pentatonic, a durian-derived pentatonic, an aeolian-derived pentatonic, and a friesian-derived pentatonic. The “ionian-derived pentatonic, mixorian-derived pentatonic, dorian-derived pentatonic, aeolian-derived pentatonic, and friesian-derived pentatonic” according to the present invention is a scale composed of five constituent sounds, and the interval from the first sound is a semitone. When expressed in units, the 1st to 5th sounds are Ionian-derived pentatonic: “0,2,4,7,9”, mixolydian-derived pentatonic: “0,2,5,7,9”, durian-derived Pentatonic: “0,2,5,7,10”, Aeolian-derived pentatonic: “0,3,5,7,10”, Frisian-derived pentatonic: “0,3,5,8,10” is there.

Therefore, it is possible to perform a performance after selecting a performance mode by a method that is relatively easy and intuitive to understand using two pairs of rotary operators. In addition, a set of congruent modes created by a pair of scale rotary operators and a central pitch rotary operator, and a congruent mode created by a pair of scale second rotary operators and a central pitch second rotary operator. Since it is always possible to be adjacent to each other, it is easy to proceed to a congruent mode.
<12>
In another aspect of the performance system of the present invention, at least one of the abstract musical tone input means and the abstract chord input means is provided on the mode selection means.

According to this aspect, the operator performs an operation related to the input of a musical tone or a chord with the abstract musical tone input unit or the abstract chord input unit provided thereon while performing the operation related to the selection with the mode selection unit. As a result, the operability is greatly improved as a whole. In addition, since the mode selection operation and the performance operation of the abstract musical tone or the abstract chord can be performed at a close position, the combined performance operation of both is facilitated.
<13>
In another aspect of the performance system of the present invention, the mode selection means designates a pitch that is congruent with the central pitch as the central pitch used for the performance, depending on which one of the operators has operated. A plurality of mode selection operators are provided for each of the central pitches.

  According to this aspect, by operating a plurality of mode selection operators, a pitch congruent with the central pitch can be designated as the central pitch used for performance. Therefore, a desired performance mode can be selected by an operation that is relatively simple or reliable and less likely to cause mistakes.

In particular, when the performer performs the mode selection operation, not only the mode is selected, but also the pitch that is the same as the central pitch can be specified as the central pitch used for performance, so efficient performance operation is possible. For example, when a central pitch rotation operator that employs a fifth degree arrangement is used as the mode selection means, even in a fifth degree arrangement in which only 12 types of non-congruent pitches can be arranged, the mode selection operation is performed. The octave of the central pitch can also be changed. Therefore, it is possible to overcome the shortage of central pitch options used for performance.
<14>
In another aspect of the performance system of the present invention, the mode selection means shares an operation member with at least one of the abstract musical tone input means and the abstract chord input means.

According to this aspect, for example, the mode selection means including operation members such as a touch panel, operation buttons, operation keys, and operation dials includes the abstract tone input means and the abstract chord input means, Share members. For this reason, the range of responsibility operated by the operator can be reduced. For example, a performance mode can be selected by hand operation within a relatively small space range or plane range such as a range that can be reached with both hands, a range that can be reached with one hand, or a finger in one hand. Convenient. In particular, not only the mode is selected by the player's mode selection operation, but also an abstract musical tone or abstract chord is played and input, which is suitable for playing an abstract musical tone or abstract chord as the mode progresses.
<15>
In another aspect of the performance system of the present invention, the input means includes the abstract chord input means,
The performance control means converts the abstract chord input by the abstract chord input means into a chord of a specific musical tone that has been automatically voiced.

  According to this aspect, when a unit or sequence of an abstract chord is input as an input chord by the abstract chord input means in a desired performance mode, the performance control means automatically performs voicing. As a result, the input musical tone is converted into a chord of a specific musical tone. Here, “voicing” according to the present invention refers to converting a specific chord into one of arbitrary chords that can be obtained by adding or subtracting an interval that is an integral multiple of one octave to some constituent sounds. It is.

Therefore, an output musical sound with voicing can be obtained according to the input operation, which is very convenient in practice. In particular, the performance system can automatically perform chord voicing in a number of ways. For example, chord performances with appropriate open voicing or closed voicing according to the range of notes can be performed using abstract chord input means. It can be done simply by operating, and can assist the performance of players who are not familiar with chord voicing and performance.
<16>
In another aspect of the performance system of the present invention, the input means further includes a rhythm sequence input means for inputting a rhythm sequence independent of the scale and the central pitch by manual performance operation or operation input. The performance control means includes the performance signal indicating the converted output musical tone, and the performance signal assigned to the abstract musical tone input means, the abstract chord input means, the performance signal input means, and the rhythm sequence input means. The performance control means stores the rhythm sequence input by the rhythm sequence input means, and the performance signal of each musical sound constituting the stored rhythm sequence is output through the channel. Output at sounding and mute timing.

  According to this aspect, in addition to the input of musical tones and chords, a rhythm sequence is input by the rhythm sequence input means by one or a batch performance operation or one or a batch operation input. Here, the “rhythm sequence” according to the present invention is a set of sounds whose sounding timing is determined and not affected by the scale and the central pitch, and is typically a percussion instrument performance sequence. When the rhythm sequence is input in this way, the performance control means assigns the performance signal indicating the converted output musical tone separately to the abstract music input means, abstract chord input means, performance signal input means and rhythm sequence input means. Is output via the performance channel. At this time, in particular, in the performance control means, first, a rhythm sequence is stored, and then a performance signal of each musical tone constituting the stored rhythm sequence is output at the timing of sounding and muting of each musical tone. .

As a result, even a rhythm sequence can be performed by a performance operation or operation input in the input means, so that a variety of performances are possible. In particular, since a percussion instrument sequence can be input and output to the performance system, a variety of musical expressions that combine rhythm, melody, and harmony can be achieved with the performance system alone.
<17>
In another aspect of the performance system of the present invention, the performance system further includes performance status display means whose display status changes according to at least part of the selection status by the mode selection means and the input status by the input means.

According to this aspect, during performance, for example, an LCD (Liquid Display Device), an EL (Electro-Luminescence Device) device, an LED (Light Emitting Diode), depending on the selection status by the mode selection means and the input status by the input means. In the performance status display means including various display devices such as devices, lights, lamps, mirror ball lighting devices and lighting devices, for example, display color, light intensity, lighting state, flashing state, item shape to be displayed Various display states are changed. Therefore, it is possible to construct an environment in which an operator or a viewer can easily understand the performance situation visually or an attractive environment. In particular, since the performance status can be visualized, for example, the active mode and the abstract musical tone being played can be easily understood visually, and the performance of the performer can be assisted.
<18>
In another aspect of the performance system of the present invention, the performance system further includes setting input means for setting at least one of parameters defining characteristics in the mode selection means, the input means, and the performance control means by an external input operation. To do.

  According to this aspect, at least one of the parameters defining the characteristics of the mode selection means, the input means, and the performance control means is set by the external input operation by the setting input means prior to or during the performance. Then, various operations in each means are executed in accordance with parameters that define the newly set (in other words, updated) characteristics.

  Here, the “parameters that define the characteristics” according to the present invention include, for example, a scale assigned to each part of the rotary operator for the scale, a central pitch assigned to each part of the rotary operator for the central pitch, and a corresponding function. Constants, voicing method when outputting specific chords, tone and volume of each performance channel, playback tempo of abstract musical tone or abstract chord sequence, whether to play abstract musical tone or small and medium chord sequences in a loop, and performance status display Display method of the means, reflection timing to the output musical tone at the time of mode update by the mode selection means, abstract pitch assigned to each abstract music performance operator, abstract chord assigned to each abstract chord performance operator, pitch offset of each performance channel, For example, a method for converting a performance signal input from an external device into an abstract pitch.

As described above, since the response and response to operations and inputs in the performance system can be changed with a wide range of flexibility and relatively easily, it is very convenient for performing a desired performance. In particular, the detailed operation settings of the performance system can be changed by the operator or the player, and in particular, the player can freely set the scale, central pitch and corresponding function to be assigned to the operator. Performance using any scale, not limited to pentatonic, becomes possible.
<19>
In another aspect of the performance system of the present invention, the abstract musical sound input means inputs the input musical sound, which is the sequence of the abstract musical sounds, by at least one of real-time input and step input by manual performance operation or operation input. The abstract chord input means can input the input chord as the sequence of the abstract chords by at least one of real-time input and step input by manual batch performance operation or batch operation input. The performance signal input means can input at least one of an input musical tone that is the sequence of the abstract musical tones and an input chord that is the sequence of the abstract chords by at least one of real-time input and step input. The performance control means is (i) input by the input means. Sequence storage means for storing the input musical tone and the input chord as an input sequence; and (ii) sequence conversion for converting the stored input sequence into the output musical tone that is the sequence of the specific musical tone according to the corresponding function. And (iii) sequence output means for outputting the performance signal indicating the converted output musical tone at the timing of sounding and muting of the converted output musical tone with reference to the time in the timer.

  According to this aspect, in the input means, input musical sounds and input chords are input in real time or step input as a sequence. Thereafter, the input musical tones and chords input in this way are first stored in the sequence storage means by the sequence storage means as an input sequence in the performance control means. Thereafter, the input sequence stored in this way is converted into an output musical tone which is a sequence of specific musical tones by the sequence conversion means. Thereafter, the performance signal indicating the converted output musical tone is converted by the sequence output means on the basis of the time in the timer which is the internal timer or the external timer (for example, based on the timing signal or clock signal from the timer). The output tone is output at the timing of sounding and muting.

In this way, it is possible to construct an environment in which a sequence constituting an input musical tone or an input chord is input relatively easily, and a sequence constituting an output musical tone is output at an appropriate timing after the conversion. Therefore, it becomes very convenient when using a sequence exclusively for performance. In addition, the abstract musical sound sequence read from the sequence storage means can be read and converted in accordance with the change of the combination of the scale and the central pitch by the operation of the mode selection means without changing the abstract musical sound or its sequence. Then, the specific musical sound and its sequence can be changed. This eliminates the need for the operator or performer to know how to hold chords that change in a complex manner depending on the tonality, and how to finger the melody.
<20>
In another aspect of the performance system of the present invention, in addition to or in place of the input means, the performance system further comprises sound storage means for storing at least one of the input musical tone and the input chord, In addition to or instead of at least one of the inputted input tone and input chord, at least one of the stored input tone and input chord is read from the storage means and converted into the output tone.

According to this aspect, for example, the input musical tone or input chord stored in advance in the sound storage means such as a semiconductor memory device, a hard disk device, or an optical disk device in advance before the performance or sequentially stored during the performance is the performance control means. Are read from the sound storage means and converted into output musical sounds. Accordingly, not only real-time performance but also operation input for performance can be performed in advance, and processing including various processing by the performance control means can be executed at any time after storage. Alternatively, a performance in which a part of the sound is stored in advance and the other part of the sound is operated and input in real time is possible, and the range of how to use the performance system is widened.
<21>

  FIG. 4 is a flowchart showing the operation of this embodiment. 4, in the initialization step (S100), the CPU 230 reads out the control program 260 from the ROM 210 to the RAM 220 and executes it, and the abstract musical tone performance operators 150-q (q = 1, 2,..., Q), and Abstract pitch assigned to MIDI note number of MIDI signal input, abstract chord assigned to each abstract chord performance operator 180-r (r = 1, 2,..., R), scale rotary operator 110 and central pitch Reads and inputs the scale and center pitch assigned to the rotary controller 120, the corresponding function, the voicing method, the initial value of each scale, the color assigned to each center pitch, and the initial value of the pitch offset of each performance channel The scale rotation operation detection circuit 115 and the central pitch rotation operation detection circuit 125 of the unit 100 are accessed to access the scale rotation operation element 110 and the central pitch rotation operation element 12. Of detecting the initial state is written in the RAM220 the direction of the scale and the central pitch at 12 as an initial active mode. The performance controller 200 sends a control signal to the LED drive circuit 365 and assigns it to the scale rotary operator 110 and the central pitch rotary operator 120 by the LED 360-1 (l = 1, 2,..., L). The name of the assigned scale and the name of the central pitch are displayed, and the portion to which the active scale and the central pitch are assigned is lit in the color assigned to the active scale. Further, the CPU 230 activates a touch panel display control program in the control program 260. When the initialization step (S100) is completed, the performance system executes steps S110, S140, S145, S200, and S220 in parallel.

  In step S110, when the performance control apparatus 200 receives operation information from the musical scale rotation operation detection circuit 115, the central pitch rotation operation detection circuit 125 or the mode selection operation detection circuit 135, the CPU 230 performs the musical scale rotation operation detection circuit 115. And the central pitch rotation operation detecting circuit 125 are accessed to obtain the position information of the scale rotary operation element 110 and the central pitch rotation operation element 120, and the CPU 230 writes the position information into the RAM 220 (step S120). The CPU 230 writes the mode in the RAM 220, and the CPU 230 transmits an active mode update signal to the LED drive circuit 365 (step S130). At this time, the mode selection operator 130-n (n = 1, 2,...) Operated by the operator's manual operation or operation input on the musical scale rotary operator 110 or the central pitch rotary operator 120. , N), if any one of the scale and the central pitch is not assigned, the CPU 230 maintains the active mode (in this embodiment, the control program 260 uses the above-mentioned 12 values as the initial state). And 12 central pitches are assigned to the scale rotary operator 110 and the central pitch rotary operator 120, and are assigned by the operator operating the setting operation program using the touch panel display 140 by an operation input. Can also be canceled). In step S135, the CPU 230 accesses the RAM 220, refers to the output history of the musical sound, transmits the note-off signal of the specific musical sound in the output history to the output unit 300, and the CPU 230 causes the CPU 220 to extract the abstract pitch recorded in the output history. In the updated new active mode, the CPU 230 converts the sound into a new specific musical tone by a mechanism described later, and the CPU 230 sends the note-on signal to the output unit 300. The CPU 230 outputs the note-on signal in the output history on the RAM 220. The MIDI note number pair of the abstract pitch and the specific musical tone in the state is rewritten to the pair of the MIDI note number of the abstract pitch and the new specific musical tone.

  In step S140, if the CPU 230 receives a performance operation signal transmitted from the abstract musical tone performance operation detection circuit 155 or a MIDI event transmitted from the MIDI signal input detection circuit 165, if it is a note-on signal, the CPU 230 causes the RAM 220 to The active mode is read and the active mode is read, and the MIDI note number of the specific musical tone is obtained from the active mode and the abstract pitch obtained by referring to the conversion table on the RAM 220 from the operation information received by the CPU 230 or the MIDI event note number. Is calculated by the CPU 230 (step S150), and the CPU 230 refers to the output history on the RAM 220. If the MIDI note number is not in the output history of the performance channel corresponding to the input means, the CPU 230 A note-on MIDI event of a body music sound is transmitted to the output unit 300 (step S160), and the performance control apparatus 200 outputs an output history of a performance channel corresponding to a pair of an abstract pitch of a note-on target and a MIDI note number of a specific music sound according to the input means. Is stored in the RAM 220 (step S170). On the other hand, if the signal received by the performance control device 200 is a note-off signal, the CPU 230 refers to the conversion table on the RAM 220 and performs the performance corresponding to the input means stored in the RAM 220 with the abstract pitch obtained from the received signal. The CPU 230 obtains the MIDI note number of the specific musical tone of the pair of abstract pitches by referring to the output history of the channel (step S150), and the CPU 230 refers to the output history on the RAM 220 and if this MIDI note number is in the output history. The note-off signal of the MIDI note number of the specific musical tone of the pair of abstract pitches is transmitted to the output unit 300 (step S160), and the information of this pair is deleted from the output history of the performance channel corresponding to the input means (step S170). .

  In step S145, when the performance control apparatus 200 receives a performance operation signal from the abstract chord performance operation detection circuit 185, if it is a note-on signal, the CPU 230 accesses the RAM 220 and reads the active mode. The abstract chord assigned to the operated abstract chord performance operator 180-r (r = 1, 2,..., R) is read from the RAM 220, and each abstract pitch of the abstract chord is specified according to the corresponding function. The MIDI note number of the musical tone is calculated by the mechanism described later (step S155), and the performance control device 200 performs voicing of the specific chord according to the mechanism described later according to the voicing method input by the operator manually or by the mechanism described later by the operation input. For each constituent sound of a specific chord, the CPU 230 uses the RAM 22 If the MIDI note number is not in the output history of the specific chord performance channel with reference to the output history above, the CPU 230 sends a note-on MIDI event of the specific musical note MIDI note number to the output unit 300 (step S165). The control device 200 stores a pair of abstract pitches of note-on targets and MIDI note numbers of specific musical sounds in the RAM 220 as an output history (step S175).

  On the other hand, if the signal received by the performance control device 200 is a note-off signal, each abstract pitch of the abstract chord obtained from the received signal by a mechanism described later is referred to the output history stored in the RAM 220 and each abstract The MIDI note number of the specific musical tone of the pitch pair is obtained (step S155), and the note-off signal of the MIDI note number of the specific musical tone of each abstract pitch pair is transmitted to the output unit 300 (step S165). The information of each pair is deleted (step S175).

  Here, the “voicing method” according to the present embodiment will be described in detail. Here, a mechanism will be described in which an operator designates a voicing method manually or by operation input, and the performance control apparatus 200 performs voicing of a specific chord. In the present embodiment, the operator activates the setting operation program using the touch panel display 140 by an operation input, in which the operator selects a chord voicing method by “close voicing”, “open voicing”, “ If the operator selects “No change” and the operator selects something other than “No change” by an operation input, the operator also determines whether the chord reference pitch will be the central pitch or a specific specific pitch. Is selected by the operation input, and when the operator selects the latter by the operation input, the operator selects a more specific pitch by the operation input, and the CPU 230 writes the result in the RAM 220. When “close voicing” is designated as the voicing method by the operator's operation input, the performance control device 200 changes the pitch of the specific chord from the pitch that is 5 semitones lower than the chord reference pitch to its 11 semitone higher pitch. An interval that is an integral multiple of one octave is added to or subtracted from a sound having a pitch outside the range so that the chord is output. When “open voicing” is designated as the voicing method by the operator's operation input, the performance control device 200 is within the range from the 11 semitone lower pitch of the chord reference pitch in the active mode to the 23 semitone higher pitch. For all possible chord arrangements using the above pitches, an index m, which will be described later, is calculated, and the one with the smallest index m is adopted as the output chord. The index m is the square of the difference between 24 / (w-1) when the number of chord constituent sounds is w and the interval between the sounds that occur when the chord constituent sounds are arranged in pitch order. , The sum of w−1 intervals between adjacent sounds. When “no change” is designated as the voicing method by the operator's operation input, the performance control device 200 employs the original specific chord as a chord that is output as it is.

  In step S200, the operator operates the touch panel display 140 by an operation input to operate the abstract sequence editing program, the abstract sequence operation input, the abstract sequence read from the storage device 240, and the abstract using the control program 260. When any operation of automatic sequence generation is performed, the CPU 230 updates the abstract sequence on the RAM 220 (step S210).

  Here, the “mechanism for inputting an abstract sequence using the touch panel display 140” according to the present embodiment will be described in detail. Here, a mechanism in which an operator inputs an abstract sequence using an operation input using the touch panel display 140 and a method for expressing the abstract sequence will be described. In order for an operator to input an abstract sequence using the touch panel display 140 by an operation input, the control program 260 includes an abstract sequence editing program therein, which is used instead of a MIDI note number by an operator input. This is a sequence editor for inputting abstract pitches. Therefore, the embodiment only needs to follow a normal MIDI sequence editor, and the only difference is that an operator inputs by operation input is an abstract pitch instead of the MIDI note number of the MIDI event. At this time, since the definition range of the MIDI note number is 0 to 127, in this embodiment, the definition range of the abstract pitch is limited to -60 to 67, and the number obtained by adding 60 to the abstract pitch is written as the MIDI note number. Adopt a format.

  In this embodiment, in the initial setting, the performance control apparatus 200 processes the MIDI event number transmitted from the MIDI signal input detection circuit 165 minus 60 as the abstract pitch of the abstract musical sound. Similarly, when the CPU 230 writes the abstract sequence on the RAM 220 to the storage device 240, a file format is used in which the number obtained by adding 60 to the abstract pitch is stored as the MIDI note number of the MIDI event in the standard MIDI file format. Conversely, when the CPU 230 reads the abstract sequence from the storage device 240 into the RAM 220, the CPU 230 reads the number obtained by subtracting 60 from the MIDI note number of the standard MIDI file as the abstract pitch of the abstract musical sound. The rhythm sequence is expressed as a normal MIDI sequence. Therefore, the input mechanism also conforms to a normal MIDI sequence.

  In step S220, the performance control device 200 executes step S230 and subsequent steps when the timing of note-on or note-off of the musical tone that constitutes the abstract sequence or the musical tone that constitutes the rhythm sequence is reached. In step S230, if the performance control apparatus 200 is a note-on signal with respect to the abstract musical sound constituting the abstract sequence, the CPU 230 accesses the RAM 220 to read the active mode, and the CPU 230 reads the corresponding function from the active mode and the abstract pitch. According to the above, the MIDI note number of the specific musical tone is calculated by the mechanism described later (step S230), and the CPU 230 refers to the output history on the RAM 220 and if the MIDI note number is not in the output history of the performance channel of the abstract sequence, the CPU 230 A note-on MIDI event of a musical tone is transmitted to the output unit 300 (step S240), and the CPU 230 uses the abstract pitch of the note-on target and the MIDI note number pair of the specific musical tone as an output history of the performance channel corresponding to the input means. To save (step S250). On the other hand, if it is a note-off signal, the CPU 230 refers to the conversion table on the RAM 220 and refers to the output history of the performance channel corresponding to the input means stored in the RAM 220 for the abstract pitch obtained from the received signal. The CPU 230 obtains the MIDI note number of the specific musical tone of the pair of abstract pitches (step S230), and the CPU 230 refers to the output history on the RAM 220 and if this MIDI note number is in the output history, the specific musical tone number of the pair of abstract pitches. A note-off signal with a MIDI note number is transmitted to the output unit 300 (step S240), and this pair information is erased from the output history of the performance channel corresponding to the input means (step S250). For the rhythm sequence tone, the CPU 230 transmits the MIDI event to the output unit 300 as it is. In the present embodiment, the operator can input a setting from the touch panel display 140 manually or by an operation input as to whether or not the sequence is played back in a loop.

  Next, the “mode selection mechanism” according to the present embodiment will be described in detail. Here, a mechanism will be described in which the operator selects a mode that is a combination of a scale and a central pitch used for performance by manual or operation input. When the operator manually rotates the musical scale rotary operator 110 or the central pitch rotary operator 120, the musical scale rotary operation detection circuit 115 and the central pitch rotational operation detection circuit 125 detect this operation and perform the performance. Operation information is transmitted to the control device 200, and the performance control device 200 records the latest state of each rotary operator in the RAM 220. There are always twelve combinations of scales and central pitches in the positional relationship on the scale rotary operator 110 and the central pitch rotary operator 120 facing each other, and this is the mode set in this embodiment.

  That is, in this embodiment, there are twelve types of scales and central pitches, and there are 144 modes in total. However, the operator manually operates the scale scale rotary operator 110 or the central pitch rotary operator 120. 12 mode sets are determined for each of the 12 possible positional relationships between the scale rotary operator 110 and the central pitch rotary operator 120. Here, the operator operates one of the mode selection operators 130-n (n = 1, 2,..., N) manually or by operation input (that is, selects one mode from the mode set). The mode selection operation detection circuit 135 transmits the operation information to the performance control device 200, and the performance control device 200 updates the latest state of each rotary operator recorded in the RAM 220 and the scale assigned to each. Based on the information on the central pitch, the mode selection operator operated by the operator manually or by operation input, the adjacent scale on each rotary operator, and the central pitch are recorded in the RAM 220 as active. That is, the operator activates one mode from the mode set by operating one of the mode selection operators 130-n (n = 1, 2,..., N) manually or by operation input. Choose as a thing.

  Next, the “conversion mechanism” according to the present embodiment will be described in detail. Here, a description will be given of a mechanism in which the performance control device 200 converts an abstract musical tone constituting at least one of an abstract musical tone, an abstract chord, and an abstract sequence into a specific musical tone. The performance control device 200 includes an abstract pitch of each abstract musical tone constituting an abstract musical tone, an abstract chord, and an abstract sequence, an active musical scale and a central pitch stored in the RAM 220, and an abstract musical pitch defined by a corresponding function. The CPU 230 calculates a specific pitch of each specific musical tone, that is, a specific MIDI note number, based on the correspondence relationship between the specific musical tone and the interval, and sets it as the pitch of the specific musical tone output from the performance control device 200. Specifically, the performance control apparatus 200 sets z + (k− (k%), where k is the abstract pitch of the abstract musical tone, sc is the scale, j is the number of constituent notes of the scale, and z is the MIDI note number of the central pitch. j)) / j * 12 + f (k% j, sc) is the MIDI note number of the specific musical sound. Here, k% j indicates a number from 1 to j that can be obtained by adding or subtracting an appropriate multiple of n to k, f is a typical definition of the corresponding function, and f (x, y) is determined by the corresponding function. The interval corresponding to the abstract interval x and scale y. Furthermore, if an offset of a non-zero pitch is set due to an initial value or an operator input to the touch panel display 140 to change by a setting operation program, the CPU 230 further adds a pitch to the MIDI note number of a specific musical tone. Add the offset. Here, if the pitch of the specific musical sound finally calculated by the CPU 230 is less than 0 or 128 or more, it is not defined as a MIDI note number, so the CPU 230 ignores the specific musical sound and outputs it. do not do.

  Next, the “sequence automatic generation mechanism” according to the present embodiment will be described in detail. Here, a mechanism in which the performance control apparatus 200 automatically generates an abstract sequence will be described. For the automatic generation of the abstract sequence, the performance control device 200 automatically generates a MIDI sequence using an existing arbitrary automatic melody generation algorithm, and the performance control device 200 calculates the number obtained by subtracting 60 from the MIDI note number of the MIDI sequence. Although an abstract sequence may be used as an abstract sequence, in this embodiment, the performance control device 200 randomly selects one of integers from −6 to 8 and uses it as an abstract pitch of one abstract musical sound. And an abstract sequence that automatically generates a one-bar sequence in which 16 abstract musical tones produced by this method are arranged.

  Next, the “recording mechanism” according to the present embodiment will be described in detail. Here, a mechanism in which the performance control apparatus 200 records an abstract sequence will be described. The performance control device 200 receives the operation information of the operator or the MIDI event note number transmitted from the abstract musical tone performance operation detection circuit 135, the abstract chord performance operation detection circuit 185, and the MIDI signal input detection circuit 165 to the performance control device 200. Is converted into an abstract pitch by referring to the conversion table on the RAM 220, and the input to the RAM 220 for each input means using the abstract pitch of each musical tone and the timing of the performance operation or MIDI signal input given by the timer 270. Save as an abstract sequence with two performance channels.

As mentioned above, although embodiment of this invention was described, this invention can have other embodiment. For example, it is as follows.

Specify the active center pitch to be written by adding or subtracting an integer multiple of one octave to the center pitch depending on which of the multiple controls is operated manually or by the operator. You may be able to do it. For example, in the first embodiment, as shown in FIG. 5 having the same meaning as in FIG. 2, two mode selection operators are provided for each central pitch, and the operator selects the outer peripheral mode selection operation manually or through an operation input. When the child is operated, the CPU 230 writes, in the RAM 220, a pitch that is higher than the active central pitch and closest to the active central pitch. When the inner peripheral side operation element is operated manually or by operation input, the CPU 230 has a pitch that is lower than the active central pitch and closest to the active central pitch. May be written to the RAM 220. In this embodiment, the scale rotary operator 110 and the central pitch rotary operator 120 are divided into 12 parts, and each mode has two mode selection operators, so N = 24. . Other configurations and processes are the same as those in the first embodiment.

If the positional relationship as shown in FIG. 5 is always fixed, a mode similar to the active mode is always located at a short distance of the active central pitch, and the performance operation becomes more comfortable. In this embodiment, the behavior when the second mode selection operator 131-n (n = 1, 2,..., N) is operated is the mode selection operator 130-n (n = 1, 2,...). , N), and the other configuration and processing are the same as those in the first embodiment.

The pitch may be written in the RAM 220 as active. In this case, the scale rotation operator 110 is an example of the “scale selection means” in the “mode selection means” according to the present invention, and the central pitch rotation operator 120 is the “mode selection means” according to the present invention. It is an example of “central pitch selection means”.

[4] Embodiment in which “one-shot selection” is possible The mode input may be performed so that it can be selected manually or by a single operation by the operator. For example, in the first embodiment, instead of the scale rotary operator 110 and the central pitch rotary operator 120, as shown in FIG. 7 or FIG. Operators 130-n (n = 1, 2,..., N) are arranged side by side, a specific mode is assigned to each of them, and an operator selects a mode selection operator 130-n (n = When 1, 2,..., N) are operated, the performance control device 200 may write the mode assigned to the operated operator as the active mode in the RAM 220. Further, the shape and arrangement of the mode selection operators 130-n (n = 1, 2,..., N) are not limited to those in which square or hexagonal operators are arranged in a grid pattern, The method of selecting the mode to be assigned is not limited to that shown in FIGS.

That is, an abstract musical tone performance operator 150-q (q = 1, 2,..., Q) provided in each part on the musical scale rotary operator 110 or each of the central pitch rotary operators 120. The abstract chord performance operator 180-r (r = 1, 2,..., R) provided in the portion may also serve as the “mode selection means” according to the present invention.
[6] Embodiment in which “mode selection unit also serves as abstract chord input unit” The mode selection unit may serve as at least one of an abstract musical tone input unit and an abstract chord input unit. For example, in the first embodiment, when the operator operates the mode selection operator 130-n (n = 1, 2,..., N) manually or by operation input, the mode selection operation detection circuit 135 performs performance control. When the operator operates the abstract chord performance operator 180-r (r = 1, 2,..., R) manually or by operation input, the abstract chord input operation detection circuit 185 performs performance control on the apparatus 200.
