[Prior art]
[Patent Document 1] JP-A-2001-022354
A performance means having an arpeggio generation function of generating an arpeggio (dispersed chord) in response to an operation of a predetermined performance operator by a user (for example, a key press operation of a keyboard or the like) is commonly called an “arranger”. Conventionally known arpeggiators store at least a plurality of key numbers (not a note number (pitch information) corresponding to a pitch, but a simple number) corresponding to an arpeggio pattern and a sounding timing for each key number. . In the case where a plurality of keys are simultaneously pressed by the user, the arpeggiator sets a predetermined rule (for example, in ascending order of pitch) with respect to a note number assigned to each of the plurality of simultaneously pressed keys. Etc.). Then, an arpeggio is generated based on a key-pressed sound by generating a note number to which a number corresponding to a key number in the stored arpeggio pattern is assigned at a sounding timing corresponding to the key number. .
[0003]
In the above-described ordinary arpeggiator, the tone of the chromatic tone (for example, piano tone) is set on the sound source device side, so that the output of the arpeggiator is output as a dispersed chord, By fixedly assigning the tone of the drum set to (note), it becomes possible to output a predetermined drum sound in response to a key depression operation of the corresponding key by the user. For example, for the notes “C3”, “E3”, “G5”, “A5”, “B5”, and “C6”, drum sounds such as bass drum, snare drum, rotam, hi-tom, hi-hat close, hi-hat open, etc. Is assigned, and a drum sound corresponding to a note number corresponding to the predetermined note generated according to a key pressing operation by the user based on the data can be generated. In this way, the arpeggiator can also be used as a drum pattern generator (this is particularly called a fixed note type arpeggiator).
[0004]
[Problems to be solved by the invention]
By the way, the above-described conventionally known arpeggio generation device has a problem that an arpeggio having an unnatural hearing is generated depending on the number of simultaneously operated performance operators (for example, the number of keys pressed). there were. For example, in the case of an arpeggiator that generates an arpeggio based on an arpeggio pattern defined so that the sounding timings come in descending order of key numbers, when the user presses only one key, the key is assigned to the pressed key. The pitch is not easily pronounced. If the number of simultaneously operated keys is smaller than the number of key numbers defined in the arpeggio pattern, there is an arpeggiator that generates a predetermined substitute sound for the insufficient key number. In this case, a complicated arpeggio is generated even though the number of keypresses operated at the same time is small, which is contrary to the user's request that a simpler arpeggio be generated as the number of keypresses decreases. However, it is not convenient.

[0017]
Here, arpeggio pattern data stored in the ROM 2, the RAM 3, the external storage device 7, or the like will be described. FIG. 2 is a conceptual diagram showing one embodiment of the data structure of the arpeggio pattern data. FIG. 2A shows the overall structure of the arpeggio pattern data, and FIG. 2B shows an embodiment of the sounding pattern data included in each type of arpeggio pattern data.
[0018]
The arpeggio pattern data is data including one or more pieces of sounding pattern data (described in detail later) that define the sounding timing, tone length, volume, or octave shift of the pitch of each of the arpeggio constituent sounds, and are preset data or user data. These are data prepared for a plurality of types, such as those set by. That is, as shown in FIG. 2A, the arpeggio pattern data is stored for each type (for example, musical instrument type such as piano and drum), and the arpeggio pattern data for each type is stored in accordance with the number of keys pressed. One or more sound pattern data is included.
[0019]
As shown in FIG. 2B, the tone generation pattern data is a single tone composed of five elements: timing (Gate), gate time (Gate), key number (Key), octave shift (Oct), and velocity (Vel). This is data that stores the data for one bar for one bar. The timing (Timing) is data representing a clock value corresponding to a tone generation start timing of a musical tone, and the gate time (Gate) is data representing a time length (clock numerical value) from key-on to key-off of a musical tone to be produced. The length of the sounding pattern data is one measure (1920 clocks). In this embodiment, according to the described timing values, when the number of keys pressed is 1, a quarter note (1st and 3rd beats) is used. When the gate time 480) is the number of key presses 2 to 4, the data is data that constitutes an arpeggio pattern that produces quarter notes for each beat.
[0020]
The key number (Key) is data for determining the pitch of a musical tone when producing an arpeggio. That is, a register corresponding to this key number is set in the RAM 3 in advance, and a note number detected in accordance with a key press operation of each key in the arpeggio key range is stored in the register. Assign a note number to. Then, in the arpeggio generation processing, the note number assigned to the key number in the sounding pattern data is read out from the register, and the note number is determined as the note number that determines the pitch of the musical tone that produces the note number. Note that this note number does not always become the pitch of the musical tone itself, since there are processes such as octave shift. For example, if the number of key presses that can be detected according to the key press operation of each key in the arpeggio key range is set to four, the key number is a numerical value of 1 to 4, and the value of this key number is the pitch change of the arpeggio. It is assigned in advance for each data of one sound corresponding to the pattern.
[0021]
Octave shift (Oct) is data that specifies how many octaves to change when the pitch (note) indicated by depressing each key in the arpeggio key range is changed in octave units. It is. For example, when the note number assigned to the key number is C3 and the octave shift value is designated as "0", the pitch of C3 is generated at the timing of generating the pitch of C3. When the octave shift value is stored as "+1", the C3 is generated at the pitch of C4 shifted one octave upward at the timing of generating the pitch of C3. The velocity is data representing the velocity value (data used for controlling the volume, etc.) of the musical sound to be generated. Arpeggio sounding data corresponding to the number of keys pressed is generated according to the sound pattern data defined for each number of keys pressed.
[0022]
In the electronic musical instrument shown in FIG. 1, the number of key presses at the time of keyboard operation by the user is detected, and arpeggio sound data is generated by selectively using sound pattern data corresponding to the detected key press numbers. It is possible to generate an arpeggio having a natural sense of hearing according to the number of keys pressed. The arpeggio generation processing for generating such an arpeggio is performed when the CPU 1 of the electronic musical instrument shown in FIG. 1 executes a predetermined program (software) for realizing the arpeggio generation processing. Therefore, the processing operation of the “arpeggio generation processing” will be described with reference to FIG. FIG. 3 is a flowchart illustrating an example of the “arpeggio generation process”. This processing is executed when the device has been set to the arpeggio playing mode according to the operation of the arpeggio playing mode designating switch. Hereinafter, the processing operation of this processing will be described with reference to the flowchart shown in FIG.
[0023]
In step S1, the user selects a musical instrument type to be arpeggio-produced, and selects a type of arpeggio pattern data to be used for arpeggio generation from a plurality of stored arpeggio pattern data according to the specification of the musical instrument type. Is determined and the corresponding type of arpeggio pattern data is read. In step S2, it is checked whether or not a key pressing operation of each key in the arpeggio key range has been performed by the user. If the key pressing operation has been performed by the user, the process proceeds to step S1 in which the arpeggio pattern data already read out. Then, sound pattern data corresponding to the detected number of key presses is extracted (step S3). For example, one of the sound generation pattern data shown in FIG. 2B is extracted according to the number of keys pressed. In step S4, arpeggio sounding data is generated based on the sounding pattern data extracted in step S3.
[0024]
Here, arpeggio generation will be described using an example where the number of detected key presses is three. Now, assuming that three keys to which note numbers “C3”, “E3”, and “G3” included in the arpeggio key range are respectively pressed are pressed at the same time, the type of arpeggio pattern data for each type that has already been read out. The tone pattern data corresponding to the number of depressed keys 3 is selected from among them, and the key number “1 (Key = 1)” is “C3”, the key number “2 (Key = 2)” is “E3”, and the key number is “G3” is assigned to “3 (Key = 3)” (provided that the note numbers of the pressed keys in the arpeggio range are assigned in ascending order from the lower note number). ).
[0025]
Referring to the sounding pattern data of the number of key presses 3 shown in FIG. 2B, both the first beat (Timing = 0000) and the fourth beat (Timing = 1440) have the key numbers “1 (Key = Since “1)” is set, the pitch is determined by the note number “C3” assigned to the key number “1”. At this time, since the octave shift of the first beat is “+1 (Oct = + 1)”, the pitch of the first beat becomes the pitch of “C4” one octave higher than “C3”, and the octave of the fourth beat Since the shift is “+0 (Oct = + 0)”, the pitch of the fourth beat becomes the pitch of C3 as it is. Since the key number “3 (Key = 3)” is set for the second beat (Timing = 0480), the pitch is determined by the note number “G3” assigned to this key number “3”. Since the octave shift of the second beat is “+0 (Oct = + 0)”, the pitch of the second beat is “G3” as it is. Similarly, since the key number of the third beat is set to “2 (Key = 2)” and the octave shift is set to “+0 (Oct = + 0)”, the pitch of the third beat is “E3”. Pitch. In this way, when three keys respectively assigned with note numbers “C3”, “E3”, and “G3” included in the arpeggio key range are simultaneously pressed, the first beat is “C4”. An arpeggio for one bar composed of quarter notes (Gate = 480) having a pitch of "G3" on the second beat, "E3" on the third beat, and "C3" on the fourth beat is generated. Will be.
[0026]
As described above, the note number of the key pressed in the arpeggio range is referred to by the key number, and according to the sounding pattern data corresponding to the number of keys pressed, the note is played at the pitch of the note number, or the octave is shifted. Or pronounced at a different pitch. That is, the note number of the depressed key is pitch information that determines the pitch of the arpeggio component sound.
[0027]
Next, arpeggio generation when arpeggio pattern data is defined by fixed notes, that is, when a fixed note type arpeggiator is used, will be described with reference to FIG. FIG. 4A is a conceptual diagram showing an embodiment of an arpeggio output pattern generated using a fixed note type arpeggiator. Here, the horizontal axis represents time (Timing), and the output pattern is indicated by a circle. FIGS. 4B and 4C are conceptual diagrams respectively showing an embodiment of sound pattern data used in the fixed note type arpeggiator. In this embodiment, the bass drum, the snare drum, the hi-hat close, and the hi-hat correspond to the tone of the drum set in advance for a predetermined note, for example, the notes "C3", "E3", "B5", and "C6". An example in which each open drum sound is assigned will be described.
[0028]
There are two types of configurations for realizing an arpeggio output pattern as shown in FIG. 4A using a fixed note type arpeggiator as follows. First, as the first configuration, the above-described configuration, that is, a plurality of tone generation pattern data corresponding to the number of key presses for each type is prepared in advance as arpeggio pattern data, and the arpeggio generation corresponds to the number of key presses. This is a configuration in which an arpeggio is generated using generated sound pattern data. As shown in FIG. 4B, in this case, sound pattern data is defined so as to correspond to the number of key presses, and each sound pattern data includes timing (Timing), gate time (Gate), and note number. (Note), and data of one note composed of four elements of velocity (Vel) are stored for one bar. The timing, gate time, and velocity are the same as those shown in FIG.
[0029]
The note number is pitch information corresponding to each drum timbre. In the embodiment shown in FIG. 4B, only the note number “C3” is generated in the sound pattern data corresponding to the number of key presses 1, and the note number “C3” is generated in the sound pattern data corresponding to the number 2 of key presses. Note number "C3", "B5" and "C3 + E3" for the sound pattern data corresponding to "C3 + E3" and the number of key presses 3, and note numbers "B5" and "C3 + C6" for the sound pattern data corresponding to the number of key presses 4 "And" C3 + E3 + C6 "are defined together with the sounding timing, length, volume, and the like of each of the arpeggio constituent sounds. That is, the sound pattern data corresponding to the number of key depressions 1 is only the “bass drum” pattern, and the sound pattern data corresponding to the number of key depressions 2 is the “bass drum” pattern and the “merge of bass drum and snare drum” pattern. The sound pattern data corresponding to three key presses is a "bass drum" pattern, a "high hat open" pattern and a "merge of bass drum and snare drum" pattern, and the sound pattern data corresponding to four key presses is a "hi hat open" pattern. The number of musical instruments to be used is increased or decreased according to the number of keys pressed, such as a "merge of bass drum and hi-hat close" pattern and a "merge of bass drum, snare drum and hi-hat close" pattern (see FIG. 4A). Is stored in the sound pattern data, and the sound pattern data is switched according to the number of keys pressed. Instead to use.
[0030]
As described above, the configuration in which the sound pattern data corresponding to the number of keys pressed is prepared and the sound pattern data corresponding to the number of keys pressed by the user when generating the arpeggio is used for a fixed note type arpeggiator. This allows the fixed note type arpeggiator to increase the tone as the number of keys pressed increases, giving a natural and varied sense of hearing. Arpeggios can be generated.
[0031]
As a second configuration, a plurality of tone pattern data corresponding to each drum tone is prepared as arpeggio pattern data regardless of the number of keys pressed for each type, and these tone patterns are generated according to the number of keys pressed at the time of arpeggio generation. An arpeggio is generated by using one or more data in combination. For example, as shown in FIG. 4C, bass drum (note number "C3"), snare drum (note number "E3"), hi-hat open (note number "B5"), hi-hat close ( Four sound pattern data each having a defined note number "C6" are defined. When the number of keys pressed is 1, for example, only the "bass drum" pattern is generated using only the sound pattern data in which the note number "C3" is defined. When the number of key presses is two, for example, the "bass drum" and "snare drum" patterns are generated by combining the sound pattern data in which the note number "C3" and the note number "E3" are defined. When the number of key presses is three, for example, the sound pattern data in which the note number “C3”, the note number “E3”, and the note number “B5” are defined are combined to form “bass drum”, “snare drum”, Generate a "hi-hat open" pattern. If the number of key presses is 4, for example, the sound pattern data in which the note number “C3”, the note number “E3”, the note number “B5”, and the note number “C6” are defined is combined, and the “bass drum” , “Snare drum”, “hi-hat open”, and “hi-hat close” patterns.
[0032]
Even when the sound pattern data used according to the number of keys pressed is used in combination, the tone can be increased as the number of keys pressed increases in the fixed note type arpeggiator. It is possible to generate an arpeggio with a natural and varied audibility. Note that the combination of sound pattern data used in accordance with the number of key presses may be preset or may be appropriately set by the user.
[0033]
In the above-described embodiment, the number of keys pressed is four, but the number is not limited to four. When the number of key presses is larger than the planned number (for example, 5 or 6 sounds in the case of a planned 4 sounds), the one with the largest number of key presses in the prepared sounding pattern data is used. May be.
Note that, as the sounding pattern data used for the fixed note type arpeggiator, information specifying a sound effect instead of a note number may be defined. Alternatively, the note number and the information for designating the sound effect may be defined together, and the information used when generating the arpeggio may be switched and used based on the velocity at the time of key depression. For example, when the velocity is equal to or lower than a predetermined velocity value, a note number is used, and when the velocity is higher than the predetermined velocity value, information for designating a sound effect is used.
[0034]
The format of the sound pattern data is “event + relative time” in which the occurrence time of each event is represented by the time from the immediately preceding event, and “event” in which the occurrence time of the event is represented by an absolute time in a song or bar. "Absolute time", "pitch (rest) + note length" expressed in note pitch and note length or rest and rest length, memory area is secured for each minimum resolution of performance, and events occur The event may be in any form, such as a “solid method” in which the event is stored in a memory area corresponding to the time of the event.
[0035]
【The invention's effect】
According to the present invention, an arpeggio pattern that provides a natural audibility in accordance with the number of previously operated performance operators is stored, the number of performance operators operated by the user is detected, and the corresponding performance operator is detected. Since arpeggios are generated by selectively using arpeggio patterns according to the number, the user can easily generate arpeggios having a natural audibility according to the number of operating operators operated. The effect is obtained.
