【００２５】
なお、表１の「’」は「フィート」を示し、ハイフン「−」は帯分数を示す。また、「パーカッション」とは、押鍵時に瞬時的に発音され、その後、徐々に減衰する特性を有する音色を示す。
【００２６】
そして、上記のように１８本のスライダーＳ-1〜Ｓ-18を用いることにより、一つの鍵を押鍵すると、該鍵を基音とした１８種の音高或いはパーカッションを合成した音が発音されるので、従来の電子オルガンと比較して、より多くの倍音成分、或いはパーカッションの成分を含んだ臨場感のある音を出力することができる。
【００２７】
また、１８本のスライダーＳ-1〜Ｓ-18を、左側からＳ-1〜Ｓ-18の順序で配列することにより、従来より使用されている９本のスライダーＳ-1〜Ｓ-9が従来どおりに配列されるので、奏者は従来と同様の感覚で９本のスライダーＳ-1〜Ｓ-9を操作することができ、且つ、これとは別に、追加された９本のスライダーＳ-10〜Ｓ-18をも操作することができるようになる。
【００２８】
また、図１に示した折り返し制御部３ａは、基音に対する倍音成分が、オルガンの高音域に達した場合には、この倍音成分を折り返す制御を行う。つまり、基音に対して倍率の高い音高は、周波数が極めて高くなることがあり、この音高を出力しても、和音的にあまり意味がない。例えば、基音の周波数が２６１Ｈｚである場合には、この３２倍音の周波数は８３７２Ｈｚとなり（丁度３２倍とならないのは、小数点以下の数値の処理による）、このような高い周波数の音は、人間の耳で聞き取りにくい周波数の領域であるのでこの音高を出力することは和音的にあまり意味がなく、むしろ音量感が減少して不自然な感じを与える。また、低い周波数帯域においても同様のことが言える。
【００２９】
そこで、本実施形態では、高音域、或いは低音域に達した倍音成分については、適宜折り返しの処理を加えることにより、発音される音の音量感を低減させることなく、且つ、自然な音感を損なうことなく発音させる。
【００３０】
折り返しの例として、例えば、図３に示すように設定することができる。この例では、１６’（基音よりも１オクターブ低い音）については、鍵ｋ-13で１オクターブ上昇するように折り返し処理を加えている。また、２’（４倍音）は、鍵ｋ-49で１オクターブ低下するように折り返し処理を加えている。同様に、１／４’（３２倍音）は、鍵ｋ-25、ｋ-37、ｋ-49の３つの音高でそれぞれ１オクターブ低下するように折り返し処理を加えている。なお、図３では、１８本のスライダーのうち主要な７本のスライダーについてのみ、折り返しのチャート図を示しているが、その他のスライダーについても同様に、所望の箇所で折り返し処理が加えられる。
【００３１】
このようにして、本実施形態における電子オルガン１では、スライダーを１８本搭載し、これらの各スライダー（Ｓ-1〜Ｓ-18）に各種の音高或いはパーカッション（音色）を割り当てる構成としている。従って、１つの鍵を押鍵すると、この鍵を基音として合計１８種の音高或いはパーカッションが同時に出力されるので、従来より使用されている９本のスライダーを具備した電子オルガンと比較して、臨場感、アタック感に富んだ音色を出力することができる。
【００３２】
また、高音域、或いは低音域に達する音高は、適宜折り返しの処理が加えられるので、音量感を減衰させることなく、自然な音色を出力することが可能となる。更に、スライダー群Ｓに搭載される１８本のスライダーのうち、９本のスライダーＳ-1〜Ｓ-9については、従来の電子オルガンにて使用されているスライダーと同一の配列とし、新たに追加するスライダーＳ-10〜Ｓ-18に、従来の９本のスライダーＳ-1〜Ｓ-9とは異なる音高或いはパーカッションが割り当てられるので、奏者は従来通りの操作感覚で、９本のスライダーＳ-1〜Ｓ-9を操作することができ、操作性が良い。
【００３３】
図４は、上記した第１の実施形態の電子オルガン１における、折り返し処理の変形例を示す説明図である。同図に示すように、この折り返し処理では、基音に対する全ての倍音成分或いはパーカッションに対し、１オクターブ毎に折り返し処理を加えるように構成している。即ち、８’（基音）の音階を例にとると、鍵ｋ-1から鍵ｋ-12まで徐々に音階が上昇し、鍵ｋ-13で、１オクターブ下の音階（鍵ｋ-1と同一の音階）に折り返される。その他の倍音成分及びパーカッションについても同様の処理が加えられる。
【００３４】
そして、このような折り返し処理を加えることにより、奏者が鍵盤ｋを左側から右側に向けて順次押鍵すると、あたかも音階が無限に上昇するような音色を出力することができる。即ち、実際には鍵ｋ-1と、ｋ-13は同一の１８種の倍音成分及びパーカッションが出力されるようになされているが、鍵ｋ-1、ｋ-2、・・と順次押鍵すると、人間の耳には、鍵ｋ-13を越えてもあたかも音階が上昇している如くの音感が得られる。
【００３５】
このような構成によれば、音階が無限に上昇する如くの音色を得ることができるので、ライブ演奏時等において極めて有用である。
なお、上記した実施形態では、表１に示す９本のスライダーＳ-10〜Ｓ-18を追加搭載する例について説明したが、本発明はこれに限定されるものではなく、例えば、追加搭載する９本のスライダーＳ-10〜Ｓ-18のうちの一つを削除し、その代わりに１０倍音を操作可能なスライダーを割り当てるように構成することもできる。
【００３６】
また、上記した実施形態では、従来より使用されている９本のスライダーＳ-1〜Ｓ-9を配置し、これに対して新たに９本のスライダーＳ-10〜Ｓ-18を追加搭載する例について説明したが、本発明はこれに限定されるものではなく、追加搭載するスライダーの本数は、１以上であれば本発明の効果を達成することができる。例えば、従来の９本のスライダーＳ-1〜Ｓ-9に対して、この９本のスライダーとは異なる音高或いは音色の出力レベルを操作可能な１本のスライダーを追加し、合計１０本のスライダーを使用して、出力音色を調整するようにしても良い。
【００３７】
更に、上記した実施形態では、９本のスライダーを具備した電子オルガンに対し、１本以上のスライダーを追加搭載する例について説明したが、例えば、９本のスライダーを複数セット具備した電子オルガンに対し、このうちの１つのセットとなるスライダー群に対して、１本以上のスライダーを追加搭載する構成とすることもできる。このような構成においても上記と同様の効果を得ることができる。
【００３８】
次に、本発明の第２の実施形態について説明する。従来の電子オルガンにおいては、９本のスライダー群を２セット有し、合計１８本のスライダーを具備したタイプのものが実用に供されている。このような電子オルガンでは、基音に対する倍音比が全て同一とされた２セットのスライダー群の各スライダーを、所望の出力レベルに設定し、奏者が演奏する楽曲に応じて適宜スライダー群を選択することにより、楽曲にあった倍音比を設定することができる。
【００３９】
本実施形態の電子オルガンでは、従来より使用されている１８本のスライダーを、従来と同様の９本２セットとして使用するモード（第１のモード）と、新たに追加する１８本１セットとして使用するモード（第２のモード）とを切り換えて使用するものである。
【００４０】
図５は、第２の実施形態に係る電子オルガン２１の構成を示す外観図、図６は内部構成を示すブロック図である。図示のように、この電子オルガン２１は、９本のスライダーを１セットとしたスライダー群が２セット設置され、合計１８本のスライダーが設置されている。即ち、第１のスライダー群Ｓａは９本のスライダーＳ-21〜Ｓ-29を具備し、第２のスライダー群Ｓｂは９本のスライダーＳ-31〜Ｓ-39を具備している。更に、モード選択スイッチ７が搭載され、該モード選択スイッチ７を操作することにより、１８本のスライダーを９本ずつの２セットとするモード（第１のモード）と、１８本１セットとするモード（第２のモード）とを切り換えることができるように構成されている。
【００４１】
そして、このような構成において、モード選択スイッチ７にて第２のモードを選択すれば、上記した第１の実施形態と同様に、押鍵した鍵を基音とする１８種の音高、或いはパーカッションが出力されるので、従来の９本のスライダーを使用する場合と比較して極めて臨場感に富む音色を出力することが可能となる。
【００４２】
また、第１のスライダー群Ｓａは、従来より使用されている９本のスライダーと同様の倍音比を有する音高が設定され、第２のスライダー群Ｓｂに、新たな倍音比となる音高、或いはパーカッションが設置されるので、奏者は従来通りの操作感覚で第１のスライダー群Ｓａを操作することができ、更に、第２のスライダー群Ｓｂに新たに追加された倍音比となる音高、或いはパーカッションを出力することができる。
【００４３】
また、モード選択スイッチ７により、第１のモードを選択すれば、従来通りに９本を１セットとしたスライダー群を２セット具備することになるので、奏者は演奏する楽曲に合わせて、適宜２つのスライダー群Ｓａ、Ｓｂを選択することができ、汎用性の高い演奏が可能となる。
【００４４】
更に、本実施形態においても、上記した第１の実施形態と同様に、倍音成分が高音域、或いは低音域に達する場合に、これを折り返す処理を加えることにより、音量感を損なうことのない自然な音色を出力することができる。また、各スライダーに割り当てられる倍音、或いはパーカッションの全てを１オクターブ毎に折り返すように構成すれば、あたかも無限に音階が上昇する如くの音色を出力することができるようになる。
【００４５】
【発明の効果】
以上説明したように、本発明に係る電子オルガンでは、従来より使用されている９本のスライダーに対し、これら９本のスライダーとは音高、或いは音色が異なる新たなスライダーを少なくとも１本追加搭載しているので、従来の電子オルガンと比較すると、より汎用性に富み、且つ臨場感の高い音色を出力することができるようになる。
【００４６】
また、本発明に係る電子オルガンのスライダー割り当て方式によれば、従来より用いられている９本２セットで合計１８本のスライダーを有する電子オルガンにおいて、スライダーの割り当てを第１のモード、或いは第２のモードに切り換えることにより、汎用性に富む使用形態を選択することができる。即ち、９本２セットとする第１のモードを選択すると、従来より使用されている９本２セットのスライダーを具備する電子オルガンと同様の操作が可能となり、他方、１８本１セットとする第２のモードを選択すると、従来より使用されている９本のスライダーに対して、更に、新たな９種の音高、或いは音色（パーカッション）が追加されるので、より臨場感のある音色を出力することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electronic organ having a slider and a slider assignment method for the electronic organ, and more particularly to a technique for improving the acoustic effect of an output timbre.
[0002]
[Prior art]
In recent years, an electronic organ that is often used as an electronic musical instrument is provided with a slider (also referred to as a draw bar) in order to simulate an electromagnetic mechanical organ that has been used conventionally.
[0003]
An electronic organ usually has nine sliders, and each of the nine sliders has a fundamental tone (8 '), a second harmonic (4'), a third harmonic (2-2 / 3 '), and a fourth harmonic. (2 '), 5th harmonic (1-2 / 3'), 6th harmonic (1-1 / 3 '), 8th harmonic (1'), 1 octave lower than the fundamental (16 '), 3' Overtone (5-1-3 ') is assigned. Note that “′” corresponds to “feet”, and the hyphen “−” indicates a mixed number.
[0004]
When an arbitrary keyboard of the electronic organ is pressed, the above nine types of overtones are output simultaneously with the pitch corresponding to the keyboard as a base tone, so that a tone unique to the organ can be obtained. For example, when the C key at the center of the organ is pressed, this pitch becomes the fundamental tone, and each pitch as shown in the score of FIG. 7 is output. Further, in addition to the nine sliders, a tablet switch is provided so that a second harmonic percussion and a third harmonic percussion can be synthesized. Percussion is a timbre that changes so that a sound is output instantaneously and then gradually attenuates.
[0005]
By operating each slider, the output volume of each overtone can be adjusted. Therefore, by appropriately setting the slider, it is possible to output a timbre that suits the player's preference. For example, if you want to reduce the output of the 5th harmonic among the above nine pitches, operate the slider (1-2 / 3 ') corresponding to this 5th harmonic to output the output level of the 5th harmonic. Can be suppressed.
[0006]
However, the above-described conventional electronic organ synthesizes harmonic components up to the eighth harmonic, cannot synthesize more harmonic components, and cannot completely eliminate the so-called Hammond-like tone. In particular, there is a shortage of higher harmonics in natural overtones, and there is a limit to the acoustic effective spread. Furthermore, the pitch to which the percussion effect is added is only 2nd tone (2 '(4') and 3rd tone (2-2 / 3 ')), which is a limitation in adding an attack feeling to the synthesized sound. It was.
[0007]
[Problems to be solved by the invention]
As described above, in the conventional electronic organ, the pitch of the pressed key is used as a fundamental tone, and eight types of pitches with a desired overtone ratio with respect to this fundamental tone (a total of nine different pitches including the fundamental tone). However, it was not able to respond to the desire to synthesize higher harmonic components. In addition, by operating the tablet switch, it is possible to synthesize two types of percussion output (second overtone and third overtone), but other percussion outputs at other pitches cannot be synthesized, making the attack more powerful. There was a drawback that a feeling could not be added.
[0008]
The present invention has been made to solve such a conventional problem, and the object of the present invention is not to impair the function of a slider that has been used in the past, and to provide more pitches or To provide an electronic organ capable of synthesizing percussion output and a slider assignment method used for the electronic organ.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, an electronic organ according to claim 1 of the present application is:
There are 2 sets of 9 sliders that can be output by appropriately adjusting the output level of 9 pitches with the desired harmonic ratio to the pitch of the input keyboard.

The 9 sliders mounted in the slider group are set so that the pitch or tone (percussion) is different from the 9 sliders mounted in the other slider group, and a total of 18 sliders is a set of sliders. It was configured to switch between the second mode used as a group.
[0010]
Also, the electronic organ of the present invention is a slider comprising a set of nine sliders that can be output by appropriately adjusting the output levels of nine pitches or timbres that have a desired harmonic ratio relative to the pitch of the input keyboard. In an electronic organ having a plurality of groups, at least one of the plurality of sets of sliders further has a pitch or timbre having a desired overtone ratio with respect to the pitch of the input keyboard. One or more sliders that can be output by adjusting the output level are additionally installed, and a total of 10 or more sliders are provided.
[0011]

In the electronic organ provided, the slider group further includes nine sliders that differ in pitch or tone (percussion) from the nine sliders with respect to the pitch of the input keyboard. A total of 18 sliders were provided.
[0012]

In the electronic organ of the present invention, the pitch or timbre assigned to each slider is subjected to folding processing in at least one of the high sound range and the low sound range.
[0014]
In the electronic organ of the present invention, the pitch or timbre (percussion) assigned to each of the sliders is subjected to a folding process every time an octave rises in the entire range of the electronic organ.
[0015]

[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing a configuration of a first embodiment of an electronic organ to which the present invention is applied, and FIG. 2 is a block diagram showing an internal configuration of the electronic organ.
[0021]
As shown in FIG. 1 and FIG. 2, the electronic organ 1 has a sound range of about 5 octaves as a whole, and is composed of 61 keys k-1 to k-61 (white key and black key). k, a CPU 3 that generally controls the electronic organ 1, a tone generator circuit 4 that generates and outputs a musical sound signal under the control of the CPU 3, a D / A converter 5, and an external MIDI device. And a MIDI interface 6 for transmitting and receiving signals. Furthermore, a slider group S composed of sliders S-1 to S-18, each having 18 sets, is provided.
[0022]
The CPU 3 includes a turn-back control unit 3a. In the turn-back control unit 3a, when the pitch that is the harmonic component of the key that has been pressed (fundamental tone) reaches the high range or the low range, this is appropriately set. Perform the wrapping process. For example, when the frequency of a pitch that is 32 times higher than the fundamental tone is extremely high, and the frequency band is not very meaningful in terms of musical tone, this pitch is switched to a pitch one octave below (this Can be output as a natural timbre.
[0023]
Next, the operation of the present embodiment configured as described above will be described. In the present embodiment, nine of the eighteen sliders S-1 to S-18 (S-1 to S-9) have a pitch similar to that of a slider used in a conventional electronic organ ( Overtone components are assigned, and the remaining nine sliders (S-10 to S-18) are assigned different pitches (overtone components) or percussion from the nine sliders. For example, the allocation is set as shown in Table 1 below.
[0024]
[Table 1]

[0025]
In Table 1, “′” indicates “feet”, and a hyphen “−” indicates a mixed number. Further, “percussion” indicates a timbre that has a characteristic of being pronounced instantaneously when a key is pressed and then gradually attenuated.
[0026]
Then, by using the 18 sliders S-1 to S-18 as described above, when one key is pressed, 18 kinds of pitches or percussion sounds based on the key are generated. Therefore, compared to a conventional electronic organ, it is possible to output a realistic sound including more harmonic components or percussion components.
[0027]
In addition, by arranging 18 sliders S-1 to S-18 in the order of S-1 to S-18 from the left side, the nine sliders S-1 to S-9 that have been used in the past can be obtained. Since it is arranged in the conventional manner, the player can operate the nine sliders S-1 to S-9 with the same feeling as before, and separately, nine additional sliders S- 10 to S-18 can be operated.
[0028]
Further, the turn-back control unit 3a shown in FIG. 1 performs control to turn over the harmonic component when the harmonic component with respect to the fundamental tone reaches the high range of the organ. That is, a pitch with a high magnification relative to the fundamental tone may have a very high frequency, and even if this pitch is output, there is not much meaning in terms of chords. For example, if the fundamental tone frequency is 261 Hz, the frequency of this 32nd harmonic is 8372 Hz (the fact that it is not exactly 32 times is due to the processing of numerical values after the decimal point). Since it is a frequency region that is difficult to hear by the ear, outputting this pitch does not make much sense in terms of chords, but rather reduces the sense of volume and gives an unnatural feeling. The same applies to the low frequency band.
[0029]
Therefore, in the present embodiment, the harmonic sound component that has reached the high sound range or the low sound range is appropriately subjected to a folding process, thereby reducing the volume of the sound to be generated and reducing the natural sound feeling. Make them pronounce without any problems.
[0030]
As an example of folding, for example, it can be set as shown in FIG. In this example, 16 ′ (a sound one octave lower than the fundamental tone) is subjected to a folding process so that the key k-13 increases by one octave. For 2 '(fourth harmonic), a folding process is added so that the key k-49 lowers by one octave. Similarly, for 1/4 ′ (32 overtones), folding processing is added so that each of the three pitches of the keys k-25, k-37, and k-49 decreases by one octave. In FIG. 3, only the main seven sliders of the 18 sliders are shown as charts for folding, but the other sliders are similarly subjected to folding processing at a desired location.
[0031]
In this way, the electronic organ 1 according to the present embodiment has a configuration in which 18 sliders are mounted and various pitches or percussion (tone colors) are assigned to these sliders (S-1 to S-18). Therefore, when one key is pressed, a total of 18 pitches or percussion is output simultaneously with this key as a fundamental tone. Compared to the conventional electronic organ with nine sliders, Sounds with a rich sense of presence and attack can be output.
[0032]
In addition, since the pitches that reach the high or low pitch range are appropriately turned back, a natural tone color can be output without attenuating the volume feeling. Furthermore, of the 18 sliders mounted on the slider group S, 9 sliders S-1 to S-9 have the same arrangement as the sliders used in conventional electronic organs and are newly added. Since the sliders S-10 to S-18 are assigned different pitches or percussion from the conventional nine sliders S-1 to S-9, the player can operate the nine sliders S with the conventional operation feeling. -1 to S-9 can be operated and operability is good.
[0033]
FIG. 4 is an explanatory view showing a modification of the folding process in the electronic organ 1 of the first embodiment. As shown in the figure, this folding process is configured to add a folding process every octave to all overtone components or percussion with respect to the fundamental tone. That is, taking the scale of 8 '(fundamental tone) as an example, the scale gradually rises from the key k-1 to the key k-12, and with the key k-13, the scale one octave below (same as the key k-1) ). Similar processing is applied to other harmonic components and percussion.
[0034]
By adding such a turn-back process, it is possible to output a tone color that makes the scale rise infinitely when the player sequentially presses the keyboard k from the left side to the right side. That is, in practice, the keys k-1 and k-13 are designed to output the same 18 types of overtone components and percussion, but the keys k-1, k-2,. Then, even if the key k-13 is exceeded, the human ear can feel as if the scale is rising.
[0035]
According to such a configuration, it is possible to obtain a tone color in which the scale rises indefinitely, which is extremely useful when performing live performances.
In the above-described embodiment, the example in which the nine sliders S-10 to S-18 shown in Table 1 are additionally mounted has been described. However, the present invention is not limited to this, and for example, the additional mounting is performed. It is also possible to delete one of the nine sliders S-10 to S-18 and assign a slider capable of operating a tenth harmonic instead.
[0036]
In the above-described embodiment, nine sliders S-1 to S-9 that have been conventionally used are arranged, and nine sliders S-10 to S-18 are additionally mounted on the nine sliders S-1 to S-9. Although an example has been described, the present invention is not limited to this, and the effect of the present invention can be achieved if the number of additional sliders is one or more. For example, in addition to the nine conventional sliders S-1 to S-9, one slider that can operate the output level of a pitch or tone different from these nine sliders is added, for a total of ten sliders. The output tone may be adjusted using a slider.
[0037]
Furthermore, in the above-described embodiment, an example in which one or more sliders are additionally mounted on an electronic organ having nine sliders has been described. For example, for an electronic organ having a plurality of nine sliders. A configuration in which one or more sliders are additionally mounted on the slider group as one set of these can also be adopted. Even in such a configuration, the same effect as described above can be obtained.
[0038]
Next, a second embodiment of the present invention will be described. In the conventional electronic organ, a type having two sets of nine slider groups and a total of 18 sliders is put into practical use. In such an electronic organ, each slider of the two sets of slider groups having the same harmonic ratio to the fundamental tone is set to a desired output level, and the slider group is appropriately selected according to the music played by the player. Thus, it is possible to set the harmonic ratio suitable for the music.
[0039]
In the electronic organ of the present embodiment, the 18 sliders that have been conventionally used are used as a mode in which 9 sliders are used as 2 sets as in the past (first mode) and as a set of 18 bars that are newly added. The mode to be used (second mode) is switched and used.
[0040]
FIG. 5 is an external view showing the configuration of the electronic organ 21 according to the second embodiment, and FIG. 6 is a block diagram showing the internal configuration. As shown in the figure, the electronic organ 21 has two sets of slider groups each including nine sliders, and a total of 18 sliders. That is, the first slider group Sa includes nine sliders S-21 to S-29, and the second slider group Sb includes nine sliders S-31 to S-39. Furthermore, a mode selection switch 7 is mounted, and by operating the mode selection switch 7, a mode in which 18 sliders are set in two sets of nine (first mode) and a mode in which 18 sets of 18 are set. (Second mode) can be switched.
[0041]
In such a configuration, when the second mode is selected by the mode selection switch 7, 18 kinds of pitches or percussion based on the key pressed are used as in the first embodiment. Therefore, it is possible to output a timbre that is extremely realistic compared to the case where nine conventional sliders are used.
[0042]
In addition, the first slider group Sa is set with a pitch having the same harmonic ratio as the nine sliders conventionally used, and the second slider group Sb has a new pitch ratio. Alternatively, since the percussion is set, the player can operate the first slider group Sa with the conventional operation feeling, and furthermore, the pitch that becomes the harmonic ratio newly added to the second slider group Sb, Alternatively, percussion can be output.
[0043]
Further, if the first mode is selected by the mode selection switch 7, two sets of 9 sliders are provided as usual, so that the player can select 2 according to the music to be played. Two slider groups Sa and Sb can be selected, and a highly versatile performance is possible.
[0044]
Further, in the present embodiment as well, as in the first embodiment described above, when a harmonic component reaches a high sound range or a low sound region, a natural sound that does not impair the volume feeling is added by adding a process of turning this over. Sound can be output. If all the harmonics or percussion assigned to each slider are folded back every octave, it is possible to output a tone that makes the scale rise indefinitely.
[0045]
【The invention's effect】
As described above, in the electronic organ according to the present invention, at least one new slider having a pitch or tone different from those of the nine sliders is added to the nine sliders conventionally used. Therefore, it is possible to output a timbre that is more versatile and has a higher sense of realism than a conventional electronic organ.
