[0001]

[Industrial applications]

 The present invention relates to an electronic musical instrument having an arbitrary assigning operator (dot button) capable of selectively and arbitrarily assigning musical tone control information consisting of a large number of tone colors, rhythm patterns, accompaniment patterns and the like.

[0002]

[Prior Art]

 A conventional electronic musical instrument has a tone color selection switch group corresponding to each tone color, and when these tone color selection switch groups are selectively operated by an operator, the selected tone color selection switch is selected. It was operating as an electronic musical instrument capable of producing tones with the corresponding tones. Some conventional electronic musical instruments have a rhythm selection switch group and an accompaniment selection switch group provided for each type of rhythm pattern and accompaniment pattern, in addition to the tone color selection switch group.

However, when such a tone color selection switch group or the like is to be provided on the operation panel of the electronic musical instrument according to the type of the tone color or the like, it is necessary to provide a very large number of switches. There was a problem that the installation space would be large and the cost would be high. Therefore, recently, an electronic musical instrument has been developed in which a large number of timbres and the like can be appropriately selected and set without increasing the number of timbre selection switches. Examples of such electronic musical instruments include those described in JP-A-61-176991, JP-A-62-187893, JP-A-62-235989 and JP-A-62-187394. is there.

In the electronic musical instruments described in these, in addition to a plurality of normal tone color selection switch groups to which unique tone colors and the like are respectively assigned, any one of these unique tone colors and the like is selectively assigned. It has an arbitrarily assigned tone color switch (dot button). With an electronic musical instrument having such a dot button, a desired one can be selectively set from a large number of tones by a limited number of switches, and the degree of freedom in selection settings of tones and the like is increased. Can be extended.

[0005]

[Problems to be solved by the device]

 However, some electronic musical instruments, such as an electronic organ, are capable of assigning different tones to a plurality of keyboards (upper keyboard, lower keyboard and pedal keyboard). Such an electronic musical instrument has an ordinary tone color selection switch or dot button for each keyboard. That is, in the case of an electronic musical instrument having a plurality of keyboards such as an upper keyboard, a lower keyboard and a pedal keyboard, an upper keyboard tone selection switch for selecting a tone that can be assigned to the upper keyboard Assigned to the upper keyboard dot button, the lower keyboard tone selection switch for selecting the tones that can be assigned to the lower keyboard, the lower keyboard dot button adjacent to this, and the pedal keyboard. It has a pedal keyboard tone color selection switch for selecting a possible tone color, and a pedal keyboard dot button provided adjacent thereto.

In such an electronic musical instrument, any tone color existing in the tone color selection switch can be selectively assigned to a dot button even if the tone color of the keyboard is not compatible. That is, even if a certain tone color does not exist in the upper keyboard tone color selection switch but exists in the lower keyboard tone color selection switch, that tone color can be assigned to the upper keyboard dot button. This kind of operation for assigning tones to the dot buttons is performed between the upper and lower keyboards, between the upper and pedal keyboards, and between the lower and pedal keyboards with the respective tone color selection switches and dot buttons. This is very effective because it can be arbitrarily performed in between, and the timbre that can be used by the performer can be substantially increased.

However, the tone color selection switch corresponding to each keyboard is assigned a tone color (parameter relating to tone color) created in consideration of how each keyboard is used in playing. That is, the tone selection switch for the upper keyboard is the tone optimal for playing the upper keyboard, the tone selection switch for the lower keyboard is the tone optimal for playing the lower keyboard, and the tone selection switch for the pedal keyboard is the tone of the pedal keyboard. The optimal tones for the performance are assigned. Therefore, even if you simply assign a tone to a dot button between the upper and lower keyboards, between the upper and pedal keyboards, and between the lower and pedal keyboards, you can obtain the desired tone on each keyboard. It could not be assigned to the corresponding dot button.

The present invention has been made in view of the above points, and is adapted to an arbitrarily assigned operator provided corresponding to a plurality of keyboards each having a different playing form, and adapted to the playing form of the corresponding keyboard. It is an object of the present invention to provide an electronic musical instrument to which musical tone control information such as a specified tone color can be assigned.

[0009]

[Means for Solving the Problems]

 An electronic musical instrument according to the present invention is provided with a first selecting means having a plurality of operators for selecting musical tone control information regarding a first tone group, and a musical tone control information regarding a second tone group. At least a second selection means having a plurality of operators and an operator for assigning arbitrary musical tone control information, and selecting the assigned musical tone control information as the musical tone control information for the first sound group. A third selection means provided with one, and a first assignment control for assigning to the third selection means musical tone control information relating to the first sound group corresponding to an arbitrary operator in the first selection means. Means and the tone control information about the second sound group corresponding to an arbitrary operator in the second selecting means can be assigned to the third selecting means, and the tone control assigned at the time of the assignment It is obtained by a second assignment control means for assigning to change at least a portion of the distribution to the content corresponding to the first sound group.

[0010]

[Action]

 An electronic musical instrument has a plurality of keyboards (upper keyboard, lower keyboard and pedal keyboard) such as an electronic organ, and a different sound group is assigned to each keyboard. The first selection means is provided with a plurality of operators for selecting the musical tone control information relating to the first sound group (for example, the upper keyboard) of such sound groups. The second selection means is provided with a plurality of operators for selecting the musical tone control information regarding the second sound group (for example, the pedal keyboard). The third selecting means is capable of assigning arbitrary musical tone control information, and is provided with at least one operator for selecting the assigned musical tone control information as musical tone control information regarding the first sound group. , Which is usually called a dot button. The third selecting means selects the assigned musical tone control information as the musical tone control information regarding the first sound group. Therefore, the third assigning means causes the first assigning controlling means to select an arbitrary operator in the first selecting means. When the tone control information on the first tone group corresponding to is assigned, the tone control information on the first tone group can be selected as it is.

Further, the third selection means may be assigned the tone control information regarding the second sound group corresponding to an arbitrary operator in the second selection means by the second assignment control means. At this time, if the musical tone control information regarding the second tone group is directly assigned to the third selecting means, it is meaningless to assign a different tone group to each keyboard. Therefore, in this invention, when the second assignment control means assigns the tone control information regarding the second sound group corresponding to an arbitrary operator in the second selection means to the third selection means, At least a part of the musical sound control information of the second sound group is changed and assigned to the content corresponding to the first sound group. As a result, the third selection means is assigned the second tone control information even when the second assignment control means assigns the tone control information regarding the second tone group corresponding to an arbitrary operator in the second selection means. It becomes possible to select the tone control information regarding the tone group of as the tone control information regarding the first tone group. Therefore, even when different tone groups are assigned to each keyboard, musical tone control information can be arbitrarily assigned between different tone groups, and the degree of freedom in tone color selection can be expanded.
