[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument having an arbitrary assignment operator (dot button) that can selectively and arbitrarily assign tone control information including a large number of timbres, rhythm patterns, and accompaniment patterns.

[0002]

2. Description of the Related Art A conventional electronic musical instrument has a tone color selection switch group corresponding to each tone color. When these tone color selection switch groups are selectively operated by an operator, the selected tone color selection operation is performed. It operated as an electronic musical instrument capable of producing musical tones of the tone corresponding to the switch. Some conventional electronic musical instruments include 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, if such a tone selection switch group or the like is provided on the operation panel of an electronic musical instrument in accordance with the type of the tone or the like, an extremely large number of switches must be provided. There is a problem that the space becomes large and the cost becomes high. Therefore, recently, an electronic musical instrument has been developed which can select and set many tone colors and the like as appropriate without increasing the number of tone color selection switches. Examples of such electronic musical instruments include, for example, JP-A-61-176991, JP-A-62-187893, and JP-A-62-23598.
No. 9 and JP-A-62-187394.

In the electronic musical instruments described above, in addition to a plurality of normal tone color selection switches to which unique tone colors are assigned, any one of the unique tone colors is selectively assigned. It has an arbitrarily assigned tone switch or the like (dot button). An electronic musical instrument having such a dot button can selectively set a desired one from many timbres and the like with a limited number of switches, thereby expanding the degree of freedom in selecting and setting timbres and the like. can do.

[0005]

[Problems to be Solved by the Invention] However, some electronic musical instruments include a plurality of keyboards (such as an upper keyboard,
In some cases, different tones and the like can be assigned to the lower keyboard and the pedal keyboard, respectively. Such an electronic musical instrument has a normal tone color selection switch or the like, a dot button, or the like for each key. That is, in the case of an electronic musical instrument having a plurality of keys 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, and a switch provided adjacent thereto. The upper keyboard dot button, the lower keyboard tone selection switch for selecting the tone that can be assigned to the lower keyboard, the lower keyboard dot button provided adjacent thereto, and the assignable to the pedal keyboard It has a pedal keyboard tone color selection switch for selecting a tone color, and a pedal keyboard dot button provided adjacent to the switch.

[0006] In such an electronic musical instrument, if the tone color exists in the tone color selection switch, the tone color of the keyboard which does not correspond can be selectively assigned to the dot button. That is, even when a certain tone does not exist in the upper keyboard tone color selection switch, but exists in the lower keyboard tone color selection switch, the tone color can be assigned to the upper keyboard dot button. The operation of assigning a tone to the dot button is performed between the tone selection switch and the dot button between the upper keyboard and the lower keyboard, between the upper keyboard and the pedal keyboard, and between the lower keyboard and the pedal keyboard. This can be performed arbitrarily, and the timbre usable by the player can be substantially increased.

However, the tone color selection switch corresponding to each keyboard is assigned a tone color (a parameter relating to the tone color) created in consideration of how to be used in the performance of each keyboard. That is, the tone selection switch for the upper keyboard has a tone optimal for playing the upper keyboard, the tone selection switch for the lower keyboard has a tone optimal for playing the lower keyboard, and the tone selection switch for the pedal keyboard has a tone for playing the pedal keyboard. The optimal tone is assigned to each. Therefore, even if the tone assignment to the dot buttons is simply performed between the upper keyboard and the lower keyboard, between the upper keyboard and the pedal keyboard, and between the lower keyboard and the pedal keyboard, the desired tone is assigned to each keyboard. It could not be assigned to the corresponding dot button.

The present invention has been made in view of the above-mentioned point, and an arbitrary assignment operator provided corresponding to a plurality of keys having different playing styles is matched to the playing style of the keyboard corresponding to the arbitrary assigning operator. It is an object of the present invention to provide an electronic musical instrument to which tone control information such as timbre can be assigned.
