DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device, and more particularly, to a timbre, a volume, an effect (reverb,
Various parameter information of the electronic musical instrument, such as parameter information relating to the characteristics of musical sounds such as chorus and parameter information relating to the playing method such as an accompaniment pattern in automatic accompaniment, are arbitrarily assigned to appropriate controls. The present invention relates to a parameter setting device in which, when an operator to which parameter information is assigned is operated, the current setting state of the parameter information is switched to the parameter information assigned to the operated operator.

[0002]

2. Description of the Related Art In general, in an electronic musical instrument, parameter information relating to characteristics of musical tones such as timbre, volume, effects (reverb, chorus, etc.) and an accompaniment pattern in an automatic accompaniment (hereinafter, an accompaniment pattern in an automatic accompaniment is referred to as a "style"). A variety of parameter information such as parameter information relating to a performance method such as "."

[0003] In a conventional electronic musical instrument, in order to arbitrarily set parameter information larger than the number of controls with a small number of controls for the purpose of cost reduction or the like, the number of parameter information that can be selected in the electronic musical instrument is reduced. Arbitrary parameter information can be appropriately allocated to a small number of operators as needed.

[0004] As described above, as a method of assigning arbitrary parameter information to each operator, for example, the following two types of methods have been known.

(First Method) In a first method, an operator to which parameter information such as a tone selection button or a style selection button is allocated is appropriately selected, and the selected operation is performed by parameter changing means. When the operation of changing the parameter information assigned to the selected operator is performed, the parameter information assigned to the selected operator is temporarily changed. However, the temporarily changed parameter information is not definitely assigned to the selected operator.
Therefore, in the first method, an operation such as selection of another tone color selection button or a style selection button is performed on the selected operator without performing the parameter information finalizing operation by the parameter finalizing button. If
The selected operator remains in a state in which the parameter information before being changed by the parameter changing means is allocated. For this reason, after that, when the selected operator is selected again and the parameter information assigned to the selected operator is to be read, the parameter information before being changed by the parameter changing unit is read. Is read.

(Second Method) In a second method, an operator to which parameter information such as a tone color selection button or a style selection button is assigned is appropriately selected, and the selected parameter is selected by parameter changing means. When the operation of changing the parameter information assigned to the set operator is performed, the parameter changing means can be performed without performing a special operation such as an operation for determining the parameter information or a mode setting operation for writing the parameter information. At the same time as the parameter information is changed, the automatically changed parameter information is definitely assigned to the operator.

[0007]

However, in the first of the above-mentioned methods of assigning arbitrary parameter information to the operator, the changed parameter information is deterministically assigned to the operator. Since it is necessary to separately perform an operation for assignment, there is a problem that the operation is complicated and operability is poor.

On the other hand, in the second method of arbitrarily assigning parameter information to the operator, an operation for definitely assigning the changed parameter information to the operator is separately performed. Since there is no need to perform this operation, it is possible to definitively assign parameter information to operators with simple operations, but on the other hand, even if the operator erroneously changes the parameter information, There has been a problem that the parameter information is immediately and definitely assigned to the operator.

The present invention has been made in view of the above-mentioned various problems of the prior art, and has as its object to provide an instruction to start a performance after selecting parameter information. It is an object of the present invention to provide a parameter setting device that automatically and deterministically assigns the selected parameter information to the operator at the time.

[0010]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, parameter information is arbitrarily assigned to an operator, and the operator assigned the parameter information is assigned to the operator. When operated, the parameter setting device in which the parameter information assigned to the operator is supplied to a predetermined destination stores at least one or more operators for assigning parameter information and the parameter information assigned to the operator. Storage means, parameter setting means for setting desired parameter information to be allocated to the operation element, and parameter information being set in a state in which parameter information can be allocated according to the operation of the operation element, and the parameter information can be allocated When an instruction to start automatic performance including automatic accompaniment is given in a The parameter information set stored in the storage means it is obtained so as to have a assignment means for assigning parameter information to the operator. In the invention according to claim 2 of the present invention, when the parameter information is arbitrarily assigned to the operator and the operator assigned the parameter information is operated, the parameter information assigned to the operator becomes a predetermined value. In a parameter setting device supplied to a supply destination, at least one or more operators for allocating parameter information, and storage means for storing parameter information allocated to the operators.
A parameter setting means for setting desired parameter information to be assigned to the operation element; and a parameter setting section in which parameter information can be allocated in accordance with an operation of the operation element. When there is an instruction to start sounding, which is a timing at which parameter information is definitely assigned to the operator, the parameter information set by the parameter setting means is stored in the storage means, and the parameter information is stored in the operator. And an allocating means for allocating.

[0011]

According to the present invention, parameter information can be allocated in accordance with the operation of the operation element. When the performance start is instructed, the parameter information set by the parameter setting means is stored in the storage means. Parameter information is assigned to the operator.

[0012] For this reason, it is possible to automatically and steadily assign the parameter information to the operator when there is an instruction to start the performance, which is a preferable timing for definitely assigning the parameter information to the operator. Become like

In other words, setting the parameter information and instructing the start of the performance is interpreted as an intention of the operator to continue the performance based on the set parameter information. This is considered to be an extremely favorable timing for deterministic assignment.

The instruction to start the performance includes all instructions when the player attempts to start the performance.
For example, an instruction to start sounding the sound source by pressing a key on the keyboard,
An instruction to start sounding to a sound source by an external MIDI input, an instruction to start automatic performance including automatic accompaniment by pressing a start button for starting automatic performance including automatic accompaniment, and an automatic performance including automatic accompaniment And an instruction to start a synchronized performance by depressing a key to start the synchronized performance in a state where the synchronized performance of the keyboard and the performance by the keyboard can be performed.

To terminate the execution of the key release processing routine and return to the main routine.

As is clear from the above description of each routine, the performance start instruction flag is set to "1" when the key is pressed by the keyboard device 22 and when the automatic accompaniment is started by the automatic accompaniment device 26. Will be set to
With the performance start instruction flag set to “1”,
After the determination result of step S518 becomes affirmative and the performance start instruction flag is cleared (step S520), the tone color determination processing (step S524) is performed.
That is, when the keyboard device 22 is depressed, the automatic accompaniment device 2
6, when the automatic accompaniment is started, the tone number changed by the parameter change button 42 is automatically and definitely assigned to the currently selected tone color selection buttons 40-1 to 40-8. become.

The rhythm performance start instruction flag is set to "1" when the start button 52 is pressed and when the automatic accompaniment device 26 starts the automatic accompaniment in the synchro mode. However, when the rhythm performance start instruction flag is set to "1", the determination result in step S526 is affirmative, and after the rhythm performance start instruction flag is cleared (step S528), the style determination processing (step S532) is performed. Will be That is, when the start button 52 is pressed,
When the automatic accompaniment by the automatic accompaniment device 26 is started in the synchro mode, the style number changed by the parameter change button 48 is automatically added to the currently selected style selection buttons 46-1 to 46-8. And it will be assigned definitely.

On the other hand, even if the parameters are changed, if the performance start instruction is not given, the parameter information assigned to the operator will not be determined, so if the same operator is pressed again, the assignment will be performed first. The changed parameter information is copied to the temporary memory, and the state before the change can be returned. If it is cumbersome to press again a selected control with a large number of controls, a separate cancel switch with the same effect as the operation can be provided, eliminating the need to search for a switch and canceling the operation. Just press the switch to return to the state before the change.

As described above, rhythm start processing (step S1202) is performed in response to the start button 52 being pressed, and tone color determination processing (step S524) and style determination are performed in a later main routine. Since the performance start instruction flag and the rhythm performance start instruction flag for instructing the processing (step S532) are set (step S1206), the performance of the automatic accompaniment starts immediately when the start button 52 is pressed. After that, the timbre and style are determined. In this embodiment, the processing of the automatic accompaniment is performed not by the CPU 10 but by the automatic accompaniment device 26. However, if the CPU 10 also performs the processing of the automatic accompaniment, a large Although a load will be applied, by devising the processing as described above, when a large load is applied to the CPU 10 such as when automatic accompaniment is started, the tone / style is not determined, and when the load on the CPU 10 is reduced. , The automatic accompaniment performance is started without delay in response to the operation of the start button 52, and it is possible to prevent the automatic accompaniment from being sluggish. In this case, the timbre / style determination processing may be performed at the timing of beats and measures.

In the above embodiment, the tone number and the style number are taken as parameter information.
The tone color selection buttons 40-1 to 40-8 and the style selection buttons 46-1 to 46-8 are respectively assigned to the tone color selection buttons 40-1 to 40-8, but the parameter information is not limited to the parameter information relating to the tone color and the style as described above. Needless to say, the present invention can be applied to appropriate parameter information such as parameter information relating to effects such as reverb and chorus, parameter information relating to volume, and parameter information relating to the function of an operator.

In the above-described embodiment, when the key is depressed by the keyboard device 22 and when the automatic accompaniment device 26
When the automatic accompaniment is started, the tone number changed by the tone change button 42 is automatically assigned to the currently selected tone color selection buttons 40-1 to 40-8. When the start button 52 is pressed and when the automatic accompaniment device 26 starts the automatic accompaniment in the synchro mode, the currently selected style selection buttons 46-1 to 46-8.
Although the rhythm number changed by the rhythm change button 50 is automatically assigned to the above, it is limited to the sounding instruction to the sound source 24 and the instruction to start the automatic accompaniment to the automatic accompaniment device 26 as described above. Of course, the above-described determination processing of the parameter information may be automatically performed based on a sounding instruction to the sound source 24 input by MIDI or the like.

Further, in the above-described embodiment, even if the parameters (tone color parameters, style parameters) are changed during the rhythm performance (during automatic accompaniment), the changed parameters are applied to the button (tone color selection button 40-1). To 4
0-8, the style selection buttons 46-1 to 46-8) are not assigned to the buttons. However, even if the parameters are changed during the rhythm performance, the changed parameters may be assigned to the buttons. Good. For that purpose, the processing content shown in the above embodiment may be modified as follows, for example.

That is, it is determined whether or not a rhythm is being played in the tone parameter changing process. If the determination result is affirmative, a performance start instruction flag is set, and whether or not the rhythm is being played in the style / parameter changing process is determined. Judgment is made, and if the judgment result is affirmative, a rhythm performance start instruction flag is set. If the CPU 10 also performs the process of automatic accompaniment, the tone / style determination process may be performed at the timing of beats and measures.

Further, in the above-described embodiment,
Although the tone color number and the style number are assigned to the tone color selection buttons 40-1 to 40-8 and the style selection buttons 46-1 to 46-8, tone color data and style data may be assigned.

In the above embodiment, the case where the automatic accompaniment device 26 is provided as an example of the automatic performance device has been described. However, the present invention may be applied to the case where a normal automatic performance device is provided. Of course.
