DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an automatic accompaniment apparatus for performing automatic accompaniment based on accompaniment style data including performance data, and more particularly to an automatic accompaniment apparatus for generating deformed accompaniment style data from accompaniment style data.

[0002]

2. Description of the Related Art Conventionally, in an automatic accompaniment apparatus, a large number of preset accompaniment style data (ie, existing accompaniment style data) can be transformed to create user-accompanied style data (modified accompaniment style data). There is something. In order to create the deformed accompaniment style data, there has been one that stores a set of transformation data corresponding to each accompaniment style data. Note that the time length of the transformation data is the same as or shorter than that of the existing accompaniment style data (usually one bar length).

[0003]

However, in a conventional automatic accompaniment apparatus, transformation data is provided for each accompaniment style data, and the accompaniment style data and the transformation data are processed as one set. Therefore, there are the following problems. For example, when creating two types of modified accompaniment style data from one existing accompaniment style data, the existing accompaniment style data is copied to a storage area (user style area) that can be used by the user, and the same existing accompaniment style data is created. Two sets of style data must be prepared, and the data amount is twice as large as one accompaniment style data. Furthermore, there are only three types of deformed accompaniment style data to be obtained: existing accompaniment style data, and first and second modified accompaniment style data. Even though the copied existing accompaniment style data occupies a storage area. There is a problem that it cannot be used effectively.

Further, the creation of long accompaniment style data in a long time leads to an increase in the amount of data, and as described above, the storage area cannot be used effectively. Therefore, in the conventional automatic accompaniment apparatus, only short accompaniment style data can be created. . For this reason, short accompaniment style data must be repeatedly reproduced during performance, and the accompaniment tends to be monotonous, making it difficult to obtain a variety of accompaniment.

An object of the present invention is to provide an automatic accompaniment apparatus capable of generating deformed accompaniment style data while suppressing an increase in the amount of data, enabling the generation of long accompaniment style data, and obtaining a variety of accompaniment. Make it an issue.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electronic musical instrument to which the present invention is applied. A CPU 1 controls the entire electronic musical instrument using a working area of a RAM 3 based on a control program stored in a ROM 2. During a performance, a key code, a key-on signal, and the like from the keyboard 4 are taken in via a detection circuit 4a, a tone signal is generated by a tone generator circuit 5, an effect is given by an effect circuit 6, and a sound system 7 generates a tone. Note that the tone generator circuit 5 is capable of substantially simultaneously generating a plurality of sounds by time division multiplexing processing of a plurality of channels, and enables ensemble performance of automatic accompaniment and keyboard performance of a plurality of parts. The keyboard 4 is not always necessary, and a key code, a key-on signal, and the like may be detected from within the panel switch.

At the time of automatic accompaniment, a chord is detected from a chord key range (for example, a left key range) of the keyboard 4 and accompaniment style data preset in the ROM 2 or accompaniment stored in the RAM 3 in accordance with the currently selected style. Reads style data and performs automatic accompaniment. At this time, RAM
3 or the transformation data stored in the hard disk or the like of the external storage device 9 is selected, the designated accompaniment style data is transformed based on the transformation data, and transformed accompaniment style data is generated. Automatic accompaniment is performed based on this.

The panel switch 8 is provided with various switches (not shown).
Is detected via the detection circuit 8a,
A process corresponding to an operation event of each switch is performed. The processing according to the operation event of the panel switch 8 includes processing for selecting a timbre for playing a keyboard, processing for starting / stopping an automatic accompaniment, saving modified accompaniment style data in the external storage device 9, saving modified data, and the like. Perform processing. Further, input processing of accompaniment style data or the like supplied from an external device via the interface 10 is performed.

The display circuit 11 includes, for example, a liquid crystal panel. The liquid crystal panel displays a screen switch and a cursor for a GUI, and moves the cursor by operating the panel switch 8, operates the screen switch, and so on. Of the accompaniment style data and transformation data, and input processing for giving a style name to the transformation data.

The timer 12 has a timing (for example, every 384th note) corresponding to the tempo information set by the CPU 1 and the resolution of the accompaniment data included in the accompaniment style data.
, An interrupt signal is generated, and the CPU 1 performs an interrupt process based on the interrupt signal to control automatic accompaniment.

In the following first to third embodiments, the actual processing of the deformation processing is described.
This is an example. FIG. 2 is a functional block diagram showing the configuration of the first embodiment. Each function is a function as storage means of the ROM 2, the RAM 3, and the external storage device 9, and the CPU 1 operates the RAM 2 based on a program stored in the ROM 2. This is realized by a function executed using an area. The accompaniment style data group 100 is a plurality of existing accompaniment style data preset in the ROM 2, existing accompaniment style data (usually custom style data) stored in the RAM 3 or the external storage device 9, and each accompaniment style data is For example, it includes performance data of a plurality of channels (CH1 to CHn) corresponding to a track of automatic accompaniment.

The transformation data group 200 includes, for example, data read from the external storage device 9 to the RAM 3 or R
This is data newly created on the AM3, and is one set or a plurality of sets (a plurality of sets in the figure).
One set of transformation data includes “style name” data that can be arbitrarily set by the user, and includes, for example, the following “revoice parameter”, “groove and dynamics parameter”, “drum replacement”, and the like. It is composed of various parameters and data as deformation instruction data, and “reference style” as style instruction data. (Revoice parameter) A parameter that determines an instruction to change the setting of the tone and the like for each track that constitutes the accompaniment data.
For example, it is composed of a voice number change, a volume change, a reverb, a chorus change, a pan change, and the like. (Groove and dynamics parameter) The groove parameter is a parameter for producing a subtle so-called "slip" (groove feeling) by making the velocity, time gate, and sound generation timing conform to certain rules. In order to set the groove parameters, a plurality of templates (groove templates) in which the rules of velocity, time gate, and sounding timing are determined in units of one measure or a plurality of measures are provided in advance as preset data. Select and set the template you want to use. Each parameter value in the selected and set groove template can be changed. The dynamics parameter is a parameter for dynamically changing the velocity intensity, as will be described later as an example. (Drum replacement) Drum replacement data is data for instructing replacement of a set drum tone, for example, data for instructing replacement of a snare of an original tone with a canberra of a new tone. (Reference style) The data of the reference style includes the existing accompaniment style data group 100 and the custom style data 50.
Data indicating the accompaniment style data to be transformed from 0.

The transformation process 300 is started by the start of the automatic accompaniment. The CPU 1 reads out the reference style data from the transformation data selected in the transformation data group 200, and acquires the accompaniment style data corresponding to the reference style data. From the accompaniment style data group 100,
The deformation is performed based on the various deformation instruction data of the deformation data. If the transformed accompaniment style data 400 is reproduced or the save is designated by operating the panel switch 8 or the like, the custom style data 500
As an external storage device 9 (for example, a hard disk).

The selection of the transformation data is specified by the liquid crystal panel of the display circuit 11.
The contents of the transformation data can be edited by input setting or the like on the liquid crystal panel, and a desired transformation process can be performed by editing the transformation data. When arbitrary style data is selected from the existing style data group 100 and automatic accompaniment is started, the automatic accompaniment is reproduced in the same manner as usual. Note that the automatic accompaniment can be reproduced based on the custom style data 500 saved in the external storage device 9, and furthermore, the custom style data 500 can be subjected to a deformation process. In this case, the “reference style” of the transformation data is data indicating the custom style data 500.

FIG. 3 is a diagram conceptually illustrating a modified example of the velocity by the dynamics parameter. As the original data (velocity data in the accompaniment style data), the maximum velocity value is set to “100”, and The case where the sound is “30”, the second sound is “100”, and the third to sixth sounds are “80”, “70”, “50”, and “40”. In this example, the velocity value is "100" when the velocity value is "101" or more, and is "1" when the velocity value is "0" or less.

The parameters to be set are a velocity reference value and a change rate. In this example, the velocity reference value = 5
0 and a case where the change rate is set to 0.5, and a case where the velocity reference value is 50 and the change rate is 1.5.
The change rate is a value of 1-2. The change value of the velocity value is the difference from the velocity reference value (each velocity value-
A velocity value after deformation is obtained by multiplying a change rate by the change rate, and adding the obtained change value to the reference value. Such velocity reference values and change rates are set in the transformation data as dynamics parameters, and the velocity values of the corresponding accompaniment style data are transformed.

FIG. 4 is a functional block diagram showing the configuration of the second embodiment. As in the first embodiment, the CPU 1, the ROM 2,
This is realized by the functions of the RAM 3, the external storage device 9, and the like.
Although the accompaniment style data group 100 is the same as that of the first embodiment, in the second embodiment, the time-series length of the selected transformation data of the transformation data group 200 is smaller than the length of the accompaniment style data. When the length is long, for example, this is applied when the number of measures to be transformed is specified and the number of measures is longer than the accompaniment style data.

That is, the transformation process 300 'is performed when the length specified by the transformation data is longer than the length of the accompaniment style data corresponding to the reference style, as shown by the box-shaped frame in FIG. When a series of transformations of the accompaniment style data are completed, the accompaniment style data is read out again to perform the transformation, and these are continuously reproduced. As a result, the deformed accompaniment style data 400 'that is longer than the accompaniment style data to be transformed is obtained. The modified accompaniment style data 400 'is also used as the custom style data 50'.
0 'can be saved in the external storage device 9.

FIG. 5 is a functional block diagram showing the configuration of the third embodiment. In the third embodiment, similarly to the first and second embodiments, the functions of the CPU 1, the ROM 2, the RAM 3, the external storage device 9 and the like are realized, and the accompaniment style data group 100 is also included in the first and second embodiments. Is the same as In the third embodiment, the data of the “reference style” of the transformation data 200 indicates a plurality of accompaniment style data, and the transformation processing 300 ″ transforms the plurality of accompaniment style data. For example, as shown in the figure, the accompaniment style data A is deformed twice consecutively, and then the accompaniment style data B is deformed once. As a result, the deformed accompaniment style data 400 ″ is obtained by combining a plurality of deformations of the accompaniment style data, and a long accompaniment style data that is rich in changes can be obtained. Note that this modified accompaniment style data 400 ″ is also
0 '' can be saved in the external storage device 9.

FIG. 6 is a diagram showing a display example of a liquid crystal panel in the display circuit 11 of the fourth embodiment. An existing accompaniment style selection operator (screen switch) 11a corresponding to existing accompaniment style data, and transformation data And a transformation data selection operator (screen switch) 11b for selecting. A preset style name or a style name set by the user is displayed corresponding to the existing accompaniment style selection operator 11a and the transformation data selection operator 11b, respectively. Then, by moving a cursor (for example, reverse display) to the existing accompaniment style selection operator 11a and operating a setting switch (not shown), the existing accompaniment style data is selected for automatic accompaniment, and the transformation data selection operator 11b is selected. When the cursor is moved to and the setting switch is operated, a menu box 11d is displayed as shown in the figure, and a mode is entered in which creation, editing, registration, and the like of deformation data are performed. It is to be noted that a known technique can be applied to perform various kinds of input processing and the like by operating the screen.

FIG. 7 shows the input / output in the embodiment of the present invention .
6 is a flowchart showing an operation in an accompaniment style mode for performing a setting process, the CPU corresponding to a screen operation of a liquid crystal panel and an operation of a panel switch 8 in a display circuit 11;
1 shows the processing of FIG.

The tail, in the fourth embodiment, has been to handle the deformation data as a "style" of one of the existing accompaniment style data and equal, this deformation for data is referred to as "toe Eek style".

First, When the accompaniment style mode is selected, style selection processing is performed in step S1. This process is a process of monitoring an operation input, and if another interrupt occurs when there is no operation input, the interrupt process is naturally performed. Next, when a style is selected, step S
In step 2, it is determined whether or not the selected style is the tweak style. If not, the existing accompaniment style data is selected, so that the playback processing and the like are performed in step S10 and the processing ends. I do.

In step S2, if the tweak style has been selected, it is determined in step S3 whether a new tweak style has been selected. If not, the process proceeds to step S7, where the new tweak style is selected. If it has been selected (designated), in step S4 tweak style data (deformation data) is created, and in step S5 it is determined whether or not storage is designated. If the save is not designated, the process proceeds to step S7. If the save is designated, the process of inputting the "style name" of the tweak style is performed in step S6, and the tweak style data is registered in the RAM 3 or the like, and the process proceeds to step S7. .

In step S7, the accompaniment style data corresponding to the "reference style" is modified in accordance with the instruction of the data in the tweak style to create modified accompaniment style data. Then, in step S8, it is determined whether or not the created modified accompaniment style data is designated to be saved. If the designated is to be saved, it is saved in the external storage device 9 or the like as custom style data in step S9. Proceed to S10. In step S10, a reproduction process or the like is performed based on the created deformed accompaniment style data, and the process ends.

By the above processing, designation and reproduction of existing accompaniment style data, creation, reproduction and saving of deformed accompaniment style data using transformation data (tweak style), and creation and registration of tweak style data can be performed. . The selection of the tweak style can be performed by the same operation as the selection of the existing accompaniment style data.

The accompaniment style data to be transformed may be data supplied from an external storage device such as an FD or a CD-ROM, in addition to the data preset in the ROM. The custom style data may be saved in the RAM once or in an external storage device.

In the above embodiment, the maximum velocity value of the dynamics parameter has been described as 100, but this numerical value may be any value. Also, the case where the change rate of the dynamics parameter is 0 to 2 has been described, but the upper limit and the lower limit of the change rate may be set to any number. The method of changing the velocity value by the dynamics parameter may be a method other than the embodiment, for example, a method of adding a value given as a parameter to each velocity value, or a method of multiplying each velocity value by a change rate given as a parameter. For example, another velocity value changing method may be used.

In the second and third embodiments, the long accompaniment style data is generated by repeatedly reading out the accompaniment style data for one modification data. The process of generating style data can be applied to the case of generating a deformed groove template from the groove template. For example, data for a deformed groove is created, a parameter value change instruction and a groove template to be referenced are set in the deformation data, and a previously given groove template is repeatedly read for a reference instruction time according to the reference instruction, and a parameter change instruction is issued. , The groove template given in advance is transformed to create a modified groove template. When there are a plurality of reference groove templates, the modification is performed in the same manner as in the third embodiment.
