[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rhythm playing device, and more particularly to a device having a function of creating a new rhythm pattern by combining bars selected from a plurality of different rhythm patterns stored in advance.

[0002]

2. Description of the Related Art Generally, an automatic rhythm playing device stores a plurality of rhythm patterns and plays a selected one of these rhythm patterns. These rhythm patterns are simple repetitions of one pattern. In order to avoid this, one rhythm pattern is composed of several measures, and each measure has a change, so that a more varied automatic rhythm performance is performed.

[0003] Recent automatic rhythm playing devices include:
The performance order of each rhythm pattern composed of a plurality of measures is stored in units of measures.
Assuming that there are two rhythm patterns, as shown in the table below, first, the first measure of A is stored, then the first and second measures of B are stored, and then the first to third measures of A are stored. In some cases, the first and second measures of B are stored again, and a rhythm pattern is played based on this storage.

[0004]

[0005]

However, as is apparent from the above table, in the conventional automatic rhythm playing device, when the pattern name is changed, the first of the changed pattern is always required.
Since the measures are stored, the first measure is played even though it is not the first measure in the actual performance. For example, the first measure is played in the actual second, fourth, and seventh measures, respectively. Therefore, there is a problem that the connection of patterns becomes discontinuous.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic rhythm playing device configured to connect each measure continuously when a new rhythm pattern is created by combining a plurality of rhythm patterns. .

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 uses a normal rhythm pattern having a rhythm name and performance data of a plurality of measures as shown in FIG. Rhythm pattern storage means 2 for storing a plurality of normal rhythm patterns, rhythm pattern name input means 6 for designating the pattern names of the respective rhythm patterns in the order of performance, and pattern names input by the rhythm pattern name input means Each time the number of measures is increased from the initial value to 1
A bar number setting means 8 for setting the bar number to a larger value at a time, and inputting the rhythm pattern name and the bar number set
When the rhythm pattern corresponding to the input pattern name is an unusual rhythm pattern, after the storage in the storage unit is completed,
Changing means 12 for changing the measure number of the measure number setting means to the initial value.

[0008]

[0009]

According to the first aspect of the present invention, when the pattern names to be used are input in the order of use by the pattern name input means 6, the number of measures set by the measure number setting means 8 is also sequentially set to the initial value. From one by one. Therefore, for example, when the pattern A of the normal pattern is specified first, the number of measures is an initial value, for example, 1. When the pattern B of the normal pattern is specified next, the number of measures is 2 instead of 1. . Therefore, the song data in which the unnaturalness of the connection of the rhythm pattern has been eliminated is stored in the storage means. The rhythm pattern storage means 2 stores an unusual pattern such as an intro in addition to a normal rhythm pattern. For example, if the second measure of the pattern A is stored after the first measure of the intro, it becomes unnatural when played. Therefore, in order to set the number of measures of the pattern stored after the non-normal pattern is stored as the first measure, for example, when an intro is stored, the first measure of the normal pattern is stored next. Is designated and stored in the storage means 10, the change means 12 changes the measure number of the measure number setting means 8 to the initial value.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS.
1 shows a music playing device . Automatic rhythm performance apparatus this has a sound source unit 20 as shown in FIG. 2, the sound source unit 20 comprises a CPU
A rhythm is generated based on the control data from 22. The rhythm generated by the sound source section 20 is supplied to an amplifier 24 and is amplified. The CPU 22 generates the sound source unit 20 based on the rhythm patterns stored in the RAM 26 or a song created based on these rhythm patterns.
Create a rhythm.

The rhythm patterns stored in the RAM 26 are, for example, four variation patterns ROCK-1V1 to ROCK-1V4, ROCK-V with respect to the original rhythm patterns of ROCK-1 to ROCK-3.
2V1 to ROCK-2V4, ROCK-3V1 to R
It consists of a normal pattern consisting of OCK-3V4 and non-normal patterns such as intro, fill-in, break, and ending. In addition, even if these unusual patterns are the same pattern, for example, the same intro, a plurality of types such as intro 1 and intro 2 are stored. FIG.
Shows a state in which these rhythm patterns are stored in the RAM 26. Each rhythm pattern has a rhythm pattern name at the beginning, as shown in the enlarged view on the right side of FIG. A plurality of sets of bar data indicating the number of bars in each bar and performance data indicating the tone generation timing of each musical tone in the bar are stored. In this embodiment, each normal rhythm pattern is composed of four measures. These RAM
When the rhythm pattern stored in the rhythm pattern 26 is to be played as it is, a pattern selection switch 28a of the operator group 28 shown in FIG. You only have to operate the one you want to play. By this operation, the CPU 2
2 reads out the rhythm pattern corresponding to the operated pattern selection switch 28a from the RAM 26, and
Supply 0.

The automatic rhythm playing device has a function of creating a new rhythm pattern by combining specific measures of specified ones among the above rhythm patterns, ie, a song function. The song function stores the rhythm pattern name constituting the newly created rhythm pattern (song) and the measure data of the measure to be played by the rhythm pattern in the RAM 26 in the order of performance. Can be created in a predetermined number.

To create a song, the user operates the song edit switch 28i shown in FIG. At this time, since the song name is displayed on the display unit 30 as shown in FIG. 4, the + switch 28e and the-switch 28d are operated to display the song name for which a new song is to be set. As a result, a new song can be set to the displayed song name. If a song has already been set for the selected song name, this means that the display section 30 displays 001 indicating the first measure and the rhythm pattern name of the first measure of the song. Then, the delete switch 28b is operated to delete the contents of the song name. If no song has been set for the song name, a display indicating the first measure is performed, but the rhythm pattern name is not displayed.

When the pattern select switch 28a corresponding to the rhythm pattern to be written in the first measure of the song name is operated, the measure data representing the first measure of the rhythm pattern is stored in the RAM 26. Subsequently, the display indicating the bar on the display unit 30 changes to 002. When the pattern selection switch 28a corresponding to the rhythm pattern to be written in the second bar is operated, the bar data indicating the second bar of the rhythm pattern is displayed. Is stored. Hereinafter, the rhythm pattern name of each bar and its bar data are stored in order in the same manner.

Next, a state in which a song is written as described above will be described with reference to FIGS. CPU
In FIG. 22, three registers PN, PM, and BC are provided for writing such a song, as shown in FIG. The register PN is for counting how many bars of the song are to be written, the register PM is for storing a rhythm pattern name to be written, and the register BC is for register PM.
What measure of the rhythm pattern is stored in RAM2
6 to store the data to be written.

As shown in FIG. 6, when the song editing mode is set, initialization is performed, and as a result, registers PN and BC are set.
Are set to 1 (step S2). Then, it is determined whether a pattern has been designated, that is, whether one of the rhythm pattern selection switches 28a has been operated (step S4). If the answer to this step S2 is yes,
The pattern name corresponding to the operated pattern selection switch 28a is written to the register PM (step S).
6). Next, the values of the registers PN, PM, and BC are stored in RAM2.
6 (step S8). And the next R
Registers PN and BC as preparation for writing to AM 26
Are increased by 1 (steps S9, S9,
0), it is determined whether the value of the register BC is 5 (step S12). Since each rhythm pattern is composed of four measures, it is meaningless to write the fifth measure of the rhythm pattern stored in the register PM. (When step S12 is YES), the register BC
Is changed to 1 (step S14), and the process returns to step S4. If the value of the register BC is not 5 (No in step S12), the process directly returns to step S4 because there is no need to change the value of the register BC. Then, similarly, the pattern name and the number of measures of each measure are written in the RAM. If no pattern is specified in step S4 (No in step S4), it is determined whether or not the editing is completed (step S16). That is, it is determined whether the song edit switch 28i has been operated again. If the answer is no, the process returns to step S4, and if the answer is yes, the song editing mode is ended.

FIG. 5 shows a state in which the contents of the registers PN, PM, and BC change according to the song editing mode. FIG. 7 shows the state of the registers PN, PM, and BC.
Shows the contents of the song written in the RAM 26 in accordance with the contents of the register 26. As apparent from the comparison, the value of the register BC is automatically advanced by one. , First
The first measure of ROCK-1V2 is played in the measure, the second measure of ROCK-1V2 is played in the second measure,
The third measure of ROCK-1V1 is played in the third measure. Therefore, the connection between the rhythm patterns does not become unnatural. When the value of the register BC becomes 5, this is changed to 1, so that the first measure of the ROCK-1V1 is played again at the fifth measure.

FIGS. 8 and 9 show one embodiment of the present invention .
As is apparent from the contents of the song stored in the RAM 26 shown in FIG. 8, this embodiment is for creating a song including an unusual pattern such as an intro or fill-in in addition to a normal pattern. If, for example, ROCK-1V1 is specified next to the intro in the first embodiment, the second measure of ROCK-1V1 is stored in the RAM 26, and the connection becomes unnatural. Therefore,
As shown in FIG. 8, the normal pattern specified next to the intro or fill-in is configured so that the first measure is specified. In this embodiment, each of the non-normal patterns such as an intro and a fill-in is composed of one bar.

As described above, since the unusual pattern is composed of one bar, as a result of the processing in steps S4, S6 and S8, if the pattern name is an unusual pattern, the value of the register BC Is other than 1,
Since the pattern name is an unusual pattern, when an actual performance is performed, the unusual pattern is played. A step S22 is provided between step S10 and step S12 to determine whether the pattern name already stored in the register PM is a normal pattern. If the answer to this step S22 is NO, step S14 is executed. Then, the value of the register BC is set to 1. As a result, after the non-normal pattern is written, the value of the register BC always becomes 1, and when the normal pattern is written to the RAM 26 next, the first bar of the normal pattern is written. If the answer to step S22 is yes, the processing of the normal pattern after step S12 is performed.

In the flowcharts of FIGS. 6 and 9, the display processing on the display unit 30 is omitted for the sake of simplicity, but actually, the processing for display on the display unit 30 is omitted. Done. Further, in each of the above-described embodiments, the normal pattern is composed of four measures. However, the present invention is not limited to this. The number of measures of each normal pattern can be arbitrarily changed according to the situation.

[0022]

As described above, according to the first aspect of the present invention, when the normal pattern names to be used are designated in the order of use by the pattern name input means 6, the measure number setting means 8 Since the number of measures to be specified also increases one by one from the initial value, these pattern name specification means 6
In the song data created based on and the measure number setting means 8, the unnatural connection in each measure is eliminated.
Further, after the unusual pattern is designated and stored in the storage means 10, the changing means 12 changes the number of measures of the measure number setting means 8 to an initial value. Even when storing song data including an unusual pattern, the unnaturalness at the connection between the unusual pattern and the normal pattern is eliminated.
