Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance control device for controlling an automatic performance of an electronic musical instrument or the like.

[0002]

2. Description of the Related Art It has been known that an electronic musical instrument performs automatic performance according to a desired automatic performance pattern such as automatic rhythm performance or automatic bass chord performance. For example, in the case of Bossa Nova, a normal pattern and a variation pattern are prepared for a common rhythm name of Bossa Nova, and any one of the patterns can be selected and automatically played. Also,
The number of the variation patterns is not limited to one, but may be plural. Generally, such a performance pattern has a length of several measures, and by repeating this, a continuous automatic rhythm performance is performed.

In such a case, since the same pattern is repeated for the main performance pattern, the performance tends to be monotonous. Therefore, a sub-pattern called fill-in, break, ad-lib, or the like is prepared, and a performance according to this sub-pattern is temporarily inserted in response to an instruction by an artificial switch operation or the like, and then the process shifts to a main pattern. It has been done so.

There is known an automatic performance device which enables a variety of performances by temporarily inserting a fill-in pattern as described above (Japanese Patent Application Laid-Open No. Hei 4-305695). This automatic performance device includes, for example, two main patterns (a normal pattern and a variation pattern),
As the first and second fill-in patterns respectively corresponding to the main patterns, that is, as the fill-in pattern to be inserted during the performance of the normal pattern, N → N fill-in when transitioning from the normal pattern to the normal pattern, and from the normal pattern N → V fill-in when shifting to variation pattern,
As a fill-in pattern to be inserted during performance of a variation pattern, a V → V fill-in that shifts from a variation pattern to a variation pattern and a V → N fill-in that shifts from a variation pattern to a normal pattern are stored. In addition, it has two fill-in pattern selection switches “fill-in to normal” and “fill-in to variation” that are operated when switching between the two main patterns.

When the "fill-in to normal" switch is pressed during the normal pattern playing, the N → N fill-in pattern is inserted, and then the normal pattern is restored, and the "fill-in to variation" switch is turned on. When the button is pressed, the N → V fill-in pattern is inserted, and then the process shifts to a variation pattern. When the “fill-in to normal” switch is pressed during the variation pattern playing, the V → N fill-in pattern is inserted, and then the normal pattern is entered, and the “fill-in to variation” switch is pressed. Sometimes, the V → V fill-in pattern is inserted, and thereafter, the pattern is returned to the variation pattern.

[0006] Thus, the fill-in pattern corresponding to the main pattern being played and the main pattern to be transferred to is selected and inserted, so that the automatic performance is not monotonous. is there.

There is also known an automatic rhythm accompaniment apparatus which is configured to automatically insert a fill-in pattern when a performance pattern is switched without providing a switch for inserting a fill-in pattern as in the above-described example. (Japanese Patent Publication No. 60-28000).

[0008]

In the case of an automatic performance device provided with the above-mentioned fill-in pattern selection switch, it is possible to perform various performances, but both the fill-in pattern selection switch and the main pattern selection switch are provided. Therefore, there is a problem that the operation panel surface becomes complicated.

[0009] In the case of the above-mentioned configuration in which the fill-in pattern is automatically inserted, a clean operation panel surface can be provided because there is no need to provide a fill-in switch. When switching to a pattern, only a fill-in pattern can be inserted. Conversely, a performance pattern cannot be switched without inserting a fill-in pattern, and a variety of performances cannot be performed.

Therefore, according to the present invention, a fill-in pattern can be inserted not only when switching to another performance pattern but also when returning to the same performance pattern without increasing the number of operation switches. It is an object of the present invention to provide an automatic performance control device capable of performing various performances, which can switch to another performance pattern without inserting a fill-in pattern.

[0011]

In order to achieve the above object, an automatic performance control device according to the present invention comprises a performance pattern storage means for storing a plurality of main patterns and a plurality of fill-in patterns; A plurality of main pattern selection switches provided in correspondence with each other, and control means for controlling automatic performance based on the performance pattern, wherein when the main pattern selection switch is operated, the fill-in is performed in a first state. The performance is shifted to the performance of the selected main pattern without inserting the performance of the pattern. In the second state, the fill-in determined by the main pattern played immediately before and the selected main pattern is performed. After inserting the performance with the pattern, In which a control means for controlling to shift to play.

[0012] Further, there is further provided an operation mode setting means,
The first state and the second state in the control means are selected by the operation mode setting means. Further, the first and second states in the control means are selected according to an operation touch of the main pattern selection switch. Still further, the first and second control means may include
Is selected in accordance with the timing at which the main pattern selection switch is operated.

When the main pattern selection switch is operated, the operation of shifting to the performance of the selected main pattern without inserting the performance of the fill-in pattern, the main pattern played immediately before and the selected main pattern are performed. After the performance by the fill-in pattern determined by the pattern is inserted, the operation to shift to the performance by the selected main pattern can be switched, so that it is possible to select whether or not to insert the fill-in pattern. Becomes

The fill-in pattern to be inserted is
Since it is determined by the main pattern played immediately before and the selected main pattern, it is possible to avoid a monotonous performance. Further, since there is no need to provide a switch for selecting a fill-in pattern to be inserted, it is possible to prevent the operation panel surface from becoming complicated.

[0015]

FIG. 3 shows how the automatic performance pattern data is stored in the ROM 2. The ROM
2, a plurality of automatic performance patterns are stored for each rhythm. This figure shows one rhythm (for example,
This shows how automatic performance patterns corresponding to bossa nova are stored, for example, three main patterns, ie, three main patterns of main A, main B, and main C, and fill-in corresponding to each main pattern. A pattern group is stored.

That is, as the fill-in pattern inserted during the performance of the main A, the fill-in AA inserted between the main A and the main A, the fill-in AB inserted when shifting from the main A to the main B, and , And three types of fill-in AC inserted when shifting from the main A to the main C are stored. Further, as the fill-in pattern inserted during the performance of the main B, the fill-in BA inserted when shifting to the main A, the fill-in BB inserted between the main B and the main B, and shifting to the main C. The three fill-in patterns of fill-in BC that are sometimes inserted are stored.

Further, as a fill-in pattern inserted during performance of main C, fill-in CA inserted when shifting to main A, fill-in CB inserted when shifting to main B, and main C and main C
The three fill-in patterns of the fill-in CC inserted between the two are stored. As described above, in the illustrated example, a total of 12 automatic performance patterns of three main patterns and 3 × 3 = 9 fill-in patterns are stored. The ROM 2 also stores automatic performance patterns corresponding to other rhythms.

Each performance pattern is composed of a plurality of parts, such as rhythm, bass, and chord backing. In addition, the main pattern is one to several measures, generally two measures.
The fill-in pattern has a length shorter than that, typically one bar. Various formats of these performance patterns are known. For example, timing data and performance event data are stored in the order of addresses in the order of performance. Here, the timing data is data indicating a timing at which the performance event is to be generated.
The timing is data represented by the number of tempo clocks from the beginning of one bar to the occurrence of the event. The performance event data is note-on event data, and includes note number, velocity data, and the like.

A first embodiment of the automatic performance control device of the present invention thus configured will be described. As described above, in this embodiment, in addition to the main pattern selection switches 21 to 23 shown in FIG. 2 as switches for controlling automatic performance, whether or not a fill-in pattern is automatically inserted is determined. An auto-fill-in mode switch is provided for selecting whether or not. The player can operate the auto-fill-in mode switch to select an auto-fill-in mode or a normal mode in which no fill-in pattern is inserted.

FIG. 4 is a flowchart of a main pattern selection switch process executed when the main pattern selection switches 21 to 23 are operated in this embodiment. It should be noted that, in this figure, the case where the main A selection switch 21 is operated is shown as a representative,
The operation when the main B selection switch 22 or the main C selection switch 23 is operated is shown in parentheses in the figure.

The main pattern selection switch 2
Assuming that the main A selection switch 21 has been operated from among 1 to 23, first, in step S31, it is determined whether or not the current mode is the auto-fill-in mode. If the auto-fill-in mode switch is not turned on and the mode is the normal mode, the determination result is NO, and in step S36, a register NE for storing data designating a main pattern to be played next.
The selected main A is stored in XT, and the main pattern selection switch processing ends.

On the other hand, in the auto-fill-in mode in which the auto-fill-in mode switch is turned on, the result of the determination in step S31 is YES.
At this time, the process proceeds to step S32 to determine which performance pattern is currently being played. If the main A is being played at the time when the main A selection switch 21 is operated, the process proceeds to step S33 to immediately shift to the fill-in pattern AA. That is, the RO
The performance pattern read from M2 is changed from main A to fill-in AA. At this time, the performance of the fill-in AA is started from the middle of the bar. Next, the process proceeds to step S36, where the main A corresponding to the operated main pattern selection switch 21 is stored in the register NEXT for storing the performance pattern of the transition destination.

When the main A selection switch 21 is operated during the automatic performance of the main B, the result of the judgment in the step S32 becomes the main B and the step S34
Proceed to. Then, in step S34, the automatic performance pattern is immediately changed to fill-in BA, and
At 36, the main A is stored in the register NEXT. Thus, when the main A switch 21 is operated while the main B is being played, the main B is immediately shifted to the fill-in BA.

Further, when the main A selection switch 212 is operated during the automatic performance of the main C, the process proceeds to step S35, and the process proceeds to the fill-in CA, and the process proceeds to step S35.
At 36, the main A is stored in the register NEXT. As described above, when the main A selection switch 21 is operated during the performance of the main C, the process immediately shifts to the fill-in CA.

Further, the main A selection switch 2
When the operation of No. 1 is being performed during the performance of the fill-in pattern, the process proceeds to step S36, and the main A is stored in the register NEXT. That is, when the main pattern selection switches 21 to 23 are operated while the fill-in pattern is being played, only the process of rewriting the transition destination main pattern to the newly operated main pattern without changing the currently played fill-in pattern. I do.

FIG. 5 is a flowchart for explaining the automatic performance processing. This process is started by an interrupt for each tempo clock by the timer 4. When this processing is started, first, at step S41
Is performed from the corresponding area of the ROM 2 to reproduce the specified performance pattern.
Specifically, it is determined whether or not the timing is specified by the timing data in the performance pattern data. If the timing is to generate the event data, the event data is read from the ROM 2 and Send to circuit 10. Upon receiving the event data, the tone generator 10 generates a tone corresponding to the event data and outputs the tone to the effect circuit 11. The effect circuit 1
1 performs an effect process corresponding to the musical tone and outputs the result to the sound system 12, whereby a musical tone corresponding to the performance data is output. If the current timing is not the timing specified by the timing data, the process proceeds to step S42 without reading out the event data.

In step S42, it is determined whether or not the current timing is the timing of a bar line, that is, whether or not the current timing is the end of one bar. As a result, if the bar timing has not yet been reached, the automatic performance process is terminated. On the other hand, when it is the timing of a bar line, and the determination result is YES, the process proceeds to step S43.

In step S43, it is determined whether the pattern played so far is a fill-in pattern. If the result of this determination is YES, the operation proceeds to step S45, in which a transition is made to the pattern stored in the NEXT register (main A in the example shown in FIG. 4). That is, as the read address of the ROM 2, the main A
Set the address corresponding to. Thus, when the fill-in pattern is being played, the main pattern selected by the main pattern selection switches 21 to 23 is automatically played from the next bar.

If the performance pattern so far is the main pattern, the result of the determination in step S43 is NO, and the process proceeds to step S44. This step S4
In 4 the main pattern and NE
It is determined whether or not the main pattern stored in the XT register is the same. If the main pattern played so far is the same as the main pattern stored in the NEXT register, and the determination result is NO,
The automatic performance process is terminated. That is,
In the next bar, the same performance pattern is reproduced.

On the other hand, when the main pattern played so far does not match the main pattern stored in the NEXT register, the flow advances to step S45 to shift to the main pattern stored in the NEXT register. As a result, the main pattern stored in the NEXT register is played from the next bar. For example,
If the main pattern selection switch 21 is operated and the main A is selected when the main pattern played so far is the main B, the main A is played instead of the main B from the next bar. The Rukoto.

FIG. 6 shows how the performance pattern selected in each state according to the first embodiment of the present invention changes. First, in the normal mode in which the auto-fill-in mode switch is turned off, that is, when the determination result of step S31 in FIG.
In the case of, the operation result of the main pattern selection switch is stored in the NEXT register in the main pattern selection switch processing shown in FIG. Then, in the automatic performance process shown in FIG. 5, the determination result in step S43 becomes NO, and as shown in FIG. 6, the process shifts to the main pattern selected by the main pattern selection switch at the end of the bar line. . In this case, no fill-in pattern is inserted.

Next, when the auto-fill-in mode switch is turned on, the determination result of step S31 in FIG. 4 is YES, and as described above,
When the pattern being played is the main pattern, the process immediately shifts to the corresponding fill-in pattern without waiting for the end of the bar. The fill-in pattern transferred at this time is determined by the main pattern being played and the main pattern selected by the main pattern selection switch. That is, as shown in FIG. 6, when the main A is selected during the performance of the main A, the process shifts to the fill-in AA. When the main B is selected during the performance of the main A, the process shifts to the fill-in AB. Shift to the corresponding fill-in pattern. When the end of the bar has been reached, the program shifts to the selected main pattern as shown in the automatic performance processing of FIG. As described above, when the main pattern selection switch is operated during the playing of the main pattern, the operation immediately shifts to the corresponding fill-in pattern when the operation is detected, and shifts to the main pattern selected from the next bar. It will be.

When the main pattern selection switch is operated while the fill-in pattern is being played, the fill-in pattern being played is played until the end of the measure, and the main pattern is switched from the next measure. The operation shifts to the main pattern selected by the selection switch. For example, as shown in FIG. 6, when the main C is selected while the fill-in pattern AB is being played, the fill-in pattern AB is played until the end of the measure, and the main pattern C is started from the next measure.
Will be played.

Next, a second embodiment of the present invention will be described. In this embodiment, the same operation can be performed only by the main pattern selection switch without providing the above-described auto fill-in mode switch. In this embodiment, an operation touch detection type switch capable of detecting the intensity of operation of the main pattern selection switch is used. For example, a switch having two make contacts is used as the main pattern selection switch, and by detecting a time difference when both switches are turned on, the strength of the operation touch is identified.

FIG. 7 is a flowchart of the main pattern selection switch processing in the second embodiment. The automatic performance process is the same as that shown in FIG. The flowchart in FIG. 7 is the same as the processing flowchart in FIG. 4 except that step S31 in FIG. 4 is changed to step S51. In step S51, when the main pattern selection switches 21 to 23 are operated, it is determined whether the touch is strong or weak. When the determination result is strong, it is determined that the player intends to insert a fill-in pattern, as in the case of the auto-fill-in mode in FIG. 4, and the process proceeds to step S32.
On the other hand, when the operation touch of the main pattern selection switch is weak, it is determined that the player does not intend to insert a fill-in pattern, and as in the case of the normal mode shown in FIG. Proceed to step S36. The following processing is the same as that of the first embodiment described above, and the description is omitted.

FIG. 8 is a chart showing transitions of performance patterns in the second embodiment of the present invention. As shown in this chart, when the player operates any of the main pattern selection switches 21 to 23 with a weak touch, the process shifts to the main pattern operated from the next bar without inserting a fill-in pattern. When the player strongly operates any of the main pattern selection switches 21 to 23, the operation shifts to the corresponding fill-in pattern at the operation timing, and shifts to the operated main pattern from the next bar.

Further, when the player strongly operates the main pattern selection switches 21 to 23 during the performance of the fill-in pattern, the main bar shifts to the main bar from the next bar. Although not shown in FIG. 8, when the player weakly operates the main pattern selection switches 21 to 23 while playing the fill-in pattern, the process proceeds from step S51 to step S36 in FIG. Will shift to the main pattern from the next bar.

As described above, in the second embodiment, it is determined whether or not to insert a fill-in according to the strength of the player's operation of the main pattern selection switch without providing an auto-fill-in mode setting switch. Can be switched.

Next, a third embodiment of the automatic performance control device according to the present invention will be described with reference to the flowchart of FIG.
Will be described with reference to a chart showing the transition of the performance pattern.
In the third embodiment, whether or not to insert a fill-in pattern is determined according to the timing of the operation of the main pattern selection switch in one bar. This makes it possible to control whether or not to insert a fill-in pattern without providing an auto-fill-in mode setting switch and without providing a touch detection type switch as a main pattern selection switch.

FIG. 9 is a flowchart of the main pattern selection switch processing in the third embodiment. In this embodiment, the automatic performance process is the same as that in FIG.

In the flow chart of FIG. 9, step S32 in the flow chart shown in FIG.
The processing is the same as the main pattern selection switch processing of FIG. 4 except that the processing is changed to 61. This step S
61, the main pattern selection switch 21
23 are determined to be operated at a predetermined timing in the bar, for example, before the third beat. If the main pattern selection switches 21 to 23 are operated before the third beat, for example, it is determined that the player intends to insert a fill-in pattern, and the process proceeds to step S32. When the main pattern selection switches 21 to 23 are operated after a predetermined timing in a bar, the player intends to shift to the main pattern operated without inserting a fill-in pattern. The process proceeds to step S36.
Subsequent processing is the same as that of the first embodiment, and a description thereof will be omitted.

FIG. 10 is a chart showing transitions of performance patterns in the third embodiment. As shown in the figure, the performer selects the main pattern selection switches 21 to 21.
23 after a predetermined timing in the bar, that is,
When the operation is performed late, the control shifts from the next bar to the main pattern without inserting a fill-in pattern.

When the player operates the main pattern selection switches 21 to 23 earlier than a predetermined timing in a bar, that is, earlier when the player plays the main pattern, a corresponding operation is performed at the time of the operation. The process shifts to the fill-in pattern, and further shifts to the operated main pattern from the next bar. At this time, as the fill-in pattern to be inserted, a fill-in pattern corresponding to the main pattern being played and the selected main pattern is selected. Further, when the player operates the main pattern selection switches 21 to 23 while playing the fill-in pattern, the performance pattern is changed at that time even if the timing is before or after a predetermined timing. The next main bar does not move to the operated main pattern. In the example described above, the third
Although it has been determined whether or not the fill-in pattern is to be inserted based on the beat, the present invention is not limited to this, and another time position, for example, the fourth beat or the like can be used as a reference.

As described above, in this embodiment, the operation of the main pattern selection switch is not performed without providing the auto fill-in mode setting switch, and without providing the touch detection type switch as the main pattern selection switch. It is possible to control whether or not to insert a fill-in pattern according to the timing at which the fill-in pattern is inserted.

In the above description, the case where the main pattern has three types of main patterns of main A, main B and main C has been described as an example. However, the present invention is not limited to this. Or two types of main patterns. Also, three types of fill-in patterns (for example, fill-in A
A, fill-in AB, and fill-in AC) have been described, but some fill-in patterns may be shared as fill-in patterns when shifting to a different main pattern. For example, fill-in AB and fill-in A
C and a common pattern may be used.

Further, in the above-described embodiment, an example has been described in which, when the main pattern selection switch is operated during the performance of the main pattern, the operation is immediately shifted to the fill-in pattern. However, the present invention is not limited to this. A transition to the fill-in pattern may be made after a predetermined time after the operation of the pattern selection switch (for example, when the next beat timing arrives or when the next bar line timing arrives). Further, depending on whether the operation timing of the main pattern selection switch is the same timing within the bar, switching control is performed to immediately switch to the fill-in pattern or to switch to the fill-in pattern at the next bar line timing. You may. Furthermore, when switching the main pattern, it may be possible to select whether or not to insert a fill-in pattern.

Furthermore, in the above-described embodiment, the main pattern at the transition destination can be changed by operating the main pattern selection switch during the performance of the fill-in pattern. Alternatively, during the performance of the fill-in pattern, the operation of the main pattern selection switch may be invalidated. Furthermore, in the above description, the switching of the performance style has not been particularly described. However, the switching of the performance style during the reproduction may be performed by operating a style switching switch (not shown). In this case, a fill-in pattern may or may not be inserted when the performance style is switched. As the fill-in pattern to be inserted when the performance style is switched, a fill-in pattern belonging to the original performance style may be inserted, or a fill-in pattern belonging to the next performance style may be inserted.

Furthermore, in the above description, the case where the automatic performance control device of the present invention is applied to an electronic musical instrument has been described as an example. However, the automatic performance control device of the present invention is not limited to this. It may be in the form of an application program executed on a computer. In this case, the application program can be stored in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory and supplied to a personal computer, or can be supplied via a network. Furthermore, even in the case of an electronic musical instrument, the control program can be installed in the electronic musical instrument in the form of an upgraded version.

Furthermore, in the above-described embodiment, a description has been given of a keyboard instrument as an example.
It may be a wind instrument type, a percussion instrument type, or the like.
Furthermore, the present invention is not limited to an electronic musical instrument having a built-in automatic performance device, but may be separate devices and connected using communication means such as MIDI or various networks. Furthermore, the present invention can be applied to an automatic performance piano.

Further, in the above-described embodiment, the timing data included in the performance pattern data is represented by the absolute time within the bar, and the performance event is defined as a note-on event. However, the present invention is not limited to this. A method using timing data representing the time of occurrence of the performance event in terms of the time from the immediately preceding performance event, and performing with a note pitch and note length or a rest and rest length Any method such as a method of representing data, a method of securing a memory area for each minimum resolution of performance, and storing a performance event in a memory area corresponding to the time at which a performance event occurs may be used.
