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 automatic performance of an electronic musical instrument or the like.

[0002]

2. Description of the Related Art Conventionally, it has been known that an electronic musical instrument or the like performs an automatic performance according to a desired automatic performance pattern such as an automatic rhythm performance or an 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 one of the patterns can be selected and automatically played. Also,
The variation pattern is not limited to one, and a plurality of variation patterns may be prepared. 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 as the main performance pattern, the performance tends to be monotonous. Therefore, a sub-pattern called fill-in, break, ad-lib, etc. is prepared, a performance according to this sub-pattern is temporarily inserted according to an instruction by an artificial switch operation, and then the main pattern is entered. Is being done.

There is known an automatic performance device capable of performing various performances by temporarily inserting a fill-in pattern in this way (Japanese Patent Laid-Open No. 4-305695). This automatic performance device has, for example, two main patterns (a normal pattern and a variation pattern),
The first and second fill-in patterns corresponding to the respective main patterns, that is, the N-to-N fill-in at the time of transition from the normal pattern to the normal pattern and the normal pattern as the fill-in pattern to be inserted during the performance of the normal pattern N → V fill-in when shifting to a variation pattern,
As a fill-in pattern to be inserted during performance of the variation pattern, a V → V fill-in transition from the variation pattern to the variation pattern and a V → N fill-in transition from the variation pattern to the normal pattern are stored. Further, it has two fill-in pattern selection switches of "fill-in to normal" and "fill-in to variation" which are operated when switching between the two main patterns.

When the "fill-in to normal" switch is pressed during the performance of the normal pattern, the N-to-N fill-in pattern is inserted and then the normal pattern is restored, and the "fill-in to variation" switch is activated. When pressed, the N → V fill-in pattern is inserted, and then the variation pattern is entered. When the "fill-in to normal" switch is pressed during the variation pattern play, the V → N fill-in pattern is inserted, and then the normal pattern is entered, and the "fill-in to variation" switch is pressed. In some cases, the V → V fill-in pattern is inserted, and then the variation pattern is restored.

As a result, the fill-in pattern corresponding to the main pattern being played and the main pattern of the transition destination is selected and inserted, and the automatic performance can be prevented from becoming monotonous. is there.

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

[0008]

In the case of the automatic performance device provided with the fill-in pattern selection switch, it becomes 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.

Further, in the case of the above-mentioned one configured to automatically insert the fill-in pattern, it is not necessary to provide a fill-in switch, so that the operation panel surface can be made neat, but other performances are possible. A fill-in pattern can only be inserted when switching to a pattern, and conversely, a performance pattern cannot be switched without inserting a fill-in pattern, and a versatile performance cannot be performed.

Therefore, according to the present invention, the 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 a variety of 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 of the present invention includes a performance pattern storage means for storing a plurality of main patterns and a plurality of fill-in patterns, and the plurality of main patterns. A plurality of main pattern selection switches provided corresponding to each other, and a control means for controlling automatic performance by the performance pattern, wherein when the main pattern selection switch is operated, in the first state, the fill-in is performed. The performance of the selected main pattern is transferred without inserting the performance of the pattern, and in the second state, the fill-in determined by the main pattern that was being played immediately before and the selected main pattern. After inserting a performance with a pattern, In which a control means for controlling to shift to play.

Further, it further comprises an operation mode setting means,
The first and second states of the control means are selected by the operation mode setting means. Further, the first and second states of the control means are adapted to be selected according to the operation touch of the main pattern selection switch. Furthermore, the first and second control means
The state is selected according to the timing when 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 that was played immediately before, and the selected main pattern. After inserting the performance by the fill-in pattern determined by the pattern, it is possible to switch the operation to shift to the performance by the selected main pattern, so it is possible to select whether to insert the fill-in pattern. Becomes

The fill-in pattern to be inserted is
Since it is determined by the main pattern that was played immediately before and the selected main pattern, it is possible to avoid monotonous performance. Furthermore, since it is unnecessary to provide a switch for selecting the fill-in pattern to be inserted, it is possible to prevent the operation panel surface from becoming complicated.

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

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

Further, as a fill-in pattern to be inserted during the performance of the main C, a fill-in CA to be inserted at the time of transition to the main A, a fill-in CB to be inserted at the time of transition to the main B, and the main C and the main. C
Three fill-in patterns of fill-in CC inserted between and 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 as well.

Each performance pattern is composed of a plurality of parts such as rhythm, bass and chord backing. The main pattern is 1 to several measures, generally 2
The length is about 4 bars, and the fill-in pattern is shorter than that, usually 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 according to the order of performance. Here, the timing data is data indicating the timing at which the performance event should occur, and for example,
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 is composed of note numbers, velocity data, and the like.

A first embodiment of the automatic performance control device of the present invention thus constructed will be described. As described above, in this embodiment, as a switch for controlling the automatic performance, in addition to the main pattern selection switches 21 to 23 shown in FIG. 2, whether or not the fill-in pattern is automatically inserted is determined. An auto fill-in mode switch for selecting either is provided. The player can operate the auto fill-in mode switch to select the auto fill-in mode or the normal mode in which the fill-in pattern is not inserted.

FIG. 4 is a flow chart of the main pattern selection switch process executed when the main pattern selection switches 21 to 23 are operated in this embodiment. In addition, in this figure, the case where the main A selection switch 21 is operated is described 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 drawing.

Now, the main pattern selection switch 2
If the main A selection switch 21 among the items 1 to 23 is operated, first, in step S31, it is determined whether or not the current mode is the auto fill-in mode. When the auto fill-in mode switch is not in the ON state and is in the normal mode, the determination result is NO, and in step S36, the register NE for storing the data designating the main pattern to be played next is stored.
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 determination result in step S31 is YES.
In this case, the process goes to step S32 to determine which performance pattern is currently being played. If the main A is being played 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 will be started in the middle of the bar. Next, in step S36, the main A corresponding to the operated main pattern selection switch 21 is stored in the register NEXT which stores the performance pattern of the transfer destination.

When the main A selection switch 21 is operated during the automatic performance of main B, the result of the determination in step S32 is main B, and step S34
Proceed to. Then, in step S34, the automatic performance pattern is immediately changed to fill-in BA, and then in step S34.
At 36, the main A is stored in the register NEXT. As a result, when the main A switch 21 is operated while playing the main B, the main B is immediately switched 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 moves to fill-in CA, and step S
In 36, the main A is stored in the register NEXT. As described above, when the main A selection switch 21 is operated while playing the main C, the process immediately shifts to the fill-in CA.

Furthermore, the main A selection switch 2
When 1 is operated and the fill-in pattern is being played, 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 during the performance of the fill-in pattern, only the process of rewriting the main pattern of the transfer destination to the newly operated main pattern without changing the fill-in pattern being currently played. I do.

FIG. 5 is a flow chart for explaining the automatic performance process. This process is started by an interrupt for each tempo clock by the timer 4. When this process is activated, first, step S41
The performance pattern designated in 1 is read from the corresponding area of the ROM 2 and reproduced.
Specifically, it is determined whether or not it is the timing designated by the timing data in the performance pattern data, and when it is the timing at which the event data should be generated, the event data is read from the ROM 2 and the sound source is generated. It is sent to the circuit 10. Upon receiving this event data, the tone generator circuit 10 generates a corresponding musical sound and outputs it to the effect circuit 11. The effect circuit 1
No. 1 performs effect processing corresponding to the musical sound and outputs it to the sound system 12, whereby the musical sound corresponding to the performance data is output. When the current timing is not the timing designated by the timing data, the process proceeds to step S42 without reading 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 it is the end of one bar. As a result, if the bar line timing has not been reached yet, the automatic performance process is terminated. On the other hand, it is the timing of the bar line, and when this determination result is YES, the process proceeds to step S43.

In step S43, it is determined whether or not the pattern that has been played so far is a fill-in pattern. If the determination result is YES, the process proceeds to step S45 to shift to the pattern (main A in the example shown in FIG. 4) stored in the NEXT register. That is, as the read address of the ROM 2, the main A
Set the address corresponding to. As a result, 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.

When the performance pattern so far is the main pattern, the decision result in the step S43 becomes NO, and the routine advances to a step S44. This step S4
In 4, the main pattern and NE that I have been playing so far
It is determined whether the main pattern stored in the XT register is the same. If the main pattern that has been played so far and the main pattern stored in the NEXT register are the same, and the result of this determination is NO,
As it is, this automatic performance process is terminated. That is,
The same performance pattern is reproduced in the next measure.

On the other hand, when the main pattern that has been played so far does not match the main pattern stored in the NEXT register, the process proceeds to step S45, and the main pattern stored in the NEXT register is entered. As a result, the main pattern stored in the NEXT register is played from the next bar. For example,
If the main pattern that has been played so far is main B, and the main pattern selection switch 21 is operated to select main A, main A will be played instead of main B from the next measure. 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 off, that is, the determination result of step S31 in FIG. 4 is NO.
In this case, in the main pattern selection switch processing shown in FIG. 4, the operation result of the main pattern selection switch is stored in the NEXT register. Then, in the automatic performance process shown in FIG. 5, the decision result in the step S43 becomes NO, and as shown in FIG. 6, at the end of the bar line, the main pattern selection switch moves to the main pattern selected. . In this case, the fill-in pattern is not 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 main A is selected while playing main A, the process moves to fill-in AA, and when main B is selected while playing main A, the process moves to fill-in AB. Move to the corresponding fill-in pattern. When the end of the bar is reached, as shown in the automatic performance process of FIG. 5, the selected main pattern is entered. As described above, when the main pattern selection switch is operated during the performance of the main pattern, the operation immediately shifts to the corresponding fill-in pattern when the operation is detected, and the main pattern selected from the next bar is transitioned to. 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 that bar, and the main pattern starts from the next bar. The main pattern is selected by the selection switch. For example, as shown in FIG. 6, when the main C is selected while playing the fill-in pattern AB, the fill-in pattern AB is played until the end of the bar, and the main pattern C from the next bar.
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-mentioned auto fill-in mode switch. In this embodiment, as the main pattern selection switch, an operation touch detection type switch capable of detecting the operation strength of the switch is used. For example, a switch having two make contacts is used as the main pattern selection switch, and the strength of the operation touch is discriminated by detecting the time difference between both switches being turned on.

FIG. 7 is a flow chart 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 of FIG. 7 is the same as the processing flowchart of FIG. 4 except that step S31 in FIG. 4 is changed to step S51. This step S51 determines whether the touch was strong or weak when the main pattern selection switches 21 to 23 were operated. If the determination result is strong, it is assumed that the player intends to insert the 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 the fill-in pattern, and as in the case of the normal mode shown in FIG. It proceeds to step S36. The subsequent processing is the same as in the case of the above-described first embodiment, so description thereof will be omitted.

FIG. 8 is a chart showing the transition of the performance pattern in the second embodiment of the present invention. As shown in this chart, when the performer operates any of the main pattern selection switches 21 to 23 with a weak touch, the operation moves from the next bar to the operated main pattern without inserting the fill-in pattern. Further, when the performer strongly operates any of the main pattern selection switches 21 to 23, the fill-in pattern is shifted to the corresponding fill-in pattern at the operation timing, and the next measure is shifted to the operated main pattern.

Further, when the performer strongly operates the main pattern selection switches 21 to 23 during the performance of the fill-in pattern, the main pattern starts from the next measure. Further, although not shown in FIG. 8, when the performer 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 of FIG. , The next measure starts with the main pattern.

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

Next, regarding the third embodiment of the automatic performance control device of the present invention, the flowchart of FIG. 9 and FIG.
A description will be given with reference to the chart showing the transition of the performance pattern of.
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 performed within one bar. This makes it possible to control whether or not the fill-in pattern is inserted 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 flow chart of the main pattern selection switch process in the third embodiment. Also in this embodiment, the automatic performance process is the same as that shown in FIG.

In the flow chart of FIG. 9, step S32 in the flow chart shown in FIG.
It is the same as the main pattern selection switch process of FIG. 4 except that it is changed to 61. This step S
In 61, the main pattern selection switch 21
It is determined whether or not the characters # 23 to # 23 have been operated at a predetermined timing within the bar, for example, before the third beat. When the main pattern selection switches 21 to 23 are operated, for example, before the third beat, it is assumed that the performer intends to insert the fill-in pattern, and the process proceeds to step S32. Further, when the main pattern selection switches 21 to 23 are operated after a predetermined timing within a measure, the player intends to shift to the operated main pattern without inserting the fill-in pattern. , And proceeds to step S36.
The subsequent processing is the same as in the case of the above-described first embodiment, and thus the description thereof is omitted.

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

If the player operates the main pattern selection switches 21 to 23 before the predetermined timing within the measure, that is, earlier during the performance of the main pattern, the player responds at that time. The process moves to the fill-in pattern, and then to the operated main pattern from the next measure. 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. Furthermore, when the performer 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 the predetermined timing. Without changing, the operation moves from the next measure 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 it is possible to use another time position, such as the fourth beat, as a reference.

Thus, in this embodiment, the operation of the main pattern selection switch is 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 the fill-in pattern according to the timing.

In the above description, the case where the main pattern has three kinds of main patterns of main A, main B and main C has been described as an example, but the present invention is not limited to this, and for example, four kinds or more. It may have a main pattern or two types of main patterns. In addition, as the fill-in pattern, three types of fill-in patterns are provided for one main pattern (for example, fill-in A for main pattern A).
A, fill-in AB, fill-in AC) are shown, but some fill-in patterns may be shared as fill-in patterns when shifting to different main patterns. For example, fill-in AB and fill-in A
C and C may be a common pattern.

Further, in the above-mentioned embodiment, an example in which the fill-in pattern is immediately transferred when the main pattern selection switch is operated during the performance of the main pattern is shown, but the present invention is not limited to this. The fill-in pattern may be shifted to after a predetermined time (for example, when the next beat timing arrives or when the next bar line timing arrives) after the operation of the pattern selection switch. Further, depending on whether the operation timing of the main pattern selection switch is that timing within a bar, switching control is performed to immediately switch to the fill-in pattern or to the fill-in pattern at the next bar line timing. May be. Furthermore, it may be possible to select whether to insert the fill-in pattern when switching the main pattern.

Furthermore, in the above-described embodiment, the main pattern of the transfer destination can be changed by operating the main pattern selection switch during the performance of the fill-in pattern. Alternatively, the operation of the main pattern selection switch may be invalidated during the performance of the fill-in pattern. Furthermore, in the above description, the switching of the playing style was not particularly described, but the playing style may be switched during the reproduction by operating a style changeover switch (not shown). In that case, the fill-in pattern may or may not be inserted when the performance style is switched. Further, as the fill-in pattern to be inserted when switching the playing style, a fill-in pattern belonging to the original playing style may be inserted, or a fill-in pattern belonging to the next playing style may be inserted.

Furthermore, in the above, 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, but the automatic performance control device of the present invention is not limited to this, and for example, a personal computer can be used. 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, it can be installed in the electronic musical instrument in the form of a version upgrade of its control program.

Furthermore, in the above-mentioned embodiment, the keyboard musical instrument has been described as an example.
It may be a wind instrument type, a percussion instrument type, or the like.
Furthermore, the musical instruments are not limited to the electronic musical instruments having the built-in automatic performance device, but may be separate devices connected to each other by using communication means such as MIDI or various networks. Furthermore, it can be applied to an automatic piano as well.

Furthermore, in the above-described embodiment, the timing data included in the performance pattern data is represented by the absolute time within the measure at which the performance event occurs, and the performance event is a note-on event. , Not limited to this, a method that uses timing data that represents the time of occurrence of the performance event in terms of the time from the previous performance event, the note pitch and note length, or the rest and rest length. Any method such as a method of expressing data, a memory area for each minimum resolution of the performance, and a method of storing the performance event in a memory area corresponding to the time at which the performance event occurs may be used.

Furthermore, as the method of changing the tempo of automatic performance, there are a method of changing the cycle of the tempo clock, a method of correcting the value of the timing data while keeping the cycle of the tempo clock, and a timing data in one processing. Any method may be used, such as a method of changing the value for counting. Furthermore, the automatic performance data is
It may have a format in which the data of a plurality of channels are mixed, or may have a format in which the data of each channel is divided for each track.

Furthermore, various data such as a control program and performance pattern data can be stored in the hard disk device as the external storage device 13.
For example, when no control program or performance pattern data is stored in the ROM 2, the control program or performance pattern data is stored in the hard disk device and read into the RAM 3 so that the control program or performance pattern data is stored in the ROM 2. The operation can be performed in the same manner as when the performance pattern data is stored. In this case, it is possible to easily add a control program or performance pattern data, upgrade the version, and the like.
Further, a CD-ROM is further provided as the external storage device 13.
When the device is connected, the control program and various data stored therein can be read and stored in the hard disk device. This makes it possible to easily perform a new installation or version upgrade of the control program. The external storage device 13 is not limited to these, and a device for using various types of media such as a floppy disk device or a magneto-optical disk (MO) device can be connected as the external storage device 13.

Furthermore, the interface circuit 1
