DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device and a recording medium on which an automatic performance processing program is recorded.

[0002]

2. Description of the Related Art In an automatic performance, a specified performance pattern is read from a plurality of types of performance patterns stored in a memory and played. For example, when performing rhythm accompaniment data, in addition to a plurality of types of rhythm performance patterns, an intro to be played at the beginning of a song or a fill-in performance pattern to be inserted in the middle of a song is played as accompaniment data. . The performance pattern of the rhythm to be played can be freely selected by an operator such as a switch, and the performance can be switched from intro or fill-in performance to rhythm performance, or from rhythm performance to fill-in performance.

[0003]

However, in the conventional automatic performance, there is no flexibility in shifting from one performance pattern to another performance pattern. For example, when the switch for designating the rhythm is turned on during the performance of the intro, either the rhythm performance is switched to the designated rhythm performance immediately, or the rhythm performance is switched after the intro performance is completed. There was a problem that only one of them could be selected. For this reason, it has been proposed to newly add an operator such as a mode switch to enable any of the methods according to the mode. However, adding a switch is not only disadvantageous in terms of cost, miniaturization, and simplicity of operation, but also requires the user to remember which mode is currently in use. Will happen. An object of the present invention is to provide a method without adding a new operator.
The purpose of the present invention is to realize two modes for shifting from one performance pattern to another performance pattern by a simple operation.

[0004]

The automatic performance device according to the present invention corresponds to each of a plurality of types of first performance patterns and at least one type of second performance patterns, and responds to each operation. An operation element for designating a performance pattern; storage means for storing a type of performance pattern specified by the operated operation element; and an arbitrary type of first performance pattern during the performance of the second performance pattern. Pattern determining means for determining whether or not the type of the first performance pattern matches the type of the specified performance pattern stored in the storage means when the corresponding operator is operated; When it is determined by the pattern determining means that the types of the performance patterns match, the second performance pattern in the performance is stopped and the first performance pattern of the matching type is stopped. When the pattern discriminating means determines that the types of the performance patterns do not match, the type of the first performance pattern stored in the storage means is updated, and the first pattern during the performance is updated. After the performance of the second performance pattern is completed, a performance control means for starting the performance of the first performance pattern of the type corresponding to the operator operated during the performance of the second performance pattern is provided. I have.

In the recording medium according to the present invention, when an operation element corresponding to each of a plurality of types of first performance patterns and at least one type of second performance pattern is operated, the operation element corresponding to the operation element is operated. A pattern designating procedure for designating a performance pattern to be performed, a storage procedure for storing the type of the performance pattern designated by the pattern designating procedure in a predetermined storage means, and an arbitrary type of pattern during the performance of the second performance pattern. When an operation corresponding to the first performance pattern is performed, a pattern for determining whether or not the type of the first performance pattern matches the type of the specified performance pattern stored in the storage means. Determination procedure,
When it is determined by the pattern determination procedure that the types of the performance patterns match, the second performance pattern during the performance is stopped and the performance of the first performance pattern of the matching type is started, and When it is determined by the determination procedure that the types of the performance patterns do not match, the type of the first performance pattern stored in the storage means is updated, and after the performance of the second performance pattern during the performance is completed. A performance control procedure for starting performance of a first performance pattern of a type corresponding to an operation during performance of the second performance pattern, and an automatic performance processing program for executing the performance control procedure are recorded.

According to the present invention, when the first performance pattern is specified during the performance of the second performance pattern, it is determined whether or not the first performance pattern has been specified before. If it has been previously specified, the second performance pattern being played is stopped, and the performance immediately shifts to the performance of the specified first performance pattern. After the performance of the second performance pattern during the performance is completed, the process shifts to the performance of the specified first performance pattern.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an automatic performance device according to the present invention will be described with reference to the drawings. FIG. 1 shows the system configuration of the automatic performance device in the embodiment. C
PU1 is a switch unit 2, connected to the system bus,
Various commands and data are exchanged between the memory 3 and the sound system 4 to control the entire apparatus.

As shown in FIG. 2, the switch section 2 includes rhythm switches 21, 22, and 23, which are three operators for selecting a rhythm to be played, and an LED 21a as display means corresponding to each switch. , 22a and 23a. Further, an intro switch 24 as an operator for designating an intro performance and a fill-in switch 25 as an operator for designating a fill-in performance are provided, and LEDs 24a and 25a as display means corresponding to the respective switches are provided. In addition, a stop switch 26 is provided.

The memory 3 stores an automatic performance processing program executed by the CPU 1 and, as shown in FIG. 3A, accompaniment data of intros, fill-ins, rhythms 1, 2, and 3 which are accompaniment data of the automatic performance. Performance patterns are stored. Each piece of accompaniment data is composed of processing timing data (sound generation timing data) and timbre data for specifying a sound color to be sounded.

Further, the memory 3 is provided with various registers necessary for controlling the CPU 1, as shown in FIG. RN is a register that stores the currently specified rhythm pattern number. AF is a register for designating a performance mode.
"1" is an intro performance, "10" is a rhythm performance, "11"
Specifies the mode of fill-in performance. PA is shown in FIG.
This register stores the address of the accompaniment pattern shown in (1).

Although not shown, the sound system 4 includes a sound source including a waveform data ROM, a D / A converter,
It has a filter, an amplifier, and a speaker, and generates a sound based on a sounding instruction and musical sound data from the CPU 1.
The sound generation is stopped based on the mute instruction from.

Next, the operation of the automatic performance device in this embodiment will be described with reference to the flowchart of the CPU 1. FIG. 4 shows the main flow, after the initialization processing (step A1), the automatic performance processing (step A1).
2) A loop process for repeating other processes (step A3) is executed. In the initialization process, the rhythm 1 number is stored in the register RN, and the register AF is stored in the register RN.
Is set to “00 (stop)”, and the start address of the intro pattern is stored in the register PA.

FIG. 5 is a flow chart of the automatic performance process at step A2 in the main flow of FIG. In this process, it is determined whether or not the switch has been operated (step B).
1) When operated, the type of the operated switch is determined (step B2).

When the intro switch is operated, A
It is determined whether or not F is “00 (stop)”, and “00” is determined.
Is set to "01 (intro)" (step B4). Next, L corresponding to the operation switch
The ED is turned on (step B5). Therefore, in this case, the LED 24a is turned on. Then, the head address of the intro pattern corresponding to the operation switch is stored in PA (step B6). Thereafter, data processing for performing the intro pattern is performed (step B7). After the data processing, the process returns to the main flow in FIG.

If the AF is not "00" in step B3, that is, if a performance pattern is being played, the operation of the intro switch is invalid, and the process proceeds to step B7 to continue the data processing during the performance. I do.
After the data processing, the process returns to the main flow in FIG.

In step B2, if the operated switch is a rhythm switch, it is determined whether or not AF is "00 (stop)" (step B8). AF
Is "00", it is determined whether or not the rhythm pattern number of the RN is the same as the rhythm pattern number corresponding to the operation switch (step B9). If the numbers are different, the LED corresponding to RN is turned off (step B10), and the rhythm pattern number corresponding to the operation switch is stored in RN (step B11). next,
Flashes the LED corresponding to the operation switch (step B
12). In this case, the process returns to the main flow in FIG. 4 without playing the rhythm pattern corresponding to the operation switch. That is, if a rhythm pattern number different from the previously set rhythm pattern number is newly designated during stop, the designated rhythm pattern number is reserved and the LED is blinked, but no performance is performed. .

In step B9, if the rhythm pattern number of the RN and the rhythm pattern number corresponding to the operation switch are the same, AF is set to "10 (rhythm)" (step B13), and the contents of the RN are set. Is stored in PA (step B14). Also, the LED corresponding to the operation switch
Is turned on (step B15). This LED blinks before being turned on and is in a reserved state. Since this is the second operation, the state shifts from blinking (reservation) to lighting (performance). Therefore, the process shifts to step B7 to perform data processing of the accompaniment data of the rhythm pattern corresponding to the operation switch. After the data processing, the process returns to the main flow in FIG.

If it is determined in step B8 that the AF is not "00", it is determined whether or not the AF is "10 (rhythm)" (step B16). If it is not "10",
That is, when the intro or fill-in is being performed, it is determined whether or not the rhythm pattern number of the RN is the same as the rhythm pattern number corresponding to the operation switch (step B17). If the numbers are the same, that is, if a rhythm pattern number that has already been reserved and the LED is blinking is specified, the lit intro or fill-in LED is turned off (step B18).
Set AF to "10 (rhythm)" (step B1)
3) The head address of the rhythm pattern corresponding to the contents of the RN is stored in PA (step B14). The LED corresponding to the operation switch is turned on (step B1).
5). Then, the process shifts to step B7 to perform data processing of the accompaniment data of the rhythm pattern corresponding to the operation switch. After the data processing, the process returns to the main flow in FIG.

In this case, for example, when the rhythm switch is continuously operated during the intro or fill-in performance, the first operation makes a reservation, and the second operation shifts to performance. Therefore, the performance of the intro or fill-in is stopped, and the performance of the rhythm pattern corresponding to the operation switch is immediately started.

In step B17, if the rhythm pattern number of the RN is different from the rhythm pattern number corresponding to the operation switch, the LED corresponding to the RN is turned off (step B19), and the rhythm pattern number corresponding to the operation switch is changed. Store in the RN (step B20). Next, the LED corresponding to the operation switch blinks (step B21). Then, the process shifts to step B7 to perform data processing for continuing the performance of the intro or fill-in being performed. In this case, only the rhythm pattern corresponding to the operation switch is reserved, and the rhythm performance is not performed. After the data processing, the process returns to the main flow in FIG.

In step B16, AF is set to "10"
(Rhythm) ", it is determined whether or not the rhythm pattern number of the RN is the same as the rhythm pattern number corresponding to the operation switch (step B22). If the rhythm pattern numbers are different, the LED corresponding to the RN
Is turned off (step B23), and the rhythm pattern number corresponding to the operation switch is stored in the RN (step B2).
4). Next, the LED corresponding to the operation switch is turned on (step B25), and the head address of the rhythm pattern corresponding to the content of RN is stored in PA (step B2).
6). Then, the process shifts to step B7 to perform data processing of the accompaniment data of the rhythm pattern corresponding to the operation switch. After the data processing, the process returns to the main flow in FIG.

In step B22, when the rhythm pattern number of the RN is the same as the rhythm pattern number corresponding to the operation switch, the switch operation is invalidated, and the process proceeds to step B7, where the rhythm pattern corresponding to the contents of the RN is determined. Continue data processing. After the data processing, the process returns to the main flow in FIG. In this case, if the same rhythm pattern number as the currently playing rhythm pattern number is specified by a switch operation, the switch operation is not invalidated, and the rhythm pattern being played is played again from the start address. Is also good. In this case, from step B22 to step B26 (as indicated by the dotted line)
Transition.

In step B2, if the operated switch is a fill-in switch, AF is set to "10".
(Rhythm) ”(step B2).
7). If it is "10", the AF is set to "11 (fill-in)" (step B28), the LED corresponding to the operation switch is turned on (step B29), and the start address of the fill-in pattern corresponding to the operation switch is set. Is stored in the PA (step B30). And RN
Blinks the LED corresponding to the content of the step (step B3).
1). Next, the process proceeds to step B7 to perform data processing of the accompaniment data of the fill-in pattern corresponding to the operation switch. After the data processing, the process returns to the main flow in FIG. That is, when the fill-in switch is operated during performance of any rhythm pattern, the fill-in pattern is immediately played.

In step B27, AF is set to "10
(Rhythm) ”, AF is“ 00 (stop) ”
Is determined (step B32). If the AF is "11 (fill-in)", the switch operation is invalidated, and the flow shifts to step B7 to continue the data processing of the fill-in pattern. Even when the AF is "01 (intro)", the fill-in performance cannot be performed, so that the switch operation is invalidated, and the process proceeds to step B7 to continue the intro pattern data processing. In any case, after the data processing, the process returns to the main flow of FIG.
Also, when the AF is “00 (stop)”, since the fill-in performance to be inserted in the middle of the music is not performed, the switch operation is invalidated and the process returns to the main flow of FIG.

In step B2, if the operated switch is a stop switch, AF is set to "00".
(Stop) ”(step B3).
3). If it is not "00", AF is set to "00" (step B34), all the LEDs are turned off (step B35), and only the LED corresponding to the content of the RN blinks (step B36). Then, the process returns to the main flow of FIG. If the AF is “00” in step B33, the operation of the stop switch is invalid, and the process returns to the main flow in FIG.

If no switch operation is performed in step B1, it is determined whether or not AF is "00 (stop)" (step B37). If not "00",
That is, if any performance pattern is being played, the process proceeds to step B7 to continue the data processing of the accompaniment data being played. After the data processing, the process returns to the main flow in FIG. At step B37, AF is set to "00".
(Stop), the process returns to the main flow of FIG.

FIG. 6 is a flow chart of the data processing in step B7 in the automatic performance processing of FIG. In this process,
It is determined whether or not the current time has reached the processing timing (sound generation timing) of the accompaniment data (step C1). If the current time has not yet reached, the process immediately returns to the main flow in FIG. When the current time reaches the processing timing of the accompaniment data, the register PA is incremented (step C).
2) Advance the accompaniment data by one. Then, the accompaniment data corresponding to the PA is read out (step C3), and it is determined whether or not the read out accompaniment data is END (step C4).

If the accompaniment data is not END, the sound system 4 shown in FIG. 1 is instructed to produce a (percussion) sound corresponding to the timbre of the read accompaniment data (step C).
5). Then, PA is incremented and the next accompaniment data (processing timing data) is designated (step C).
6), returning to the main flow of FIG. Then, the process proceeds from the main flow to the flow of the automatic performance processing of FIG. 5, and every time the data processing is executed, steps C1 to C4 are executed to determine whether or not the read accompaniment data is END. If it is not END, in step C5, an instruction to sound the read accompaniment data is issued.

In step C4, if the read accompaniment data is END, it is determined whether or not AF is "10 (rhythm)" (step C7). AF
Is "01 (intro)" or "11 (fill-in)", the AF is set to "10" and the mode shifts to the rhythm performance mode (step C8), and the lit intro or fill-in LED is turned on. Turn off (Step C
9). Further, the LED corresponding to the content of the RN is turned on (step C10). Then, the head address of the rhythm pattern corresponding to the content of the RN is stored in PA (step C11), and the process proceeds to step C1 to determine whether or not the processing timing has been reached. That is, when the intro performance or the fill-in performance is completed, the processing shifts to the performance of the rhythm pattern specified by RN.

In step C7, if the AF is "10 (rhythm)", the performance is repeated, so that the process goes to step C11 to store the head address of the rhythm pattern corresponding to the contents of RN in PA. , Step C1
Then, it is determined whether or not the processing timing has been reached.

As described above, in the automatic performance device according to the above embodiment, a plurality of types of first performance patterns (rhythm patterns 1 to 3) and at least one type of second performance pattern
Corresponding to each of the performance patterns (intro and fill-in), and an operator (switch unit 2) for designating the corresponding performance pattern in accordance with the operation, and a type of the performance pattern specified by the operated operator (switch unit 2). Pattern number)
When an operator corresponding to an arbitrary type of first performance pattern is operated during the performance of the second performance pattern, the storage means (memory 3) for storing the first performance pattern A pattern discriminating means (pattern discriminating function of the CPU 1) for discriminating whether or not the type matches the type of the designated performance pattern stored in the storage means; When it is determined that the performance pattern has been played, the second performance pattern during the performance is stopped and the performance of the first performance pattern of the matched type is started. When it is determined, the type of the first performance pattern stored in the storage means is updated, and after the performance of the second performance pattern during the performance is completed, Performance control means for starting playing the corresponding type of first play pattern to the operated operator during a performance of the second performance patterns (CPU1 performance control functions)
, And is provided.

With the above arrangement, when the first performance pattern is designated during the performance of the second performance pattern, it is determined whether or not the first performance pattern has been designated before. If it is specified, the second performance pattern being played is stopped, and the process immediately proceeds to the performance of the specified first performance pattern. After the performance of the second performance pattern being performed is completed, the process shifts to the performance of the specified first performance pattern. Therefore, it is possible to realize two modes for shifting from one performance pattern to another performance pattern by a simple operation without adding a new operator.
