Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device which automatically mutes a specific part among a plurality of parts.

[0002]

2. Description of the Related Art Conventionally, there has been known an automatic performance device for automatically playing a plurality of parts such as a rhythm part, a chord part, a bass part or a melody part at the same time. In such an automatic performance device, a part selection switch for designating whether to reproduce or mute the musical sound of the part is provided for each part. The part selected by the part selection switch is hereinafter referred to as "trigger part". Here, as a method of muting, a method of completely stopping the sound generation, a method of reducing the volume, and the like are known.

In such an automatic performance device, the performer sets the tempo of the automatic performance to a desired tempo and operates the part selection switch to determine the trigger part.
Then, the performer can play the trigger part, for example, on the keyboard while listening to the musical sounds of the parts other than the unmuted trigger part. For example, by muting the melody part and causing the rhythm part, the chord part, and the bass part to sound, it is possible to play the melody in accordance with the accompaniment sound composed of the rhythm, the chord, and the bass.

[0004]

However, for example, when the performer practices a melody, the melody part is muted. Therefore, when the player wants to hear the melody stored as the automatic performance data as a model, the part selection switch is operated. Then I had to unmute and have all parts play automatically. The same applies to other parts. Such an operation is not only troublesome, but there is also a problem that it is not possible to practice it effectively because it cannot be directly compared with the model.

The present invention has been made in view of the above circumstances, and is an automatic performance excellent in operability that enables effective practice while comparing the original musical sound of a predetermined part with the musical sound played by the player. The purpose is to provide a device.

[0006]

According to a first aspect of the present invention, in order to achieve the above object, an automatic performance device for automatically performing a musical sound by simultaneously generating a plurality of musical tones is provided. Selecting means for selecting a specific part from the above, start instructing means for instructing the start of automatic performance, and a unit of a predetermined length of the specific part selected by the selecting means in response to the instruction of the start instructing means. It is characterized in that it is provided with control means for continuously producing sound and non-sound for a section.

According to a second aspect of the present invention, for the same purpose as described above, in an automatic performance device for automatically performing performance by simultaneously generating musical sounds of a plurality of parts, selection for selecting a specific part from the plurality of parts is performed. Means, a section setting means for setting a repeat section for repeating the automatic performance, a start instruction means for instructing the start of the automatic performance, and a specific part selected by the selecting means in response to the instruction of the start instruction means. It is characterized by further comprising: control means for continuously producing and not producing sound for the repeat section set by the section setting means.

[0008]

According to the first aspect of the invention, in an automatic performance device for automatically performing a musical sound by simultaneously generating musical sounds of a plurality of parts, a specific part selected from the plurality of parts is of a predetermined length. The pronunciation and non-pronouncing are continuously performed for the unit section of.

As the unit section, 1 bar, 2 bars,
..., several bars, all bars, etc. can be arbitrarily determined in advance. Further, the unit section is not limited to one place in an automatic performance song (hereinafter, simply referred to as "song"), but may be set in advance in a plurality of discrete places in the song or a plurality of consecutive places throughout the song. For example, when the unit section is defined as one bar over the entire song and a melody part is selected as a trigger part, an automatic performance that includes a melody for each one bar and an automatic performance that does not include a melody. And are done. Then, when the automatic performance of a predetermined one bar ends, the automatic performance of the next one bar proceeds, and so on.

Therefore, the player can practice the music by listening to the automatic performance including the melody for each measure as a model for the first time and playing the melody himself for the second time while listening and comparing. If another part such as a chord part, a bass part or a rhythm part is selected as the specific part, it is possible to practice while listening to the model of each part in the same manner as above. As described above, since it is possible to practice while listening and comparing the original musical sound of the specific part and the musical sound played by the player, there is an advantage that effective training can be performed.

According to a second aspect of the present invention, in an automatic performance device for automatically performing a musical sound by simultaneously generating musical sounds of a plurality of parts, the interval setting means of a specific part selected from the plurality of parts is set. Sound generation and non-sound generation are continuously performed for the repeat section, and this sound generation and non-sound generation are repeated as one set.

A plurality of repeat sections can be set. For example, when only one repeat section is set and a melody part is selected as a specific part, the repeat section is divided into an automatic performance including a melody and an automatic performance including no melody. Is repeated twice, and this is repeated to perform automatic performance.

Further, if means for setting the number of repetitions of the repeat section is further provided, it is possible to shift to the automatic performance of the next section when the set number of times ends. In this case, if a plurality of repeat sections are set, the automatic performance can be configured to proceed while repeating a desired section a predetermined number of times.

As described above, according to the present invention, since it is possible to practice repeatedly while listening to the model of the desired section, more effective practice is possible.

The play / stop switch 131 corresponds to the start instruction means, and is constituted by a push button switch, for example. The play / stop switch 131 is used by the performer to control the start or stop of the automatic performance. The setting state of the play / stop switch 131 is stored by a play flag provided in the RAM 12. Play / stop switch 131 when the automatic performance is stopped (stopped), that is, when the play flag is "0".
When is pressed, the play flag is set to "1" and the automatic performance is started. On the other hand, when the play / stop switch 131 is pressed during automatic performance (during play), that is, when the play flag is "1", the play flag is cleared to "0" and the automatic performance is stopped.

The mode switch 132 is composed of, for example, a push button switch. This mode switch 132 is
Used to specify whether to operate in special mode. Here, the special mode refers to an operation mode in which the automatic performance is advanced while repeating each unit section of the trigger part twice each of sounding (first time) and non-sounding (second time). Here, the unit section means a section having a predetermined length which is predetermined as a unit (length) in which the automatic performance is repeated between sounding and non-sounding. The setting state of the mode switch 132 is R
It is stored by the mode flag provided in the AM 12.
When the mode switch 132 is pressed while the automatic musical instrument is in the normal mode (mode flag = 0), the mode flag is set to "1" and the mode is shifted to the special mode. When the special mode (mode flag = 1) When the mode switch 132 is pressed, the mode flag is cleared to "0" and the mode is shifted to the normal mode.

The part selection switch 133 is a switch used to select a trigger part, and is composed of, for example, a push button switch. This part selection switch 1
Reference numeral 33 corresponds to selection means. This part selection switch 1
Every time 33 is pressed, the part number is incremented,

→ Trigger part is selected by sequentially cycling through "bass part" → "melody part" → "rhythm part" → ...

The music selection switch 134 is a switch used to select a music piece to be automatically played, and is composed of, for example, a push button switch. Each time the song selection switch 134 is pressed, the song number is incremented and the ROM 11
The songs (automatic performance data) corresponding to the song numbers stored in are sequentially circulated and selected.

Although the push-button switch is used as each of the above-mentioned switches, various switches other than this, for example, various switches such as a touch switch and a pointing device which can generate an on event can be used. Further, as the part selection switch 133 or the music selection switch 134, for example, a ten key, a dial or the like which can directly input the part number or the song number can be used instead of the push button switch.

The display 130 is used to display various messages. As the display device 130, for example, an LCD display device, an LED display device or the like can be used.
This display has an automatic performance state (discrimination between playing and stopped) set by pressing the play / stop switch 131, a current mode (normal mode or special mode) set by pressing the mode switch 132, The name of the trigger part selected by the part selection switch 133, the name of the song selected by the song selection switch 134, and various other messages are displayed.

In addition to the above, the operation panel 13 is provided with various switches and indicators, such as a tone color selection switch, a sound effect designation switch, a volume switch, and an LED indicator corresponding to these switches. Since it is not directly related to the present invention, illustration and description thereof will be omitted.

The operation panel 13 includes the main operation panel 1
3 includes a panel interface circuit (not shown) for controlling data transmission / reception between the CPU 3 and the CPU 10. The panel interface circuit scans each switch according to a scan command from the CPU 10. The signal indicating the open / closed state of each switch obtained by this scan (hereinafter referred to as “panel data”) is composed of a bit string corresponding to each switch and is sent to the CPU 10 via the system bus 20. This panel data is used to determine whether an on or off event of a switch on the operation panel 13 has occurred (details will be described later).

The panel interface circuit is CP
The display data sent from U10 is sent to the display device 130. As a result, a message in accordance with, for example, character data sent from the CPU 10 is displayed on the display device 130, and an LED display device (not shown) is turned on.

Next, the operation of the automatic musical instrument having the above-mentioned structure will be described with reference to the flow charts shown in FIGS. The operations shown in the above flow charts are all realized by the processing of the CPU 10.

(1) Main Processing FIG. 3A is a flow chart showing the main routine of the present automatic performance device, which is started by turning on the power. When the power is turned on, first, initialization processing is performed (step S10). In this initialization processing, the internal hardware of the CPU 10 is set to the initial state, and the RAM is
The registers, counters, flags, etc. defined in 12 are set to the initial state. Also, in this initialization processing, processing is performed to prevent generation of unnecessary sound when power is turned on by sending predetermined data to the sound source 17. Further, in this initialization processing, various I
The / O port is also initialized.

Upon completion of this initialization processing, panel processing is then carried out (step S11). In this panel processing, processing corresponding to the operation of each switch of the operation panel 13 is performed. Details of this panel processing will be described later.

Next, automatic performance processing is performed (step S12). In this automatic performance process, during play, a process of producing a sound based on the automatic performance data stored in the ROM 11 is performed. Details of this automatic performance process will be described later.

Next, external input data processing is performed (step S13). In this external input data processing, processing according to the data input from the external interface 14 is performed. For example, the external interface 14 is MI
In the case of the DI interface, when note-on or note-off data is input, sounding or mute processing is performed, and when a control change message is input, processing similar to panel processing described later is performed.

After that, the process returns to step S11, and the processes of steps S11 to S13 are repeated. In the process of repeated execution, an event based on panel operation occurs,
Alternatively, when data is input from the external interface 14, processing corresponding to the data is performed, and sound generation processing based on the automatic performance data is performed to realize various functions as an automatic performance device.

(2) Timer Interrupt Processing The timer interrupt processing is performed by interrupting each processing of the main routine according to an interrupt signal generated from a timer built in the CPU 10.

In this timer interrupt process, clock increment is performed (step S15). That is, RAM
The contents of the clock counter provided in 12 are incremented. The contents of the clock counter are referred to in the automatic performance processing described later and are used to determine whether or not the timing for determining whether or not to perform the sound generation processing (hereinafter referred to as "sound generation processing timing") has arrived. . This sound generation processing timing is also used as the timing for decrementing the gate time that determines the sound length during sound generation.

When this clock increment processing is completed, the routine returns from this timer interrupt processing routine,
Return to the interrupted position in the main routine.

(3) Panel Processing Next, the details of the panel processing performed in step S11 of the main routine will be described with reference to the flowchart of FIG.

In the panel processing, first, panel data is fetched (step S20). That is, CPU1
0 acquires panel data (hereinafter referred to as “new panel data”) from the operation panel 13 and stores it in the new panel data register of the RAM 12. Then, it is checked whether or not the play / stop switch 131 is turned on (step S21). This is because the bit corresponding to the play / stop switch 131 of the new panel data is "1".
And the bit corresponding to the play / stop switch 131 of the panel data (hereinafter, referred to as "old panel data") fetched in the previous panel processing and stored in the old panel data register is "0". It is done by checking if there is. The following mode switch 132, part selection switch 133 and music selection switch 1
The determination as to whether 34 has been turned on is performed in the same manner as above. Although not shown in the flowchart of FIG. 4, the new panel data is stored in the old panel data register at the end of this panel processing routine.

When it is determined in step S21 that the play / stop switch 131 is turned on, it is then checked whether or not play is in progress (step S).
22). This is done by checking whether the play flag is "1". The same applies below. If it is determined that the game is being played, the play flag is cleared to "0" and the mute processing is performed (step S23). At this time, a message indicating that the vehicle is stopped is displayed on the display unit 130. The muffling process is realized by sending predetermined data to the sound source 17. This realizes a function of stopping the automatic performance by pressing the play / stop switch 131 during the automatic performance.

On the other hand, if it is determined in step S22 that the play is not in progress, the play flag is set to "1" and the address initialization processing for each part is performed (step S24). At this time, a message indicating that the game is playing is displayed on the display unit 130. By the processing of step S24, as shown in FIG. 8, the start address of the automatic performance data of each part of the song designated by the song number selected at that time is set to an address register provided for each part. Is set to. As a result, the automatic performance data of each part is started to be read from each read address set in each address register in response to the pressing of the play / stop switch 131, and the automatic performance of each part is started from the beginning of the song. Has been realized. If it is determined in step S21 that the play / stop switch 131 is not turned on, the processes of steps S22 to S24 are skipped.

Then, it is checked whether or not the mode switch 132 is turned on (step S25). If it is determined that the mode switch 132 is turned on, it is then checked whether or not play is in progress (step S26). Then, if it is determined that the player is not playing, then it is checked whether or not the player is in the special mode (step S27). This is done by examining the mode flags. The same applies below. Then, if it is determined that the special mode is not in progress, the mode flag is set to "1" (step S28), and if not, the mode flag is cleared to "0" (step S29). At this time, a message indicating that the special mode has been entered or a message indicating that the normal mode has been entered is displayed on the display unit 130. With the above processing, the function of inverting the normal mode and the special mode each time the mode switch 132 is pressed is realized.

If it is determined in step S26 that the game is being played, steps S27 to S29 are skipped. In other words, the operation of the mode switch 132 during play is invalid. If it is determined in step S25 that the mode switch 132 is not turned on, the processes in steps S26 to S29 are skipped.

Then, it is checked whether or not the part selection switch 133 is turned on (step S30). Here, if it is determined that the part selection switch 133 is turned on, then it is checked whether or not play is in progress (step S31). When it is determined that the play is not in progress, the trigger part is changed (step S32). That is, the content of the part number register is incremented. At this time, the changed trigger part number is displayed on the display unit 130. On the other hand, if it is determined that the game is being played, this step S32 is skipped. In other words, the operation of the part selection switch 133 during play is invalid. If it is determined in step S30 that the part selection switch 133 is not turned on, steps S31 and S32 are performed.
Processing is skipped.

Then, it is checked whether or not the music selection switch 134 is turned on (step S33). here,
If it is determined that the music selection switch 134 has been turned on, then it is checked whether or not play is in progress (step S34). When it is determined that the song is not being played, the song is changed (step S35).
That is, the content of the song number register is incremented. At this time, the changed song number is displayed on the display unit 130. After that, the process returns from this panel processing routine and returns to the main routine. On the other hand, if it is determined that the game is being played, the process of step S35 is not performed, and the process returns from this panel processing routine and returns to the main routine. In other words, the song selection switch 1 during play
The operation of 34 is invalid. If it is determined in step S33 that the music selection switch 134 is not turned on, the processes of steps S34 and S35 are not performed,
The process returns from this panel processing routine and returns to the main routine.

(4) Automatic Performance Processing Next, the details of the automatic performance processing performed in step S12 of the main routine will be described with reference to the flowchart of FIG.

In the automatic performance process, first, it is checked whether or not the clock is "0" by referring to the contents of the clock counter (step S40). When it is determined that the clock is "0", no timer interrupt has occurred since the clock was decremented to "0" in step S41 of the automatic performance process, that is, a predetermined time ( It is recognized that the tone generation processing timing has not been reached since the time (corresponding to one step time) has not elapsed, and the routine returns from the automatic performance processing routine to the main routine without performing the following processing. That is,
This automatic performance processing routine is called from the main routine in a predetermined cycle, but if the timing of sound generation processing is not reached, the automatic performance processing of step S41 and thereafter is not performed.

On the other hand, when it is determined that the clock is not "0", it is recognized that the tone generation processing timing has come, and the clock is decremented (step S4).
1). Then, it is checked whether or not the game is being played (step S42), and when it is determined that the game is not being played,
The processing of step S43 and the subsequent steps is not performed and the routine returns from this automatic performance processing routine and returns to the main routine. As described above, the stop function of the automatic performance is realized by the configuration in which the automatic performance processing in and after step S43 is not performed when not playing.

When it is recognized that the game is being played in step S42, gate time processing is then performed (step S43). In this gate time processing, the gate time (set by the automatic performance data processing (step S53) described later) set in the sounding register provided in the RAM 12 for all sounds being sounded is set. This is the process of decrementing and muting the sound whose decrementing result is zero. As a result, the function of producing only the note length given by the gate time data in the automatic performance data is realized.

Then, it is checked whether or not the special mode is in progress (step S44). If it is determined that the special mode is not in effect, the process proceeds to step S49 and the subsequent tone generation processes. That is, if not in the special mode, a normal automatic performance is performed in which the automatic performance is advanced while sounding all parts. On the other hand, if it is determined in step S44 that the special mode is in progress, then it is checked whether or not the processing of the unit section has ended (step S45). Whether or not the processing of the unit section is completed can be judged by whether or not bar data appears in the automatic performance data when the unit section is defined as one bar, for example. Here, the bar data is specific data inserted for each bar in the automatic performance data in order to indicate a bar division. Also, for example, when the unit section is defined as a plurality of measures, it can be determined by counting the number of times the bar data appears in the automatic performance data.

When it is determined in step S45 that the unit section is not ended, it is recognized that the processing is in the middle of the unit section, and the sound generation processing of each part is started from step S49. In this case, parts other than the trigger part are sounded, the trigger part is sounded in the first processing of the unit section, and the sound is suppressed in the second processing (details will be described later). On the other hand, step S4
If it is determined in 5 that the unit section has ended, then it is checked whether or not the mute is in progress (step S
46).

Here, "mute" means that the unit section of the trigger part is being processed without sounding, in other words, the second section of the unit section is being processed. For example, when the melody part is selected as the trigger part, the sounding process of the second unit section not including the melody sound is performed, not the sounding process of the first unit section including the melody sound. Say. Whether or not the mute is being performed is stored by a mute flag provided in the RAM 12. Therefore, whether or not the mute is being performed is also checked by checking the mute flag.

When it is determined in step S46 that the mute is being performed, the mute flag is set to "0" and the start address of the automatic performance data in the next unit section of each part is set in each address register. (Step S47). After that, the process proceeds to the sounding process of each part in and after step S49. As a result, the automatic performance shifts to the processing of the next unit section. On the other hand, when it is determined that the mute is not being performed, the mute flag is set to "1" and the start address of the automatic performance data of the relevant unit section of each part is set in each address register (step S48). After that, the process proceeds to the sounding process of each part in and after step S49. As a result, the automatic performance shifts to the second processing of the unit section.

Sound generation processing of each part (steps S49 to S
55) is performed as follows. That is, first, step time increment processing is performed (step S
49). In this step increment process, the content of the step time counter is incremented. Here, the step time counter is a counter provided in the RAM 12, and is used, for example, to count the elapsed time from the beginning of the bar. This step time counter
If the game is being played, it is counted up every predetermined time (time corresponding to one step time) according to the tempo. Next, the processing part is initialized to "0" (step S491). Here, the processing part is a part for which sound generation processing is about to be performed, and “processing part = 0” corresponds to, for example, a rhythm part. In the following order, “processing part = 1” is the code part and “processing part =”
“2” is assigned as a bass part, and “processing part = 3” is assigned as a melody part.

Then, it is checked whether or not the special mode is in progress (step S50). If it is recognized that it is not in the special mode, it is necessary to sound all parts, so it is necessary to generate the automatic performance sound of the processing part regardless of whether it is the trigger part or mute. It branches to step S53. On the other hand, if it is determined that the special mode is in effect, then it is checked whether the processing part is the trigger part (step S51). This is done by checking whether the number of the trigger part stored in the part number register matches the number of the processing part.

If it is determined that the processing part is not the trigger part, the process proceeds to step S53 in order to sound the part. On the other hand, if it is determined that the processing part is the trigger part, then it is checked whether or not the mute is being performed (step S52). If it is determined that the mute is not being performed, that is, if the process is the first time for the unit section, the process proceeds to step S53 to sound the part. On the other hand, when it is determined that the mute is being performed, that is, when the process is the second process of the unit section, the automatic performance data process of step S53 is skipped in order to suppress the sound of the part. Then, the process proceeds to step S54. With the above processing, the function of producing sound in the first processing of the predetermined unit section of the trigger part and not producing sound in the second processing is realized.

When the method of reducing the volume is adopted as the mute method instead of the method of suppressing the sound generation, when it is determined in step S52 that the mute is being performed, the velocity data in the automatic performance data is changed. It may be configured such that the volume is converted to be low and the process proceeds to step S53. According to this configuration, even when the player listens to the model at the first time and actually performs at the second time, the automatic performance sound is generated with a small sound, so that there is an effect that the music practice becomes easy.

In the automatic performance data processing of step S53, the following processing is performed. That is, first, a set of automatic performance data is read from the position of the ROM 11 designated by the address register corresponding to the processing part. Then, the contents of the step time counter and the read 1
The step time data in the set of automatic performance data is compared, and if they match, it is determined that the sound generation timing has arrived, and sound generation processing is performed. In the tone generation process, the key number, velocity and gate time in the automatic performance data read from the ROM 11 are stored in the tone generation register, and the tone color parameters corresponding to the key number and velocity are read from the ROM 11 to generate the tone generator 1.
Sent to 7. As a result, a musical tone corresponding to the automatic performance data is generated.

Then, the processing part is incremented (step S54), and it is checked whether or not the processing part becomes "4" (step S55). Here, if it is determined that the processing part is not "4", it is determined that the processing for all the parts has not been completed, and the process returns to step S50 and the processing for the next part is performed. On the other hand, when it is determined that the processing part has reached "4", it is determined that the processing for all parts has been completed, and the process returns from the automatic performance processing routine to the main routine.

As described above, according to the first embodiment, in the automatic performance device for automatically performing the musical sounds by simultaneously generating the musical sounds of the plurality of parts, the one selected from the plurality of parts by the part selection switch 133 is selected. The one trigger part is adapted to advance the automatic performance while continuously producing and not producing sound for each unit section having a predetermined length. For example, the unit section is 1 for the whole song.
When the measure is defined and the melody part is selected as the trigger part, the automatic performance including the melody is performed the first time and the melody is performed the second time for each unit section (1 measure). Automatic performance not included is performed. While such processing is repeated, the automatic performance proceeds sequentially.

Therefore, the player can listen to the automatic performance including the melody at the first time and practice the melody at the second time by actually playing the melody using the automatic performance as a model. If another part such as a chord part, a bass part or a rhythm part is selected as the trigger part, the user can practice while listening to the model of each part in the same manner as above. In this way, since it is possible to practice while listening and comparing the original musical sound of the trigger part and the musical sound played by the player, there is an advantage that effective training can be performed.

(Embodiment 2) The automatic musical instrument of Embodiment 2 is such that a repeat section can be set and a process of continuously producing sound and non-sounding is repeated for the set repeat section. .

The hardware configuration of the automatic performance device in the second embodiment is the same as that of the first embodiment, and the block diagram of the automatic performance device of the first embodiment shown in FIG. Used as a block diagram of the device.
The RAM 12 is provided with a section pointer, a start address register, and an end address register as shown in FIG. 9 in order to store a repeat section set by the operation panel 13 described later. The section pointer designates a pair of start address register and end address register which define one repeat section. The start address register stores the start address of the repeat section, and the end address register stores the end address of the repeat section.

The structure of the operation panel 13 used in the second embodiment is shown in FIG. Switches 135 to 138 are added to the operation panel 13 (see FIG. 2A) used in the first embodiment. The same or corresponding parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 2B, the repeat switch 1
The numeral 35 is composed of, for example, a push button switch, and is used by the performer for instructing the setting or cancellation of the repeat mode. The setting state of the repeat switch 135 is RAM
It is stored by the repeat flag provided in 12. When the repeat switch 135 is pressed when the repeat mode is not set (repeat flag = 0), the repeat flag is "1".
On the other hand, when the repeat switch 135 is pressed in the repeat mode (repeat flag = 1), the repeat flag is cleared to "0". That is, each time the repeat switch 135 is pressed, the repeat mode and the non-repeat mode are alternately repeated.

The number of times switch 136 is used to set the number of repetitions of the repeat section. The number of times switch 136 is composed of, for example, a push button switch. Each time the frequency switch 136 is pressed, the contents of the repeat frequency register provided in the RAM 12 (repeat frequency)
Is incremented. The contents of the repeat count register are the contents of the initialization process of the main routine (step S1).
In 0), it is set to “2”, for example.

The A switch 137 is used to set the beginning of the repeat section, and the B switch 138 is used to set the end of the repeat section. The section setting means of the present invention includes the A switch 137 and the B switch 138.

The A switch 137 is composed of, for example, a push button switch. When the A switch 137 is pressed during the automatic performance, the address of the automatic performance data read from the ROM 11 at that time (RAM 12
The address stored in the address register provided in 1) is set in the start address register indicated by the section pointer.

The B switch 138 is composed of, for example, a push button switch. When the B switch 138 is pressed during the automatic performance, the address of the automatic performance data (RAM 12
The address stored in the address register provided in 1) is set in the end address register indicated by the section pointer.

In the case of the above configuration, the address fetched in the start address register or the end address register is the address of the automatic performance data read from the ROM 11 when the A switch 137 or the B switch 138 is pressed. A start address and an end address can be set in units of one note (note).

The ROM is stored when the A switch 137 or the B switch 138 is pressed as an address to be taken into the start address register or the end address register.
It is also possible to use the address of the automatic performance data at the beginning of the bar to which the automatic performance data read from 11 belongs. This is because when the A switch 137 or the B switch 138 is pressed, the automatic performance data is searched retrospectively, and when the bar data is found, the address of the next automatic performance data of the bar data is fetched. realizable. According to this configuration, even if the timing of pressing the A switch 137 or the B switch 138 is slightly delayed, the beginning and end of the bar can be accurately set as the repeat section. Since the actual setting of the repeat section is often set in units of measures, this configuration is very useful.

Although not shown in FIG. 2B, the operation panel 13 is provided with a clear switch which is used when the start address and the end address are set incorrectly. When the clear switch is pressed, the section pointer, the start address register and the end address register are all initialized, and the initial value "2" is set in the repeat count register.

Next, the operation of the second embodiment will be described in detail with reference to the flowcharts of FIGS. 6 and 7.
In the second embodiment, the main routine (FIG. 3A) and the timer interrupt processing routine (FIG. 3) used in the first embodiment.
Since (B)) is used as it is, its explanation is omitted.

First, the details of the panel processing performed in step S11 of the main routine will be described in detail with reference to the flowchart shown in FIG. In the panel processing, first, the same processing as the panel processing routine of the first embodiment is performed (step S60). That is, the panel processing routine shown in FIG. 4 is called as a subroutine.

Then, it is checked whether or not the repeat switch 135 is turned on (step S61). Then, if it is determined that the repeat switch 135 is turned on, then it is checked whether or not play is in progress (step S62). Then, if it is determined that the player is not playing, then it is checked whether or not the player is repeating (step S63). This is done by examining the repeat flag. The same applies below. If it is determined that the repeat is being performed, the repeat flag is cleared to "0" (step S64).
At this time, a message indicating that the repeat mode has been canceled is displayed on the display unit 130. On the other hand, if it is determined that the repeat is not in progress, the repeat flag is set to "1" (step S65). At this time, a message indicating that the repeat mode has been entered is displayed on the display device 130. With the above-described processing, the function of alternately repeating the repeat mode and the non-repeat mode each time the repeat switch 135 is pressed is realized.

If it is determined in step S62 that the game is being played, steps S63 to S65 are skipped. In other words, the operation of the repeat switch 135 during the automatic performance is invalid. If it is determined in step S61 that the repeat switch 135 is not turned on, the processes in steps S62 to S65 are skipped.

Next, it is checked whether or not the number of times switch 136 is turned on (step S66). here,
If it is determined that the number-of-times switch 136 has been turned on, then it is checked whether or not play is in progress (step S67). When it is determined that the game is not being played, the repeat count is incremented (step S68). That is, the content of the repeat count register is incremented. At this time, the updated number of repeats is displayed on the display device 130. On the other hand, if it is determined that the game is being played, this step S68 is skipped. In other words, the number of times switch 136 during play
The operation of is invalid. If it is determined in step S66 that the number of times switch 136 is not turned on, the processes of steps S67 and S68 are skipped.

Then, it is checked whether or not the A switch 137 is turned on (step S69). Where A
When it is determined that the switch 137 has been turned on, it is then checked whether or not play is in progress (step S70). When it is determined that the game is being played, it is then checked whether the game is being repeated (step S71). If it is determined that the repeat is not in progress, the start address of the repeat section is set in the start address register indicated by the section pointer and the contents of the end address register are cleared (step S72). At this time, the set start address is displayed on the display unit 130.

If it is determined in step S71 that the repeat is in progress, step S72 is skipped and the start address and end address are not changed. This avoids the inconvenience caused by changing the start address or the end address during the repeat. If it is determined in step S70 that the play is not in progress, steps S71 and S72 are skipped, and the start address is not set and the end address is not cleared. This is because the automatic performance data is not read out and the start address cannot be set unless the play is being performed. If it is determined in step S69 that the A switch 137 is not turned on, the processes in steps S70 to 72 are skipped.

Then, it is checked whether or not the B switch 138 is turned on (step S73). Where B
If it is determined that the switch 138 is turned on, then it is checked whether or not play is in progress (step S74). Then, when it is determined that the game is being played, it is then checked whether the game is being repeated (step S75). If it is determined that the repeat is not in progress, then it is checked whether or not the start address has been set (step S76). This can be done, for example, by setting a predetermined flag when step S72 is executed and checking this flag. This predetermined flag is used, for example, in the next step S7.
It should be cleared when 7 is executed.

If it is determined that the start address has been set, the end address of the repeat section is set in the end address register indicated by the section pointer, and the section pointer is incremented (step S77). At this time, the set end address and the contents of the updated section pointer are displayed on the display unit 130. After that, the process returns from this panel processing routine and returns to the main routine.

On the other hand, if it is determined in step S76 that the start address is not set, step S7
The processing of 7 is not performed, and the process returns from this panel processing routine to return to the main routine. As a result, the function of always setting the start address and the end address in pairs is ensured.

When it is determined in step S75 that the repeat is in progress, steps S76 and S77, that is, the end address and the section pointer are not changed, and the process returns from this panel processing routine to return to the main routine. This avoids the inconvenience caused by changing the end address or the section pointer during the repeat. If it is determined in step S74 that the game is not being played, steps S75 to S7 are executed.
The processing of step 7, that is, the setting of the end address and the increment of the section pointer are not performed, and the process returns from this panel processing routine and returns to the main routine. This is because the automatic performance data is not read out and the end address cannot be set unless it is during play. Also,
If it is determined in step S73 that the B switch 138 is not turned on, steps S74 to S7.
The processing of 7 is not performed, and the process returns from this panel processing routine to return to the main routine.

Next, the automatic performance process performed in step S12 of the main routine will be described in detail with reference to the flowchart shown in FIG.

In the automatic performance processing, it is first checked whether the clock is "0" (step S80),
When it is determined that the clock is "0", the following process is not performed and the process returns from the automatic performance process routine to the main routine. On the other hand, when it is determined that the clock is not "0", the clock is decremented (step S81). Then, it is checked whether or not it is in play (step S52), and if it is determined that it is not in play, the following processing is not performed and the automatic performance processing routine is returned to the main routine. On the other hand, when it is recognized that the game is being played, gate time processing is performed (step S83). Step S above
The processing of 80 to 83 is the automatic performance processing of the first embodiment (FIG. 5).
This is the same as the processing of steps S40 to S43.

Then, it is checked whether or not the special mode is in progress (step S84). If it is determined that the special mode is not being executed, the process proceeds to the sound generation process of each part (see FIG. 5) in and after step S49, and if not, it is checked whether or not the repeat number counter is "0" (step S85). ). The content of the repeat counter in step S85 is used to determine whether or not the repeat section is currently being processed. That is, if the content of the repeat number counter is "0", it means that the repeat section is not being processed, and if it is not "0", it means that the repeat section is being processed.

When it is determined in step S85 that the content of the repeat number counter is "0" (the repeat section is not being processed), the automatic performance data read address (the address set in the address register) is then read. ) Is checked to see if it is the start address (step S86). That is, the contents of the start address register indicated by the section pointer at that time are compared with the contents of the address register. When it is determined that the address is the start address, the repeat counter is set (step S87). That is, the repeat count set by the count switch 136 and stored in the repeat count register is set in the repeat count counter provided in the RAM 12. As a result, the content of the repeat number counter becomes a value other than "0", the number of times to repeat is set, and it also indicates that the repeat interval is being processed. After that, the process proceeds to step S49, and sound generation processing of each part is performed.

On the other hand, if it is determined in step S86 that the read address is not the start address, it is recognized that the read address is in a section other than the repeat section (hereinafter referred to as "non-repeat section"), and the flow advances to step S49. Sound generation processing of each part is performed.

If it is determined in step S85 that the content of the repeat number counter is not zero, it is recognized that the repeat interval is being processed, and then it is checked whether or not it is the end address (step S88). .
Then, if it is determined that the address is not the end address, it is recognized that the repeat section is in the middle, and the process proceeds to step S49 to perform the sound generation process of each part.

On the other hand, if it is determined that the address is the end address, then it is checked whether or not the mute is in progress (step S89). If it is determined that the mute is being performed, the mute flag is set to "0" (step S90). Next, the content of the repeat counter is decremented (step S91), and it is checked whether or not the result has become zero (step S92).
If it is determined that the number has reached zero, it is recognized that the last sound has been generated in the second processing of the repeat section, and the start address of the automatic performance data in the section following the part is the address. It is set in the register (step S93). Then, after that, the process proceeds to step S49, and the sounding process of each part is performed. As a result, the automatic performance shifts to the processing of the next section. After that, if a repeat section is set as the "next section", the repeat section is repeatedly sounded, and if it is a non-repeat section, 1
Only pronounced once.

On the other hand, when it is determined in step S92 that the content of the repeat number counter is not zero, the start address of the automatic performance data of the repeat section of each part is set in each address register (step S9).
5). As a result, the automatic performance shifts to the first processing of the repeat section again.

On the other hand, if it is determined in step S89 that the mute is not being performed, the mute flag is set to "1" (step S94), and the start address of the automatic performance data in the corresponding repeat section of each part is set in each address register. Is set (step S95). As a result, the automatic performance shifts to the second processing of the section.

As described above, according to the second embodiment, in the automatic performance device for automatically performing the musical sounds by simultaneously generating the musical sounds of the plurality of parts, one trigger part is selected from the plurality of parts by the part selection switch 133. And the A switch 137 and the B switch 138 are used to set the repeat section, and the number switch 136 is used to set the number of repetitions of the repeat section. When the play / stop switch 131 is operated in such a state, the automatic performance data of each part is sequentially read from the beginning and sounded. However, when the repeat section is reached, sound generation and non-sound generation are performed for the repeat section. The process of continuously performing and is repeated the number of times set by the number of times switch 136. The repeat section can be set not only at one location but at a plurality of locations.

For example, when one repeat section is set and a melody part is selected as the trigger part, the repeat section is automatically played with the melody at the first time and the melody at the second time. Automatic performance not included is performed. These two automatic performances are set as one set, and the number of times (set) set by the number of times switch 136 is repeated.

As described above, according to the second embodiment, since it is possible to practice repeatedly while listening to the model of the desired section, more effective practice is possible.

In the second embodiment, sound is generated and non-sound is generated in the repeat section of the trigger part. However, as shown in the first embodiment, the repeat section is divided into a plurality of unit sections. While repeating the pronunciation and non-pronouncing in each unit section to advance the automatic performance, when the end of the repeat section is reached, it returns to the beginning and repeats the same processing,
This may be configured to be repeated the number of times set by the number of times switch 136.

Further, in the second embodiment, the number of repetitions of the repeat section is set in advance by using the number of times switch 136. However, the number of repetitions is not set, and the number of repetitions is infinite. Operation panel 1
It may be configured to escape from the repeat section when a specific switch provided in No. 3 is pressed. According to such a configuration, there is an advantage that the player can repeat the practice of the predetermined section until he is satisfied.

[0105]

As described in detail above, according to the present invention,
It is possible to provide an automatic performance device with excellent operability that enables effective practice while comparing the original musical sound of a predetermined part with the musical sound played by the player.
