Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an automatic accompaniment device for an electronic musical instrument that can easily add performance effects such as intro, fill-in, ending, and other special accompaniment patterns. [Prior Art] With the spread of electronic musical instruments such as electronic keyboards, electronic wind instruments, and electronic stringed instruments, it has become possible to easily enjoy performances with a variety of musical tones, and it has become possible to play many musical tones with one electronic musical instrument. It is becoming easier to obtain these types of musical tones. Furthermore, many electronic musical instruments equipped with automatic accompaniment devices have been developed in order to obtain a wide variety of performance effects with simple operation. In this case, automatic accompaniment can be performed using rhythm instrument sounds, bass and chord accompaniment, etc., which enhance musical expressiveness. Here, in an automatic accompaniment device that performs automatic accompaniment by combining automatic accompaniment using rhythm instrument sounds and automatic accompaniment using bass chord accompaniment, the timing at which the rhythm sounds are generated is, for example, 16 steps (corresponding to a 16th note). Silk pattern (hereinafter referred to as rhythm pattern)
specified by. In other words, specify whether or not to generate a rhythm sound for each step, read out the 16-step rhythm pattern sequentially at a constant tempo, and determine and control whether or not to generate a rhythm sound for each step. By controlling the sound generation timing and playing the sound while repeatedly reading out the above 16 steps, a musically rhythmic accompaniment effect can be obtained. Note that a plurality of rhythm sounds may be prepared, and in this case, the above control is performed independently for the plurality of rhythm sounds. Also, the timing at which the chord sounds are sounded is also independent of the rhythm pattern, for example, 16 steps. ft (hereinafter referred to as a chord pattern), and control the sounding timing of chord tones '41. Furthermore, the timing at which the bass sound is produced is also independent of the rhythm pattern and chord pattern, for example, 16.
The sound generation timing of the bass sound may be controlled based on a pattern having one set of steps (hereinafter referred to as a base pattern). At this time, the chord progression of the chord tones produced by the above chord pattern is usually determined by the performer's control over a specific key area on the keyboard (
This is performed at any time using the accompaniment key (hereinafter referred to as the accompaniment key). Also,
Chord progression data indicating each chord progression is stored in memory in advance, and by automatically specifying the chord as the chord pattern progresses based on this data,
There are also automatic accompaniment devices that allow performers to enjoy automatic accompaniment more easily. The designation of the bass progression of the bass notes sounded in the bass pattern, that is, how to designate the bass pitch according to the progression of the song, depends on the root of the chord type specified in each of the chord progression data above. Specify as the pitch of the sound. In addition to the normal accompaniment patterns, special patterns such as an intro pattern, a fill-in pattern, and an ending pattern are prepared for the above rhythm patterns, chord patterns, bass patterns, and chord progressions. 7, and by switching the accompaniment pattern during automatic accompaniment, a more effective performance can be achieved. [Problem to be Solved by the Invention] However, in the above conventional example, switching to the intro, fill-in, or ending pattern is performed by the performer himself during automatic accompaniment using a dedicated switch such as the intro switch, fill-in switch, or ending switch. This is done by giving manual instructions. For this reason, especially for beginners, there is a problem in that it is not possible to add the desired performance effect and it is difficult to enjoy simple automatic accompaniment. An object of the present invention is to enable even beginners to easily specify a special pattern, thereby realizing automatic accompaniment as expected by the performer. [Means for Solving the Problems] The present invention provides automatic accompaniment that performs automatic accompaniment by generating rhythm tones, bass tones, or chord tones based on accompaniment patterns such as rhythm patterns, bass patterns, or chord patterns, and chord progression data. equipment is assumed. Here, the rhythm pattern is a pattern including, for example, a set of 16 steps (corresponding to 16th notes) for specifying the timing at which rhythm sounds are to be produced. Then, in the rhythm pattern, it is specified whether or not to generate a rhythm sound for each step, and this 16-step rhythm pattern is sequentially read out at a constant tempo, and it is determined and controlled whether or not to generate a sound for each step. While controlling the sound generation timing of the rhythm tones, automatic accompaniment using the rhythm tones is performed while repeatedly reading out the above 16 steps. Similarly, the chord pattern is a pattern that is independent of the rhythm pattern and has a set of 16 steps, for example, for specifying the timing at which the chord tone is to be sounded, and the timing at which the chord tone is sounded is controlled based on this pattern. Furthermore, the bass pattern is also a pattern that is independent of the rhythm pattern and chord pattern and is made up of a set of 16 steps, for example, to specify the timing at which the bass sound is produced, and based on this pattern, the timing at which the bass sound is produced is determined. control. In addition, the chord progression data is data that specifies chord types, and specifies the types of chord tones and bass tones that are produced by the chord pattern and bass pattern sequentially over time. In the automatic accompaniment device, the accompaniment pattern storage means includes:
This means stores a normal accompaniment pattern and at least one type of special accompaniment pattern for accompaniment patterns that instruct the pronunciation of rhythm tones, bass tones, or chord tones related to automatic accompaniment. The special accompaniment pattern in this case includes, for example, an intro pattern, fill-in pattern, or ending pattern. The pattern switching data storage means is a means for storing pattern switching data for instructing switching of accompaniment patterns between the normal accompaniment pattern and each of the special accompaniment patterns in accordance with the progress of automatic accompaniment. That is, the pattern switching data may be used, for example, to start automatic accompaniment with an Indian loba pattern, to change automatic accompaniment to a fill-in pattern during automatic accompaniment in a normal pattern, or to change automatic accompaniment to a fill-in pattern when automatic accompaniment is finished in a normal accompaniment pattern. Instructs to change to automatic accompaniment based on the ending pattern and then end the song. At the time of automatic accompaniment, the automatic accompaniment control means sequentially reads out pattern switching data from the pattern switching data storage means, reads out the normal accompaniment pattern or each special accompaniment pattern from the accompaniment pattern storage means in accordance with the instructions of the pattern switching data, and performs the following based on the pattern switching data. This is a means of performing automatic accompaniment. Here, the pattern instruction switch provided in addition to the configuration of the automatic accompaniment device is a switch that instructs switching of the accompaniment pattern between the normal accompaniment pattern and each special accompaniment pattern. Further, the manual automatic accompaniment control means is a means for reading out the normal accompaniment pattern or each special accompaniment pattern from the accompaniment pattern storage means in accordance with instructions from the pattern instruction switch, and performing automatic accompaniment based on the reading. The automatic/manual mode selection switch is a switch for selecting whether automatic accompaniment is performed by the automatic accompaniment control means or automatic accompaniment is performed by the manual automatic accompaniment control means based on the player's operation of the pattern instruction switch. It is. Furthermore, when such a configuration is added, the accompaniment pattern for intro accompaniment is included in the special accompaniment pattern, and when the automatic mode is selected in the automatic/manual mode selection means, the accompaniment pattern for intro accompaniment is included in the special accompaniment pattern. The automatic accompaniment pattern is configured to start automatic accompaniment based on the normal accompaniment pattern or each special accompaniment pattern read out according to the instruction of the pattern switching data when a pattern instruction switch for instructing the pattern switching data is pressed. [Function] The function of the present invention is as follows. During automatic accompaniment, the automatic accompaniment control means sequentially reads pattern switching data from the pattern switching data storage means, reads the normal accompaniment pattern or each special accompaniment pattern from the accompaniment pattern storage means according to instructions of the pattern switching data, and performs the following based on the pattern switching data. Perform automatic accompaniment. Therefore, accompaniment effects using special patterns such as intro patterns, fill-in patterns, or ending patterns can be automatically added during automatic accompaniment, and even beginners who do not know how to use these patterns can easily add accompaniment effects using special patterns. You can enjoy the effect. In this case, by providing a manual mode in which the player can manually add the special pattern, it is possible to allow a player with advanced playing ability to freely add the above effect. Furthermore, when the automatic accompaniment mode is selected here, in addition to the normal automatic accompaniment start switch, if automatic accompaniment can also be started by the intro pattern specified switch, it will be possible for beginners to press the switch incorrectly. can be reduced. In this case, since the accompaniment pattern translated into 31i is forcibly selected by the pattern switching data read from the pattern switching data storage means, the intro pattern designation switch is also used as a normal start switch. [Embodiment] (Disaster 4 Parking) Fig. 1 is a block diagram of an embodiment of the present invention. A central control unit (CPU, hereinafter the same) is a control unit that controls the overall operation, and has a flag counter register group (FOR1 and below) 1011 inside.

It is a means for amplifying musical sound waveforms output from the accompaniment sound generating section 110 and the rhythm sound generating section 111 and emitting the sound, and is, for example, an amplifier, a speaker, or the like. FIG. 2 shows the appearance of the keyboard section 104 shown in FIG. 1. As shown in the figure, it is composed of a plurality of keys 1041, and in this embodiment, it generates a scale for one five octave from C2 of the 0 octave (OC=O) to 07 of the 5 octave (OC=5). can. Of these, accompaniment from 02 to B3 [1
042 functions as a key for specifying a normal scale during normal performance, but functions as a key for specifying a chord in a normal mode during automatic accompaniment, which will be described later. Also, adjacent to the keyboard section 104, the switch section 1 of FIG.
05 are arranged as shown in FIG. The switch section 105 is a group of switches for making various settings during automatic accompaniment. Rhythm switch (hereinafter referred to as SW) 105
1 consists of six switches #1 to #6, and by pressing any one of them, the rhythm during automatic accompaniment can be specified. In this case, each rhythm of rock, waltz, march, samba, folk, fusion, etc. is assigned to each rhythm 5W1051 from #1 to #6, for example. The auto chord progression 5W1052 is a switch for specifying an auto chord progression mode, which will be described later, and when this is pressed, the LED above it lights up. Start SWI O54 and stop SWI 5W1055 are switches for starting and stopping automatic accompaniment. Intro 5W1053, fill-in 5W1056, and ending 5W1057 are switches for starting intro performance, fill-in performance, and ending performance, respectively. Tempo up 5W105B and tempo down 5W105
9 are switches for increasing and decreasing the tempo of automatic accompaniment, respectively. The tone color changeover switch 1060 is a switch for switching between melody and tone color (in the figure, three tones #1 to #3 can be selected). Auto operation mode 5W1061 is a switch for specifying auto operation mode, which will be described later.
When this is pressed, the LED above it lights up. (Made by Part I11) First, the general operation of the embodiment having the above configuration will be described. First, during normal performance without automatic accompaniment, key information KI shown in FIG. 4 is input from the t+1 board section 104 of FIG. 1. The key information Kl includes 0N10FF information OF indicating key press/release, a key code KC indicating one of the 12 scales, and an octave code OC indicating the octave. Then, any key 1041 on the keyboard section 104
(FIG. 3), the CPU 01 generates pitch information corresponding to the pressed key based on the key code KC and octave code OC, and supplies it to the melody sound generation section 109. do. 1: Due to this, melody sound generating section 1
09 generates a melody sound based on the pitch information, and causes the sound to be emitted via the sound system 112. Next, during automatic accompaniment, it is possible to specify two types: normal mode and auto chord progression mode. First, in the normal mode, the performer can select one of six types of rhythms such as rock, waltz, etc. After that, when automatic accompaniment is started, the first
The rhythm accompaniment sound generation unit 111 shown in the figure starts producing rhythm accompaniment sounds using a plurality of rhythm instrument sounds in a rhythm pattern consisting of 16 independent steps for each rhythm instrument sound, and is repeated. In this case, 16 steps correspond to, for example, one measure on the musical score, and therefore, for example, the same rhythm pattern is repeated for each measure. In this state, the player presses the keyboard section 104 in FIG. 1 or 2.
By pressing any accompaniment key 1042 between 02 and B3, the accompaniment sound generating section 110 in FIG.
With a bass pattern consisting of six steps, accompaniment tones based on a predetermined bass tone are started and repeated. At the same time, the accompaniment sound generating section 110 of FIG. Accompaniment tones based on a chord consisting of four tones are started and repeated. In this way, in the normal mode, if a rock rhythm is selected, for example, in addition to the rhythm accompaniment of the rock rhythm pattern using a plurality of rhythm instrument sounds, the chord tones specified by the performer with the accompaniment key 1042 in FIG. Based on this, automatic accompaniment can be created using a bass accompaniment with a mouth/neck bass pattern and bass tone, and a chord accompaniment with a rock chord pattern and chord tone. At this time, the performer presses the key 104 of the scale higher than 83 on the keyboard section 104 in FIG.
1, the player can freely play the melody along with the accompaniment. Next, in auto chord progression mode, when you select a rhythm and start automatic accompaniment, just like in normal mode, the rhythm accompaniment starts and repeats as in normal mode, and at the same time, the rhythm accompaniment starts and repeats. Bass accompaniment and chord accompaniment also start with the pattern and chord pattern. In this case, the bass pattern and chord pattern repeat a predetermined 16-step pattern corresponding to the selected rhythm, but the bass note and chord note specified at this time are the predetermined 16-step pattern corresponding to the selected rhythm. The chord progression is automatically specified over multiple measures. In this way, in the auto chord progression mode, for example, if you select a rock rhythm, in addition to the rhythm accompaniment of the rock rhythm pattern using multiple rhythm instrument sounds, you will also receive the rock bass pattern/bass progression accompaniment and the rock chord pattern.・Automatic accompaniment can be performed by chord accompaniment of chord progression. Then, the performer
By using any key 1041 on the keyboard section 104 shown in the figure, the user can freely play a melody or the like along with the accompaniment. Next, in both the normal mode and the autochord progression mode, the performance tempo and melody tone can be changed during performance, and performance effects such as intro, fill-in, and ending can be added. In this case, two modes can be selected: normal operation mode and auto operation mode. In normal operation mode, the performer can use the tempo up 5W105B or tempo down 5W105 shown in Figure 3.
9 allows the tempo to be changed arbitrarily, and the melody/tone when the performer performs the melody can be changed arbitrarily by the tone changeover switch 1060. Furthermore, each performance effect can be added using the intro 5W1053, fill-in 5W1056, and ending 5W1057 shown in FIG. In the auto-operation mode, the tempo and melody/timbre are automatically changed/designated independently of the above-mentioned switch operations. Furthermore, performance effects are automatically added at arbitrary timings. This is a particularly characteristic feature of the present invention. In addition to the above operations, in both the normal mode and the autochord progression mode, the performer can switch rhythms during performance using rhythm 5W1051 in FIG. 3. (Su-?)L, = %-NitoΔKyohu LL) Next,
The detailed operation in normal mode during automatic accompaniment will be explained. FIGS. 5 to 10 are flowcharts of operations when the CPU 101 executes a program (not particularly shown), particularly those related to the normal mode. First, the FCRroll shown in FIG. 1 is shown in FIG. 13, and those related to the operation in normal mode are listed below. Rhythm number register RR (Fig. 13(a)); 3rd

(2) Operation First, when the performer turns on the power to the main body (not shown), the main operation flowchart shown in FIG. 5 starts, and initial processing is first performed at 3501. Details of this process are shown in FIG. In other words, 36 in the same figure
Various flags are initialized at 01-36092. Note that the reason why the contents of the tempo data register TR are initialized to 16 is to set the tempo to an intermediate value since the register can take values from 0 to 31 as described later. After these processes, end the initial process (
S 6092-+S 610). After the initial processing in FIG. 5 8501, 5502~
The processing loop of 5506 is repeated. First, in 5502, tempo processing is performed. Details of this process are shown in FIG. That is, in step 5701, it is determined whether or not tempo up 5W105B in FIG.
If it is determined that W has been pressed, the tempo data register TRO value is incremented by 1 in 5704, the tempo is increased, and the tempo processing is ended (S704-3703). If the judgment in 5701 is No, in S 702 the tempo down 5W in Figure 3 is performed.
It is determined whether or not the SW 1059 has been pressed, and if it is determined that the SW has been pressed, the value of the tempo data register TR is incremented by 1 in 5705, the tempo is lowered, and the tempo processing is ended (S 705-3703). Note that the value of the register is controlled so that it does not become less than 0 or more than 31, although not specifically shown. If the determination in step 5702 is NO, the tempo processing ends without performing tempo control (S702→S
703). After the tempo processing at 8502 in FIG. 5, initial rhythm switching processing is performed at 5503. The details of this process are shown in FIG. That is, 5801 is Riz 11SW1051 in FIG.
Determine whether or not the has been switched, and if YES, 5
The process advances to 801-3802, sets the value corresponding to the rhythm number of rhythm 5W1051 in the rhythm number register RR, switches the rhythm, and ends the initial rhythm switching process (S803-3804). Here, Fig. 13 (
As shown in a), values 0 to 5 are set in 3-bit binary numbers corresponding to rhythm numbers #1 to #6 (see also FIG. 3). On the other hand, if the rhythm 5W 1051 has not been switched and the determination in 5801 is No, the initial rhythm switching process ends without doing anything (S 801-3804).
. After the initial rhythm switching process of 8503 in FIG. 5 above, 550
31, it is determined whether or not auto operation mode 5W1061 in FIG. 3 has been pressed. Auto operation mode 5W1061
specifies whether to change the melody, change the tempo, and add intro, fill-in, and ending effects (described later) by the performer using the corresponding switches in Figure 3, or whether to do it automatically independently. The former is called the normal operation mode and the latter is called the auto operation mode.Which mode is currently in is determined by the auto operation flag AOF explained in FIG. 13 (0) in FOR107,1 in FIG. Indicated by value. In the initial state, the auto-operation flag AOF is reset to 0 (36021 in FIG. 6) in the initial processing of FIG. 5 3501, and the mode is normal operation mode. And Fig. 5 35031
A detailed operation flowchart of the auto operation mode process is shown in FIG. 22, but if the auto operation SWI O61 in FIG. 3 is not pressed, the determination at 52201 in FIG. The process in FIG. 5 55031 is then terminated. 22nd
The process shown in the figure will be explained in detail after the autochord progression process. After the auto operation mode processing in 35031 in FIG. 5 above, the auto code progression 5W10 in FIG.
52 is pressed. Currently, in the normal mode, the SW is not pressed, so the determination is NO. Subsequently, in step 5505, it is determined whether or not the intro 5W 1053 in FIG. 3 has been pressed. The case where the button is pressed will be described later. If the determination at 5505 is NO, it is determined at 5506 whether or not the star SW 1054 in FIG. 3 has been pressed. If Start 5W1054 is not pressed, the above 550
The process repeats steps 2 to 5506 and waits until any one of autochord progression 5W1052, intro 5WIO53, or start 5W1054 in FIG. 3 is pressed. When the performer presses the star SW 1054 in FIG. 3 in the standby state shown in FIG. 5 5502 to 5506 of the rhythm, the rhythm sound only reproduction operation starts. First, after the determination of 5506 becomes YES, 55081
Whether the value of the auto operation flag AOF is 1 or not,
That is, it is determined whether the mode is auto operation mode or normal operation mode. Now, since the flag is initialized to 0 in the initial processing of 5501 (36021 in FIG. 6), the normal operation mode starts, and the determination in 35081 becomes NO, and the process moves to 8509. Note that the process when the determination here is YES and the process proceeds to the auto operation mode 35082 will be explained in detail after the auto chord progression process is explained. In step 5509, it is determined whether the content of the accompaniment solo BF is 1 or not, that is, whether automatic accompaniment or autorhythm is being performed. Now, the flag is set to O during the initial processing of 5501.
(3608 in FIG. 6), the autorhythm is initially in progress and the determination in step 5509 is NO. Subsequently, if the performer does not press the accompaniment key 1042 shown in FIG. 2, the determination at 5519 becomes NO, and the rhythm reproduction process at 5514 is performed. The details of this process are shown in FIG. First, in steps 5901, 5902, and 5903, it is determined whether the value of the pattern register PR is 1.2 or 3, that is, whether the pattern to be automatically accompanied is a fill-in pattern, an intro pattern, or an ending pattern. When the performer presses the start 5W1054, the register is initialized to 0 in the initial processing of 3501 (3605 in Figure 6), so the pattern starts with this pattern, and all judgments in 5901 to 5903 are No. The process then proceeds to step 3904. In 5904, it is determined whether the value of the pattern change standby flag PTF is 0 or not. The function of this flag will be described later, but since the flag is initially set to 0 in the initial processing of 5501 (S 607 in Figure 6),
The determination in step 5904 is NO, and the process proceeds to step 5905. At step 5905, the step indicated by the counter value of the RC (rhythm counter) 103 in FIG. 1 is read out of the 16-step main rhythm pattern corresponding to the rhythm number indicated by the rhythm number register RR. Now, CP
The pattern memory section 106 connected to Ul0I stores a rhythm pattern (the chord pattern and the bass pattern will be described later) having a structure as shown in FIG. As shown in the figure, the rhythm pattern consists of four patterns: a main pattern, a fill-in pattern, an intro pattern, and an ending pattern, and each of these patterns has 16 steps of 0 to 15 for each rhythm of #1 to #6. It consists of the following patterns. In FIG. 15(a), the first
The rhythm pattern of each 16 steps in Figure 4 is shown. As shown in the figure, during automatic accompaniment, it is possible to specify whether or not a rhythm sound is to be generated for each step using a binary number of 0 or 1 for each of the eight rhythm instrument sounds. Here, BD is the bass drum sound, SN is the snare drum sound, CH is the closed-by-butt sound, OH is the oven-by-butt sound, and T1 to T2 are the tom 1
~ Kumu 3 sounds, CY is cymbal sound. From these configurations, in 3905 in FIG. 9, CPU10 in FIG.
I is the fourteenth pattern stored in the pattern memory section 106.
Of the main rhythm patterns shown in the figure, the rhythm numbers (#l to #6) corresponding to the values indicated by the rhythm J and number register RR are
R in Figure 1 from the main rhythm pattern of
Read the step corresponding to the counter value of e2O3. Following the above operation, at 5906 in FIG. 9, an instruction is given to the rhythm sound generating section 111 in FIG. 1 to generate the rhythm sound for which "1" is specified in the read step. At this time, as shown in FIG. 15(a), in order to generate about 8 types of rhythm sounds in parallel, the above operation is also necessary for 8 tones, but this is because the rhythm sound generation section 111 of FIG. By time-division operation, each rhythm sound can be performed independently. As a result, the rhythm sound generation section 111 generates rhythm sounds for each rhythm sound at timings based on the rhythm pattern, and the sounds are emitted via the sound system 112. When the process of 8906 is completed, the process proceeds to 3907, and 1
The rhythm sound playback process for the steps ends. When the rhythm reproduction process for one step is completed at 3514 in FIG. 5, the routine waits for input of a timer clock from the timer clock generator 102 in FIG. 1 by repeating 5515. When the timer clock is input, R in FIG.
e2O3 is counted up. After processing 5517.351B (described later), each determination of 55081.5509.3519 is N. Then, the rhythm reproduction process of 5514 is performed again. In this case, in 8905 of FIG. 9, RCIO3 of FIG.
Since the value of is incremented by +1, the rhythm numbers (#1 to #6) corresponding to the value indicated by the rhythm number register RR among the main rhythm patterns of FIG. The step read from the main rhythm pattern (any one of them) is one step ahead of the previous processing. Then, according to the read steps, rhythm sound generation processing is performed at 8906 in FIG. 9. As mentioned above, 55081 → 5509 → 551 in Figure 5
9-3514--3515-55113-35081→
By repeating the loop processing of 5509, the rhythm number register R of the main rhythm pattern in FIG.
The 16-step main rhythm pattern of the rhythm number (any one of #1 to #6) corresponding to the value indicated by R is sequentially read out, and rhythm sounds are generated in accordance with the rhythm pattern. In this case, RCIO3 in FIG. 1 is a hexadecimal counter,
After counting up to step 15, the process returns to step O, so that each rhythm tone is repeatedly sounded for a predetermined 16 steps. These 16 steps correspond to, for example, one bar on the musical score. That is, during automatic accompaniment, each rhythm 1 of about 8 types and tones are repeatedly played in a fixed rhythm pattern for each bar. In the rhythm sound only playback operation, the rhythm sound production speed is the speed at which Re2O3 in FIG. 1 is counted up at 8516 in FIG. 5, that is, the timer clock is input from the timer clock generator 102 in FIG. It is determined by the speed. The input timing of this timer clock is determined by CPUl0I in FIG.
Depending on the value of 31, 31 steps are determined. The value of the tempo data register TR is initialized to an intermediate value of 16 in the initial processing at 3501 in FIG. 5 (360 in FIG. 6).
2), it can also be changed at 3502 in FIG. 5 before automatic accompaniment. In addition to this process, the performer also performs tempo up 5W105B or tempo down 5W10 in FIG. 3 during the rhythm sound playback.
By operating 59, the value of the tempo data register TR can be changed at 5517 in FIG. This process consists of 5
This is exactly the same as the tempo processing in step 502, and is shown in FIG. 7, which has already been described. Through the above processing, the performer can change the tempo of the rhythm sound being produced even during automatic accompaniment. In the above rhythm sound only playback operation, which rhythm pattern of the rhythm number #1 to #6 is selected in the main rhythm pattern shown in FIG. 14 depends on the value O to 5 indicated by the rhythm number register RR. Corresponding #1 to #
The rhythm number 6 is selected. The value of this rhythm number register RR is changed at 3503 in FIG. 5 before the automatic accompaniment starts, but even when the performer is playing the rhythm numbers #1 to #6 in FIG.
By selecting the desired one from WI O51,
You can change the rhythm pattern arbitrarily. This operation is the fifth
This process is realized as a part of the various switching processes 5518 in the figure, and the details of the process are shown in FIG. First, the determinations in S1001 to S1003 are all NO (this will be described later), and the process proceeds to step S1004. Here, if the rhythm 5W1051 in FIG.
3, the various switching processes 8518 in FIG. 5 are completed. On the other hand, if the same SW is switched, the determination in step 31004 becomes YES, and the process proceeds to steps S1005 and S1006. In S1005, the previous rhythm number register RR
Copy the value to the prism number register PRR. In the next step 31006, a value corresponding to the rhythm number of rhythm 5W1051 is set in the rhythm number register RR to switch the rhythm. Next, in 31007, it is determined whether the counter value of Re2O3 (indicating the step to be sounded next) in FIG. It will be judged. If the determination in S1007 is YES, that is, the timing is just right, the process proceeds to s1oos, where it is determined whether the value of the autochord progress flag ACH is 1 or not. The current mode is normal mode, and the contents of the ACR are still initially set to O in the initial processing at 8503 in Figure 5 (3603 in Figure 6), so this determination is No and 310
Proceed to step 12. In S1012, the pattern change standby flag PTFO value is set to O, and then in S10
The process advances to step 13 and the various switching processes shown in 5518 in FIG. 5 are completed. That is, the value of PTF becomes O at exactly the right timing of the 16-step main rhythm pattern. On the other hand, if the determination in S1007 is NOl, that is, the timing is in the middle of the 16-step main rhythm pattern,
After the process proceeds to step 1014 and the value of the pattern change standby flag PTF is set to 1, the value of the pattern change standby flag PTF is set to 1.
The various switching processes in step 8 are completed. That is, at a timing in the middle of the 16-step main rhythm pattern, the value of PTF becomes 1. After changing the value of the rhythm number register RR and setting the value of the pattern change standby flag PTF as described above, 35081.5509.5519 in FIG.
The determination is NO, and the rhythm reproduction process of 5514 is started again. Here, if the rhythm changes at just the right timing of the main rhythm pattern of 16 steps, the value of the pattern change standby flag PTF is 0, so after going through steps 5901 to 5903 in FIG. becomes YES. Therefore, in the next step 8905, the rhythm number corresponding to the new value indicated by the rhythm number register RR due to the rhythm switching among the main rhythm patterns of FIG. 14 stored in the pattern memory section 106 of FIG. The main rhythm pattern is sequentially read out from step 0, and from then on, rhythm sounds are produced using the changed rhythm pattern. On the other hand, if the rhythm changes in the middle of the 16-step main rhythm pattern, the value of the pattern change standby flag PTF is l, so 5901 to 5901 in FIG.
After passing through 5903, the judgment of 5904 becomes No and 590
Proceed to step 8. At step 5908, among the main rhythm patterns shown in FIG. 14 stored in the pattern memory section 106 shown in FIG.
Read the step corresponding to the counter value. here,
Since the value corresponding to the rhythm number before the rhythm is switched is stored in the prerhythm number register PRR, the process does not proceed to 5906 until the value of Re2O3 in FIG. 1 is determined to be 15 in the next step 8909. The rhythm sound is produced using the original rhythm pattern before the rhythm is switched. Then, the above-mentioned rhythm playback process of 5514 is repeated through the loop of 55081 to 5518 of FIG. 5, and when the Re2O3(7) value of FIG. 1 becomes 15 at 8909 of FIG. When the rhythm pattern reaches the final 15 steps, the judgment becomes YES, and after the next judgment at 8910 becomes NO (the ACR value is 0 because it is normal mode), the pattern change standby flag PTF is set at 5913. The value is returned to O, 59
Proceeding to step 06, the final step of the main rhythm pattern before the rhythm is switched is sounded. After this operation, 5 in Fig.
When the loop of 5081 to S 518 is repeated and the rhythm playback process of 5514 is entered again, the PTF has been set to 0, so the 9th
The determination at 5904 in the figure is YES, and at 5905 the first
Among the main rhythm patterns shown in FIG. 14 stored in the pattern memory section 106 shown in the figure, the main rhythm pattern whose rhythm number corresponds to the new value indicated by the rhythm number register RR due to the rhythm switching starts from step O. The rhythm sounds are read out sequentially, and from then on, rhythm sounds are produced using the changed rhythm pattern. In this way, when the rhythm is switched at a timing in the middle of the 16-step main rhythm pattern, the main rhythm pattern before the rhythm is switched to a good timing is sounded, and then the new main rhythm pattern is not switched. While the rhythm playback process of 5514 is being repeated by the loop of 35081 to 5518, the performer enters the 3rd rhythm.
The operation when pressing the fill-in 5W1056 shown in the figure will be explained. In this case, the rhythm sound is generated using the fill-in rhythm pattern from that timing until the 15th step, and then the main rhythm pattern is returned to. The switching preparation process for this purpose is performed in various switching processes 35] and 8 in FIG. That is, in FIG. 10, as the determination in S1001 becomes YES, 51
The process moves to step 015, where the value 1 is set in the pattern register PR, and in step S1013, the various switching processes shown in FIG. 55518 are completed. After the value of the pattern register PR is changed as described above, the determination in S 5081.5509.5519 in FIG. 5 becomes NO, and the rhythm reproduction process in 5514 is started again. Then, in FIG. 9, since the PR=1, the determination in 5901 becomes YES, and the process proceeds to 3914. 5914, the first pattern stored in the pattern memory section 106 in FIG.
The step corresponding to the counter value of Re2O3 in FIG. 1 is read from the fill-in rhythm pattern of the rhythm number corresponding to the value indicated by the rhythm number register RR in the fill-in rhythm pattern in FIG. Thereafter, until the next step 5915 determines that the value of Re2O3 is 15, the process proceeds to 5906 and rhythm sounds are generated in the fill-in rhythm pattern. As shown above, even if the rhythm is not switched in the middle of the 16-step main rhythm pattern, it is immediately changed to the fill-in rhythm pattern. Thereby, a fill-in effect can be added to the rhythm sound being generated at the timing when the performer presses the fill-in 5W1056 in FIG. 3. Based on the above operations, 35081 to 351B in FIG.
The rhythm playback process of 5514 is repeated through the loop, and when the value of RCI03 of FIG. 1 becomes 15 at 8915 of FIG. 9, that is, when the next rhythm pattern to be generated becomes the final 15 steps. The determination in 8915 is YES, and the process advances to 3916. At 5916, the contents of the pattern register PR are returned to 0, and preparations are made to return to the main rhythm pattern. continue,
Processes 5916 to 5919 are performed, and these processes are performed in an autochord progression mode, which will be described later. After these processes, the process advances to 5906 and the rhythm sound of the final step of the fill-in rhythm pattern is generated. After the above operation, when the loop from 35081 to 3518 in FIG.
Since PR is set to 0, the determinations in steps 5901 to 5903 in FIG. 9 become NO, and the process returns to the sound generation operation based on the main rhythm pattern. While the rhythm playback process of 5514 is being repeated by the loop of 55081 to 5518, the performer
The operation when pressing Ending 5W1057 in the figure will be explained. In this case, after the rhythm tones are generated up to a point with good separation using the main rhythm pattern, the rhythm tones are generated using the 16-step ending rhythm pattern, and the automatic accompaniment using the rhythm tones is ended. The switching preparation process for this purpose is performed in various switching processes 5518 in FIG. That is, in FIG. 10, since the determination in S 1002 is YES, S 1
The process moves to step 016, where the value 3 is set in the pattern register PR, and the process proceeds to step S1007. In S1007, the Re2O3 counter value in Figure 1 is 0.
In other words, it is determined whether or not it is the right timing to break up the main rhythm pattern of 16 steps. If the determination in S 1007 is YES, that is, the timing is just right, the determination in 31008 is NO, and S
After the process proceeds to step 10I2 and the value of the pattern change standby flag PTF is set to O, the fifth
The various switching processes shown in FIG. 3518 are completed. That is, as in the case of rhythm switching during the rhythm sound reproduction operation, the PTFO value becomes 0 at a good timing after the main rhythm pattern of 16 steps. On the other hand, if the determination in S1007 is No, that is, the timing is in the middle of the main rhythm pattern of 16 staves, 31
After proceeding to step 014 and the pattern change standby flag PTFO value is set to 0, from 31013 to 3518 in FIG.
The various switching processes are completed. That is, at a timing in the middle of the 16-step main rhythm pattern, the value of PTF becomes 1. This is also the same as the case of rhythm switching. As above, the pattern
