The display circuit 10 includes the L provided on the operation panel described above.
It is composed of ED or LCD.

Here, the phrase switches PHSW1 and PHSW2 provided on the panel switch 1 will be described. Each of the phrase switches PHSW1 and PHSW2 has a ROM 3
Of the 100 phrase data stored in the
Any one of them is assigned. This assignment is arbitrarily performed by the operator by operating a phrase assignment switch or the like in another switch OTHER. When the phrase switches PHSW1 and PHSW2 are operated, the phrase data assigned to them is read, and a phrase performance sound based on the phrase data is generated.

Next, FIG. 3 shows a data format of the phrase data stored in the ROM 3. Each of the phrase data PDATAn (n = 1 to 100) has 1
The phrase number n of ~ 100 is set. First,
As the header PHDR, a tone color for each phrase (for example, a piano or a saxophone for a melody phrase, a rock drum or a jazz drum for a drum phrase), phrase timing, and the like are stored. The phrase timing data indicates the phrase playback timing in the playback of the song. Even when the operation timing of the phrase switches PHSW1 and PHSW2 is different from the beat timing, the playback is started from the beginning of the beat in synchronization with the song. Information to do. For example, it is indicated by a quarter note, an eighth note, or the like. Note that data of one sound such as a cymbal sound is stored as phrase data. When reproducing this phrase data in synchronization with the operation timing of the phrase switches PHSW1 and PHSW2, the phrase timing data should not be set. You may. Below the header PHDR, timing data PTM representing the note event interval as data representing the timing of occurrence of the note event by the number of clocks (the minimum resolution of the timing data is called a clock and corresponds to the interrupt signal generation interval in the timer 6). And note event data PNT to be generated at the timing. The note event data PNT includes note on / off indicating sounding / muting, note number indicating pitch (percussion instrument type in the case of a drum), and velocity mainly corresponding to sounding intensity. Finally, end data PEND indicating the end of the phrase is stored. The phrase data PDATAn is for one bar. When the end data PEND is read while the phrase switches PHSW1 and PHSW2 are pressed, the first timing data PTM is read again, and the phrase performance is repeated. It is supposed to be.

FIG. 4 shows song data stored in the RAM 4. As shown in this figure, the song data includes a header HDR including an initial tone color and an initial tempo of the song, timing data TIME indicating an event interval, note on / off, and note, as in the case of the phrase data. It is composed of note event data NOTE consisting of a number and a velocity, phrase event data PEVT relating to the operation of the phrase switches PHSW1 and PHSW2, and end data END. The phrase event data PEVT is stored in the phrase switch P
The operation information of the HSW1 and HSW2, that is, the information indicating the pressed switch of the phrase switches PHSW1 and PHSW2, the phrase number of the phrase data PDATAn assigned to the phrase switches PHSW1 and PHSW2, and the ON of the phrase switches PHSW1 and PHSW1 OFF
(Hereinafter referred to as gate time). The end data END indicates the end of the song.

B. Operation Next, the operation of the automatic performance device according to this embodiment will be described. (1) Outline of Processing Contents First, an outline of processing contents will be described with reference to FIG. FIG. 5 is a diagram showing a song play track and a song rec track stored in the RAM 4 and phrase tracks PT1 to PT4 virtually realized in parallel on the time axis. The operation differs slightly between playback and recording.
Each will be described step by step. First, at the time of normal automatic performance, that is, when playing the song play track,
Start / stop switch START / STOP is O
From the time of N to the time when it is turned on again (or until the end data END is reached), the song play track is read by the CPU 5 and the above-mentioned note event data N is read.
OTE occurs, and automatic performance of the song is performed. During this time, at time T1, the phrase event data PEVT
Is read out, and if the operation information of the phrase switch PHSW1 is recorded as the phrase event data PEVT, the phrase event data P
Phrase data PD of phrase number indicated in EVT
ATAn is read as the data of the phrase track PT1, and is reproduced for the time indicated by the gate time of the phrase event data PEVT. That is, the phrase switch PHSW1 read from the song data
Operates as that of the phrase track PT1.

Next, at time T2, during playback of the song play track, the operator sets the phrase switch PHSW.
2 is operated. In this case, the phrase switch P
Phrase data PDAT assigned to HSW2
An is read from the ROM 3 as data of the phrase track PT4, and from this time T2, the phrase track PT4 is reproduced simultaneously with the reproduction of the phrase track PT1. That is, the operation of the phrase switch PHSW2 operates as that of the phrase track FT4. In this way, the two phrases are reproduced in an overlapping manner.

In the same manner as described above, the phrase switch PH from the song data is used as the phrase event data PEVT.
When the operation information of SW2 is recorded, the phrase data PDATAn of the phrase number indicated in the phrase event data PEVT is read from the ROM 3 as the data of the phrase track PT2, and the phrase switch PHSW1 is operated by the operator. , ROM3
The phrase data PDATAn assigned to the phrase switch PHSW1 from the phrase track PT3
Is read as the data. As described above, the phrase tracks PT1, PT2, PT3, and PT4 correspond to the phrase switch PHSW1 event in the song, the phrase switch PHSW2 event in the song, the operation of the phrase switch PHSW1 by the operator, and the operation of the phrase switch PHSW2 by the operator. , And each phrase track operates independently. For this reason,
Up to four phrases can be played simultaneously.

Then, a start / stop switch ST
When ART / STOP is operated or when the end data END is read from the song data,
Reading of the song data stops.

Next, the recording of song data (overdubbing) will be described. After pressing REC switch RC, start / stop switch START / STO
After pressing P to start reading the song data, the phrase event data PEVT is read from the song play track at time T3 in the same manner as described above, and the phrase switch PVT is added to the phrase event data PEVT.
It is assumed that the operation information of HSW2 is recorded. In this case, the phrase data PDATAn of the phrase number indicated in the phrase event data PEVT is stored in the ROM3.
Is read as data of the phrase track PT2. Then, from time T3, the phrase track PT2 is reproduced.

Here, it is assumed that the phrase switch PHSW2 is operated at time T4. In this case, the phrase data PDATAn assigned to the phrase switch PHSW2 is read from the ROM 3 as the data of the phrase track PT2. That is, during the song recording, the operation of the phrase switch PHSW2 by the operator operates as that of the phrase track PT2. This is because the event of the phrase switch PHSW2 recorded as described above operates as that of the phrase track PT2 at the time of reproduction, and therefore, it is necessary to match the states. As a result, the phrase data PDDATA assigned to the phrase switch PHSW2 is replaced with the phrase data PDATAn reproduced until time T4.
ATAn is played. Then, the operation information of the phrase switch PHSW2, the phrase number of the newly recorded phrase data PDATAn, and the gate time of the phrase switch PHSW2 are recorded on the song recording track.

On the other hand, at the time T4, the phrase switch PHSW1 is used instead of the phrase switch PHSW2.
Is operated, the phrase data PDATAn assigned to the switch is read from the ROM 3 as the data of the phrase track PT1. That is, the operation of the phrase switch PHSW1 during recording operates as that of the phrase track PT1. As a result, from time T4, the phrase tracks PT1 and PT2 are reproduced simultaneously, the two phrases are reproduced in an overlapping manner, and the phrase event data PEVT is added to the song recording track.
Is recorded.

When the phrase switch PHSW1 or PHSW2 is operated, the corresponding phrase data PDATAn is stored in the phrase track PT1.
Or, when read and reproduced as 2, the phrase event data PEV is read from the song play track.
When T is read, the phrase switch PHSW
The reproduction of the phrase by the operation of 1 or 2 is stopped, and the phrase data PDATAn specified by the phrase event data PEVT is preferentially reproduced.

Then, the start / stop switch ST
After ART / STOP is turned on and the playback of the song play track and the recording of the song recording track are completed,
Phrase data PD recorded on song recording track
By mixing the ATAn with the song play track, the song play track is updated and overdubbing is completed.

In practice, the phrase switch PHS
When W1 and W2 are operated, the phrase data PDATA
n is not reproduced, but reproduced when the phrase timing is reached.

(2) Details of Operation Here, each variable used for controlling this operation will be described. These variables are set in a predetermined storage area of the RAM 4. REC switch flag REC: “1” is set when recording is enabled,
Otherwise, "0" is set. Song play run flag SRRUN1: "1" is set when the data of the song play track is being reproduced. Song Rec Run Flag SRUN2: "1" is set when data is being recorded on the Song Rec track. Phrase run flags PHRUN1 to PHRUN4: "1" is set when the phrase data PDATAn is being read. Song play time register STIME1: This is a time register indicating an event interval used when a song play track is reproduced. When the count becomes down to "0", the next recorded event data is read. Song Rec Time Register STIME2: A register for counting the elapsed time from the previous event during recording. Phrase on flag PH
ON1 to 4: when the phrase event data PEVT is read, or when the phrase switches PHSW1 and PHSW2
Is operated, "1" is set. Phrase number registers PHNUM1 to PHNUM4: The phrase numbers of the phrase data PDATAn to be read are set. Gate time registers GATE1, GATE2: OFF after detection of ON event of phrase switches PHSW1, PHSW2
Register for storing the gate time (switch pressing time) until an event is detected. Phrase assign register PHASIN1,2: Phrase switch PHSW
A register for storing the phrase numbers assigned to 1 and 2. Phrase time registers PHTIME1 to PHTIME4: Time registers indicating an event interval in the phrase data PDATAn. When the count value is down-counted to "0", the next recorded event data is read.

Next, the operation of the electronic musical instrument according to the present embodiment will be described in detail with reference to flowcharts shown in FIGS. When a power supply (not shown) of the automatic performance device is turned on, the CPU 5 starts executing a main routine whose flow is shown in FIG. First, the process proceeds to Step SA1, where an initialization process is performed. By this initialization process, the registers and flags in the RAM 4 are initialized. Then, the process proceeds to Step SA2, where the CPU 5 performs a switching process described later. Next, the flow advances to step SA3 to perform other processing such as display processing. Then, returning to step SA2,
Thereafter, the CPU 5 repeatedly executes steps SA2 to SA3.

§1. Normal performance (Phrase switch PHS
First, a case where a normal real-time performance is performed will be described. In a normal real-time performance, a player operates a keyboard switch KEY, KEY,. Also,
By operating the phrase switch PHSW1 or PHSW2 to play a desired phrase,
The phrase data PDATAn assigned to each is
Reproduced by the corresponding phrase tracks PT3 and PT4. The operation will be described below.

FIGS. 7 and 8 are flowcharts illustrating the processing flow of the switch processing routine executed in step SA2. First, in step SB1, it is determined whether an ON event of the REC switch RC has been detected. In this case, the determination result is “NO”
, And the process proceeds to Step SB6. And step SB
6, the start / stop switch START /
Determine whether the STOP ON event is detected,
In this case, the answer is “NO”, and step SB shown in FIG.
Proceed to 18.

<Phrase Switch PHSW1, Process 2> Next, at step SB18, the phrase switch PSW
It is determined whether an ON event of HSW1 or PHSW2 has been detected. Phrase switch P by the player
If HSW1 or PHSW2 has not been operated, the result of this determination is "NO", and step SB30
Proceed to. In step SB30, it is determined whether or not an OFF event of the phrase switch PHSW1 or PHSW2 has been detected.
In this other switch processing, the keyboard switch K
When any one of the panel switches such as EY, KEY,... Is operated, a flag indicating that each of the switches is operated is set. When the phrase assign switch is operated, the phrase switch PHS
The phrase data PDATAn is assigned to W1 and PHSW2, and the phrase number of the assigned phrase data PDATAn is assigned to the phrase assignment register PHASIN.
1, set to PHASIN2. Thereafter, the switch process ends, and the process returns to the main routine.

Timer interrupt processing In parallel with the execution of the main routine, the CPU
5 executes a timer interrupt process when a timer interrupt is performed by the timer 6. 9 to 12 show the processing flow of this timer interrupt processing. First, in step SC1, the song play / run flag SRUN1
Is determined to be “1”. During a normal performance, the result of this determination is "NO", and step SC shown in FIG.
Proceeding to 14, it is determined whether or not the gate time registers GATE1, GATE2 are "0". Unless the phrase is read based on the phrase event PEVT read from the song, the result of this determination is "YES" and the flow proceeds to step SC18. Then, it is determined whether or not the song rec run flag SRUN2 is "1". In this case, since the song rec / run flag SRUN2 is “0”, the result of the determination in step SC18 is “NO”, and the flow proceeds to step SC23 shown in FIG.

<Phrase Data PDATAn Reproduction Processing> Next, in step SC23, the value of the counter i is set to "1". Then, the process proceeds to Step SC24,
It is determined whether or not the song play / run flag SRUN1 is “1”. In this case, since the song play / run flag SRUN1 is “0”, the result of the determination in step SC24 is “NO”, and the flow proceeds to step SC29 shown in FIG. In step SC29, it is determined whether or not the phrase run flag PHRUNi is “1”. In this case, the result of the determination in step SC29 is “NO”, and the flow proceeds to step SC30. Then, in step SC30, it is determined whether or not the value of the counter i is "4", and if the result of this determination is "NO", the flow proceeds to step SC31 to increment the value of the counter i. Then, the process returns to step SC24. Less than,
Steps SC29, SC30, and SC31 are repeatedly executed, and when the value of the counter i becomes “4”, step SC3
The determination result at 0 is “YES”, and the timer interrupt processing ends.

§2. Normal processing (phrase switch PHS
W1 and W2) Switch processing On the other hand, in the processing described above, the phrase switch PHS
When W1 or PHSW2 is operated, the determination result in step SB18 shown in FIG.
Proceed to step SB19. Then, in step SB19, the song play / run flag SRUN1 is set to "1".
Is determined, if the automatic performance is not being performed, the determination result is “NO” and the process proceeds to Step SB20. Here, when the phrase switch PHSW1 is operated, in step SB20, the phrase assign register PHASI is stored in the phrase number register PHNUM3.
Set the contents of N1. Also, phrase switch PHS
When W2 is operated, the phrase number register PH
The contents of the phrase assign register PHASIN2 are set in NUM4. Next, the process proceeds to a step SB21, wherein the phrase number register PHNUM3 (or PHNU3) is used.
M4) Header PH of phrase data PDATAn indicated by
DR data (see FIG. 3) is read from the ROM 3;
Various settings such as supplying tone color data to the tone generator circuit 7 are performed.

Then, the process proceeds to a step SB22, wherein the first timing data PT of the phrase data PDATAn is obtained.

The result of determination in step SB30 is "NO",
Proceeding to step SB35, after executing other switch processing, returns to the main routine.

Timer Interrupt Processing In this case, in the timer interrupt processing, first, the determination result in step SC1 is "NO", the flow proceeds to step SC14, the determination result in step SC14 is "YES", and the flow proceeds to step SC18. . In this case, since the songwreck run flag SRUN2 is not “1”, the determination result in step SC18 is “NO”.
And the process proceeds to step SC23 shown in FIG.

<Phrase Data PDATAn Reproduction Processing> Next, in step SC23, the value of the counter i is set to "1". Then, the result of the determination in step SC24 is "NO", and the flow proceeds to step SC29.
In step SC29, the phrase run flag PHR
It is determined whether or not UNi is “1”. If the determination result is “NO”, the process proceeds to Step SC30. Then, in a step SC30, it is determined whether or not the value of the counter i is “4”, and the determination result is “NO”.
In step SC31, the process proceeds to step SC31. After the value of the counter i is incremented, the process returns to step SC24. Hereinafter, similarly to the processing described above, steps SC24 and SC2 are executed.
9, SC30 and SC31 are repeatedly executed.

In this case, the phrase switch PHSW1
(Or PHSW2) is operated, and in step SB23 of the switch process, the phrase run flag PHRUN is
Since “1” is set to 3 (or PHRUN4), when the value of the counter i becomes “3” (or “4”), the determination result in step SC29 is “YE”.
S "and proceeds to step SC32. Then, in step SC32, the phrase time register PHTIME3 set in step SB22 is decremented. Next, in step SC33, it is determined whether or not the phrase time register PHTIME3 is "0". If the phrase time register PHTIME3 has not yet reached "0", the flow advances to step SC30.

Hereinafter, every time the timer interrupt processing is performed,
In step SC32, the phrase time register PH

Set M. Then, the process proceeds to step SC30, and when the value of the counter i is “3”, the process proceeds to step SC31, returns to step SC24 again, and when it is “4”, returns to the main routine. Hereinafter, step SC3
4 or the above process is repeated until the data read in SC37 becomes the end data PEND.
Event data is output to the tone generator circuit at a predetermined timing.

The read data is the end data P
If it is END, the result of the determination in step SC35 is "YES", and the flow advances to step SC40 to set the phrase number register PHNUM3 (or PHNUM).
The first timing data PTM of the phrase data PDATAn indicated in 4) is read and set in the phrase timing register PHTIME3 (or PHTIME4). Thus, in the subsequent interrupt processing, the same phrase data PDATAn is repeatedly played from the beginning.

As described above, by setting the value of the counter i from "1" to "4" and allocating the processing according to the value of each register, the phrase tracks PT1 to PT4 virtually provided as described above are provided. Realization of playback. In this case, when the value of the counter i is “3”, it indicates the reproduction of the phrase track PT3.

Phrase switch PHSW1, OFF
Processing On the other hand, when the phrase switch PHSW1 or 2 that has been turned on is turned off,
The result of determination in step SB30 is "YES", and the flow proceeds to step SB31. And song-rec
It is determined whether or not the run flag SRUN2 is “1”,
If the result of the determination is "NO", that is, if the recording of the song recording track is not being performed, the process proceeds to step SB32.
Proceed to. Then, “0” is set to the phrase run flag PHRUN3 (or PHRUN4). Thereby, the reproduction of the phrase by the operation of the phrase switch PHSW1 or PHSW2 ends.

§3. Song Data Playback Process (Only Song Data Playback) Switch Process Next, the case of performing an automatic performance will be described. Here, a case where only the song data shown in FIG. 4 is reproduced is shown. In this case, the start / stop switch START
By operating / STOP, the song data is reproduced and an automatic performance is performed. First, when the start / stop switch START / STOP is operated, the determination result in step SB6 is “YES”, and the process proceeds to step SB7. Then, in a step SB7, it is determined whether or not the song play / run flag SRUN1 is "0". In this case, the result of the determination in step SB7 is "YES", and the flow proceeds to step SB8. Next, in step SB8, the REC switch flag R
It is determined whether EC is “1”. Since the REC switch has not been operated, the result of the determination in step SB8 is "NO", and the flow proceeds to step SB9. Then, in step SB9, various settings such as reading out the data (tone color, tempo, etc.) of the header HDR of the song data shown in FIG.

Thereafter, the flow advances to step SB10 to read out the first timing data TIME of the song play track and set the timing data TIME in the song play time register STIME1. Next, step S
Proceeding to B11, the song play / run flag SRUN1 is set to "1". As a result, the song data can be reproduced.

Here, the phrase switch PHS
Since W1 or PHSW2 has not been operated, the determination result in step SB18 is "NO", the process proceeds to step SB30, the determination result in step SB30 is also "NO", and the process returns to the main routine via step SC35.

Timer Interrupt Process <Song Play Track Read Process> Next, the timer interrupt process during the above process will be described. In this case, in step SB11 of the above-described switch processing, the song play / run flag SRRUN
Since "1" is set to 1, the result of the determination in step SC1 is "YES", and the flow proceeds to step SC2. Then, in step SC2, step SB
Song play time register STIME set in 10
Decrement one. Next, in step SC3, the song play time register STIME1 is set to "0".
Is determined, and if this determination is "NO", the flow proceeds to step SC14. Thereafter, every time the timer interrupt process is performed, the song play time register STIME1 is counted down in step SC2. As a result, when the song play time register STIME1 becomes "0", it means that the event occurrence timing has been reached, and the judgment result in step SC3 is "YE
S "and proceeds to step SC4. Then, in step SC4, the event data of the song play track is read. This event data is event data recorded next to the timing data TIME read immediately before.

Thereafter, the flow advances to step SC5 to determine whether or not the read event data is phrase event data PEVT. If the read event data is note event data NOTE, step S
The decision result in C5 is "NO", and step SC
Then, in step SC6, it is determined whether or not the event data is the end data END. Since the result is “NO”, the process proceeds to Step SC7, and the note event data NOTE is output to the tone generator circuit 7.
Thereby, the tone generator 7 forms a tone signal based on the above data, and the digital / analog converter 8 converts the tone signal into an analog signal and emits the sound from the speaker 9.

When the processing in step SC7 is completed, the flow advances to step SC8 to read the next data of the song play track. Then, the process proceeds to Step SC9 to determine whether or not the read data is the timing data TIME. If the result of this determination is "NO", that is, if a plurality of events have occurred at the same timing, the process returns to step SC5. If the read data is the note event data NOTE, the sound generation process is performed as described above.

On the other hand, step SC4 or step S4
If the event data read in C8 is phrase event data PEVT, the result of the determination in step SC5 is "YES", and the flow proceeds to step SC11. If the phrase event data PEVT records that the phrase switch PHSW1 has been operated, the phrase-on flag PHON1 is set to "1" and the phrase number register PHNUM1 is set.
Is set to the phrase number assigned to the phrase switch PHSW1, and the gate time register GATE1 is set.
Is set to the gate time of the phrase switch PHSW1. If the phrase event data PEVT records that the phrase switch PHSW2 has been operated, "1" is set in the phrase on flag PHON2, the phrase number is set in the phrase number register PHNUM2, and the gate time register is set. The gate time of the phrase switch 2 is set in GATE2.

Next, the flow advances to step SC12, where various settings such as reading out the header PHDR data of the phrase data PDATAn indicated in the phrase number PHNUM1 (or PHNUM2) from the ROM 3 and setting them in the tone generator 7 are made. Then, proceed to Step SC8,
The next data is read, and it is determined in step SC9 whether the data is the timing data TIME,
If not timing data TIME, step SC5
And the above processing is repeated. If the read data is the timing data TIME, the result of the determination at step SC9 is "YES", the process proceeds to step SC10, and the song play time register STI
The timing data TIME is set in ME1.

Next, when the process of step SC10 is completed, the process proceeds to step SC14. When the phrase event data PEVT is read in the above-described processing, the gate time register GATE1 (or GATE2)
Has a predetermined gate time, the result of the determination in step SC14 is "NO". Next, the process proceeds to step SC15 where the gate time register G
ATE1 (or GATE2) is decremented, and in step SC16, the gate time register GAT
It is determined whether E1 (or GATE2) has become “0”. If the gate time register GATE1 (or GATE2) is not "0", that is, if the timing of terminating the reproduction of the phrase event data PEVT has not reached, the process proceeds to step SC18. Thereafter, each time the timer interrupt process is performed, the gate time register GATE1 (or GATE2) is set in step SC15.
Count down. Thereafter, the process proceeds to Step SC18 and Step SC23.

<Phrase Data PDATAn Reproduction Processing> Next, in step SC23, the value of the counter i is set to "1", and the flow advances to step SC24. If the song play track is being reproduced, the result of the determination in step SC24 is “YES”, and the flow proceeds to step SC25. Then, in step SC25, it is determined whether or not the phrase timing has been reached. The phrase timing is set when the header PHDR of the phrase data PDATAn is read in step SC21, and is a value unique to each phrase such as a quarter note or an eighth note. If the phrase timing has not been reached yet, the determination result is “NO” and the process proceeds to step SC29.
Proceed to C26.

Here, the phrase event data PEVT
Is read and the phrase-on flag PHON1 is "1", the result of the determination in step SC26 is "YES", and the flow proceeds to step SC27. Then, in step SC27, the first timing data PTM of the phrase data PDATAn indicated by the phrase number register PHNUM1 is read and set in the phrase time register PHTIME1. Next, the process proceeds to step SC28, in which the phrase run flag PHRUN1 is set to "1" and the phrase on flag PHON1 is set to "0". At this point, the phrase timing waiting time has elapsed.

Next, when the phrase run flag PHRUN1 becomes "1", the result of the determination in step SC29 becomes "YES", and the flow proceeds to step SC32. Hereinafter, the phrase data PDATA at the time of the above-described real-time performance
n playback processing, the phrase tracks PT1 to PT4
For the phrase data PDATAn. In this case, when the value of the counter i is "1", the reproduction of the phrase track PT1 is realized.

Thereafter, the above-described interrupt processing is executed. As a result, if the gate time register GATE1 becomes “0” in step SC15, it means that the timing to end the reproduction of the phrase data PDATAn has been reached, and the result of the determination in step SC16 is “Y
ES ”and the process proceeds to Step SC17. Then, in step SC17, the phrase run flag PHRUN is set.
Set “0” to 1. As a result, the result of the determination at step SC29 for the corresponding phrase track is “NO”, and the reproduction for the phrase track is stopped.

If the read data becomes end data END in step SC4 or SC8, the result of the determination in step SC6 is "YES", and the flow advances to step SC13. And song play
“0” is set to the run flag SRUN1. Thereby, the reproduction of the song play track is stopped.

§4. Song Data Reproduction Process (In the Case of Recording Phrase Data PDATAn) Next, in the above-described song data reproduction process, by operating the phrase switch PHSW1 or PHSW2, the operation result is stored in the song data shown in FIG. The case of recording as "" will be described. In this case, first, since the REC switch RC is operated, the process proceeds to steps SB1, SB2, and SB3, the result of the determination in step SB3 becomes "NO", and the REC switch flag RE in step SB5.
Set "1" to C. When the start / stop switch START / STOP is operated, the process proceeds to step SB6, step SB7, and step SB8. Then, the decision result in the step SB8 becomes "YES", the process proceeds to a step SB12, where the timbre, the tempo and the like are written in the header HDR of the song recording track. Then, the process proceeds to a step SB13, where "0" is set in the song play time register STIME2, "1" is set in the song rec run flag SRRUN2, and "0" is set in the REC switch flag REC.

Next, in step SB10, the first timing data TIME of the song play track is read out and set in the song play time register STIME1, and in step SB11, the song play run flag SRUN1 is set to "1". Through these processes, the song play track is put into the playback state,
The song recording track enters the recording state. When the song data is recorded first, there is no data in the song play track, so only the recording is performed.

<Phrase Switch PHSW1 and PHSW2 Processing> Here, when the phrase switch PHSW1 or PHSW2 is operated, the result of determination in step SB18 is “YE
S ", and proceeds to step SB19. Since the song play track is being reproduced, step SB19 is executed.
Results in "YES" at step SB.
Proceeding to 24, in step SB24, it is determined whether or not the song rec flag SRUN2 is "1".
If the result of this determination is "YES", the control proceeds to step SB2.
Then, when the phrase switch PHSW1 is operated, "1" is set in the phrase ON flag PHON1, and the contents of the phrase assign register PHASIN1 are set in the phrase number register PHNUM1. When the phrase switch PHSW2 is operated,
The phrase on flag PHON2 is set to "1", and the contents of the phrase assignment register PHASIN2 are set to the phrase number register PHNUM2.

Next, the process proceeds to a step SB26, wherein the phrase number register PHNUM1 (or PHNUM2) is set.
The data of the header PHDR of the phrase data PDATAn indicated by is read out and set in the tone generator circuit 7 and the like. Then, the process proceeds to a step SB27, wherein the gate time register G
ATE1 (or GATE2) is set to “0”.

Next, if the phrase switch PHSW1 or PHSW2 is being pressed, the result of the determination in step SB30 is "NO", the flow advances to step SB35 to perform the other switch processing described above, and returns to the main routine.

Timer Interrupt Process Next, the timer interrupt process in the above-described process will be described. In the timer interrupt processing, steps SC1, S
Proceed to C2, SC3, song time register STIME
Each time 1 becomes “0”, the process proceeds to the processes after step SC4. At steps SC5 to SC13, note data NOTE is generated at a predetermined timing, the next event data is sequentially read, and timing data TIME is set in the song time register STIME1. Thereafter, this processing is executed for each interruption.

If the event data is the phrase event data PEVT, at step SC11 the gate time register GATE1 or GAT
The gate time is set in E2, and steps SC14 to SC14 are executed.
In C16, the gate time register GATE1 or GATE2 is decremented. Thereafter, the process proceeds to steps SC18 and SC23, and the reproduction of the phrase data PDATAn after step SC23 is performed. Thereafter, this processing is executed for each interruption.

When the phrase switch PHSW1 or PHSW2 is operated as described above, the gate time register GATE1 is set at step SB27.
Is set to "0", the result of the determination in step SC14 is "YES", and the process proceeds to step SC18 even if the phrase data has been read out based on the phrase event until then. Therefore, while the phrase switches PHSW1 and PHSW2 are ON,
Even when the phrase to be reproduced has reached the timing to end, the phrase run flag PHRUN1 or PHRUN2 is not reset to “0” in step SC17, and the phrase switches PHSW1 and PHSW1 are not reset.
The playback of the phrase corresponding to No. 2 does not end.

In this case, since the song recording track is in the recording state, the result of the determination in step SC18 is "YES", and the flow advances to step SC19. And
The song rec time register STIME2 is incremented, and the flow advances to step SC20 to determine whether a switch event has been detected. That is, in step SB35, it is determined whether or not a flag has been set for any of the switches related to the performance. Write event data from the switch to the song recording track.

Here, for example, the phrase switch PHS
When W1 is operated, the contents of the phrase assignment register PHASIN1, that is, the phrase number assigned to the phrase switch PHSW1 are written as new phrase event data PEVT together with the information that the event of the phrase switch PHSW1 has occurred. When the OFF event of the phrase switch PHSW1 is detected, the time (gate time) from when the ON event of the phrase switch PHSW1 is detected to when the OFF event is detected is written.

When an event such as a key switch KEY, KEY... Is detected, ON / event of the switch, note number, velocity and the like are written.
In the case of a switch whose velocity cannot be detected, for example, a constant value is written. In addition, when an event of a switch that changes a tone, a tempo, or a volume is detected, the event information is written. Then, when the writing of the event information of each switch is completed, the flag corresponding to each is reset. Next, the process proceeds to step SC22, where "0" is set in the song recording time register STIME2. Hereinafter, the phrase data PDATAn is reproduced for the phrase tracks PT1 to PT4 in and after step SC23 in the same manner as the above-described processing.

OF OF PHASE SWITCH PHSW1, PHSW1
F processing Next, in the processing described above, the phrase switch PHS
When W1 or PHSW2 is turned off, the result of determination in step SB30 is “YE” in the switch processing.
S ", and proceeds to step SB31. If the song recording track is being recorded, the song recording flag SRU
Since N2 is “1”, the result of the determination in step SB31 is “YES”, and the flow advances to step SB33.
It is determined whether the gate time register GATE1 or GATE2 is "0". This is to determine whether or not the phrase is being reproduced when the phrase switch PHSW1 or PHSW2 is turned off. In other words, after turning on the phrase switch PHSW1 or PHSW2, the phrase event PEVT is read from the song play track, and the phrase based on the phrase event PEVT is read from the phrase switch PHSW1 or PHS.
This is to prevent the reproduction of this phrase from being terminated midway when the reproduction is performed in place of the phrase based on W2. If the phrase event data PEVT read from the song play track remains when the phrase switch PHSW1 or PHSW2 is turned off, the phrase run flag PHRUN1 or PHRUN
If RUN2 is forcibly set to "0", the playback of the phrase ends. Therefore, the gate time register G
If ATE1 or GATE2 is "0", the result of the determination in step SB33 is "YES", the flow proceeds to step SB34, and the phrase run flag PH
"0" is set to RUN1 or PHRUN2. Thereby, the reproduction of the phrase ends.

On the other hand, if the gate time register GATE1 or GATE2 is not "0", since the phrase data based on the phrase event data PEVT is being reproduced as described above, the phrase run flag PHRU
The process proceeds to Step SB35 without setting “0” to N1 or PHRUN2. In this case, in steps SC14 to SC16 in the interrupt processing, the phrase run flag PHRUN1 or PHRUN1 is set until the gate time register GATE1 or GATE2 becomes "0".
Since RUN2 does not become “0”, the phrase is reproduced in step SC23 and thereafter.

§5. Song Data Reproduction Process (When Only Phrase Sound Processing is Performed by Phrase Switches PHSW1 and PHSW2) Next, in the song data reproduction process, there is an operation of the phrase switch PHSW1 or PHSW2. A case in which only a phrase is pronounced will be described. In this case, the determination result in step SB1 and step SB6 is “NO”, and the process proceeds to step SB18. Then, the result of the determination at step SB18 becomes "YES",
Proceeding to step SB19, the result of this determination is "YES" since the song play track is being reproduced, and
Proceed to step SB24. Thereafter, in step SB24, it is determined whether or not the song recording flag SRUN2 is "1". If the REC switch RC is not operated, "NO" is determined, and the process proceeds to step SB28.

If the phrase switch PHSW1 is operated, "1" is set in the phrase on flag PHON3 in step SB28, and the contents of the phrase assign register PHASIN1 are set in the phrase number register PHNUM3. When the phrase switch PHSW2 is operated, the phrase on flag 4 is set to "1", and the phrase number register PHNUM4 is set to the phrase assignment register PHASI.
Set the contents of N2. Next, the process proceeds to a step SB29, wherein the phrase number register PHNUM3 (or PNUM3) is set.
The data of the header PHDR of the phrase data PDATAn indicated by HNUM4) is read and set in the tone generator circuit 7 or the like.

Next, the timer interrupt processing will be described. Here, a case will be described in which the phrase switch PHSW1 is operated when the phrase is reproduced based on the phrase event data PEVT read from the song play track, and the phrase is reproduced in a superimposed manner.

<Phrase Data PDATAn Reproduction Processing> First, in this case, in the phrase data PDATAn reproduction processing in step SC23 and thereafter, when the value of the counter i is "1", the phrase event read out from the song play track as described above. The phrase data PDATAn is reproduced based on the data PEVT.

In this case, since "1" is set in the phrase on flag PHON3 in step SB28, when the value of the counter i becomes "3", the result of the determination in step SC26 is "YES". Becomes
Then, the process proceeds to a step SC27, where the first timing data PTM of the phrase data PDATAn indicated by the phrase number register PHNUM3 is read and set in the phrase time register PHTIME3. Next, the process proceeds to step SC28, in which the phrase run flag PHRUN3 is set to "1", and the phrase on flag PHON3 is set to "0".

Here, the phrase run flag PHRUN3
Is "1", the result of the determination in step SC29 is "YES", and the flow proceeds to step SC32. In step SC32, the phrase time register PHTIME3 is decremented, and in step SC33, the phrase time register PHTIME3 is set to "0".
Is determined. Phrase time register PH
If TIME3 has not yet reached “0”, the process proceeds to step SC30. If TIME3 has reached “0”, the process proceeds to step SC30.
Proceeding to C34, the phrase number register PHNUM3
The event data of the phrase data PDATAn indicated by is read. Phrase data PDATAn to be read here
Is the phrase data PDATAn assigned to the phrase switch PHSW1. Hereinafter, as described above, a tone is generated from the speaker based on the read event data. At this time, while the phrase data PDATAn is being reproduced, the phrase data PDATAn is reproduced in an overlapping manner.

In this case, the phrase track P
Simultaneous reproduction of the phrase track PT3 is realized during reproduction of T1.

OF of phrase switches PHSW1 and PHSW2
F processing On the other hand, the phrase switch PHSW1 or 2 is OFF
If so, the process from step SB30 is performed in the switch process as described above. Thereby, the reproduction of the phrase ends.

§6. Stop Processing Next, stop processing performed by operating the start / stop switch START / STOP during reproduction of song data will be described. In this case, the result of the determination in step SB6 is "YES", the process proceeds to step SB7, and the song play / run flag SRU
It is determined whether N1 is "0". During the playback of the song play track, the result of this determination is "NO", and the routine proceeds to step SB14. Then, in step SB14, “0” is set to the song play / run flag SRRUN1, the phrase run flags PHRUN1 and PHRUN2. Next, the process proceeds to step SB15, where it is determined whether or not the song-record run flag SRUN2 is "1". If the song-record track is not being recorded, the result of this determination is "NO", and the process proceeds to subsequent processes. If a song recording track is being recorded, step S
The decision result in B15 is "YES", the process proceeds to Step SB16 in which the song-record run flag SRRUN2
Is set to “0”. Then, the process proceeds to a step SB17, wherein the data recorded on the song recording track is mixed with the song play track, and the timing data TIM
By newly adding E, the song play track is updated.

(3) Summary Next, the operation according to the operation of the automatic performance device according to the present embodiment will be described using the above-described phrase tracks PT1 to PT4.

<Normal Real-Time Performance> After the power is turned on, the performer switches the keyboard switches KEY, KEY,.
