In such a configuration, the operation of the automatic performance control section 9 will be described with reference to the flowcharts of FIGS. When power is turned on to the electronic musical instrument of FIG. 1, the automatic performance control unit 9 executes step S of the main routine of FIG.
The process proceeds to A1 to perform initial setting of each unit of the apparatus. This initial setting is to set an initial tone color in the sound source unit 4, to store 0 in the status register ST in which 0 is stored when the disk 11 is not inserted into the disk device 10, and to set A in the AB repeat by the operator. 0 is stored in the AB status register ABST in which 0 is stored when the point and the point B are not set.
And resetting the automatic performance status flag APST to 0 which is set to 1 when there is automatic performance data in the automatic performance data RAM 1. Then, the automatic performance control section 9 proceeds to step SA2.

In step SA2, the disk controller 10 is controlled to drive the disk
The disk processing for reading out the automatic performance data from 1 is performed. FIG. 5 shows a routine of this processing. In this routine, in step SB1, it is determined whether or not the disk 11 has been inserted into the disk device 10. If the result of this determination is "NO", that is, if the disk 11 has not been inserted into the disk device 10, the process proceeds to step SB10.

On the other hand, if the result of the determination in step SB1 is "YE
If "S", that is, if the disk 11 is inserted into the disk device 10, the process proceeds to step SB2. In step SB2, it is determined whether or not the disk 11 inserted in the disk device 10 is a disk for automatic performance. If the result of this determination is "YES", that is, if the disk 11 inserted in the disk device 10 is a disk for automatic performance, the operation proceeds to step SB3.

[0012] At step SB3, after storing the 1 to the song number register SONGNUM multiple automatic performance data file 11b ₁ of the disk 11, 11b _2, the song number that corresponds to ... are stored, the process proceeds to step SB4. In step SB4, the disk device controller 12 is controlled to drive the disk device 11, and the automatic performance data file 11b of the disk 11 corresponding to the song number 1 is set.

On the other hand, when the result of determination in step SB2 is "NO", i.e., when the disk 11 is inserted in the disk device 10 is not a disk for automatic performance also, the process proceeds to step SB 6. In step SB 6, it determines whether repeat file 11c ₁ that corresponds to the automatic performance data file 11b ₁ on the disk 11 is created. If the result is "YES", i.e., if the repeat file 11c ₁ that corresponds to the automatic performance data file 11b ₁ to the disk 11 has already been created, the process proceeds to step SB 7.

[0014] At step SB 7, drives the disk device 10 controls the disk device control unit 12, the disk 1
After storing the repeat data RAM9a from 1 repeat file 11c ₁ reads the repeat data (see FIG. 3), the flow proceeds to step SB 8. In step SB 8,

[0015] On the other hand, the judgment result of step SB 6 is "N
For O ", i.e., if the repeat file 11c ₁ that corresponds to the automatic performance data file 11b ₁ on the disc 11 has not been created yet also, the process proceeds to step SB 9. At step SB 9 , the status register ST indicates that the disk 11 is inserted into the disk device 10.
After storing and proceeds to step SB 10.

In step SB10, it is determined whether or not the disk 11 has been removed from the disk device 10. If the result of this determination is "YES", that is, if the disk 11 has been removed from the disk device 10, the process proceeds to step SB11.

In step SB11, after resetting the status register ST to 0, the process returns to the main routine of FIG. 4 and proceeds to step SA3. On the other hand, step SB10
Is "NO", that is, even when the disk 11 is not removed from the disk device 10, FIG.
Then, the process returns to the main routine and proceeds to step SA3.

At step SA3 in FIG. 4, a song select process that is performed when the song select switch 7d of the various operators 7 in FIG. 2 is operated is performed. FIG. 6 shows a routine of this processing. In this routine, in step SC1, the operator determines whether to change the song number with the song select switch 7d made of up switch 7d ₁ and down switch 7d ₂ of FIG. That is, it is determined whether or not the operator has selected another automatic performance data stored on the disk 11 instead of the automatic performance data 1 currently stored in the automatic performance data RAM 1. If the result is "YES", i.e., the operator up switch 7d ₁ and down switch 7d ₂
If the song number has been changed using the song select switch 7d, the process proceeds to step SC2.

In step SC2, it is determined whether or not 1 indicating that the disk 11 is inserted into the disk device 10 is stored in the status register ST. If this determination result is “YES”, that is, if 1 is stored in the status register ST, step SC
Proceed to 3. In step SC3, the song number changed by the operator is stored in the register SONGNUM, and the process proceeds to step SC4.

In step SC4, the song number stored in the register SONGNUM is displayed on the display 8, and then the operation proceeds to step SC5. In step SC5,
Drives the disk device 10 controls the disk device control unit 12, automatic performance data file 11b _1, 11b ₂ of the disc 11 corresponding to the song number stored in register SONGNUM, reads the automatic performance data from ... After storing the data in the automatic performance data RAM 1, step S
Proceed to C6.

In step SC6, it is determined whether or not a repeat file 11c corresponding to the automatic performance data stored in the automatic performance data RAM 1 has been created on the disk 11. If the result of this determination is "YES", that is, if the repeat file 11c corresponding to the automatic performance data stored in the automatic performance data RAM 1 has already been created on the disk 11, the process proceeds to step SC7.

In step SC7, the disk device controller 12 is controlled to drive the disk device 10, and the disk 1
1 from the repeat file 11c (FIG. 3
Read out) and stored in the repeat data RAM 9a, and then proceed to Step SC8. In step SC8, A
After 2 indicating that the setting of the points A and B of the AB repeat has been completed by the operator is stored in the B status register ABST, the process returns to the main routine of FIG.
Proceed to.

At step SA4 in FIG. 4, an automatic performance process is performed. The routine of this processing is shown in FIGS. In this routine, in step SD1, it is determined whether or not the automatic performance start / stop switch 7c of FIG. 2 has been turned on. If the result of this determination is "YES",
If the automatic performance start / stop switch 7c is turned on, the process proceeds to step SD2.

At step SD2, it is determined whether or not the automatic performance status flag APST is set to "1". If the result of this determination is "YES", that is, the flag A
If PST is set to 1, step SD
Proceed to 3. In step SD3, the status register S
It is determined whether or not 2 indicating that automatic performance is being performed is stored in T. If the result of this determination is "NO", that is, if 2 is not stored in the status register ST, the operation proceeds to step SD4.

In step SD4, the automatic performance is started, that is, the start address S is sent to the address sending section 13.
After outputting the TADS and outputting the start signal SST to the read control unit 6, the process proceeds to step SD5. As a result, the address sending unit 13 outputs the start address STADS to the read control unit 6, so that the read control unit 6 is triggered by the start signal SST and starts reading the automatic performance data APD from the automatic performance data RAM1. Accordingly, the automatic performance data APD is sequentially read from the automatic performance data RAM1, and the event decoder 3 inputs the automatic performance data APD and decodes the key data KD, the registration data RD, and the tempo data TD.

As a result, the sound source unit 4 outputs the key data KD
Then, the tone data is generated by inputting the registration data RD.
The tempo clock generator 5 receives the key data KD and the resist data RD and generates a tempo clock.
The automatic performance data APD is sequentially read from the automatic performance data RAM1.

In step SD5, 2 indicating that the automatic performance is being performed is stored in the status register ST, and then the flow advances to step SD10 in FIG. On the other hand, if the decision result in the step SD3 is "YES", that is, if 2 is stored in the status register ST, the step SD6
Proceed to.

In step SD6, the automatic performance is stopped, that is, after the stop signal SSP is output to the read control unit 6, the process proceeds to step SD7. Thereby, the read control unit 6 is triggered by the stop signal SSP, and stops reading the automatic performance data APD from the automatic performance data RAM1. Therefore, the sound source unit 4 stops generating the musical sound.

In step SD7, "1" indicating that the disk 11 is inserted into the disk device 10 is stored in the status register ST, and then the flow advances to step SD8.
In step SD8, the AB status register ABST
It is determined whether or not 1 indicating that the point A and the point B of the AB repeat are being set by the operator. If the result of this determination is "YES",
That is, when 1 is stored in the register ABST, the process proceeds to step SD9.

In step SD9, "0" is stored in the AB status register ABST, that is, the operator turns on the automatic performance start / stop switch 7a in FIG. 2 during the setting of points A and B of the AB repeat described later. in case of,
The setting of the points A and B of the AB repeat up to that point is canceled. Then, the automatic performance control section 9 proceeds to step SD10 in FIG. On the other hand, when the determination result in step SD8 is "NO", that is, when 0 is stored instead of 1 in the register ABST, step SD8 in FIG.
Proceed to 10.

At step SD10 in FIG. 8, AB AB in FIG.
It is determined whether the setting switch 7a has been turned on. This determination is made here because the AB repeat setting is limited only during automatic performance. Step SD10
Is "YES", that is, if the AB setting switch 7a is turned on, the process proceeds to step SD11. In step SD11, it is determined whether or not 2 indicating that the automatic performance is being performed is stored in the status register ST. If the result of this determination is "YES",
If 2 is stored in the status register ST, the process proceeds to step SD12.

At step SD12, it is determined whether or not 1 indicating that the operator is in the process of setting points A and B of AB repeat is stored in the AB status register ABST. This step SD1
At the time of the process 2, the register ABST contains 0
Or 1 is stored. In other words, when 0 is stored, the points A and B have not been set yet, so that A
When the point is set and 1 is stored, the point A and the point B are being set, and the point B is set in the processing of steps SD16 to SD21 described later. is there. If the result of the determination in step SD12 is "N
O ", that is, the register ABST is set to 0 instead of 1.
Is stored, the flow advances to step SD13.

In step SD13, the current address is written to the repeat data RAM 9a as the point A address. That is, the address sending unit 13 is controlled and the read control unit 6 is controlled.
, The current address PADS is read out and written into the repeat data RAM 9a. Then, the automatic performance control section 9 proceeds to step SD14.

In step SD14, the resist data up to the point A is written in the repeat data RAM 9a. In the normal mode of the automatic performance, the automatic performance data RAM 1
Are automatically read out from the beginning of the music and sounded. As described above, the automatic performance data includes, in addition to the key data KD, registration data RD such as timbres, program changes and effects. Is changing. Therefore, step SD1
When the point A is set in the process 3, it is necessary to know what kind of registration data RD should be used to perform the automatic performance at the point A.

Then, the automatic performance control section 9 controls the registration data detection section 14 to search the automatic performance data stored in the automatic performance data RAM 1 from the beginning of the music, and to find out what kind of registration data It is detected whether the RD is stored. Then, after the registration data RD is written in the repeat data RAM 9a, the process proceeds to step SD15. In step SD15, 1 is stored in the AB status register ABST, indicating that the operator is in the process of setting the points A and B of the AB repeat, and then step SD in FIG.
Proceed to 22.

On the other hand, if the result of determination in step SD12 is "Y
If "ES", that is, if 1 is stored in the register ABST, the process proceeds to step SD16. Step S
At D16, the current address is written into the repeat data RAM 9a as the point B address. That is, the address sending unit 13 is controlled to read the current address PA from the reading control unit 6.
DS is read out and written into the repeat data RAM 9a. Then, the automatic performance control unit 9 proceeds to step SD17.
Proceed to.

At step SD17, the automatic performance data R
It is determined whether or not the repeat file 11c corresponding to the automatic performance data stored in AM1 exists on the disk 11. If the result of this determination is "NO", that is, if the repeat file 11c corresponding to the automatic performance data stored in the automatic performance data RAM 1 does not exist on the disk 11, the process proceeds to step SD18.

At step SD18, the automatic performance data R
After a repeat file 11c corresponding to the automatic performance data stored in AM1 is created in a predetermined area in the disk 11, the process proceeds to step SD19. On the other hand, step SD17
Is "YES", that is, when the repeat file 11c corresponding to the automatic performance data stored in the automatic performance data RAM 1 exists on the disk 11,
Proceed to step SD19.

In step SD19, the disk device control section 12 is controlled to drive the disk device 10, and the repeat data consisting of the A point address, the B point address, and the resist data up to the A point written in the repeat data RAM 9a is stored. After writing to the repeat file 11c of the disk 11, the process proceeds to step SD20. In step SD20,
Perform AB repeat reproduction. That is, the repeat data RA
The resist data RD from M9a to the point A address, point B address and point A is read out,
After outputting the address of point A as the start address STADS, outputting the resist data RD to the event decoder 3 and outputting the start signal SST to the read control unit 6, the process proceeds to step SD21.

As a result, the address sending unit 13 outputs the start address STADS to the read control unit 6, so that
The read control unit 6 is triggered by the start signal SST and starts reading the automatic performance data APD from the area of the point A address of the automatic performance data RAM1. Therefore, the automatic performance data APD is sequentially read out from the area of the address A of the automatic performance data RAM 1 and the event decoder 3 inputs the automatic performance data APD and inputs the key data K.
D and the tempo data TD are decoded, and these data and the resist data R supplied from the automatic performance controller 9 are decoded.
D is output.

As a result, the tone generator 4 transmits the key data KD
Then, the tone data is generated by inputting the registration data RD.
Since the tempo clock generator 5 receives the tempo data TD and generates a tempo clock, the read controller 6
Is the automatic performance data RAM 1 according to the tempo clock.
, The automatic performance data APD is sequentially read out. At this time, the automatic performance control section 9 controls the address sending section 13 to always read the current address PADS from the read control section 6, and constantly compares the read current address PADS with the point B address. Then, it is determined whether or not the repeat reproduction has been performed up to the point B address. When the repeat playback Ru performed until point B address, the address sending section 13
The address A is output as the start address STADS, and the resist data RD is output to the event decoder 3. As a result, the AB repeat reproduction operation from the point A address is performed again.

In step SD21, points AB and B of the AB repeat by the operator are stored in the AB status register ABST.
After storing 2 indicating that the point setting is completed, the process proceeds to step SD22 in FIG. On the other hand, if the decision result in the step SD10 is "NO", that is, the AB setting switch 7a
Is not turned on, the step SD22 in FIG.
Proceed to. In addition, the determination result of step SD11 is “NO”
In the case of, that is, when 2 is not stored in the status register ST, that is, when the automatic performance is not being performed, the process proceeds to step SD22.

In step SD22, it is determined whether or not the AB repeat switch 7b in FIG. 2 has been turned on. If this determination is "YES", that is, if the AB repeat switch 7b is turned on, the process proceeds to step SD23. In step SD23, the AB status register A
It is determined whether or not 2 indicating that the setting of the points A and B of the AB repeat by the operator is completed is stored in the BST. If this determination result is “YES”, that is, if 2 is stored in the register ABST, step S
Proceed to D24.

In step SD24, AB repeat reproduction is started. This processing is the same as the processing in step SD20 described above, and a description thereof will be omitted. Then, the automatic performance control section 9 proceeds to step SD25. On the other hand, if the determination result in step SD22 is "NO", that is, if the AB repeat switch 7b is not turned on, the process proceeds to step SD25. When the result of the determination in step SD23 is "NO", that is, when 2 is not stored in the register ABST, the process proceeds to step SD25. In step SD25, after performing other automatic performance processing, the process returns to the main routine of FIG.
Proceed to step SA5.

In step SA5 in FIG. 4, after performing a keyboard process that operates when any key of the keyboard of the keyboard section 2 is pressed or released, the process proceeds to step SA6. Since this keyboard processing is known, detailed description thereof will be omitted. In step SA6, after performing other processes other than the above-described processes, the process returns to step SA2.

As described above, according to the above-described embodiment, since the repeat data relating to the AB repeat reproduction is stored in the repeat data RAM 9a or the disk 11, the operator can operate the AB repeat switch 7b in FIG. Even if the mode is canceled, the phrase set previously can be heard again only by turning on the AB repeat switch 7b until the point A and the point B of the AB repeat are newly set.

Since the repeat data is stored in the disk 11, the automatic performance data in which the AB repeat points A and B are already set are read from the disk 11, and the AB repeat switch 7b is turned on. Just listen to the phrase you set earlier. In the above-described embodiment, an example is shown in which the disk 11 such as a floppy disk is used as the external storage device, but the present invention is not limited to this. For example, a memory card or another storage medium may be used.
