The operation of the electronic musical instrument will be described below with reference to flowcharts shown in FIGS. When the power switch 301 of the automatic performance device is turned on, C
The PU 4 executes a main routine whose flow is shown in FIG. First, the process proceeds to step S1, where initial values are set in control registers and flags in the RAM 6. Next, proceeding to step S2, if an ON event of any of the pad switches in the pad switch group 1 has been detected at that time, a pad switch processing routine shown in FIG. 9 is executed. Next, the process proceeds to step S3, and if an ON event of any key of the ten keys 201 is detected at that time, a ten key ON event processing routine shown in FIG. 10 is executed. Next, proceeding to step S4, if an ON event or an OFF event of the record switch 206 is detected at that time, a record switch ON / OFF event processing routine shown in FIG. 11 is executed. Next, proceeding to step S5, if an ON event of any of the song switches 202 to 204 is detected at that time, a song switch ON event processing routine shown in FIG. 12 is executed. Next, proceeding to step S6, if the on event of the intro / ending switch 209 is detected at that time, the intro / ending switch on event processing routine shown in FIG. 13 is executed. Next, the process proceeds to step S7, and if an ON event of the start / stop switch 210 is detected at that time, a start / stop switch ON event processing routine whose flow is shown in FIG. 14 is executed.

Next, the process proceeds to step S10. If an on event of the auto base switch (not shown) is detected at that time, an auto base switch on event processing routine shown in FIG. 17 is executed to execute the auto base mode flag AB. Invert the contents of Then, the process returns to step S2, and thereafter, the processes of steps S2 to S10 are repeated. On the other hand, the interrupt signal RINT is input from the timer 5 to the CPU 4 at regular intervals. Then, every time the interrupt signal RINT is input, the CPU 4 interrupts the process being executed at that time and executes a rhythm interrupt routine shown in the flow charts of FIGS. First, the process proceeds to step S1001, where the content of the run flag RUN is "1".
It is determined whether or not. If the result of this determination is “YES”, the flow proceeds to processing from step S1002. If the decision result in the step S1001 is "NO", the rhythm interrupt routine is ended. Then, the CPU 4 resumes the interrupted processing.

<Musical instrument mode (CMFRG = 00B)> The player can select one of the pads PA1 to PAk P
When tapping the A _N, ON event of the pad switch corresponding to that pad is detected by the CPU 4. As a result, a pad switch-on event processing routine is executed in step S2 of the main routine as described below. First, the process proceeds to step S201, and it is determined whether or not the content of the code memory flag CMFRG is 10B. At the time of initialization, data 00B corresponding to the operation mode as a normal electronic musical instrument is written in the code memory flag CRDFLG, and the determination result in step S201 becomes "NO" and the
Proceed to 202. Then, send the contents of the pad number table corresponding to the pad PA _N PAD (N) is to scale sound source 9. As a result, the pad number PAD
A musical tone of a scale corresponding to (N) is generated. Then, the pad-on event processing routine ends, and the process returns to the main routine.

<Recording Mode (CMFRG = 10B)> The player turns on the record switch 206 when recording performance data. As a result, the ON event of the record switch 206 is detected by the CPU 4, and the record switch ON / OFF event processing routine is executed in step S4 of the main routine. First, the process proceeds to step S401, and it is determined whether or not an ON event is detected. In this case, the result of the determination in step S402 is "YES", the record flag REC is set to "1" (step S402), and the process returns to the main routine. Next, the player switches to song switch 20.
The switch corresponding to the number of the music piece for which the performance data is to be recorded among 2 to 204 is turned on. When the song switch ON event is detected by the CPU 4, a song switch ON event processing routine is executed in step S5 of the main routine. First, in step S501, the number corresponding to the pressed song switch is written to the variable register i based on the detected ON event. Next, the process proceeds to step S502, and it is determined whether or not the content of the record flag REC is "1". As in this case, the record flag REC is set to "1".
Is set, the result of the determination in step S502 is "YES", the flow advances to step S503, and the mode data 10B corresponding to the recording mode is written in the code memory flag CMFRG. Then, the process returns to the main routine.

The performance data can be recorded in this manner, and the player inputs the performance data by operating the pads and numeric keys as described below. First of all, the player is hit pad that corresponds to the root of the chord to be recorded, for example, the pad PA _N. As a result, the pad switch-on event of the struck pad is detected by the CPU 4, and the pad switch-on event processing routine is executed in step S2 of the main routine. First, the process proceeds to step S201, where the code memory flag CM
It is determined whether or not the content of the FLG is 10B. In this case, since CMFLG = 10B, the result of determination in step S201 is “YES”, and step S2
Go to 03. Then, the content of the number register CNT is incremented. If the current pad operation is the first pad operation, CNT =
It becomes "1". The meaning of the “first pad operation” will be described later. Next, step S204
To determine whether or not the content of the count register CNT is “1”, that is, whether or not the current pad operation is the first time. In the case of the first pad operation, step S20
4 becomes “YES”, and proceeds to the step S205, where the root note table TBLRT (i) in the ROM 6 is stored.
Reads the (i = 0~k-1) root data corresponding to the hit the pad PA _N from TBLRT (PAD (N)),
Write to root register RTBUF. The contents of the root register RTBUF are sent to the scale sound source 9. As a result,
A root sound corresponding to the pad PAN is generated by the scale sound source 9. Next, the process proceeds to step S206, and it is determined whether or not the content of the shift flag SFT is "1". At this time, if the shift switch 207 is in the off state, SFT = "0", and the determination in step S206 is "NO", and the flow proceeds to step S207. Then, it is determined whether or not the content of the count register CNT is “2” or more. In this case, the result of the determination in step S207 is “NO” and the process returns to the main routine. And
The player sure root which is pronounced, neon when those of the desired code, pads corresponding to the code type of the desired coding, for example, strike the pad PA _M. As a result, the pad switch-on event processing routine is executed again in step S2 of the main routine. In this case, when the process proceeds to step S203, the count register CN
By incrementing T, CNT = “2”
Becomes Therefore, when the process proceeds to step S204, the determination result is “NO”, and the process proceeds to step S207.
Then, it is determined whether or not the content of the count register CNT is “2” or more, that is, whether or not the current pad operation is the second or subsequent pad operation. In this case, CNT
= 2, the result of the determination in step S208 is "YES", the flow proceeds to step S208, and it is determined whether or not the content of the shift flag SFT is "1". At this time, if the shift switch 207 is in the off state, SFT = "0" and step S208
Is "NO", and the process proceeds to step S209. Then, the code type table T in the ROM 6
BLTYP [i] (i = 0~k -1) chord type data corresponding to the pads PA _M was struck from TBLTYP
(PAD (M)) and reads the code type register T
Write to YPBUF. Also, the root register RTBUF
And the contents of the chord type register TYPBUF to the scale sound source 9. As a result, the root register RTB
A chord type chord that is a root note corresponding to the contents of the UF and corresponding to the contents of the chord type register TYPBUF is generated by the scale sound source 9. Next, proceeding to step S210, "0" is written to the number register CNT, and the process returns to the main routine. By repeating the pad operation in this way, the root of the desired chord and the chord type are sequentially designated, and when the designation is completed, the count register CNT is set to "0". Then, when the pad operation is performed after CNT = “0”, the pad operation is the first pad operation for specifying the root note.

If the root sound produced by the first pad operation is not the desired one, the player presses the shift switch 207 to press another pad, for example, pad PAN _{+ 1.}
By hitting, the root note designation is redone. Less than,
The operation in this case will be described. First, the shift switch 20
7 is detected by the CPU 4, and in step S8 of the main routine, the shift switch on / off is detected.
An off event processing routine is executed. Step S8
At 01, it is determined whether or not the detected event is an ON event. In this case, the result of the determination in step S801 is “YES”, the shift flag SFT is set to “1” (step S802), and the process returns to the main routine. Next, when the pad switch-on event corresponding to the pad PAN _{+ 1} is detected by the CPU 4, the pad switch-on event processing routine is executed. In this case, since it is the second pad operation, CNT = “2” by executing step S203, and step S203 is executed.
Proceed to 204. Then, since CNT = “2”, the determination result of step S204 is “NO”, and the process proceeds to step S207. The result of the determination in step S207 is "YES", the flow proceeds to step S208, and it is determined whether or not the content of the shift flag SFT is "1". In this case, since SFT = “1”, the result of determination in step S208 is “YES”, and
Proceeding to 205, the root table TBLR in the ROM 6
Pad PA struck from T [i] (i = 0 to k-1)
Root data TBLRT corresponding to _{N + 1} (PAD _{(N +}
1)) is read and written to the root register RTBUF. The contents of the root register RTBUF are sent to the scale sound source 9. As a result, the root sound corresponding to the pad PAN _{+ 1} is generated by the scale sound source 9. Next, step S20
Then, the process proceeds to step S6, where it is determined whether or not the content of the shift flag SFT is "1". In this case, since SFT = “1”, the result of the determination in step S206 is “YES”, and the process returns to the main routine.

Then, the player confirms the newly pronounced root note. If the root note is for the desired chord,
Release the shift switch 207, pads corresponding to the code type of the desired coding, for example, strike the pad PA _M. Less than. The operation in this case will be described. First, an off event of the shift switch 207 is detected by the CPU 4, and a shift switch on / off event processing routine is executed. In this case, since the off event was detected by the CPU 4, the result of the determination in step S801 is “N”.
It becomes "O", "0" is written in the shift flag SFT (step S803), and the process returns to the main routine. Then, the pad switch-on event of the pad the pad PA _M is detected by the CPU 4, the process of step S207~S210 pad switch-on event processing routine is executed. As a result, a chord corresponding to the root note and chord type specified by the new pad operation is generated by the scale sound source 9. If the root note specified by the pad operation again is not the desired chord, the player presses the shift switch 207 again and strikes another pad. Also in this case, the pad switch-on event processing routine is executed in the same manner as described above, and the root note corresponding to the new pad is generated.

When the desired chord is generated by the scale sound source 9 and the root note and the chord type to be recorded are determined, the performer inputs the duration data. When inputting note length data corresponding to a quarter note, the performer uses the numeric keypad 2
Press the key corresponding to the numerical value "6" in 01. As a result, the numeric keypad switch-on event corresponding to the numerical value "6" is detected by the CPU 4, and a numeric keyswitch-on event processing routine is executed in step S3 of the main routine. First, proceed to step S301,
It is determined whether or not the content of the code memory flag CMFRG is 10B. CMFRG = 10B as in this case
, The determination result of step S301 is “YE
S ”, the process proceeds to step S302, and the root register R
It is determined whether or not data has been written to the TBUF and the code type register CRDTYP. If any root data and chord type data have already been written in these registers, the result of the determination in step S302 is "YES", and the flow proceeds to step S303.
Then, based on the detected keypad switch-on event, the process branches to a step corresponding to the pressed key. In this case, since the key corresponding to the numerical value "6" has been pressed, the process proceeds to step S304. Then, the address register ADRS is incremented and the code memory area CR is incremented.
The contents of the root register RTBUF and the chord type register CRDTYP are written to the DMEM (ADR) as root data and chord type data. Also, note length data corresponding to a quarter note is written to the code memory area CRDMEM (ADR), and mode data 11B corresponding to normal performance is written to the most significant 2-bit area of the code memory area CRDMEM (ADR). Next, the process proceeds to step S307, and the sound length data written in the code memory area CRDMEM (ADR) in the previous step (in this case, step S304) is accumulated in the tempo counter register TCL. Next, the process proceeds to step S308, and it is determined whether or not the content of the tempo counter register TCL has exceeded the maximum value "96" corresponding to the time length of one measure. If the determination is "Yes", the flow proceeds to step S309 to subtract "96" from the content of the tempo counter register TCL, write the result to the tempo counter register TCL, and increment the bar number register BAR by "1". I do. Then, the process proceeds to step S310. On the other hand, if the determination result in step S308 is “No”, the process proceeds to step S310 without executing step S309. Next, step S310
, The result obtained by dividing the content of the tempo counter register TCL by the count value “24” corresponding to the time length of one beat and adding “1” to the result is the beat number register BT.
Write to. Next, the process proceeds to step S311, and then proceeds to step S311 to write the contents of the measure number register BAR to the last measure number register SONG (i) corresponding to the contents of the variable register i. Next, in step S312, the contents of the bar number register BAR are written in the upper digit area of the timing register LN, the contents of the beat number register BT are written in the lower digit area, and the content of the timing register LN is displayed on the display 3. And
Return to the main routine.

On the other hand, when the player presses the key corresponding to the numerical value "7", the process proceeds from step S303 to step S303.
Proceed to 305. In this case, data corresponding to a half note is stored in the code memory area CRDMEM (A
DR). The other processing contents are the same as in the case of inputting the numerical value “6” described above. If the player has pressed the key corresponding to the numerical value "8", the process proceeds from step S303 to step S306. In this case, data corresponding to the whole note is written to the code memory area CRDMEM (ADR) as the tone length data. The other processing contents are the same as in the case of inputting the numerical value “6” described above. If the player has input a numerical value other than "6", "7" and "8", after step S303, the process returns to the main routine without performing any processing. If the content of the code memory flag CMFRG is other than 10B, the process proceeds from step S301 to step S313, performs another setting process (for example, tone color setting) based on the numeric value input on the ten keys, and returns to the main routine.

When creating performance data for an intro, fill-in or ending section, an intro /
By pressing the ending switch or fill-in switch, the mode data corresponding to the intro pattern, fill-in pattern or ending pattern is set in the code memory area CRDMEM [ADR], and the input of individual note length data of the notes constituting each pattern is performed. Can be omitted. Hereinafter, processing in this case will be described. When the player presses the intro / ending switch 209 after inputting the root note and chord type of the first chord in the performance data by operating the pad, the CPU 4 detects the intro / ending switch on event, and the main routine steps. S
At 6, an intro / ending switch-on event processing routine is executed. First, step S601
And the content of the code memory flag CMFRG is 10B
Is determined. In this case, CMFRG = 10

S ", and the process proceeds to step S602. The root register RTBUF and the chord type register CRDT
It is determined whether or not data has been written to YP. If some root data and chord type data have already been written in these registers, step S6
02 is "YES", and the result of step S603 is "YES".
The contents of the root register RTBUF and the code type register CRDTYP are stored in the code memory area CRD.
Write to the corresponding storage area in MEM (ADR). Then, the process proceeds to step S604. On the other hand, if the root note data and the chord type data are not written in the registers RTBUF and CRDTYP, the determination result in step S602 is “NO”, and the
The process proceeds to step S604 without executing 603. Next, in step S604, it is determined whether the contents of the bar number register BAR and the beat number register BT are both "1". If the result of this determination is "YES", the flow proceeds to step S605, in which the mode data 00B corresponding to the intro performance is stored in the code memory area CRDMEM.
Write to the two most significant bits of (ADR). Next, in step S606, the address register ADR is incremented by "1", and the bar number register BAR is incremented by the bar number "2" (a fixed value by factory preset) corresponding to the intro performance. Next, the process proceeds to step S607, where the contents of the bar number register BAR (in this case,
"3") is written, the content of the beat number register BT (in this case, "1") is set in the lower digit area, the content of the timing register LN is displayed on the display 3, and the process returns to the main routine. In this way, the performance data corresponding to the intro section is stored in the code memory area CRDMEM (AD
R). Thereafter, the player inputs the performance data of the third bar and the first beat after the pad operation and the ten key operation.

When the player presses the fill-in switch 208 and a fill-in switch-on event is detected by the CPU 4, a fill-in switch-on event processing routine is executed in step S9 of the main routine. First, the process proceeds to step S901, and it is determined whether or not the content of the code memory flag CMFRG is 10B. In this case, since CMFRG = 10B, the determination result of step S901 is “YES”, and the
Proceed to 902. Then, it is determined whether data is written in the root register RTBUF and the code type register CRDTYP. If some root data and chord type data have already been written in these registers, the result of the determination in step S902 is “YE

The contents of the TBUF and the code type register CRDTYP are written into corresponding storage areas in the code memory area CRDMEM (ADR). Then, the process proceeds to step S904. On the other hand, registers RTBUF and C
If the root data and the chord type data are not written in the RDTYP, the result of the determination in step S902 is “NO”, and the process proceeds to step S904 without executing step S903. Next, in step S904, it is determined whether or not the content of the beat number register BT is "1". If the determination is "YES", the flow proceeds to step S905. If the determination is "NO", that is, if the start timing of the fill-in performance does not correspond to the bar timing, the beat register BT is forcibly added to the beat register BT. "1" is set (step S906), and the process proceeds to step S905. Next, in step S905, data 01B corresponding to the fill-in pattern is written into the most significant two bits of the code memory area CRDMEM (ADR). Next, in step S907, the address register ADR is incremented by "1" and the bar number register BAR is incremented by the bar number "1" corresponding to the fill-in performance. Next, step S90
Proceeding to step 8, the contents of the bar number register BAR are written in the upper digit area of the timing register LN, and the contents of the beat number register BT are written in the lower digit area. Return. In this way, the performance data corresponding to the fill-in portion is stored in the code memory area CRDMEM (A
DR).

When the intro / ending switch 209 is pressed by the player after the performance data of the part before the ending section is created as described above, an intro / end switch ON event processing routine is executed. In this case, steps S601 to S603
Is executed, and the process proceeds to step S604, the content of the bar number register BAR is larger than "1", so that the determination result in step S604 is "NO" and the process proceeds to step S608. And beat number register B
It is determined whether or not the content of T is “1”. If this determination is "YES", the flow proceeds to step S609, and
If “NO”, that is, if the start timing of the ending performance does not correspond to the bar timing, “1” is forcibly set to the beat register BT (step S610), and the process proceeds to step S609. Next, in step S609, the mode data 10B corresponding to the ending performance is stored in the code memory area CRDME.
Write to the most significant 2-bit area of M (ADR). Next, in step S611, the address register ADR is incremented by "1" and the bar number register BAR is set to the bar number "1" corresponding to the ending pattern.

Next, in step S612, the contents of the bar number register BAR are written in the upper digit area of the timing register LN, the contents of the beat number register BT are written in the lower digit area, and the content of the timing register LN is displayed on the display unit 3. Return to routine. In this way, the performance data corresponding to the ending section is stored in the code memory area CRDMEM (AD
R).

<Reproduction Mode> When the player presses the start / stop switch, the CPU 4 executes a start / stop processing routine in step S7. First, the process proceeds to step S701, where the code memory flag CM
It is determined whether or not the content of the FRG is 10B. If the result of this determination is "No", the operation proceeds to step S702, where the contents of the run flag RUN are inverted. Then, the process returns to the main routine. If the player presses the start / stop switch in the manual step input mode, the result of the determination in step S701 is "Yes" and the process proceeds to step S703, where data 00B corresponding to the musical instrument mode is stored in the code memory flag CMFRG. Write.
Then, the process returns to the main routine. That is, when the start / stop switch is pressed in the manual step input mode, the mode is released.

When the player operates the start / stop switch and the content of the run flag RUN becomes "1", when the CPU 4 executes the rhythm interrupt routine, the judgment result in step S1001 is "Y".
es ", and proceeds to step S1002. Then, the content of the tempo counter register TCL at that time is “0” and the bar counter register BARCTR
Of the code memory area CRDMEM (ADR) designated by the address register ADR at that time is 00B. If the result of this determination is "YES", the flow proceeds to step S1020 and the intro flag IN
After writing “1” in TR, the process proceeds to step S1003. If “NO”, the process proceeds to step S1003 without executing step S1020. Here, as shown in FIGS. 5 and 6, when no performance data whose mode data is 00B is stored at all in the code memory area CRDMEM (ADR), when the rhythm interrupt routine is executed, the process proceeds to step S1002. The determination result is always "NO". On the other hand, as shown in FIG. 7, when the performance data including the mode data 00B corresponding to the intro pattern is stored in the code memory area CRDMEM (0), the rhythm interrupt routine is executed with ADR = "0". When this is done, step S1020 is executed, and INTR = "1". As a result, hereafter, 2
When the rhythm interrupt routine is executed during a period corresponding to a bar, an intro performance is performed by the processing of step S1021 and thereafter, which will be described later. Next, when the flow advances to step S1003, the content of the tempo counter register TCL becomes "96".
, That is, whether the current time is the end timing of the bar. If the result of this determination is "No", the flow proceeds to step S1021. Then, the result of adding "1" to the contents of the bar line counter register BARCTR is written to the bar number register BAR, and the result of adding "1" to the integer part of the result obtained by dividing the contents of the tempo counter register TCL by "24". To the beat number register BT. Then, the contents of the bar number register BAR and the beat number register BT are written in the display timing register LN, and the contents of the register LN are displayed on the display 3. By looking at the display on the display 3, the player can confirm at what bar and at what beat the player is currently playing.

Next, the process proceeds to step S1022, where the intro flag INTR and the fill-in flag F at that time are entered.
A rhythm sound reproduction process is performed based on the state of I and the ending flag END. That is, the intro flag I
When the NTR is “1”, the rhythm pattern (rock, waltz, etc.) specified by the rhythm switch (not shown) on the operation panel is selected from the rhythm patterns stored in the rhythm pattern area in the ROM 6. The intro pattern of the selected rhythm is selected, the data corresponding to the value of the tempo count register TCL at that time is read out of each data constituting the intro pattern, and supplied to the rhythm sound source 8. When the fill-in flag FI or the ending flag END is “1”, a pattern specified by the flag is selected from the fill-in pattern and the ending pattern, and the contents of the intro flag INTR, the fill-in flag FI and the ending flag END are all “ If it is "0", a normal pattern is selected, and the same processing as when INTR = "1" is performed. Next, the process proceeds to step S1023, and it is determined whether or not the content of the auto base mode flag AB is "1". If the result of this determination is “Yes”, the flow proceeds to step S1025, and if “No”, the flow proceeds to step S1.
Go to 024. Next, in step S1024, it is determined whether or not the content of the code memory flag CRDFRG is 01B. If the result of this determination is “Yes”, then step S
Proceed to 1025, and if “No”, step S1026
Proceed to.

Next, at step S1025, a bass sound reproduction process is performed based on the states of the intro flag INTR, fill-in flag FI and ending flag END at that time. That is, the intro flag
When INTR is "1", the rhythm type (rock, waltz, etc.) specified by the rhythm switch (not shown) on the operation panel is selected from the auto base patterns stored in the auto base pattern area in the ROM 6. Is selected, the data corresponding to the value of the tempo count register TCL at that time is read out from each data constituting the intro pattern, and is supplied to the scale sound source 9. When the fill-in flag FI or the ending flag END is “1”, a pattern specified by the flag is selected from the fill-in pattern and the ending pattern, and the intro flag INTR and the fill-in flag FI are selected.
And the contents of the ending flag END are all "0"
, A normal pattern is selected, and INTR =
The same processing as in the case of “1” is performed. Next, step S
In step 1026, it is determined whether or not the content of the code memory flag CMFRG is 01B. If the result of this determination is "YES", the flow proceeds to step S1027 and "N
If “O”, the process proceeds to step S1028.

Next, at step S1027, the chord backing sound is reproduced based on the state of the intro flag INTR, fill-in flag FI and ending flag END at that time. That is, when the intro flag INTR is "1", the chord backing intro pattern corresponding to the rhythm type designated by the rhythm switch on the operation panel is selected from the chord patterns stored in the chord pattern area in the ROM 6. And reads out the data corresponding to the value of the tempo count register TCL at that time from among the data (data designating whether or not to generate a chord sound) of the intro pattern, and determines the sound of the chord backing sound. When the instructed data is read, the root note data and the chord type data in the code memory area CRDMEM (ADR) are supplied to the scale sound source 9. Also, the fill-in flag FI or the ending flag END
Is "1", a pattern specified by the flag is selected from the fill-in pattern and the ending pattern, and the same processing as when INTR = "1" is performed. When the contents of the intro flag INTR, the fill-in flag FI and the ending flag END are all "0", the code pattern area in the ROM 6 is not referred to unlike the above-mentioned case. In this case, if the content of the tempo counter register TCL at that time matches the accumulated value of the tone length data in the reproduced performance data in the bar, the address register AD
R is incremented and the code memory area CRDME
The root note data and chord type data in the M (ADR) are sent to the scale sound source 9, and the chord memory area CRDME
New pitch data is read from M (ADR) and added to the accumulated value of the pitch data up to that time. Here, when the accumulated value of the duration data exceeds “96”, the accumulated value is changed to “9”.
6 "is subtracted. Next, proceeding to step S1028, the content of the tempo counter register TCL is incremented, and the rhythm interrupt routine ends.

Thereafter, every time a predetermined time elapses, the rhythm interrupt routine is executed as described above. And
When the CPU 4 executes the rhythm interrupt routine,
If the content of the tempo counter register TCL is "96", the result of the determination in step S1003 is "Yes", and the flow advances to step S1004. Next, step S1004
Then, "0" is written to the tempo counter register TCL, and the contents of the bar line counter register BARCTR are incremented. Next, the process proceeds to step S1005,
It is determined whether the intro flag INTR is “1” and the content of the bar line counter register BARCTR is “2”. If the result of this determination is “YES”, the flow advances to step S1006 to set INTR = “0”. When step S1006 ends, step S1 is executed.
Proceed to 007. On the other hand, if the decision result in the step S1005 is “NO”, the process proceeds to the step S1007 without executing the step S1006. If the mode data corresponding to the intro performance is not stored in the code memory area as shown in FIGS. 5 and 6, step S100
The determination result of No. 5 is always “NO”. In contrast, FIG.
As shown in the figure, mode data 0 corresponding to the intro performance
If 0B is stored in the code memory area, INTR = "1" when the mode data is read out.
(Step S1020), and thereafter, during a period corresponding to two measures, step S10 of the rhythm interrupt routine is performed.
The intro performance is performed by performing the processing after 21. Rhythm interrupt routine is executed and 2
When the playback of the intro with a bar ends, INTR =
"1" and BARCTR = "2", and step S1
005 is “YES” and INTR
= "0" (step S1006), and the intro performance ends.

Then, the flow advances to step S1007 to determine whether or not the content of the bar counter register BARCTR is smaller than the bar number stored in the last bar number register SONG (i) by "1". If the result of this determination is “NO”, the flow proceeds to step S1010. On the other hand, if the result of the determination in step S1007 is “Yes”, the flow proceeds to step S1008, where the code memory area C specified by the current address register ADR is read.
It is determined whether or not the mode data 10B corresponding to the ending pattern exists in the RDMEM (ADR). If the result of this determination is “Yes”, step S1009
And writes "1" in the ending flag END, and proceeds to step S1010. As a result, after that, during the period corresponding to one bar, the ending performance is performed by performing the processing after step S1021 of the rhythm interrupt routine. On the other hand, if the result of the determination in step S1008 is “No”, the process proceeds to step S1010 without executing step S1009. in this way,
When the performance data including the mode data 10B corresponding to the ending pattern is stored in the code memory area as the performance data corresponding to the last measure, the performance data one bar before the performance data is read out. END = "1".

Next, in step S1010, it is determined whether or not the contents of the measure line count register BARCTR match the contents of the last measure number register SONG (i). If the result of this determination is “No”, the flow proceeds to step S1015. On the other hand, if the result of the determination in step S1010 is “Yes”, the flow advances to step S1011 to write “0” into the bar line counter register BARCTR and the address register ADR. Next, step S
Proceeding to 1012, it is determined whether the content of the code memory flag CMFRG is 01B. The result of this determination is “N
If “O”, the process proceeds to step S1015. On the other hand, if the result of the determination in step S1012 is “YES”, the flow proceeds to step S1013, where the code memory area CRDMEM (A) specified by the address register ADR is set.
DR), that is, in this case, it is determined whether or not the mode data 00B corresponding to the intro pattern is stored in CRDMEM (0). If the result of this determination is “NO”, the flow proceeds to step S1015. On the other hand, if the result of the determination in step S1013 is “YES”, the flow proceeds to step S1014, and the bar line counter register BACT
“2” is written to R, the address register ADR is incremented by “1”, and the process proceeds to step S1015. As described above, when the performance data corresponding to the intro performance is stored in the code memory area CRDMEM (0), after the reproduction of the performance data of the last bar is completed, the A
DR is set to "1", and reproduction is performed from the performance data next to the performance data corresponding to the intro performance. That is, the performance is repeated, bypassing the intro performance.

Next, in step S1015, it is determined whether or not the content of the end flag END is "1". If the result of this determination is "NO", the above-described processing from step S1021 is executed, and the rhythm interrupt routine ends. On the other hand, if the result of the determination in step S1015 is “YES”, the flow proceeds to step S1016,
"0" is written to the ending flag END and the run flag RUN, and the bar line counter register BAR is written.
Write "0" to CTR. Then, the rhythm interrupt routine ends. When the performance data including the mode data 10B corresponding to the ending performance is stored in the code memory area as the performance data corresponding to the last measure, before the ending performance of one measure based on the performance data is started. END is set to "1" (step S1009). Then, when END = "1" and the ending performance ends, RUN = "0" (step S1016), and the automatic performance stops. On the other hand, the mode data 10 corresponding to the ending performance
If the performance data including B is not stored in the code memory area, writing “1” to the ending flag END (step S1009) is not executed.
Therefore, when the reproduction of the performance data corresponding to the last bar is completed, ADR is set to "0" (step S101).
1) The music data is reproduced again in order from the first performance data in the code memory area.

As described above, at each bar line timing, it is determined whether or not the performance data to be reproduced in the bar corresponds to the ending pattern (step S1008), and the determination result is "Yes". In this case, an instruction to start the ending performance is given at the bar timing (step S1009). Therefore, even if the sum of the tone length data before the ending part is not an integral multiple of the time length of one measure, the ending performance is started at the measure line timing of the last measure.
For example, if the performance data having the length data corresponding to two beats is erroneously recorded as the performance data corresponding to the fourth beat immediately before the last bar, the performance data is recorded at the time of reproduction by one beat. And the ending performance is started at the bar timing of the last bar. As a result, it is possible to prevent the performance from being erroneously performed in an irregular time signature.

Next, the operation when the fill-in switch is pressed during the period in which the automatic performance is being performed will be described. In this case, when the CPU 4 executes the fill-in switch-on event processing routine, the code memory flag CMFRG is used.
Is written with data other than 10B, the result of the determination in step S901 is "NO" and the
Proceeding to 911, it is determined whether the run flag RUN is "1". The result of this determination is "YES" and the flow proceeds to step S912 to set "1" to the fill-in flag FI. As a result, in steps S1022 and S1025 of the rhythm interrupt routine, the ROM 6
, A rhythm accompaniment and an auto-bass accompaniment based on the fill-in pattern are performed.

Next, the operation when the intro / ending switch is depressed during the automatic performance is described. Also in this case, when the CPU 4 executes the intro / ending switch-on event processing routine, since data other than 10B is written in the code memory flag CMFRG, the result of the determination in step S601 is “NO” and the result in step S621 is “NO”. To determine whether the run flag RUN is "1". In this case, the result of the determination in step S621 is "YES", the flow proceeds to step S623, and the ending flag END is set to "1".
Is set. As a result, in steps S1022 and S1025 of the rhythm interrupt routine, RO
The ending pattern is read from M6, the ending performance is performed, and then the automatic performance ends.

When automatic performance is not performed and writing to the code memory area is not performed (CMFRG).
The operation when the intro / ending switch is depressed to (a value other than 10B) will be described. In this case, step S624 is executed via steps S601 and S621 of the intro / ending switch on event processing routine, and INTR = "1" and RUN = "1". As a result, when the rhythm interrupt routine is executed, the processing after step S1002 is executed. Here, since INTR = "1", step S102
At 2 and S1025, an intro pattern is read from the ROM 6, and an intro performance is performed. In addition,
In the above embodiment, the case where the intro pattern is fixed to two measures and the ending pattern is fixed to one measure has been described.
The length of each of these patterns is not limited to this, and can be set arbitrarily.
