In this state, real-time code input is performed by playing the performance data from the code memory area CRDMEM and updating the contents of the code memory area CRDMEM by code input.

The operation of this electronic musical instrument will be described below with reference to the flow charts shown in FIGS. When the power switch 301 of this automatic musical instrument is turned on, C
The PU 4 executes a main routine whose flow is shown in FIG. First, in step S1, initial values are set in the control registers and flags in the RAM 6. Next, in step S2, if an ON event of any of the pad switches in the pad switch group 1 is detected at that time, a pad switch processing routine whose flow is 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 point, a ten key ON event processing routine whose flow is shown in FIG. 10 is executed. Next, in step S4, if an ON event or an OFF event of the record switch 206 is detected at that point, a record switch ON / OFF event processing routine whose flow is 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 point, a song switch ON event processing routine whose flow is shown in FIG. 12 is executed. Next, in 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 whose flow is shown in FIG. 13 is executed. Next, in step S7, if the on-event of the start / stop switch 210 is detected at that time, the start / stop switch on-event processing routine whose flow is shown in FIG. 14 is executed. Next, the process proceeds to step S8, and if the ON event of the shift switch 207 is detected at that time, the process shown in FIG.
The shift switch on / off event processing routine showing the flow is executed. Next, proceeding to step S9, if an ON event of the fill-in switch 208 is detected at that point, a fill-in switch ON / OFF event processing routine whose flow is shown in FIG. 16 is executed. Next, in step S10, if an on event of an auto base switch (not shown) is detected at that point, an auto base switch on event processing routine whose flow is shown in FIG. 17 is executed to set the auto base mode flag AB. Invert the contents of. Then, the process returns to step S2, and thereafter, each processing of steps S2 to S10 is 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 point and executes the rhythm interrupt routine shown in the flow charts of FIGS. 18 and 19. First, in step S1001, the content of the run flag RUN is "1".
Determine whether or not. If the result of this determination is "YES", then the flow proceeds to the processing in and after step S1002. If the decision result in the step S1001 is "NO", the rhythm interrupt routine is ended. Then, the CPU 4 restarts the interrupted process.

<Musical instrument mode (CMFRG = 00B)> The performer selects one of the pads P1 to PAk from the pads P1 to PAk.
When A _N is hit, the ON event of the pad switch corresponding to that pad is detected by the CPU 4. As a result, the pad switch on event processing routine is executed in step S2 of the main routine as described below. First, in step S201, it is determined whether or not the content of the code memory flag CMFRG is 10B. At the time of initialization, the data 00B corresponding to the operation mode as a normal electronic musical instrument is written in the chord memory flag CRDFLG, and the result of the determination in step S201 is "NO" and step S201.
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 is generated by the scale sound source 9.
A musical tone of a scale corresponding to (N) is produced. Then, the pad-on event processing routine is ended and the process returns to the main routine.

<Recording Mode (CMFRG = 10B)> When the performer records performance data, the performer turns on the record switch 206. 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, in step S401, it is determined whether or not the detected event is an on event. In this case, the determination result of step S402 is "YES", the record flag REC is set to "1" (step S402), and the process returns to the main routine. Next, the performer uses the song switch 20
Of the Nos. 2 to 204, the switch corresponding to the number of the piece of music for which performance data is to be recorded is turned on. When the ON event of the song switch is detected by the CPU 4, the 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 in the variable register i based on the detected ON event. Next, in step S502, it is determined whether the content of the record flag REC is "1". As in this case, the record flag REC has "1".
If is set, the determination result of step S502 is “YES”, the process proceeds 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.

In this way, the performance data can be recorded, and the performer inputs the performance data by operating the pad and ten 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 hit 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, in step S201, the code memory flag CM
It is determined whether the content of FLG is 10B. In this case, since CMFLG = 10B, the determination result of step S201 is "YES", and step S2
Go to 03. Then, the content of the frequency 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
Then, it is judged whether or not the content of the number-of-times register CNT is "1", that is, whether or not the pad operation this time is the first time. In the case of the first pad operation, step S20
The determination result of No. 4 is “YES”, the process proceeds to step S205, and the root note table TBLRT (i) in the ROM 6
Reads the (i = 0~k-1) root data corresponding to the hit the pad PA _N from TBLRT (PAD (N)),
Write to the root register RTBUF. Further, the contents of the root register RTBUF are sent to the scale sound source 9. As a result,
A root note corresponding to the pad PAN is generated by the scale sound source 9. Next, in step S206, it is determined whether the content of the shift flag SFT is "1". If the shift switch 207 is off at this time, SFT = "0", and the result of the determination in step S206 is "NO", and the process proceeds to step S207. Then, it is determined whether or not the content of the frequency register CNT is “2” or more. In this case, the determination result of step S207 is "NO", and the process returns to the main routine. And
The performer checks the sounded root note, and if the root note is of a desired chord, hits a pad corresponding to the chord type of the desired chord, for example, 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 number 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 number-of-times 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
Since the judgment result of step S208 becomes "YES" from the time of "= 2", the process proceeds to step S208 to judge whether or not the content of the shift flag SFT is "1". If the shift switch 207 is off at this point, SFT = "0" is set, and step S208 is performed.
The determination result 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)) is read and the code type register T
Write to YPBUF. Also, the root register RTBUF
And the contents of the chord type register TYPBUF are sent to the scale tone generator 9. As a result, the root register RTB
A chord type chord corresponding to the contents of the UF and corresponding to the contents of the chord type register TYPBUF is sounded by the scale sound source 9. Next, in step S210, "0" is written in the number register CNT, and the process returns to the main routine. By repeating the pad operation in this manner, the root note and the chord type of the desired chord are sequentially designated, and when the designation is completed, the frequency register CNT is set to "0". When a pad operation is performed after CNT = “0” in this way, the pad operation is the first pad operation for designating the root note.

If the root note produced by the first pad operation is not the desired one, the performer presses the shift switch 207 to another pad, for example pad PA _{N + 1.}
By tapping, the root note is specified again. Less than,
The operation in this case will be described. First, the shift switch 20
The on event of No. 7 is detected by the CPU 4, and the shift switch is turned on / on in step S8 of the main routine.
The off-event processing routine is executed. Step S8
It is determined whether or not the event detected at 01 is an on event. In this case, the determination result of step S801 is "YES", the shift flag SFT is set to "1" (step S802), and the process returns to the main routine. Next, the pad switch on event processing routine is executed by the CPU 4 detecting the pad switch on event corresponding to the pad PA _{N + 1} . In this case, since it is the second pad operation, CNT = “2” is obtained by executing step S203, and step S203
Proceed to 204. Then, since CNT = “2”, the determination result of step S204 becomes “NO”, and the process proceeds to step S207. The determination result in this step S207 is "YES", and the process proceeds to step S208 to determine whether or not the content of the shift flag SFT is "1". In this case, since SFT = "1", the determination result of step S208 is "YES" and step S208.
Step 205, root note table TBLR in ROM6
Pad PA struck from T [i] (i = 0 to k-1)
Root data TBLRT corresponding to _{N + 1} (PAD _{(N +}
1)) is read out and written in the root register RTBUF. Further, the contents of the root register RTBUF are sent to the scale sound source 9. As a result, the root note corresponding to the pad PA _{N + 1} is generated by the scale sound source 9. Next in step S20
In step 6, it is determined whether the content of the shift flag SFT is "1". In this case, since SFT = “1”, the determination result of step S206 is “YES” and the process returns to the main routine.

Then, the performer confirms the newly pronounced root note. If the root note is of 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 CPU 4 detects an off event, the determination result of 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, the chord corresponding to the root note and chord type designated by the new pad operation is produced by the scale sound source 9. If the root note re-designated by another pad operation is not the one of the desired chord, the performer further presses the shift switch 207 and taps 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 sounded.

When the desired chord is produced by the scale tone source 9 and the root note and chord type to be recorded are determined, the performer inputs the note length data. When inputting the 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 CPU 4 detects the ten key switch on event corresponding to the numerical value "6", and the ten key switch on event processing routine is executed in step S3 of the main routine. First, go to step S301,
It is determined whether or not the content of the code memory flag CMFRG is 10B. As in this case CMFRG = 10B
If it is, the determination result of step S301 is “YE
S ”, and the process proceeds to step S302, where the root register R
It is determined whether or not data is written in the TBUF and the code type register CRDTYP. When some root note data and chord type data are already written in these registers, the determination result of step S302 is "YES", and the process proceeds to step S303.
Then, based on the detected ten-key switch-on event, the process branches to the 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
The contents of the root note register RTBUF and the chord type register CRDTYP are written to the DMEM (ADR) as root note data and chord type data. Further, note length data corresponding to a quarter note is written in the chord memory area CRDMEM (ADR), and mode data 11B corresponding to a normal performance is written in the most significant 2-bit area of the chord memory area CRDMEM (ADR). Next, proceeding to step S307, the tone length data written in the chord memory area CRDMEM (ADR) in the previous step (step S304 in this case) is accumulated in the tempo counter register TCL. Next, in step S308, it is determined whether or not the content of the tempo counter register TCL exceeds the maximum value "96" corresponding to the time length of one bar. If the result of this determination is "Yes", the flow proceeds to step S309, "96" is subtracted from the contents of the tempo counter register TCL, the result is written to the tempo counter register TCL, and the measure number register BAR is incremented by "1". To do. Then, the process proceeds to step S310. On the other hand, if the determination result of step S308 is “No”, then step S309 is not executed and the process proceeds to step S310. Next in step S310.
When the operation proceeds to step 1, the result of adding "1" to the result of dividing the content of the tempo counter register TCL by the count value "24" corresponding to the time length of one beat is the beat number register BT.
Write in. Next, proceeding to step S311, next proceeding to step S311, the contents of the bar number register BAR are written to the final bar number register SONG (i) corresponding to the contents of the variable register i. Next, in step S312, the content of the bar number register BAR is written in the upper digit area of the timing register LN, the content of the beat number register BT is written in the lower digit area, and the content of the timing register LN is displayed on the display unit 3. And
Return to the main routine.

On the other hand, if the performer presses the key corresponding to the numerical value "7", steps S303 to S303 are performed.
Proceed to 305. In this case, data corresponding to a half note is used as the note length data in the chord memory area CRDMEM (A
DR). The other processing contents are the same as in the case of inputting the numerical value "6" described above. When the performer presses the key corresponding to the numerical value "8", the process proceeds from step S303 to step S306. In this case, the data corresponding to all the notes is written in the chord memory area CRDMEM (ADR) as the note length data. The other processing contents are the same as in the case of inputting the numerical value "6" described above. When the performer inputs a numerical value other than the numerical values "6", "7" and "8", after step S303, the process returns to the main routine without performing any processing. When the content of the chord memory flag CMFRG is other than 10B, the process proceeds from step S301 to step S313, another setting process (for example, tone color setting) is performed based on the numeric keypad input, and the process returns to the main routine.

When creating performance data for the intro section, fill-in section or ending section,
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 chord memory area CRDMEM [ADR], and the individual note length data of the notes that make up each pattern is input. It can be omitted. The processing in this case will be described below. When the performer inputs the root note and chord type of the first chord in the performance data by operating the pad and then presses the intro / ending switch 209, the CPU 4 detects an intro / ending switch on event, and the steps of the main routine are executed. S
At 6, the intro / ending switch on event processing routine is executed. First, step S601
And the content of the code memory flag CMFRG is 10B.
Or not. In this case, CMFRG = 10
Since it is B, the determination result of step S601 is "YE
S ”, and the process proceeds to step S602. Then, the root register RTBUF and the chord type register CRDT
It is determined whether or not data is written in YP. If some root note data and chord type data are already written in these registers, step S6.
The determination result of 02 is “YES” and step S603.
To the chord memory area CRD and the contents of the root register RTBUF and the chord type register CRDTYP.
Write in the corresponding storage areas in the MEM (ADR). Then, the process proceeds to step S604. On the other hand, when the root note data and the chord type data are not written in the registers RTBUF and CRDTYP, the determination result of step S602 is “NO”, and step S602 is executed.
The process proceeds to step S604 without executing 603. Next, proceeding to step S604, it is determined whether or not 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, and the mode data 00B corresponding to the intro performance is stored in the code memory area CRDMEM.
Write to the most significant 2 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" (fixed value by factory preset) corresponding to the intro performance. Next, in step S607, the contents of the bar number register BAR (in this case, the upper digit area of the timing register LN)
"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 chord memory area CRDMEM (AD
R). After that, the performer inputs the performance data on and after the first beat of the third measure by operating the pad and ten keys.

When the performer presses the fill-in switch 208 and the fill-in switch-on event is detected by the CPU 4, the fill-in switch-on event processing routine is executed in step S9 of the main routine. First, in step S901, it is determined whether 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 step S901
Proceed to 902. Then, it is determined whether or not data is written in the root note register RTBUF and the chord type register CRDTYP. If some root note data and chord type data are already written in these registers, the judgment result of step S902 is "YE".
S ”, and the process proceeds to step S903, and the root register R
The contents of the TBUF and the code type register CRDTYP are written in the corresponding memory areas in the code memory area CRDMEM (ADR). Then, the process proceeds to step S904. Meanwhile, registers RTBUF and C
When the root note data and the chord type data are not written in RDTYP, the determination result of step S902 is "NO", and step S903 is not executed and the process proceeds to step S904. Next, proceeding to step S904, it is determined whether or not the content of the beat number register BT is "1". If the result of this determination is "YES", the flow proceeds to step S905, and if it is "NO", that is, if the start timing of the fill-in performance does not correspond to the bar line timing, the beat register BT is forced to " 1 ”is set (step S906), and the process proceeds to step S905. Next, proceeding to step S905, the data 01B corresponding to the fill-in pattern is written in the most significant 2 bits of the code memory area CRDMEM (ADR). Next, in step S907, the address register ADR is incremented by "1" and the measure number register BAR is incremented by "1", which is the number of measures corresponding to the fill-in performance. Then in step S90
8, the content of the bar number register BAR is written in the upper digit area of the timing register LN, the content of the beat number register BT is written in the lower digit area, the content of the timing register LN is displayed on the display unit 3, and the main routine is executed. Return. In this way, the performance data corresponding to the fill-in part is stored in the chord memory area CRDMEM (A
DR).

When the performer presses the intro / ending switch 209 after the performance data of the portion before the ending portion is created as described above, the intro / ending switch on event processing routine is executed. In this case, steps S601 to S603
Since the contents of the bar number register BAR are larger than "1" when the process is executed to step S604, the determination result of step S604 becomes "NO" and the process proceeds to step S608. And beat number register B
It is determined whether the content of T is "1". If the result of this determination is “YES”, the flow proceeds to step S609,
If "NO", that is, if the ending performance start timing does not correspond to the bar line timing, "1" is forcibly set in 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 chord memory area CRDME.
Write to the area of the most significant 2 bits 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 content of the bar number register BAR is written in the upper digit area of the timing register LN, the content of the beat number register BT is 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 part is stored in the chord memory area CRDMEM (AD
R).

<Playback Mode> When the performer presses the start / stop switch, the CPU 4 executes a start / stop processing routine in step S7. First, in step S701, the code memory flag CM
It is determined whether the content of FRG is 10B. If the result of this determination is "No", the flow advances to step S702 to invert the contents of the run flag RUN. Then, the process returns to the main routine. When the performer presses the start / stop switch in the manual step input mode, the determination result of step S701 is "Yes" and the process proceeds to step S703, and the data 00B corresponding to the musical instrument mode is set to the chord 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 content of the run flag RUN becomes "1" by the player operating the start / stop switch, when the CPU 4 executes the rhythm interrupt routine, the determination result in step S1001 is "Y".
es ”and the process proceeds to step S1002. The content of the tempo counter register TCL at that time is "0" and the bar counter register BARCTR
Is "0", and it is determined whether the upper 2 bits of the code memory area CRDMEM (ADR) designated by the address register ADR at that time are 00B. If the result of this determination is "YES", the flow proceeds to step S1020 and the intro flag IN
After writing “1” to TR, the process proceeds to step S1003, and if “NO”, the process proceeds to step S1003 without executing step S1020. Here, as shown in FIG. 5 and FIG. 6, when the performance data whose mode data is 00B is not stored in the chord memory area CRDMEM (ADR) at all, when the rhythm interrupt routine is executed, step S1002 is executed. The judgment 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 chord 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, 2
When the rhythm interrupt routine is executed for a period corresponding to a bar, the intro performance is performed by the processing of step S1021 and subsequent steps described later. Next, proceeding to step S1003, the content of the tempo counter register TCL is "96".
Or not, that is, whether or not the present 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 content 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 of dividing the content 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 this register LN are displayed on the display unit 3. By looking at the display on the display unit 3, the performer can confirm what measure and what beat the player is currently playing.

Next, in step S1022, the intro flag INTR and the fill-in flag F at that time are set.
Rhythm sound reproduction processing is performed based on the state of I and the ending flag END. That is, the intro flag F
When I is “1”, it corresponds to the rhythm type (lock, waltz, etc.) specified by the rhythm switch (not shown) on the operation panel from among the rhythm patterns stored in the rhythm pattern area in the ROM 6. The intro pattern of the selected rhythm is selected, and the data corresponding to the value of the tempo count register TCL at that time point is read out from the respective data forming the intro pattern and supplied to the rhythm sound source 8. When the fill-in flag FI or the ending flag END is "1", the pattern designated by the flag is selected from the fill-in pattern and the ending pattern, and the intro flag IN
When the contents of TR, fill-in flag FI and ending flag END are all "0", the normal pattern is selected, and the same processing as in the case of INTR = "1" is performed. Next, proceeding to step S1023, it is determined whether or not the content of the auto base mode flag AB is "1". If this determination result is “Yes”, the process proceeds to step S1025, and if “No”, the process is step S102.
Go to 4. Next, proceeding to step S1024, it is determined whether the content of the code memory flag CRDFRG is 01B. If the result of this determination is "Yes", then step S10.
25, and if “No”, the process proceeds to step S1026.

Next, proceeding to step S1025, bass tone reproduction processing is performed based on the states of the intro flag INTR, fill-in flag FI and ending flag END at that time. That is, when the intro flag FI is "1", the rhythm type (lock) specified by the rhythm switch (not shown) on the operation panel is selected from the auto bass patterns stored in the auto bass pattern area in the ROM 6. , Waltz, etc.) is selected, and the data corresponding to the value of the tempo count register TCL at that point in time is read out from each of the data forming the intro pattern and supplied to the scale tone generator 9. Further, the fill-in flag FI or the ending flag END is "1".
If it is, select the pattern specified by the flag from the fill-in pattern and ending pattern,
When the contents of the intro flag INTR, the fill-in flag FI and the ending flag END are all "0", the normal pattern is selected, and the same processing as in the case of INTR = "1" is performed. Next, step S1026.
And the contents of the code memory flag CMFRG is 01.
It is determined whether or not it is B. This judgment result is "YES"
In the case of, it progresses to step S1027, and in the case of "NO", it progresses to step S1028.

Next, in step S1027, the chord backing sound is reproduced based on the states of the intro flag INTR, fill-in flag FI and ending flag END at that time. That is, when the intro flag FI is “1”, the chord backing intro pattern corresponding to the rhythm type designated by the rhythm switch of the operation panel from among the chord patterns stored in the chord pattern area in the ROM 6 Is selected, and the data corresponding to the value of the tempo count register TCL at that point in time is read out from each data (data designating whether or not to generate a chord tone) that constitutes the intro pattern, and the chord backing tone is produced. When the instructed data is read, the root note data and the chord type data in the chord memory area CRDMEM (ADR) are supplied to the scale tone source 9. When the fill-in flag FI or the ending flag END is "1", the pattern specified by the flag is selected from the fill-in pattern and the ending pattern, and the same process 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 case. In this case, if the contents of the tempo counter register TCL at that point of time and the accumulated value of the tone length data in the reproduced performance data in the measure match, the address register AD
R is incremented and code memory area CRDME
The root note data and chord type data in M (ADR) are sent to the scale tone generator 9, and chord memory area CRDME
New tone length data is read from M (ADR) and added to the accumulated value of the tone length data up to that point. Here, if the cumulative value of the tone length data exceeds "96", the cumulative value becomes "9".
6 ”is subtracted. Next, proceeding to step S1028, the contents of the tempo counter register TCL are incremented and the rhythm interrupt routine is ended.

Thereafter, the rhythm interrupt routine is executed as described above each time a predetermined time has elapsed. And
When the CPU 4 executes the rhythm interrupt routine,
If the content of the tempo counter register TCL is "96", the determination result of step S1003 becomes "Yes" and the process proceeds to step S1004. Next step S1004
When the process advances to step 1, "0" is written to the tempo counter register TCL and the bar line counter register BARCTR is incremented. Next, in 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
Proceed to 007. On the other hand, when the result of the determination in step S1005 is "NO", step S1006 is not executed and the process proceeds to step S1007. If the mode data corresponding to the intro performance is not stored in the chord memory area as shown in FIGS. 5 and 6, step S100
The judgment result of 5 is always "NO". On the other hand, FIG.
As shown in, mode data 0 corresponding to the intro performance
If 0B is stored in the code memory area, INTR = "1" at the time when the mode data is read.
(Step S1020), and thereafter, during a period corresponding to two measures, step S10 of the rhythm interrupt routine.
The intro performance is performed by performing the processing after 21. Rhythm interrupt routine is executed 2
When the playback of the intro section with a bar ends, INTR =
“1” and BARCTR = “2”, and step S1
The determination result in 005 is “YES”, and INTR
= “0” is set (step S1006), and the intro performance ends.

Next, in step S1007, it is determined whether or not the content of the bar line counter register BARCTR is smaller than the bar number stored in the final 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, and the code memory area C specified by the address register ADR at the current time point.
It is determined whether or not there is the mode data 10B corresponding to the ending pattern in the RDMEM (ADR). If the result of this determination is "Yes", then step S1009.
In step S1010, "1" is written in the ending flag END, and the flow advances to step S1010. As a result, after that, the ending performance is performed by performing the processing after step S1021 of the rhythm interrupt routine for a period corresponding to one bar. On the other hand, if the determination result of step S1008 is “No”, step S1009 is not executed and the process proceeds to step S1010. in this way,
When the performance data including the mode data 10B corresponding to the ending pattern as the performance data corresponding to the final measure is stored in the chord memory area, the performance data one bar before the performance data is read out. Is set to END = “1”.

Next, in step S1010, it is determined whether the contents of the bar line count register BARCTR match the contents of the final bar 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" in the bar line counter register BARCTR and the address register ADR. Then step S
In step 1012, it is determined whether the code memory flag CMFRG is 01B. This judgment result is "N
If “O”, the process proceeds to step S1015. On the other hand, if the decision result in the step S1012 is “YES”, the process advances to a step S1013, and the code memory area CRDMEM (A designated by the address register ADR.
DR), that is, in this case, 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 decision result in the step S1013 is "YES", the process advances to a step S1014, and the bar line counter register BACT.
"2" is written in 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 chord memory area CRDMEM (0), after the reproduction of the performance data of the last measure is finished,
DR = “1” is set, and reproduction is performed from the performance data next to the performance data corresponding to the intro performance. That is, the intro performance is bypassed and the performance is repeated.

Next, proceeding to step S1015, it is determined whether or not the content of the ending flag END is "1". If the result of this determination is "NO", then the processes in and after step S1021 described above are executed and the rhythm interrupt routine is terminated. On the other hand, if the result of the determination in step S1015 is “YES”, the process proceeds to step S1016,
"0" is written to the ending flag END and the run flag RUN, and the bar line counter register BAR
Write "0" in CTR. Then, the rhythm interrupt routine ends. In this way, when the performance data including the mode data 10B corresponding to the ending performance is stored in the chord memory area as the performance data corresponding to the last measure, before the ending performance of one measure by the performance data is started. END = “1” is set (step S1009). Then, when END = "1" and the ending performance ends, RUN = "0" (step S1016) and the automatic performance is stopped. On the other hand, mode data 10 corresponding to the ending performance
If the performance data including B is not stored in the chord 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 measure is finished, ADR = "0" is set (step S101).
1) Again, the performance data is reproduced in order from the first performance data in the code memory area.

As described above, at each bar line timing, it is judged whether the performance data to be reproduced in the bar corresponds to the ending pattern (step S1008), and the judgment 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 total sum of the sound length data before the ending portion is not an integral multiple of the time length of one bar, the ending performance is started at the bar line timing of the last bar.
For example, when the performance data having the note length data corresponding to 2 beats is mistakenly recorded as the performance data corresponding to the 4th beat immediately before the last measure, the performance data is reproduced with the note length of 1 beat. The ending performance is started at the bar line timing of the last measure. As a result, it is possible to prevent accidental and unreasonable time signature performance.

Next, the operation when the fill-in switch is pressed while 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
Since data other than 10B is written in, the determination result of step S901 is "NO" and step S901 is executed.
In step 911, it is determined whether the run flag RUN is "1". The result of this determination is "YES", and the flow advances to step S912 to set "1" in the fill-in flag FI. As a result, in steps S1022 and S1025 of the rhythm interrupt routine, the ROM 6
The fill-in pattern is read from the rhythm and the rhythm accompaniment and auto-bass accompaniment are performed by the fill-in pattern.

Next, the operation when the intro / ending switch is pressed while the automatic performance is being performed will be described. Also in this case, when the CPU 4 executes the intro / ending switch on event processing routine, since the data other than 10B is written in the code memory flag CMFRG, the determination result of step S601 becomes "NO" and step S621. Then, it is determined whether the run flag RUN is "1". In this case, the determination result of step S621 is “YES”, the process proceeds to step S623, and the ending flag END is set to “1”.
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 the automatic performance is not performed and the writing to the chord memory area is not performed (CMFRG
When the intro / ending switch is pressed to a value other than 10B), the operation will be described. In this case, step S624 is executed through 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 from step S1002 onward is executed. Here, since INTR = "1", step S102
2 and S1025, the intro pattern is read from the ROM 6 and the intro performance is performed. In addition,
In the above embodiment, the case where the intro pattern is fixed to 2 bars and the ending pattern is fixed to 1 bar has been described.
The length of each of these patterns is not limited to this, and can be set arbitrarily.
