The process then proceeds to the event write preprocessing routine via step S97, writes an LTI command for setting an interval time to the song memory 7, and then proceeds to the event write routine. In this case, steps 5363, 5364 and 5380 are executed via steps 5351, 5352, and the key code register KC and key speed register KV are
Writes a KOFF command with the contents of as an operand to the fifth channel of the song memory 7,
Increment T(5). Then, the process returns to the main routine via the event write preprocessing routine, key-off processing routine, and key processing routine. In this manner, each time a key-on event, a key-off event, or a key-off event of the keyboard L is detected, the detected event is sequentially written into the fifth channel of the song memory 7 as operation information of the first track of the melody demo section. During this time, the metronome sound is generated at time intervals according to the tempo set in the tempo register TEMPO, so the performer can play the keyboard L according to the set tempo while listening to the metronome sound. Operation information is written to the song memory 7 in real time. Note that the recording of other melodies on the second to fifth tracks is also executed by the process described above. ◎Each musical tone signal output from the first to fourth channels in the recording tone generator TG of the vector synthesizer section (first to fourth tracks) is sent to the left speaker and right speaker R at a distribution rate set for each valley channel. distributed. That is, musical tones with different sound image positions are generated by each musical tone signal output from the first to fourth channels. Therefore, by adjusting the intensities of the musical tone signals generated from the first to fourth channels, a musical tone at a desired sound image position can be obtained. This MIDI sequencer can record operation information for reproducing musical tones in which the sound image position dynamically changes according to the above principle in the vector synthesizer section of the song memory 7, that is, in the first to fourth channels. can. The operation in that case will be explained below. The performer turns on both the recording switch SW9 and the track instruction switch SW6. As a result, as in the case of recording the first melody track described above, the process proceeds from the main routine to the vector synthesizer processing routine via the key processing routine and switch processing routine. Then, since the recording switch SW9 is turned on, step 5221,
5231, the recording standby flag RECWAIT is set (step 5234), the recording channel register WC is set to rlJ (step 5233), and the sixth state register 5TATE (6) is set to "3" (recording mode). Then, the process returns to the main routine via the switch processing routine and the key processing routine. After that, the same process as in the case of recording the first melody track described above is performed, the recording flag RECORD is set, the recording mode is entered, and from then on, the metronome sound is generated at the tempo according to the setting of the tempo register TEMPO. along with beat register BEAT and measure number register MEΔ5
URE is updated. When the performer turns on any key on the keyboard L, the process proceeds to the key-on processing routine via the key processing routine, sets the key code for the key-on event in the key code register KC (step 571), and records the velocity information of the key. speed and set it on the disk KV (step 572). Then, the determination result in step S73 is rY
E S J, the process advances to step S78, and "1" is set in the channel number register CH. By the way, this MIDI controller generates information for controlling the sound image position of musical tones generated by operating the joystick 3, and this control information is used in the processing from step S79 onwards. Therefore, step S79
Before explaining the subsequent processing, the processing from detecting the amount of operation of the joystick 3 to creating information for controlling the sound image position will be described below. When the joystick processing routine (FIG. 8) is started in step S3 of the main routine, step 5
Proceeding to step 501, the operation amount information in the X-axis direction and the operation amount information in the Y-axis direction of the joystick 3 output from the A/D converter 4 are taken into operation amount registers X and Y, respectively. And right to the manipulated variable register X! After bit shift processing (step S502), the content of the manipulated variable register within the range. Similar processing is performed for the manipulated variable register Y (steps 5505 to 5507). Then, steps 5508 to 5511 are executed, and the calculations shown in the following equations (+) to (4) are performed to calculate the coefficient A-D. A=(3EII-Y)+l X-1r'll+...

It can be expressed as x+Qcy −(7) D=Qcx+Qdy −−(8). That is, the above formulas (1) to (4)
By calculating the target sound image position P specified by the manipulated variable registers X and Y, the first
-Coefficients A-D are obtained according to the distances to the respective sound image positions PA-PD corresponding to the fourth channel. Then, steps 5512 to 5515 are executed to calculate the following equations (9) to (I2). Each song memory 7
Volume information VOL corresponding to the 1st to 4th channels of

1) VOL (4) = VOLTBL (D) (
12) Here, the table VOLT13L stores a table that takes into consideration the dependence of the amplitude of musical tones on the distance from the sound source. As a result, for example, in the case of volume information VOL(1), the larger the coefficient A is, that is, the farther the target sound image position PA is from the sound image position PA of the first tone, the smaller the value is set. The volume information VOL(2) to VOL(4) are similarly set, and the volume is set according to the target sound image position P. In the process after step S79 of the key-on process routine, the volume information at the time obtained by the joystick process routine ■0L(1) to VOL
Using (4), information is written to the vector synthesizer section as described below. First, the process proceeds to step S79, where the volume information VO specified by the channel register CH at that time
Set L(CH) (in this case, VOL(1)) to the volume write register VOLW. Next, the process advances to step S80, where the write channel register WC
The value rlJ of channel register CH is set to . Next, the process advances to step S81 to open the operation register.
The code of the channel pressure command CPreS is set to . Then, the process proceeds to the event write preprocessing routine via step S82, writes an LTl command indicating the interval time until the next event to the first channel of the song memory 7 (steps 5331-9335), and proceeds to the event write routine. . And step 5351-S3

Execute and set channel point POINT(1) to N=
The process advances by 2 and returns to the key-on processing routine via the event write preprocessing routine. Then, the process proceeds to step S83, where the channel register CH
A channel pressure command CP res and volume write information VOLW are sent to the first channel of the tone generator TG specified by , and the volume of the first channel is set. Next, the process advances to step S84, and the operation register o
The code of the key-on command KOH is set to P, and the process advances to step S85 to execute the event write preprocessing routine. As a result, the same processing as described above is performed, and the LT+ instruction and the contents of the key code register K (, D, and key speed register KV are used as operands) Key-on command KON
is written. Next, the process proceeds to step 686, and a key-on command KON is sent to the first channel of the tone generator TG using the contents of the key code register KCD and key speed register KV as operants. Then, the process proceeds to step S87, where the channel register CH is incremented, and the process proceeds to step 988, where it is determined whether or not CH=5.
The result is NOJ and the process returns to step S79. Then, by repeating steps S79 to S88 described above, the volume information VOL(2) to vOL(4) is stored in the second and third channels in the song memory 7.
A channel pressure command corresponding to each channel is written, and a KON command with the same key code and velocity as that written to the first channel is written. Also, the same command written to the first to fourth channels of the song memory 7 is written to the first to fourth channels of the tone generator TG.
A musical tone having a sound image position specified by operating the joystick 3 is generated. When CH=5, the determination result in step S88 becomes rYE, sJ, and the process returns to the main routine via the key processing routine. When the performer keys off the keyboard L, the process proceeds to the key off processing routine (FIG. 11) via the key processing routine, sets the key code in the key code register KCD (step 591), and sets the key release speed in the key speed register KV. After setting step 592), the process proceeds to step S9B via step S93. Then, rlJ is set in channel register CI. Then, the key-off command K is sent to the operation register OP.
Set the code of OF'F (step 599), then start the event write preprocessing routine and write the LTI instruction, key code register KCD, and key speed register KV.
A key-off command KOFF having each of the contents as operands is written into the first channel of the song memory 7 (step 5100). Then, the key-off command KO'FF, which is the same as that written in the first channel of the song memory 7, is sent to the first channel of the tone generator TG to stop producing the musical tone (step S I 01 ). Then, in step 5I, the channel register CH is incremented.
02), step S103) determines whether CH=5, and if the determination result is rNOJ, performs steps 999 to 5103 described above according to the new channel number CH.
Execute. In this way, the key-off command KOFF is written into the first to fourth channels of the song memory 7 and sent to the first to fourth sound generation channels of the tone generator TG, thereby stopping the generation of musical tones.

[Playback mode]

When the performer turns on the play switch 5WI2 of the operation panel 2, the play processing routine shown in FIG. 12 is activated via the key processing routine and the switch processing routine. First, proceed to step 5ttt and set the play flag PLAY.

, and set "16" in the playback channel register PC. Next, the process proceeds to step 5114, where the count value of the time counter MC at that point in time is set in the channel timing register CCNT(PC) (in this case, CCN'r(+6)) specified by the reproduction channel register PC. Also, the channel pointer POINT (PC) specified by the playback channel register PC is set to "0".
is set, and the reproduction channel register PC is further decremented. Next, the process advances to step 5115, and it is determined whether PC=O or not. In this case, the determination result is rNOJ and the process returns to step 5114. Then, step 5114 is executed for PC=15 to l, and when PC=0 by executing step 5114, the judgment result of step 5115 becomes [YESJ, and step 51
Proceed to step 16. Then, enter “1” in the playback channel register PC.
6'' is set, the process proceeds to step 5117, and the semantic interpretation processing routine shown in FIG. 13 is executed. First, the process proceeds to step 5121, where the channel pointer PO[NT(PC) of the channel specified by the playback channel register PC (in this case, the 16th channel) is referenced, its contents are set as the next address, and the data is retrieved from the song memory 7. Read 1 word and write operation register O
Import into P. Next, the process advances to step 5122, where it is determined whether the instruction code stored in the operation register OP is an LTI instruction. In the case of this MIDI sequencer, the code of the TOR instruction that specifies the tempo of the song is stored at the start address of the 16th channel of the song memory. Therefore, the determination result is rNOJ, and the process proceeds to step 5123, where it is determined whether the instruction code is for all MM instructions. The result of this judgment is also rNOJ, and the process proceeds to step 5124. And the instruction code is 'r o
Determine whether it is the n instruction or not, and the determination result is 1YE.
S'' and the process proceeds to step 5134. Then, the channel pointer PotNT (PCX
However, 2 words of data are read from the address obtained by adding 2 to PC=16) and set in the tempo register TEMPO. Next, the process advances to step 5135, sets "4" to the instruction length register N, and advances to step 5140, where the channel pointer POINT (PC) (in this case, POIN
Increase the contents of T(16)) by N=4. and,
The play processing routine, switch processing routine, and key processing routine are sequentially performed, and the process returns to the main routine. Then, the process advances to step S3 to execute a joystick processing routine, and then to step S4 to execute a sequencer processing routine. When proceeding to the sequencer processing routine, the play flag PLA
Since only Y is in the set state, steps S51 and S5
2, the process advances to step S55, and the sequencer play routine shown in FIG. 14 is executed. First, the process proceeds to step 5151, where "16" is set in the playback channel register PC. Next, the process proceeds to step 5152, where the channel timing register CCNT(PC) of the channel specified by the playback channel register PC is entered.
It is determined whether or not (in this case, CCNT(16)) is less than or equal to the count value of the time counter MC at that time. Then, if the judgment result is rY E S J, step 5
Proceeds to I53, executes the semantic analysis processing routine, and returns "NO".
”, skip step 5153 and proceed to step 5.
Proceed to 154. When the semantic analysis processing routine is activated, data is read from the song memory 7 in step 5121 as described above, and the data is stored in the operating register OP1. : After being stored, step S! The instruction code is determined by the determination of 22 to 5129, and processing according to the instruction is performed. When an LTI instruction (interval time load instruction) is fetched, the process passes through step 5122 to step 5131.
Proceed to. Then, the upper bit data II of the interval time written in the operand part of the imported LTI instruction
and the lower bit data ii, and the time counter MC at that time, MO+256XI
The calculation I+ii is performed. Then, the calculation result, that is, the next time to execute the instruction corresponding to the channel PC, is stored in the channel timing register CCNT (PC).
Set to . Next, the process proceeds to step 5132, where "3" is set in the instruction length register N, and the process proceeds to step 5140, where the channel pointer POINT (PC) is incremented by N=3. If you import a command to declare all MM command measure changes,
Step 5133 via Step 5122.5123
Step 5140 sets the instruction length register N to "3". That is, in this case, only the channel pointer POINT (PC) is incremented. The case of the TOR instruction has already been explained, so a redundant explanation will not be given. If a KON command (key-on command) is imported, proceed to step S! The process proceeds to 5141 via steps 22 to 5126, and it is determined whether the play flag PLAY is set. If the judgment result is "NO", the process advances to step 5142, and then to step 5137, where the state register of track i corresponding to the channel PC is referred to, and 5TATE (
i) In the case of −1, that is, when the reproduction of the track i is prohibited, the velocity information of the key velocity register KV. rOJ and proceeds to step 5137. On the other hand, if the determination result in step 5141 is rY E S J, step 5142 is skipped and the process proceeds to step 5137 . Then, in step S1' 37, "3" is set in the instruction length register N, and then the process proceeds to step 5139, where N=3 words of data are read from the song memory 7, and the subsequent data, that is, the key-on instruction code,
The key code and velocity information of the tone to be produced are sent to the channel PC in the tone generator TG. As a result, a musical tone corresponding to the KON command is generated in the channel PC. In the case of a KOFF instruction (key-off instruction), the process proceeds to step 5137 via steps 8122 to 5127, and 13'' is set in the instruction length register N. Next, the process advances to step 5139, where the data from the song memory 7 is
= 3 words are read and the subsequent data, ie, the code of the key-off command, the key code of the sound to be muted, and the velocity information, are sent to the channel PC in the tone generator TG. As a result, generation of musical tones corresponding to the KOFF command is stopped. If a CP res instruction (channel pressure instruction) is taken in, the process proceeds to step 5126 via steps 5122 to 5125, sets "2" to the instruction length register N, and proceeds to step 5139. Then, N = 2 words of data are read from the address indicated by the channel pointer POINT (PC) in the song memory 7, and the successive data, that is, the channel pressure instruction code and its parameters are specified by the playback channel register PC in the tone generator TG. Send to the pronunciation channel that will be used. Here, the channel pressure commands created by operating the joystick 3 as described above are stored in the first to fourth channels of the song memory 7 as key-on commands.
It is recorded along with the key-off command, etc. Therefore, when the playback channel register PC becomes "1" to "4" and the channel pressure commands are taken out from the first to fourth channels of the song memory 7, these will cause the reproduction channel registers PC to be set to "1" to "4", and the channel pressure commands will be taken out from the first to fourth channels of the song memory 7. The volume is controlled, and a musical tone whose sound image position changes according to the operation of the joystick 3 during self-recording is reproduced. In the case of the ChordC instruction, steps 5122~
5128 to steps 5137 and 5139;
A chord according to the imported Chord C command is generated by the tone generator TG. Then, when the EOE command is fetched, step 5121-
Proceed to step 5138 via step 8129, set rlJ in instruction length register N, and proceed to step 5I39.5I4.
Execute 0. In this way, commands are fetched from the channel specified by the playback channel register PC in the song memory 7 and executed. When the semantic analysis processing routine ends and the program returns to the sequencer play routine, proceeding to step 5154, the playback channel register PC is decremented. Next, the process advances to step 5155, where it is determined whether PC=0 or not. If the determination result is "NO", the process returns to step 5152. In this way, the commands stored in the channel PCs in the song memory 7 are fetched and executed for PC=16 to l. The sequencer play routine is then terminated, and the process returns to the main routine via the sequencer processing routine. In this way, the MIDI information stored in the song memory 7 is played back, but if the performer operates the keyboard L during playback, when the key processing routine is executed, the key-on processing routine or key-off processing The routine is executed and a musical tone corresponding to the key operation is generated.

[Recording and playback mode]

For example, the performer turns on both the track instruction switch SWI and the recording switch SW9, and then turns on the play switch 5W1.
When 2 is turned on, each process in the recording mode and each process in the playback mode described above are executed together, and the operation information recorded in each channel of the song memory 7 is played back to generate musical sounds, and the operation event of the keyboard 1 is also executed. A recording/playback mode for recording to the fifth channel in real time is executed.

[Stop recording and playback]

To end recording or playback, the performer turns on the stop switch 9W11. As a result, when the switch processing routine is started sequentially through step S2 of the main routine and the line processing routine, steps S20 to S
22, the process advances to step S32, and a stop processing routine shown in FIG. 24 is executed. If this MIDI sequencer operates in recording mode and the recording flag RECORD is set, step 542

427), a switch processing routine, and a line processing routine, and then returns to the main routine. On the other hand, even in the playback mode, the stop switch 5W11
By turning on, a stop processing routine is started in the same way as for the above-mentioned recording, and playback is ended. However, in this case, the recording flag RECORD is in the reset state, so
When executing the stop processing routine, steps 8422 to 5
425 is not executed.

[Measure number operations]

This MIDI sequencer can advance the measure number in the measure number register MEASURE or return it to the beginning of the song when it is not in the recording mode. To advance the measure number, the performer presses the measure advance switch 5W.

It is determined whether the instruction is a FOR instruction. If the determination result is rNOJ, that is, the instruction is not an EOR instruction for all MM instructions, the process returns to step 5636. On the other hand, if the determination result in step 5638 is rYEsJ, that is, the instructions taken into the operation register OP are all MM instructions, the channel register CF is decremented (step 5644), and it is determined whether cH=0 (step 5644). If the judgment result is rNOJ, step 8636
Go back and do the above for the new channel,

Next, the channel register CH is decremented (step 5641), CH
=O or not (step 5642). If the judgment result is rNOJ, step 8636
If rYESJ, the process returns to the measure forwarding routine. In this way, for each channel CI-1, unless a FOR instruction is detected in the middle, the channel pointer (CH) is incremented until all MM instructions that declare measure switching are detected, and a FOR instruction is detected in the middle. In this case, the channel pointer POINT(CH) is returned to the state before processing. Then, the process returns to step 562 and returns to the measure advance processing routine.
Proceed to step 3, determine whether there is a measure after the current measure number, and if the judgment result is rNOJ, change the current measure number register MEΔ5URE to the measure number indicator DIS.

In this way, each channel pointer POINT (CH) is incremented for each channel CI until the measure set in the measure number register MEASURE is searched. Then, the process returns to the measure return processing routine, and step 868
Proceed to step 5, display the measure number register MEASURE on the measure number display DISr'l, and execute the switch processing routine.
Return to the main routine via the key processing routine. In this way, the performer can operate the measure number by operating the measure forward switch 5WI3 and the measure backward switch 5W14, and can play back the operation information stored in the song memory 7 from a desired measure number. I can do it,
Further, operation information can be recorded starting from a desired measure number. Furthermore, in the case of this MIDI sequencer, unless the recording flag RECORD is set, requests for manipulating bar numbers are accepted, so it is possible to change bar numbers during playback.

[Tempo operation]

When this MIDI sequencer is not in the recording mode, it can speed up the tempo by turning on the tempo up switch 5W15, and slow it down by turning on the tempo down switch 5W16. That is, when the tempo up switch 5W15 is turned on, the process proceeds to the tempo up-chin shown in FIG. 30 via the key processing routine and the switch processing routine. Then, it is determined whether the recording flag RECORD is set or not (step 5801), and if the determination result is "NO", it is determined whether the tempo register TEMPO has reached the upper limit value r250J of the child keyboard (step 5803), If the determination result is "NO", the tempo register TEMPO is incremented. Further, when the tempo down switch 5W16 is turned on, the process proceeds to the tempo up-chin shown in FIG. 31, and it is determined whether or not the recording flag RECORD is set (step 5804). is the lower limit of tempo “30”
In step S805), if the result of the determination is "NO", the tempo register TEMPO is
Decrement. In this way, the tempo set in the tempo register TEMPO is changed, and according to the changed tempo, metronome sound generation, measure number switching timing control, etc. are performed. "Effects of the Invention" As explained above, according to the present invention, an automatic performance recorder includes an operator for instructing generation of a desired musical tone, and records operation information of the operator on a recording medium as automatic performance information. In the apparatus, means for recording operation information corresponding to the desired musical tone on the recording medium as a plurality of pieces of automatic performance information each corresponding to a different sounding means, an effect operator for instructing a desired performance effect, and the effect Since control information for controlling each musical tone generated by the plurality of pieces of automatic performance information is generated in accordance with the amount of operation of the operator and is recorded on the recording medium, the control information generated by the operation information is generated during playback. This has the advantage that it is possible to change the musical tones that are played, and it is possible to perform automatic performances with rich performance effects.
