Description

[Detailed description of the invention] [Industrial application field] The present invention relates to electronic musical instruments.
The present invention relates to an electronic musical instrument having various automatic performance functions.

[Conventional technology]

2. Description of the Related Art Some conventional electronic musical instruments such as electronic keyboard instruments write automatic performance information generated by a player's performance of music in a predetermined storage area and read out the automatic performance information written in the storage area as necessary to read the music. Is provided with an automatic performance function for playing back music.

Generally, in order to enable automatic performance of a plurality of types of music, an electronic musical instrument having this type of automatic performance function generally instructs writing and reading of the automatic performance to and from a predetermined storage area for each of the plurality of types of music. There are multiple automatic performance channels available. Writing and reading of automatic performance information to and from each automatic performance channel is performed by selecting a specific automatic performance channel from a plurality of automatic performance channels, and operating only one start / stop switch in this state. Have been done.

[Problems to be solved by the invention]

In the case of an electronic musical instrument having this kind of automatic performance function, the reproduction control of a plurality of automatic performance information can be performed at the same time, but the start and end of the reproduction of the plurality of automatic performance information cannot be controlled independently. is there. For example, the reproduction of the automatic performance information written to the channel 2 is started while the automatic performance information written to the channel 1 is being reproduced, and in this state, the reproduction of the automatic performance information written to the channel 1 is terminated halfway. I couldn't do that.

Apart from these drawbacks, in the automatic performance function of the conventional electronic musical instrument, the automatic performance information written to a plurality of automatic performance channels is uniquely reproduced according to the automatic performance information at the time of writing. It is, of course, impossible to reproduce the automatic performance information once written in the storage area while shifting the pitch (frequency) or the like. However, this problem can be solved by using the transpose function added to the electronic musical instrument.However, if this transpose function is used, the pitch during normal performance, which is not automatic performance, will be shifted, and the above automatic performance will be shifted. When performing along with the performance, inconvenience occurs.

Also, in the automatic accompaniment device, by pressing any key, a code set in advance for that key allows
In some cases, an automatic performance is performed, but in this case, since the accompaniment pattern is fixed in advance, the automatic accompaniment is monotonous.

It is an object of the present invention to provide an electronic musical instrument capable of reproducing a plurality of pre-written automatic performance information while changing a pitch or the like, thereby performing a variety of automatic performances.

[Means for solving the problem]

The present invention is applied to an electronic musical instrument having an automatic performance recording mode for recording automatic performance information and an automatic performance reproduction mode for reproducing the automatic performance information recorded in the automatic performance recording mode.

The means of the invention according to claim 1 is as follows.

The plurality of performance operators specify at least a pitch, and include, for example, keys of a keyboard instrument.

The storage means stores automatic performance information including a plurality of tone data including pitch data input by operating a plurality of performance operators for designating pitches.
A normal performance information storage area for storing normal performance information which is composed of an M (random access memory), a RAM card, or the like, and is read out only once in response to an operation of a performance operator as described in claim 4. And a repetition performance information storage area for storing repetition performance information that can be repeatedly read.

The setting means sets the write start address of the automatic performance information to be written to the storage means in the automatic performance recording mode, corresponding to the performance operator operated immediately before writing the automatic performance information to the storage means.

The writing means writes automatic performance information including pitch difference data indicating a pitch difference between a pitch designated by an operated performance operator and a predetermined reference pitch.
As described in claim 4, in the automatic performance recording mode, the pitch difference data of the first tone and the last tone of the automatic performance information of the automatic performance information written in the normal performance information storage area by operating the performance operator. Only when the height difference data is equal, the automatic performance information stored in the normal performance information storage area is written as repeated performance information in the repeated performance information storage area, and the write start address set by the setting means is set to the The address is changed to an address in the repetition performance information storage area, and the others are written in the normal performance area. The reference pitch is, for example, a pitch written to a write start address of the storage means.

The reproducing means reproduces the music based on the automatic performance information including the pitch difference data, and when an arbitrary performance operation is operated immediately after switching to the automatic performance reproduction mode, the first pitch of the music to be reproduced is reproduced. Is set, and the pitches of the subsequent songs are set based on the initial pitch and the pitch difference data stored in the storage means. In reproducing the music, for example, when a predetermined performance operation element for generating a musical tone having a predetermined pitch is operated, the first musical tone of the music is changed to the predetermined performance. When the pitch is higher than a predetermined value, the pitch difference data is read from the repetition performance information stored in the repetition performance area, and otherwise, the pitch difference data is read. Pitch difference data is read from the normal performance information stored in the normal performance area, and the second and subsequent musical tones of the music are reproduced at a pitch based on the read pitch difference data and the first pitch. In setting the pitch of the music to be reproduced, for example, in the automatic performance reproduction mode, the pitch corresponding to the performance operator operated first is set to the initial pitch. .

Further, the means according to claim 6 further includes the following means in addition to the means of the invention.

The foot operator is an operator operated by a player's foot operation, and includes, for example, a pedal switch such as a damper pedal switch or a soft pedal switch.

The control means reads the pitch difference data from the storage means when detecting the stop of the operation of the performance operator after the foot operation is performed while reading the pitch difference data from the storage means. Further, for example, as described in claim 7, after the operation of the performance operator is stopped after the foot operation of the foot operator, the reading of the pitch difference data from the storage means is continued. While you are
If the foot operation of the foot control is detected again,
The reading of the pitch difference data from the storage means is stopped.

[Action]

First, the operation of the means of the first invention is as follows.

First, when the mode of the electronic musical instrument is switched to the automatic performance recording mode, the setting means sets the writing start address of the automatic performance information to be written in the storage means to an arbitrary performance operated immediately before writing the automatic performance information to the storage means. Set according to the operator. Then, after the writing start address is set by the setting means, an arbitrary music piece is played while operating the performance operator, and the writing means operates the sound specified by the operated arbitrary performance operator. The tone data including the pitch difference data indicating the pitch difference between the pitch and the predetermined reference pitch is repeated when the pitch data of the first tone and the pitch data of the last tone of the music piece are equal. The information is repeatedly written as performance information in the repeated performance information storage area in the storage means.

Therefore, in the automatic performance recording mode, repetitive performance information including a plurality of tone data including pitch difference data that can be used repeatedly is stored in the storage means.

Next, when an arbitrary performance control is operated after the mode of the electronic musical instrument is switched to the automatic performance playback mode, the playback means operates the predetermined performance control for generating a musical tone having a predetermined pitch. In this case, the first musical tone of the music is reproduced at the pitch related to the predetermined performance operator, and then the pitch difference data is read out from the repetitive performance information stored in the repetitive performance information storage area. The second and subsequent tones of the music are reproduced at the pitch based on the pitch difference data.

Therefore, in the automatic performance reproduction mode, the performance information including the pitch difference data which can be used repeatedly written in the automatic performance recording mode is read out individually in accordance with the operation of the performance operator, and the read out is performed. Based on the pitch difference data included in the automatic performance information, the automatic performance information is reproduced with, for example, a change in pitch or the like corresponding to the operated performance operator.

Further, according to the present invention, in the automatic performance reproduction mode, the stop of the operation of the performance operator is detected after the foot operator is operated while the pitch difference data is being read from the storage means. If so, reading of the pitch difference data from the storage means is continued.

Therefore, the reproduction of the automatic performance by the reproducing means can be continued by operating the foot operator.

Further, while the stop of the operation of the performance operator is detected after the foot operation of the foot operator and the reading of the pitch difference data is continued from the storage means, the foot operation is performed again. When the child's foot operation is detected, the reading of the pitch difference data from the storage means can be stopped.

The keyboard 2 sends musical tone information such as pitch, volume, key ON information, initial touch information, after touch information, and key OFF information of a musical tone to the CPU 12 in accordance with a player's key pressing operation. The effect switch group 6 sends to the CPU 12 musical tone information such as a tone or an effect to be added to a generated musical tone in response to a player operation. The CPU 12 generates various tone control information from the various tone information transmitted from the keyboard 2 and the tone / effect switch group 6 and sends the information to the tone generator 16. The tone generator 16 receives various tone control information input from the CPU 12. The digital tone signal is generated based on the information and sent to the D / A converter 17.

The D / A converter 17 performs D / A conversion of a digital tone signal transmitted from the tone generator 16 and sends an analog tone signal obtained by this conversion to the amplifier 18 of the tone generator 19.

 Next, details of the storage area of the RAM 15 will be described.

 FIG. 3 is a diagram showing a storage area of the RAM 15.

As shown in the figure, the RAM 15 has a sequencer start address STAD write area 21 starting from address 1000,
Sequence data write area starting from address 2000 22
Has two storage areas.

Of these, the sequence data write area 22 starting at address 2000 is an automatic data area consisting of pitch data, key ON data, key OFF data, note length data, and the like of musical tones related to automatic performance in the sequencer write mode of the sequencer mode. This is an area where performance information is written in correspondence with a key depression operation of each key on the keyboard 2. The sequencer start address STAD write area 21 starting from address 1000
It is divided into individual storage area 21a corresponding to 37 keys of the pitch provided in semitones from C ₂ of the keyboard 2 to C _5, the segmented storage area 21a into their individual In the sequencer write mode of the sequencer mode, a write start address (STAD) of a series of automatic performance information to be written in the sequence data write area starting at address 2000 is written.

That is, the 37 keys of the pitch of C _{2 to} the keyboard 2 to C _5, are assigned corresponding storage area 21a, when writing of automatic performance information for RAM15 in the sequencer recording mode, the sequencer In the write mode, the address STAD is written to the storage area 21a of the sequencer start address STAD write area 21 at address 1000 or later corresponding to the key pressed together with the operation of the sequencer write SW8, and the address 2000 or later. The automatic performance information is sequentially written from the address STAD of the sequence data writing area 22 of FIG.

Operation Next, the operation of the electronic keyboard instrument of the first embodiment having the above configuration will be described.

In this electronic keyboard instrument, in the sequencer writing mode of the sequencer mode, when a player first presses any key on the keyboard 2 to record a music piece related to automatic performance, the key is depressed. RAM15 assigned to key
Sequencer start address STAD write area 21
Sequencer start address STAD in storage area 21a
In this state, when the player presses a key on the keyboard 2 to play a tune related to the automatic performance, sequence data for automatic performance generated according to the performance of the tune related to the automatic performance is set. Is the sequencer start address ST
Sequence data write area 22 specified by AD
Are sequentially written from this address.

Then, in the sequencer playback mode of the sequencer mode, the written sequence data is used to record an arbitrary key on the keyboard 2 which is first pressed to record a song related to automatic performance in the sequencer writing mode of the sequencer mode. By pressing a key, the sequencer start address set in the STAD write area 21 of the RAM 15 assigned to the depressed key is set.
Reproduction is performed sequentially from the corresponding address in the sequence / data write area 22 specified by the address STAD.

The writing and reproduction of the sequence data are realized by the CPU 12 performing a sequencer SW scan process, a sequencer write process, a sequencer reproduction process, and a pedal SW scan process described below.

Sequencer SW scan processing Sequencer SW scan processing is an interrupt processing performed by the CPU 12 in response to an interrupt generated at a predetermined cycle. The CPU 12 periodically detects the state of the performance mode switching switch 7 and the sequencer writing SW8 to perform the performance of the electronic keyboard instrument. This is a process of setting the mode to any one of the sequencer reproduction mode, the sequencer write mode, and the sequencer write standby mode.

FIG. 4 is a flow chart for explaining the sequencer SW scan processing performed by the CPU 12.

In this sequencer SW scan processing, it is determined whether the performance mode set by the operation of the performance mode switch SW7 is the normal mode or the sequencer mode, and the sequencer set by the operation of the sequencer write SW8. Write mode and sequencer write
The sequencer writing standby mode set by the simultaneous operation of SW8 and an arbitrary key of the keyboard 2 is determined. Then, in order to determine each of these modes, the CPU 12
In the scanning process, a sequencer mode flag ("1" in the sequencer mode) indicating that the performance mode is the sequencer mode, a sequencer write SW8
Sequencer write SW / ON flag ("1" when sequencer write SW8 is ON) indicating that the performance mode is ON state, and a sequencer write mode flag ("1" indicating that the play mode is the sequencer write mode) "1" in the sequencer writing mode) and a sequencer recording flag indicating that the sequencer is recording (writing) ("1" when the sequencer is recording) are used.

As shown in the figure, in the sequencer SW scan processing, first, the status (ON / OFF state) of the performance mode switching SW7 in which the CPU 12 is switched by the player's operation.
Is started (S1).

If it is determined that the performance mode switch SW7 is not ON and the performance mode is set to the normal mode, the CPU 12 next refers to a sequencer playback flag (not shown) indicating that the sequencer is being played. Then, it is further determined whether or not the sequencer is playing (S2).
If it is determined that reproduction is not being performed, the process returns to the main routine (RET).

On the other hand, if it is determined in step S2 that the sequencer is playing, after performing control to stop playback of the sequencer (S3), various flags of the sequencer (sequencer mode flag, sequencer write SW / ON flag, Reset the sequencer writing mode flag, sequencer writing standby mode flag, and sequencer recording flag) (S4),
Return to the main routine (RET).

By the above operation, when the performance mode switching SW7 is continuously set to the normal mode side in the normal mode, the performance mode remains unchanged in the normal mode. On the other hand, when the performance mode switch SW7 is switched to the normal mode in the sequencer reproduction mode, the performance mode is immediately switched from the sequencer reproduction mode of the sequencer mode to the normal mode.

On the other hand, in the process S1, the performance mode switch SW7 is turned on.
If it is determined that the state is the performance mode and the performance mode is set to the sequencer mode, then it is further determined whether or not the sequencer mode flag is "1" (S5).

Here, if the sequencer mode flag is “0” instead of “1”, the CPU 12 sets the sequencer mode flag to “1” (S6), and then executes the next process.
If the sequencer mode flag is "1" in the determination process S5, the process immediately proceeds to the next process S7.

When the performance mode switch SW7 is switched to the sequencer mode in the normal mode by the above operation, the performance mode is switched from the normal mode to the sequencer mode.

After the performance mode is set to the sequencer mode in the processing S6, or when the sequencer mode flag is already set to “1” in the processing S5, the CPU 12
Next, it is further determined whether or not the sequencer write SW8 is in the ON state (S7). And sequencer writing SW8 is O
If it is in the N state, the CPU 12
After setting the flag to "1" (S8), it is determined whether or not a sequencer recording flag set by a sequencer reproduction process S27 (see FIG. 5) described later is "1" (S9). If the sequencer recording flag is not set to "1", the process immediately returns to the main routine (RET).

By the above operation, when the sequencer write SW8 is turned on in the sequencer mode, the sequencer / write S
The W / ON flag is set to "1".

On the other hand, in the above process S7, the sequencer write SW8 is turned on.
If the status is not the status but the status is OFF, the CPU 12 determines whether or not the sequencer write SW / ON flag is "1" (S10). When the sequencer write SW / ON flag is "0" instead of "1", the process immediately returns to the main routine (RET).
The PU 12 resets the sequencer write SW / ON flag to “0” (S11).

By the above operation, when the sequencer write SW8 changes from "OFF" to "ON" in the sequencer mode, the sequencer write SW / ON flag is set to "1".

In the process S10, the sequencer write SW
If the flag is "0" instead of "1", the sequencer write SW8 remains "OFF" and has not changed, so that the process immediately returns to the main routine (RET).

Next, in the process S11, the sequencer write SW
When the flag is reset to "0", the CPU 12 further determines whether or not the sequencer write mode flag set in the sequencer reproduction process S27 described later is set to "1" (S12). If the sequencer write mode flag is set to “1”, the CP
U12 sets the sequencer write standby mode flag to "1" and then turns the LED 10 on and off (S13), and further resets the sequencer write mode flag to "0" (S1).
4) Return to the main routine (RET).

By the above operation, when the sequencer write SW8 changes from "ON" to "OFF" in the sequencer write mode, the performance mode is switched from the sequencer write mode to the sequencer write standby mode. As will be described later, the sequencer writing mode is set by newly pressing any key on the keyboard 2 while the sequencer writing SW8 is set to “ON” in the sequencer mode. ,
By turning off the sequencer writing SW8, the performance mode is switched from the sequencer writing mode to the sequencer writing standby mode. When the performance mode is switched from the sequencer writing mode to the sequencer writing standby mode, the LED 10 changes to a blinking state indicating that the mode has been switched from the sequencer writing mode to the sequencer writing standby mode.

On the other hand, if the sequencer recording flag is set to "1" in the process S9, the CPU 12 resets the sequencer recording flag to "0" (S15), and the LED 10
Is turned off (S16), and the process immediately returns to the main routine (RET).

By the above operation, the sequencer write SW8 is pressed after the writing of the automatic performance information to the RAM 15 is completed, and "ON"
Then, the performance mode switches from the sequencer recording mode to the sequencer mode, and the LED 10 lights up.
From “off” to “off”.

By the above-described sequencer SW scan processing, the performance mode of the electronic keyboard instrument can be set to each of the sequencer playback mode, the sequencer write mode, the sequencer write standby mode, and the sequencer recording mode by operating the performance mode switch SW7 and the sequencer write SW8. Is set to one of the modes.

Sequencer writing process The sequencer writing process is a process for detecting various key-pressing operation states of each key of the keyboard 2 periodically by an interruption process performed by the CPU 12 at a predetermined cycle, and for various automatic performances inputted by the key-pressing operation. This is a process of writing the sequence data in the sequence data write area 22 of the RAM 15.

FIGS. 5A to 5E are flow charts for explaining the sequencer writing process performed by the CPU 12. FIG.

In this sequencer writing process, the CPU 12
Pedal SW ON flag indicating that the pedal SW5 is in the ON state ("1" when it is in the ON state), and sequencer playback processing
A continue flag ("1" when continuing) indicating that S27 is to be continued is used.

As shown in the figure, first, the CPU 12 reads the key press information of each key of the keyboard 2, and temporarily stores (stores) the read key press information in the work area of the RAM 15 (S17). Next, the CPU 12 determines whether or not the sequencer recording in progress flag is “1” (S18). If the sequencer recording in progress flag is “0”, the CPU 12 stores the current press stored in the RAM 15 in the process S17. Based on the key information and the previous key press information stored in the RAM 15 in the process S17 at the time of the previous interrupt, it is further determined whether or not there is a newly pressed key (S19). Then, when there is a newly pressed key, the CPU 12 next determines whether or not the sequencer write SW / ON flag is “1” (S20).

Then, when the sequencer write SW / ON flag is “1”, the CPU 12 determines whether or not the sequencer mode flag is “1” (S20-1). If the sequencer mode flag is "1", the sequencer write mode flag is set to "1" (S2
1) Further, the sequence data for automatic performance is written to the sequencer start address STAD write area 21 of the RAM 15 previously allocated to the newly depressed key determined in the process S19. After writing the start address (sequencer start address STAD) of the sequence data write area 22 (S2
2) Return to the main routine (RET). If the sequencer mode flag is "0" in the above processing S20-1, the process returns to the main flow (RET).

By the above operation, when any key of the keyboard 2 is pressed while the sequencer writing SW8 is turned on in the sequencer mode, the mode is switched from the sequencer mode to the sequencer writing mode, and the performer newly presses the key. In the sequencer start address STAD write area 21 of the RAM 15 assigned to the key in advance,
The sequencer start address STAD is written.

That is, as shown in FIG. 6 showing a usage example of the storage area of the RAM 15, for example, in the sequencer mode, the key that is depressed together with the ON operation of the sequencer writing SW 8 is
^# Is the key to _4, hereinafter, sequence data for automatic performance input in response to a key depression operation of the keys of the keyboard 2, a start address of the sequence data write area 22 "20
When starting from address 00, the sequencer start address STAD assigned to the F ^# ₄ key
“2000 address” is written in the storage area 21a of the writing area 21. Further, the same when the key is the key depression is another key, such as G ₄ and G ^# _4, the storage area 21a of the sequencer start address STAD write area 21 assigned to each key Then, "2000" and "2300" which are the write start addresses of the sequence data for automatic performance in the sequence data write area 22 are written.

In the figure, F ^# ₄ and to the storage area 21a of the G ₄ and sequencer start address assigned to STAD writing area 21 identical sequencer start address STA
D ( "address 2000") have been written, which in sequencer mode, the sequencer write SW8 remain turned on "F ^# _4", the two keys of "G _4" simultaneously depressed Corresponds to the operation. Thus, the sequencer
In the mode, when a plurality of keys are pressed while the sequencer writing SW8 is turned on, the sequence data writing start address of the sequence data writing area 22 corresponding to those keys is set to the same address.

Returning to the flow chart of FIG. 5A, the description will be continued.
When determining that the flag is not “1” but “0”, the CPU 12 subsequently determines whether or not the sequencer mode flag is “1” (S23). As a result of the determination, if the sequencer mode flag is not “1” but “0”, that is, if the performance mode is the normal mode, the pitch corresponding to the newly operated key is operated. After performing a normal key ON process for controlling the tone generator circuit 16 so as to generate a musical tone (S24), the process returns to the main routine (RET).

By the above operation, when a key press operation of an arbitrary key of the keyboard 2 is performed while the performance mode is the normal mode, a musical tone having a pitch corresponding to the pressed key is generated. Processing is performed.

On the other hand, if the sequencer mode flag is determined to be "1" in step S23, that is, if the performance mode is the sequencer mode, then it is determined whether the sequencer write standby mode flag is "1". (S2
Five). If the sequencer write standby mode flag is “0” instead of “1”, the CPU 12 starts the sequencer start corresponding to the key for which a new key press operation has been performed detected in the above-described process S19. It is determined whether or not the storage area 21a in the address STAD write area 21 stores the sequencer start address STAD which is the sequence data write start address in the sequence data write area 22 (S26).

If the sequencer start address STAD is not stored, the normal key ON process is performed, and the process returns to the main routine.

On the other hand, if the sequencer start address STAD is stored in the process S26, the automatic performance is performed based on the sequence data stored in the sequence data write area 22, as described in detail later. After performing the sequencer regeneration process to be performed (S27), the process returns to the main routine (RET).

By the above operation, when any key of the keyboard 2 is pressed first in the sequencer playback mode, the sequencer is started based on the sequencer start address STAD written in the sequencer start address STAD write area 21 of the RAM 15. The sequence data for automatic performance is read from the area of the data writing area 22, and the automatic performance is performed based on the read sequence data.

On the other hand, in the process S25, the sequencer write standby mode
If the flag is “1”, the CPU 12 sets the sequencer recording flag to “1” (S2).
8), the sequencer write standby mode flag is reset to "0" (S29), and the display state of the LED 10 is changed from a blinking state to a lighting state (S30).

Subsequently, the CPU 12 sets the sequencer start address STAD written in the process S22 in the ADD register (S31), and stores the pitch data relating to the key pressing operation at the address indicated by the set ADD register. (S32).
Then, the CPU 12 increments the content of the ADD register by "1" (S33), and generates a musical tone having a pitch indicated by the pitch data stored in the processing S32 at the address indicated by the incremented ADD register. The designated key ON data is stored (S34). Then, when the above processing is completed, C
The PU 12 starts the sequencer timer 20 to start measuring the time until the next sequencer writing process starts (S35), and then returns to the main routine (RE35).
T).

By the above operation, when the first key is pressed in the sequencer write standby mode, the performance mode switches from the sequencer write standby mode to the sequencer recording mode, and the LED 10 blinks to indicate that the mode has switched to the sequencer recording mode. Changes from to lighting. In addition, pitch data and key ON data for instructing generation of a musical tone having a pitch of a key depressed first are continuously written from the write start address STAD of the sequence data write area 22. In addition, the timing of the sequencer timer 20 is also started in order to measure the key-pressing time of the pressed key.

On the other hand, in the process 19, when there is no newly pressed key, the CPU 12 next, based on the previous key pressing information and the current key pressing information stored in the RAM 15, It is determined whether or not there is a newly released key (S36). If there is no new key release, it is determined that there is no change in the key depression operation of the key on the keyboard 2, and the process returns to the main routine. Return (RE
T).

On the other hand, if there is a new key release in the process S36, the CPU 12 determines that the sequence data written in the sequence data write area 22 corresponding to the released key is currently being reproduced. It is determined whether or not there is (S3
7) If the reproduction based on the sequence data is not being performed at present, the tone generator circuit 16 is stopped so as to stop the generation of the musical tone having the pitch corresponding to the released key detected in the above-described process S36. After performing the normal key OFF process for control (S
38), return immediately to the main routine (RET).

According to the above operation, when a new key is released in the normal mode, generation of a musical tone having a pitch corresponding to the released key is stopped.

On the other hand, if it is determined in step S37 that the sequence data corresponding to the released key is being reproduced, the CPU 12
Determines whether the continuation flag is "1" (S39), and if the continuation flag is "1", determines that the reproduction of the sequencer is to be continued and immediately returns to the main routine. Returning (RET), if the continuation flag is “0” instead of “1”, it is determined that the reproduction of the sequence data is not to be continued, and the key corresponding to the newly released key is determined. sequence·
After performing control to stop data reproduction (S40), the process returns to the main routine (RET).

As described later, the continuation flag is set to “1” by operating the pedal SW5 from “off” to “on” in the sequencer playback mode.

Therefore, according to the above operation, when the reproduction of the sequence data corresponding to the depressed key is started by pressing a key in the sequencer reproduction mode, the pedal SW5 is released before the key is released. If the foot switch is turned on by operating the foot, sequence data playback will continue, but if the pedal SW5 is not turned on by foot operation before the key is released, the release of the key will occur. The reproduction of the sequence data is immediately stopped by the key. In addition,
Pedal SW related to continuation and stop of this sequence data
The processing for the foot operation 5 will be described in detail in the pedal SW scanning processing described later.

On the other hand, in the process S18, the sequencer recording flag is set to "1", that is, the sequencer recording mode is set, and the sequence / data write area 22 of the RAM 15 is set.
If the writing of various sequence data has already been started, the CPU 12 next calculates the keypress information based on the previous keypress information and the current keypress information stored in the RAM 15.
It is determined whether there is a newly released key (S41).
If there is a newly released key, the CPU 12
Indicates the key-off data of the musical tone at the pitch corresponding to the newly released key in the sequence data write area of the RAM 15.
A process of writing to the corresponding address of 22 is performed.

That is, the CPU 12 first increments the content of the ADD register by "1" (S42), and sets timer data indicating that the data indicates the note length of the sequence data at the address indicated by the ADD register (S43). ). Then, the CPU 12 further increments the content of the ADD register by “1” (S44), and indicates the timer time read from the sequence timer 20 at the address indicated by the ADD register, that is, the note length of the released key. Set the data (S45). When the setting of the note length is completed, the CPU 12 resets the sequencer timer 20, and then starts time measurement again (S46).

Next, the CPU 12 increments the content of the ADD register by "1" (S47), and sets pitch data corresponding to the released key detected in the process S41 (S48). Further, the CPU 12 further increments the content of the ADD register by “1” (S49), and stores the key in the address indicated by the ADD register.
After setting OFF data (S50), the process immediately returns to the main routine (RET).

By the above operation, when the pressed key is released in the sequencer write mode, the key corresponding to the pressed key written from the corresponding address of the sequence data write area 22 of the RAM 15 in the above-mentioned processes S31 to S35. Following the pitch data and its key ON data, the timer data, timer time data (note length data), the pitch data corresponding to the released key equal to the depressed key, and its key OFF data are sequentially displayed. Written.

On the other hand, in the process 41, when there is no newly released key, the CPU 12 stores the current key press information stored in the RAM 15 in the process S17 and the previous key press information stored in the RAM 15 in the previous interrupt process S17. Based on the key pressing information, it is determined whether or not there is a newly pressed key (S51). Then, when there is a newly pressed key, a process of writing key ON data for instructing generation of a musical tone having a pitch corresponding to the newly pressed key into the sequence data writing area 22 of the RAM 15 is performed. Do.

That is, first, the CPU 12 increments the content of the ADD register by "1" (S52), and sets timer data, which is sequence data, to the address indicated by the ADD register (S53). Then, the CPU 12 further increments the content of the ADD register by “1” (S54), and reads the timer time read from the sequence timer 20 to the address indicated by the ADD register, that is, from the key release of any previously detected key. Data indicating a time (corresponding to a rest length) until a predetermined key detected this time is pressed is set (S55). When the setting of the timer time is completed, the CPU 12
The timer 20 for the sequencer is reset and time measurement is started again (S56).

Next, the CPU 12 increments the content of the ADD register by "1" (S57), and then sets the pitch data corresponding to the depressed key detected in the processing S51 (S58). Then, the CPU 12 further increments the content of the ADD register by "1" (S59), sets key ON data for instructing the start of generation of a musical tone at the address indicated by the ADD register (S60), and then proceeds to the main routine. Return immediately (RET).

By the above operation, the sequence data writing area 22 of the RAM 15 stores the timer data, the timer time (note length), the pitch data corresponding to the most recently released key, Subsequent to the key OFF data, timer data, a timer time corresponding to the rest length, pitch data corresponding to a newly depressed key, and its key ON data are sequentially written.

On the other hand, in the process S51, when there is no new key press, the CPU 12 next determines whether or not any of the switches of the timbre / effect switch SW group 6 is in the ON state. (S61). If at least one switch of the tone / effect switch group 6 is in the ON state, data on the tone and effect of the tone corresponding to the tone / effect switch in the ON state is stored in the sequence Write to the data write area 22.

That is, the CPU 12 first increments the content of the ADD register by "1" (S62), and adds it to the address indicated by the incremented ADD register to the tone corresponding to the ON-state tone / effect switch. An effect (tone color) data indicating an effect (or tone color of a musical tone) (for example, data indicating the effect when vibrato is added to a musical tone, or tone data indicating a tone color in the case of a musical tone) is set ( S63). Then, the CPU 12 further increments the content of the ADD register by “1” (S64),
Effect value (tone value) indicating the value of the effect to be added to the tone (or the value indicating the tone color of the tone) at the address indicated by the ADD register
After setting (for example, a delay time when an echo is added to a musical tone) (S65), the process returns to the main routine (RET).

When the timbre or the effect is switched by operating any one of the switches of the timbre / effect switch SW group 6 by the above operation, the tone is added to the corresponding address of the sequence data writing area 22 of the RAM 15. The effect data or tone color data indicating the effect or tone color of the tone to be set is set, and the effect value or the tone value indicating the tone color of the tone to be added to the tone is set following the data.

On the other hand, if it is determined in the processing S61 that all the switches of the tone / effect switching SW group 6 are OFF, the CPU 12
Determines whether the sequencer recording flag is "1" (S66), and if it is "1", returns to the main routine immediately (RET).

By the above operation, when the sequencer recording mode is continued, subsequently, a key press / key release operation on the keyboard 2 or an operation on each switch of the tone / effect switching SW group 6 is performed.
The process of writing the sequence data continues.

On the other hand, if the sequencer recording in progress flag is "0" in the process S66, the content of the ADD register is incremented by "1" (S67), and then the end of the music relating to the automatic performance is added to the address indicated by the ADD register. After setting the END data indicating (S68), return to the main routine (RE
T).

By the above operation, when the sequencer write SW8 is turned ON in the sequencer recording mode, END is added to the end of the sequence data written in the sequence data write area 22 of the RAM 15 in the sequencer recording mode.
The data is written, and the writing of the automatic performance information ends.

Here, the sequencer SW writing process described above will be described with reference to an example of various types of automatic performance information actually written in the sequence data writing area 22 of the RAM 15.

FIG. 7 shows the sequence / data write area 2 of the RAM 15
FIG. 3 is a diagram showing various sequence data written to 2.

First, consider a case where a player plays a musical piece described in FIG. 2A in the sequencer mode.
In this case, as shown in FIG. 3B, the pitch data (C ₄ ) corresponding to the note (1) and the pitch data ( Key ON data for instructing the generation of C ₄ ), timer data, note length (quarter note length), pitch data (C ₄ ),
Key-off data for instructing stop of generation of the tone data of the pitch data is sequentially written. That is, these processes correspond to the processes S31 to S35 and the processes S41 to S50 in FIG.

At this time, the timbre / effect switching SW group 6 is set to the time from the key release operation for the note (1) to the key press operation for the note (2).
Is operated by the player, effect data or tone color data and effect value data or tone color value data are sequentially written following the written automatic performance information. This process corresponds to the processes 61 to 65 shown in FIG.

First, the time interval from the key release operation for the note (1) to the key press operation for the note (2) is written by timer data and timer time data. Hereinafter, the sound corresponding to the note (2) will be described. high data (D _4), the key ON data indicating the occurrence of the sound pitch data (D _4), the timer data, note length (8-note length), pitch data (D _4), of the sound height data Key OFF data is written sequentially. The sequencer writing process corresponds to the processes S51 to S60 in FIG. Then, hereinafter, the processing S66 to S66 shown in FIG.
Until the END data is written at 68, various sequence data are written one after another in accordance with the key press / key release operation of the keyboard 2 and the operation of the tone / pitch switch SW group 6.

Sequencer Playback Process The sequencer playback process S27 is a process of sequentially playing back various types of automatic performance information written in the sequence data write area 22 of the RAM 15.

FIGS. 8A to 8C are flow charts for explaining the sequencer reproduction process S27 performed by the CPU 12. FIG.

As shown in the figure, first, the CPU 12 reads the sequencer start address STAD corresponding to the depressed key from the sequencer start address write area 21, and sets it in the ADD register (S69).

That is, if explained with the embodiment shown in FIG. 6, for example, F ^# ₄ of keys, when it is depressed in the sequencer mode, the sequencer start address STAD assigned to the key of the F ^# ₄ "2000" from the PLC start address write area 21 and ADD
Set in a register.

Next, the CPU 12 determines the address indicated by the ADD register ("2000
Address) is set in the A register (not shown) in the CPU 12 (S70), and the content of the ADD register is set to "1".
After incrementing ("2001") (S71), ADD
The contents of the address indicated by the register ("2001") are set in a B register (not shown) (S72).

Next, the CPU 12 determines whether or not the content set in the A register is pitch data (S73). And A
If the content set in the register is pitch data, CP
Next, U12 determines whether or not the content of the B register is key ON data (S74). If the content set in the B register is the key ON data, the CPU 12 supplies the pitch data set in the A register to the tone generator circuit 16 and generates a tone having a pitch corresponding to the pitch data. Sound processing for controlling the tone generator circuit 16 so as to be performed (S75),
The process returns to the processing S70 again.

According to the above operation, when the sequence data set in the A register is the pitch data and the sequence data set in the B register is the key ON data, the tone data of the pitch indicated by the pitch data is generated. A pronunciation process is performed.

For example, if the sequence data is stored as shown in FIG. 7, the pitch data (C ₄ ) at address 2000 is set in the A register, the key ON data at address 2001 is set in the B register, and “C ₄ Is supplied to the tone generator circuit 16,
Pitch of the musical tone corresponding to the tone pitch data of "C _4" is generated,
D / A converter 17, amplifier 18 of tone generator 19, speaker 11
The musical tone having the pitch of “C ₄ ” is emitted to the outside.

On the other hand, if the content set in the B register is not the key-on data but the key-off data in the process S74, the CPU 12 executes a silencing process for stopping the generation of the musical tone currently being generated by the tone generator 16. After going (S76) ADD
The register is incremented (S76-1), and the process S70 is performed.
Return to

After returning to the process S70, the CPU 12 returns to the process S70
To the process S72, and in the process S73, it is determined whether or not the content set in the A register is pitch data. If sequence data other than pitch data is set in the A register, the next processing
Move to S77.

In this process S77, the CPU 12 determines whether or not the content set in the A register is effect data (or tone color data) indicating an effect to be added to the musical tone (S77).
If the content set in the A register is the effect data, the CPU 12 supplies the effect value (or tone color value) set in the B register to the tone generator 16, and After performing control to add a predetermined effect to the current tone (or control to set the tone of the tone) (S7
8), the process returns to the processing S76-1 again.

By the above operation, the sequence data set in the A register is the effect data indicating the effect to be added to the tone, and the sequence data set in the B register is the effect value indicating the value of the effect to be added to the tone. In some cases, the effect indicated by the effect data and the effect value is added to the musical sound with the strength (depth) corresponding to the effect value (parameter). That is, according to the example shown in FIG. 7, the effect data at the address 2006 is set in the A register.
When the effect value at the address 2007 is set in the B register, the effect value is supplied to the tone generator circuit 16 and a tone to which the effect indicated by the above effect data is added at the intensity (depth) corresponding to the effect value is generated. Then, the musical sound is emitted to the outside via the D / A converter 17 and the musical sound generator 19.

On the other hand, if the effect data is not set in the A register in the process S77, the CPU 12 next determines whether or not the content set in the A register is timer data (S79). If the data is data, the timer time set in the B register is set in the sequencer timer 20, and the sequencer timer 20 is controlled so as to subtract the set timer time (S80).

Then, the CPU 12 determines whether the timer time has reached “0” until the timer time reaches “0” (step S8).
1 is repeated (wait), and when the timer time reaches “0”, the flow returns to the process S76-1 again.

According to the above operation, if the sequence data set in the A register is timer data and the sequence data set in the B register is timer time such as a note length, the timer data and the timer time are used. The tone generation time of a musical tone and the time from the silence of one musical tone to the tone generation of the next musical tone are controlled based on the tone.

That is, in the example shown in FIG. 7, if the timer data of address 2002 is set in the A register and the note length of address 2003 is set in the B register, the tone generator circuit is set.
The tone generation time of the tone generated from step 16 is controlled to be equal to the timer time. If the timer data at address 2008 is set in the A register and the timer time at address 2009 is set in the B register, the musical tone at the pitch “C ₄ ” is muted before the pitch at “D ₄ ” The time until the musical sound is generated is controlled so as to be equal to the timer time.

On the other hand, if it is determined in step S79 that the content set in the A register is not timer data, the CPU 12 then determines whether the content set in the A register is E data.
It is determined whether or not the data is ND data (S82). And A
If the content set in the register is not END data, the process immediately returns to the main routine (RET). If the content is END data, stop control for stopping the sequencer reproduction process is performed (S83).・ Return to the routine (RET).

With the above operation, if the sequence data set in the A register is END data, the sequencer reproduction processing ends.

Note that the CPU 12 independently executes the sequencer reproduction process for each channel by time division control. Therefore, in the sequencer mode, a different sequencer address is stored in the sequencer start address STAD write area 21.
If multiple keys with the start address STAD set are pressed at different timings, the playback of the automatic performance information stored in the sequence data writing area 22 corresponding to each key is independent for each key. It is possible to do.

Therefore, in the sequencer recording mode, it is possible to write the same automatic performance information corresponding to two different keys of the keyboard 2 and reproduce the automatic performance information at a different time, that is, a so-called ringing performance.

FIG. 9 shows two different keys of the keyboard 2 ("F ^# ₄ " and "G
₄ ] is a diagram showing an example of a case where the same automatic performance information written in the sequence / data writing area 22 corresponding to ( ₄ )) is reproduced at a shifted timing to perform a ringing performance.

In this case, it is assumed that, in the sequencer recording mode, the R assigned to the “F ^# ₄ ” and “G ₄ ” keys of the keyboard 2.
It is necessary that the same sequencer start address STAD ("2000" in the example shown in FIG. 6) is written in each storage area 21a of the sequencer start address STAD write area 21 of AM15. That is, in the sequencer recording mode, after simultaneously depressed key and the key of "G _4" in while the sequencer write SW8 ON state "F ^# _4", by the sequencer write SW8 in an OFF state,
Corresponding to the key of "F ^# _4" key and "G _4" in, it is assumed that the same automatic performance information is written in the same storage area of the sequence data write area 22.

In this case, in the sequencer playback mode, first, when the player depresses the key of “F ^# ₄ ” on the keyboard 2,
At the timing of the key depression, as shown in the upper part of FIG.
The CPU 12 starts the reproduction of the automatic performance information relating to the predetermined music written in the sequence data write area of the RAM 15 after the address 2000. Subsequently, when a predetermined music piece during the playback is depressed operates the key of "G _4" in the keyboard 2 when approaching the beginning of the second bar continues to perform its key depression operation thereafter, the ninth As shown in the lower part of the figure, in the same manner as in the case of the key pressing operation of the key of "F ^# ₄ ", the automatic performance related to the predetermined music written in the sequence data write area of the RAM 15 after the address 2000 is performed. The reproduction of the information is started by the CPU 12 at the key depression timing of the key of "F ^# ₄ ".

Thus, in the sequencer recording mode, the keyboard 2
By writing the same automatic performance information corresponding to a plurality of keys in the sequencer mode, if the same automatic performance information written corresponding to each of the keys is reproduced at a different time in the sequencer mode, the player Can enjoy singing by automatic performance.

Note that the automatic performance in the sequencer mode is continued until the end point of the musical composition while the key pressing operation is continuously performed, and is stopped immediately when the key is released.

Pedal SW Scan Processing In the pedal SW scan processing, the state of the pedal SW5 and the pedal mode switch SW9 is periodically detected by an interrupt processing performed by the CPU 12 at a predetermined cycle, and the sequencer being reproduced according to the pedal mode of the electronic keyboard instrument is executed. This is a process for controlling the continuation and stop of the key without depending on the continuation of the key pressing operation of an arbitrary key on the keyboard 2.

FIG. 10 is a flow chart for explaining the pedal SW scan processing performed by the CPU 12.

In this pedal SW scan processing, the CPU 12
Is the pedal switch ON that indicates that the pedal SW5 is in the ON state.
The flag ("1" when in the ON state) is used.

As shown in FIG.
Is started by detecting the status of the pedal SW5 (the damper pedal SW5a and the soft pedal SW5b) (S84).

Here, when the pedal SW5 is not in the ON state but in the OFF state, the CPU 12 next sets the pedal SW / ON flag to “1”.
Is determined (S85). If the pedal SW / ON flag is "0" instead of "1", the routine immediately returns to the main routine (RET).

On the other hand, in step S84, the pedal SW / ON flag is set to “1”.
Is satisfied, the pedal SW / ON flag is reset to "0" (S86), and the process returns to the main routine (RE
T).

When the pedal SW5 changes from “ON” to “OFF” by the above operation, the pedal SW / ON flag is changed from “1” to “0”.
, Or when the pedal SW5 is continuously “OFF”, the pedal SW / ON flag remains set to “0”.

On the other hand, if the pedal SW5 is in the ON state in the process S84, the CPU 12 determines whether or not the pedal SW / ON flag is “1” (S87), and sets the pedal SW / ON flag to “1”. ", Return to the main routine (RET),
If the pedal SW / ON flag is "0", the pedal SW / ON flag is set to "1" (S88).

With the above operation, when the pedal SW5 changes from “OFF” to “ON” as in the case where the pedal SW5 is first operated by the foot, the pedal SW / ON flag is set from “0” to “1”. .

After setting the pedal SW / ON flag to “1” in the above process S88, the CPU 12 detects the status of the pedal mode switching SW9 and determines whether or not the pedal mode is set to the sequencer / pedal mode. It is determined (S89). When the pedal mode is set to the normal pedal mode, the CPU 12 sets the damper pedal SW5a.
Alternatively, according to the status of the soft pedal SW5b, after performing a normal pedal ON process for controlling the tone generator 16 so that a damper effect or a soft effect is added to the musical tone generated from the tone generator 16 (S90). ), Return to the main routine (RET).

On the other hand, if the sequencer pedal mode has been set in the processing S89, the CPU 12 refers to the sequencer reproduction flag and determines whether or not the sequence data is currently being reproduced (S91). ).

Then, when the sequence data is not being reproduced, the CPU 12 performs the normal pedal ON process S90,
The process returns to the main routine. If the sequence data is being reproduced, it is determined whether the continue flag is "1" (S92).

If the result of this determination is that the continue flag is "0", the CPU 12 sets the continue flag to "1" (S93) and returns to the main routine (RET). When the flag is “1”, after controlling the tone generator circuit 16 to perform the stop control of the sequencer and the processing of resetting various sequencer flags (pedal SW / ON flag, continuation flag) to “0”, (S94), and returns to the main routine.

By the above operation, when the pedal SW5 is first turned on in the sequencer playback mode and the sequencer pedal mode, the continuation flag is set to “1”, and the key press for designating the automatic performance is performed as described above. Even if the operation is stopped, the reproduction of the sequence data is continued (see steps S86 to S89 in FIG. 5B). In this sequencer playback mode and sequencer pedal mode, if the pedal SW5 is turned on again, the playback of sequence data (automatic performance) is immediately stopped.

Second Embodiment Next, an electronic keyboard instrument according to a second embodiment will be described.

Configuration The external appearance and the configuration of the internal circuit of the electronic keyboard instrument of the second embodiment are the same as those of the electronic keyboard instrument of the first embodiment. Only the configuration of the storage area of the RAM 15 is the feature of this embodiment. Is slightly different in order to execute a process of repeatedly using the automatic performance data. Therefore, as for the configuration of the second embodiment, the description of FIGS. 1 and 2 used in the first embodiment is omitted as it is, and the description thereof is omitted. Only the configuration will be described.

FIG. 11 is a diagram showing a configuration of a storage area of the RAM 15 in the second embodiment.

As shown in the figure, the storage area of the RAM 15 includes a sequencer start address STAD write area 31 starting at address 1000, a sequence data write area 32 starting at address 2000, and an address 5000 which is a feature of the second embodiment. And is divided into three areas of a repeated performance data writing area 33 starting from.

Do. Hereinafter, a description will be given mainly of a pitch writing process of a musical piece related to an automatic performance different from that of the first embodiment. The same reference numerals are given to the same processes as those in FIGS. 5 (a) to 5 (e).

FIGS. 12A to 12E are flow charts for explaining the sequencer writing process in the second embodiment.

As shown in the figure, each processing from processing S17 to processing S25 is the same as each processing shown in the first embodiment. Then, CPU 12 may pitch sequencer write standby mode flag corresponding to a new key depression in the processing S19. If not "1" in the processing S25 is to determine whether a C ₃ or less (S95 ). Then, the tone pitch C ₃ or less (C ₁ -C

The sequencer start assigned to each key
In the storage area 31a of the address STAD write area 31, "2000" and "3000" which are write start addresses of the sequence data corresponding to the respective keys in the sequence data write area 32 are written. Also,
In the figure, the storage area 31 of the sequencer start address STAD write area 31 assigned to the key of “F ^# ₂ ”
`` 5000 address '' is written for a, which is the automatic performance information written in the sequencer start address STAD writing area 32 corresponding to the key of `` F ^# ₂ '' in the sequencer recording mode. The first pitch to be pronounced is equal to the last pitch to be pronounced, and the automatic performance information is transferred to the repeated performance data writing area 33 starting at address 5000 and rewritten, and in the sequencer mode, `` C ^# ₃ This is because the key is repeatedly used in response to the depression of a key having a pitch equal to or higher than the pitch.

In step S19, when there is no new key press, the processing from step S36 to step S36 described in the first embodiment is repeated.
Since the processing is the same as the processing up to 40, the description is omitted.

On the other hand, in the process S18, when the sequencer recording in progress flag is “1”, that is, the sequencer recording mode is set, and the writing of the sequence data to the sequence data writing area 32 of the RAM 15 has already been started. The CPU 12 executes the process S41 described in the first embodiment.
After executing steps S47 to S47, the pitch difference data stored in the C register is set at the address indicated by the ADD register (S99). The processing of steps S49 and S50 shown in the first embodiment will be described below. Run.

By the above operation, the sequence data write area 32 of the RAM 15 stores the sound of "0" corresponding to the musical tone first generated in the sequencer reproduction mode corresponding to the key pressed first in the sequencer write standby mode. Subsequent to the pitch difference data, pitch difference data relating to a key release indicating a pitch difference between a pitch of a musical tone corresponding to a key depressed after the second key and the above-mentioned first pitch is sequentially written. It is.

On the other hand, if there is no new key release in the process 41, the CPU 12 executes the processes S51 to S57 described in the first embodiment, and then stores the keyboard in the C register in the sequencer recording mode. Pitch difference data which is a value obtained by subtracting the pitch data indicating the pitch of the musical tone first generated in the sequencer playback mode set in the A register from the pitch data indicating the pitch specified by the key press of No. 2 (S100), and set C at the address indicated by the ADD register.
Set the pitch difference data that is the contents of the register (S10

Execute the process of S60.

By the above operation, the pitch data of the musical tone corresponding to the key pressed first in the sequencer writing standby mode and the sequence key recording mode in the sequencer recording mode are stored in the sequence data writing area 32 of the RAM 15. The pitch difference data relating to the key depression indicating the pitch difference from the pitch of the musical tone corresponding to the key depressed is sequentially written.

If there is no new key press in step S51, the process is the same as steps S61 to S68 described in the first embodiment, and a description thereof will not be repeated.

By the above-described sequencer writing processing, pitch difference data relating to the pitch of the musical tone in the automatic performance information is stored in the sequence / data writing area 32 of the RAM 15 in accordance with the key press / release in the sequencer recording mode. Written with the sequence data.

In the sequencer recording mode, if the pitch data of the first tone generated in the automatic performance information written in the sequence data writing area 33 is equal to the pitch data of the last tone generated, the sequencer playback is performed. In the mode, when a key having a pitch of "C ^# ₃ " or more is depressed, the automatic performance information is written to the repeated performance data writing area 33 of the RAM 15 in order to repeatedly use the automatic performance information. (Moved).

In the following, a process performed by the CPU 12 for detecting repetitive performance information and writing the repetitive performance information to the repetitive performance data writing area 33 of the RAM 15 will be described.

FIG. 14 is a flow chart for explaining repetitive performance data extraction processing of the sequencer SW scanning processing in the second embodiment.

As shown in the figure, in the sequencer / SW scan process of the second embodiment, after performing the turning off process S16 of the LED 10,
Repeated performance data extraction processing S102 to S103 are performed.

First, in the sequencer write mode, the CPU 12
It is determined whether or not the pitch difference data set in the register is "0" (S102). If the pitch difference data set in the C register is not "0", the process immediately returns to the main routine (RET). If it is "0", the sequence data write area 32 of the RAM 15 is read. The sequence data written to the address after the sequencer start address STAD is repeatedly moved to the start address (5000) or later of the performance data writing area 33 except for the END data (S103).

According to the above operation, in the sequencer recording mode, when the first pitch and the last pitch of the automatic performance information input by the player are equal, the CPU 12 stores the automatic performance information in the sequencer playback mode as `` C ^The sequence data once written in the sequence data writing area 32 is repeatedly moved to the performance data writing area 33 so as to be repeatedly used for the reproduction of the automatic performance information corresponding to the depression of the key having the pitch of ^# ₃ or more. Then, in the sequencer playback mode described later, if the pressed key of the keyboard 2 has a pitch equal to or higher than "C ^# ₃ ", the playback of the automatic performance information starts from the pitch of the pressed key. Thus, the automatic performance information stored in the repeated performance data writing area 33 is reproduced while shifting the pitch.

Sequencer Reproduction Processing This sequencer reproduction processing is the same as that of the eighth embodiment in the first embodiment.
This is almost the same as the sequencer reproduction process shown in FIGS. 7A to 7C, but a process different from that of the sequencer reproduction process of the first embodiment is performed with respect to the pitch reproduction process of the music piece related to the automatic performance. Hereinafter, a description will be given focusing on the reproduction processing of the pitch of a musical piece related to the automatic performance different from that of the first embodiment. Note that the same reference numerals are given to the same processes as those in FIGS. 8 (a) to 8 (c).

FIGS. 15A to 15C are flow charts for explaining the sequencer reproduction processing in the second embodiment.

As shown in the figure, first, the CPU 12 determines whether or not a key corresponding to a new key press in the sequencer writing process is “C ₃ ” or less (S104). As a result of the determination, if the pitch corresponding to the new key depression is equal to or less than “C ₃ ”, the sequencer start
Set the address STAD the ADD register (S69), the pitch is higher than the "C _3" sets the block number 5000 in ADD register (S105).

According to the above operation, in the sequencer write mode, when writing a sequence data to the sequence data write area 32 of the RAM 15 and pressing a key corresponding to a pitch equal to or lower than "C ₃ ", the first embodiment is executed. By the same processing as described above, the start address of the storage area in the sequence / data write area 32 is set in the ADD register.
_When a key corresponding to a pitch higher than ₃ "is pressed, the RAM
Area 15 for writing repeated performance data after address 5000 in 33
In order to play back a music piece based on the sequence data (repeated performance data) moved to, the address 5,000 is set in the ADD register.

Next, the CPU 12 executes each processing from the processing S70 to the processing S73 in the same manner as in the first embodiment, and then determines whether or not the content set in the A register in the processing S73 is the pitch difference data. Is determined. If the content of the A register is pitch difference data as a result of the determination, the content of the A register is added to the content of the process S19 in the flow chart of FIG.
The result obtained by adding the pitch data corresponding to the depressed key detected in step A is set in the A register (S106), and it is determined whether the contents of the B register are key ON data (S74). ). If it is key-on data, the new pitch data set in the A register is supplied to the tone generator circuit 16 so that the tone of the pitch corresponding to the new pitch data is generated. A sound generation process for controlling the circuit 16 is performed (S107), and the process returns to the process S76-1 again.

On the other hand, if the content set in the B register is the key-off data in the process S74, the CPU 12 performs a silencing process for stopping the generation of the musical tone currently being generated from the tone generator 16 (S76). ), And returns to the process S76-1 again.

According to the above operation, when the sequence data set in the A register is pitch difference data and the sequence data set in the B register is key ON data, the pitch difference data and the sequencer mode are used. The sound generation process is performed based on the pitch corresponding to the key that is pressed first.

If the content set in the A register is not the pitch difference data in the processing S73, the processing from the processing S77 to the processing S83 described in the first embodiment is performed.

Here, in the above-described sequencer reproduction processing, the RAM 15

On the other hand, in the sequencer mode, FIG.
As shown in (c), when a key such as “F ₄ ” or “D ₄ ” of the keyboard 2 which is higher than “C ₃ ” is pressed, the key is repeatedly corresponding to the key of “F ^# ₂ ”. It said automatic performance information stored in the performance data write area 33, pitch as starting from the pitch, such as "F _E" and the "D _4" is reproduced is changed. That is, as shown in Figure 16 (a), in the case where the "F ^# _2" automatic performance information stored in correspondence with the key begins pitch of a tone of the "C _4", of the keyboard 2 ' when the key of F ₄ "is key depression is a pitch difference between the" to be played to the music from the pitch of F ₄ ", generally comprises a" C ₄ "," F ₄ "5 The pitch of the degree is raised and played. Similarly, in the sequencer mode, when the key “D ₄ ” of the keyboard 2 is pressed, the music is reproduced from the pitch “D ₄ ” as a whole, so that the music is reproduced from the pitch “D ₄ ”. the pitch of 2 degrees at pitch differences between the "D _4" is reproduced as high as.

As described above, if the repetitive performance data stored in the repetitive performance data writing area 33 is controlled so as to be reproduced while changing the pitch, the automatic performance allows
For example, an auto arpeggio, an auto chord, an auto bass, an auto trill, etc. can be enjoyed. Note that the repetitive performance of a predetermined music piece by the above-described sequencer playback processing is continued as long as the first key pressed in the sequencer mode is continuously pressed, and is stopped by releasing the above key. I do.

Pedal SW Scan Processing This pedal SW scan processing is the same as the first embodiment.
Similar to the pedal SW scan processing shown in FIG. 10, the CPU 12 periodically detects the states of the pedal SW5 and the pedal mode switch SW9 by an interrupt processing performed at a predetermined cycle, and reproduces the state according to the pedal mode of the electronic keyboard instrument. This is a process for controlling the continuation and stop of the middle sequencer without depending on the continuation of the key press operation of the key of the keyboard 2. Therefore, in this section, illustration and description of the pedal SW scan processing are omitted.
