[0011]

According to the present invention, the musical sound of each part in the automatic performance device is reproduced in accordance with the automatic performance data stored in the storage means, while the tone generation instructing means such as a keyboard also has the same performance data as the automatic performance data. Since the automatic performance data and the performance data generated in response to the instruction of the sound generation instructing means are appropriately used to reproduce the musical sound of the specific part, the operation load on the player is reduced. .

That is, in the invention described in claim 1,
In an automatic performance device of an electronic musical instrument that generates an automatic performance sound in synchronization with the tempo, a part other than a specific part selected from among a plurality of parts is stored in advance in the storage means when a pronunciation instruction is given by the pronunciation instruction means. The stored automatic performance data is used to pronounce a specific part.

Thus, for example, a musical tone according to the pitch data in the automatic performance data stored in the storage means is sounded at the timing instructed by the sounding instructing means. In this case, if the player gives only the sounding timing by the sounding instructing means without paying attention to the pitch, the musical sound of the specific part corresponding to the sounding timing is reproduced. That is, when, for example, a keyboard is used as the sounding instructing means, when a player presses any key, a specific part with a pitch according to the pitch data (original pitch) in the automatic performance data in response to the key being pressed. Since the musical tone is generated, even a beginner can enjoy the automatic performance as if he / she is playing the particular part, simply by pressing any key.

According to a second aspect of the invention, in the automatic musical instrument of the electronic musical instrument, the parts other than the specific part selected from the plurality of parts generate automatic musical sounds in synchronization with the tempo. When a sounding instruction is given, a specific part is sounded according to the data that determines the pitch, note length and velocity of the automatic performance data stored in advance in the storage means. In other words, the sounding timing is specified by the sounding instructing means, and the pitch, note length and velocity are specified by the automatic performance data to generate a specific part of the musical sound.

As a result, at the timing instructed by the sounding instructing means, a musical tone according to the pitch, note length and velocity data in the automatic performance data stored in the storage means is sounded. Therefore, for example, when a keyboard is used as the pronunciation instruction means, the performer simply gives the timing of starting the pronunciation on the keyboard without worrying about the key to be pressed, the key pressing time, and the strength of the key pressing. Since the original musical sound of the particular part (a musical sound having a pitch, note length and velocity according to the automatic performance data) is generated simply by performing the above-mentioned operation, the player feels as if he or she is playing the particular part. You can enjoy the automatic performance with a sense.

According to the third aspect of the invention, the parts other than the specific part selected from the plurality of parts generate the automatic performance sound in synchronization with the tempo. When there is a pronunciation instruction, the velocity indicated by the pronunciation instruction means,
A particular part is sounded according to the automatic performance data stored in advance in the storage means and the data for determining the pitch and the note length. In other words, the tone generation timing and velocity are designated by the tone generation instructing means, and the pitch and the note length are designated by the automatic performance data so as to generate the musical tone of the specific part.

Thus, at the timing instructed by the sounding instructing means, a musical tone is generated in accordance with the velocity instructed by the sounding instructing means and the pitch and note length data in the automatic performance data stored in the storage means. To be done. Therefore,
For example, when a keyboard is used as the sounding instructing means, the performer performs a simple operation of giving the sounding start timing and the strength of key pressing on the keyboard without worrying about the key to be pressed and the key pressing time. Only then, the musical sound of the particular part is generated, so that the player can enjoy the automatic performance as if playing the particular part. In this case, since the strength of the sound is determined according to the key depression, it is possible to perform the automatic performance in which not only the sounding timing but also the strength of the sound reflects the player's will.

According to a fourth aspect of the invention, in the automatic musical instrument of the electronic musical instrument, the parts other than the specific part selected from the plurality of parts generate automatic musical sounds in synchronization with the tempo, by the sounding instructing means. When a sounding instruction is given, a particular part is sounded according to the note length designated by the sounding designating means and the data for determining the pitch and velocity of the automatic performance data stored in advance in the storage means. In other words, the tone generation timing and the note length are designated by the tone generation instructing means, and the pitch and velocity are designated by the automatic performance data so as to generate the musical tone of the specific part.

As a result, at the timing instructed by the sounding instructing means, the note length instructed by the sounding instructing means,
A musical tone according to the pitch and velocity data in the automatic performance data stored in the storage means is sounded. Therefore,
For example, when a keyboard is used as the sounding instruction means, the performer only needs to perform a simple operation of giving a sounding start timing and a pressing time on the keyboard without worrying about the key to be pressed and the strength of the key. Since the musical sound of the particular part is generated, the player can enjoy the automatic performance as if he or she were playing the particular part. In this case, since the note length is determined according to the key release, it is possible to perform an automatic performance that reflects the intention of the performer not only in the sounding timing but also in the note length.

According to a fifth aspect of the invention, in the automatic musical instrument of the electronic musical instrument, the parts other than the specific part selected from the plurality of parts generate automatic musical sounds in synchronization with the tempo. When a sounding instruction is issued, a particular part is sounded according to the note length and velocity instructed by the sounding instructing means and the data for determining the pitch of the automatic performance data stored in advance in the storage means. In other words, the tone generation timing, the note length, and the velocity are designated by the tone generation instructing means, and the pitch is designated by the automatic performance data to generate the musical tone of the specific part.

As a result, at the timing instructed by the sounding instructing means, a musical tone is generated in accordance with the note length and velocity instructed by the sounding instructing means and the pitch data in the automatic performance data stored in the storage means. To be done. Therefore,
For example, when a keyboard is used as the sounding instructing means, the performer does not have to worry about the key to be pressed, but simply performs a simple operation of giving the sounding start timing, the pressing time and the velocity on the keyboard. Since the musical sound of the part is generated, the performer can enjoy the automatic performance as if playing the particular part. In this case, since the note length and velocity are determined according to the key depression, it is possible to perform an automatic performance that reflects the player's will with respect to not only the sounding timing but also the note length and velocity. Suitable automatic performance can be performed.

In each of the above inventions, the case where the keyboard is used as the sounding instructing means has been described. However, as the sounding instructing means, for example, an external interface for inputting performance data from the outside can be used.

The operations shown in the above flow chart are all C
It is realized by the processing of the PU 10.

(1) Main Processing FIG. 3A is a flowchart showing a main routine of an electronic musical instrument to which the automatic musical instrument of the present electronic musical instrument is applied.
It is started by turning on the power. That is, when the power is turned on, first, initialization processing is performed (step S10).
In this initialization processing, the internal hardware of the CPU 10 is set to the initial state, and the registers, counters, flags, etc. defined in the RAM 12 are set to the initial state. Also, in this initialization processing, processing for preventing generation of unnecessary sound when the power is turned on is performed by sending predetermined data to the sound source 17. Furthermore,
In this initialization processing, various I / O ports (not shown) are also initialized.

Upon completion of this initialization processing, panel processing is then carried out (step S11). In this panel processing, processing corresponding to the operation of each switch of the operation panel 13 is performed. Details of this panel processing will be described later.

Then, an automatic performance process is performed (step S12). In this automatic performance process, if an automatic performance is being performed, a process of producing a sound based on the automatic performance data stored in the ROM 11 is performed. Details of this automatic performance process will be described later.

Next, keyboard processing is performed (step S
13). In this keyboard processing, sounding or muffling processing that accompanies depression or key release of the keyboard device 14 is performed. In addition, a tone generation process utilizing automatic performance data, which is a feature of the present invention, is also performed. The details of this keyboard processing will be described later.

Next, external input data processing is performed (step S14). This external input data processing is processing corresponding to the data input from the external interface 14. For example, when the data input from the external interface 14 is a MIDI message,
If note-on or note-off data is input,
The same processing as the keyboard processing described later is performed. Further, for example, when a control change message is input, the same processing as the panel processing described later is performed. Therefore, description of the details of this external input data processing is omitted.

Thereafter, the process returns to step S11, and step S
The processes of 11 to S14 are repeatedly executed. When an event based on panel operation or keyboard operation occurs or data is input from the external interface 14 in the process of this repeated execution, processing corresponding to those is performed, and sound generation processing based on automatic performance data is performed. As a result, various functions as an electronic musical instrument or an automatic musical instrument are realized.

(2) Timer Interrupt Process The timer interrupt process is a process that is performed by interrupting each process of the main routine according to an interrupt signal generated from a timer built in the CPU 10.

In this timer interrupt process, clock increment is performed (step S15). That is, RAM
The contents of the clock counter provided in 12 are incremented. The contents of the clock counter are referred to in the automatic performance processing described later and are used to determine whether or not the timing for determining whether or not to perform the sound generation processing (hereinafter referred to as "sound generation processing timing") has arrived. . This sound generation processing timing is also used as the timing for decrementing the gate time of the sound being sounded.

When this clock increment process is completed, the process returns from this timer interrupt routine and returns to the interrupted position of the main routine.

(3) Panel Processing Next, details of the panel processing performed in step S11 of the main routine will be described with reference to the flowchart of FIG.

In the panel processing, first, panel data is fetched (step S20). That is, CPU1
0 acquires panel data (hereinafter referred to as “new panel data”) from the operation panel 13 and stores it in the new panel data area of the RAM 12. Then, it is checked whether or not the start / stop switch 131 is turned on (step S21). This is because the bit corresponding to the start / stop switch 131 of the new panel data is "1".
And the panel data stored in the old panel data area that was captured in the previous panel processing (hereinafter,
It is called "old panel data". ) Is performed by checking whether the bit corresponding to the start / stop switch 131 is “0”. Mode switch 1 below
32, part selection switch 133 and music selection switch 13
The determination as to whether or not 4 is turned on is performed in the same manner as above. Although not shown, the new panel data is stored in the old panel data area at the end of this panel processing routine.

When it is determined in step S21 that the start / stop switch 131 is turned on, it is then checked whether or not play is in progress (step S22). This is done by checking whether the play flag is "1". The same applies below. If it is determined that the game is being played, the play flag is cleared to "0", and the mute processing is performed (step S23). At this time, a message indicating that the automatic performance is stopped is displayed on the display device 130. The muffling process is realized by sending predetermined data to the sound source 17. This realizes a function of stopping the automatic performance by pressing the start / stop switch 131 during the automatic performance.

On the other hand, if it is determined in step S22 that the play is not in progress, the play flag is set to "1", and the address initialization processing of each part is performed (step S24). At this time, a message indicating that the automatic performance is being performed is displayed on the display device 130. By this processing, the start address of the automatic performance data of each part is set in the address register provided for each part. This enables the start / stop switch 1 while the automatic performance is stopped.
The function of starting automatic performance of each part from the beginning is realized by pressing 31. If it is determined in step S21 that the start / stop switch 131 is not turned on, steps S22-
The process of S24 is skipped.

Then, it is checked whether or not the mode switch 132 is turned on (step S25). If it is determined that the mode switch 132 is turned on, it is then checked whether or not play is in progress (step S26). Then, if it is determined that the game is not being played, then it is checked whether or not it is the special mode (step S27). This is done by examining the mode flags. The same applies below. When it is determined that the special mode is set, the mode flag is cleared to "0" (step S28). On this occasion,
A message indicating that the mode is the normal mode is displayed on the display unit 130. On the other hand, if it is determined that the mode is not the special mode, the mode flag is set to "1" (step S2).
9). At this time, a message indicating the special mode is displayed on the display device 130. This allows the mode switch 1
The function of inverting the normal mode and the special mode each time 32 is pressed is realized.

If it is determined in step S26 that the game is being played, steps S27 to S29 are skipped. In other words, the operation of the mode switch 132 during the automatic performance is invalid. If it is determined in step S25 that the mode switch 132 is not turned on, the processes in steps S26 to S29 are skipped.

Then, it is checked whether or not the part selection switch 133 is on (step S30). Here, if it is determined that the part selection switch 133 is turned on, then it is checked whether or not play is in progress (step S31). When it is determined that the play is not in progress, the trigger part is changed (step S32). That is, the content of the part number register is incremented. At this time, the number of the trigger part is displayed on the display device 130. On the other hand, if it is determined that the game is being played, this step S32 is skipped. In other words, the operation of the part selection switch 133 during the automatic performance is invalid. In addition, the above step S3
When it is determined that the part selection switch 133 is not turned on at 0, the processes of steps S31 to S32 are skipped.

Next, it is checked whether the music selection switch 134 is on (step S33). Here, when it is determined that the music selection switch 134 is turned on,
Then, it is checked whether or not the game is being played (step S34). When it is determined that the song is not being played, the song is changed (step S35). That is, the content of the song number register is incremented. At this time, the song number is displayed on the display unit 130.
After that, the process returns from this panel processing routine and returns to the main routine. On the other hand, if it is determined that the game is being played, this step S35 is skipped. In other words, the operation of the music selection switch 134 during the automatic performance is invalid. If it is determined in step S33 that the music selection switch 134 is not turned on, the processes of steps S34 and S35 are skipped, and the process returns from this panel process routine to the main routine.

(4) Automatic Performance Processing Next, details of the automatic performance processing performed in step S12 of the main routine will be described with reference to the flowchart of FIG.

In the automatic performance process, first, it is checked whether or not the clock is "0" by referring to the contents of the clock counter (step S40). When it is determined that the clock is "0", the following processing is not performed and the routine returns from the automatic performance processing routine to the main routine. This is because the clock was decremented in the previous automatic performance process (step S41) and "0".
This is the process in the case where the timer interruption has not occurred since the setting was turned on, that is, the predetermined time (time corresponding to one step time) has not elapsed and the sound generation processing timing has not yet come.

On the other hand, when it is determined that the clock is not "0", it is recognized that the tone generation processing timing has arrived after the predetermined time has elapsed, and the clock is decremented (step S41). Then, it is checked whether or not the game is being played (step S42). When it is determined that the play is not in progress, the following process is not performed and the process returns from the automatic performance process routine to the main routine. In this way, the automatic performance stop function is realized by the processing that the sound generation processing based on the automatic performance data is not performed when not playing.

When it is recognized in the step S42 that the game is being played, a gate time process is then performed (step S43). This process decrements the gate time (stored in the automatic performance data processing (step S48) described later) stored in the sounding register provided in the RAM 12 for all sounds being sounded. , This is the process of muting the sound whose decrement result is zero. As a result, the function of pronouncing only the note length given at the gate time is realized.

Then, step time increment processing is performed (step S44). In this step increment process, the content of the step time counter is incremented. Here, the step time counter is a counter provided in the RAM 12, and is used, for example, to count the elapsed time from the beginning of the bar. Next, the processing part is initialized to "0" (step S4).
5). Here, the processing part is a part that is about to be subjected to sound generation processing, and “processing part = 0” corresponds to, for example, a rhythm part. "Processing part =
“1” is assigned to the chord part, “processing part = 2” is assigned to the bass part, and “processing part = 3” is assigned to the melody part.

Next, it is checked whether or not the special mode is in progress (step S46). If it is recognized that the special mode is not set, the process branches to step S48 to generate an automatic performance sound. On the other hand, if it is determined that the special mode is in progress, then it is checked whether the processing part is the trigger part (step S47). this is,
This is done by checking whether the number of the trigger part stored in the part number register matches the number of the processing part. If it is determined that the processing part is the trigger part, the automatic performance data processing is not performed in order to suppress the generation of the automatic performance sound, and the step S49 is performed.
Go to. The sound of the processing part is performed by the keyboard processing described later. On the other hand, when it is determined that the processing part is not the trigger part, the process proceeds to step S48 in order to generate the automatic performance sound of the part.

At step S48, automatic performance data processing is performed. That is, in this automatic performance data processing, the contents of the step time counter are first compared with the step time data in the set of automatic performance data read from the position designated by the address register of the ROM 11. When they match, it is determined that the sound generation timing has arrived, and sound generation processing is performed. That is, the key number, velocity and gate time in the automatic performance data read from the ROM 11 are stored in the sounding register. Then, the tone color parameters corresponding to the key number and velocity are read from the ROM 11 and sent to the sound source 17. As a result, a musical tone corresponding to the automatic performance data is generated.

Then, the processing part is incremented (step S49), and it is checked whether or not the processing part becomes "4" (step S490). here,
If it is determined that the processing part is not "4", it is determined that the processing for all parts is not completed,
Returning to step S46, the process for the next part is performed. On the other hand, when it is determined that the processing part has reached "4", it is determined that the processing for all parts has been completed, and the process returns from the automatic performance processing routine to the main routine.

(5) Keyboard Processing Next, the details of the keyboard processing performed in step S13 of the main routine will be described with reference to the flowchart of FIG.

In the keyboard process, the key number is first initialized (step S50). In this keyboard processing routine,
The presence or absence of a key event is checked for each key, and when there is an event, a sounding or muffling process corresponding to the key is performed. This process is sequentially performed from the key with the key number “0”. More specifically, in this step, the content of the key number register provided in the RAM 12 for storing the key number is cleared to "0".

Then, the presence or absence of an event is checked (step S51). That is, the event signal fetched from the keyboard scan circuit 15 is examined by the method described above.
If the event signal indicates that there is no key event, the key depression or key release processing corresponding to the key is not performed, and the process branches to step S58. On the other hand, if the event signal indicates that there is a key event, it is checked whether the type of event is an on event or an off event (step S52). If it is determined here that the event is an on-event, then it is checked whether or not the special mode and the play are in progress (step S5).
3). This is done by checking whether both the mode flag and the play flag are "1". The same applies below.

When it is determined that the special mode and the play are being performed, sound is generated based on the automatic performance data of the trigger part (step S54). That is, the key number and touch data (velocity) obtained from the keyboard scan circuit 15 are ignored, and the automatic performance data designated by the address register corresponding to the trigger part selected at that time is read from the ROM 11. Sound is generated based on the key number and velocity included in the automatic performance data. That is, the key number, velocity and gate time in the read automatic performance data are stored in the sounding register, and the tone color parameters corresponding to these key number and velocity are read from the ROM 11 and sent to the tone generator 17. A musical tone having a pitch and intensity corresponding to the automatic performance data is generated. In addition, the length of the note sounded here (note length) is the gate time included in the automatic performance data (gate time stored in the register during sound generation), regardless of the key release timing.
Determined by

By the above processing, at the timing when the player presses a key, the musical tone of the pitch, velocity and note length to be originally played automatically is produced regardless of the position, strength and key pressing time of the key pressed. Is generated. This means that the performer
This means that only the sounding timing needs to be specified on the keyboard 16.

If it is determined in the above step S53 that the special mode is not being played and the play is not being performed, a sound corresponding to the depressed key is sounded (step S55). That is,
The tone number parameter corresponding to the key number and touch data (velocity) obtained from the keyboard scan circuit 15 is RO.
It is read from M11 and sent to the sound source 17. As a result, a musical tone having a pitch and intensity corresponding to the key depression operation is generated.

When it is determined in step S52 that the event is an off event, it is then checked whether or not the special mode is in progress and the play is in progress (step S56). If it is determined that the game is in the special mode and the game is being played, the mute processing is not performed and the process branches to step S58.
This is because the muffling timing in the special mode is managed by the gate time, so it is not necessary to perform the muffling process.

On the other hand, if it is determined that the key is in the special mode and not in play, the mute corresponding to the released key is performed (step S57). This is realized by sending predetermined data to the sound source 17.

Upon completion of the above-mentioned sound generation and mute processing, the key number is then incremented (step S5).
8) Then, it is checked whether or not the process is finished (step S).
59). Whether or not this is the end is determined by whether or not all the keys (for example, 88 keys) of the keyboard 16 have been processed. When it is determined that the processing is not finished, the process returns to step S51, and the process for the next key is performed. On the other hand, if it is determined that the process is finished, the process returns from this keyboard processing routine and returns to the main routine.

As described above, according to the first embodiment, in the automatic musical instrument of the electronic musical instrument, the parts other than the trigger part selected from the plurality of parts generate the automatic musical tone in synchronization with the tempo, When the keyboard 16 issues a sounding instruction, the trigger part is sounded according to the data for determining the pitch, the note length and the velocity of the automatic performance data stored in advance in the ROM 11. In other words, the tone generation timing is specified by the keyboard 16, and the pitch, note length and velocity are specified by the automatic performance data to generate the musical sound of the trigger part.

As a result, at the timing designated by the keyboard 16, a musical tone according to the pitch, note length and velocity data in the automatic performance data stored in the ROM 11 is produced. Therefore, the performer does not care about the key to be pressed, the key pressing time, and the strength of the key pressing at all, and simply performs a simple operation of giving only the timing of starting the sounding on the keyboard 16 to the trigger part. Since an original musical tone (a musical tone having a pitch, a note length and a velocity according to the automatic performance data) is generated, the performer can enjoy the automatic performance as if he / she is playing the trigger part.

(Embodiment 2) In Embodiment 2, the tone generation timing and velocity are specified by the keyboard 16, and the pitch and note length are specified by the automatic performance data to generate the musical sound of the trigger part.

60). That is, the key number obtained from the keyboard scan circuit 15 is ignored and only the touch data (velocity) is adopted. On the other hand, the automatic performance data designated by the address register corresponding to the trigger part selected at that time is read from the ROM 11, the velocity contained in the automatic performance data is ignored, and the key number and the gate time are adopted. .

The tone number parameter corresponding to the key number and gate time in the automatic performance data and the touch data (velocity) from the keyboard scan circuit 15 is RO.
It is read from M11 and sent to the sound source 17. As a result, a musical tone having a pitch and a note length according to the automatic performance data is generated with a strength according to the key depression.

As described above, according to the second embodiment, in the automatic musical instrument of the electronic musical instrument, the parts other than the trigger part selected from the plurality of parts generate the automatic musical tone in synchronization with the tempo, When a sound is instructed by the keyboard 16, the velocity of the keyboard 16 and the key number and gate time data for determining the pitch and the note length of the automatic performance data stored in the ROM 11 in advance are used for the trigger part. Pronunciation is made.
In other words, the pronunciation timing and velocity are on the keyboard 16.
Then, the pitch and the note length are specified by the automatic performance data to generate the musical sound of the trigger part.

As a result, at the timing designated by the keyboard 16, the velocity designated by the keyboard 16 and the RO
A musical tone according to the pitch and note length data in the automatic performance data stored in M11 is generated. Therefore, the player can generate the musical sound of the trigger part only by performing a simple operation of giving the timing of starting the sound generation and the strength of the key pressing on the keyboard without worrying about the key to be pressed and the key pressing time. Therefore, the player can enjoy the automatic performance as if he / she is playing the trigger part. In this case, since the strength of the sound is determined according to the key depression, it is possible to perform the automatic performance in which not only the sounding timing but also the strength of the sound reflects the player's will.

The present invention may be modified and configured as follows. That is, in an automatic musical instrument of an electronic musical instrument in which parts other than a specific part selected from a plurality of parts generate automatic musical sounds in synchronization with tempo, at least a pitch and a note length for generating a musical sound of the specific part.

Step S70 in the keyboard processing routine (FIG. 6) of the first embodiment.
Is newly added. Therefore, the steps performing the same processing are denoted by the same reference numerals as those in FIG. 6, and description thereof will be omitted.

When it is determined in step S56 of the flow chart shown in FIG. 8 that the special mode and the play mode are in effect, the sound being sounded by the trigger part is muted (step S70). That is, in step S54, the sound is generated based on the automatic performance data of the trigger part (see the description of the first embodiment), but the length of the sound generated here (note length) is the gate time included in the automatic performance data. It is determined by the key release timing regardless of (gate time stored in the register during sound generation). That is, the sound is muted when an off event of the keyboard 16 occurs.

As described above, according to the third embodiment, in the automatic musical instrument of the electronic musical instrument, the parts other than the trigger part selected from the plurality of parts generate the automatic musical tone in synchronization with the tempo, When the keyboard 16 issues a sounding instruction, the sounding of the trigger part is performed according to the note length specified by the keyboard 16 and the data for determining the pitch and velocity of the automatic performance data stored in the ROM 11 in advance. . In other words, the tone generation timing and note length are specified on the keyboard 16, and the pitch and velocity are specified by the automatic performance data to generate the musical sound of the trigger part.

As a result, at the timing designated by the keyboard 16, the note length designated by the keyboard 16 and the ROM 1

Therefore, the player can generate the musical sound of the trigger part only by performing a simple operation of giving the timing of starting sound generation and the pressing time on the keyboard 16 without worrying about the key to be pressed and the strength of the key press. Therefore, the player can enjoy the automatic performance as if he / she is playing the trigger part. In this case, since the note length is determined according to the key release, it is possible to perform an automatic performance that reflects the intention of the performer not only in the sounding timing but also in the note length.

60). That is, the key number obtained from the keyboard scan circuit 15 is ignored and only the touch data (velocity) is adopted. On the other hand, the automatic performance data designated by the address register corresponding to the trigger part selected at that time is read from the ROM 11, and the velocity contained in the automatic performance data is ignored and only the key number is adopted.

A tone number parameter corresponding to the key number in the automatic performance data and the touch data (velocity) from the keyboard scan circuit 15 is read from the ROM 11 and sent to the tone generator 17. As a result, a musical tone having a pitch and a note length according to the automatic performance data is generated with a strength according to the key depression.

On the other hand, when it is determined in step S56 that the special mode and the play are being performed, the sound being sounded by the trigger part is muted (step S70). That is,
In step S70, a musical tone based on the automatic performance data of the trigger part is generated with a strength corresponding to the key depression of the keyboard 16 (see the explanation of the second embodiment), but the length of the tone generated here (note length). Is determined by the key release timing regardless of the gate time (gate time stored in the register during sound generation) included in the automatic performance data. That is, the sound is muted when an off event of the keyboard 16 occurs.

In other words, the tone generation timing, note length, and velocity are specified on the keyboard 16, and the pitch is specified by the automatic performance data to generate the musical sound of the trigger part.

As a result, at the timing designated by the keyboard 16, a musical tone according to the note length and velocity designated by the keyboard 16 and the pitch data in the automatic performance data stored in the ROM 11 is produced. Therefore, the performer can generate the musical sound of the trigger part only by performing a simple operation of giving the timing of starting the sounding, the pressing time and the velocity on the keyboard without worrying about the key to be pressed. The person can enjoy the automatic performance as if playing the trigger part. In this case, since the note length and velocity are determined according to the key depression, it is possible to perform an automatic performance that reflects the player's will with respect to not only the sounding timing but also the note length and velocity. Suitable automatic performance can be performed.

Also in the case of the fourth embodiment, a selection switch is provided on the operation panel 13 to select whether the velocity and the note length are controlled by the keyboard 16 or according to the velocity and the gate time in the automatic performance data.
