Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a singing voice reproducing apparatus for an electronic musical instrument, which reproduces a singing voice (vocal) according to the operation of an operator.

[0002]

2. Description of the Related Art Recent electronic musical instruments are capable of generating musical tones with various musical instrument sounds (timbres). Such a function corresponds to a tone color by, for example, preliminarily sampling waveform signals of various tones and storing them as waveform data in a memory, and selecting a specific tone color with a tone color selection switch provided on the operation panel, for example. This is realized by reading the waveform data, reconstructing it into a tone signal, and supplying this to a speaker, for example.

By the way, in the electronic musical instrument as described above, it is easily inferred that a musical tone simulating a human voice can be generated by considering not only musical instrument sounds but also human voice as one timbre. That is, the waveform signal of the human voice is sampled and stored in the memory as the waveform data, the waveform data is read by the same method as described above, regenerated into a musical tone signal, and the human voice is emitted through the speaker. That is, it is possible to generate a musical sound by voice.

Further, in the same manner, waveform signals of various voices uttered by a person are sampled and stored as waveform data, and these are appropriately combined and reconstructed to reconstruct a phrase having a predetermined meaning. It is possible.
In other words, the electronic musical instrument can be made to speak. This means that a singing voice (vocal) can be generated by an electronic musical instrument if a pitch is added to each sound and the sounding time of each sound is controlled when the phrase is reproduced.

On the other hand, since an electronic musical instrument capable of reproducing a singing voice can be applied in various ways, there is a strong demand for its development.
For example, the following applications are possible. That is, when a melody is composed first and the lyrics are written in accordance with the melody, the lyrics of the lyrics are input to the electronic musical instrument as the lyrics data and stored therein, and the stored lyrics data is sequentially read and matched to the melody. It is possible to check whether or not the melody and the lyrics match by making the pronunciation.

On the contrary, even when the lyrics are first created and the melody is composed later, the melody can be added while the pre-stored lyrics are sequentially read and pronounced, so that the melody that matches the lyrics can be created. Will be easier.

Further, when the song or the song is composed, if the voice of the singer who wants to sing the song is sampled and stored as waveform data, a singer that matches the composer's or the songwriter's idea can be selected. Since the voice of the singer can reproduce the singing voice of the song related to the song or song, it is possible to create a song in a good environment.

[0008]

By the way, in order to reproduce the above-mentioned singing voice, it is necessary to regard each voice uttered by a person as one timbre and to prepare the waveform data of each voice in advance. . That is, similar to the waveform data corresponding to each timbre of the conventional electronic musical instrument, at least 50 or more sounds (100 including 100 voices, semi-voiced voices, and other various voices).
It is necessary to prepare the waveform data corresponding to the voice (about sound). Then, in order to reproduce the desired lyrics, it is necessary to sequentially select voices corresponding to the lyrics.

However, it is not practical to select such a voice by using the tone color selection switch provided on the operation panel, unlike the tone color selection in the conventional electronic musical instrument.
That is, in the conventional electronic musical instrument, when a specific tone color is selected by the tone color selection switch, the tone color is produced thereafter. Therefore, it is theoretically possible to play while dynamically changing the voice using the tone color selection switch, but it is necessary to provide a large number of operators corresponding to the type of voice, and when playing, Since it is necessary to search for and operate an operator for producing a desired voice from a large number of operators, it is almost impossible to perform a singing voice in real time.

It is also conceivable that lyrics data is stored in the sequencer in advance as tone color information and the performance is performed by singing voice while sequentially reading out this tone color information, that is, while dynamically changing the tone color. Since the timing of changing the tone color depends on the data stored in advance, only the tone color can be changed at a fixed timing.

The present invention has been made in view of the above circumstances, and provides a singing voice reproducing apparatus for an electronic musical instrument, which has a simple structure but is excellent in operability and can freely reproduce a singing voice by a simple operation. The purpose is to do.

[0012]

In order to achieve the above object, a singing voice reproducing apparatus for an electronic musical instrument according to the present invention comprises a keyboard operator for instructing a pitch, a storage means for storing lyrics data,
Instructing means for instructing that the lyrics data should be read from the storing means, reading means for sequentially reading the lyrics data from the storing means when there is an instruction by the instructing means, and lyrics data read by the reading means And a sound source for generating a singing voice of a pitch instructed by the keyboard operator with a tone color according to the above.

Further, in the singing voice reproducing apparatus for an electronic musical instrument of the present invention, the instructing means is a panel operator.

Further, in the singing voice reproducing apparatus for an electronic musical instrument of the present invention, the instructing means is a keyboard operator.

In the singing voice reproducing apparatus for an electronic musical instrument of the present invention, the input means is a pedal operator.

For the same purpose as described above, the electronic musical instrument singing voice reproducing apparatus of the present invention has a storage means for storing lyrics data, a keyboard operator for instructing a pitch, and an instruction by the keyboard operator. Read means for sequentially reading the lyrics data from the storage means, and a sound source for generating a singing voice of a pitch designated by the keyboard operator with a tone color according to the lyrics data read by the reading means. It is characterized by that.

[0017]

In the present invention, the lyrics data is stored in the storage means in advance, and the lyrics data stored in the storage means is sequentially read out by instructing by the instruction means, and the tone color is changed based on the lyrics data. Be seen. That is, a voice (timbre) instructed by the lyrics data can be generated by instructing by the instructing means. When the keyboard operator is operated in this state, the voice (tone) previously instructed by the instructing means
Generates a musical tone having a pitch designated by the keyboard operator, that is, a singing voice.

As a result, the singing voice can be reproduced only by providing the instruction means for giving the timing for reading the lyrics data, so that many operations are required as in the case of changing the voice using the conventional tone color selection switch. There is no need to provide a child, which simplifies the configuration. Further, since the number of operators is small, it is not necessary to search for an operator for producing a desired voice as in the conventional case, and it becomes easy to reproduce a singing voice in real time.

Further, since the timing for reading the lyrics data, that is, the timing for switching the voice can be freely selected, the degree of freedom in generating a singing voice is increased and the usability is excellent.

By using a panel operator, a specific key in the keyboard operator or a pedal operator as the instructing means, a person who is accustomed to playing an electronic musical instrument can perform a quick operation and is excellent in usability. It has become a thing.

Further, in the present invention, the lyrics data is stored in the storage means in advance, and the lyrics data stored in this storage means is sequentially read out by the operation of the keyboard operator to change the tone color. Along with this, the musical tone is generated with a predetermined tone color (sound) and pitch, that is, a singing voice is generated by being sounded at the pitch designated by the keyboard operator.

Thus, the voice can be switched and the pitch can be instructed at the same time by operating the keyboard operator without performing any special operation for switching the voice, so that the singing voice can be generated more easily. Has become.

It can also be configured to load zero. According to this configuration, it is possible to make an application in which a plurality of types of lyrics data are created and stored in the storage medium, and desired lyrics data can be read and reproduced as a singing voice as needed.

The tone color sequence memory 120 is also used.
May be provided in the ROM 11. In this case, the lyrics stored in advance in the ROM 11 cannot be changed, but it is possible to play the song along the lyrics.

As shown in FIG. 3, for example, the operation panel 14a is provided with various switches for controlling the electronic musical instrument, an LED display for displaying ON / OFF of each switch, and the like. The switches are arranged in a logical matrix in the internal circuit, and are scanned by the switch scan circuit 13 described later for each row (or column).

The switches provided on the operation panel 14a include, for example, a tone color selection switch, a rhythm selection switch, an effect selection switch, a volume control switch, a tone color sequence switch 140 and the like.

The tone color selection switch is "vocal, piano,
It is used to select various tones such as "flute, ..., Violin". The rhythm selection switch is used to select various rhythms such as "waltz, samba, ..., Disco". The effect selection switch is used to specify the type of effect to be imparted to a musical sound such as "reverb, chorus, ...". The volume control switch is used to control the volume of the volume.

The tone color sequence switch 140 corresponds to an instruction means (panel operator), and is effective when "vocal" is selected by the tone color selection switch. Tone sequence switch 140
Is used to change the tone color by reading the tone color sequence data (lyric data) from the tone color sequence memory 120 each time the button is pressed, that is, to switch the voice.

The pedal 14b is composed of, for example, a foot pedal, and serves as an expression pedal for changing the volume according to the amount of depression, and as an instruction means (pedal operator) provided on both sides of the expression pedal. Foot switch (none shown)
It is composed by.

The operation panel 14a configured as described above
The pedal 14b is connected to the CPU 10 via the switch scan circuit 13 and the system bus 30.

The switch scan circuit 13 controls data transmission / reception between the operation panel 14a or the pedal 14b and the CPU 10. That is, when the switch scan circuit 13 sends a scan signal to the operation panel 14a, the operation panel 14a returns a signal indicating the on / off state of each switch to the switch scan circuit 13 in response to the scan signal.

When the switch scan circuit 13 sends a scan signal to the pedal 14b, the pedal 14b
In response to the scan signal, the switch scan circuit 13 b outputs a signal indicating the on / off state of the foot switch and data indicating the depression amount of the expression pedal.
Return to. The switch scan circuit 13 sends the above signals received from the operation panel 14a or the pedal 14b to the CPU 10 via the system bus 30 as panel data or pedal data.

The keyboard 16 corresponds to a keyboard operator and has a plurality of keys for instructing a pitch. A specific key (for example, the lowest tone key) of the keyboard 16 is used as an instruction means (keyboard operator) for changing the voice. As the keyboard 16, for example, a two-contact type keyboard is used. That is, each key of the keyboard 16 has two key switches which are opened and closed in association with the key pressing / key releasing operation, so that the key touch can be detected. This keyboard 16 has a CPU 1 via a key scan circuit 16 and a system bus 30.
It is connected to 0.

The key scan circuit 15 detects touch data indicating the key number of the key pressed or released and the speed (strength) of key depression or release. That is, the key scan circuit 15 sends a scan signal to the keyboard 16, and the keyboard 16 sends a signal indicating the on / off state of the first and second key switches in response to the scan signal. Return to 15.

The key scan circuit 15 includes a keyboard 16
An event signal including a signal indicating the presence or absence of a key event and a signal indicating the type of the key event (on event or off event) from the signal indicating the on / off state of the first and second key switches received from To do. Further, the key scan circuit 15 detects the key number of the key pressed or released, and measures the time from when the first key switch is turned on until when the second key switch is turned on. Generate touch data indicating the key pressing or key releasing speed. The event signal, the key number, and the touch data thus detected or generated are sent to the CPU 10 as key data.

The sound source 17 is a tone generation circuit having a plurality of oscillators. That is, the sound source 17 receives the sound generation parameter and the sound generation start command from the CPU 10 and receives the waveform memory 2
The waveform data stored in 1 is read out, an envelope is added to the waveform data, and a digital tone signal is generated and output.
Further, in response to the tone generation end command from the CPU 10, the reading of the waveform data stored in the waveform memory 21 is finished, and the output of the digital tone signal is stopped.

The waveform memory 21 is composed of, for example, a ROM. In the waveform memory 21, waveform data of a plurality of types of musical instrument sounds corresponding to each tone color parameter and various waveform data of human voices (a, a, c, ...) Are stored in the waveform memory 21. Waveform data for each voice) is stored. The waveform data stored in the waveform memory 21 is created, for example, by converting emitted musical tones or generated voices into electric signals and performing pulse code modulation (PCM) on the electric signals. The waveform data stored in the waveform memory 21 is read by the sound source 17.

The D / A converter 18 converts the digital musical tone signal sent from the sound source 17 into an analog musical tone signal. The output of the D / A converter 18 is supplied to the sound system 19.

The sound system 19 is composed of an amplifier and various effect imparting circuits. That is, the sound system 19 amplifies the input analog musical tone signal in accordance with the designation of the volume control switch and the pedal 14b, and performs processing for producing acoustic effects such as reverb and chorus. The analog tone signal amplified and processed by the sound system 19 is supplied to the speaker 20.

The speaker 20 is a well-known one which converts an analog musical tone signal as an electric signal into an acoustic signal and outputs it. Musical sounds or singing voices are emitted by the speaker 20.

Next, the operation of the electronic musical instrument having the above structure will be described with reference to the flow charts of FIGS. The tone color sequence memory 120 is
It is assumed that the lyrics data has already been stored.

FIG. 4 is a flow chart showing the main routine of this electronic musical instrument, which is started by turning on the power. That is, when the power is turned on, first, initialization processing is performed (step S10).

This initialization process is a process of setting the internal state of the CPU 10 to the initial state and also setting the registers, counters or flags defined in the RAM 12 to the initial state.

In this initialization processing, the tone color sequence counter N related to the present invention is set to an initial value (start address -1 address of the tone color sequence memory 120), and the vocal flag is cleared to "0". The tone color sequence counter and the vocal flag are both RA.
A counter and a flag provided in M12. Also,
In this initialization process, by sending predetermined data to the sound source 17, a process of preventing unnecessary sound from being generated when the power is turned on is also performed.

When this initialization processing is completed, panel processing is performed (step S11). Details of this panel process are shown in the flowchart of FIG.

In the panel processing, first, it is checked whether or not there is a panel event (step S20). This is done as follows. That is, first, the switch scan circuit 13 scans the panel switch of the operation panel 14a, the foot switch and the expression pedal of the pedal 14b, and the data indicating the on / off state of each switch and the data indicating the depression amount of the expression pedal (hereinafter, These are called "new panel data".

Then, in the same manner as described above, the RAM 12 has already been read from the previous operation panel 14a and pedal 14b.
The data (hereinafter referred to as "old panel data") stored in the above is compared with the new panel data, and a panel event map in which different bits are turned on is created.
If there is a bit that is turned on in this panel event map, it is determined that there is a panel event.

If it is determined in step S20 that there is no panel event, the following processing is not performed and
The process returns from this panel processing routine and returns to the main routine.

On the other hand, when it is judged in the step S20 that there is a panel event, it is checked whether or not the panel event is an event of a vocal switch which is one of the tone color selection switches (step S2).
1). This is done by checking if the bit corresponding to the vocal switch in the panel event map is on.

If it is determined that the event is a vocal switch event, then the vocal flag is set to "1" (step S22). This vocal flag is set in the panel switch process (step S
In 25), it is cleared when it is detected that a switch other than the vocal switch in the tone color selection switch is turned on. If it is determined in step S21 that the event is not a vocal switch event, step S22
Processing is skipped.

Next, it is checked whether or not the event is the tone color sequence switch 140 (step S2).
3). This is done by checking whether the bit corresponding to the timbre sequence switch 140 in the panel event map is turned on. If it is determined that the event is not the tone color sequence switch 140 event, panel switch processing is performed on other panel switches (step S25).

In the panel switch process, for example, a tone color changing process for an event of a switch other than the vocal switch in the tone color selecting switch, a rhythm changing process for an event of the rhythm selecting switch, a volume changing process for an event of the volume control switch, or a sound. A process of giving a predetermined acoustic effect to the event of the effect switch is performed. Since the contents of the processing corresponding to each of these switches are not directly related to the present invention, the description thereof will be omitted. After that, the process returns from this panel processing routine and returns to the main routine.

On the other hand, when it is determined in step S23 that the event is the tone color sequence switch 140, then it is determined whether the vocal flag is "1", that is, the state where the vocal switch of the tone color selection switch is pressed. Is checked (step S24). If it is determined that the vocal flag is not "1", that is, the vocal switch of the tone color selection switch is not pressed, the process branches to step S25 in order to process the events of other switches.

On the other hand, when it is determined that the vocal flag is "1", the tone color sequence changing process is performed (step S26).

The details of the tone color sequence changing process are shown in the flowchart of FIG. In the tone color sequence changing process, first, the content of the tone color sequence counter N is incremented (step S30).

Next, a tone color changing process is performed (step S31). That is, one character of lyrics data is read from the position indicated by the tone color sequence counter N of the tone color sequence memory 120 and set in a tone color buffer (not shown). The tone color buffer is a buffer provided in the RAM 12 and is used to determine a tone color for the next tone generation.

Thereafter, the control returns from the tone color sequence changing processing routine to the panel processing routine, and further returns from the panel processing routine to return to the main routine.

In the main routine, keyboard processing is then carried out (step S12). Details of this keyboard processing are shown in the flowchart of FIG.

In the keyboard processing, it is first checked whether or not there is a key event (step S40). The determination of the presence / absence of this key event is made by fetching the key data from the key scan circuit 15 and examining the signal indicating the presence / absence of the event in the event signal included in this key data. At this time, data such as the type of key event, key number, and touch data is stored in a predetermined area of the RAM 12.

If it is determined that there is no key event, the following processing is not performed and the processing returns from this keyboard processing routine to the main routine.

On the other hand, when it is determined that there is a key event, it is checked whether or not the event is a key-on event (step S41). This is performed by checking the data indicating the type of event included in the key data stored in the RAM 12 in step S40.

If it is determined that the event is a key-on event, channel allocation processing is performed (step S42). In this channel allocation processing, a free channel of the sound source 17 is searched, if there is a free channel, a sound is assigned to that channel, and if there is no free channel,
This is a process in which the pronunciation of a predetermined channel is stopped and the pronunciation is assigned to that channel.

Next, the tone generation parameter is set to the assigned channel (step S43). In this processing, a tone generation parameter is read from the ROM 11 based on the tone color set in the tone color buffer at that time and the key number and the touch data in the key data stored in the RAM 12, and is assigned to the sound source 17. This is the process of sending to the channel.

Next, key depression processing is performed (step S).
43). This is a process of activating a channel to which a sound is assigned in the above process and a sound generation parameter is set to generate a digital tone signal. The generated digital tone signal is transmitted to the D / A converter 1 as described above.
Sound system 1 converted into analog musical tone signal in 8
The musical sound is emitted by being amplified and subjected to predetermined processing in 9 and applied to the speaker 20.

At this time, if the data indicating the tone color corresponding to the voice is set in the tone color buffer, the voice set in the tone color buffer is sounded when the key data 16 is pressed. . After that, the process returns from this keyboard processing routine and returns to the main routine.

On the other hand, if it is determined in step S41 that the event is not the key-on event, it is recognized that the event is the key-off event, and the key release process is performed (step S4).
4). The key release process is a process of searching the channel assigned to the released key and giving predetermined data to the channel to stop the sound generation. After that, the process returns from this keyboard processing routine and returns to the main routine.

In the main routine, other processing is then performed (step S13). In this "other processing", for example, MIDI data transmission / reception processing and the like are performed. Then, the process returns to step S11 and the same process is repeated.

As described above, steps S11 to S13 are performed.
When an event corresponding to a panel operation or a keyboard operation occurs in the process of repeatedly executing, the various functions of the electronic musical instrument are realized by performing a process corresponding to the event.

As described above, according to the first embodiment, the vocal is selected by the tone color selection switch provided on the operation panel 14a, and in this state, the operation panel 1 is selected.
By depressing the tone color sequence switch 140 provided in 4a, the lyrics data is read from the tone color sequence memory 120 and is changed to a tone color of a predetermined voice. By operating the keyboard 16 in this state, a musical tone of a predetermined pitch is generated with the tone color of the changed voice.

By repeating the operation of the tone color sequence switch 14 and the operation of the key data 16 sequentially, a predetermined music can be reproduced in a singing voice. As described above, according to this embodiment, reproduction of a singing voice by an electronic musical instrument can be realized with a simple configuration and a simple operation.

(2) Second Embodiment In the first embodiment, the tone color sequence memory 120 is used.
The timbre sequence switch 140 provided on the operation panel 14 is used as a means for giving a timing (timing to change the timbre) for reading the lyrics data stored in the timbre sequence switch 1.
Instead of 40, a foot switch provided on the pedal 14b may be used.

In this case, if step S23 of the panel processing routine shown in FIG. 5 is changed so as to judge whether or not there is an event of the foot switch, the foot processing is performed by the processing shown in the flow charts of FIGS. It becomes possible to change the voice with the switch. That is, the singing voice can be reproduced by operating the foot switch.

According to the second embodiment, since the timing for changing the voice can be given by using the foot, the degree of freedom in playing the electronic musical instrument is increased, and the singing voice reproducing apparatus which is more convenient is provided. Can be provided.

(3) Third Embodiment Also, the tone color sequence switch 14 of the first embodiment described above.
Instead of 0, a specific key of the keyboard 16 may be used, for example, the lowest note key. Details of the panel processing and the keyboard processing in this case are shown in FIGS. 8 and 9, respectively.
Is shown in the flowchart shown in FIG. The main routine and the tone color sequence change processing routine used in the first embodiment (FIGS. 4 and 6) are used as they are.

In the third embodiment, the tone color sequence changing process is performed by determining whether the tone color sequence switch 140 is pressed when the vocal flag is set in the panel process of the first embodiment. A series of processes such as “do” (steps S23, S24, S25 in FIG. 5) are stopped, and the process corresponding to the above is performed in the keyboard processing routine.

That is, in the panel processing of the third embodiment shown in the flowchart of FIG. 8, first, the presence or absence of a panel event is checked (step S50), and if it is determined that there is no panel event, this Return from the panel processing routine and return to the main routine. On the other hand, when it is determined that there is a panel event, it is checked whether or not the event is a vocal switch event (step S51).

If it is determined that the event is a vocal switch event, then the vocal flag is set to "1" (step S52). This vocal flag is cleared when it is detected in the panel switch process of step S53 that any switch other than the vocal switch in the tone color selection switch is turned on. If it is determined in step S51 that the event is not a vocal switch event, the process of step S52 is skipped.

Then, panel switch processing is performed for other panel switches (step S53). After that, the process returns from this panel processing routine and returns to the main routine.

The processing of steps S50 to S52 is the same as the processing of steps S20 to S22 of the flowchart of FIG. 5 which has already been described in the first embodiment.
Similarly, the processing of step 3 is the same as the processing of step S25, so refer to the description of the relevant portion for details.

In the keyboard processing of the third embodiment shown in the flowchart of FIG. 9, it is first checked whether or not there is a key event (step S60). The determination of the presence / absence of this key event is the same as the processing in step S40 of FIG. 7 which has already been described in the first embodiment, so refer to the description of the relevant portion for details. If it is determined that there is no key event, the process returns to the main routine without performing the following processing and returns to the main routine.

On the other hand, when it is determined that there is a key event, it is checked whether or not the key event is a specific key (for example, the lowest note key) (step S61).
This is done by checking the key number included in the key data stored in the RAM 12 in step S60.

If it is determined that the event is a specific key, then it is checked whether the event is a key-on event (step S62). This is performed by checking the data indicating the event type in the event signal included in the key data stored in the RAM 12 in step S60.

If it is determined that the event is not the key-on event, it is recognized that the event is the key-off event of the specific key, and the following processing is not performed and the keyboard processing routine returns and returns to the main routine. On the other hand, if it is determined that it is a key-on event, then it is checked whether or not the vocal flag is "1", that is, whether or not the vocal switch of the tone color selection switch is in the pressed state (step S63). ). If it is determined that the vocal flag is not "1", that is, the vocal switch of the tone color selection switch is not pressed, the following processing is not performed and the keyboard processing routine is returned to the main routine. .

On the other hand, when it is determined that the vocal flag is "1", that is, the vocal switch of the timbre selection switch is pressed, a timbre sequence changing process is performed (step S64). This tone color sequence changing process is the same as that shown in FIG. After that, the process returns from this keyboard processing routine and returns to the main routine.

If it is determined in the above step S61 that the key is not the specific key, a normal key event process is performed (steps S65 to 69). This processing is the same as the processing in steps S41 to S45 of the flowchart of FIG.

As described above, according to the third embodiment, the timing for changing the voice can be given by using the specific key of the keyboard 16, so that the keyboard 16 can be changed.
It is easy to use for a player who is accustomed to the operation of.

Although the lowest key is used as the specific key in the above embodiment, the present invention is not limited to this. It is possible to use keys that are rarely used during normal performance, such as keys near the lowest pitch and keys near the highest pitch.

Further, in the above embodiment, the tone color is changed when one key is pressed, but the tone color may be changed when a plurality of keys are simultaneously pressed. . For example, the tone color can be changed when two adjacent keys near the lowest or highest tone are pressed. Generally, when two adjacent keys are pressed at the same time, a dissonant sound is produced, and thus the frequency of such a pressing pattern is extremely low. Therefore, according to this configuration, it is possible to instruct to change the tone color without destroying the function of the specific key of the keyboard 16.

(4) Fourth Embodiment In the fourth embodiment, a tone color (voice) is generated when a key of the keyboard 16 is pressed without providing a special instruction means for instructing the read timing of the tone color sequence. With switching, a singing voice with a pitch corresponding to the key is generated.

The panel processing in the fourth embodiment is
The one used in the third embodiment (FIG. 8) is used as it is, and the main routine and the tone color sequence changing processing routine are the same as those used in the first embodiment (FIG. 4 and FIG. 6). It The keyboard processing routine is shown in FIG.
Since the flowchart shown in FIG. 0 is used, only the keyboard processing will be described below.

The keyboard processing in the fourth embodiment is carried out by checking "ON or OFF of the vocal flag and turning it on" between steps S41 and S42 of the keyboard processing routine of the first embodiment shown in FIG. If it is determined that the tone color sequence is changed, the tone color sequence change process is performed ”.

That is, first, it is checked whether or not there is a key event (step S70), and if it is determined that there is no key event, the following processing is not performed and the processing returns from this keyboard processing routine to return to the main routine. Return to.
On the other hand, if it is determined that there is a key event, it is checked whether or not the event is a key-on event (step S71), and if it is determined that it is not a key-on event, key release processing is performed (step S71). S77).
Since the above processing is the same as the processing of steps S40, S41 and S44 in the flowchart of FIG. 7, refer to the description of the relevant part for details.

If it is determined in step S71 that the key-on event has occurred, then it is determined whether or not the vocal flag is "1", that is, whether or not the vocal switch of the tone color selection switch is pressed. It is checked (step S72). Here, the vocal flag is "1"
That is, when it is determined that the vocal switch of the tone color selection switch is pressed, the tone color sequence changing process is performed (step S73). This tone color sequence changing process is the same as that shown in FIG.

On the other hand, if it is determined that the vocal flag is not "1", that is, the vocal switch of the tone color selection switch is not pressed, the process of step S73 is skipped.

Then, the channel allocation process (step S
74), a process of setting the tone generation parameter in the sound source 17 (step S75) and a key depression process (step S76) are sequentially performed, and thereafter, the keyboard processing routine returns to the main routine. Steps S74-76
The processing of step S42 to step S42 in FIG.
Since it is the same as the process of S43, refer to the description of the relevant part for details.

Thus, according to this fourth embodiment,
Since the tone color is changed in synchronization with the key depression of the keyboard 16 and the changed tone color (voice) is used to generate the singing voice of the pitch of the key related to the pressing, the singing voice can be reproduced more easily. There is.

In the first to fourth embodiments, the lyrics data stored in the tone color sequence memory 120 is sequentially read while incrementing the contents of the tone color sequence counter N, but it is sequentially read while decrementing. Of course, it is also possible to adopt a configuration for reading.

A switch for instructing whether to read the lyrics data while incrementing or decrementing the lyrics data may be provided on the operation panel 14, for example, so that the performer can arbitrarily specify. According to this configuration, for example, when the lyrics data is read out too much, the lyrics data can be returned to the original state, which is more convenient.

Further, the operation panel 14 is provided with an LCD display capable of displaying characters, for example, and the tone color sequence memory 120 is provided.
It is also possible to display the content of and to display the lyrics position currently being pronounced with, for example, a cursor. According to this configuration, since the key data 16 can be operated while watching the lyrics, the lyrics can be easily reproduced. In addition, instead of the above LCD display, CR
It is also possible to connect a display device such as a T display device and send the lyrics data to the display device for display.
