The sound source 17 is configured by a well-known waveform memory reading method, and generates musical tone data obtained by synthesizing musical tone according to music data read from the music memory under the control of the CPU 10. The mixer 18 converts the input sound data generated by the microphone section 16 and the musical sound data generated by the sound source 17 into an audio signal and a musical sound signal in an analog signal format, respectively, and then mixes both the signals and amplifies them to a predetermined level. Audio output signal is generated. The sound generator 19 emits the audio output signal supplied from the mixer 18 from the speaker.

(2) Configuration of Song Data Area Next, the configuration of the song data area provided in the song memory 13 will be described with reference to FIGS. As described above, a song data group for karaoke performance is stored in the song data area of the song memory 13. FIG. 2A is a diagram showing the configuration of a song data group KDG stored in the song data area. As shown in this figure, the music data group KDG is composed of music data KD (1) to KD (n) for a plurality of music. One piece of music data KD includes a music data body, pitch error data, timing data, scoring data, and bar position data.

  FIG. 2B is a diagram showing the configuration of the music data body. The song data body represents the time T that represents the event timing with the elapsed time from the start of the performance, the pitch of each tone that makes up the song, note-on (sounding), note-off (mute), melody part and accompaniment An event EVT for identifying a performance part such as a part is formed in a data format called a so-called absolute time system arranged in the order of progression of music, and data END indicating the end of the music is provided at the end. In the typical example shown in FIG. 2B, the beginning of the music data body is time T. However, the present invention is not limited to this example.

The bar position data is composed of B1t (1) to B1t (n) representing the beginning of each bar of the music data body and B2t (1) to B2t (n) representing the rear end. The bar position data B1t (1) to B1t (n) and B2t (1) to B2t (n) are expressed by accumulated timer clock values.

B. Operation Next, the operation of the embodiment according to the above configuration will be described with reference to FIGS. In the following, the operation of the main routine will be described first, and then the timer interrupt (1) to (3) processing in which a timer interrupt is executed will be described. After that, each operation of switch processing, automatic performance processing, and scoring display processing called from the main routine will be described.

(1) Operation of the main routine When the apparatus power is turned on by operating the power switch, the CPU 10 executes the main routine shown in FIG. 5 and proceeds to step SA1, where various registers stored in the work area of the RAM 12 Performs initialization to reset flags and set initial values. In step SA1, the sound source 17 is instructed to initialize various registers and flags. When the initialization is completed, the CPU 10 advances the process to step SA2, and executes a switch processing routine corresponding to the switch event generated by the switch unit 15.

  Next, in step SA3, when the start of the automatic performance is instructed by operating the start / stop switch, the music data body of the selected music data KD (SONG) is read to advance the karaoke performance, or scoring described later. An automatic performance process is performed in which singing practice is repeated from the first bar to the last bar in the display section. Subsequently, in step SA4, for example, a scoring display process for displaying the result of singing practice on the evaluation screen shown in FIG. 21 is executed. In step SA5, for example, the lyrics data corresponding to the song data is subjected to other processing such as displaying captions on the display screen in synchronization with the karaoke performance, and then the processing returns to step SA2. Thereafter, steps SA2 to SA5 are repeated until the apparatus power is turned off.

(2) Operation of Timer Interrupt [1] Process Next, the operation of the timer interrupt [1] process will be described with reference to FIG. The timer interrupt [1] process is interrupted at regular intervals when the interrupt inhibition is canceled. As will be described later, the interruption of the timer interrupt [1] process is canceled when the start of the automatic performance is instructed according to the operation of the start / stop switch in the state where the pitch correction mode is not set. .

  When the interrupt prohibition is canceled and the interrupt execution timing is reached, the CPU 10 advances the processing to step SB1 shown in FIG. 6 and takes the input audio data generated by the microphone unit 16 into the data area of the RAM 12. Subsequently, in steps SB2 to SB3, the pitch of the input audio data taken into the data area of the RAM 12 is extracted, and the extracted pitch is converted into a note number and stored in the register PITCH2.

  In step SB4, a value obtained by subtracting the extracted pitch (note number) stored in the register PITCH2 from the tone pitch (note number of the karaoke performance sound) stored in the register PITCH1 is stored in the register ΔP as a pitch error. In the register PITCH1, note numbers of karaoke performance sounds are stored in step SL21 (see FIG. 18) of automatic performance processing described later.

  In step SB5, the pitch error ΔP calculated in step SB4 is registered as pitch error data ΔP (m) (SONG) in association with the music data KD (SONG) selected in the music memory 13. In step SB5, the timer clock accumulated value t is registered as timing data t (m) (SONG) in association with the music piece data KD (SONG) selected in the music piece memory 13. The pointer m is a value that is incremented every time the timer clock advances in an automatic performance process that will be described later. The pointer SONG is a selected song number selected in a song selection switch process described later. Thereafter, the process proceeds to step SB6, where the input audio data taken into the data area of the RAM 12 is read out and supplied to the mixer 18 to complete the present process.

  As described above, when the automatic performance is started in response to the start / stop switch operation in a state where the pitch correction mode is not set, the CPU 10 interrupts and executes the timer interrupt [1] process at a certain period, and the selected music number. The pitch error data ΔP (m) (SONG) and timing data t (m) (SONG) in the song data KD (SONG) specified by SONG are generated and registered in the song data area of the song memory 13, while the microphone The input audio data generated by the unit 16 is supplied to the mixer 18.

(3) Operation of Timer Interrupt [2] Process Next, the operation of the timer interrupt [2] process will be described with reference to FIG. In the timer interrupt [2] process, as will be described later, pitch error data ΔP (m) (SONG) exists in the music data KD (SONG) specified by the selected music number SONG, and the pitch correction mode is set. In the state, the timer interrupt prohibition is canceled when the start of the automatic performance is instructed according to the start / stop switch operation.

  When the interrupt prohibition is canceled and the interrupt execution timing is reached, the CPU 10 advances the processing to step SC1 shown in FIG. 7 and takes the input voice data (singing voice) generated by the microphone unit 16 into the data area of the RAM 12. Next, in step SC2, the data area of the RAM 12 according to the pitch error data ΔP (t) (SONG) specified by the timer clock accumulated value t from the music data KD (SONG) specified by the selected song number SONG. Convert the pitch of the input audio data stored in. That is, by adding the pitch error data ΔP (t) (SONG) to the pitch extracted from the input voice data, the pitch of the input voice data is corrected to the pronunciation pitch of the music data body. In step SC3, the input voice data subjected to the pitch conversion (pitch correction) in step SC2 is supplied to the mixer 18 and the process is completed.

  As described above, when the pitch error data ΔP (t) (SONG) exists in the song data KD (SONG) specified by the selected song number SONG and the pitch correction mode is set, the start / stop switch When the automatic karaoke performance is started in accordance with the operation, the CPU 10 interrupts and executes the timer interrupt [2] process at regular intervals, and the pitch error data specified by the timer clock accumulated value t from the music data KD (SONG). The pitch of the input audio data is corrected according to ΔP (t) (SONG) and supplied to the mixer 18.

(4) Operation of Timer Interrupt [3] Process Next, the operation of the timer interrupt [3] process will be described with reference to FIG. In the timer interrupt [3] process, as described later, in the state where the scoring display mode is set, when the start of automatic performance is instructed according to the start / stop switch operation, the timer interrupt prohibition is canceled.

  When the interrupt prohibition is canceled and the interrupt execution timing is reached, the CPU 10 advances the process to step SD1 illustrated in FIG. 8 and takes in the input audio data generated by the microphone unit 16 into the data area of the RAM 12. Next, in step SD2, the captured input audio data is supplied to the mixer 18 and the process is terminated.

(5) Operation of Switch Processing Next, the operation of switch processing will be described with reference to FIG. When this process is executed through step SA2 (see FIG. 5) of the main routine described above, the CPU 10 proceeds to step SE1 shown in FIG. 9 and selects a song to be played karaoke according to the operation of the song selection switch. Perform song selection switch processing. Subsequently, in step SE2, pitch correction mode switch processing for setting or canceling the pitch correction mode according to the operation of the pitch correction mode switch is executed.

  In step SE3, start / stop switch processing for instructing the start or end of automatic performance (karaoke performance) is executed in accordance with the operation of the start / stop switch. Next, in step SE4, in accordance with the operation of the scoring display switch, a scoring display switch process for displaying the singing scoring result on the screen or deleting the screen is executed. Thereafter, the process proceeds to step SE5, and a scoring display changeover switch process for setting or canceling the scoring display mode according to the operation of the scoring display changeover switch is executed.

(6) Music Selection Switch Process Operation FIG. 10 is a flowchart showing the music selection switch process operation. When this processing is executed through the above-described switch processing step SE1 (see FIG. 9), the CPU 10 proceeds to step SF1 shown in FIG. 10, and the start flag STF is “0”, that is, automatic performance (karaoke performance). It is determined whether or not it is stopped. Note that the start flag STF indicating whether or not the automatic performance is stopped is set by a start / stop switch process (see FIG. 12) described later.

  If the automatic performance is in progress and the start flag STF is set to “1”, the determination result in step SF1 is “NO”, and this process is completed. Therefore, the music selection switch operation is invalidated during karaoke performance. On the other hand, if the start flag STF is “0”, that is, if the automatic performance is stopped, the determination result in step SF1 is “YES”, and the process proceeds to step SF2. In step SF2, it is determined whether or not the music selection switch is turned on. If the song selection switch is not turned on, the determination result is “NO”, and this process is completed.

  On the other hand, when the music selection switch is turned on, the determination result is “YES”, and the flow proceeds to Step SF3. In step SF3, the music number corresponding to the music selection switch that has been turned on is stored in the register SONG. In other words, in this embodiment, there are a plurality of song selection switches assigned to each song, and the song number associated with the song selection switch that is turned on among these is the selected song number SONG.

(7) Operation of Pitch Correction Mode Switch Process FIG. 11 is a flowchart showing the operation of the pitch correction mode switch process. When this processing is executed through the above-described switch processing step SE2 (see FIG. 9), the CPU 10 proceeds to step SG1 shown in FIG. 11, and the start flag STF is “0”, that is, automatic performance (karaoke performance). It is determined whether or not it is stopped. If the automatic performance is in progress (the start flag STF is “1”), the determination result is “NO” and the process is completed. Therefore, the pitch correction mode switch operation is invalidated during the automatic performance.

  On the other hand, if the automatic performance is stopped, the determination result in step SG1 is “YES”, and the process proceeds to step SG2. In step SG2, it is determined whether or not the pitch correction mode switch is turned on. If the pitch correction mode switch is not turned on, the determination result is “NO”, and this process is completed.

  On the other hand, when the pitch correction mode switch is turned on, the determination result in step SG2 is “YES”, and the process proceeds to step SG3. In step SG3, the correction mode flag HF is inverted. Next, in step SG4, it is determined whether or not the inverted correction mode flag HF is “1”.

  Since the pitch correction mode switch is a toggle switch that instructs the alternate to set or cancel the mode each time it is turned on, in step SG4, whether or not the pitch correction mode is set according to the on operation of the pitch correction mode switch. Deciding. When the inverted correction mode flag HF is “0”, that is, when the pitch correction mode is canceled, the determination result here is “NO”, and this processing is completed.

  On the other hand, when the inverted correction mode flag HF is “1”, that is, when the pitch correction mode is set, the determination result in Step SG4 becomes “YES”, and the process proceeds to Step SG5. In step SG5, it is determined whether or not pitch error data ΔP () (SONG) is registered in the music data KD (SONG) designated by the selected music number SONG. If the pitch error data ΔP () (SONG) is registered, the determination result is “YES”, and the present process ends. On the other hand, if the pitch error data ΔP () (SONG) is not registered, the determination result is “NO”, and the flow advances to step SG6. In step SG6, the correction mode flag HF is reset to zero and the process is terminated.

  As described above, in the pitch correction mode switch processing, when the pitch error data ΔP () (SONG) is not registered in the song data KD (SONG) designated by the selected song number SONG, the automatic performance is stopped. Even if the pitch correction mode switch is turned on, the pitch correction mode is not set, and the pitch correction mode can be set when the pitch error data ΔP () (SONG) is registered.

(8) Start / Stop Switch Processing Operation Next, the start / stop switch processing operation will be described with reference to FIGS. When this process is executed through the above-described switch process step SE3 (see FIG. 9), the CPU 10 proceeds to step SH1 shown in FIG. 12, and determines whether or not the start / stop switch is turned on. Note that, as will be described later, the start / stop switch is a toggle switch that instructs the alternate to start or stop each time it is turned on. If the start / stop switch is not turned on, the determination result in step SH1 is “NO”, and the present process ends without performing anything.

  On the other hand, when the start / stop switch is turned on, the determination result in step SH1 is “YES”, the process proceeds to step SH2, and the start flag STF is inverted. Subsequently, in step SH3, it is determined whether or not the inverted start flag STF is “1”, that is, whether or not the start of automatic performance (karaoke performance) is instructed. If the inverted start flag STF is “0”, the determination result is “NO”, and the process proceeds to step SH4. In step SH4, the sound source 17 is instructed to mute as the automatic performance is stopped, and in the subsequent step SH5, interrupt execution of the timer interrupt process being executed is prohibited and the process is terminated.

  On the other hand, when the inverted start flag STF becomes “1” and is set to a state instructing the start of automatic performance, the determination result in step SH3 becomes “YES”, and the process proceeds to step SH6. In step SH6, it is determined whether the scoring display flag SF is “0”, that is, the scoring display mode is not set. Note that the scoring display mode refers to a processing operation in which a user's song is evaluated and displayed on the screen as described later. Hereinafter, the description of the operation will be made separately for the case where the scoring display mode is not set and the case where the scoring display mode is set.

<When the scoring display mode is not set>
If the scoring display mode is not set, the scoring display flag SF is “0”, so that the determination result in step SH6 is “YES”, and the process proceeds to step SH7. In step SH7, the initial address (head address) of the music data body included in the music data KD (SONG) corresponding to the selected music number SONG is stored in the register AD. Hereinafter, the contents of the register AD are referred to as a read address AD. Next, in step SH8, the music data body is read from the music data KD (SONG) designated by the selected music number SONG in the music memory 13 in accordance with the read address AD.

  Subsequently, in step SH9, it is determined whether the read music data body is time T or event EVT. As shown in FIG. 2B, the time T is normally stored at the head address. For example, an event EVT that specifies the tone color of the generated musical tone prior to the karaoke performance may be stored at the head address. is there. Accordingly, when the time T is read from the head address, the process proceeds to step SH10 and the time T is stored in the register T.

  Subsequently, in step SH11, the counter t for accumulating the timer clock is reset to zero. The value of the counter t is referred to as a timer clock accumulated value t. In step SH12, it is determined whether the correction mode flag HF is “0”, that is, whether the pitch correction mode is set. If the pitch correction mode is not set, the determination result is “YES”, and the flow proceeds to step SH13. In step SH13, the prohibition of the timer interrupt [1] process described above is canceled, and the initial value “1” is set in the pointer m, and this process ends.

  As a result, the CPU 10 starts interrupt execution of the timer interrupt [1] process described above at regular intervals. Then, the pitch error data ΔP (m) (SONG) and the timing data t (m) (SONG) in the music data KD (SONG) specified by the selected music number SONG are generated, and the music data KD in the music memory 13 is generated. The input audio data generated by the microphone unit 16 is supplied to the mixer 18 while being registered in association with (SONG).

  On the other hand, if the pitch correction mode is set by operating the pitch correction mode switch, the determination result in step SH12 is “NO”, and the process proceeds to step SH14, where the prohibition of the timer interrupt [2] process is canceled. And this processing is finished. As a result, the CPU 10 starts interrupt execution of the timer interrupt [2] process described above at regular intervals. Then, from the music data KD (SONG) specified by the selected music number SONG, the input audio data is changed according to the timer clock accumulated value t and the pitch error data ΔP (t) (SONG) specified by the selected music number SONG. The pitch is corrected and supplied to the mixer 18.

  On the other hand, when the event EVT is read from the head address of the music data body, the process proceeds to step SH15 via step SH9 described above, and the read event EVT is sent to the sound source 17. Accordingly, the sound source 17 is set to generate a musical tone having a tone color designated by the event EVT when the event EVT sent from the CPU 10 is an event for which the tone color is set, for example. In step SH16, the read address AD is incremented, and the process returns to step SH8 described above. Thereafter, until the time T is read, the event EVT is sequentially read according to the incremented address AD and sent to the sound source 17. Then, when the time T is read in accordance with the incremented address AD, the processing of steps SH10 to SH14 described above is executed, and this processing is finished.

<When set to scoring display mode>
If the scoring display mode is set, since the scoring display flag SF is “1”, the determination result in step SH6 is “NO”, and the CPU 10 advances the process to step SH17 shown in FIG. In step SH17, the bar position data B1t (n) (SONG) and B2t (n) (SONG) in the music data KD (SONG) specified by the selected music number SONG are read.

  As will be described later, the pointer n for designating the bar position becomes “1” when the scoring display switch is turned on, and is further incremented according to the number of times the scoring display switch is turned on. Therefore, the bar position data B1t (n) (SONG) represents the bar position at the beginning of the scoring display section, while the bar position data B2t (n) (SONG) represents the bar position at the end of the scoring display section. .

  Next, in step SH18, the initial address (head address) of the music data body included in the music data KD (SONG) designated by the selected music number SONG is stored in the register AD. In step SH19, the music data body is read from the music data KD (SONG) according to the read address AD. Subsequently, in step SH20, it is determined whether the read music data body is time T or event EVT.

  When the event EVT is read from the head address, the process proceeds to step SH21, the read address AD is incremented, and the process returns to the above-described step SH19. Thereafter, steps SH19 to SH21 are repeated until the time T is read, and the read address AD is incremented. When the time T is read in accordance with the incremented address AD, the process proceeds to step SH22, and the time T is stored in the register T. Next, in step SH23, it is determined whether or not the read time T exceeds the bar position data B1t (n) (SONG), that is, whether or not the bar at the beginning of the scoring display section has been reached.

  If the time T has not reached the starting bar of the scoring display section, the determination result is “NO”, the process returns to the above-described step SH21, the read address AD is incremented, and then the above-described step SH19 again. Return processing to. Then, it is assumed that the time T read out in accordance with the read-out read address AD reaches the bar at the beginning of the scoring display section. If it does so, the judgment result of the said step SH23 will be "YES", and will progress to step SH24.

  Thus, in steps SH19 to SH23, the read address AD is incremented in order to find the time T to reach the bar position at the beginning of the scoring display section. When the time T reaching the bar position at the beginning of the scoring display section is found, the process proceeds to step SH24, and the time T is stored in the register t. Thereafter, the process proceeds to step SH25 to instruct start of timer counting. As a result, the CPU 10 generates a timer clock by executing a timer count process (not shown). The timer count process is a process for generating a timer clock corresponding to the performance tempo of a song by a timer interrupt.

  Next, in step SH26, the prohibition of the timer interrupt [3] process described above is canceled and the process ends. As a result, the CPU 10 starts interrupt execution of the timer interrupt [3] process described above at regular intervals. Then, the input voice data generated by the microphone unit 16 is taken into the data area of the RAM 12 and the taken input voice data is supplied to the mixer 18.

(9) Operation of scoring display switch processing Next, the operation of scoring display switch processing will be described with reference to FIG. When this processing is executed through the above-described switch processing step SE4 (see FIG. 9), the CPU 10 proceeds to step SJ1 shown in FIG. 14 and determines whether or not the scoring display switch is turned on. If the scoring display switch is not turned on, the determination result is “NO”, and the process ends without performing anything.

  On the other hand, when the scoring display switch is turned on, the determination result in step SJ1 is “YES”, and the process proceeds to step SJ2. In step SJ2, it is determined whether or not the scoring display flag SF is “0”, that is, the scoring display mode is not set. If the scoring display flag SF is set to “1” and the scoring display mode is set, the determination result is “NO”, the process proceeds to step SJ3, and after the scoring display flag SF is reset to zero, the subsequent step In SJ4, the evaluation screen (to be described later) is erased and the present process is terminated.

  On the other hand, if the scoring display mode is not set, the determination result of step SJ2 is “YES”, and the process proceeds to step SJ5. In step SJ5, it is determined whether or not scoring data (see FIG. 4A) is registered in the music data KD (SONG) designated by the selected music number SONG. If the scoring data is not registered in the music data KD (SONG), the scoring state is unscored, so the determination result is “NO” and the process is completed.

  On the other hand, if the scoring data is registered in the song data KD (SONG), the determination result in step SJ5 is “YES”, and the process proceeds to step SJ6. In step SJ6, the scoring display flag SF is set to “1” to set the scoring display mode, and the flag CF is set to “1”. Next, in step SJ7, “1” is set in the pointer n, and this processing is completed.

(10) Operation of scoring display changeover switch process Next, the operation of the scoring display changeover switch process will be described with reference to FIG. When this process is executed via the above-described switch process step SE5 (see FIG. 9), the CPU 10 proceeds to step SK1 shown in FIG. 15 and determines whether or not the scoring display changeover switch is turned on. If the scoring display changeover switch is not turned on, the determination result is “NO”, and the present process ends without performing anything.

  On the other hand, when the scoring display changeover switch is turned on, the determination result in step SK1 is “YES”, and the process proceeds to step SK2. In step SK2, it is determined whether the scoring display flag SF is “1”, that is, whether the scoring display mode is set. If it is not set to the scoring display mode, the determination result is “NO”, and the present process is terminated. If the scoring display mode is set, the determination result is “YES”, and the process proceeds to step SK3. In step SK3, the process is completed after the pointer n is incremented.

(11) Operation of Automatic Performance Processing Next, the operation of automatic performance processing will be described with reference to FIGS. When this process is executed via step SA3 (see FIG. 5) of the main routine described above, the CPU 10 advances the process to step SL1 shown in FIG. In step SL1, it is determined whether the start flag STF is “1”, that is, whether automatic performance is in progress. If the automatic performance is stopped, the determination result is “NO”, and the present process ends.

  On the other hand, if the automatic performance is in progress, the determination result in step SL1 is “YES”, and the flow proceeds to step SL2. In step SL2, it is determined whether the minimum unit time has elapsed. The minimum unit time refers to the time for one cycle of the timer clock. If the minimum unit time has not elapsed, the determination result here is “NO”, and this processing is once completed. If the minimum unit time has elapsed, the determination result is “YES”, and the step Proceed to SL3. In step SL3, the timer clock accumulated value t is incremented while the pointer m is incremented. The pointer m designates pitch error data ΔP (m) (SONG) and timing data t (m) (SONG) in the song data KD (SONG) designated by the selected song number SONG.

  Subsequently, in step SL4, it is determined whether or not the time T stored in the register T matches the timer clock accumulated value t, that is, whether or not the event timing has been reached. If the event timing has not been reached, the determination result is “NO”, and this processing is once completed. On the other hand, when the event timing is reached, the determination result is “YES”, the process proceeds to step SL5, and the read address AD of the music data body is incremented. Thereafter, the process proceeds to step SL6 shown in FIG. 17, and it is determined whether or not the scoring display flag SF is “1”, that is, the scoring display mode is set. Hereinafter, the operation description will be divided into a case where the scoring display mode is not set and a case where it is set.

<When the scoring display mode is not set>
If it is not set to the scoring display mode, the judgment result in step SL6 is “NO”, the process proceeds to step SL15 shown in FIG. 18, and the song data in the song data KD (SONG) designated by the selected song number SONG is displayed. The main body is read according to the read address AD. Next, in step SL16, it is determined whether the read music data body is “time T”, “event EVT”, or “data END”. Hereinafter, the operation will be described separately for each case where the read music data body is “time T”, “event EVT”, and “data END”.

a. In case of “Time T”
If the read music data body is “time T”, the process proceeds to step SL17, where it is stored in the register T, and the process is temporarily terminated.

b. In the case of “Event EVT”
If the read music data body is “event EVT”, the process proceeds to step SL18 to determine whether the “event EVT” is a melody part event. If “event EVT” is an accompaniment part event, the determination result is “NO”, the process proceeds to step SL19, the event of the accompaniment part is sent to the sound source 17, and the process proceeds to the above-described step SL5 (see FIG. 16). return. As a result, the sound source 17 generates a karaoke performance sound (accompaniment sound).

  On the other hand, if “event EVT” is a melody part event, the determination result in step SL18 is “YES”, and the flow proceeds to step SL20. In step SL20, it is determined whether or not “event EVT” of the melody part is a note-on event instructing pronunciation. If it is a note-on event, the determination result is “YES”, and the process proceeds to step SL21. After the note number (sounding pitch) included in the note-on event is stored in the register PITCH1, the above-described step SL5 (see FIG. 16). )

  On the other hand, if the “event EVT” of the melody part is a note-off event instructing mute, the determination result in step SL20 is “NO”, the process proceeds to step SL22, and the contents of the register PITCH1 are cleared. The process returns to step SL5 (see FIG. 16).

c. For “Data END”
If the read music data body is “data END”, the process proceeds to step SL23 to instruct the sound source 17 to mute. In step SL24, the execution of the timer interrupt [1] process described above is prohibited. Thereafter, the process proceeds to step SL25, where the start flag STF is set to “0” and the automatic performance is stopped. Next, in step SL26, a scoring process (described later) for evaluating the content of the user's singing performed in accordance with the karaoke performance is executed, and this process is finished.

  As described above, when the scoring display mode is not set, every time the timer clock accumulated value t coincides with the time T, the tune data body is read out according to the read-out read address AD and the karaoke performance is performed. Make it progress. That is, if the read music data body is time T, it is stored in the register T as the next event timing. If the read music data body is an accompaniment part event, it is sent to the sound source 17 for karaoke performance.

  Further, if the read tune data body is a note-on event of the melody part, the note number included in the note-on event is stored in the register PITCH1 in order to calculate the difference from the pitch of the user's singing voice, If it is a note-off event, the register PITCH1 is cleared. If the read song data body is data END, the sound source 17 is muted to stop the automatic performance (karaoke performance) and a scoring process (to be described later) for evaluating the contents of the user's singing performed according to the karaoke performance. ).

<When set to scoring display mode>
If the scoring display mode is set, the determination result in step SL6 shown in FIG. 17 is “YES”, and the process proceeds to the next step SL7. In step SL7, it is determined whether or not the current time T exceeds the bar position data B2t (n) (SONG), that is, whether or not the bar at the end of the scoring display section has been reached. If the current time T has not reached the measure at the end of the scoring display section, the determination result is “NO”, and the case where the scoring display mode is not set after step SL15 (see FIG. 18) described above. Perform the action.

  On the other hand, if the current time T has reached the measure at the end of the scoring display section, the determination result in step SL7 is “YES”, and the flow proceeds to step SL8. In step SL8, the initial address (head address) of the music data body included in the music data KD (SONG) designated by the selected music number SONG is stored in the register AD. Subsequently, in step SL9, the music data body is read from the music data KD (SONG) in accordance with the read address AD stored in the register AD. In step SL10, it is determined whether the read music data body is time T or event EVT.

  When the event EVT is read from the head address, the process proceeds to the next step SL11, the read address AD is incremented, and the process returns to the above-described step SL9. Thereafter, until the time T is read, steps SL9 to SL11 are repeated to increment the read address AD. When the time T is read according to the read address AD that has been incremented, the process proceeds to step SL12, where the time T is stored in the register T. Next, in step SL13, it is determined whether or not the read time T exceeds the bar position data B1t (n) (SONG), that is, whether or not the bar at the beginning of the scoring display section has been reached.

  If the time T has not reached the starting bar of the scoring display section, the determination result is “NO”, the process returns to the above-described step SL11, the read address AD is incremented, and then the above-mentioned step SL9 again. Return processing to. Then, it is assumed that the time T read out in accordance with the read-out read address AD reaches the bar at the beginning of the scoring display section. If it does so, the judgment result of the said step SL13 will be "YES", and will progress to step SL14.

  Thus, in steps SL9 to SL13, the read address AD is incremented in order to find the time T to reach the bar position at the beginning of the scoring display section. When the time T reaching the bar position at the beginning of the scoring display section is found, the process proceeds to step SL14, where the time T is stored in the register t. Then, the operation | movement when not set to the scoring display mode after step SL15 (refer FIG. 18) mentioned above is performed.

  As described above, when the scoring display mode is set, whether or not the current time T has reached the end of the scoring display section every time the timer clock accumulated value t matches the time T When the bar at the end of the scoring display section is reached, after returning to the time T corresponding to the bar at the beginning of the scoring display section, the operation when the scoring display mode is not set is executed. Therefore, when the scoring display mode is set, the karaoke performance is repeated from the first bar to the last bar of the scoring display interval until the stop of the automatic performance is instructed by operating the start / stop switch. Yes.

(12) Operation of scoring process Next, the operation of the scoring process will be described with reference to FIG. When this process is executed through step SL26 of the automatic performance process described above, the CPU 10 proceeds to step SM1 shown in FIG. 19, sets "1" to the pointer n, and resets the pointer m to zero. Subsequently, in step SM2, the registers L and S are reset to zero. Next, in step SM3, “0” is set to the bar position data B1t (n) (SONG) specified by the pointer n in the music data KD (SONG) specified by the selected music number SONG.

  In step SM4, pitch error data ΔP (m) (SONG) and timing data t (m) (SONG) specified by the pointer m are read from the music data KD (SONG) specified by the selected song number SONG. . Next, at step SM5, the presence / absence of the data read at step SM4 is determined. That is, if there is pitch error data ΔP (m) (SONG) or timing data t (m) (SONG)) to be read, the determination result is “YES”, and the flow proceeds to step SM6.

  In step SM6, it is determined whether or not the timing data t (m) (SONG) is smaller than the bar determination value. The measure determination value is a value obtained by multiplying the number of timer clocks for one measure by the value of the pointer n. Therefore, in this step SM6, it is determined whether or not the reading of the pitch error data ΔP (m) (SONG) for one measure has been completed. When the timing data t (m) (SONG) is smaller than the bar determination value and the pitch error data ΔP (m) (SONG) for one bar has not been read, the determination result is “YES”. Proceed to step SM7. Next, in step SM7, the pitch error data ΔP (m) (SONG) is added to the register S.

  Subsequently, in step SM8, the value of the register L is incremented and stepped. Note that the value of the register L to be incremented corresponds to the number of notes (number of note-on events) included in the measure specified by the pointer n. Next, in step SM9, after the pointer m is incremented, the process returns to step SM4 described above. Thereafter, steps SM4 to SM9 are repeated until the reading of pitch error data ΔP (m) (SONG) for one measure is completed. As a result, the total number of notes included in the measure specified by the pointer n is accumulated in the register L, and the corresponding accumulated value of the pitch error data ΔP (m) (SONG) is stored in the register S.

  When the pitch error data ΔP (m) (SONG) for one bar is read and the timing data t (m) (SONG) becomes larger than the bar determination value, the determination result in step SM6 is “NO”. Proceed to SM10. In step SM10, the pitch error average obtained by dividing the accumulated value of the pitch error data ΔP (m) (SONG) stored in the register S by the total number of notes stored in the register L is designated by the selected song number SONG. Is registered in the scoring data S (n) (SONG) of the measure designated by the pointer n in the music data KD (SONG) to be performed.

  Thus, when the scoring data S (n) (SONG) of the bar designated by the pointer n is registered in the music piece data KD (SONG), the process proceeds to step SM11, and the bar position indicating the end of the bar designated by the pointer n is reached. A bar determination value obtained by multiplying the number of timer clocks for one bar by the value of the pointer n is registered in the data B2t (n) (SONG). Next, in step SM12, the same bar determination value as in step SM11 is registered in the bar position data B2t (n + 1) (SONG) indicating the start of the next bar. In step SM13, after the pointer n is incremented, the process returns to step SM2 described above to proceed with the creation of scoring data for the next bar.

  Thereafter, the above-described process is performed until the pitch error data ΔP (m) (SONG) and the timing data t (m) (SONG) are completely read from the music data KD (SONG) designated by the selected song number SONG. By repeating, scoring data S (n) (SONG) for each measure is registered, and measure position data B1t (n) (SONG) and B2t (n) (representing the start and end of the corresponding measure section) SONG) is registered. When the pitch error data ΔP (m) (SONG) and the timing data t (m) (SONG) are all read, the determination result in step SM5 is “NO”, and this process is completed. .

(13) Operation of scoring display processing Next, the operation of scoring display processing will be described with reference to FIG. When this process is executed through step SA4 (see FIG. 5) of the main routine described above, the CPU 10 advances the process to step SN1 shown in FIG. In step SN1, it is determined whether or not the scoring display flag SF is “1”, that is, in the scoring display mode. If the scoring display mode is not set, the determination result is “NO”, and the present process is terminated without performing anything.

  On the other hand, if it is under the scoring display mode, the determination result is “YES”, the process proceeds to step SN2, and it is determined whether or not the flag CF is “1”. When the flag CF is “1”, when the singing practice is performed based on the song data KD (SONG) in which the scoring data (see FIG. 4A) is registered, the scoring display switch is turned on to display the scoring. Indicates the state set to mode. If it is not in such a state, the determination result in step SN2 is “NO”, and the present process is terminated without performing anything. If it is in this state, the determination result is “YES” and the process proceeds to step SN3.

  In step SN3, the score data S (m) (SONG) with the nth lowest evaluation is searched for in the song data KD (SONG) designated by the selected song number SONG. Next, in step SN4, based on the search result in step SN3, for example, an example evaluation screen illustrated in FIG. 21 is formed and output to the video encoder. In step SN5, the flag CF is reset to zero and the process is terminated.

  As described above, in the present embodiment, when the music data KD (SONG) is designated to start the automatic performance (karaoke performance), the prohibition of the timer interrupt [1] process is canceled. As a result, the automatic performance process sequentially reproduces the song data body in the song data KD (SONG) to advance the karaoke performance, while the timer interrupt [1] process sings along with the karaoke performance. And pitch error data ΔP (m) (SONG) representing the difference between the tone data and the pronunciation pitch of the song data main body, and timing data t (m) (SONG) representing the progress position are generated in the song data KD (SONG). sign up.

  Thus, after the timing data t (m) (SONG) and the pitch error data ΔP (m) (SONG) are registered in the music data KD (SONG) as a history, the pitch correction mode switch is operated by the operation of the pitch correction mode switch. When the start of automatic performance (karaoke performance) is instructed after setting to, the prohibition of timer interrupt [2] processing is canceled. As a result, the automatic performance processing sequentially reproduces the music data body in the music data KD (SONG) and advances the karaoke performance, while the timer interrupt [2] processing accumulates the timer clock from the music data KD (SONG). In accordance with the pitch error data ΔP (t) (SONG) specified by the value t, the user's singing voice sung in accordance with the karaoke performance is pitch-corrected and supplied to the mixer 18, so at the place where the skillful singing was not It becomes possible to automatically correct the user's singing voice to a correct pitch as exemplified.

  In this embodiment, when the timing data t (m) (SONG) and the pitch error data ΔP (m) (SONG) are already registered in the selected music data KD (SONG), the scoring is performed by operating the scoring display switch. When the display mode is set and the automatic performance is started by specifying the bar position at the beginning of the scoring display section and the bar position at the end of the scoring display section according to the number of times the scoring display changeover switch is turned on. The designated grading display section can be automatically and repeatedly played with karaoke.

  Further, in the present embodiment, when the music data body of the selected music data KD (SONG) is automatically played from the beginning to the end, the scoring process is performed with the pitch error data ΔP (m) (SONG) and the timing data t (m ) (SONG) and scoring data S (n) (SONG) for each bar, and bar position data B1t (n) (SONG) and B2t (n) (SONG) indicating the start and end of the corresponding bar section ) Is registered in the song data body. When the scoring display switch is subsequently set to the scoring display mode, the scoring result of the bar specified by the scoring display switching switch operation can be displayed on the screen.

  In the above-described embodiment, while the automatic performance (karaoke performance) is in progress, the operation of the pitch correction mode switch is disabled and the pitch correction mode can be set only before the automatic performance is started. It is possible to set the pitch correction mode in accordance with the pitch correction mode switch operation while the automatic performance is in progress. In such an aspect, when the pitch correction mode is set during the automatic performance, the timer interrupt [2] process (see FIG. 7) described above is activated. If it does in this way, it will become possible to correct a user's singing voice to the correct pitch according to a model in the part which a user specifies.
