FIG. 2 is a view showing an example of the microphone 3, in which the trigger switch 2 is attached to the handshake.

First, the outline of the operation of the music reproducing apparatus configured as described above will be described with reference to FIGS.

FIG. 3 shows an example of a song performed by a singer, for example,
Fig. 4 shows a part of the musical score of "Ellie My Love".
An example of the format of the data stored in the music data memory 1 is shown, (a) shows the lyrics data stored in the lyrics data memory, and (b) shows the performance data stored in the performance data memory. ing. Further, FIG. 5 shows a display example of lyrics by the display device 10. In FIG. 4A and FIG. 5, "|" represents a "breakpoint".

As shown in FIG. 3, "d", "my",
A break point is set in advance at the position of “so”, and “‖” and “breakpoint” are stored at the position where the break point is set, respectively, as shown in FIGS. 4 (a) and 4 (b). ing. Also, "T" in (a)
“IMING 1” indicates the timing of displaying lyrics for a predetermined measure at a time, as shown by “‖Erie‖ ...”, and “TIMING 2” in (b) indicates the timing of outputting performance data. , In addition, in order to display the lyrics before the accompaniment of the music begins, "TIM
ING 1 ”is set to a value smaller than“ TIMING 2 ”.

The CPU 6 performs processing in accordance with the processing program of the program memory 8, and when the break point is read from the performance data memory, the reproduction of the music is temporarily stopped until the trigger switch 2 is pressed. When the temporary stop release input is made by the trigger switch 2, the CPU 6
Resumes playing the song.

Next, the processing operations executed by the CPU 6 will be described with reference to FIG.
~ It will be described in detail based on the flowchart shown in FIG.

FIG. 6 is a flow chart of the main routine of this embodiment. In step S1, various parameters are initialized, and in step S2, a start / stop switch (not shown) is pressed (on event). Or not. When the button is pressed, the process proceeds to step S3, and a flag indicating whether or not music reproduction is being performed (hereinafter referred to as "RUN flag") is inverted. here,
The RUN flag indicates that the music is being reproduced when the value is "1", and is ended when the value is "0".

In a succeeding step S4, it is determined whether or not the RUN flag is "1". When the RUN flag is "1", the number of the selected song is stored in the working memory 7 (hereinafter referred to as "SN").
G ”), and pointers are set (reset) to the respective leading addresses of the lyrics data memory and the performance data memory of the music to be reproduced. Here, the pointer is a pointer indicating the contents stored in the lyrics data memory (hereinafter referred to as "lyric data pointer") and a pointer indicating the contents stored in the performance data memory (hereinafter referred to as "performance data pointer"). 2 pointers are shown.

On the other hand, when the RUN flag is "0",
The CPU 6 outputs a mute signal (mute request code) to the tone generator 9, and stops the tone signal output of the tone generator 9.

Next, in step S7, it is determined whether or not a music selection switch (not shown) is pressed. If it is pressed, the process proceeds to step S8, and the selected music number is stored in the memory SNG.
And set to step S9. When the music selection switch is not pressed, step S8 is skipped and step S8 is performed.
Proceed to 9.

In step S9, the trigger switch 2
It is determined whether or not is pressed, and when it is pressed, the value of the RUN flag is determined in step S10, and the value is "1".
, That is, when the music reproducing device is in the reproducing operation,
In step S11, the program counter TIME is reset and the process proceeds to step S12. If the trigger switch 2 is not pressed in step S9 or if the value of the RUN flag is "0" in step S10, step S12
Proceed to. In step S12, after performing other processing, for example, processing such as tempo adjustment, the processing returns to step S2 and the above-described processing is repeated.

7 and 8 are flow charts showing the details of the processing of the timer interrupt routine which is a feature of the present invention.

The timer interrupt request of this embodiment is configured to be issued once every 96 minutes by the timer 12. That is, when the timer 12 measures the time corresponding to the length of 96 minutes, it outputs an interrupt request to the CPU 6, and when the CPU 6 receives this interrupt request, the CPU 6 shifts the processing from the main routine to the interrupt routine. Since the time corresponding to this 96 minute length changes according to the change in tempo, the time interval at which an interrupt request is made changes depending on the tempo.

First, in step S21 of FIG. 7, it is determined whether or not the RUN flag is "1". If it is not "1", the interrupt process is terminated, and if it is "1", step S22.
Then, the counter TIME is incremented by 1.

In the following step S23, the performance data at the position indicated by the performance data pointer is read from the performance data memory, and in step S24 it is determined whether or not the code of the performance data is an end code. If the result of the determination is that it is an end code, the flow proceeds to step S25, the RUN flag is set to "0" to end the performance, and then the interrupt processing ends. On the other hand, if the code is not the end code, the process proceeds to step S26 to determine whether or not the code is a break code.
In step S27, it is determined whether or not the value of the timing counter (program counter) matches the set reproduction timing. If they match, step S
After proceeding to step 28 to execute processing for reproducing musical tones such as key events and key codes, the performance data pointer is advanced to the position of the next performance data in step S29 and step S29 is executed.
Return to 23. That is, as described above, the performance data in the performance data memory (for example, "key-on" in FIG. 4B,
Before "D5", the reproduction timing (for example, "TIMI in FIG. 4B") indicating the output timing of the performance data is output.
NG 2 ″) is stored, and the performance data is output when the value of the timing counter, which is an up counter, is compared with the value of the reproduction timing.

On the other hand, if the chord of the performance data is a break chord in step S26, the flow advances to step S30 to determine whether or not the value of the counter TIME is "12" or less, and if the value is "12" or less. If there is, the process proceeds to step S31, the value of the reproduction timing (for example, TIMING 2 in FIG. 4B) is set in the timing counter, and the process proceeds to step S29. Here, the reason why the reproduction timing value is set in the timing counter is that the temporary stop is released immediately when the release request is made by the trigger switch 2.

In step S30, the counter TIM
When the value of E is larger than "12", the interrupt processing is ended. Even if the singer sees the break point display (“‖” in FIG. 5) and presses the trigger switch 2 before the CPU 6 reads the break code from the performance data memory, the counter TIME indicates the break point. This is for canceling the temporary stop. When the value of the counter TIME is "12" or less, the CPU 6
Even if the trigger switch 2 is pressed before the break code is read by, the singer assumes that the singer has pressed the trigger switch 2 at the break point, and the process of canceling the pause is performed.

In the following step S32, the lyrics data at the position indicated by the lyrics data pointer is read from the lyrics data memory, and in step S33, it is determined whether or not the value of the timing counter coincides with the reproduction timing (the lyrics data display timing). To determine. When they match,
In step S34, the CPU 6 reads the character string of the lyrics data of the current timing and displays it on the display device 10, advances the lyrics data pointer to the next timing data in step S35, and increments the timing counter in step S36. After executing, the interrupt processing ends. On the other hand, when the value of the timing counter does not match the reproduction timing in step S33, steps S34 and S35 are skipped and the process proceeds to step S36.

Next, the processing operation of the CPU 6 will be specifically described using the example of the data shown in FIG.

As described above, since "TIMING 1" is set to a value smaller than "TIMING 2", the detection in step S33 is made earlier than the detection of the coincidence of the reproduction timing in step S27. The CPU 6 executes the process of step S34 to display the lyrics data shown in FIG. 5 on the display device 10.

Next, when the CPU 6 reads the break code from the performance data memory, the counter T is read in step S30.
The values of IME are compared, and the value of counter TIME is reset until the value becomes "12" or less, that is, the singer presses trigger switch 2 (step S1 in FIG. 6).
Continue the suspension until 1). When the singer presses the trigger switch 2 according to the displayed break point (as described above, even if the trigger switch 2 is pressed shortly before the CPU 6 detects the break code, the trigger switch 2 is pressed at that break point). ), Step S31
Then, the CPU 6 sets the timing counter to TIMING 2
Is set, the pointer is advanced to the next data in step S29, the CPU 6 reads TIMING 2 from the performance data memory in step S23, and compares it with the value set in the timing counter in step S27. At this time, since the value of TIMING 2 is set in the timing counter, the process proceeds to step S28, and key-on processing, key code ("D5") processing, etc. are executed while advancing the pointer.

In FIG. 4 (b), only the above-mentioned two chords are shown as chords to be processed at one time, but in reality, the music reproducing apparatus of this embodiment plays not only the melody line but also the accompaniment. In addition, various accompaniment data are also stored in the performance data memory.
In a loop from step 29 to step S23 through step S23, the CPU 6 executes various chord reproduction processing while advancing the performance data pointer. At this time,
When the timing designated by the performance data pointer and read by the CPU 6 is different from the reproduction timing, the process proceeds from step S27 to step S32, and the lyrics data indicated by the lyrics data pointer, that is, the lyrics of TIMING 1 in FIG. Data (“‖Erie‖…”)
Following, the lyrics data of TIMING 3 (not shown) is read, and the value of the timing counter is TI in step S33.
When it becomes MING 3, the read lyrics data is displayed on the display device 10 in step S34.

As explained above, when the music is temporarily stopped at the break point, the singer will use the trigger switch 2
Since the start time of the next music can be determined as desired, the depth of emotional empathy can be freely controlled.

In this embodiment, in order to cancel the temporary stop,
Although the trigger switch attached to the microphone is used, a foot-operated trigger switch 17 as shown in FIG. 8 may be used instead of the trigger switch. A foot-operated trigger switch, for example, attaches a vibration sensor to a mat placed on the stage,
The switch is turned on when the singer gives the mat a vibration of a predetermined value or more. This allows the singer to use his foot to determine when to start the next song.

Although the memory is used as the recording medium for recording the performance data, the present invention is not limited to this, and another storage medium such as a CD may be used. Also, MIDI standard data is stored in a storage medium as performance data, and is disclosed in, for example, Japanese Patent Laid-Open No. 4-1990.
The karaoke performance device described in Japanese Patent Publication No. 96 may be used for reproduction. Furthermore, instead of using a data code for performance data and generating a tone signal by recognizing the code by a tone generator as in this embodiment, digital recording data (PCM, DCC, MD, etc.) is used. May be stored in a storage medium and output directly to the sound system. At this time, as the reproducing device, the reproducing device described in JP-A-3-290696 can be used.

Further, instead of the trigger switch, a touch detecting function such as a pressure detecting device may be provided to control the volume of the musical sound according to the magnitude of the detected value. When a foot-operated switch is adopted, the value obtained from the vibration sensor may be used as the detection value. Further, the trigger switch may be shared with the tap tempo input switch. At this time, as the tap input device, the device described in Japanese Patent Application Laid-Open No. 3-282590 by the present applicant can be used.

Furthermore, in the present embodiment, an example in which the present invention is applied to a karaoke performance device has been described, but the present invention is not limited to this, and a manual performance with a keyboard may be performed while performing automatic accompaniment.
