The amplifier 18 amplifies the input analog musical tone signal, outputs it to the speaker 19, and generates musical tone via the speaker 19.

Next, the operation will be explained. In electronic musical instrument 1,
There is a recording mode and a playback mode for automatic performance. First, note information and performance control information for automatic performance are recorded in the recording mode, and then playback is performed in the playback mode based on the note information and performance control information recorded in the recording mode. automatically plays. Various operations in the recording mode and playback mode are performed using the performance operator 2 and various switches 3 to 9 shown in FIG.

Each mode will be explained below. Processing in Recording Mode When recording a song to be automatically played, first set the rhythm and tone, set the recording mode, and start automatic performance. That is, by operating the rhythm switch 6 of the electronic musical instrument 1, the rhythm No. , and operate the tone switch 5 to select the tone No. Set. Then,
A recording switch 8 is operated to set a recording mode, and when a rhythm is required, a rhythm start/stop switch 4 is turned on, and then an automatic performance start/stop switch 9 is started. By starting the automatic performance start/stop switch 9, the recording state is entered, so perform the performance using the performance operator 2 and input necessary note information.

In this recording mode, processing is performed in the electronic musical instrument 1 as shown in FIG. That is, when the power switch 3 is turned on, initialization processing is first performed (step S1), and it is checked whether the rhythm switch 6 is turned on (step S2). When the rhythm switch 6 is turned on, the rhythm number corresponding to the turned on rhythm switch 6 is selected. is stored in the performance control information area of the RAM 15 (step S3), and if the rhythm switch 6 is not turned on, the process directly advances to step S4. In step S4, it is checked whether the tone switch 5 is turned on, and when it is turned on,
Tone No. corresponding to the turned on tone switch 5. R
Store in the performance control information area of AM15 (step S
5). If the tone switch 5 is not turned on in step S4, the process directly proceeds to step S6, and it is checked whether the recording switch 8 is turned on (step S6).
.

[0023] Since we are now in automatic performance recording mode,
The recording switch 8 is turned on. Therefore, the process moves to step S7, and the state of the rhythm start/stop switch 4 is checked. When the rhythm start/stop switch 4 is in the start state, the rhythm flag is set to 1 (step S8), the state of the automatic performance start/stop switch 9 is checked (step S10), and the rhythm start/stop switch is set in step S7. When the switch 4 is in the stop state, the rhythm flag is set to 0 (step S9) and the automatic performance starts/
Check the state of the stop switch 9 (step S
10).

When the automatic performance start/stop switch 9 is in the stopped state, it is determined that the recording operation of the automatically performed song is not started yet, the start flag is set to 0 (step S11), and the process returns to step S2. Perform the same process. Automatic performance start/stop switch 9
If it is in the start state, it is checked whether the start flag is 1 (step S12). This start flag is a flag indicating whether or not the automatic performance start/stop switch 9 is turned on for the first time. When the automatic performance start/stop switch 9 is turned on for the first time, the start flag is 0. Since the automatic performance start/stop switch 9 is now turned on for the first time, the start flag is 0, and the process moves to step S13.
A start flag is set to 1, and a note length counter and a beat counter are started (step S14). The note length counter and beat counter utilize part of the registers of the CPU 12, and the note length counter is used to detect the type of note in the song, and the beat counter is used to detect the number of beats in the song. It is used for.

When the note length counter and the beat counter are started, the operating state of the performance operator 2 is checked (step S15), and if the operating state of the performance operator 2 is on, the scale data and the musical scale data of the performance operator 2 are checked. The value of the note length counter is read and written into the note information area of the RAM 15 (step S16). In step S15, when the performance controller 2 is off, the OFF data and the note length counter value are set to R.
Write in the note information area of AM15 (step S17)
. Further, in step S15, if there is no change in the state of the performance operator 2, no data is written to the RAM 15, and the process moves to step S18, where the rhythm flag is set to 1.
Check whether

When the rhythm flag is 1, that is, when it is determined in step S7 that the rhythm start/stop switch 4 is in the start state, it is checked whether the rhythm switch 6 has been switched (step S1).
9) When the rhythm switch 6 is switched, the rhythm No. of that rhythm switch 6 is changed. , Tone No. and beat count value to the RAM 15, and step S2
1 (step S20). If the rhythm flag is not 1 in step S18, it is determined that the rhythm start/stop switch 4 is in the stop state, and the process moves to step S21, and in step S19, the rhythm start/stop switch 4 is in the start state. When the rhythm switch 6 is not switched, the rhythm No. stored in the RAM 15 in step S3 is selected. It is determined that there is no change in , and the process moves to step S21.

In step S21, the tone switch 5
It is checked whether the rhythm flag has been switched, and if it has been switched, it is checked whether the rhythm flag is 1 (step 22). In step S22, when the rhythm flag is 1, the rhythm No. , the tone number corresponding to the switched tone switch 5. and beat count value in RAM
15 (step S23), and the scale data or OFF data stored in the RAM 15 in step S16 or step S17 and the RAM 1 in step S23.
At the same time, the tone data written in the rhythm No. 5 is transferred to the sound source LSI 16, and the rhythm data written in the rhythm No. 5 is transferred to the sound source LSI 16. Set the rhythm pattern (Step S
25). In step S22, when the rhythm flag is 0, the tone number corresponding to the switched tone switch 5 is
．． and the beat count value are written in the RAM 15 (step S24), and the R
The scale data or OFF data stored in the AM 15 and the tone data written in the RAM 15 in step S24 are transferred to the sound source LSI 16 (step S25). At this time, since the rhythm flag is 0, no rhythm pattern is set. When scale data and the like are set in the sound source LSI 16 in this manner, the sound source LSI 16 generates musical tones through normal operations and outputs the musical tones to the D/A converter 17. As a result, musical tones corresponding to the scale data and tone color data are output from the speaker 19.

Through the above processing, the data necessary for automatic performance, such as the tone, rhythm, scale, and beat count inputted by the performance operator 2 and each switch 4 to 6, is stored in the RAM 1.
5, and the corresponding musical tone is generated from the speaker 19.

When the process up to the generation of musical tones is completed, the process returns to step S6 and the same process is repeated, thereby storing sequentially inputted note information and performance control information in the RAM.
15, and can be output as musical tones from the speaker 19.

When the automatic performance start/stop switch 9 is operated and the automatic performance start/stop switch 9 is in the stop state while the above processing is being repeated in sequence, the start flag is set to 0 (step S11), and the process returns to step S2 to switch the rhythm switch. 6 is switched, tone switch 5 is switched, recording switch 8 is turned off, rhythm start/stop switch 4 is switched, etc. (steps S2, S4, S6, S7). When each switch is operated, corresponding processing is performed (steps S3, S5, S8, S9). Step S1
0, when the automatic performance start/stop switch 9 is switched to the start state again, the same processing as described above is performed corresponding to the state of each of the switches. In step S6, when the recording switch 8 is turned off, the recording mode is ended and a transition is made to a reproduction mode (automatic performance mode) to be described next.

Processing in playback mode The playback mode is a mode in which musical performance is performed automatically based on the note information and performance control information recorded in the RAM 15 in the recording mode, and during this playback mode, the performance control information is displayed on the display unit 10. .

That is, when the recording switch is turned off in step S6 of FIG. 4, the process moves to step S26 of FIG. 5, and initial settings for starting the playback mode are performed. In other words, the current address is 1000H
and set the display confirmation switch to 000H. The reason why this current address is set to 1000H is to set the start address of the performance control information area in which performance control information is stored. Further, the initial value 000H is set as the current number of beats, and 000H is set as the 1-second counter. When the initial setting of the playback mode is completed, the state of the automatic performance start/stop switch 4 is checked (step S27), and if the automatic performance start/stop switch 4 is in the stopped state, it is determined that automatic performance will not be performed yet, Set the start flag to 0 (step S
28), return to step S2 in FIG.

In step S27, when the automatic performance start/stop switch 4 is in the start state, it is determined that automatic performance is to be started, and it is checked whether the start flag is 1, that is, whether automatic performance has started (step S29). When the start flag is 0, it is determined that it is an initial start, and the note length counter and beat counter are started (steps S30, S31), and the start flag is set to 1 (step S32). Next, RAM1
The first note information and performance control information are read out from 5 (step S33), and based on the read note information and performance control information, the scale data and timbre data are transferred to the sound source LSI 16.
At the same time, a rhythm pattern is set (step S34). Thereby, a musical tone is generated from the sound source LSI 16, and after the generated musical tone is converted into analog by the D/A converter 17, it is transferred to the speaker 19 via the amplifier 18, and is generated from the speaker 19.

Next, it is checked whether the count value of the tone length counter has reached the value of the tone length data, that is, whether musical tones have been generated for the duration of the tone length data (step S35), and the count value of the tone length counter is checked. When matches the value of the note length data, the address is incremented by 1, the next note information is read from the RAM 15 (step S36), and it is checked whether the data is scale data (step S37). When the note information is scale data, the scale data is transferred to the sound source LSI 16,
A musical tone of that scale is generated (step S38). When the scale data is not scale data, that is, OF
When it is F data, OFF data is transferred to the sound source LSI 16 and generation of musical tones is stopped (step S39). Note that if the count value of the note length counter and the value of the note length data do not match in step S35, the process moves to step S40 without reading or setting the next note scale data.

In step S40, it is checked whether the count value of the beat counter and the beat data match. If they do not match, the process returns to step S35 to check the note length counter and note length data and perform the same processing. In step S40, when the count value of the beat counter and the beat data match, the address counter is incremented by 1 and the next performance control information is read from the RAM 15 (
Step S41), it is checked whether the performance control information is stop data (step S42). When the performance control information is stop data, it is determined that the reproduction mode is to be stopped, the process moves to step S28, the start flag is set to 0, and the process moves to step S2.

In step S42, if the performance control information is not stop data, the tone data of the performance control information read out in step S41 is transferred to the sound source LSI 16 and a rhythm pattern is set (step S43).
It is checked whether the display confirmation switch 7 is turned on (step S44). Here, when the display confirmation switch 7 is turned on, the flow shifts to the display processing flow of FIG. 6, and when the display confirmation switch 7 is not turned on, the flow shifts to the display processing flow of FIG. 7.

Display Processing In FIG. 6, since the display confirmation switch 7 has now been turned on, it is checked whether one second or more has elapsed since the display confirmation switch 7 was turned on until it is next turned on. 1 second counter (step S4)
5) Increment the number of times the display confirmation switch is turned on by 1 (step S46). This one second counter is shown in Figure 3.
As shown in FIG. 2, the control data area of the RAM 15 is reserved. Next, the contents of the performance control information area ahead of the address indicated by the current location address counter by the number of times the display confirmation switch is turned on are read from the RAM 15 (step S4
7) Check whether the content of the performance control information in that area is stop data (step S48). If it is stop data, it is the last data of the performance control information, so the number of times the display confirmation switch is turned on is decremented by 1 (step S49), and the process moves to step S50. If it is not stop data, the process continues to step S50.
to move to. In step S50, the difference between the current beat number and the beat number of the performance control information that is the number of times the display confirmation switch is turned on is calculated, and as shown in FIG. The content of the performance control information and the display unit 10
and display it on the display unit 10 (step S50
).

[0038] Therefore, it is possible to display how the performance control information such as timbre and rhythm changes from the measure currently being played, and how the automatically played song will change from now on. This can be known from the display on the display unit 10. As a result, when practicing on another musical instrument while making the electronic musical instrument 1 perform automatically, the performance control information displayed on the display section 10 can be sequentially switched by turning on the display confirmation switch 7 as a switching means. This allows you to see how the performance control information changes in measures after the measure being played, such as when practicing on another musical instrument while automatically playing with an automatic performance device. As a result, the usability of the electronic musical instrument 1 as an automatic performance device can be improved. Furthermore, when the performance control information is the final data and its content is stop, the number of times the display confirmation switch is turned on is decremented by 1, and the final data can be displayed even if the display confirmation switch 7 is turned on from now on. can. In addition,
In this case, the final data may not be displayed, but the display may be returned to the current playing position, and the display may be switched in accordance with the number of times the display confirmation switch 7 is turned on.

On the other hand, if the display confirmation switch 7 is not turned on in step S44 of FIG. 5, the process moves to the process of FIG. 7, and first, it is checked whether the one second counter has counted one second (step S51). When the one second counter counts one second, the one second counter is cleared (step S52), and the number of times the display confirmation switch is turned on is set to 0 (step S53). Next, check whether the number of times the display confirmation switch is turned on is 0 (step S
54). Now, since the number of times the display confirmation switch is turned on is set to 0 in step S53, the process moves to step S55.
As shown in Figure 9, the current beat rate ("5" in Figure 9) and "
NORMAL" is displayed, and the process returns to step S27 in FIG. This "NORMAL" display indicates that the content displayed on the display section 10 is the number of beats currently being played. Note that the display contents when the display confirmation switch 7 is not turned on are not limited to this "NORMAL" display, but include, for example, the beat number, tone color, and performance control information for the measure currently being played. You may display all the rhythms, etc. or only the necessary ones.
Also, information on the notes being played may be displayed.

In step S51, if the one second counter is not counting one second, the one second counter is not cleared and the number of times the display confirmation switch is turned on is not reset.
Proceeding to step S54, it is checked whether the number of times the display confirmation switch is turned on is 0. If the number of times the display confirmation switch is turned on is 0, the current beat number and "NORMAL" are displayed, and the process returns to step S27 in FIG. S55). In step S54, if the number of times the display confirmation switch is turned on is not 0, the process moves to step S50 in FIG.

That is, when the display confirmation switch 7 is not turned on in FIG. 5, it is checked whether the display confirmation switch 7 has not been turned on for one second, and the display confirmation switch 7 has not been turned on for one second. When the display confirmation switch 7 is not turned on, processing corresponding to the number of times the display confirmation switch 7 is turned on is performed, and if the display confirmation switch 7 is not turned on for one second, the one second counter is cleared and the number of times the display confirmation switch 7 is turned on is reset. Return to the initial display state.

To explain the recording process and playback process in more detail, as shown in FIG. 10, when recording is started in the recording mode, the number of beats is counted, and the first set tone number is counted. (In Figure 10, tone N
o. 2) and rhythm no. (In Figure 10, rhythm No.
．． 1) is stored in the RAM 15. At the 8th beat, rhythm switch 6 No. When 4 is input, that beat number and rhythm number are entered. The data of 4 is stored in the RAM 15, and the data of 14
On the beat, turn the tone switch 5 to No. When 3 is inserted,
The number of beats and tone No. 3 is stored in the RAM 15. After that, when the automatic performance start/stop switch 9 is turned on at the 20th beat, the beat number and stop data are
It is stored in AM15.

Once the note information and performance control information to be automatically played are stored in the RAM 15 in this manner, automatic performance becomes possible in the playback mode. That is, when the recording switch 8 is released and the automatic performance start/stop switch 9 is set to START, the playback mode is started. First, the initial state is read from the RAM 15, and as shown in FIG. Display “NORMAL”. Now, as shown in FIG. 10, the beat number is the 6th beat, and if the display confirmation switch 7 is turned on, the number of beats up to the beat number of the performance control information different from the measure currently being played is displayed. The difference is calculated, and the difference in the number of beats and the performance control information with the number of beats of the different performance control information are displayed on the display unit 10. In the case shown in FIG. 10, the display confirmation switch 7 is turned on at the 6th beat, and the next beat number for which the performance control information changes is 8, so the display section 10 shows the beat number as shown in FIG. 2 (8-6=2
) and the tone number as its performance control information. 2 and rhythm no. 4 is displayed. Here, if the display confirmation switch 7 is turned on again within one second, the difference in the number of beats from the number of beats at which the performance control information will change next, and the timbre No. that is the performance control information after the change. 3 and rhythm no. 4 is displayed on the display section 10.

[0044] Therefore, it is possible to display how the performance control information such as timbre and rhythm will change from the measure currently being played, and how the automatically played song will change from now on. This can be known from the display on the display unit 10. As a result, when practicing on another musical instrument while making the electronic musical instrument 1 perform automatically, the performance control information displayed on the display section 10 can be sequentially switched by turning on the display confirmation switch 7 as a switching means. This allows you to see how the performance control information changes in measures after the measure being played, such as when practicing on another musical instrument while automatically playing with an automatic performance device. As a result, the usability of the electronic musical instrument 1 as an automatic performance device can be improved.

Note that the note length counter, beat counter, and one second counter are performed by interrupt processing (interruption processing) using a clock input to the CPU 12 at a constant cycle.

That is, as shown in FIG.
2 is interrupted by a clock input at a constant cycle, and first the tone length counter is incremented (step T1) and the beat counter is incremented (step T2). Next, it is checked whether the mode is playback mode (step T3), and if it is not the playback mode, the next interrupt processing is performed as is. In step T3, when the playback mode is selected, a one-second counter is incremented (step T4), and the next interrupt process is performed.

FIG. 12 is a diagram showing an embodiment of an automatic performance device according to the invention as claimed in claim 2. This example is shown in Figure 1 above.
, is applied to an electronic musical instrument similar to the electronic musical instrument 1 shown in FIGS. 2 and 3, and in explaining this embodiment, the same reference numerals will be used for the same components, and the description thereof will be omitted. .

In this embodiment, once the display confirmation switch 7 is turned on, the performance control information is automatically switched and displayed on the display section 10 at predetermined time intervals. Therefore, in the display processing of this embodiment, as shown in FIG.
~ Of the flowcharts shown in Figures 7 and 11, Figure 4
, FIG. 5 and FIG. 11 are the same process, and FIG. 6 and FIG. 7 are replaced with FIG. 12.

Therefore, in explaining this embodiment, FIG.
Assuming that the processing of FIGS. 5 and 11 is performed, FIG.
2 will be explained.

In step S44 of FIG. 5, it is checked whether the display confirmation switch 7 is turned on, and if it is turned on, the process goes to step P1 of FIG. 12, and if it is not turned on, the process goes to step P12 of FIG. do.

If the display confirmation switch 7 is not turned on in step S44 of FIG. 5, the process moves to step P12 of FIG.
It is checked whether the flag (indicating whether the display confirmation switch 7 has been turned on) is 1, which indicates that the display confirmation switch 7 has been turned on. Here, if the display confirmation switch 7 has never been turned on, the on flag is 0, so step P11
The current beat number and "NORMAL" data are output to the display section 10 and displayed on the display section 10 as shown in FIG. 9 above.

After that, when the display confirmation switch 7 is turned on, first, in step S44 of FIG. 5, it is recognized that the display confirmation switch 7 has been turned on, and step P1 of FIG.
, and sets the on flag to 1. When the on flag is set, the number of times the display confirmation switch is turned on is set to 0 (step P2), and the 1 second counter is cleared (
Step P3). Next, the content of the performance control information area ahead by the number of times the display confirmation switch is turned on is read from the address indicated by the current location address counter (step P4), and it is checked whether the content of the read performance control information is stop data (step P5). If it is not stop data, calculate the difference between the current beat number and the beat number of the performance control information that is the number of times the display confirmation switch is turned on, and then calculate the difference between the beat numbers of this calculation result and the number of beats that are the number of times that the display confirmation switch is turned on. The contents of the performance control information are output to the display section 10 and displayed on the display section 10 as shown in FIG. 8 (Step P6).

Thereafter, it is checked whether the 1 second counter has counted 1 second (step P7), and if the 1 second counter has not counted 1 second, the process moves to step S27 in FIG. 5, and the process described above is performed. Do the same thing. Here, when the 1 second counter counts 1 second, the number of times the display confirmation switch is turned on is incremented by 1 (step P8), and the process proceeds to step P3, where the 1 second counter is cleared. In this state, as shown in FIG. 11, the note length counter, beat counter, and one second counter are incremented, that is, counting processing is performed.

When the one-second counter is cleared in step P3, the contents of the performance control information area are read out from the address indicated by the current location address counter by the number of times the display confirmation switch is turned on (step P4). It is checked whether the content of the performance control information is stop data (step P5). If the data is not stop data, the process moves to step P6 in the same manner as described above to calculate the difference between the current beat number and the beat number of the performance control information that is the number of times the display confirmation switch is turned on, and calculates the number of beats as a result of this calculation. The difference and the content of the performance control information for the number of times the display confirmation switch is turned on are outputted to the display section 10 and displayed on the display section 10 as shown in FIG. 8 above.

Therefore, once the display confirmation switch 7 is turned on, every time the 1 second counter counts 1 second, the performance control information stored in the performance control area of the RAM 15 is changed. Information can be sequentially read out and displayed on the display unit 10. the result,
The performance control information can be sequentially switched and displayed without performing a switching operation using the display confirmation switch 7, and the electronic musical instrument 1 can be used as an automatic performance device when playing other musical instruments etc. in accordance with the automatic performance. can be further improved.

In step P5, when the content of the performance control information read from the RAM 15 is stop data, the process moves to step P9, where the number of times the display confirmation switch is turned on is set to 0, and the on flag is set to 0 (step P9). P10). That is, the fact that the performance control information is stop data indicates that the performance control information stored in the arithmetic control information area is the final data. Therefore, the number of times the display confirmation switch is turned on is set to 0, and the on flag is set to 0, the above-mentioned performance control information switching and display processing is once completed, and then the same processing is performed after waiting for the display confirmation switch 7 to be turned on again. Do the following.

[0057] When the number of times the display confirmation switch is turned on and the reset of the on flag is completed, the current number of beats and "NORMA
L'' data is output to the display section 10 and displayed on the display section 10 (step P11).

Therefore, once the display confirmation switch 7 is turned on, the contents of the performance control information can be switched every second and displayed on the display section 10 in sequence, and when the display of the performance control information is completed to the end. , when the switching display is finished and the display confirmation switch 7 is turned on next, the contents of the performance control information can be sequentially switched and displayed in the same way. As a result, the performance control information can be sequentially switched and displayed without performing a switching operation using the display confirmation switch 7, and the electronic musical instrument 1 can be used as an automatic performance device when playing other musical instruments in time with the automatic performance. The usability of the system can be further improved.
