[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument for measuring the actual playing time.

[0002]

2. Description of the Related Art Conventionally, there has been proposed an electronic musical instrument for displaying performance time, performance practice time (hereinafter, simply referred to as performance time), and progress of performance. In this electronic musical instrument, when the power of the electronic musical instrument is turned on, the timer is started to start measuring the playing time, and the timer is stopped when the performance or practice is completed. Stop timing. The time measured by the timer, that is, the playing time is L
In addition to displaying the information on a CD or the like, the degree of progress is evaluated based on the relationship between the performance time and the performance operation error, and the result is displayed. Thereby, the person practicing the performance can objectively grasp the progress speed of his or her performance technique from the displayed performance time and progress.

[0003]

However, in such an electronic musical instrument, as described above, the timer is started when the power is turned on, and the timer is stopped when the performance or performance practice is completed. It is configured to time. Therefore, if you do not start playing or practicing immediately after power-on, but have made the necessary preparations for the start of the performance, such as the preparation of the score, the timer that counts with the power-on,
The non-playing time during that time is counted. The same applies to a case where the performance is interrupted and a break is performed, during which time the timer continues counting. Therefore, the timer time value after the end of the performance will probably include a non-performance time as an error in addition to the time when the player actually performs the performance operation, and the actual performance time can be accurately timed. It was not something.

[0004] The present invention has been made in view of such conventional problems, and has as its object to provide an electronic musical instrument capable of measuring the actual playing time with higher accuracy.

[0005]

According to the present invention, in order to solve the above-mentioned problems, the present invention relates to performance operation means for outputting performance data by performing a performance operation, and based on the performance data output from the performance operation means. Tone signal control means for performing control relating to generation of a tone signal; first time counting means for starting timekeeping in response to a first performance operation on the performance operation means after power-on; Second timing means for timing an operation interval; and stopping the timing of the first timing means when the operation interval timed by the second timing means is equal to or greater than a predetermined value; And a timing control means for restarting the timing of the stopped first time counting means in response to a performance operation on the musical instrument.

In another configuration of the present invention, a performance operation means for outputting performance data by performing a performance operation, and operating based on the performance data output from the performance operation means to generate a tone signal. Music signal control means for executing related control; first time measurement means for starting time measurement in response to a first performance operation on the performance operation means after power-on; and non-operation time of the music signal control means. Second timing means for timing, and stopping the timing of the first timing means when the non-operation time counted by the second timing means is equal to or more than a predetermined value; A timing control means for restarting the timing of the stopped first timing means in response to an operation.

Further, in another configuration of the present invention, the second timekeeping means operates when the performance operation means is not operated and the tone signal control means is not operated. Means, when the time counted by the second time counting means is equal to or greater than a predetermined value, stopping the timing of the first time counting means and stopping the time in response to a performance operation on the performance operation means. A timing control means for restarting the timing of the first timing means. Further, it is preferable that display means for displaying the content of timing of the first timing means is further provided, and the predetermined value is variably set by an external operation.

[0008]

In the above arrangement, the first time counting means starts time counting from the time of the first performance operation after the power is turned on. On the other hand, the second timing means measures the operation interval for the performance operation means, or measures the non-operation time of the tone signal control means, or the performance operation means is in the non-operation state, and the tone signal control means The timer operates when is inactive. When each of the times measured by the second time counting means is equal to or more than a predetermined value, the time control means stops the time counting of the first time counting means. When the operation of the performance operator, that is, the performance operation, is performed in a state where the first timer is stopped, the first timer restarts timing in response to the operation.

Therefore, in each configuration of the present invention, the first

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. That is, FIG. 1 shows the overall configuration of an electronic musical instrument common to each embodiment.
Are data and programs stored in the ROM 2, RA
Based on data or the like temporarily stored in M3, all controls necessary for this electronic musical instrument are executed. Operation information from the performance operation unit 4 is input to the microcomputer 1 via the event detection unit 5 and operation information is input from the panel switch unit 6. The performance operation unit 4 includes a keyboard having a plurality of keys arranged in order of pitch, a pedal operated when changing the pitch, and other components (for example, a pitch operated when changing the pitch continuously). (Vendors, etc.). The event detection unit 5 includes a keyboard switch that is provided for each key and is turned on when a key is pressed, a pedal switch that is turned on when a pedal is operated, and the like. Is output.

The panel switch section 6 includes a power switch for turning on the power of the electronic musical instrument, a tone switch for selecting and setting a tone, a tempo-up switch and a tempo-down switch for changing the tempo of an automatic performance. A time setting switch for setting a predetermined time T, which will be described later, is provided in addition to switches, such as switches, which are usually provided in the electronic musical instrument. Then, the microcomputer 1 instructs the sound source 7 to generate a tone signal based on data from the performance operation unit 4 input through the event detection unit 5 and data from the panel switch unit 6. The tone generator 7 generates a tone signal in accordance with an instruction given by the microcomputer 1, and the tone signal is converted into an analog signal by a D / A converter 8, amplified by an amplifier 9, and emitted from a speaker 10.

(1) First Embodiment Next, the operation of the first embodiment of the present invention will be described with reference to the flowcharts shown in FIGS. In the first embodiment, the CPU 1 has a timer for counting the playing time and a timer for counting the time between events, and the counted values of both timers are stored in the work area of the RAM 3. That is, FIG. 2 shows the main flow of the present embodiment. When the power switch is turned on, the microcomputer 1 starts the operation according to this flow, and first performs the initial setting (S
A1). By this initial setting, the performance time timer and the inter-event time timer are reset to zero and the work area of the RAM 3 is cleared.

Subsequently, switch and mode processing (SA
2), this switch and mode processing are performed according to the flow shown in FIG. 3, and first, the switch group provided in the panel switch section 6 is scanned (SB).
1), capture the operation state. Next, it is determined whether or not the time setting switch has been turned on (SB2). If the time setting switch has been turned on, a predetermined time T corresponding to the operation of the time setting switch is stored (SB3). Further, it is determined whether or not another switch other than the time setting switch, such as a tone switch, has been turned on (SB4). If the switch has been turned on, a process corresponding to the operated switch is executed (SB5). . Therefore, when the player operates the time setting switch to set an arbitrary time at the start of the performance, the predetermined time T set by the player by the switch and the mode processing is set in a predetermined memory area of the RAM 3 in advance.

Then, in the main flow of FIG.
Subsequent to the switch and mode processing (SA2) constituted by the determination processing of B1 to SB5, event processing (SA3) is executed, and this event processing is performed according to the flow shown in FIG. That is, based on an input signal from the event detection unit 5, it is determined whether or not there is an event related to a performance operation such as a key press, a key release, or a pedal on / off operation (SC1). After turning on the power with the power switch turned on, it is determined whether or not this is the first event (SC2). If it is the first event, the timer for counting the time between events is started (SC5), and the timer for counting the playing time is started (SC6). Subsequently, event data processing (SC9) is performed, and NOTE-ON, NOT
Data corresponding to an event such as E-OFF, PEDAL-ON, PEDAL-OFF is generated, and the process returns.

Then, when SC1 is discriminated again, if there is no event, the process proceeds from SC1 to SC7,
It is determined whether or not the inter-event time measured by the inter-event time counting timer is equal to or longer than the predetermined time T (SC7). If the inter-event time is shorter than the predetermined time T, the process returns. When the time becomes equal to or longer than the predetermined time T, the playing time timer is stopped (SC8), and the process returns.

Next, when the player performs a performance operation such as a key press or a key release, and there is an event, a transition is made from SC1 to SC2, but this event is not the first event from power-on. Therefore, proceed from SC2 to SC3, and
After clearing the timer for measuring the time between events, which is started and continuing the time counting, it is determined whether or not the timer for measuring the playing time is stopped (SC4). If the performance time counting timer is stopped by the above-described process of SC8, the performance time counting timer is started (SC6), and the event data processing (SC9) is started.
Is executed, and if not stopped, only the event data processing (SC9) is executed and the routine returns.

That is, the event processing SC1 to SC
9 will be described with reference to FIG. 5. In FIG. 9, each white circle group indicates an event timing. In this embodiment, the power is turned on (Po) as described above.
Since the timing of the performance time and the timing of the inter-event time are started at the first event timing from (Wer On), the performance time of the graph line and the inter-event time of the graph line start at the first event timing,
The time between events is reset for each event. The inter-event time is always compared with a predetermined time T indicated by an arrow. When the player takes a break or the like, and the inter-event time exceeds the predetermined time (the state of the timing line), the performance is performed. The timing of the time is stopped, and the timing of the performance time is started again at the event timing 'at which the next performance operation is performed.

In FIG. 1, the origin (Power O)
The straight line extending from n) indicates the performance time measured by the conventional device that keeps measuring time after the power is turned on. As is clear from the comparison between the performance time of the conventional device and the performance time of the present embodiment, There is a difference in the measurement time. That is, in this embodiment, the time from the power-on to the first event timing, or the time from the time between events exceeding the predetermined time to the next event timing (〜 ') = precise performance not including break time, etc. The time can be measured by a playing time timer.

In the main flow shown in FIG. 2,
After executing the event processing (SA3) as described above,
The tone control process (AS4) corresponding to each event is executed, and the NOTE-ON, NOT generated at SC9 in FIG.
Based on data corresponding to events such as E-OFF, PEDAL-ON, PEDAL-OFF, etc., the sound source 7 is instructed to sound and mute. Subsequently, the performance time display processing (S
According to A5), the display data of the accurate playing time measured by the playing time timer is transferred to the display unit 11, and the present value of the playing time timer is displayed on the display unit 11 while being sequentially updated. Is done. As a result, the player can grasp the exact playing time that does not include the loss time up to the first event timing or the break time from the time value displayed on the display unit 11.

(2) Second Embodiment In a second embodiment of the present invention, the main flow (FIG. 2) and event processing (FIG. 4) are the same as those in the first embodiment.
Only the main flow switch and mode processing (SA2) are different from those of the first embodiment. That is, FIG. 6 is a flowchart showing the contents of the switch and mode processing of the second embodiment. First, the switch group provided in the panel switch section 6 is scanned (SD1), and the operation state is fetched. Next, it is determined whether or not a tempo-up switch provided in the panel switch section 6 has been turned on (SD2). If the tempo-up switch has been operated, the value of the tempo N is counted up (SD2). SD3). The tempo N is set to a predetermined initial value in the initial setting (SA1) in FIG. If the tempo-up switch has not been turned on, it is determined whether the tempo-down switch has been turned on (SD4). If the tempo-down switch has been operated, the value of the tempo N is counted down (SD4). SD5). Next, using a conversion table prepared in advance in the ROM 2, the tempo N is converted into a corresponding predetermined time T, and the predetermined time T corresponding to the tempo N is stored in the work area of the RAM 3. Further, it is determined whether or not another switch such as a tone switch other than the time setting switch is turned on (SD).
7) If the switch is turned on, the process corresponding to the operated switch is executed (SD8).

That is, in the second embodiment, the predetermined time T can be set to an arbitrary value by operating the tempo up switch and the tempo down switch. Therefore, for example, if the time interval between key depression and key release is long and the time interval between key depression is long, such as when playing a song that includes a long rest, Sets the predetermined time T to a large value. As a result, it is possible to prevent the inconvenience of stopping the performance time counting timer exceeding the predetermined time T during the time interval from the key press to the key release or the performance of the rest part. It is possible to measure a long playing time.

(3) Third Embodiment FIG. 7 shows a main flow of a third embodiment of the present invention.
Starts the operation according to this flowchart, and first performs initial setting (SE1). With this initial setting, this third
The performance time timer and the non-musical sound control time timer used in the embodiment are reset to 0,
The memory storing the predetermined time T is cleared.

Subsequently, switch and mode processing (SE
2), and this switch and mode processing are performed according to the flow shown in FIG. 3 or FIG.
Subsequently, an event process (SE4) is executed. This event processing is performed according to the flow shown in FIG. 8, and based on an input signal from the event detection unit 5, it is determined whether or not there is an event related to a performance operation such as a key press, a key release, or a pedal on / off operation. It is determined (SF1). If there is an event, it is determined whether or not the event is the first event after the power is turned on (SF2). If the event is the first event, a performance time timer is started (SF6). Subsequently, it is determined whether or not the non-musical sound control time counting timer started in the musical sound control processing described later is operating (SF4), and if it is stopped, only the event data processing is performed (SF5). . If the non-musical sound control time counting timer is in operation, the non-musical sound control time measuring timer is stopped and cleared (SF7), and event data processing is performed (SF7).
8), NOTE-ON, NOTE-OFF, PEDAL
Generate data corresponding to an event such as -ON, PEDAL-OFF, etc., and return.

In the main flow of FIG. 7, following the event processing (SE3), the tone control processing (SE4)
The tone control process is performed according to the flowchart shown in FIG. 9, and it is first determined whether or not tone control is performed (SG1). Here, the presence / absence of the tone control means whether or not the microcomputer 1 is in a state to execute the control related to the generation of the tone signal, and is performed by the microcomputer 1 from note-on until the envelope becomes “0”. Control to be performed. If the tone control is to be executed, tone processing such as instructing the sound source 7 to generate a tone waveform is executed in accordance with the current state of the envelope (SG).
2). Next, it is determined whether or not all the tone controls have been completed, that is, whether or not the envelopes of the tone generated by the tone control have all become "0" and the tone control has not been performed ( SG3). When all the tone controls have been completed, the non-tone control time timer is started (SG4), and the non-tone control time starts counting from the non-tone control time timer.

In the main flow of FIG. 7, a performance time stop process is executed following this tone control process (SE4) (SE5), and the performance time stop process is performed according to the flowchart shown in FIG. That is, S in FIG.
It is determined whether the non-tone control time measured by the non-tone control time timer started at G4 is longer than a predetermined time T (SH1), and the non-tone control time is longer than the predetermined time T. When the time becomes, the performance time timer is stopped (SH2). When the timer for measuring the performance time is stopped in SH2, if there is a next event, the determination of SF3 in FIG.
The process advances from F3 to SF6, and the stopped performance time timer is started.

That is, the event processing, tone control processing, and performance time stop processing in FIGS. 8, 9 and 10 will be described with reference to FIG. 11. In FIG. 11, white circles indicate event timings. In the third embodiment, the performance time starts at the first event timing after power-on, as described above, so that the performance time of the graph line starts at the first event timing. Also, the time chart shows the state of the musical tone control processing corresponding to each event,
This tone control process is performed for each tone generation channel corresponding to an event. The time length of the tone control process in each sounding channel differs depending on the event. For example, when the key-pressed state is long and the envelope is slowly attenuated, the time required for the tone control process is also long. Then, in the third embodiment, the non-musical sound control time counting timer is started from (timing of) when all the musical sound control processes performed for each sounding channel are completed. Is the measured value of the non-tone control time timer, that is, the non-tone control time,
The non-tone control time is compared with a predetermined time T indicated by an arrow, and when the player takes a break, the non-tone control time () is used.
If the time exceeds the predetermined time T () (the state of the timing line), the performance time () is stopped, and timing of the performance time is started again at the event timing 'at which the next performance operation is performed.

That is, in the first and second embodiments, when the time between events becomes equal to or longer than the predetermined time T, the performance time timer is stopped. If the time between events exceeds a predetermined time T during the decay of the envelope, as in the case where the envelope is producing a musical sound that slowly decay, the playing time timer is stopped and the playing time is reduced. The timing stops temporarily. Therefore, when the performance is being performed while generating a musical tone whose envelope slowly decays, the performance time timer is stopped and the performance time is not measured even though the performance is being performed (= playing). In some cases, there is an error between the actual playing time and the measured playing time.

However, in the third embodiment, FIG.
As shown in FIG. 1, the non-tone control time () is equal to the predetermined time T.
In the state of the timing line exceeding (), the timing of the performance time () is stopped. Therefore, when the tone is controlled during the period, such as when the envelope is generating a tone that slowly decays, the non-tone control timer does not operate, and the non-tone control time naturally exceeds the predetermined time T. Never exceed. Therefore, even when a performance is performed in which a musical tone whose envelope slowly decay is generated, no error occurs between the actual performance time and the measured performance time, and the performance time is more accurately measured. Can be timed. Thereby, when the performance time display processing is performed in SE6 in the main flow of FIG. 7, the performance time measured more accurately can be displayed on the display unit 11.

(4) Fourth Embodiment The fourth embodiment of the present invention is the same as the third embodiment shown in FIG. 7 with respect to the main flow. However, the initial setting (S
In E1), the performance time timer and the non-performance time timer used in the fourth embodiment are reset to zero, and the memory for storing the predetermined time T is cleared. Subsequently, switch and mode processing (SE2) is executed. This switch and mode processing is performed according to the flow shown in FIG. 3 or FIG. 6 as described above, and subsequently, event processing (SE4) is executed. This event processing is performed according to the flow shown in FIG. 12, and the contents of the event processing shown in FIG. 12 are almost the same as the contents of the event processing of the third embodiment shown in FIG. However, while the third embodiment measures the non-tone control time using the non-tone control time timer, the fourth embodiment measures the non-performance time using the non-play time timer. Accordingly, in SI4 and SI7 corresponding to SF4 and SF7 in FIG. 8, it is determined whether or not the non-performance time counting timer is operating. , This is stopped and cleared.

In the main flow of FIG. 7, following the event processing (SE3), a tone control processing (SE4)
The tone control process is performed in accordance with the flowchart shown in FIG. 13. In this flowchart, the determination processes of SJ1 to SJ3 are the same as those of SG1 to SG3 of the third embodiment shown in FIG. And SJ
In SJ4 following 3, it is determined whether or not all the OFF operations for the ON operation have been completed. Here, the OFF operation for the ON operation is an OF operation for the ON operation of the performance operator.
F operation, a key release (OF operation) for a key press (ON operation)
F operation). Therefore, if the depressed key has not been released even after all the tone controls have been completed, the routine returns, indicating that all the tone controls have been completed and all the key releases for the depressed keys have been completed. As conditions, SJ4 to SJ
Go to 5. Then, in SJ5, it is determined whether or not the non-performance time counting timer is in operation. If not, the non-performance time counting timer is started. Therefore,
In order for this non-performance timer to start,
The condition is that all musical tone controls have been completed and all key release for key depression has been completed.

In the main flow of FIG. 7, a performance time stop process is executed following this tone control process (SE4) (SE5), and the performance time stop process is performed according to the flowchart shown in FIG. That is, SJ6 in FIG.
It is determined whether or not the non-playing time counted by the non-playing time timer started in step S1 is longer than a predetermined time T (SK1). To stop the performance timer (SK2). When the performance time counting timer is stopped at SK2, if there is a next event, the above-described determination of SI3 in FIG.
From step SI6 to start the stopped performance time timer.

That is, the operation of the fourth embodiment will be described with reference to FIG. 15. In FIG. 15, the white circles indicate the on-operation of the performance operation timing, and the black circles indicate the off-operation. In the fourth embodiment, as described above, the performance time starts at the first event timing after the power is turned on, so that the performance time of the graph line starts at the first event timing. The time chart shows the state of the tone control process corresponding to each event, and this tone control process is performed for each tone generation channel in response to the event. Further, the time length varies depending on the event. For example, when the key is kept depressed for a long time and the envelope is slowly attenuated, the time required for the musical tone control process is also long.

The non-performance time counting timer for measuring the non-performance time is shown in FIG.
As described in 3 to SJ6, the process is started on condition that all tone control has been completed and all OFF operations for ON operations have been completed. Then, at the timing of the timing line in FIG. 15, the tone control process has been completed, and there are three white circles and three black circles on the left side of the timing line.
All the OFF operations (●) for the operation (）) have been completed. Therefore, the timing satisfies the condition that all tone controls have been completed and all OFF operations for ON operations have been completed. Therefore, the timing of the non-performance time is started from this timing, and the non-performance time is compared with the predetermined time. At the timing line where the non-performance time exceeds the predetermined time, the performance time timer is stopped, and the performance time is stopped. The timing of the time is stopped, and the timing of the stopped performance time is restarted at the next event timing '.

Further, the tone control processing has been completed at the timing of the timing line '. However, the number of white circles is four, while the number of black circles is four in the time area a from the timing restart of the performance time at the event timing 'to the timing line'. Therefore, one of
The OFF operation (●) for one ON operation (（) has not been performed yet, and all the OFF operations (）) for the ON operation (）) have not been completed. In this state, for example, five keys are depressed in the time area a, and four keys are released, but the remaining one key is kept depressed and not released. Therefore, in this case, the timing of the non-playing time ′ virtually indicated by the dotted line is not performed, so that the timing of the playing time is not stopped, and the third embodiment and the fourth embodiment are not performed at this timing. There is a difference in operation and effect from the embodiment.

FIG. 16 shows a case where the third embodiment is applied to a performance operation performed at the same timing as in FIG. In FIGS. 16 and 15, the non-playing time (the non-tone control time in the case of FIG. 16)
Is started, and when the non-performance time (non-tone control time) exceeds a predetermined time, the performance time is stopped in the same manner in both embodiments. However, at the timing of ', all the tone controls have been completed, so in the case of the third embodiment shown in FIG. 16, the non-tone control time is counted from the point', and the non-tone control time is At a timing 'exceeding a predetermined time', the performance time is stopped, and the timing of the performance time is restarted at the timing of the next key release '.
The state up to the key release ′ is a case where five keys are depressed in the area a as described above, and one key is kept depressed but not released. Therefore, in the case of the third embodiment (FIG. 16), the state where the remaining one key is kept depressed,
In other words, even when the performance is continued, 'and'
The time between them is not counted as the performance time, and this causes an error in the direction of shortening the performance time.

On the other hand, in the fourth embodiment (FIG. 15), when five keys are depressed in the time area a and one key is kept depressed and not released. Does not time the non-performance time ', and of course does not stop timing the performance time. Therefore, even when the performance from the key depression to the key release is long, the actual performance time can be measured without error, and the performance time without error is displayed on the display unit 11. be able to.

[0038]

As described above, according to the present invention, the performance time is started by the first performance operation after the power is turned on, and when the performance operation interval becomes a predetermined value or more, the performance time is stopped. At the same time, the stopped performance time is restarted when the next performance operation is performed. Therefore, the actual performance time can be accurately measured without the loss time from the power-on to the start of the performance and the break time during which the performance is temporarily stopped being counted as the performance time.

When the non-operation time of the tone signal control means exceeds a predetermined value, the timing of the performance time is stopped, so that the performance is performed while generating a tone in which the envelope attenuates slowly. In this case, even if the performance operation interval becomes longer, the timing of the performance time does not stop. Therefore, even when the performance is performed while generating a musical tone whose envelope slowly decreases, the actual performance time can be accurately measured.

Further, when the performance operation means is in the non-operation state and the tone signal control means is in the non-operation state for a time equal to or more than a predetermined value, the timing of the performance time is stopped. Therefore, even when the tone control is completed during the time from when the key is pressed to when the key is released, the timing of the performance time does not stop during the key is pressed. Therefore, the actual performance time can be accurately measured even when the performance is performed in a performance mode in which the time from the key depression to the key release is long and the tone control can be completed during that time.

In addition, by displaying these timed performance times, it is possible for the player to know the exact performance time, and since the predetermined value can be variably set, a long pause is provided. If a rest with a note length is included, a large value is set as a predetermined value in accordance with this, so that the performance time is stopped and timed when the part corresponding to the rest is played. It is possible to prevent an inconvenience that an error occurs in the performance time.
