Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power-off warning device and a method for playing a predetermined melody and prompting the user to stop the power supply when an operation of a switch or the like on an electric or electronic device such as an electronic musical instrument is not performed for a predetermined time or more. And a storage medium.

[0002]

2. Description of the Related Art In recent years, some electric or electronic devices such as electronic musical instruments require an operator to operate various switches or keyboards within a certain period of time in order to prevent forgetting to turn off a power switch. Some devices have an auto power-off function that automatically stops supplying power when the power is not added.

[0003]

The auto power-off function is limited to the one using a soft power switch that can be turned off by software control. Therefore,
There is a problem that an auto power-off function cannot be applied to a device of a type in which power is supplied by a hardware power switch. Some devices have a hardware-like mechanism for turning off the power switch itself. However, in this case, the hardware configuration is complicated and expensive, and thus cannot be adopted. Therefore, in the case of a device having a hardware power switch, when various switches are not operated within a certain period of time, a warning sound such as "beep" is sounded to inform the operator that the power switch has been forgotten to be turned off. There is something. However, there is a problem that the operator may miss the sound only with the normal warning sound, which is not very effective. Also, if the volume itself is set low,
There is also a problem that since the warning sound itself is emitted at a low volume, it does not make sense as the warning sound.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has a power-off warning device and a power-off warning device that can surely recognize an operator's forgetting to turn off a power switch when a switch or the like has not been operated for a predetermined time or more. It is an object to provide a method as well as a storage medium.

[0005]

A power-off warning device according to the present invention detects that no operation of a switch or the like has been performed for a predetermined time or more, and generates music for power-off warning in response to the detection. is there. By generating predetermined music as a warning sound in this way, it is possible to make the operator surely recognize that he has forgotten to turn off the power.

[0006] If it is detected that the switch or the like has not been operated for a predetermined time after the music for warning of turning off the power is generated, music in a mode different from the previous music is generated. You may. By generating the music for warning of turning off in a manner different from the last time, it is possible to make the operator surely recognize the turning off. Note that this different aspect may be realized by making at least one of the number of music performance parts, the performance time, the volume, and the tempo different.

[0007] When it is detected that no operation of the switch or the like has been performed for a predetermined time shorter than the predetermined time after generating the music for warning of power-off warning, music for warning of power-off warning is also provided. May be generated again. Accordingly, when the time period during which the switch or the like is not operated is long, not only the warning music is repeatedly generated, but also the time interval at which the warning music is generated becomes shorter than the previous time (that is, the warning music is gradually reduced at the time interval). Is repeated), so that the sense of urgency gradually increases, so that the operator can more reliably recognize that the user has forgotten to turn off the power. In this case, the mode of each repeated warning music may be different from the previous mode as described above. Then, it is possible to make the operator more surely recognize that the user has forgotten to turn off the power.

Further, when music for the power-off warning is generated, the warning music is generated in a setting state different from the setting state of the predetermined parameter before the generation of the warning music. Accordingly, the setting of the predetermined parameter before the generation of the warning music may be returned.
In other words, after the warning music is generated with its own parameters, by returning to the original setting state, it is possible to immediately continue the operation in the original setting state.

The present invention can be constructed and implemented not only as a device invention, but also as a method invention.
Can be implemented. Further, the present invention can be implemented in the form of a computer program, and can also be implemented in the form of a recording medium storing such a computer program. That is, the method according to the present invention is a method for warning that the user has forgotten to turn off the power in an electric or electronic device including operation means such as a switch, and detecting that the operation of the switch or the like has not been performed for a predetermined time or more. Generating a music for warning to forget to turn off the power supply according to the detection. If it is further detected that the operation of the switch or the like has not been performed for a predetermined period of time after generating the music for warning of turning off the power, a step of generating music in a mode different from the previous music may be further provided. .

A storage medium according to the present invention is a machine-readable storage medium storing a processing program for warning that the user has forgotten to turn off the power in an electric or electronic device having an operation means such as a switch. The program includes a procedure for performing a process for detecting that the operation of the switch or the like has not been performed for a predetermined time or more, and a procedure for performing a process for generating music for warning of a power-off warning according to the detection. It is equipped. By reading and executing the program stored in the storage medium by a computer built in an electric or electronic device, the same function of generating a music for warning when the power is forgotten to be turned off can be realized. If the program further detects that the switch or the like has not been operated for a predetermined time or more after generating the music for warning of turning off the power, the program further includes a step of generating music in a mode different from the previous music. You may have.

A CD-ROM may be used as one of the removable external storage media. The CD-ROM may store various data such as automatic performance data, chord progression data, musical sound waveform data, and video data, and an arbitrary operation program.
The operation programs and various data stored in the CD-ROM can be read out by the CD-ROM drive 26 and transferred to and stored in the hard disk device 25. This makes it possible to easily perform new installation and version upgrade of the operation program.

The communication interface 27 is connected to a data and address bus 2M, and can be connected to various communication networks 28 such as a LAN (local area network), the Internet, and a telephone line via the communication interface 27. May be exchanged with the server computer 29. Thus, when the operation program and various data are not stored in the hard disk device 25, the operation program and various data can be downloaded from the server computer 29. In this case, a command for requesting downloading of an operation program and various data is transmitted from the automatic performance device, which is a musical sound generation device serving as a client, to the server computer 29 via the communication interface 27 and the communication network 28. The server computer 29 transmits predetermined operation programs and data to the automatic performance device via the communication network 28 in response to the command. The automatic performance device receives these operation programs and data via the communication interface 27 and stores these programs and data in the hard disk device 25. Thus, the download of the operation program and various data is completed.

The keyboard 2C is provided with a plurality of keys for selecting the pitch of a musical tone to be produced, and has key switches corresponding to the respective keys. It has touch detection means. The keyboard 2C is a basic operator for music performance, and it goes without saying that other keyboard operators may be used. The key press detection circuit 2D includes a key switch circuit provided corresponding to each key of the keyboard 2C for designating the pitch of a musical tone to be generated. The key press detection circuit 2D detects a change in the key 2C from the key release state to the key press state, and outputs a key-on event.
A key-off event is output by detecting a change from a key-depressed state to a key-released state, and a note number indicating a key pitch of each key-on event and key-off event is output. In addition, the key press detection circuit 2D discriminates a key press operation speed, a key press force, and the like when a key is pressed, and outputs velocity data and after touch data.

The switch detection circuit 2F includes various switches 2E
It is provided corresponding to each of the above switch groups, and outputs a switch event corresponding to the operation state of each of these switch groups to the CPU 21 via the data and address bus 2M. The various switches 2E include a power switch, an automatic performance start / stop switch, a pause (pause) switch, and various hardware switches (mechanical switches) for selecting, setting, and controlling the tone, volume, effect, and the like. It is a thing. The display circuit 2H displays various information such as the control state of the CPU 21 and the contents of the setting data on the display 2G. The display 2G is composed of a liquid crystal display panel (LCD) or the like, and its display operation is controlled by the display circuit 2H.

The tone generator 2J can generate tone signals simultaneously on a plurality of channels, and inputs tone control information (MIDI data such as note-on, note-off, velocity, pitch, tone number, etc.) given from the CPU 21. And
A tone signal is generated based on these data. In the tone generator circuit 2J, a tone signal can be simultaneously generated on a plurality of channels by using one circuit in a time-division manner to form a plurality of tone channels, or one tone channel is constituted by one circuit. It may be of the type as described below. Also, any tone signal generation method in the tone generator circuit 2J may be used. For example, a memory reading method (waveform memory method) for sequentially reading out tone waveform sample value data stored in a waveform memory in accordance with address data that changes in accordance with a pitch of a musical tone to be generated, or a phase angle parameter An FM method for executing a predetermined frequency modulation operation as data to obtain tone waveform sample value data, or an AM method for executing a predetermined amplitude modulation operation using the address data as phase angle parameter data to obtain tone waveform sample value data, or the like. May be appropriately adopted. In addition to these methods, a physical model method that synthesizes a musical sound waveform by an algorithm that simulates the sounding principle of a natural musical instrument, a harmonic synthesis method that synthesizes a musical sound waveform by adding a plurality of harmonics to a fundamental wave, A formant synthesis method of synthesizing a musical tone waveform using a formant waveform having a specific spectral distribution, an analog synthesizer method using VCO, VCF, and VCA may be employed. In addition, the tone generator circuit is not limited to the one that uses the dedicated hardware, and the tone generator circuit may be configured using a DSP and a microprogram. Alternatively, the tone generator circuit may be configured using a CPU and a software program. It may be.

The timer 2N generates a tempo clock pulse for counting a time interval, setting a tempo of automatic accompaniment, and a clock pulse for effectively operating a predetermined function. In this embodiment, the timer 2N is set to C
A timer interrupt signal is output to the PU 21 every second as a clock pulse for operating the power-off warning device. The effect circuit 2K gives various effects to the tone signal from the tone generator 2J, and outputs the tone signal with the effect to the sound system 2L. The tone signal to which the effect is given by the effect circuit 2K is generated through a sound system 2L including an amplifier and a speaker.

Next, an example of keyboard / switch (other than power supply) processing performed in response to an event when a switch other than the power switch among the keys of the keyboard 2C and the various switches 2E is operated is shown in FIG. This will be described with reference to a flowchart. When a switch other than the power switch among the keys of the keyboard 2C and the various switches 2E is operated, an event corresponding to the operation occurs, and a function corresponding to the event is executed. For example, in the case of a key-on event, a sound is generated correspondingly, in the case of a key-off event, the corresponding sound is muted, or when an automatic performance start / stop switch is operated, the corresponding sound is generated. Starts and stops the automatic performance processing, temporarily stops the automatic performance processing when the pause (pause) switch is operated, and selects, sets, and controls the tone, volume, and effect. When the switch is operated, the corresponding function is executed. Then, the value of the timer counter that measures the time during which the keyboard 2C and various switches 2E are not operated is cleared to “0”. In addition, keyboard 2
The value of the number-of-warnings counter indicating how many times the warning has been issued since the C and various switches 2E are no longer operated is also cleared to "0", and the routine returns. As a result, each time the keyboard 2C or various switches 2E are operated, the values of the timer counter and the warning counter are cleared to "0".

FIG. 4 is a diagram showing an example of a timer interrupt process executed in synchronization with the operation clock (period of about 1 second) from the timer 2N. In this timer interrupt processing, first, at step 41, a time counter value for measuring a predetermined time is incremented. Then, in steps 42 and 43, the value of the number-of-warnings counter is determined, and the process branches to processing according to the determination result. If the number-of-warnings counter value is "0", the process proceeds to step 44,
If the value is "1", the process proceeds to step 49, and if the value is larger than "1", the process proceeds to step 4F. In step 44,
It is determined whether or not the timer counter value is equal to the predetermined value T1. If the timer counter value is equal, the processing of steps 45 to 48 is performed. If the timer counter value is smaller than the predetermined value T1, the process returns. In step 45, the volume is set to a value that is higher than the current set volume by a predetermined volume value VOL1. In step 46, only the reproduction of the melody part in the first section of the warning melody is started. By the start of the reproduction, the warning performance processing of FIG. 5 is executed, and a warning melody is generated. At step 47, the timer counter value is cleared to "0". Then, in step 48, the value of the number-of-warnings counter is incremented. That is, at this point, the warning counter value becomes "1".

Steps 49 to 4E are performed when the number-of-warnings counter value is "1". That is, after the processing of steps 45 to 48 described above is performed and the warning melody is generated, the processing is performed when the power switch is not turned off and no switches other than the keyboard and the power switch are operated. Things. First, in step 49, it is determined whether or not the timer counter value is equal to the predetermined value T2. If the timer counter value is equal, the processing of steps 4A to 4E is performed. If the timer counter value is smaller than the predetermined value T2, the process returns. Here, the predetermined value T2 is a value smaller than the predetermined value T1 used in the determination of step 44. by this,
The warning melody is generated in a shorter time than the time when the sounding of the previous warning melody was started. Step 4A
Then, the volume is set to a predetermined volume value VOL2 higher than the current set volume.
And set it to a larger value. Here, the predetermined volume value VOL2
Is a value larger than the predetermined volume value VOL1 of step 45. Thus, even if the operator does not notice the volume of the previous warning melody, a warning melody is generated at a large volume this time, so that the operator can be surely recognized to forget to turn off the power. . In step 4B, the tempo of the warning performance is set to a value faster by a predetermined tempo value TP1 than the current set tempo value. When the tempo of the warning melody is faster than that of the previous melody, attention to the operator can be more surely called. In step 4C, reproduction of two parts of the melody part and the rhythm part in the first and second sections of the warning melody is started. As described above, the sounds of the melody part and the rhythm part are generated over a section longer than the generation of the warning melody in the previous time, so that it is possible to more reliably recognize that the power has been forgotten to be turned off. By starting the reproduction, the warning performance processing of FIG. 5 is executed. In step 4D, the timer counter value is cleared to "0". Then, in step 4E, the number-of-warnings counter value is incremented. That is, at this time, the warning number counter value becomes “2”.

The processes of steps 4F to 4K are performed when the number-of-warnings counter value is "2" or more. That is, the processing in steps 4A to 4E described above is performed, and the processing is performed when a keyboard or switches are not operated. First, in step 4F, it is determined whether or not the timer counter value is equal to a predetermined value T3. If the timer counter value is equal, steps 4G to 4K are performed. If the timer counter value is smaller than the predetermined value T3, the process returns. Here, the predetermined value T3 is set in step 4
The value is smaller than the predetermined value T2 used in the determination of No. 9. As a result, the warning melody is generated in a cycle shorter than the sounding start time of the previous warning melody.
In step 4G, the maximum value Vm of the volume that can be set
Set to ax. In step 4H, the tempo of the warning performance is set to a value such that the tempo is faster by a predetermined tempo value TP2 than the current set tempo value. Here, the predetermined tempo value TP2 is the predetermined tempo value T used in step 4B.
This is a value that makes the tempo faster than P1. In step 4J, the melody part,
Start playback of all parts of the rhythm part and the chord base part. In this way, the tempo is fast, the volume is maximum, the performance section is long, and the warning melody is generated for all the performance parts, so that the operator can be surely recognized to forget to turn off the power. By starting the reproduction, the warning performance processing of FIG. 5 is executed. In step 4K, the timer counter value is cleared to "0". Here, step 4
Although the increment of the number-of-warnings counter value as in step 8 and step 4E is not performed, it goes without saying that it may be performed.

FIG. 5 shows steps 46 and 4C of FIG.
FIG. 11 is a diagram illustrating an example of a warning performance process executed when a warning performance start event occurs by the process of step 4J. In this warning performance processing, the automatic performance data of the performance part and performance section designated in step 51 is reproduced. That is, in the case of the warning performance start event in step 46, the melody part is reproduced only for the automatic performance data in the first section. In the case of step 4C, the first of two parts, the melody part and the rhythm part
And only the automatic performance data of the second section is reproduced.
In the case of step 4J, the automatic performance data for all the parts is reproduced for all the sections. In step 52, it is determined whether or not the reproduction of the predetermined automatic performance data has been completed. The reproduction processing of the automatic performance data in step 51 is performed until the reproduction processing is completed. Is returned to the original set value, and in step 54, the tempo is returned to the original set value. That is, a process of returning the values of the volume and the tempo set in each step of FIG. 4 to the original set values is performed. As a result, when the electronic musical instrument or the like is to be operated continuously after the end of the warning performance, the previous set value can be effectively taken over.

Next, the operation of the power-off warning device according to this embodiment will be described with reference to the conceptual diagram of FIG. FIG.
, The horizontal axis indicates time, and the keyboard 2C near the left end
The operation of the upper key and various switches 2E is indicated by arrows. In the figure, four types of key events or switch events have occurred. Then, a case is shown in which no event has occurred since the last event occurred.
First, at the time of the last event, the timer counter value and the number-of-warnings counter value are cleared to "0".
The timer count value is incremented by one.
At this time, since the number-of-warnings counter value is “0”, the determination in step 44 is performed via step 42. At this time, since the determination result of step 44 is NO, the processing of step 41, step 42, and step 44 is repeatedly executed. Then, the timer counter value becomes a predetermined value T1.
At this point, by the processing of steps 45 and 46, as shown in FIG. 1, only the melody part of the first section of the warning performance is reproduced at a normal tempo with a slightly higher volume sound. Then, in steps 47 and 48, the timer counter value is cleared to "0",
The warning counter value is set to "1".

Then, the processes of steps 41 to 43 and step 49 are repeatedly executed until the timer counter value reaches the predetermined value T2. Then, when the timer counter value reaches the predetermined value T2, step 4A,
By the processing of steps 4B and 4C, as shown in FIG. 1, the melody part and the rhythm part of the first and second sections of the warning performance are reproduced with a considerably high volume and a slightly high tempo. Then, in steps 4D and 4E, the timer counter value is cleared to "0", and the warning counter value is set to "2". Then, until the timer counter value reaches the predetermined value T3,
Steps 41 to 43 and step 4F are repeatedly executed. Then, when the timer counter value reaches the predetermined value T3, the processing of steps 4G and 4H causes all parts (melody) of all sections (first, second and third sections) of the warning performance as shown in FIG. part,
For the rhythm part and the chord base part), the reproduction process is performed at the maximum volume and at a considerably higher tempo. Then, in step 4K, the timer counter value is cleared to "0". Thereafter, when the timer value reaches the predetermined value T3, the warning performance is repeated for all sections and all parts. Thus, it is possible to reliably notify the operator that the power switch is not turned off.

In the above-described embodiment, the case where the automatic performance data is reproduced as the warning music has been described. However, the waveform data of the music itself may be stored and reproduced. Further, the warning music may be shared with data used for demonstration, performance practice, and the like. In the above-described embodiment, the case where the volume, the tempo, the number of performance parts, the number of performance sections, and the performance time interval change at each repetition has been described as an example. Alternatively, any combination may be changed. Also, the tune of the warning music may be changed each time it is repeated. Further, a sound may be generated instead of the warning music. Further, the warning music and the voice may be appropriately combined.

In the above-described embodiment, an electronic musical instrument has been described as an example. However, the present invention is not limited to this, and can be applied to other appropriate electric or electronic equipment such as a karaoke apparatus (for example, a handy type). Further, the present invention can also be applied to an electronic musical instrument configured by a combination of a personal computer and application software. This application software may be stored in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory and supplied to a personal computer, or may be supplied via a network. Further, the storage medium storing the program according to the present invention is not limited to a removable medium, but may be a built-in one in required electric or electronic equipment. In the case of an electronic musical instrument, the present invention is not limited to the keyboard instrument as in the embodiment, but may be a stringed instrument type, a wind instrument type, a percussion instrument type, or the like. Further, the present invention is not limited to an electronic musical instrument having a built-in sound source device, automatic performance device, and the like, but may be configured as separate devices and connected to each other using communication means such as MIDI or various networks. It goes without saying that the present invention may be applied to an automatic performance piano. In the above embodiment, the performance data format and the like are not mentioned, but the performance data format is
"Event + relative time (delta time)", which represents the performance event occurrence time as the time from the previous event, "event + absolute time", which represents the performance event occurrence time as the absolute time in a song or bar , "Pitch (rest)", which represents performance data in note pitch and note length or rest and rest length
+ Note length "or a so-called" solid system "in which a memory area is secured for each minimum resolution of performance and the performance event is stored in a memory area corresponding to the time when the performance event occurs.
It goes without saying that it may be configured in any form.

As a method of controlling the tempo of the automatic performance, a method of changing a processing cycle (namely, a cycle of a tempo clock) or a method of correcting a timing data value such as a delta time while keeping the tempo clock cycle unchanged. It goes without saying that various methods may be used, such as a method for changing the value for counting the timing data in one process. The automatic performance data may have a format in which data of a plurality of channels are mixed, or may have a format in which data of each channel is divided for each track.
