DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metronome.

Conventionally known metronomes have a beat and tempo adjustment mechanism. For example, if the metronome is set to four beats, it is called "ki, ka, ka, ka, ki, ka, ka, ka, ka". ... ”, The timing is notified by changing the characteristics of a strong beat (expressed by the pronunciation of a kick) and a weak beat (expressed by the pronunciation of a ka). Note that, in general, a strong beat uses a more stimulating sound than a weak beat. The stimulating sound has a higher pitch, contains many harmonics, has a large volume, or a combination thereof.

[0003] However, in the conventional metronome, when the tempo is slowed down, there is a problem that the interval between beats is prolonged, and it is difficult to grasp an accurate timing. Further, there is a problem that it cannot cope with a shuffle system or a case where 6/8 is counted as two beats.

[0004] The present invention has been made in view of such problems, and a metronome that can easily grasp the correct timing even when the tempo slows down and can cope with various special patterns of music. Intended to provide

[0005]

In order to solve the above-mentioned problems, a metronome according to the present invention comprises, as one mode, tempo setting means for setting a tempo, time setting means for setting a time signature, and time setting. A back beat setting means for setting the timing of the back beat between all the beats of the beat set by the means, and a strong beat state at the timing of the strong beat of the beat set by the beat setting means, and A beat state notifying means for notifying the weak beat state at the timing and notifying the back beat state at the back beat timing set by the back beat setting means. In this metronome, by setting the back beat by the back beat setting means, the timing between normal beats can also be notified by the back beat, and even if the interval between beats is prolonged, accurate timing can be grasped .

According to another aspect of the metronome of the present invention, there are provided a tempo setting means for setting a tempo, a time setting means for setting a time signature, and a predetermined one of beats of the time set by the time setting means. A beat changing means that changes the weak beat of the timing to a back beat, and a strong beat state is reported at the timing of the strong beat of the beat set by the beat setting means, a weak beat state is reported at the timing of the weak beat, and the beat is changed Beat state notifying means for notifying the back beat state at the timing of the back beat changed from the weak beat by the means. In this metronome, by changing a normal weak beat to a back beat by the beat changing means, it is possible to generate various forms of metronome sounds and the like that can cope with the case where 6/8 is counted as 2 beats.

In another form, the metronome according to the present invention comprises a tempo setting means for setting a tempo, a time setting means for setting a time signature, and a time interval between all the beats set by the time setting means. Back beat setting means for setting the timing of the back beat, beat changing means for changing the weak beat at a predetermined timing among the beats of the beat set by the beat setting means to the back beat, and the beat set by the beat setting means The strong beat state is reported at the timing of the strong beat of the time signature, the weak beat state is reported at the timing of the weak beat, the back beat set by the back beat setting means or the back beat changed from the weak beat by the beat changing means. A beat state notifying means for notifying a back beat state at a timing is provided, and the back beat setting means and the beat changing means comprise a single operating means, and this operating means has a back beat setting on one side from a predetermined operation setting position. Means, the other side is the parameter of the beat change means Configured to set the data. In this metronome, by operating a single operating means, the timing of the back beat can be set between all the beats of the time set by the time setting means, or the predetermined timing of the beat of the time can be weakened. By changing the beat to a back beat, it is possible to easily generate various types of metronome sounds and the like that can cope with special music and the like.

In another embodiment, the metronome according to the present invention further comprises, in each of the above-mentioned metronomes, a notification back beat setting means for setting which of the back beats the back beat is to be notified of. With respect to the back beat notification, the beat state notifying means is configured to notify only the back beat set by the notification back beat setting means. In this metronome,
Since the back beat that informs the back beat and the back beat that does not report the back beat can be arbitrarily set, it is possible to easily generate various types of metronome sounds and the like that can also respond to special music and the like.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a block configuration of a metronome as one embodiment of the present invention. In FIG. 2, reference numeral 3 denotes a CPU (central processing unit) for controlling the entire apparatus, and 4 denotes a memory, which comprises a ROM and a working RAM. The ROM stores control programs and various data. Various register values and parameter values are stored. 1 is an operator group, 2 is an operator detector, and the setting state of the operator group 1 detected by the operator detector 2 is CP.
It is sent to U3 for processing. Reference numeral 5 denotes a display circuit, which displays parameter values and the like set by the operators on a display unit. 6
Is a sound source, and emits a metronome sound such as a strong beat, a weak beat, and a back beat through the speaker 7.

FIG. 3 shows a detailed configuration of the operator group 1. In the figure, reference numeral 11 denotes a beat setting dial. By turning the beat setting dial 11, an arbitrary beat (beat) from "2 to 16" can be set. Reference numeral 12 denotes a tempo setting dial. By turning the tempo setting dial 12, an arbitrary tempo value can be set.
The set tempo value is displayed on the display unit 50 of the display circuit 5. This tempo value is expressed by the number of beats played per minute. With the beat setting dial 11 and the tempo setting dial 12, a beat value and a tempo value of a normal metronome sound can be set.

Reference numeral 13 denotes a resolution switch for setting each value of a sub-beat (back beat) or each value of a reduction (about a minute) by sliding a knob of the resolution switch 13. In this example, there are three values of "1/2, 1/3, 1/4" as subbeats, four values of "2, 3, 4, 5" as reduction, and the knob is set to "1". If so, it will be a conventional normal metronome. The details of the subbeat and the reduction will be described later.

Reference numeral 14 denotes a subbeat selection switch, which can be switched to six values of "OFF, 1, 2, 3, 4, ALL" by sliding a knob of the subbeat selection switch 14. This sub beat selection switch 1
Reference numeral 4 denotes a switch for selecting which of the back beats to be sounded, which will be described later in detail.

Reference numeral 15 denotes a strong beat switch for setting whether or not to generate a strong beat, and 16 denotes a weak beat switch for setting whether or not to generate a weak beat. When set to “ON”, the corresponding beat is pronounced, and when pushed back to “OFF”, the corresponding beat is stopped. Reference numeral 17 denotes a display by printing, so that the contents of the subbeat selection switch 14, the strong beat switch 15, and the weak beat switch 16 can be easily visually identified.

Next, the basic operation of the above-described embodiment will be described with reference to FIG. In FIG. 1, a circle represents a strong beat, a large circle represents a weak beat, and a small circle represents a back beat. FIG.
(A), the resolution switch 13 is set to “1”, and the strong beat switch 15 and the weak beat switch 16 are set to “OF”.
F ”, the sub beat selection switch 14 is set to“ ALL ”, and the beat setting dial 11 is used to set“ 4 ”beats.
The sound of each beat when "120" is selected with the tempo setting dial 12 is shown. In this case, the strong beat sound and the weak beat sound are each pronounced as "ki, ka, ka, ka, ki, ka ...", and become a normal metronome sound.

FIG. 1B shows a case where the resolution switch 13 is set to "1/2" in the state of FIG. 1A. In this case, a back beat (expressed by a Ko sound) is inserted between each beat (a strong beat and a weak beat). "1/2" means that the back beat sound is placed at the center of each beat (that is, at the 1/2 position). Therefore, the metronome sound in this case is "Ki, Ko, Ka, Ko, Ka, Ko, Ka, Ko,
Ki, Ko, Ka ... " Of course, the sounding timing of each of the strong beat and the weak beat does not change, and the back beat is included in the task between them.

FIG. 1C shows a case where the sub-beat selection switch 14 is set to "1/4" in the state of FIG. 1A. In this case, a back beat is input at a timing obtained by equally dividing each beat (strong beat and weak beat) into four. "1/4" means that a back beat sound is inserted at equal intervals of 1/4 between each beat. Therefore, the metronome sound in this case is "Kit,
Ko, Ko, Ko, Ka, Ko, Ko, Ko, Ka, Ko, Ko, Ko, Ka, Ko, Ko, Ko, Ki, Ko, Ko, Ko, Ko ... " As described above, the subbeat value of the resolution switch 13 is a parameter for setting at what intervals the backbeat is inserted between each of the strong beat and the weak beat.

FIG. 1D shows a case where the sub-beat selection switch 14 is set to "3" in the state of FIG. 1C. In this case, the third of the back beats inserted between each beat
Only beats are pronounced. Therefore, the metronome sound in this case is "Ki,-,-, Ko, Ka,-,-, Ko, Ka,-,-, Ko, Ka,-,-, Ko, Ki,
(-Indicates no sound), which is a so-called shuffle-type metronome sound. As described above, the value selected by the sub-beat selection switch 14 is a parameter for setting the number of the first beat of the back beat inserted between beats for “1, 2, 3, 4”. And "OFF" does not sound all, but "A"
"LL" is a parameter for setting all sounds.

FIG. 1E shows the case where the resolution switch 13 is set to the reduction "2" in the state of FIG. 1A. This reduction "2" means that only a multiple of 2 of the weak beats of the current beat set by the beat setting dial 11 is pronounced with a weak beat and the other weak beats are changed into back beats. Instruct. Therefore, since there are currently four beats, setting the reduction to “2” will cause the first and third beats, which were weak beats, to be changed from weak beats to back beats, and the metronome sound will be pronounced. "Ki,
Ko, Ka, Ko, Ki, Ko ... "

FIG. 1 (f) shows a case where the resolution switch 13 is set to the reduction "3" in the state of FIG. 1 (a). This reduction "3" indicates that only the multiple of the weak beats of the current beat is pronounced with a weak beat and the other weak beats are changed to back beats. Therefore, since the current beat is 4 beats, the first and second beats, which were weak beats by setting the reduction to “3”, are changed from weak beats to back beats, and the metronome sound is changed to “3”. Ki, Ko, Ko, Ka, Ki, Ko ... "

The above operation is a basic operation. In addition, FIG. 4 shows a beat setting dial 1 corresponding to various uses.
1, the setting mode of the resolution switch 13, the subbeat selection switch 14, and the weak beat switch 16 is shown. In the figure,
(A) is a 6/8 system, (b) is a 12/8 system, (c) is a shuffle system, (d) is a 4/4 subbeat, and (e) is 4/4.
Subbeat only (ie, weak beat switch 16 "OFF")
Stops the weak beat), and (f) shows only 16 back beats.
(G) to (h) are metronome sounds of special musical tones.

Next, a processing procedure in the CPU 3 for performing the above operation will be described with reference to the flowcharts of FIGS. FIG. 5 is a read processing routine for reading the state of the operator group 1, and FIG. 6 is a timer interrupt routine for generating a metronome sound at each timing. This timer interrupt routine is an interrupt generation interval set in the read routine. Fired every time.

First, various registers and the like used in these flowcharts will be described. The following are the switch read registers. "Beats": a register for storing the set value of the beat setting dial 11 "Reso": a register for storing the set value of the resolution switch 13 "Sel": a register "1 to 4" for storing the set value of the subbeat select switch 14 "OFF" = 0, "ALL" =-
It becomes 1. “St”: Register for storing the setting state of the strong beat switch 15 “ON” = 1, “OFF” = 0 are set. "Wk": Register for storing the setting state of the weak beat switch 16 "ON" = 1, "OFF" = 0. "Tmp": Register unit (count / minute) for storing the set value of the tempo setting dial 12. The following counters are also available. “Cs”: a strong beat counter that counts the timing of strong beats “Cw”: a weak beat counter that counts the timing of weak beats The following arithmetic registers are available. "NSt": Register for storing the maximum value MAX of the strong beat counter "nWk": Register for storing the maximum value MAX of the weak beat counter "nInt": Interrupt generation interval (sec)

The reading routine of FIG. 5 is started periodically from a main routine (not shown). First, the state of the operator group 1 is read (step S1), and it is determined whether or not there is a state change in the operator group 1 (step S2). If there is no state change, the process returns to the main routine. If there is a state change, it is determined whether the value set by the resolution switch 13 at that time is 1 or less. If the resolution switch 13 is 1 or less, the normal state (= 1) or subbeat is set, and if it is above 1, the reduction is set.

Set value of resolution switch 13 ≦ 1
If it is (normal state or subbeat setting state), the next parameter is set (step S5). “NSt” ← “Beats” × (1 / “Reso”) “nWk” ← 1 / “Reso” “nInt” ← (60 / “Tmp”) ÷ (1 / “Reso”
”)

Then, the strong beat counter maximum value register "n"
Set “Beats” × (1 / “Reso”) to “St.” That is, the number obtained by equally dividing one bar (interval between a strong beat and a strong beat) by a weak beat and a back beat is the maximum value of a strong beat counter. "NSt" is used to set the maximum value of the weak beat counter "nWk" to the number obtained by equally dividing the interval of weak beats by the back beat, and "interrupt generation interval" nInt "for starting the routine of FIG. I do.
This means that the period (minute unit) between beats (strong beat and weak beat) is calculated by (1 / “Tmp”), multiplied by 60 and converted to seconds, and the result is further converted to (1 / “ Reso ”) to convert into an interval of the back beat set by the resolution switch 13 to obtain an interrupt generation interval“ nInt ”. By this setting, fine sub-bee (back beat)
An interrupt occurs at the timing of.

On the other hand, if the setting value of the resolution switch 13> 1 (that is, the reduction setting state), the next parameter is set (step S4). “NSt” ← “Beats” “nWk” ← “Reso” “nInt” ← (60 / “Tmp”)

Then, the strong beat counter maximum value register "n"
The beat value “Beats” set by the beat setting dial 11 is set to “St”. This is, for example, as shown in FIG. 1E, one bar is equally divided into a weak beat and a back beat (changed from a weak beat). Then, the divisor "Reso" set by the resolution switch 13 is set in the weak beat counter maximum value register "nWk".
In (e), this corresponds to a number obtained by equally dividing the weak beat and the strong beat by the back beat (changed from the weak beat). In the interrupt generation interval register "nInt", the period (minute unit) between beats (strong beat and weak beat) is calculated by (1 / "Tmp"), and this is multiplied by 60 and converted to seconds. Set. With this setting, an interrupt occurs at a normal beat (an interval between weak beats).

When these settings are completed, the process returns to the main routine. 5 by means of a timer (not shown).
Interrupt generation interval "nInn" set in the read routine of
The timer interrupt routine shown in Fig. 6 is started at every interrupt occurrence interval "nInt." In this timer interrupt routine, it is determined whether the timing of the strong beat, the weak beat, and the back beat at the time of the timer interrupt. A check is performed to generate a respective metronome sound at each timing, and this operation will be described below with reference to Fig. 7. Fig. 7 shows the transition state of the strong beat counter "Cs" and the weak beat counter "Cw". In this example, the beat setting dial 11 sets the beat value to “5” and the resolution switch 13 sets the reduction to “2”. In this case, the strong beat counter Maximum value register “nSt” =
“5”, weak beat counter maximum value register “nWk” =
“2” is set.

When the timer interrupt routine is started, first, the strong beat counter "Cs" and the weak beat counter "Cw" are updated. That is, “Cs” ← “Cs” +1 “Cw” ← “Cw” +1 is incremented by one (step S11).

Next, it is determined whether or not the updated value of the strong beat counter "Cs" has reached the value of the strong beat counter maximum value register "nSt" (step S12). If it has reached (ie, “Cs” = “nSt”), the strong beat counter “Cs” and the weak beat counter “Cw” are set (ie, reset) to “Cs” ← 0 and “Cw” ← 0. (Step S3). In the example of FIG. 7, "5" indicating the fifth beat is set in the strong beat counter maximum value register "nSt", and the strong beat counter "Cs" is sequentially incremented to reach this value. A state is shown in which both the beat counter "Cs" and the weak beat counter "Cw" are reset.

Next, by checking the state of the strong beat switch register "St", the strong beat switch 15 is set to "ON" or "OF".
F "(step S14), and if" ON ", a strong beat (ki) is generated (step S15), and" OF "
If "F", the process returns from the timer interrupt routine without generating a strong beat. By this processing, a strong beat sound is generated at the timing of each strong beat.

If the updated value of the strong beat counter "Cs" has not reached the strong beat counter maximum value register "nSt" (step S12), then the value of the weak beat counter "Cw" is changed to the maximum value of the weak beat counter. It is determined whether or not the register “nWk” has been reached, that is, whether or not the current interrupt timing is the timing of generating a weak beat (step S16). If the timing is a weak beat sound, the reset is performed by setting "0" to the weak beat counter "Cw" (step S1).
7). In the example of FIG. 7, the weak beat counter maximum value register “n”
Wk "=" 2 ", so that every two beats, the weak beat counter" C
w "is reset.

Next, by checking the state of the weak beat switch register "Wk", the weak beat switch 16 is set to "ON" or "OF".
F ”(step S18), and if“ ON ”, a weak beat is generated (step S19).
If "F", the process returns from the timer interrupt routine without generating a weak beat. With this processing, a weak beat sound is generated at each weak beat timing.

On the other hand, if the value of the weak beat counter "Cw" has not reached the weak beat counter maximum value register "nWk" (step S16), the setting state of the sub beat selection switch 14 is determined by referring to the value of the register "Sel". I do. If the register “Sel” = “− 1”, that is, if the sub-beat select switch 14 is “ALL”, all back beats are generated.
A back beat is generated (step S21). Register "Se
l ”is one of“ 1 to 4 ”, the register“ Se ”
It is determined whether or not the weak beat counter “Cw” matches the value of “l” (step S22), and a backbeat is generated only when the counter value matches (step S21).
“0”, that is, the sub beat selection switch 14
If it is "F", no backbeat is generated. By the above processing, the back beat can be generated.

In implementing the present invention, various modifications are possible. For example, in the above-described embodiment, the timing of the strong beat, the weak beat, and the back beat can be recognized by the sound. However, the present invention is not limited to this. The timing of the beat may be visually recognized. Also,
In the above embodiment, the strong beat, the weak beat, and the back beat are not simultaneously generated. However, the present invention is not limited to this. But,
Alternatively, a back beat may be produced simultaneously with a weak beat.

In the above embodiment, even if the back beat is set to be generated, if the tempo is set faster than a predetermined speed, the generation of the back beat is stopped or the tempo is set even if it is generated. Control may be performed so that the sound volume decreases as the speed increases.

[0037]

As described above, according to the present invention, there is provided a metronome which can grasp an accurate timing even when the tempo becomes slow, and can cope with various special patterns of music. can do.
