The metronome sound is started and stopped at the tempo according to the tempo value.

FIG. 4 is an internal block diagram of the electronic drum pad of this embodiment.

FIG. 4 shows a CPU 23 connected to the bus 50 for controlling the entire electronic drum pad 1, a ROM 24 in which a rhythm pattern for practice and the like are stored, and a RAM 25 used as a work area. There is. still,
The ROM 24 also stores musical tone data of acoustic drums and the like. Further, in FIG.
Based on the signal detected by the mesh head sensor 14, a tone generation device 26 for generating a tone signal from predetermined tone data read from the ROM 24, and a tone signal from the tone generation device 26 is emitted as a tone according to an instruction from Speaker 40 is also shown. It should be noted that this tone generation device 26
Then, as described above, the tone signal which is the basis of the metronome sound is also generated.

Further, in FIG. 4, LEDL12, LEDR
13, the mesh head sensor 14, and the I / O controller 27 that sends and receives signals to and from them are also shown.

The mesh head sensor 14 outputs a signal corresponding to the impact received by the mesh head 11 shown in FIG. 2 and sends it to the CPU 23 via the I / O controller 27.

The operation of the electronic drum pad 1 of this embodiment will be described below with reference to FIGS. 2 to 4.

The electronic drum pad 1 has a normal mode in which a musical tone corresponding to the hitting position is produced when the mesh head 11 which is the hitting surface is hit, and a tempo setting mode for setting a desired tempo. It has two modes.

First, in the normal mode, the mesh head sensor 14 is hit by hitting the mesh head 11.
Outputs a signal corresponding to this hit, and this output signal is sent to the CPU 23, and the musical tone corresponding to this hit is determined. As a result, the musical tone generator 26 is instructed to read the musical tone data of this musical tone. Upon receiving the instruction, the musical sound generating device 26 reads out predetermined musical sound data from the ROM 24 to generate a musical sound signal, and transmits this musical sound signal to the speaker 40. Thus, in the normal mode, the musical sound corresponding to the hit on the mesh head 11 is output to the speaker 4
Sound is emitted from 0.

Switching from the normal mode to the tempo setting mode is performed by pressing the tap switch 22c shown in FIG.

There are two methods for setting the tempo in the tempo setting mode: a method of hitting the mesh head 11 at an interval according to a desired tempo and a method of pressing the tap switch 22c at an interval according to a desired tempo. There is a way.

In the method of striking the mesh head 11 at an interval according to a desired tempo, the striking interval with respect to the mesh head 11 is measured, and in the method of pressing the tap switch 22c at an interval according to a desired tempo, the tap switch 22c is pressed. The interval of pressing with respect to 22c is measured.

The mode switching from the tempo setting mode to the normal mode after setting the tempo by any of the above methods differs as follows according to the tempo setting method adopted in the tempo setting mode. Done in a way.

When the tempo is set by hitting the mesh head 11, the mode is switched by pressing the tap switch 22c normally.
When the tempo is set by pressing the tap switch 22c, the mode is switched by continuing to press the tap switch 22c for a predetermined time or longer.

Here, a usage mode of the electronic drum pad 1 in which a desired tempo is set will be described.

Assuming that the tempo setting in the tempo setting mode has the tempo value 120, the tempo value "120" is displayed on the display 21 as shown in FIG.

Next, the song switch 22d shown in FIG. 3 is pressed to select a rhythm pattern for practice. The pattern name is displayed on the display 21 shown in FIG. 3 in sequence every time the song switch 22d is pressed.

A desired pattern name is displayed, and start /
When the stop switch 22e is pressed, the rhythm pattern corresponding to the pattern name displayed on the display 21 is changed to
LEDL12 and LEDR13 under the set tempo
It is expressed by lighting.

FIG. 5 is a diagram showing LEDs L and LEDR which are turned on in accordance with the selected rhythm pattern.

FIG. 5 shows an LED located on the left side of the performer.
The lighting timings of L12 and the LED R13 located on the right side of the performer are shown.

In this electronic drum pad 1, the LEDs L12 and LEDR13 are turned on at the set tempo, and the metronome sound is emitted at the set tempo, and LE
By hitting the mesh head 11 following the lighting of the DL 12 and the LED R 13, the rhythm pattern can be learned at a desired tempo. The currently set tempo can be changed by operating the increment switch 22a and the decrement switch 22b shown in FIG.

Now, the operation of the electronic drum pad 1 will be described in more detail with reference to the flowchart of the routine executed by the CPU 23.

FIG. 6 is a flow chart of the main routine executed in the electronic drum pad of this embodiment.

When a power switch (not shown) of the electronic drum pad 1 is turned on, a subroutine "initialization processing" for initializing the system is executed in step S1 of the main routine shown in FIG. Since this subroutine'initialization process' is not related to the present invention, illustration and description of the flowchart are omitted.
Then, the process proceeds to step S2, and the subroutine "pad process" is executed.

FIG. 7 is a flowchart of the subroutine "pad processing".

Step S11 of the subroutine shown in FIG.
Then, it is determined whether or not the mesh head 11 has been hit. This is determined by whether or not a signal is sent from the mesh head sensor 14.

If it is determined in step S11 that the mesh head 11 has not been hit, the subroutine "pad process" is exited and the process returns to the main routine.

When it is determined in step S11 that the mesh head 11 has been hit, the process proceeds to step S12, and it is determined whether or not the current mode is the tempo setting mode of the normal mode and the tempo setting mode. .

Here, the RAM of this electronic drum pad 1
The register area provided in 25 will be described.
Table 1 shows the details.

[0047]

[Table 1]

As shown in Table 1, the register area provided in the RAM 25 has a "CurMode" register, a "TapSwOn" register, and a "PadO" register.
The value stored in the n'register is recorded.

When the mode of the electronic drum pad 1 is the normal mode, "0" is stored in the "CurMode" register, and when the mode is the tempo setting mode, "1" is stored in the "CurMode" register. It When the initialization process is performed on the system, "0" is stored in this register.

When the first press on the tap switch 22c is detected after switching from the normal mode to the tempo setting mode, "1" is stored in the "TapSwOn" register. However, during the system initialization process and when switching from the normal mode to the tempo setting mode, the'Tap
“0” is stored in the SwOn ′ register.

When the first hit on the mesh head 11 is detected after switching from the normal mode to the tempo setting mode, "1" is stored in the "PadOn" register. However, at the time of system initialization processing and when switching from normal mode to tempo setting mode, 'PadOn'
“0” is stored in the register.

Here, in step S12 of FIG.
When it is determined that the current mode is not the tempo setting mode, that is, when the value stored in the above-mentioned'CurMode 'register is “0”, the description is returned to the description. In this case, it is determined that the impact is just in the normal mode, and the process proceeds to step S15, and the subroutine "sounding instruction process" is executed. In this "pronunciation instruction processing" subroutine, a "striking" flag (not shown) is set which means that the mesh head 11 has been struck in the normal mode. This'hit 'flag is also RAM
25. After that, the process exits this subroutine "pad processing" and returns to step S3 of the main routine.

When it is determined in step S12 that the current mode is the tempo setting mode, step S1
3, the determination as to whether or not the tap switch 22c has been pressed is made based on the value stored in the above-mentioned'TapSwOn 'register.

"1" is set in this "TapSwOn" register.
Is stored, it means that the mesh head 11 is hit while the tempo is set by pressing the tap switch 22c, and the process proceeds to step S15. The processing in step S15 has been described above, and will be omitted.

On the other hand, if "0" is stored in this "TapSwOn" register, it means that the tap switch 22c, which means the end of the tempo setting due to the impact on the mesh head 11, has not been pressed yet,
It proceeds to step S14.

In step S14, the mesh head 11
The striking interval for is measured. If the current hit is the first hit in the tempo setting mode, a counter that counts up at a predetermined time interval is started. From the next hit, the count value at that time is sequentially stored in the memory (this causes the time interval for each hit to be stored in the memory, and when the tempo setting mode ends (step S454, which will be described later), these memories are stored. Set the tempo from the stored value). After this process, the process returns to step S3 of the main routine. In the main routine, a subroutine "sound generation process" is executed in step S3.

In this subroutine "sounding process", it is judged whether or not the above-mentioned "hit" flag provided in the RAM 25 is set. If the "hit" flag is set, it is detected by the mesh head sensor 14. A process for producing a musical tone corresponding to the signal is performed, and if the "hit" flag is not set, the process proceeds to step S4. It should be noted that the illustration and detailed description of the subroutine'sound generation processing 'are omitted because they are known techniques.

FIG. 8 is a flowchart of the subroutine "manipulator process".

Step S41 of the subroutine shown in FIG.
Then, it is determined whether or not there is a change in the switch group included in the electronic drum pad 1. Step S4
When it is determined in 1 that there is no change in any of the switches in the switch group, the subroutine'manipulator process' is exited and the process proceeds to step S5 of the main routine. In addition, in the electronic drum pad 1 of the present embodiment, the tap switch 22c is not pressed.
It is recognized that it is composed of an "ON" operation for 2c and an "OFF" operation for the tap switch 22c. Therefore, the state change referred to in step S41 includes the change from the “OFF” state to the “ON” state, and the “O” state.
Both changes from the N'state to the'OFF 'state are included.

When it is determined in step S41 that the state of any of the switches in the switch group has changed, the process proceeds to step S42, and it is determined whether or not the changed switch is the tap switch 22c. .

When it is determined in step S42 that the changed switch is not the tap switch 22c, the process proceeds to step S46, and it is determined whether the changed switch is a switch other than the tap switch 22c. .

When it is determined in step S46 that the changed switch is not the switch other than the tap switch 22c, the subroutine "manipulator process" is exited and the process proceeds to step S5 of the main routine.

When it is determined in step S46 that the changed switch is a switch other than the tap switch 22c, the process proceeds to step S47, and it is determined whether or not the change is an ON operation for the switch.

When it is determined in step S47 that the change is an "ON" operation for the switch, the process proceeds to step S49, and the subroutine "other switch O" is selected.
N processing 'is executed and the change is'O
If it is determined that it is not the N'operation, the process proceeds to step S48, and the subroutine "other switch OFF processing" is executed. In addition, these subroutines'other switch O
The description of the “N process” and the “other switch OFF process” is irrelevant to the present invention and will not be repeated.

These subroutines'other switches O
After the "N process" and the "other switch OFF process" are executed, the subroutine "manipulator process" is exited and the process proceeds to step S5 of the main routine.

On the other hand, when it is determined in step S42 that the changed switch is the tap switch 22c, the process proceeds to step S43, and it is determined whether or not the change is an "ON" operation for the switch.

In step S43, the change is an "ON" operation for the switch (from the "OFF" state to the "O" state.
Change to N ′ state), step S
Go to 45, subroutine "Tap switch ON processing"
Is executed.

FIG. 9 shows the subroutine'tap switch O '
It is a flow chart of N processing '.

Step S45 of the subroutine shown in FIG.
In 1, it is determined whether or not the current mode is the tempo setting mode. This is determined by the value stored in the above-mentioned'CurMode 'register.

In step S451, 'CurMo
The value stored in the de 'register is "0",
If it is determined that the current mode is not the tempo setting mode, the process proceeds to step S452, and the current mode is switched to the tap setting mode. This gives you the'CurMode '
The value "1" is stored in the register, and "TapSwO"
The value "0" is stored in the n'register 'and the'PadOn' register. After that, the process exits the subroutine "tap switch ON process", proceeds to step S46 of the subroutine "manipulator process" shown in FIG. 8, and then returns to step S5 of the main routine.

In step S451, 'CurMo
The value stored in the de 'register is "1",
When it is determined that the current mode is the tempo setting mode, the process proceeds to step S453 and it is determined whether or not the mesh head 11 has not been hit. this is,
It is determined by the value stored in the'PadOn 'register.

When it is determined in step S453 that the mesh head 11 has already been hit, that is, the value stored in the'PadOn 'register is "1".
If so, the process proceeds to step S454, and it is determined that the tempo setting by hitting the mesh head 11 is completed, and the mode is switched from the tempo setting mode to the normal mode. At this time, the value “0” is stored in the “CurMode” register. Then, after exiting this subroutine'tap switch ON processing 'and proceeding to step S46 of the subroutine'manipulator processing' shown in FIG. 8,
The procedure returns to step S5 of the main routine.

When it is determined in step S453 that the mesh head 11 has not been hit, that is, when the value stored in the'PadOn 'register is "0", the process proceeds to step S455 and the tap switch 22c is operated. A'tempo measurement process' for measuring the interval of pressing is executed. In this tempo measurement process, when the switch is turned on for the first time after the tempo setting mode is set, a counter that counts up at a predetermined time interval is started. If it is turned on thereafter, the count value at that time is sequentially stored in the memory (when this on operation reaches a predetermined time, (S64, 65)).
Exit the tempo setting mode and set the tempo based on the time interval stored in these memories). Then, the process proceeds to step S456, and in order to measure the pressing time of the tap switch 22c, the timer switch ON interval counter is cleared to zero and started. The start of this timer switch ON interval counter is
This counter is a measure for counting up by a "timer switch ON interval counter process" which is a timer interrupt routine described later in detail. The value stored in the register for the tap switch ON interval counter is also recorded in the register area provided in the RAM 25. Thereafter, the subroutine "tap switch ON process" is exited, the process proceeds to step S46 of the subroutine "manipulator process" shown in FIG. 8, and then the process returns to step S5 of the main routine.

Here, in step S43 of the subroutine "operator processing" shown in FIG. 8, the change is "OFF" rather than "ON" operation for the tap switch 22c.
When it is determined that the operation is performed (change from the'ON 'state to the'OFF' state), the explanation will be given by returning to the story.

At this time, the process proceeds to step S44, and the subroutine "tap switch OFF process" is executed.

FIG. 10 is a flowchart of the subroutine "tap switch OFF processing".

Step S4 of the subroutine shown in FIG.
At 41, it is determined whether or not the current mode is the tempo setting mode. This is determined by the value stored in the'CurMode 'register.

If it is determined in step S441 that the current mode is not the tempo setting mode, this subroutine "tap switch OFF processing" is exited and the process shown in FIG.
After proceeding to step S46 of the subroutine "manipulator process" shown in, the procedure returns to step S5 of the main routine.

If it is determined in step S441 that the current mode is the tempo setting mode, step S441
Proceeding to 442, it is determined whether or not the tap switch ON interval counter has been started in step S456 of the subroutine "tap switch ON processing" shown in FIG.

If it is determined in step S442 that the start has not been made, that is, if the tempo setting mode has been set but the tempo setting has not started by pressing the tap switch 22c, this subroutine "tap switch OFF process" is executed. After exiting the process, the process proceeds to step S46 of the subroutine "manipulator process" shown in FIG. 8, and then returns to step S5 of the main routine.

If it is determined in step S442 that this counter has been started, step S44
As will be described later in detail, the tap switch ON interval counter is stopped to indicate that the tap switch ON interval counter is not counted up. After that, the process exits the subroutine "tap switch OFF process", proceeds to step S46 of the subroutine "manipulator process" shown in FIG. 8, and then returns to step S5 of the main routine.

Step S5 of the main routine shown in FIG.
Then, a subroutine "display processing" (not shown) for performing display processing on the display 21 shown in FIGS. 3 and 4 is executed. Then, it returns to step S2. It should be noted that the description of this sub-routine'display processing 'is omitted because it is irrelevant to the present invention.

Next, in this electronic drum pad 1,
A routine'tap switch ON interval counter processing 'which is executed by a timer interrupt separately from the main routine shown in FIG. 6 will be described.

FIG. 11 shows the routine'tap switch ON.
It is a flowchart of an interval counter process'.

This routine shown in FIG. 11 is a timer interrupt routine for detecting the pressing time with respect to the tap switch 22c, that is, the above-mentioned'ON 'operation time with respect to the tap switch 22c. Tap switch ON Interval counter is incremented.

In step S61 of this routine, it is determined whether or not the tap switch ON interval counter has been started. If it is determined in step S61 that the counter has not been started, this routine ends.

When it is determined in step S61 that the counter has been started, the process proceeds to step S62 and the counter value is incremented. afterwards,
It proceeds to step S63.

In step S63, it is determined whether or not the counter value is the same as the tap tempo mode Exit interval. This determines whether or not the “ON” operation time of the tap switch 22c represented by the counter value has reached a predetermined time (tap tempo mode Exit interval) indicating the end of tempo setting by the tap switch.

In step S63, if the counter value has not reached the tap tempo mode Exit interval, this routine ends.

When the counter value becomes equal to the tap tempo mode Exit interval in step S63, the process proceeds to step S64, the tap switch ON interval counter is stopped, and the process proceeds to step S65.

In step S65, the tap switch 22
When the tempo setting is completed by pressing c, the tempo mode is switched to the normal mode. Then, this routine ends.

As described above, when the batting is detected in the normal mode, a musical tone is generated, and when the tap switch is turned on, the tempo setting mode is set. In this tempo setting mode, when a batting is detected, the batting time interval is detected, and when the tap switch is turned on again, the mode returns to the normal mode, and at the same time, the tempo is set based on the set time interval. It Here, the set time interval may correspond to a quarter note or an eighth note.

After setting the tempo setting mode,
If the tap switch is turned on again before the hit is detected, the time interval when the tap switch is turned on is detected. In this case, when the tap switch is turned on for a predetermined time or longer, the tempo setting mode is returned to the normal mode, and the tempo is set based on the time interval when the tap switch is turned on.

In the electronic drum pad of the present embodiment described above, a desired musical sound can be generated by striking the striking surface, and the tempo of the metronome is set at the tap switch and the striking interval of the striking surface. It is possible and easy to operate.
