Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic percussion instrument, and more particularly to an electronic percussion instrument capable of generating a musical sound in response to a strike on a pad as a striking surface.

[0002]

2. Description of the Related Art Generally, there is known an automatic performance device for automatically performing performance based on performance information stored in a recording medium such as a magnetic disk or a magnetic card or performance information stored in a built-in memory. . In such an automatic performance device, by operating an operator such as a start switch and a stop switch provided on the operation panel of the automatic performance device, the start and stop of the automatic performance based on the stored performance information can be performed. It is designed to operate.

Further, a plurality of performance information is usually stored in a recording medium such as a magnetic disk or a magnetic card or a built-in memory. Among the plurality of performance information thus stored, automatic performance is performed. Even when the predetermined performance information to be selected is selected, it is performed by operating the operator provided in the operation panel section of the automatic performance device.

Therefore, in the above-described conventional automatic performance device, in order for the performer to start or stop the automatic performance by the automatic performance device or select performance information, the performer's own hands are required. The operator of the operation panel section had to be operated by using this. Therefore, in order to perform operations such as starting and stopping the automatic performance by the automatic performance device or selecting performance information while the performer is playing another musical instrument, the player must remove the hand from the other musical instrument currently playing. There was a problem that the operator of the operation panel section of the automatic performance device had to be operated after the operation was temporarily suspended.

In order to solve such a problem, in a certain automatic performance apparatus, a foot switch is connected to the outside of the automatic performance apparatus, and the foot switch is operated by a foot so that the stored performance is stored. It was possible to start and stop the automatic performance based on the information.

[0006]

However, even when the foot switch is operated by the foot to start or stop the automatic performance based on the stored performance information,
If you are playing an electronic percussion instrument, such as an electronic drum set that uses both hands and both feet, and is composed by combining a number of electronic drums with pads that are the striking surface for generating musical sounds by striking. However, there is a problem in that it is necessary to take a break from the electronic drum that is currently being played, pause the playing, and then operate the foot switch.

Further, when the performer is performing a rhythm with the electronic drum set while automatically performing the performance based on certain performance information, the other performance information is used in order to perform the automatic performance based on the other performance information. When you select, release the stick you were holding to hit the pad to pause the performance, operate the controls on the operation panel to select other performance information, and then re-hold the stick. There was a problem that I had no choice but to restart the performance.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to temporarily interrupt the performance of the electronic percussion instrument being performed by the performer himself. It is an object of the present invention to provide an electronic percussion instrument capable of controlling automatic performance while the electronic percussion instrument continues to be played without doing so.

[0009]

In order to achieve the above object, an electronic percussion instrument according to the present invention is an electronic percussion instrument which produces a musical tone based on a hit on a pad which is a hitting surface, and stores performance information. Means, read information generating means for generating read information for reading the performance information stored in the storage means on the basis of a hit on the pad, and based on the read information generated by the read information generating means, The performance information reading means for reading the performance information from the storage means and the musical tone generating means for generating a musical tone based on the performance information read by the performance information reading means are provided.

[0010]

The player can generate the read information for reading the performance information by performing the performance operation according to the usual performance method of hitting the pad. Based on the read information, the performance information reading means reads the performance information from the storage means. In this way, it is possible to generate a musical tone by the musical tone generating means on the basis of the read musical performance information and perform an automatic musical performance.

Therefore, it becomes possible to control the automatic performance without interrupting the performance of the usual electronic percussion instrument such as the performance with both hands and both feet.

[0012]

Embodiments of the electronic percussion instrument according to the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of an electronic percussion instrument according to the present invention. In this electronic percussion instrument, a central processing unit (CPU) 1 controls the overall operation of the electronic percussion instrument.
It is configured to control using 0. This CPU
A read-only memory (RO) 10 stores a predetermined program for controlling the overall operation and performance information for performing an automatic performance via a data bus 12.
M) 14, a random access memory (RAM) 16 having a working area in which various registers necessary for executing a program are set, an operator group 18 including various operators to be described later, and an operation It is output by a striking operation of a display unit 20 for displaying a setting state or the like by the child group 18 and a plurality of pads (two pads 22 and 24 are set in this embodiment) connected to the outside. A trigger detection circuit 26 to which a trigger signal is input, a dot position detection circuit 28 to which dot position information output by hitting the pads 22 and 24 is input, and a tone signal for generating a tone signal based on the processing of the CPU 10. Music signal generator 3
0 and 0 are connected.

Further, the tone signal generator 30 is connected to a sound system 32 including a jack for sending a tone signal to the outside.

Therefore, in this electronic percussion instrument, the trigger signal and the hit point position information output by hitting the pads 22 and 24 are input to the trigger detection circuit 26 and the hit point position detection circuit 28, respectively, and the trigger detection circuit 26 is detected. The trigger detection data is output from the
From 8, the hit point position detection data is output. These trigger detection data and dot position detection data are
It is input to the CPU 10 via the bus 12 and processed by the CPU 10.

Similarly, the operator setting information output based on the operation of the operator group 18 is input to the CPU 10 via the data bus 12 and processed by the CPU 10.

The CPU 10 uses these trigger detection data,
Processing the dot position detection data and operator setting information,
The data processed in this way is sent to the musical tone generating section 30 to generate a musical tone signal.

FIG. 2 shows the construction of an operation panel section having an operator group 18 and a display section 20.

The operator group 18 includes a sound source number selection switch 40, a pattern number selection switch 42, a performance mode selection switch 44, a start switch 46,
A stop switch 48, a recording switch 50, a pattern erasing switch 52, a pattern copy switch 54, an instrument sound erasing switch 56, and a ten key 58 for selecting a sound source number, a pattern number, etc. It is configured.

The setting state based on the operation of each operator forming the operator group 18 is read by the CPU 10. The function of each operator will be described below.

The sound source number selection switch 40 is the pad 2
The sound source number of the sound source is selected and set by the trigger signal generated based on the hits of 2, 24. That is, in this embodiment, a plurality of sound sources are set, and it is possible to set for each pad 22, 24 which sound source number the sound source is used to generate a musical sound for hitting each pad. Has been done. Therefore, by setting a musical instrument sound for each sound source, it is possible to generate musical tones having different musical instrument sounds according to the hits on the pads 22 and 24. The setting state of the sound source number selection switch 40 is stored in the RAM 16.

The pattern / number selection switch 42 automatically plays which playing pattern from among a plurality of playing patterns stored as automatic playing information in the ROM 14 in response to a trigger signal generated based on the impact of the pads 22 and 24. It is set whether or not to read as performance information for performing. That is, a plurality of performance patterns are set in the ROM 14 for each pattern number. Then, the pattern numbers of the performance patterns to be read can be assigned to the trigger signals based on the hits of the pads 22 and 24, respectively. Therefore, the performance pattern to be read can be set for each of the pads 22 and 24. This setting status is RA
It is stored in M16.

The performance mode selection switch 44 is used to set in which performance mode the performance pattern selected by the pattern / number selection switch 42 is reproduced, and this setting state is stored in the RAM 16.

As the performance modes, three types of performance modes, "LOOP", "ONE SHOT (one shot)" and "TAP" are set.

"LOOP" is to repeat the performance by returning to the beginning of the performance pattern when the performance pattern has been played to the end. Then, when the pattern number currently being played at "LOOP" and the pattern number designated to perform at "LOOP" match, the performance currently being performed at "LOOP" is stopped. At the same time, the designation for performing the performance with "LOOP" is canceled, and the performance with "LOOP" is terminated.

The "ONE SHOT" is to stop the performance at the time when the performance pattern has been played to the end. That is, the performance pattern is played only once, and the process ends.

"TAP" is to sequentially reproduce a performance pattern "one note" each time a trigger signal is input by striking the pads 22 and 24, and
When the trigger signal is not input for a predetermined time interval or more, the performance pattern is returned to the beginning, and the performance pattern is reproduced one by one from the beginning again. Then, regarding "TAP", "TAP1", "TAP"
2 ”,“ TAP3 ”and“ TAP4 ”and so on 4
The level can be set in stages, and the time interval for returning to the beginning (hereinafter, simply referred to as "reset time") is set longer as the operation proceeds from "TAP1" to "TAP4" in sequence. And this reset time is
It is stored in the ROM 14.

The start switch 46 includes the pad 22,
The operation is performed when the reproduction of the performance pattern is started regardless of the hit of 24.

The stop switch 48 includes the pad 22,
It is operated when the reproduction of the performance pattern is stopped regardless of the hit of 24.

The recording switch 50 stores the performance information, which is generated based on the hitting of the pads 22 and 24, in the RAM 16 when the recording switch 50 is turned on to switch to the recording state. That is, when the pads 22 and 24 are hit, the trigger detection data and the hit point position detection data output from the trigger detection circuit 26 and the hit point position detection circuit 28 are sent to the CPU 10 via the data bus 12 for processing. , And is stored in the RAM 16 as performance information.

Therefore, after a predetermined pattern number is selected by the pattern number selection switch, the recording switch 50 is operated to set the recording state, and when the performer strikes the pads 22 and 24, the performance information based on the strike is obtained. The original performance pattern of the performer is stored as a performance pattern of a predetermined pattern number. Then, when performing playback for confirming the performance pattern thus recorded, the start switch 4
It is sufficient to perform the operation 6 and stop the reproduction by operating the stop switch 48.

The pattern erase switch 52 is
This is operated when deleting the performance pattern stored corresponding to the number. When a pattern number is designated and the pattern erasing switch 52 is operated, the performance pattern stored corresponding to the pattern number is erased.

At this time, the pattern erase switch 5
When 2 is operated, the performance pattern stored in the pattern number designated to be erased is automatically played, and a confirmation message is displayed on the display section 20 asking whether the performance pattern being played may be erased. Therefore, it is possible to confirm whether the performance pattern can be erased. After this confirmation, the pattern erase switch 5
By operating 2, the erasure is executed.

The pattern copy switch 54 changes the performance pattern stored in a predetermined pattern number to
This is to be operated when copying to another pattern number. For example, when it is desired to store a performance pattern that is slightly different from the performance pattern already set to the predetermined pattern number, the pattern copy switch 54 is operated to store the performance pattern at the predetermined pattern number. Copy the playing pattern you are playing to another pattern number. By performing work on the basis of the copied performance pattern, a desired performance pattern can be created more easily and in a shorter time than a new performance pattern is constructed.

At this time, if the pattern copy switch 54 is operated, the pattern
If the performance pattern is already stored in the number,
The performance pattern stored in the pattern number is automatically played, and a confirmation message is displayed on the display section 20 asking whether the performance pattern being played may be changed by copying. It is designed so that you can check whether it is a good performance pattern.
After this confirmation, the pattern copy switch 5
By operating 2, the copy is executed.

The instrument sound erasing switch 56 is operated when the recording switch 50 is in the recording state, whereby the player strikes the pad 22 or the pad 24 to select the trigger signal of the desired pad. Then, until the musical instrument sound erasing switch 56 is operated again, the performance information inputted by the selected trigger signal is deleted from the performance information of the performance pattern being played. Therefore, it is possible to erase only the specific performance information for which an input error has occurred and to re-enter the information.

The display unit 20 has the operator group 1 as described above.
The performer can confirm the setting state of this electronic percussion instrument by displaying the operation state of 8 and a confirmation message.

The operation and operation of the electronic percussion instrument having the above structure will be described with reference to the flow charts shown in FIGS.

This electronic musical instrument reads a trigger signal generated by striking the pads 22 and 24 and striking position information in a well-known main routine (not shown), and C
Processing is performed in PU10.

Similarly, in the main routine, the setting state based on the operation of each operator constituting the operator group 18 is also read and stored, and the start switch 46 and the stop switch 48 are also stored. In addition to the processing based on the operation of the recording switch 50 and the like, the processing for displaying a predetermined display on the display unit 20 is also performed.

In the main routine, CP
When a predetermined time is counted by the U10 timer, FIG.
And the interrupt routine shown in FIG. 4 is executed. That is, although the main routine is normally repeated at high speed, the interrupt routine is started every time a predetermined time elapses, and after execution of the interrupt routine, the main routine is repeated again.

In the interrupt routine, first, in step S302, it is determined whether or not a trigger signal has been input, based on the impact of the pad 22 or the pad 24. The result of this determination is negative (N), that is, pad 2
2 or the pad 24 is not hit and the trigger signal is not input, the process returns to the main routine to end this interrupt routine.

On the other hand, if the determination result of step S302 is affirmative (Y), that is, if the pad 22 or the pad 24 is hit and the trigger signal is input, step S3 is performed.
Go to 04.

In step S304, based on the input trigger signal, the CPU 10 obtains, from the RAM 16, sounding data for sounding the musical instrument sound previously assigned to the trigger signal. Then, this sound generation data is output to the musical sound generating section 30 to perform musical instrument sound generation processing.

In this way, the preset sound of the musical instrument sound is generated with respect to the hit pad 22 or pad 24. That is, in the well-known main routine, when the drum instrument sound is set to the pad 22 and the cymbal instrument sound is set to the pad 24 in the RAM 16 in advance, the pad 22 When is hit, the drum instrument sound set in the pad 22 is sounded, and when the pad 24 is hit, the cymbal instrument sound set in the pad 24 is sounded.

When the process of step S304 is completed, the process proceeds to step S306.

In step S306, the recording switch 50
By the operation of, it is determined whether or not the recording state is set. If this determination result is affirmative, that is, if the recording is in progress, the process proceeds to step S308 to perform the recording process.

In step S308, for the pattern number selected by the pattern number selection switch 42, the musical instrument sound produced in step S304 is stored in the RAM as a performance pattern corresponding to the pattern number.
Store in 16. When the process of step S308 ends, the process returns to the main routine and ends the interrupt routine.

On the other hand, if the result of the determination in step S306 is negative, that is, if the recording is not in progress, the process proceeds to step S310.

In step S310, it is determined whether or not a pattern number is assigned to the RAM 16 corresponding to the input trigger signal. When the result of this judgment is negative, that is, when the pattern number is not assigned to the input trigger signal, the process returns to the main routine and ends the interrupt routine.

On the other hand, if the determination result of step S310 is affirmative, that is, if the input trigger signal is assigned with a pattern number, the process proceeds to step S312. Then, in the processing of step S312 and thereafter, the performance mode is determined, and based on the determined performance mode, the input trigger signal is stored in the RAM 16 in correspondence with the assigned pattern number. The performance pattern is read out and automatically played.

First, in step S312, it is determined whether or not the performance mode is "TAP" based on the operation state of the performance mode selection switch 44. If this determination result is affirmative, that is, if the performance mode is "TAP", the process proceeds to step S314.

In step S314, it is determined whether or not the time elapsed since the same pad was hit last time is longer than or equal to the reset time of "TAP" stored in the ROM 14. If the result of this determination is affirmative, that is, if the time that has elapsed since the pad was hit last time is equal to or longer than the reset time, the process proceeds to step S316.

In step S316, the performance pattern read pointer is returned to the start address of the performance pattern corresponding to the pattern number, and the flow advances to step S318.

Also, if the determination result of step S314 is negative, that is, if the time elapsed since the pad was hit last time is shorter than the reset time, step S318.
Go to.

In step S318, the event of the performance pattern at the address where the read pointer is located is read out and sent to the tone signal generation section 30 to perform sound generation processing.
At the same time, the address of the read pointer is advanced. When the process of step S318 is completed, the process returns to the main routine and the interrupt routine is completed.

Therefore, in the processing in the case where the performance mode is "TAP" in steps S314 to S316 described above, if the trigger signal is not input by the pad hit for more than the reset time, the program always returns to the beginning of the performance pattern, The performance pattern will be pronounced.

When a trigger signal for hitting the pad is input within the reset time, the performance pattern is sequentially sounded one event at a time according to the trigger signal for hitting the pad.

On the other hand, when the result of the determination in step S312 is negative, that is, when the performance mode is not "TAP", the process proceeds to step S320.

At step S320, the performance mode is "O".
It is determined whether or not it is "NE SHOT". This judgment result is affirmative, that is, the performance mode is "ONE SHO.
If “T”, the process proceeds to step S322.

In step S322, step S310.
The "pattern start" process for starting the automatic performance is performed according to the performance pattern corresponding to the pattern number obtained in (1), and the automatic performance according to the performance pattern is started. When the process of step S322 is completed, the process returns to the main routine and the interrupt routine is completed.

In this case, the performance mode is "ON."
Since it is "E SHOT", if the performance pattern is automatically played only once, the performance is stopped.

On the other hand, if the result of the determination in step S320 is negative, that is, if the performance mode is not "ONE SHOT", the process proceeds to step S324. In this case, even if the performance mode is "TAP", "ONE SHO"
Since it is not "T", the performance mode is set to "LOOP".

In step S324, it is determined whether or not the automatic performance is currently performed by any of the performance patterns. If the result of this determination is negative, that is, if the automatic performance is not currently being performed according to the performance pattern, then the processing advances to step S322, and the automatic performance is started according to the performance pattern corresponding to the pattern number obtained in step S310. Pattern start ”processing is performed to start sounding according to the performance pattern. When this process ends, the process returns to the main routine to end this interrupt routine.

In this case, the performance mode is "LO
Since it is “OP”, unless the “pattern stop” processing in step S328 described later is performed, the automatic performance based on the performance pattern is repeated.

On the other hand, if the determination result in step S324 is negative, that is, if the automatic performance is currently being performed according to the performance pattern, the process proceeds to step S326.

In step S326, it is determined whether or not the pattern number of the performance pattern being automatically played matches the pattern number obtained in step S310. If this determination result is affirmative, that is, if the pattern number of the performance pattern being automatically played matches the pattern number obtained in step S310, the process proceeds to step S328.

In step S328, "pattern stop" for stopping the automatic performance of the performance pattern during the automatic performance.
Processing is performed and the production of musical tones of the playing pattern is stopped in the main routine. When this process ends, the process returns to the main routine to end this interrupt routine.

On the other hand, if the determination result in step S326 is negative, that is, if the pattern number of the performance pattern being played is different from the pattern number obtained in step S310, the process proceeds to step S322. In step S322, "pattern start" processing for starting an automatic performance is performed according to the performance pattern corresponding to the pattern number obtained in step S310.
Starts automatic performance according to the performance pattern. When this process ends, the process returns to the main routine to end this interrupt routine.

In this case, the performance mode is "LO
Since it is “OP”, unless the “pattern stop” processing in step S328 described later is performed, the automatic performance based on the performance pattern is repeated.

Further, in this case, the performance pattern which was being automatically played may be kept playing or may be stopped.

As described above, the performance pattern selected by the trigger signal based on the striking of the pad is automatically played in the selected performance mode.
Therefore, it is possible to perform an automatic performance based on a preset performance pattern without changing the performance method of a normal electronic percussion instrument such as hitting a pad.

Next, a second embodiment of the present invention will be described with reference to FIGS. 1 to 4 similarly to the first embodiment. In the second embodiment, the pattern number is assigned to each pad in the first embodiment, but the pattern number is assigned to each pad in consideration of the hitting position. is there.

That is, as in the first embodiment, the trigger signal based on the striking of the pad is not detected by the trigger detection circuit 28, and the pattern number is not assigned to the trigger signal. The trigger signal and the dot position information based on the detected trigger signal are detected, and the pattern number can be selectively changed by the trigger detection data and the dot position detection data output from the trigger detection circuit 28 and the dot position detection circuit 38. It is a thing.

That is, the hit point position detection circuit 28 determines whether the central portion of the pads 22, 24 has been hit or the outer peripheral portion has been hit. Then, the dot-spot position detection circuit 28 outputs “dot-spot position detection data: 0” when the central portions of the pads 22 and 24 are hit, and the pads 22 and 2 are output.
When the outer peripheral part of 4 is hit, "dotting position detection data:
1 ”is to be output.

On the other hand, the trigger detection circuit 26 uses the pad 22
When is hit, "trigger detection data: 0" is output, and when the pad 24 is hit, "trigger detection data: 1" is output.

Then, different patterns and numbers are respectively assigned to the pads 22 and 24 in the central portion and the outer peripheral portion for each pad in advance.

The CPU 10 a. When "trigger detection data: 0" and "dotting position detection data: 0", the central portion of the pad 22 was hit. B. When "trigger detection data: 0" and "dotting position detection data: 1", the outer peripheral portion of the pad 22 was hit. C. When "trigger detection data: 1" and "dotting position detection data: 0", the central portion of the pad 24 is hit d. When "trigger detection data: 1" and "dotting position detection data: 1", it is determined that the outer peripheral portion of the pad 24 has been hit, and the hitting position is registered in the pattern number and stored in the pattern number. It performs processing such as reproduction or stop of the performance pattern.

By the way, the player operates the operator group 18 to assign "pattern number: 1" to the central portion of the pad 22 and "pattern number: 2" to the outer peripheral portion of the pad 22, It is assumed that "pattern number: 3" is assigned to the central portion of the pad 24, "pattern number: 4" is assigned to the outer peripheral portion of the pad 24, and "performance mode: LOOP" is assigned to the "pattern number: 1". “Pattern number: 2”
"Performance mode: TAP1" is assigned to, and "Pattern number: 3" is assigned to "Performance mode: ONE SHOT"
, And “playing mode: TAP2” is assigned to “pattern number: 4” and stored in the RAM 16.

With the above arrangement, the CPU 10 performs the same processing as the interrupt routine described above.

For example, when the player hits the central portion of the pad 22, the CPU 10 reads the data for causing the musical instrument sound registered in the central portion of the pad 22 from the ROM 14 and sends it to the tone signal generating means 30 ( Step S30
At the same time as 4), the automatic performance of the performance pattern assigned to "pattern number: 1" is started (step S322).

At this time, there is already a performance pattern that is being automatically played, and the pattern number that is being automatically played is registered in the central portion of the pad 22 "Pattern number:
When it is equal to "1", the automatic performance of the performance pattern is stopped (step S326, step S32).
8).

On the other hand, although there is a performance pattern that is already being automatically played, the pattern number that is being automatically played is registered in the center portion of the pad 22 "pattern number:
1 ”and the performance mode of the performance pattern being automatically performed is“ LOOP ”or“ ONE SHOT ”, the automatic performance of the performance pattern being automatically performed is stopped, and then the“ pattern number ”is selected. The automatic performance according to the performance pattern assigned to "1" is started (step S322). Therefore, the performer does not need to perform the operation for stopping the performance pattern that is already being automatically played, and the operation is simplified.

Although there is already a performance pattern being automatically played, if the performance mode of the performance pattern being automatically played is "TAP1" to "TAP4", the performance pattern being automatically played is The automatic performance of the performance pattern assigned to "pattern number: 1" is started without performing any processing relating to the automatic performance (step S322). Therefore, the performer automatically performs the performance pattern of "pattern number: 1" in the performance mode of "LOOP", while performing "TAP1" to "T".
It is possible to perform an automatic performance in parallel with the performance pattern of the performance mode of "AP4".

When the performance pattern of "pattern number: 1" is played to the end, the performance mode becomes "LO".
Since it is set to "OP", "Pattern number:
Return to the beginning of the performance pattern of "1" and repeat the performance of the performance pattern of "pattern number: 1".

Next, when the performer strikes the central portion of the pad 24, the CPU 10 reads the data for causing the musical instrument sound registered in the central portion of the pad 24 from the ROM 14 and sends it to the musical tone signal generating means 30. (Step S304)
At the same time, the performance of the performance pattern assigned to "pattern number: 3" is started (step S32).
2).

At this time, there is already a performance pattern that is being automatically played, but the pattern number that is being automatically played is different from the "pattern number: 1" registered in the central portion of the pad 24, and it is automatic. The performance mode of the performance pattern being played is "LOOP" or "ONE SHO".
In the case of "T", the automatic performance of the performance pattern during the automatic performance is stopped, and then the automatic performance of the performance pattern assigned to "pattern number: 3" is started (step S322). Therefore, the performer does not need to perform the operation for stopping the performance pattern that is already being automatically played, and the operation is simplified.

Although there is already a performance pattern that is being automatically played, if the performance mode of the performance pattern that is being automatically played is "TAP1" to "TAP4", the performance pattern of that performance is automatically changed. The automatic performance of the performance pattern assigned to "pattern number: 3" is started without performing any processing relating to the performance (step S322). For this reason, the performer is "ONE SHO
It is possible to perform the automatic performance of the performance pattern of "TAP1" to "TAP4" in parallel while the automatic performance of the performance pattern of "pattern number: 3" is performed in the performance mode of "T".

When the performance pattern of "pattern number: 3" is played to the end, the performance mode is set to "ON".
Since it is set to "E SHOT", the performance of the performance pattern is stopped.

When the performer strikes the outer peripheral portion of the pad 22, the CPU 10 reads the data for causing the musical instrument sound registered on the outer peripheral portion of the pad 22 from the ROM 14 and sends it to the tone signal generating means 30 ( (Step S304)
At the same time, the automatic performance of the performance pattern assigned to "Pattern number: 2" is started. At this time, the "Pattern number: 2" is displayed as "TAP
Since the performance mode “1” is assigned, the performance information of the performance pattern assigned to “pattern number: 2” is set to 1 each time the performer hits the outer peripheral portion of the pad 22.
Each event is read out and sounded (step S318).

When the time interval for hitting the outer peripheral portion of the pad 22 becomes longer than the time registered as the reset time of "TAP1", "pattern number: 2"
The address of the read pointer for reading the performance pattern of No. 2 is returned to the start address of the performance information of the performance pattern of "Pattern number: 2" (step S31).
4, step S316).

Further, when the performer hits the outer peripheral portion of the pad 24, the CPU 10 reads out from the ROM 14 the data for causing the musical instrument sound registered in the outer peripheral portion of the pad 24 to be sent to the musical tone signal generating means 30 ( Step S30
At the same time as 4), the performance of the performance pattern assigned to "Pattern number: 4" is started. At this time, since the performance mode of “TAP2” is assigned to “pattern number: 4”, each time the performer hits the outer peripheral portion of the pad 24, “pattern number: 4”.
The performance information of the performance pattern assigned to is read out and sounded (step S318).

When the time interval for hitting the outer peripheral portion of the pad 24 becomes longer than the time registered as the reset time of "TAP2", "pattern number: 4"
The address of the read pointer for reading the performance pattern of No. 4 is returned to the start address of the performance information of the performance pattern of "Pattern number: 4" (step S31).
4, step S316).

A pad in which "TAP" is registered as the performance mode (in the present embodiment, the pad 22
(Playing mode: TAP1) and pad 24 (playing mode: TAP2). ), The playing pattern that is already playing is not stopped. Therefore, the performer hits the central portion of the pad 22 and sets the performance pattern of "pattern number: 1" in the "performance mode: L".
While playing with "OOP", at the same time, pad 22
The performance pattern of "pattern number: 2" can be played in "performance mode: TAP1" by striking the outer peripheral portion of.

Further, the performance mode of the performance pattern is "TA
P ”, and if the performance information of the performance pattern includes performance control information for instructing the sound quality of the musical instrument sound to be generated, in addition to the pronunciation information indicating the type of the musical instrument sound to be generated, 1 Each time the pad is struck, the pronunciation information is generated based on the performance control information stored to be pronounced at a time before the pronunciation information is generated.

An example of such performance control information is M
There is control change information in IDI.

Next, a third embodiment according to the present invention will be described with reference to FIGS. 1 to 4 similarly to the second embodiment. In the third embodiment, it is possible to change the sound of a musical instrument sounded by hitting a pad or the sound of a musical instrument or sound quality of a performance pattern to be played, based on the hit point position detection data.

That is, in the third embodiment, it is possible for the hit point position detection circuit 28 to determine how far away from the center of the pads 22 and 24 the position has been hit. Yes, the dot position detection circuit 28
Is to send the hit point position detection data obtained from the "distance from the center of the pad to the hit position".

Incidentally, such hitting point position detection data is not obtained by the above method, but by using a sensor, the output of the sensor corresponding to the distance between the hit position and the center or the outer peripheral portion of the pad is You may make it obtain | require by / D conversion.

Two types of musical instrument sounds are assigned to the pads 22 and 24, respectively, and the volume balance of the two types of musical instrument sounds can be changed according to the value of the hit point position detection data. . This volume balance may be obtained by calculation, or may be obtained by referring to a table stored in advance in the ROM 14.

Therefore, for example, the sound of hitting the central portion of the cymbal and the sound of hitting the outer peripheral portion of the cymbal are stored in the pad, and the volume balance between the two types of musical instrument sounds is adjusted according to the position where the pad is hit. By making it variable, it is possible to express a natural timbre change that is extremely close to when the cymbal is actually hit.

That is, when the center of the pad is hit, the volume of the sound of the center of the cymbal is increased and the volume of the sound of the outer periphery of the cymbal is decreased. On the other hand, when you strike near the outer periphery of the pad, the volume of the sound that strikes the center of the cymbal is reduced, and
Increases the volume of the sound that strikes the outer periphery of the cymbal. In this way, the same tone change as when the cymbal is actually hit can be expressed.

When the performance pattern of the pattern number stored in the pad is played, the CPU 10 causes the ROM to
The performance control information (for example, pitch information, sound quality information, and tone length information) indicating the property of the musical tone to be generated is added to the pronunciation control data read out from the No. 14 and transmitted to the musical tone signal generating unit 30. By reflecting it in correspondence with the value of the detected data, it becomes possible to variably control the tone quality of the musical sound that is produced when the performance pattern is played, as described above, and realize an extremely natural change in tone color. You will be able to control the pitch.

Although not particularly described in detail in the above embodiment, the player may actually hit the pad with a stick or the like, or MIDI or the like, for hitting the pad which is the hitting surface of the electronic drum. Hit information indicating that the pad of the electronic drum has been hit may be given via the communication means according to.

That is, in the above embodiment, the stored automatic performance information is controlled by the trigger signal and the hitting position information inputted from the outside, but the automatic performance information is controlled by the MIDI note information inputted from the outside. May be controlled.

[0106]

Since the present invention is constructed as described above, it has the following effects.

An electronic percussion instrument which produces a musical tone based on a hit on a pad, which is a hitting surface, and storage means for storing performance information, and the performance information stored in the storage means for hitting the pad. Read information generating means for generating read information for reading, performance information reading means for reading the performance information from the storage means based on the read information generated by the read information generating means, and the performance information reading means Since the musical tone generating means for generating a musical tone is provided based on the read musical performance information, the performer reads the musical performance information by a musical performance operation by a normal musical performance method of hitting a pad. Can be generated.

Then, based on the read information, the performance information reading means reads the performance information from the storage means. In this way, a musical tone is generated by the musical tone generating means on the basis of the read musical performance information so that the automatic musical performance can be performed.

Therefore, it becomes possible to control the automatic performance without interrupting the performance of the usual electronic percussion instrument such as the performance with both hands and feet. There is no need to interrupt the performance being performed by the person himself.
