[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic percussion instrument that electronically generates percussion sounds.

0002

[Prior Art] An electronic percussion instrument is known which is equipped with multiple keypads corresponding to drums, cymbals, tom-toms, etc., and allows drum sounds, cymbal sounds, tom-tom sounds, etc. from a built-in PCM sound source to be obtained by operating each keypad. It is being Also known is an electronic keyboard that generates automatic accompaniment sounds for a rhythm section in response to the selected rhythm type.

0003

[Problem to be Solved by the Invention] Such electronic percussion instruments generate a single note corresponding to a single strike of a drum, cymbal, tom-tom, etc., and a desired rhythmic sound is generated by a series of keypad operations. was. Therefore, a certain amount of knowledge and skill is required to produce complex percussion patterns or percussion phrases. On the other hand, electronic keyboards that generate rhythm accompaniment sounds generate fixed patterns of rhythm accompaniment sounds corresponding to the type of rhythm, and do not generate rhythm sounds by playing the keyboard itself. An object of the present invention is to provide an electronic percussion instrument that can easily generate complex percussion patterns or percussion phrases without requiring advanced skills.

0004

[Means for Solving the Problems] The electronic percussion instrument of the present invention includes:
a storage means that stores percussion pattern data for a plurality of phrases, each phrase consisting of a plurality of percussion instrument tone sequences, in association with a plurality of keypads, and percussion pattern data of corresponding phrases in response to operations of the keypads; and a musical tone control circuit that calls and outputs the sound data to the sound source circuit, and outputs the hit data of a single hit sound to the sound source circuit in response to the operation of another keypad.

[0005]

[Operation] Complex percussion patterns or percussion phrases can be easily produced without requiring advanced skills. Furthermore, by a series of keypad operations, different percussion patterns or continuous combinations of percussion phrases can be produced, allowing improvisational percussion performances.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view showing the main parts of an electronic percussion instrument according to an embodiment of the present invention. This electronic percussion instrument is a shoulder-type electronic instrument like a guitar, and the neck part
It consists of a body 2 and a shoulder strap 3. The neck portion 1 is provided with a plurality of keypads 1a corresponding to left-handed operation, and the body 2 is provided with a plurality of keypads 2a corresponding to right-handed operation. PCM sound sources such as drums and cymbals are built into the body 2, and sound signals based on these sound sources are generated by operating the keypads 1a and 2a. The sound signal is supplied to an amplifier 5 via a cord 4, and is produced by a speaker 6.

[0007] Adjacent to the keypad 1a of the neck portion 1, a performance mode changeover switch 8 for single-strike/phrase-strike sounds is provided. In single-press sound mode, keypad 1a,
In response to the operation of 2a, single hit sounds of various cymbals (open hi-hat, closed hi-hat, etc.) and various drums are generated. The keypad 1a on the neck 1 is used to keep rhythms such as hi-hat cymbals and bass drums, and the keypad 2a on the body 2 is used to generate rhythms, accents, and melodies for tom-toms, snare drums, cymbals, etc. .

In the phrase beat mode (one shot beat mode), 1
A single pattern phrase of one measure to two measures is sounded. This phrase sound is a series of drum sounds made by one type or a combination of two or more types of cymbals and drums, and a different phrase is assigned to each keypad. Complete phrase pronunciation can be obtained with a single key operation, and improvised percussion performance effects can be obtained by combining different keypad operations.

FIG. 2 is a block diagram of the main parts of the musical tone generation circuit built into the body 1. The musical tone control circuit 11 is a CP
It detects the operation of the keypads 1a and 2a and the mode changeover switch 8 and outputs the corresponding performance data to the sound source circuit 12. In the single-strike sound mode, a key number corresponding to the type of musical instrument and velocity data corresponding to the strength of the keystroke are given to the sound source circuit 12. The sound source circuit 12 reads out the PCM signal corresponding to the key number from the waveform ROM 13,
The amplitude is modulated using velocity data and the D/A converter 1
4.

In the phrase striking mode, the musical tone control circuit 1
1 reads out phrase sound pattern data corresponding to the pressed key one by one from a pattern data memory 10 storing plural kinds of phrase sound pattern data corresponding to the keypad 2a, and supplies it to the sound source circuit 12. . The data for one note consists of a key number N that determines the musical instrument, step time data S that determines the sound timing, and velocity data V that determines the strength of the keystroke. The musical tone control circuit 11 is
Each time the time axis counter reaches a step time, the key number N and velocity data V are derived to the tone generator circuit 12. The sound source circuit 12 converts the PCM signal corresponding to the key number into a waveform R.
The data is read from the OM 13, amplitude-modulated with velocity data, and then output to the D/A converter 14.

The end of the phrase sound pattern data is an end mark E, and when the read data reaches this end mark, the sounding of one phrase ends.

FIG. 3 is a flowchart for explaining the operation of the musical tone generation circuit of FIG. 2. First, in step 20, pad-on is detected, and in step 21, it is checked whether it is a phrase hit mode or a single hit mode. In single-strike mode,
At step 27, sound generation processing is performed and the process returns to the main routine. In the phrase striking mode, the pads 1a and 2a are distinguished in step 22, and if the pad 1a is on the left hand side, sound generation processing is performed in step 27.

When the pad 2a on the right hand side is operated, step 23 selects one of the corresponding phrase hitting pattern data.
The sound is called up and produced in the next step 24. Next, in step 25, the address is incremented by 3 bytes,
At step 26, it is checked whether it is an end mark or not. If it is not an end mark, the process returns to step 23 to call up the next one-note data. If an end mark is detected in step 26, the process is ended and the process returns to the main routine.

As described above, according to the electronic percussion instrument of the above-described embodiment, complex percussion phrases can be produced with simple operations without requiring a high degree of skill, and the instrument can be hung from the shoulder using the shoulder strap 3. , the percussion player can perform with the right and left hands as if playing a guitar, increasing the degree of freedom of movement of the percussion player during the performance.

[0015]

Effects of the Invention The electronic percussion instrument of the present invention is provided with a storage means that stores percussion pattern data for a plurality of phrases, each phrase consisting of a plurality of percussion instrument tone strings, in association with a plurality of keypads. In response to an operation, the drum pattern data of a corresponding phrase is called up and sent to the sound source circuit, and in response to other keypad operations, the drum sound data of a single hit sound is sent to the sound source circuit. be. Therefore, complex percussion patterns or percussion phrases can be easily produced without requiring a high degree of skill. Furthermore, by a series of keypad operations, different percussion patterns or consecutive combinations of percussion phrases can be produced, allowing improvisational percussion performance.
