Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to newly generate performance information having a plurality of musical effects based on simple performance information generated by human body expression (performance). , Musical instruments and electronic musical instruments for expanding musical expressions.

[0002]

2. Description of the Related Art Conventionally, musical instruments have been indispensable for playing music other than vocal music, and each musical instrument has been improved by its physical characteristics and progressed, as well as musical works created by composers. In addition, it was created under the constraint of being within the range of musical instruments existing in that era.

[0003]

However, for a player who handles musical instruments, there are playing methods peculiar to individual musical instruments.
In addition, due to the physical and athletic limits of human beings, various restrictions have been placed on music generation.

For example, wind instruments such as flutes, trappets, shakuhachi, etc. have been basically used as music materials under the condition of a monophonic instrument in order to use both hands with fingers and to hold an instrument. In addition, it is difficult to add subtle changes to individual musical tones even in compound instruments such as a guitar, harp and piano, so a group of musical tones have been played together as chords.

Further, in electronic musical instruments such as electronic organs, synthesizers, and samplers, a plurality of tone color sequences can be handled electronically at the same time, but since the conventional keyboard is used for human operation, the tone colors are actually changed. Switching and playing were separate. Also, in an automatic performance system that uses a computer such as an automatic performance device and sequencer, it has become possible to describe musical sounds with subtle nuances individually at the stage of creating and editing performance data in advance. However, there was a drawback that the important elements of music, such as the interaction with real-time performance and the contingency and improvisation, were missing.

As a new musical instrument, various electronic musical instruments have been proposed which detect movements and angles of human limbs with various sensors and reflect them as parameters of a sound source such as an oscillator. Since it does not have the expressive power, it has not been adopted enough as a material for music.

The present invention has been made in view of the above-mentioned drawbacks. The performance information having a simple structure is obtained by detecting a physical expression (performance) of a human, and this is used as a basic material. While using it, spatial and temporal effects that were difficult with conventional musical instruments
Expanding expressiveness such as reverberation effect, reverberation effect, and complication of music components, and expanding musical possibilities such as real-time generation of new strings, melody, and harmony corresponding to basic materials It is intended to provide electronic musical instruments with rich musicality that have the potential to be realized.

A plurality of types of new performance information corresponding to basic performance information using performance as a material are generated and output in real time.

Another feature of the present invention is that

In such a system, as shown in the upper part of FIG.
When basic performance information corresponding to the physical movements of the performer is input, performance information such as an echo machine is obtained when individual performance information is generated, as if the volume gradually decreased after a certain period of time. . Since the on / off information storage circuit 9 handles each on / off information as separate performance information, there is no effect even if the outputs of the generation of individual performance information overlap.

In this case, in conventional devices such as digital reverb and digital echo, the sound volume is attenuated and the noise component due to the quantization error is increased, so that the S / N ratio is deteriorated particularly in a small sound volume. However, even if the volume information supplied to the sound source is reduced, the S / N ratio does not deteriorate if the sound source side performs sufficient bit precision calculation. .

Further, not only simple decrease and simple increase but also arbitrary time difference and arbitrary volume change can be set, so that reverberation and reverberation are much more complicated and wider than those of the conventional effect device. The potential of the effect is expanded. This functions as a new electronic musical instrument with a more delicate musical tone signal by positioning the generated performance information as reverberation / echo with a complicated structure, which is a drawback of conventional electronic musical instruments. In addition to breaking down the flatness of musical expression ability, it also contributes to the creation of new music formats by such expression media.

FIG. 16 is an explanatory diagram showing an example of another operation of the electronic musical instrument according to this embodiment having the configuration shown in FIG. Here, as the parameters set in the relative pitch information storage circuit 7 and the relative time information storage circuit 6,
Generation of multiple types of new performance information is assigned from the basic performance information at predetermined time intervals, and a predetermined value is set for each relative pitch information, so that a new sound corresponding to the basic performance information is generated. I'm trying to generate columns.

First, when one note of basic performance information corresponding to the physical movement of the performer as shown in FIG. 9A is input to such a system, 16 notes are generated in each performance information generation. A tone train in which the pitch rises by a semitone is generated at fixed time intervals such as a quarter note, and the twelfth performance information is a pitch one octave above the basic performance information. The sound sequence as if it became is played as the entire system.

Next, as the music progresses, the performer passes through the parameter writing circuit 16 in a predetermined format,
It is assumed that the control information for changing the relative time information and the relative pitch information is transmitted. Here, when one note of basic performance information corresponding to the physical movement of the performer as shown in FIG. 7B is input, the time of the eighth note after the quarter note has elapsed in the generation of individual performance information. A pitch-related sound train is generated as shown in FIG.

It can be said that this is a kind of blue note scale ad lib phrase, and the music information detected from the body movements of the performer has a sufficient musical content only by performing a simple performance corresponding to the fundamental tone. Abundant development will be played as the entire system. As described above, the conventional electronic musical instrument has an advantage that a plurality of types of phrases, which are stored in a large amount in the ROM and only selected, can be freely set by the parameter writing circuit 16.

Since it is possible to set an arbitrary time difference and an arbitrary pitch change in addition to a simple equidistant note sequence and a simple semitone scale, it is much more complicated than the conventional obligato generation function by an electronic musical instrument. Widely expands the possibility of effects of tone generation and melody generation. This functions as a new electronic musical instrument with a wider variety of performance outputs, in which the generated individual musical performance information is added as a new musical element as a whole. In addition to breaking down the flatness of musical expression ability, it also contributes to the creation of new music formats by such expression media.

FIG. 17 is an explanatory view showing an example of another operation of the electronic musical instrument according to this embodiment having the configuration shown in FIG. Here, all the relative time information set in the relative time information storage circuit 6 is <zero>, that is, a plurality of pieces of performance information are generated almost simultaneously with the basic performance information, and are set as parameters set in the relative pitch information storage circuit 7. ,
By assigning the generation of performance information of multiple types of new pitches that are separated from the pitch of the basic performance information by a predetermined interval,
A new chord corresponding to the basic performance information is generated.

When one note of the basic performance information corresponding to the physical movement of the performer as shown in the upper part of the figure is input to such a system, the individual performance information is individually set in the generation of the performance information. Performance information according to the relative pitch is generated, and performance information having a chord structure is played as a whole system from basic performance information of a single note. Musically, it can be said that it is a kind of poising technique or harmonization technique, and the music information detected from the body movements of the performer is a simple musical performance equivalent to the reference tone, and the music content is sufficient. The rich development of will be played as a whole system.

As described above, the conventional electronic musical instrument has the advantage that a plurality of types of chords, which are stored in a large amount in the ROM and only selected, can be freely set by the parameter writing circuit 16. Further, since it is possible to set an arbitrary pitch change that is not limited to a simple semitone scale, the possibility of chord generation effect is expanded in a much more complicated and wide range than the chord generation function of the conventional electronic musical instrument.

This is to function as a new electronic musical instrument having a wider variety of performance outputs, in which the generated individual musical performance information is added as a new musical element as a whole. In addition to breaking down the flatness of the musical expression ability that is, it also contributes to the creation of new music formats by such expression media.

FIG. 18 is a block diagram for explaining the operation of the performance operation information generating circuit 1 shown in FIG. In the figure, 40 to 44 are sensors, 45 is a data selector, 4
6 is an analog-digital converter, 47 is a ROM, 48
Is a RAM, 49 is a port, 50 is a CPU, and 51 is a system bus. That is, the CPU 50 is the system bus 5
It operates according to the program of the ROM 47 connected by 1, and stores necessary parameters and data in the RAM 48.

The sensors 40 to 44 are for detecting the physical movement of the performer, and are appropriately selected from those corresponding to various physical quantities as described above in accordance with the form of performance. The detection signals from the sensors 40 to 44 are time-divisionally selected by the data selector 45, and are converted into digital data that can be handled by the CPU 50 by the analog-digital converter 46 synchronized with this. The performance information, control information, and parameter setting information finally generated by the CPU 50 are stored in the port 4
9 is written into the basic information detection circuit 3, and this output is taken into the basic information detection circuit 3 at a necessary timing.

FIG. 19 is a flow chart for explaining the operation of the block diagram shown in FIG. That is, when detecting the state of a sensor among a plurality of sensors, the data selector 45 is selected by first specifying the sensor selection.
Supplies the signal from the corresponding sensor to the analog-digital converter 46. Here, when the analog-digital conversion output data is input via the system bus 51, this is used as new data for this time and compared with the previous old data of the corresponding sensor stored in the RAM 48. If both data match, there was no event,
Since there is no need to update the data, this process ends and the next process starts.

On the other hand, if the new data and the old data do not match, it means that the physical expression of the performer related to this sensor has occurred, and the processing corresponding to the value of this new data and the type of sensor. Branch to. For example, if a certain value is exceeded, it is considered that the musical tone of a predetermined pitch, volume, tone color, and tone generator sequence is generated, and performance information of a predetermined format is set, and this is transferred to the port 49 via the system bus 51. To do. When a certain sensor exceeds a certain value, control information of a predetermined format is set as pitch bend information, and this is transferred to the port 49 via the system bus 51.

When both a certain sensor and a certain sensor reach a certain value, the parameter writing circuit 1
Parameter setting information of a predetermined format such as setting a predetermined parameter via 6 is set, and this is transferred to the port 49 via the system bus 51. After the above-described necessary information generation processing, the new data of this time is stored in a predetermined address of the RAM 48 for the next comparison, the processing relating to this sensor is terminated, and the next processing is performed.

As described above, by associating the output states of the sensors 40 to 44 with the performance information, control information, and parameter setting information by the program of the CPU 50, the individual difference with respect to the physical action of the performer is corrected, and if necessary. It is possible to deal with the expansion and simplification of the system without changing the hardware, and the degree of freedom of the system is greatly improved.
