DESCRIPTION OF THE PREFERRED EMBODIMENTS

1. Description of Functional Block Diagram An embodiment of the present invention will be described with reference to the drawings. The music data generation device 1 shown in FIG. 1 includes a component music data storage unit 8, a music data generation unit 7, a state change detection unit 3, an input data generation unit 5, and an output unit 9.

The component music data storage means 8 stores a plurality of component music data of unit length. Each of the component music data is data that can be connected musically without a sense of incongruity even when music generated based on any two pieces of component music data is continuously performed. In the present embodiment, the basic chord melody data and the sub chord melody data which can be musically combined with the basic chord melody data are employed. Further, the data at the end of each melody data is composed of data that is easily connected to other melody data.

The state change detecting means 3 detects a state change of the living thing. The input data generation means 5 generates the input data based on the detected state change.

The music data generating means 7 specifies one of the component music data based on the given basic input data and the sub-input data sequentially given after the basic input data, and Music data is generated based on the component music data.

Further, the music data generating means 7 generates the music data by transposing the melody data based on the first input data as the transposition determining data and the transposition determining data. Further, input data provided after a predetermined time has elapsed is used as transposition determination data, and the degree of transposition of each of the component music data is changed based on the transposition determination data. If the detected input data exceeds the range of one octave, the input data is generated by shifting the octave to the input data of one octave.

The output means 9 outputs the generated music data.

2. 2. Hardware Configuration FIG. 2 shows an example in which the music data generation device 1 shown in FIG. 1 is applied to a flower music box that plays music according to the state of a plant. Flower music box 10 is CPU
1 is an example of a hardware configuration realized by using.

The flower music box 10 includes a CPU 23,
Memory 27, hard disk 26, CRT 30, FDD
25, a keyboard 28, an input / output interface 32, and a bus line 29.

The CPU 23 controls each unit via the bus line 29 according to a control program stored in the hard disk 26.

This control program is transmitted via the FDD 25 to the flexible disk 25 storing the program.
a and is installed on the hard disk 26. In addition to the flexible disk, a hard disk may be installed from a computer-readable storage medium in which a program such as a CD-ROM or an IC card is substantially integrated. Furthermore, you may make it download using a communication line.

In the present embodiment, the program is installed from the flexible disk to the hard disk 26 so that the computer can indirectly execute the program stored in the flexible disk. However, without being limited to this, the program stored in the flexible disk is stored in the FDD25.
Alternatively, it may be executed directly from. In addition, as a program executable by a computer, not only a program that can be directly executed by installing it as it is, but also a program that needs to be temporarily converted into another form (for example, decompress a program that has been compressed). ),Furthermore,
Also includes those that can be executed in combination with other module parts.

The memory 27 has a fundamental tone buffer 27a and a sub tone buffer 27b. The memory 27 also stores various calculation results and the like. The selected genre and the like are displayed on the liquid crystal display unit 30.

A state detection sensor 36 is connected to the input / output interface 32 via an AD converter 34. Also, the tone generator circuit 3 is output via the MIDI playback circuit 38.
7, an amplifier 39 and a speaker 40 are connected.

FIG. 3 shows the details of the state detection sensor 36.
This will be described with reference to FIG. The state detection sensor 36 includes the detection unit 5
1. The differential amplifier 53 and the FET 55 are provided.

The detector 51 detects the change in the state of the plant 60
0a is detected without contact. Specifically, the detection unit 51
Is a differential detection circuit having an electromagnetic wave generator 51a, an electromagnetic wave detector 51c, an electromagnetic wave generator 51b, and an electromagnetic wave detector 51d. The measured values obtained from the electromagnetic wave detection unit 51c and the electromagnetic wave detection unit 51d are given to the CPU 23 when the difference between the two values is detected by the differential amplifier 53 and amplified by the FET 55.

The hard disk 26 has a DB shown in FIG.
A box number determination table is stored. This is a correspondence table for determining the number of the data box used when transposing based on the values of the first sound (fundamental sound) and the second sound (secondary sound).

FIG. 5 shows a file structure of data specified by the DB box number. Thus, the database box is divided into boxes 1 to 8 according to genre. Furthermore, each box stores 100 parts as part music data. In the present embodiment, a melody (melody) for 4 seconds is employed as the component music data. With regard to the melody for four seconds, the note at the end is lengthened (half note or the like) or shortened (eighth note or the like) so as to be easily connected to other component music data.

3. Next, a program stored in the hard disk 26 will be described.

Here, the case where the detection data as shown in FIG. 6 is given from the state detection sensor 36 will be described. In FIG. 6, the horizontal axis represents time, and the vertical axis represents voltage (mV).

The CPU 23 first performs initialization (step ST1 in FIG. 7). Next, data is taken in (step ST3). Specifically, the value detected by the state detection sensor 36 is digitized by the AD converter 34 and stored in the memory 27 via the input / output interface 32.

Next, the CPU 23 determines whether or not I = 1 (step ST5). In this case, step ST1
Is set to I = 0. Therefore, the process proceeds to step ST31 in FIG. 8, and it is determined whether or not n = 0. In this case, since n = 0 in step ST1 in FIG. 7,
The process proceeds to step ST33 to perform MIDI conversion of the input data (step ST33). Specifically, the given detected value is converted into MIDI note numbers (numbers representing musical scales) represented by "21" to "108" on the piano 88 keyboard.

Next, it is determined whether or not the note number converted in step ST33 belongs to "60" to "71" (step ST35). If not, an octave shift process is performed (step ST37). This is because the processing is performed in the range of one octave as described later.

For example, if the MIDI note number obtained by converting the input data is as low as "21", it is shifted up by 4 octaves and shifted to "69" by octave. Conversely, if the MIDI note number obtained by converting the input data is as high as "79", the MIDI data is shifted down by one octave to the octave "67". In step ST35, “6
If the MIDI note number belongs to “0” to “71”, it is not necessary to perform the process of step ST37.

In this way, whether the converted note number does not belong to “60” to “71” or does not,
The CPU 23 stores any one of the note numbers “60” to “71” as a fundamental tone (step ST39).

Next, the CPU 23 increments the flag f (step ST41), and proceeds to step ST6 in FIG.
Proceed to 3 to increment n.

Next, the CPU 23 determines whether or not n = 20 (step ST65). In this case, since n = 0, the process proceeds to step ST71 to determine whether 0.2 seconds have elapsed.

When the CPU 23 determines that 0.2 seconds have elapsed, it takes in data again (step ST in FIG. 7).
3). Thereafter, as before, the CPU 23 proceeds from step ST5 in FIG. 7 to step ST31 in FIG.
Since n = 1, the process proceeds to step ST63 in FIG. 9, where n is incremented.

The CPU 23 determines whether n = 20 (step ST65). In this case, since n = 2, the CPU 23 proceeds from step ST65 to step ST65.
The process proceeds to step ST3, and after 0.2 seconds, step ST3 is performed again.
The following processing is performed.

In this way, after the first input data is input and stored as the fundamental tone, 4 seconds (0.2 seconds.times.
20) The above processing is repeated until the lapse of time.

The processing when four seconds have elapsed will be described. In this case, since n = 20 in step ST65, C
The PU 23 sets n = 0 (initialization) (step ST6)
7). Next, the CPU 23 sets I = 1 (step S
T69).

Next, the CPU 23 proceeds to step ST71.
When it is determined that 0.2 seconds have elapsed, data is loaded (step ST3 in FIG. 7). Then, the CPU 23
In step ST5, it is determined whether or not I = 1. In this case, since I = 1 has been set in step ST69,
The process proceeds to step ST7 to determine whether n <5.

In this case, since n = 0 in step ST67, the CPU 23 determines that n <5 and proceeds to step ST9.

In step ST9, the CPU 23 sets n =
It is determined whether it is 0 or not. In this case, since n = 0 in step ST67, MIDI conversion of the input data fetched in step ST3 is performed (step ST11). In the processing in step ST11, step ST11
33, step ST35 and step ST37, and the description is omitted. That is, if the input data requires octave processing, octave processing is performed.

Next, the CPU 23 executes the obtained MIDI
Is stored as a secondary sound (step ST1).
7). Since the fundamental tone has already been determined in step ST61 in FIG. 9 and the sub-tone has been determined in step ST17,
The CPU 23 determines the DB box number and the component number in step ST19, and also determines the transpose amount (step ST19). Specifically, it is determined as follows.

For example, when the fundamental tone is “63” and the secondary tone is “6”
7 ”, the vertical direction“ 63 ”and the horizontal direction“ 67 ”
"1" is obtained at the position where. Therefore, C
The PU 23 selects the DB box number “1”. Further, a transposition amount “plus 3” is obtained. Note that a random number is generated for the part number, and
Select one of up to "100". In this way,
The data box number, the part number, and the transpose amount are determined.

Next, a drum part is determined (step ST21). The drum part is determined as follows. The hard disk 26 previously stores a plurality of rhythms for each genre, such as 4 beats for popular and 3 beats for waltz. Then, "Popular" is stored in the memory 27 as a default genre in advance.
Is stored. Therefore, this may be read out. The genre can be changed by the operator using the keyboard 28 (see FIG. 2).

Next, the CPU 23 determines whether or not n = 4 (step ST25 in FIG. 7). In this case, since n = 0, the process proceeds to step ST63 in FIG. 9 and n is incremented. Next, the CPU 23 determines whether or not n = 20 (step ST65). In this case, since n = 20, the process proceeds to step ST71, and it is determined whether 0.2 seconds have elapsed (step ST71). If it is determined that 0.2 seconds have elapsed, the process proceeds to step ST3, and data is fetched.

Next, the CPU 23 determines whether or not I = 1 (step ST5). In this case, since I = 1, the process proceeds to step ST7, and it is determined whether or not n <5. In this case, since n = 1, the process proceeds to step ST9, where n =
It is determined whether it is 0 or not. In this case, since n = 1, the process proceeds to step ST25, and it is determined whether or not n = 4.

In this way, data is taken in step ST3 until n = 4. That is,
Data acquisition is performed five times every 0.2 seconds.
Since n = 4 when performed five times, from step ST25,
The process proceeds to step ST50 in FIG.

In step ST50, the CPU 23 determines whisper data of a flower. Specifically, the five data captured every 0.2 seconds in step ST3 are
The data is converted to IDI note number and the sound is used as it is. By adding the flower whisper data, it is possible to provide music data that reflects any change in the state of the plant.

If n ≧ 5 in step ST7, the whispering process of the flower is not required,
Then, the process proceeds from step 7 to step ST63, and the processing of step ST63 and subsequent steps is performed.

When the process in step ST50 in FIG. 9 ends, the CPU 23 generates MIDI data (step ST51). Specifically, step ST1
9. A file in the MIDI format is created based on the data obtained in steps ST21 and ST50. The created MIDI data is output to the MIDI reproducing circuit 38 via the input / output interface 32 shown in FIG. In this embodiment, music in which flower whisper data for the first second is added to the melody and drum part for four seconds is generated.

The MIDI reproduction circuit 38 converts the given MIDI data into a music signal based on the sound source stored in the sound source circuit 37 and supplies the music signal to the amplifier 39. Amplifier 3
9 amplifies this and outputs it from the speaker 40. Thereby, the music for four seconds is output from the speaker 40 with a delay of five seconds from the start. This is because it takes 4 seconds after the fundamental tone is obtained to obtain the auxiliary sound, and 1 second is required as the whisper data of the flower.

Next, the CPU 23 increments the flag f (step ST55 in FIG. 9) and determines whether or not the flag f = 8 (step ST57). In this case, since the flag f = 1, the processing from step ST63 is performed.

In this way, the auxiliary sound is determined every four seconds, and the data box number is determined based on the already determined fundamental sound and the sequentially obtained auxiliary sound. In addition, when deciding a sub-sound, flower whisper data is decided.

When such processing is repeated eight times, the CPU 23 determines in step ST57 that the flag f = 8
Is determined, and the flag f is initialized in step ST59. Then, the data stored in the current auxiliary tone buffer 27b is used as the fundamental tone data as the fundamental tone buffer 27a.
(Step ST61). Thereafter, step ST
The processing of 63 and below is repeated. Thus, when the flag f = 8, the last sub-tone is changed as the fundamental tone.

This processing will be described with reference to FIG. In FIG. 10, the whisper data of the flower is omitted. When the data as shown in FIG. 10 is detected, the note number “70” at time t0 is changed from the note number “68” at time t1 to the note number “64” at time t8, which are eight sub-tones. It becomes the fundamental tone. The last (eighth) sub-tone is the base tone of the next part. Therefore, the note number “63” at the next time t9 or later becomes the secondary sound, and the DB box number,
The transpose amount is determined. Thus, after a group for one fundamental is selected eight times every four seconds,
By determining the last sub-note as the fundamental tone of the next group, it is possible to provide a variety of music one after another.

Further, in the present embodiment, by transposing the component music data shown in FIG.
In any of the DI note numbers “60” to “71”, music data corresponding to the note numbers can be generated. Therefore, it is possible to provide music that is rich in variability.

That is, the transpose amount is determined based on the fundamental tone, the DB box number is determined based on the auxiliary sound, and the component music data divided into the DB box number is determined. For example, if the sub-tone is "64" and the fundamental tone is "66", the original melody of Dm7 is transposed by plus 4 and output as the melody of F ^# m7.

By transposing in this way, if there is only an area for storing only the data of the fundamental tone 60,
Music data corresponding to all of the fundamental sounds "60" to "71" can be generated. That is, the component music data belonging to all the codes can be generated without storing all the component music data of the codes shown in FIG.

4. Other Embodiments In this embodiment, the amount of transposition is determined by the value of the fundamental tone. Then, which DB box number is designated by the value of the sub sound is determined. However, the method of determining the DB box number is not limited to this, and the DB box number may be determined based on the amount of deviation between the fundamental sound and the auxiliary sound. Alternatively, it may be determined based on the value change rate of the fundamental sound and the sub-sound, the change rate in a predetermined time, the frequency of the electromagnetic wave to be detected, the change degree thereof, and the like.

The transposition amount and the DB box number may be determined by random numbers without using the correspondence table shown in FIG.

Further, even if the component music data stored in each DB box number is continuously performed with the component music data stored in another DB box number, the component music data may be musically continuous. Since the data is data, no matter which part music data is selected, it is possible to play music that does not cause any discomfort to the listening person.

Since the fundamental tone is changed every 4 seconds × 8 times, music having a completely different chord may be generated thereafter. However, if the music of one chord and the chord that musically matches this chord is played for about 30 seconds, then even if the music changes suddenly,
The performance is not so uncomfortable.

In this embodiment, an electromagnetic wave sensor is used as a sensor, but an infrared sensor may be used. Further, the concentration of oxygen generated by high synthesis of plants or the concentration of consumed carbon dioxide may be detected.

In this embodiment, a differential electromagnetic wave detection sensor is used. However, as shown in FIG. 12A, a detection unit 71 for detecting a bioelectric current of a plant without contacting leaves may be used. In addition, as shown in FIG. 12B, this may be detected at the stem. Further, as shown in FIG. 12C, this may be detected at the flower portion.

Further, the tone of the music may be changed according to the change in the state of the flower. For example, by shifting the octave, MIDI already within one octave
Although the conversion is performed so that data can be obtained, a certain threshold value may be provided, and when the current decreases, the tempo of the performance may be reduced. In addition, switching may be performed so that dark music is selected for the component music data of the stored data. In addition, as the component music data, data obtained by reducing the types of musical instruments or data having a low sound as a whole may be employed. Further, the drum may not be performed in step ST21.
Thereby, music based on the detected state change can be generated.

In this embodiment, a case where a change in the state of a plant is detected has been described. However, input data obtained from other organisms may be used as long as a random value can be obtained to some extent.

In this embodiment, the genre is changed using the keyboard, but a changeover switch may be provided.

Even if the data has regularity, it is possible to play a variety of music by shifting the detection timing.

In this embodiment, a change in state of a plant is detected without contacting the plant. Therefore, music can be played without damaging the plant (non-destructive). The state change detecting means may be a means for detecting other than a bioelectric current, or may be a means for detecting a state change by contacting a plant.

Further, music may be detected by detecting the speed and intensity of a key input by a human from the keyboard 28 shown in FIG. Thus, when the human condition is calm, calm music can be played.

In the present embodiment, the data is transmitted as it is for the whispering sound of a flower. However, the length of the note is appropriately shortened so that the music becomes continuous music such as an eighth note or triplet. It may be.

Further, in the present embodiment, the whispering process of the flower is performed at the stage when the five data are prepared (step ST7 in FIG. 7).
25: yes), but may be performed after step ST21.

Although the data amount is reduced by transposing, any music may be used as long as the music selected based on the fundamental tone and the sub-tone changes.

In this embodiment, eight types of DB box numbers are prepared. However, the number may be 12 octaves. However, the number of DB box numbers is not particularly limited.

In each box, code "C"
"F""G7""D7""Am""Dm7""Cm""F
m), but the melody stored in each phrase number can be any melody based on the structure of music that humans can hear without discomfort when connected. Good.

Further, in the present embodiment, each component music data includes the main melody, the sub melody, the chord, the bass, and the like. However, the component music data may include only the melody.

Further, since the electromagnetic wave sensor detects the dielectric constant of a plant, the data fluctuates according to the amount of water contained in the leaves or stems. This makes it possible to reliably detect a change in the state of the flower.

In the present embodiment, the functions shown in FIG. 1 are realized by using the CPU 23 and software. However, some or all of them may be realized by hardware such as a logic circuit.
