Description

[Detailed Description of the Invention] This invention provides data related to the performance of music (music data).
The present invention relates to an automatic performance device that automatically performs music based on music, and particularly relates to an automatic performance device that reproduces animal sounds during the performance process to be useful for children's t-d music lessons.

Conventionally, automatic performance devices store pitch data indicating the pitch of each note composing a song and note length data indicating the note length, and sequentially read these data at the beginning of the song to play the corresponding musical tone. There is something that is designed to generate this. By the way, the songs that children are particularly interested in are those in which animal sounds are inserted as part of the music (for example, "Kakkou", whose musical score is shown in Figure 1, or "Neko Funjatta", shown in Figure 2).
etc.), but if this type of music could be played back by an automatic performance device, it would be very useful for children's music lessons.

This invention was made in view of the above circumstances, and its purpose is to provide an automatic performance device that is useful for children's music lessons, etc. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows an embodiment in which the automatic performance device according to the present invention is configured to play music using animal sounds and scale names (do, shi, mi, . . . ).

It is a lock diagram.

The automatic performance device shown in this figure has music data that is a combination of data specifying an animal's voice, data indicating the pronunciation length and note length of the same voice, data specifying the scale name, and data specifying the scale name. A music data memory 1 is provided in which combination data with data indicating the note length of the music data is stored, and an audio data memory 2 is provided in which audio data of each animal's voice and audio data of each scale name are stored. The readout control unit 3 (succession control means) reads each of the combination data from the song data memory 1 in the order of progression of the song, uses these read data to read the corresponding audio data from the audio data memory 2 each time, and further The read audio data is played back by the playback unit 4, for example, as a cuckoo.

It was made to be pronounced like cuckoo, shi, do, shi, do, cuckoo, etc.

Describing each part of this embodiment in detail below, the audio data memory 2 contains audio data of the sounds of each animal (katsukou, dog,...) and audio data of each floor name (do, shi, mi,...). This is a read-only memory IJ (ROM) in which data is stored. In this audio data memory 2, audio data of dog barking is stored using a predetermined number of addresses after block $, and audio data of dog barking is stored using a predetermined number of addresses after address <Lw>. The audio data of ``C'' is stored using a predetermined number of addresses starting from the address <Ld>, the audio data of ``C'' is stored using a predetermined number of addresses starting from the address <Lr>, Similarly, sounds of other animals and audio data of other scale names are stored respectively. The music data memory 1 is composed of a ROM having multiple storage areas corresponding to the multiple music pieces handled, and each of these areas stores music data for seven corresponding songs (for example, "Kakko"). data AD specifying an animal's sound or floor name;
The data is stored in the progression order of the song using data in combination with data LND specifying the note length of the voice or scale name. In this case, the data AD refers to the starting address (any one of <Lk>, <Lw>, -, <Ld>, <Lr>, -) of the storage part of the corresponding audio data in the audio data memory 2. Address data is used, and the data LND is the number of unit times when the tempo clock TCLK output from the tempo generator 5 is taken as a unit time. Further, data AD is stored using predetermined bits on the upper side of the corresponding address, and data LND is stored using the remaining bits on the lower side of the corresponding address. Further, each of the areas for storing music data has a well-defined start address such that the lower predetermined bits of the address data indicating the start address of each area are all zero. Here, the format of the music data actually stored in this musical instrument data memory 1 is shown in FIG. 9 using the storage area of the song "Kakko" in FIG. 1 as an example. In the figure, the starting address of this area <1
> contains the value "Lk" indicating the address <Lk> corresponding to the first sound "cuckoo" of this song as data AD, and the value "Lk" indicating the address <Lk> corresponding to the first sound "cuckoo" of this song as data LND, and the value "Lk" indicating the address <Lk> corresponding to the first sound "cuckoo" of this song as data LND. Since the note length corresponds to , "N-" is stored in each case. In this case, the length of a whole note is N times the period of the tempo clock TCLK. Also, the first address <t+X> of this area contains data A.
As D, the value rOJ indicating the next rest of the first voice "cuckoo" of this song is stored, and as data LND, +i [t, t J is stored since the homogeneous mark is a g rest. . 2. From the address (A+2>) onward in FIG. 9, the values rLkj, ro'', rL are similarly set as data AD.
rJ, rLa-J.

. . . are stored respectively, and the values are also stored as data LND.

Next, in FIG. 3 again, the song selection switch 6 is a switch for selecting music data of a desired song from among the music data of a plurality of songs stored in the music data memory 1. When the operator selects a desired piece of music using the song selection switch 6, selection data As for selecting all areas where the song is stored is output and supplied to the music data memory 1.

Then, the readout control section 3 sequentially reads music data from the area selected by the selection data As in the music data memory 1.

Hereinafter, in this continuous output control section 3, the retrieval circuit 7 is a circuit that reads out data from a predetermined location in a selected area in the music data memory 1, and this readout circuit 7j, -1
When the start switch (momentary switch) 8 is turned on and the signal 5TTitT75?1'' is reached, the operation starts.First, the address counter 7a is cleared to zero.The output of the address counter 7a is stored in the music data memory 1 as the address data A1. Here, the song selection switch 1゜tchi 6 selects the song ``fJ one trick''
If is selected, the selection data AS selects the area shown in Figure 1, so the data at address <1> shown in Figure 1 is read out. Of the data at address <1>, data AD, that is, the value rLkj, is supplied to an adder circuit 9 and an audio data readout circuit 10, which will be described later, by a note length counter 11-1. The note length counter 11 has a counter and a comparator, and starts counting the tempo clock TCLK from the time when the data LND starts being supplied, and the counted value of the tempo clock TCLK is used as the data L, N. When it matches D's 1st shift (in this case, ")"), a signal NEXT (1 pulse signal) is output, and at the same time, the count value of the tempo clock is returned to zero. In other words, this note length color/return signal 11 generates a signal N E :(
Output T. This A word NEXT is supplied to the successive output circuit 7. When the successive circuit 7 is supplied with this signal NEXT, it increments the address counter 7a. This result - address of song data memory 1 <,, 1+
1 > data is read. Then, an operation similar to the one described above is repeated.

However, according to this succession control unit 3, each data (data consisting of data AD and data LND) in the area corresponding to the selected song in the song data memory 1 is arranged in the order of progression of the song and according to the valley note length. They are read out sequentially at the specified timing.

On the other hand, when the start switch 8 is turned on, the signal 5TRT (1)/rus signal) is the OR gate 1.
2 to the delay circuit 13 - this delay circuit 1
3 is the total time from when the signal 5TRT (or signal NEXT) is supplied to the readout circuit 7 until the address signal A1 is output, and when the address signal A1 is supplied to the music data memory 1 and the data is output. This is to compensate for the delay time when 1 is read. In this case, the signal 5TRT is delayed for a predetermined time by the delay port @13 and then supplied to the audio data reading circuit 10. The audio data reading circuit 10 is the music data memory 1
This circuit reads out the corresponding audio data based on the data AD read out from the delay circuit 13, and includes an address counter 10a, a comparator, etc.
It is designed to be activated when No. 1'm is supplied. Now, the delay circuit 13 is 1 corresponding to the signal 5TRT.
When the signal is output, the audio data reading circuit 10 clears the address counter 10a to zero, and outputs the output of the address counter 710a as address data A2. The adder circuit 9 adds the data AD supplied from the music data memory 1 (in this case, S rLkj) and this address data A2 (in this case, ?1 r Oj > and f 7jl).
% and address data A3 (in this case, VLk+Qj
=lLkj and tQc> are created and supplied to the audio data memory 2. As a result, the voice data memo address 920
Lk> data (first sound P element data of "Katsupura") is read out. Next, the address counter IOY is incremented by the voice mark L+the hanging glue φ, and thereby the address data A2 becomes "
1”.

As a result, data at address Lk+1> of the audio data memory 2 is read out in the same manner as described above. Thereafter, in the same manner, the audio element data at each address after address <Lk+2> of the audio data memory 2 is sequentially read out every clock φ. Then, when the output of the address counter 10a reaches a predetermined value determined by the data AD (this value is the number of audio element data of each audio data, that is, the number of addresses to be read, and differs depending on the type of audio), the audio data continuous output circuit 10 stops.

In this way, the audio data corresponding to the first voice ``Cuckoo'' of song 1, ``Katsukou'', is read out.Next, when the note length of this first voice ``Riki・Tsukou'' has elapsed, the signal NEXTd' When you are kidnapped, the same signal NEXT
is supplied to the delay circuit 13 via the OR gate 12.

As a result, the audio data reading circuit 10 is activated again.

However, in this case, since the data AD has the value "0", that is, it is a rest, no audio data is read out.Next, when the note length of this rest has elapsed and the signal NEXT is output again, the audio data The read circuit 10 is activated again. In this case, since the data AD is the value rLkJ, the audio data corresponding to the audio "cuckoo" is read from the audio data memory 2.

Similarly, the audio data reading circuit 10 receives the signal NEXT.
is activated every time AD is generated, and the audio data indicated by the data AD at that time is read out from the audio data memory 2.

Each audio element data of the audio data read out from the audio data memory 2 in the above manner is supplied to the D/A converter 14 and converted into a corresponding anacog signal, and further amplified by the amplifier 15 and sent to the speaker 6. supplied to

□.

According to this embodiment, when 6D, for example, selects the Ldll "Katakou" and starts playback, the music data shown in FIG. 9 is extracted, and accordingly, the music data shown in FIG. The audio of I:J ni Gatsuko 2 and the floor name shown in is played back. Note that in this -X5 diagram, the shaded portions each indicate a silent period.

Next, FIG. 6 is a block diagram showing the configuration of an electronic organ equipped with another embodiment of the automatic performance device according to the present invention. The embodiment shown in this figure reproduces the same song using animal sounds and normal instrument sounds (automatic performance),
This system is configured to selectively play music (automatic performance) using animal sounds and scale name voices.

Note that in FIG. 6, parts corresponding to those in FIG. 3 are given the same reference numerals, and their explanations will be omitted.

In this embodiment, the keyboard 17 is the keyboard of this single child organ, and the key switch circuit 18 is in this case 117.
LglII@ is made up of key switches provided corresponding to each # (key) /pair/. Push'a detection circuit 19
In the key switch circuit 18, each key switch is moved and pressed *i, and the key code i that indicates each press is pressed.
(Outputs C-. On the other hand, tone selection switch 21) id
, is a switch for selecting an instrument sound (organ, piano, trumpet, etc.) desired by the operator, and this tone selection switch 20 outputs a tone code TC indicating the selected instrument sound. The musical tone signal forming circuit 21 inputs the key code KC and generates a tone source signal with a pitch corresponding to each pressed key, and also adds a tone code T to these tone source signals.
A musical tone signal is generated and outputted by adding the timbre of the musical instrument sound indicated by C. This musical tone signal is supplied to an amplifier 15.

However, in the above portion, when the performer operates the keyboard 17 to perform a performance, the speaker 16 generates the musical tone of the played song.

Next, the parts constituting the automatic performance device will be explained.

First, the audio data memory in this embodiment consists of an audio data memory 2 that stores audio data of animal sounds, and an audio data memory 2' that stores audio data of floor names. In the audio data memory 2, address <L
The audio data of Katsuko's voice with k> as the starting address is
Further, audio data of a dog's barking is stored with the address <Lw> as the first address, and similarly, audio data of other animals' vocalizings are stored. In addition, in the audio data memory 2', the audio data of C is stored with the address <Ld> as the first address.
Also, the audio data starting from the address <Lr> is
Similarly, audio data for other scale names are stored.

In addition, each area of the music data memory 1 contains music data of a corresponding music piece, including data AD/MKC that specifies the pitch of an animal's voice or a note, and data LND that specifies the note length of the voice or note. , said data A D / M K
The data is stored in the order in which the song progresses using data in combination with B from a bit for identifying whether C is data specifying an animal's sound or data specifying the pitch of a musical note. In this case, when specifying the sound of an animal, the data AD/MKC is the starting address (<L
k>, <Lw>.

...) still specifies the pitch of a musical note, the key code MKC (same code as the key code KC) of the key corresponding to the pitch is used; As data LND, the number of unit times when the tempo clock TCLK is taken as a unit time is used, similar to that shown in FIG. Also, the bit ID
B is 1'' if the data AD/MKC is the address data AD specifying the sound of an animal;
If MKC is a key code MKC that specifies the pitch of a musical note, it is determined to be "fo".B from the bit is set to the MSB of the corresponding address, and the data LND
uses the predetermined bits of LSBll at the corresponding address,
Further, data AD/MKC are each stored using the remaining bits of the corresponding addresses. Here, the fork cut of the music data actually stored in this music data memory 1 is shown using the storage area of "Song 1 Katakou" shown in FIG. 7 as an example. i Next, in Fig. 6, a switch (alternate switch) indicated by the reference numeral 22 is a selection switch for selecting whether to reproduce the instrument sound or the sound of the scale name.This selection switch 22 When is in the on state, the signal SYL is 1
When the signal SYL is in the OFF state, the signal SYL becomes a "0" signal and the playback of the musical instrument sound is selected. In addition, the switch indicated by reference numerals 23, 24, and 25 outputs the data supplied to the data input terminal ■ from the data output terminal A when the control input terminal SBQ and the "0" signal are supplied. Control input terminal SB bit 1"
When a signal is supplied, it is configured to be output from data output terminal B.

The reproduction operation when the song "Katsukou" is selected by the song selection switch 6 will be described below.

First, a case will be described in which a musical instrument sound is selected by turning off the selection switch 22. Now, the operator presses the start switch 8.
When turned on, the signal becomes 5TRT or 1, and the data at address <1> in the music data memory 1 is read out. Of this read data, pins 1-IDB are supplied to each control input terminal SB of the switch 23 and 24, data AD/IVIKC is supplied to the data input terminal I of the switch 23, and data LND is supplied to the control input terminal SB of the switch 23 and 24. It is supplied to the long counter 11. In this case, since the bit IDB is 1'', the data AD/MKC, that is, the value rLkJ read as data AD, is supplied to the adder circuit 9 and the audio data read circuit 10 via the switch a23. The signal 5TRT is supplied to the delay circuit 13 via the OR gate 12, where it is delayed for a predetermined time, and then supplied to the audio data readout circuit 10 via the switch 24. As a result, the audio data readout circuit 10 starts its operation and reads out audio data corresponding to "cuckoo" from the audio data memory 2. The read audio data is then supplied to the D/A converter 14 via the OR circuit 26. As a result, Katsukou's voice is played back. One-sided note length counter 1
1 is data LND, which measures a long time, and outputs a signal NEXT when this long time has elapsed.

When this signal NEXT is output, the music data memory 1
The data at address <t+1> is read out.

In this case, the bit IDB is ``, so the data AD/
MKC, that is, the code "0" read out as the key code MKC (the key code for a rest is "0") is sequentially passed through the switch 23, 25 to the musical tone signal forming circuit 21.
The supplied 8-tone signal forming circuit 21 uses this key code M.
Since KC is "0", no musical tone signal is generated, and therefore no musical instrument sound is reproduced in this case. On the other hand, the note length counter 11 is 1 read out as data L i'J D.
The note length of the one-minute rest is counted based on the direct ``7'', and when this note length has elapsed, a signal NEXT is generated.

Thereafter, in the same manner, each piece of data from address <t+2> onward in the music data memory 1 is sequentially read out according to the note length. In this case, for example, music data memory address 10 <t+4
> data is read, data AD/VIK
C-\", that is, the key code MKC read as data MKC is supplied to the musical tone signal forming circuit 21 via the switch 23, 25. Therefore, in this case, the musical instrument with the pitch of Sound is played.

- According to this embodiment, if the selection switch 22 is turned on and divided, the music stored in the music data memory 1 can be played back using animal sounds and musical instrument sounds.

Next, a case will be described in which the selection switch 22 is turned on and the voice of the scale name is selected.

In this case, after the start switch 8 is turned on, the process in which each piece of data from address <t> onward in the music data memory 10 is read out sequentially according to the note length is the same as the operation described above. The above-mentioned operation also occurs when the data AD/MKC read from the music data memory 1 is data AD specifying the sound of an animal, that is, when data such as obi area <1>, <1-+2>, etc. is read. In the same manner as above, the audio data of the corresponding animal's voice is extracted from the audio data memory 2.

On the other hand, the data AD read from the music data memory 1
When /MKC is the key code MKC, that is, address <t+1>, <t-+-3>, <t+4>, <t+5>
If you extract the data, it will look like this:

To explain this using an example where data at address t+4 is read out, the data AD read out from music data memory 1, "MKC", that is, the first key code MK.
C is sequentially connected to the conversion memory 27-\ through the switching devices 23 and 25.
Supplied. The conversion memory 27 stores the input key code M.
When the above-mentioned key code MKC is supplied to the ROM which converts KC into address data AB pointing to the first address of the corresponding audio data storage section in the audio data memory 2', the address ( Address data AD' pointing to Lr) is output. Address data AD' pointing to this address (Lr) is supplied to an adder circuit 9' and an audio data 5 computation circuit 1σ. On the other hand, the signal NEXT used to read the data at address <t+4> of the music data memory 1 is transmitted to the OR gate 12. Delay circuit 13. Switch 24. The signals are sequentially supplied to the audio data reading circuit 10' via the AND gate 28. As a result, the audio data reading circuit 10' is activated and the audio data memory 2
'1-2 voice data can also be read out. This digitized audio data is supplied to the D/A converter 14 via the OR circuit 26, and as a result, the original audio data is reproduced.

However, according to this configuration, if the selection switch 22 is turned on, the music stored in the music data memory 1 can be played back using the sounds of the animals and the voices of the scale names.

In each of the embodiments described above, the song data memory 1 has been explained as a ROM in which song data is stored in advance, but the song data memory 1 is configured with a random access memory (RAM), and this RAM has a magnetic memory. Music data may be input from a storage medium such as a tape, or by operating a program switch, a keyboard, or the like. Further, in each of the above embodiments, the voice data memo +) 2 in which voice data is stored,
2' was used, but as a method for generating sound, an audio data memory in which audio signal formation parameters are stored is provided, and these parameters 7c are used.
It is also possible to use a digital 71' router, etc., to control the entire system, thereby generating phonetics.

As is clear from the above description, the automatic performance device according to the present invention includes a music data memory, an output control means for sequentially reading out data related to the performance of music from the music data memory, and an audio data memory. Since an audible signal generating means having an audible signal generating means is provided and the animal sounds are reproduced using the data of the audio data memory in part or all of the music reproduction process, the animal sounds etc. are included in a part of the music. It is now possible to play songs that have been inserted,
This makes it extremely useful for music lessons for children.
