Description

[Detailed description of the invention] The present invention relates to an electronic musical instrument having a memory editing function.

In recent years, electronic musical instruments have been put into practical use that read out continuous musical tone information, ie, song information, from memory and perform automatic performance. In the conventional electronic musical instrument of this type, musical tone information is written into the forehead from the first address of the memory. 1. [As above/
In the case of yo(i), even if the song has a lot of repetition, the song 1n suho must be manually created in order to repeat the repetition.For this reason, manual operation is difficult.
Not only does this result in an iL problem, but it also causes problems such as not being able to effectively use each portion of the limited memory.

This 1st part 1 was made from Koni IC's small 1η to 9 thick t, and the 1 part 1 process 1 is to divide the memory into multiple W+J t, and store the music ff in each divided memory.
By inputting 4 pieces of information and specifying the ``-'' memory readout 1lI (intro) program, it is possible to automatically play long songs with many repetitions even with a small memory capacity, and it also saves the user's input time. It is an object of the present invention to provide an electronic musical instrument having a memory collection function that minimizes the amount of memory.

Hereinafter, an embodiment of the present invention Mli will be described in detail with reference to drawing '1i.

The scale display section 7b displays chord positions.

Next, the operation of the above embodiment will be explained. First, let's start with the song [θ1' 4th child's good luck JIJ (composed by Handel), which is not shown in Figure 4.
The explanation will start from the 403rd work to be preset in the performance memory 18.

Introduction Mode selector switch 8 All recording mode position (R
EO). Next, after operating the memory key 4a, select any one of the eight memories M1 to M8 in the performance memory 18 using the eight leftmost black keys. For example, select memory M1. do.

As can be seen from Figure 4, in the song of the example, the score from the first bar to the third bar % J1 beat [] of the second stage is one middle and 7, and the next third bar tJJJ2 5th from beat
This is repeated until the next measure. When you have finished inputting up to the 3rd minor f6j l beat of the row, press the old memory key 4a and then press one of the eight black keys on the left. Then, operate the key labeled λi2 to specify memory M2. After this, the bottom 5 of the sheet music
By inputting the measures, the minimum amount of information necessary for automatically playing the song is completed manually.

Next, please refer to Figures 5 to 8 for the manual method of music information used in this embodiment. I, I without explaining in detail 2)
. As mentioned above, in the recording mode, if memory M1 is not specified (a), data 1M1 is stored at the first address of the area of memory M1.
" is written. More than that! In the flowchart of FIG. 5, the process of steps S11 and S2 causes the memory M1 to be selected, so the display f71'
At +7 (: tε4゛This ll:fNme);su), +l is addressed by the IJ address counter 19.

Next, operate clear key 4n to clear the contents of memory M1, and then input music regardless of the note length. In this example, the melody data is represented by 4 digits (1 digit - 4 bits) and the code data is represented by 6 digits, and these melody and code data are serially recorded in the memory. It looks like this.

First, in order to input the first food data "yJ" manually, among the code designation keys 1j#3, the key displayed as ffJ is operated, and 0PU13 is first input by the process of step s3 in the flowchart of FIG. Ta'
It stores the IVI information in itself, then performs the process of step S4 to judge whether the information is a code or not, and then writes the code into the memory M in step ss.
'JVj6 digit IB+ is executed to determine whether or not there is a free space, and since there is naturally enough space in M, to insert the code, the code data "FJ)I" is stored in the memory M1.
-II input step S6 ν4! , and execute steps S and J. Next, in order to input the first melody data [Fa], one of the transformation keys 1 and 2, approximately in the center, ``7'T'' key is created. For the entire time, n + months "1 interval 4; f + step ss or la step S)" will proceed, but as the melody data is input here, step S,
7) c7. ) Check whether there is a vacancy or not. In this case as well, there is naturally J vacant space, so step s6
The processing of ``A'' is performed, and the ri'J chord data ``F'' is entered, and later the melody data ``F'' is entered 1).If you operate the ``U'' key next, you will follow exactly the same steps. The melody data “U” is written immediately after the melody data “F”, and in the same way, the melody data “C”
” “N” “Do J rFJ r u” “N” “
"F""0""N""Do"...
Musical tone information is written as shown below.

Therefore, the first note of the third minor fij, that is...
0" and "C", as described above, after operating the old memory key 4a, operating the key indicated as M2 to specify memory M2, and then easily inputting the 5th small in the lower row of 19. Enter Setsubun. Also, in step S6 or step S9, the memory unit in memory M1 must be
(When it is determined that there is no space for digits, the process advances to step S7, determines whether there is space in the next memory unit, automatically writes that information to the next memory unit, and returns to step S3. Furthermore, if there is no free space in the next memory unit in step S7, step Sh.

The display unit 7 lights up the display ``M-ov]lCuJ to indicate that the memory is over.

In addition, the human power f? 1 signal is also given to the melody generation circuit 15 or the hood generation circuit 16 at the time of its input to create the melody tone or chord tone, and then output to the speaker 1.
7. Sound emission tn port 0 fL, sound is emitted.

Next, a program operation is performed to automatically perform each part of the music piece recorded in each memory unit as one piece of music. First operate the EDIT key (EDIT) 4k, then use the black keys mentioned above to press Mlr Mlr Mlr
When you operate the keys in the order of ``Ml'', the program memory area in the memory 18 will have ``Ml'', ``Ml'', ``Ml'' in that order.
” 1# report “Ml” is written. At this time,
The address specification for this program memory area is 0PU1
This is done by the program memory address counter 16A in 6. By specifying the order as described above,
It becomes possible to perform an automatic performance according to a certain rJ shown in FIG.

Using the drum, explain the number of digits required to record the chords and melodies mentioned above and the recording format. For melodies and hoods recorded in the performance memory 18, 8 bits represent the note length, the next 4 bits represent the scale, and the next 2 bits represent the ratio of the key-on time to the key-off time, that is, an approximation of the note length. The melody flag is used to distinguish between the melody and the chord using the 1 bit after the chord, and a total of 16 bits, or 4 digits. is expressed using. On the other hand, a chord is represented by 6 digits (24 bits), and the first 4 bits represent the type of chord such as minor or seventh, the next 11 bits represent the note length, and the next 1 bit and the last 1 bit represent the chord. Set the hood flag to the next 4 bits to set the root m of the hood, and set the 3rd bit before the 1f bit to the hood flag.
The above-mentioned S/R is expressed in bits. The reason why there are two hoods 7 is so that when reading the contents of the performance memory 1B, the flag will be at the same position regardless of whether it is read from the first address side or the last address side. This is provided to prevent malfunction.

FIG. 6 schematically shows the final recording state of the performance memory 18 into which the song has been written by the above operations, and the chord data and melody data are of a length of 3=2 according to the format described above. It is expressed as. That is, as shown in Figure 4, the first and second measures of the song:
Since the first beat of the third measure, the second beat of the third measure, the fourth measure, and the first beat of the fifth measure are the same content, the fIt information is recorded in the memory M1. Also 6=10
Although the small M'jth part is repeated twice, the information in this part is recorded across two memory areas.

And the program memory contains data as shown in the figure.
+ ' 1 * M 2 r Ml is written, and the edited contents of the memory are recorded. In addition, 6 to 10 lh
The f61 UI portion is recorded across two memory areas as described above, and is written as Ml in the program memory, indicating that it is a series of ffJ information.

Figure 7 shows how to write the musical scale in the schematic diagram of Figure 6. is "↑゛" ~ "shij
This indicates that it has been entered.

The tel in FIG. 8 shows the display state of the display ff1s 7 when the news is being recorded in the memo 'J IA 2, and the tel in FIG. It also shows that a series of 1)'J reports are being recorded.

After inputting the chord and melody using the steps above, use Morte to add note length to the notes.

The selector switch 8 is in the recording mode (REO) (set aside), and the reset key 41 is operated to find the beginning of the song.

For example, if you play the one-key play key 6a according to the actual note length while playing the rhythm of a march, each melody will be played while the operation time is changed to n1 by the melody note length counter 15E.

At the same time, the performance memory 1 is read out and played.
One key brake on the note length part of each melody within 8.
The note length as played is added by 6 &, and the total note length of each melody group in that melody group is written as the chord note length in the chord data located in the order preceding each melody 8'1'-. .

181 The oPU 15 sets the melody tone length counter 16B in the one-key operation IU of the French melody, adds each melody tone length to the food naginata counter 16a, and when reading the next food, =I-1° Long counter 1?6o
At the same time, the code length data is input 19 times as the hood length data of the hood.

Chapter 1.01<l explains how to edit ``1 Grano and Zomori'' for other songs with more complicated repetitions.
[>] (1i~(A) is a song divided into groups of measures of number of steps, PI, and shown symbolically using the symbols A and -1F. In this song, D, O, and D are divided into groups of measures. There is a repetition symbol I+: :I+ between the parts, and a repetition symbol Z (Seni W) is between B and 0, and at the end of O and the beginning of F there is a repetition symbol (There is one mark.

Therefore, the performance of this song is A, B, O, D.

Must be done in the order B, O, E, O, F. As shown in FIG. 10 CB), in the performance memory 8, for example, parts A to F of the song are stored in memories M1 to 'M6, respectively. Then, as shown in Figure 10 (0), the data is stored in the program memory according to the order in which the songs are played.
I p M2 e M3 r M4 e M2pM 3
．． Write M 5 e' M 3 and M 6. In this way, by referring to the data in the program memory for each shift, the automatic performance of the song shown in Figure 10 (A) can be performed by a DJ, and even songs with complicated repetitions can be easily performed automatically by sequential programming. You can go.

FIG. 11 is an example in which memory compression is performed to further improve memory usage efficiency. That is, in FIG. 6, a portion of the memory M1 is unused, but in FIG. 11, the unused area is also included in the memory M2. This is a set of information stored in the M5, and in this case, an end mark (e21d) is stored at the end of each block of the telephone information using a predetermined key or V operation. In addition, the program memory contains the ↑a report block first [4 address is the direct address adλ(1, adM2 as shown in the figure) in the performance memory 18, a d !, i1, a d

Editing and recording are performed in the order of 2. If you make it like a mouth, it's me% 'J
17J Since there are no blank spaces in the middle), the maximum memory can be used efficiently, which has a great effect.

In addition, in the example of Kinomi 1j111, pear song f'i is stored in the memory.
Various key human-powered devices were used as a means of manually inputting the 7 reports, but without being affected by these, barcode readers, 1-feelings, optical reading devices that directly read certain messages, voice input, etc. Various other hexagonal means may also be used.

Furthermore, in this embodiment, the code 17f report was inserted and written between consecutive ff floor t/1 reports, but the invention is not limited to this, and a plurality of memories may be provided to store the melody and chord separately. It may also be possible to read out the data in synchronization with each other.

Further, although this embodiment has been shown to be applied to a small portable electronic musical instrument, it may also be incorporated into a large one-ring type electronic keyboard instrument or other digital synthesizers, and may also be applied to a small programmable electronic keyboard instrument. Or as part of the function of a small device such as a personal combination heater.
It is also possible for the i7J to be provided as a C1 or as a standalone device.

As explained above, the invention of the invention is that when recording musical tone t# information of automatic performance ≦nodame in memory, the storage area of the memory is divided into a plurality of areas and the music information is recorded from any area. Since we provided an electronic musical instrument with a memory editing function (stored in memory), we were able to provide an unprecedented 11L child instrument, and especially in the case of a song with a lot of repetitive parts, the ability to edit the memory allows you to repeat it repeatedly. It is good to record the partial number in memory only once, so it has the advantage of increasing memory usage efficiency.
