DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment shown in the drawings will be described below in detail. In this embodiment, an electronic musical instrument and a personal computer are combined to constitute a performance system. In the figure, reference numeral 1 denotes a personal computer, and a personal computer 1 for inputting a plurality of commands and data. A keyboard 2 having a plurality of keys is provided. On the right side of the keyboard 2, there is a cursor movement key unit 2-1 formed of a touch switch (details will be described later).

The operation is performed according to information input from the keyboard 2 or information input from an external storage medium, for example, a floppy disk, a magnetic recording cassette tape, a ROM / RAM package, etc. (none of them are shown). The personal computer 1 includes a central processing unit 3 having an arithmetic circuit for executing processing, a memory circuit, and the like therein, and a CRT 4 for displaying the above-mentioned input or operation result or graphic display.

Data is transferred from a signal input / output port on the back of the personal computer 1 to an electronic musical instrument 6 via a cable 5. That is, the personal computer 1 generates performance information for automatic performance, and transfers the generated performance information so that a tone corresponding to the performance information can be generated inside the electronic musical instrument 6.

The electronic musical instrument 6 has a keyboard 7 that can be played along with an automatic performance according to performance information transferred from the personal computer 1. Of course, this keyboard 7
Can be used irrespective of automatic performance to perform manual performance. In the figure, reference numeral 8 denotes a switch for setting a tone color, rhythm, and the like, and reference numeral 9 denotes a speaker.

Next, the circuit configuration of the performance system shown in FIG. 1 will be described with reference to FIG.

The operation signal of the keyboard 2 is sent to a control circuit 31 in the central processing unit 3 and processed as appropriate.
The switch 21 of the cursor movement key section 2-1 is set to CR
The switch 22 is for moving the cursor displayed at T4 upward, the switch 22 is for moving the cursor rightward, the switch 23 is for moving the cursor downward, and the switch 24 is for moving the cursor downward. Moves the cursor to the left. The designation switch 25 is for instructing input of information currently surrounded by the cursor to a predetermined register. The control circuit 31 also detects the operation of the cursor movement key unit 2-1.

The control circuit 31 makes various decisions while using a control register 32 including registers AC0, AC1, ADR1, ADR2, and ADRM, which will be described later, and stores final information in a memory 33. In addition,
The memory 33 can be divided into a plurality of areas. The control circuit 31 can specify the address of each area, and can write and read data to and from the memory 33.

The control circuit 31 sends and receives data and control signals to and from the mixdown section 34, thereby performing a mixdown function. That is, for example, after input of performance information for each bar is performed for each part and stored in a plurality of memory areas in the memory 33, the mixdown section reads out the information and reads the timing information ( By adjusting the length information, the function of inputting the performance information of one bar mixed down into one memory area is achieved.

A display driver 35 generates data to be displayed on the CRT 4 and drives the display.

The personal computer 1 having such a configuration is connected to the interface circuit 61 of the electronic musical instrument 6 via the data bus 5-1 in the cable 5. The interface circuit 61 controls the control circuit 6 in the electronic musical instrument 6.
2 for controlling the exchange of data with the electronic musical instrument 6. The control circuit 62 is further supplied with a signal from a keyboard 63. The keyboard 63 corresponds to the keyboard 7 and the switch 8 in FIG.

Accordingly, the control circuit 62 stores the performance information input from the keyboard 63 in the memory 64 and prepares for automatic performance, or supplies the performance information to the tone generation circuit 65 to generate a tone. Further, the control circuit 62 stores the performance information transferred from the personal computer 1 in the memory 64, and then sequentially sends the information indicating the scale or rest to the tone generation circuit 65 according to the timing information. To perform an automatic performance. The tone signal output from the tone generation circuit 65 is converted into an acoustic signal by the speaker 9 and is emitted.

Next, a method for inputting performance information according to the present embodiment will be described below. FIG. 3 shows a CRT when a mode for inputting performance information is set by operating the keyboard 2.
4 is a diagram showing a display state of the CRT 4 under control of the control circuit 31. In the CRT 4, a mark 401 such as a musical note, a rest, etc.
02 are displayed. Also, a cursor 403 is displayed. And a line 4 for distinguishing the upper and lower rows.
04 is shown.

Each of the cursors 403 has a size corresponding to that of the mark 402, and is operated by operating each of the switches 21 to 24 of the cursor movement key section 2-1.
It can be moved right, down, left.

FIG. 4 is a flow chart showing the processing operation of the control circuit 31 in response to the operation of the cursor movement key section 2-1. First, in step S1, it is judged whether or not the designation switch 25 is turned on. When the determination is made, the process proceeds to step S2, and it is determined whether any of the cursor movement switches 21 to 24 is operated. If the determination is NO, the process returns to step S1. Now, for example, when the switch 24 is operated, the process proceeds to step S3.
03 to the left.
The cursor 403 on RT4 moves to the left.

Thus, the cursor 403 is moved to the switch 2
By operating 1 to 24, the robot moves to the position shown in FIG. When the designation switch 25 is operated in the state of FIG. 5A, YES is determined in the step S1.
Is determined, and the process proceeds to step S4. In step S4, it is judged whether or not the cursor 403 is above the line 404. Since the cursor is now below the line 404, a determination of NO is made, and the process proceeds to step S5. In step S5, the sound length information (or a special symbol or the like) is written in the register ACO in the control register 32 by judging from the current position of the cursor 403. In this case, the note length information is a code indicating a half note.

Then, following step S5, the process proceeds to step S1, where it is judged whether or not the designation switch 25 is pressed. If NO is determined, the process proceeds to step S2. Now, if the cursor 403 is moved upward by operating the switch 21, the processing in step S3 becomes as shown in FIG. 5B. When the designation switch 25 is operated in this state, steps S1, S4,
By the processing in S5, the content of the register ACO is partially corrected, and a code indicating information of a half note and ♯ is input. The display in the cursor 403 changes as shown in FIG.

Next, switch 21 and switch 2
The cursor 403 is moved to the position shown in FIG. At this time, the display in the cursor 403 remains as shown in FIG. When the designation switch 25 is operated in the state shown in FIG. 5C, the process proceeds to step S6 following steps S1 and S4, and corresponds to the current cursor position, that is, the position of the half note ball in this case. The pitch information to be generated is generated by the control circuit 31 and input to the register AC1 in the control register 32.

Then, in step S7, the memory 3
The pitch information of the note concerned is stored at the first address of the third predetermined area, and the timing information (length information) is stored at the next address. The specific data storage state will be described later. Then, the display inside the cursor 403 in FIG. 5C is fixed on the five lines 401, so that the subsequent movement of the cursor 403 does not include the display inside.

In step S8, a judgment is made as to whether or not the total length information of the performance contents in the predetermined area of the memory 33 exceeds the length of one bar. Since the length of the whole note (represented by CO as will be described later) is one bar long, this song is compared with the length of this whole note.
Is determined, the process returns to step S1. If it is determined in step S8 that "equals", the input of the performance information of one measure is completed, and the process shifts to the input of the next measure. If it is determined in step S8 that the sound is "large", it means that the performance information has been input beyond the length of one measure, and an error is displayed on the screen of the CRT 4 in step S9. .

By inputting the performance information for each note in this manner, the performance information for one measure is stored in the memory 3.
3, and by operating it again, performance information of one tune is input.

Now, in this embodiment, as shown in FIGS. 6A and 6B, the codes indicating the scale and octave are sounding (KEY ON) and silencing (KEY OF).
It changes depending on the information indicating F). Then, the timing information specified by the sound length or the rest length is coded as shown in FIG. Now, the code in FIG. 7 is represented in hexadecimal.

Therefore, for example, if performance information is inputted as shown in FIG. 8B following the note shown in FIG. ) Is stored.

That is, in the data shown in FIG. 8E, the first byte “c3” is the third octave c♯.
To start generating the scale sound of. The next one byte “60” indicates the length of a half note. The next byte "c
B "instructs the start of silencing of the scale tone that has started sounding.
The next byte "00" indicates that the duration of the note is zero, and the scale note specified by the next byte is processed at the same time as the silence of the scale note c #. The next scale note is the scale note B of the second octave. Further, the next byte "30" indicates the length of a quarter note. The next byte "BA" instructs the silence of the above-mentioned scale sound B. Since the next byte is "00", the sound of the second octave scale tone A indicated by the next byte is generated simultaneously with the silence. Instruct to start. Then, in the next byte, it is understood that the note length corresponds to a quarter note. Next byte "AA"
Indicates that the above-mentioned scale sound A is to be silenced, and that the next byte "00" indicates that the generation of the scale sounds of all measures is completed.

Thus, the performance information of one bar shown in FIG. 8B is coded and stored in the memory 33.
Then, in the same manner, by sequentially inputting the performance information of the following measures, the performance information of the entire music piece is stored in the memory 33. Thereafter, the performance information is transferred to the electronic musical instrument 6 by a predetermined operation of the keyboard 2 and stored in the memory 64. Therefore, in the electronic musical instrument 6, the performance can be executed by sequentially providing the musical tone generation circuit 65 with the performance information read from the memory 64.

In the above embodiment, the present invention is applied to a performance device in which an electronic musical instrument is combined with an electronic computer such as a personal computer. However, a display device, for example, a liquid crystal dot matrix display device is provided in the electronic musical instrument. With
A similar display can be performed to input performance information.

When a tone generator is provided in an electronic computer such as a personal computer, the present invention can be implemented by itself.

In the above embodiment, the cursor is a quadrangle. However, the cursor is not limited to this, and may be, for example, a simple line (underline).

In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.
