The operation panel section 2 has controls for setting rhythm, tone color, volume, effects and the like, and controls such as a demo switch for instructing automatic performance based on preset automatic performance data. Is arranged.

The CPU 3 performs a scan process of each key switch of the keyboard 1 and a scan process of each operator of the operation panel unit 2 in accordance with a program stored in the ROM 4, and performs an operation state of each key of the keyboard unit 1. (Depression of a key, release of a key, key number of an operated key, velocity related to the operation speed of the key, etc.) and the operation state of each operation element of the operation panel unit 2 are detected, and the operation state of each key or the operation element will be described later. Execute each process.

The ROM 4 stores a work program of the CPU 3, tone waveform data, and n types of font data used when displaying a human having various forms, which will be described later, on the display unit 20 including the LCD of the display 7. At the same time, several types of automatic performance data used when performing the automatic performance are stored as preset data. As shown in FIG. 2, the automatic performance data includes a tone number for specifying the type of tone, a key number for specifying the type of key, a step time indicating the timing of sound generation, a gate time indicating the time of sound generation, Key speed (size of pronunciation)
And a repeat mark indicating a repeat point.

The ROM 4 also stores a plurality of types of display sequences corresponding to the respective types of the automatic performance data. This display sequence determines the display order of various human appearances to be displayed on the display unit 20 of the display unit 7 when the selected automatic performance data is reproduced. As shown in FIG. (Addresses of the RAM 21 described later) are stored in the display order.

The RAM 5 has a storage area for temporarily storing various kinds of information in the course of execution of various kinds of processing by the CPU 3 and for storing information obtained as a result of various kinds of processing, and a buffer as shown in FIG. It has LCDDBUF. Each storage area of the buffer LCDDBUF is made to correspond to each of the 16 divided display areas of the display unit 20 of the display 7.

The tone generating circuit 6 has a plurality of tone generating channels and is configured to be able to generate a plurality of tone simultaneously. The tone generating circuit 6 forms tone data in a digital data format based on key number information indicating each key sent from the CPU 3, tone parameter information set by operating each operation element, and the like. Note that the tone generator 6 also includes a digital filter, a digital effect adding circuit, and the like.

The tone data generated by the tone generating circuit 6 is converted by a D / A converter 8 into an analog tone signal. The tone signal is amplified by the amplifier 9 and applied to the speaker 10.

The display 7 is provided with a display section 20 comprising an LCD, and the display section 20 is divided into 16 display areas (0 to 15) as shown in FIG. In the case of the present embodiment, the display area of the display unit 20 is such that 0 to 6 are the song titles, 7 to
9 is assigned to the melody 1, 10 is assigned to the melody 2, 11 to 13 is assigned to the chord, 14 is assigned to the display for the bass, and 15 is assigned to the display for the drum. This assignment is appropriately changed according to the type of the automatic performance data. Is done. In the display areas for each of the tone sequences 7 to 15, a display representing a person having various forms is displayed. The basic posture of the person displayed in the display area for the melody lines 7 to 10 is that the right leg is open toward the human, and the person displayed in the display area for the code parts 11 to 13 is facing the person. The basic posture is that the left leg is open and the basic posture is that the human being displayed in the display area 14 for the base part is the basic posture where both feet are aligned. The displayed human is in a basic posture with both legs spread. By changing the basic posture of the human being displayed for each part in this way, it is possible to know at a glance which part is being displayed.

In addition, the display of each person is performed such as raising and lowering the arms as the music progresses in the basic posture. Also, the display of the sitting state of the human being displayed in the display areas 11 to 13 and 10, 14 and 15 in FIG. 11A is a rest in which the performance of the part is not currently performed. It indicates that it is in the state. In the case of a rest, the display in which a human is seated is performed because the display of a non-operating human is visually disturbed while the display of another human is operating. By setting the display to be a short sitting display, the movement of the human display during operation is further emphasized. The melody line 2, the bass part, and the drum part each have one human display, and the melody line 1 and the chord part each have three human displays. This is because the performance of the melody line 1 and the chord part has a lot of tone information (there is a lot of sounds), while the single tone performance is many.

In the display of the three humans on the melody line 1, the movement is controlled in order each time the tone information (key number) of the melody line 1 is detected.
The display of the three humans of the chord part is such that when the musical tone information of the chord part is detected, the movement of the three humans is simultaneously controlled regardless of the number of sounds. This means that the chords that make up the chord part are three tones,
This is to prevent the display operation of each person from being varied according to the number of sounds because the sound is a sound or two sounds.

As shown in FIG. 5, the display 7 also has a RAM 21 in which eight kinds of font data read from the ROM 4 when the electronic musical instrument is used are set in storage areas of addresses 0 to 7, respectively. Is provided.

The data is stored in the storage area of the corresponding address of the DBUF. Then, in step S9, the address of the buffer LCDDBUF is advanced by one. By the processing of these steps S6 to S9, each time the pronunciation information (key number information) belonging to the melody line 1 is detected, the display of the three humans associated with the melody line 1 sequentially raises and lowers the hand. It is operated as follows. The contents and procedure of this operation are determined by the display sequence (see FIG. 3).

On the other hand, when it is detected in steps S2 to S5 that the melody line 2, the chord part, the bass part, and the drum part are produced, the display sequence shown in FIG. 3 is advanced by one (steps S10 and S12). ,
14 and 16), a predetermined font No. is stored in the storage area of the corresponding address of the buffer LCDDBUF according to the sequence. Is written (steps S11, S13, S15,
17). At this time, the font No. Is written to the storage areas of the buffers respectively corresponding to the display areas assigned to the respective parts on the display unit 20 of the display unit 7. In the case of a code part, the display of the code part is performed. The same font No. is stored in the three storage areas of the buffer LCDDBUF corresponding to the three display areas (11 to 13) allocated for the same. Are written at the same time. Therefore, in the case of the code part, the display of three persons always performs the same operation.

In this display control process, after performing the above process, the rest checking process shown in FIG. 10 is executed in step S18, and then the process returns to the main flow of FIG.
