【Example】

 An embodiment of the present invention will be described below with reference to the drawings. <Structure> FIG. 1 shows the overall circuit structure of this embodiment, and FIG. 2 shows its external appearance. Reference numeral 1 denotes a switch unit including each control switch, the operation of which is discriminated by the CPU 2 and a corresponding process is performed. As shown in FIG. 2, in the upper part of the electronic musical instrument, each of the above-mentioned control switches such as power-off, song number selection display, navigation, normal play, automatic performance / position display, and manual performance of selected song A mode switch 1a for selecting a mode, a start / stop switch 1b for automatic performance, a rhythm selection switch 1c for selecting a rhythm stored in the rhythm pattern memory 3, a tone selection switch 1d for selecting a tone color, and a volume control A volume switch 1e to be controlled and a program switch 1f for selecting the number of songs are provided.

The keyboard 4 is located in front of the electronic musical instrument, and each light emitting diode 5x forming the LED display section 5 is provided above each key of the keyboard 4. As will be described later, in this embodiment, each light emitting diode 5x of the LED display section 5 is used not only as a navigator for performance practice but also for displaying the progress status of the performance.

Reference numeral 6 denotes an automatic performance memory for storing automatic performance information, and here, as shown in FIG. 2, it is composed of a ROM pack which is mounted on the electronic musical instrument at any time. When the selected song in the ROM pack 6 is automatically played, the CPU 2 reads the automatic performance information, and the musical tone information of the melody tone and the chord tone of this automatic performance information is given to the musical tone generating circuit 7. Then, a musical tone signal is generated, and the rhythm information is given to the rhythm sound generating circuit 8 to become a rhythm sound signal, both of which are emitted through the amplifier 10 and the speaker 11.

The CPU 2 is provided with a register unit 2a. As will be described later, the DR register is used as a display register for displaying the song number position and the performance position on the LED display unit 5, and the UL register is used as a unit time. Used as a long timer or counter.

<Operation> Next, the operation of the embodiment will be described. The normal play mode in which the mode switch 1a is set to the normal play position A is the same as that of a normal electronic musical instrument, and therefore its explanation is omitted, and the navigation mode, the number of songs selection display mode, the automatic performance / position display mode are used. The manual performance mode of the selected song will be described.

Navigation Mode When navigating a selected music piece of the ROM pack 6, the mode switch 1a is set to the navigation position B. When the start / stop switch 1b is used to instruct the start, the CPU 2 reads the performance information of the selected song from the ROM pack 6, decodes the pitch information thereof, and converts it into information for controlling the LED display section 5, which corresponds to it. The light emitting diode 5x is turned on. For example, when the pitch information corresponding to E ₃ (mi) is received from the ROM pack 6, the light emitting diode 5x above the E ₃ key (FIG. 2) is turned on. On the other hand, when the performer presses the E ₃ key, the performance information currently stored in the internal register of the CPU 2, in this case, the performance information including the pitch information of E ₃ is sent to the tone generation circuit 7. The sound is emitted through the sound system 10, 11. Subsequently, the CPU 2 starts reading the next performance information from the ROM pack 6, and thereafter repeats the above operation.

Music number selection display mode (FIG. 3) When it is desired to automatically perform a plurality of music pieces in the ROM pack 6, the mode switch 1a is set to the music number selection display position C. Then, as shown in step S1 of FIG. 3, the designation of the number of pieces of music is input through the program switch 1f. Thereby, the music number counter in the CPU 2 is set to the designated value (step S2). Then, "1" is set in the display register DR according to the content of the music number counter, and the corresponding light emitting diode 5x is turned on (steps S3 and S4).

For example, when 6 songs are designated, in FIG. 2, six light emitting diodes 5x are turned on from the left end. Then, when the start / stop switch 1b is instructed to start the automatic performance (step S5), the CPU 2 sequentially reads out the performance information of the selected music from the ROM pack 2 to generate the musical sound generating circuit 7 and the rhythm sound generating circuit. Then, the operation is repeated, and the address is advanced to read the next performance information. When the end address of the selected song is reached, the automatic performance for one song is completed (step S6), the song number counter is decremented by 1 (step S7), and the above step S3 is performed until the number of the song number counter becomes zero. Repeat the following process.

Therefore, the number of remaining songs is displayed on the LED display unit 5, and the user can immediately confirm the number of remaining songs automatically played from the number of the light emitting diodes 5x that are lit. When the automatic performance of the designated number of songs is completed, the content of the song number counter becomes zero (step S8), all the display registers DR are set to "0", and all the light emitting diodes 5x of the LED display section 5 are turned off ( Steps S9 and S10). As described above, in the number-of-tunes selection display mode, the progress status of the automatic performance of a plurality of songs can be known through the LED display unit 5.

Automatic Performance / Position Display Mode (FIG. 4) In this mode, one song selected from the ROM pack 6 is automatically played , and the current playing position is displayed via the LED display section 5. It In this example, since the LED display section 5 is composed of 32 light emitting diodes 5x, the total sound length of the selected song is divided into 32, and all the light emitting diodes 5x are turned on at first, and the unit time length, that is, The process of turning off the lights one by one every time 1/32 of the total sound length has elapsed.

More specifically, when the mode switch 1a is set to the automatic performance / position display position E and the start / stop switch 1b is used to instruct the start, the flow of FIG. 4 starts. First, the unit time length is calculated from the total tone length of the selected song in the ROM pack, the ROM address is initialized to the start position of the selected song, the basic clock generation timer is set, and the display register DR is set to all 1 ( Steps T1, T2, T3, T4).

Subsequently, the number of light emitting diodes 5x according to the contents of the display register DR is turned on, the performance information of the current address is read from the ROM pack 6, and the musical tone generating circuit 7 and the rhythm are reproduced according to the pitch information. The sound generation circuit 8 (TG) is sounded (steps T5, T6, T7). Subsequently, for the tone length processing, the tone length data is decremented by 1 each time the basic clock timer times out, and the tone length data is repeated until it becomes 0 (steps T8, T9, T10).

When the tone length processing is completed, the read address of the ROM pack 6 is advanced (step T11), and if it is not the end address, it is determined whether or not the unit time length timer UL has timed out (steps T12 and T13), and the time out is performed. If not, the process directly returns to the step T5, and if the time-out has occurred, the next 1 bit of the display register D R is set to zero in step T14 and then the process returns to step T5. The steps T5 to T12 correspond to a normal automatic performance process without displaying the performance position.

Manual Play / Position Display Mode of Selected Song (FIG. 5) In this mode, a manual performance of the selected song from the ROM pack 6 is carried out for practice, and at this time, the LED display section 5 indicates to what extent the performance has been executed. Displayed by. In order to show the progress of the performance in one song, the processing which is quite common with the automatic performance / position display mode of FIG. 4 is performed. However, in advancing the execution steps, in this example, the condition is that there is a key depression that matches the performance information of the ROM pack 6, especially the pitch information. That is, when there is a key input that matches the pitch information of the ROM pack 6, the corresponding tone processing is performed and then the read address for the ROM pack 6 is advanced by one and the unit time length timer used in the mode of FIG. The contents of the corresponding unit note number counter are updated. Then, each time the unit note number counter overflows, the light emitting diodes 5x are turned off one by one.

More specifically, to enter this mode, the mode switch 1a is set to the corresponding position F 1. As a result, as shown in FIG. 5, the unit note length (= total note length / 32) is calculated from the total note length of the selected song in the ROM pack 6, the ROM address and the unit note length counter are initialized, and the display register DR is cleared. Set to 1 (steps U1, U2, U3). Then, the light emitting diodes 5x are turned on according to the current contents of the display register DR (at first, all are turned on) (step U4), and a key press is waited. If there is a key press, the pitch related to the key press and the ROM pack It is determined whether or not the pitch information of the current address of No. 6 matches (steps U5 and U6).

When there is a coincident key depression, the unit note number counter UL is incremented by +1 and the tone reading circuits 7 and 8 are subjected to sound generation processing by the information read from the ROM pack 6 to obtain the ROM pack. The read address of 6 is advanced by one (steps U7, U8, U9). If the end address has not been reached, it is judged whether or not the content of the counter UL has exceeded the number of unit notes (steps U10 and U11). If not, the process returns to the above step U4 without doing anything. If it exceeds, the next one bit of the display register DR is set to zero in steps U12 and U13, the counter is reset, and then the processing returns to step U4 and the subsequent steps. As a result, the light emitting diodes 5x are turned off one by one each time a correct key depression corresponding to 1/32 of the total note length of the selected song is performed, and the performer can easily confirm how far he or she has practiced.

[Modification]

 The present invention is not limited to the above embodiment, and various modifications and changes can be made. For example, in the above-described embodiment, in order to show the progress of the performance, all the light emitting diodes are first turned on, and then turned off sequentially in accordance with the progress. All the lights may be turned off and then sequentially turned on in accordance with the progress, or only one light emitting diode may be turned on at a time and the lighting positions may be shifted one by one in accordance with the progress.

Further, blinking (blinking) may be performed in addition to lighting or extinguishing. For example, the number of the song currently playing is indicated by a light, while the number of songs is indicated by a blink, or the song currently being played is indicated by a blink, and the next song is played. It is possible to display the song by lighting it, and so on. Alternatively, the navigating light emitting diode may be turned on, and the currently selected song (or the current progress position in the song) may be processed by blinking. In this case, the selected song and the current position in the song can be known at the same time as navigating. Further, the display section is not limited to the light emitting diode, and other display elements (EL, plasma, etc.) may be used.
