【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the electrical construction of an automatic musical instrument according to an embodiment of this idea, and FIG. 2 is a perspective view showing the external construction of the embodiment. In FIG. 1 and FIG. 2, reference numeral 1 denotes a keyboard composed of a large number of keys, and the key depression and key release of the keyboard 1 are detected by the keyboard circuit 2 shown in FIG. In this case, the keyboard circuit 2 scans each key on the keyboard 1 to detect the pressed key, and outputs the key code KC corresponding to the pressed key in a time division manner.

The writing control circuit 3 constantly or periodically monitors the key code KC supplied from the keyboard circuit 2 to detect a change in key depression state, and the detection result and the rhythm sound control circuit 4 are supplied. The key press time and key release time are determined based on the tempo clock TCLK of a predetermined cycle, and the time data (hereinafter referred to as note length data) and the key code KC are combined into a data memory (performance data). Memory) 5. In this case, the write control circuit 3 increments the count value of the address counter 6 by 1 and increments the write address of the data memory 5 by 1 each time the key code KC is written. The write control circuit 3 is adapted to perform the write operation only when the recording signal REC is supplied, and the address counter 6 is reset when the recording signal REC or the signal PLY is output. It is like this.

The rhythm sound control circuit 4 includes a clock oscillator that generates a tempo clock TCLK, a rhythm pattern generator that generates various rhythm patterns based on the tempo clock TCLK, and various types of output signals from the rhythm pattern generator. It consists of a rhythm tone generator circuit that generates the tone generator signal of the rhythm instrument, and when the playback signal PLY is supplied or the rhythm start switch (not shown) is turned on, the operation starts and will be described later. When the final address detection signal FULL is supplied, the operation is stopped. The rhythm sound signal output from the rhythm sound control circuit 4 is amplified by the amplifier 10 and then supplied to the speaker 11.

Next, when the reproduction signal PLY is supplied, the read control circuit 7 sequentially reads the data in the data memory 5 one address at a time, and uses the read key code data as a key code KC ′ to form a tone forming circuit 9 Supply to. In this case, when reading the key code data, the read control circuit 7 counts the tempo clock TCLK by the number corresponding to the tone length data paired with the read key code data, and at the end of this count. The next key code data is read out. That is, when the read control circuit 7 counts the tempo clock TCLK by the number corresponding to the tone length data, the read control circuit 7 supplies an up pulse to the address counter 6 and increments the read address of the data memory 5 by one.

The musical tone signal forming circuit 9 is a circuit for generating a musical tone signal having a pitch corresponding to the key code KC or the key code KC ′. The musical tone signal output from the musical tone signal forming circuit 9 is the amplifier 10. And then supplied to the speaker 11. The tone color selection display circuit 8 includes tone color selection switches SW _{1 to} SW _n shown in FIG. 2 and light emitting diodes (tone parameter selection state display means) Da _{1 to} Da indicating which tone color is selected. and _n and Db ₁ Db _n, and a display device drive circuits 8b shown in FIG. In this case, the respective switches and the light emitting diodes are provided on the upper panel 19 of the apparatus body as shown in FIG. Although not shown, the upper panel 19 is provided with a memory mode switch 15, an automatic performance mode switch 16, a rhythm selection switch, and other key switches.

Then, the switch SW₁When you press once, the JAZZ ORGAN tone is selected and the emission diode Da₁Lights up and the switch SW₁Press twice to select the PIPE OF GAN tone and light emitting diode Da₁Is lit up. That is, switch SW₁Each time you press, the tones of JAZZ ORGAN and PIPE ORGAN are switched alternately, and the light emitting diode Da₁And Db₁The lights also switch alternately. And other switch SW ₂ ~ SW_nThe function of is also configured in the same way, and only the last operated switch is enabled.

Next, the display driving circuit 8b shown in FIG. 3 will be described. First, the comparator 8d compares the address signal Adr of the address counter 6 with a plurality of internally set reference data, and outputs a "1" signal from any one of the output terminals according to the comparison result. It is like this. Further, reference numerals 20 and 21 denote selectors, respectively. To the input terminals B of these selectors 20 and 21, the tone color selection signal SEL output from the tone signal forming circuit 9 is supplied, and to the input terminals A, respectively. Is supplied with the output signal of the comparator 8d. Then, the selector 20 selects the input end A when the “1” signal is supplied to the terminal SA, and the selector 21 selects the input end B when the “1” signal is supplied to the terminal SB. It is like this.

A signal for instructing lighting of the light emitting diodes Db _{1 to} D b _n of the signal SEL is supplied to each input terminal of the OR gate 22, and as a result, the OR gate 22 is configured to be supplied to the OR gate 22. when any of db ₁ db _n is lit, and outputs a "1" signal. In this case, when the light emitting diode Da ₁ to D a _n or Db ₁ Db _n based on an output signal of the comparator 8d is driven, the address signal Adr large Do Runishitagatte, light emitting diode Da ₁ to DA _n or The lighting of Db _{1 to} Db _n is configured to move from the lower side to the upper side of FIG. 2, for example.

Next, 12 is a final address detection circuit, which detects whether or not the address signal Adr reaches the final address of the data memory 5 and outputs a signal FUL L when the final address is detected. is there. A switch control circuit 14 outputs a recording signal REC when the storage mode switch 15 is turned on and outputs a reproduction signal PLY when the automatic performance mode switch 16 is turned on. The switch control circuit 14 is configured to enable the last one of the memory mode switch 15 and the automatic performance mode switch 16 that is turned on, and when the signal FULL is supplied, the recording signal REC Alternatively, the reproduction signal PLY is stopped.

In the above structure, when storing performance data, first, the storage mode switch 15 is turned on to output the recording signal REC. Next, when a rhythm start switch (not shown) is turned on and the keyboard 1 is played, the keyboard circuit 2 outputs a key code KC corresponding to the depressed key. When the key code KC is output, the tone signal forming circuit 9 outputs a tone signal, and as a result, the speaker 10 produces a tone corresponding to the depressed key.

When the recording signal REC and the key code KC are output, the writing control circuit 3 performs the above-described data writing operation on the data memory 5 and sequentially increments the address counter 6. Go on. In this case, when one of the light emitting diode Db ₁ to D b _n are turned on by signal SEL, because the OR gate 22 outputs "1" signal, the selector 20 selects the input terminal A, the selector 21 is input B Select the edge. As a result, the light emitting diode Da ₁ to DA _n are lighting control based on the output signal of the comparator 8d, In addition, the light-emitting diode Db ₁ Db _n performs display of the selected tone color.

[0017] Then, as described above, the value of the signal Adr according progression of the performance are sequentially incremented, this result, the light emitting diode Da ₁ to DA _n to light is of a lowermost end as play progresses From the top to the top one by one. In this case, the value of the signal Adr, since corresponding to the usage of the data memory 5, after all, the light-emitting diodes Da ₁ to DA _n, so that the display usage data memory 5.

Meanwhile, the Rutoki be turned by either the signal SEL of the light emitting diode Da ₁ to DA _n, because the OR gate 22 outputs "0" signals, the selector 20 selects the B input terminal, the selector 21 Select the A input terminal. As a result, performs a light emitting diode Da ₁ to DA _n are displayed for the selected tone in the same way as in the above, that displays the amount of memory on the basis of the output signal of the light emitting diode Db ₁ Db _n is comparators 8d ..

As can be seen from the above description, in this embodiment, the amount of memory used is displayed by using the diode on the side that does not display the selected tone color. Therefore, the player can perform the performance while grasping the memory usage amount, which eliminates the possibility of making an input error and allows the input performance to be performed extremely smoothly.

Further, if the input is over, the final address detection circuit 12 outputs the signal FUL L, so that the rhythm sound is stopped and the performer can know this. Next, when performing an automatic performance, the automatic performance mode switch 16 is turned on. As a result, the reproduction signal PLY is output and the read control circuit 7 starts the read operation. Therefore, the tone signal forming circuit 9 forms a tone signal based on the key code KC '. The automatic performance operation is similar to that of the conventional device.

In this embodiment, if each light emitting diode is a multi-color display light emitting diode and the memory usage amount is displayed, a display color different from the display of the selected tone color can be visually provided. It is more preferable because the distinction between the two becomes clear. Further, if the rhythm selection switch has an indicator by a light emitting diode similarly to the above-mentioned tone color selection switch, the same memory usage display as described above can be displayed on this indicator. ..

FIG. 4 is a block diagram showing the configuration of another modification of the embodiment. In this figure, 30 is a frequency divider for dividing the tempo clock TCLK,₁~ S_n By gate 31_-1~ 31_-nIt is designed to control opening and closing. In this case, output signal S₁Is the output signal with the largest frequency division ratio.₂, S ₃ , ……, S_nThe frequency division ratio is set to decrease in the order of. And gate 3 1_-1~ 31_-nIs connected to each output terminal of the comparator 8d, and the gate 3 1_-1~ 31_-nEach output terminal of is connected to the input terminal of the OR circuit 32. Further, the output terminal of the OR circuit 32 is connected to one input terminal of the AND gate 33, and the recording signal REC is supplied to the other input terminal of the AND gate 33. Reference numeral 34 is a display for displaying the performance memory mode, which is lit when the AND gate 33 outputs a "1" signal.

According to the configuration described above, when the value of the address signal Adr increases in the performance storage mode, first, the “1” signal is supplied to the input end of the gate 31 _-1 , and the “1” signal is supplied. Are intermittently supplied to the OR circuit 32 based on the cycle of the signal S ₁ . Then, the output signal of the OR circuit 32 is supplied to the display 34 via the AND gate 33, and as a result, the display 34 blinks in accordance with the cycle of the signal S ₁ . The blinking cycle of the indicator 34 in this case is a relatively slow blinking cycle because the frequency division ratio of the signal S ₁ is high.

Then, as the value of the address signal Adr of the data memory 5 increases, a “1” signal is sequentially input to its input end in the order of _gate 31 _-2 → 31 _-3 ... → 30 _-n. As a result, the display 34 blinks in the order of the signals S ₂ → S ₃ ... → S _n corresponding to the periods of these signals. That is, the blinking of the display 34 has a shorter cycle as the address signal Adr increases.

Therefore, in this modified example, as the usage amount of the data memory 5 increases, the blinking cycle of the display 34 becomes faster, and the performer can visually recognize this. .. Further, in this modification, there is an advantage that the usage amount of the data memory 5 can be displayed by one display.

In each of the above-described embodiments, the data is input by the real-time performance in the performance storage mode, but instead of this, the pitch data and the pitch data are stepwise input. You may. Further, in each of the above-described embodiments, the memory usage amount is displayed only when data is stored, but the memory usage amount may be displayed even during automatic performance (playback). In this case, there is an advantage that you can visually understand the progress of the song.

[0027]

[Effect of the device]

 As described above, according to the present invention, the memory usage amount is displayed when the performance is stored, and as a result, the operator can perform the input operation while grasping the memory usage amount, and at the time of the playback, the memory usage amount is also displayed. Since the usage amount is displayed, there is an effect that the progress status of the song can be visually grasped. Further, since the memory usage is displayed by using the tone parameter selection status display means, it is more cost effective than the case where a dedicated display device for displaying the memory usage is provided.
