〔Example〕

FIG. 1 is a block diagram showing the configuration of an electronic musical instrument to which an automatic performance device according to an embodiment of the present invention is applied. The electronic musical instrument shown in this figure has the following three tone generation modes.

(1) Melody mode This mode generates melody and rhythm sounds.
The entire key range of the (single-level keyboard) is the key range for melody sounds.

(2) ABC (Auto Bass Chord) Mode This mode generates melody sounds, accompaniment sounds, and rhythm sounds individually. In this mode,
Approximately one and a half octaves on the bass side of keyboard 1 are the key range for accompaniment sounds, and the remaining treble side is the key range for melody sounds. Note that in this example
There are two types of ABC available: fin guard code and single fin guard code. A Finguard chord is when you specify chord constituent notes by operating multiple keys in the accompaniment range of keyboard 1, a chord and its corresponding accompaniment, such as bass notes, are created based on the pitch of each key operated. the mode in which sound is formed,
In addition, a single finger chord means that when you specify the root note and chord type (major, minor...) of a chord in the accompaniment tone area of keyboard 1, the chord is detected based on that operation, and this detected chord is This is a mode in which accompaniment sounds such as chords and bass notes are formed.

(3) HP (hand percussion) mode This mode generates only rhythm sounds. In this mode, a plurality of predetermined keys on the keyboard 1 each correspond to a specific rhythm instrument (bass drum, bongos, maracas, etc.). and,
When one of the keys on the keyboard 1 is operated, the sound of the rhythm instrument corresponding to the key is generated.

This electronic musical instrument has the above three modes. Furthermore, this electronic musical instrument has both a function of converting the performance process by a performer into data and recording it in a memory, and a function of reproducing the recorded data (automatic performance function).

A detailed description will be given below based on the drawings. In FIG. 1, reference numeral 2 is an operator used for tone color setting, volume setting, effect setting, etc., and 3 is a rhythm select switch for selecting the type of rhythm (waltz, mambo, rumba, etc.). 4 is a rhythm start switch, and when this switch 4 is operated, the rhythm start signal RHYS becomes a "1" signal. 5 is a break switch, and when this switch 5 is operated, the break signal BR becomes a "1" signal while the switch 5 is operated, and the rhythm sound and accompaniment sound are stopped based on this "1" signal. 6 is
This is an ABC switch and turns on when a single finger code or finger code is selected. 7 is an HP switch, which is turned on when HP is selected. and,
If only ABC switch 6 is turned on, the above-mentioned
(2) ABC mode, when only HP switch 7 is on, (3) HP mode, and when both switches 6 and 7 are off, (1) melody mode.

8 is an oscillator that generates a tempo clock TCL, the frequency of which can be changed. The period of this tempo clock TCL corresponds to the length of a 16th note. 9 is a tempo counter and a tempo clock.
Count up TCL. This tempo counter 9 is reset when the rhythm start signal RHYS is a "0" signal, and its count output is supplied to the rhythm pattern generation circuit 10. Furthermore, this tempo counter 9 outputs a pulse signal FTP every time a quarter note period elapses, that is, every time the tempo clock TCL is counted by four.
The rhythm pattern generation circuit 10 is composed of a ROM (read only memory), and has internal memory blocks corresponding to each type of rhythm, and each memory block generates musical sounds of rhythm instruments. A data string (rhythm pattern) of "1" and "0" indicating timing is recorded corresponding to each rhythm instrument. Then, one of the memory blocks is selected by the output of the rhythm select switch 3, and each rhythm pattern in the selected memory block is sequentially read out in parallel based on the output of the tempo counter 9, and the automatic rhythm pattern is read out in parallel based on the output of the tempo counter 9. It is output to the OR circuit 11 as ORP. Further, this rhythm pattern generation circuit 10 includes:
Base pattern data BPD that switches the pitch of the auto bass sound in ABC mode and chord pattern data CPD that instructs the timing of the auto chord sound in ABC mode are recorded, and each of these data BPD and CPD is It is read out based on the output of the tempo counter 9, and detected and detected.
It is output to the distribution circuit 12.

The detection/distribution circuit 12 performs the following operations.

In melody mode (switches 6, 7, off), each operating state of keyboard 1 and controller 2 is detected every time a certain period of time elapses, and the key code data corresponding to the key being operated on keyboard 1 is stored as melody data MD. It also outputs melody operator data MSD indicating the operation state of the operator related to the melody sound of the operator 2 and rhythm sound operator data RSD indicating the operation state of the operator related to the rhythm sound.

In ABS mode (switch 6 on) As in the case above, keyboard 1 and controller 2
detects the operating state of the melody sound key area of keyboard 1, outputs melody data MD based on the operating state of the melody sound key area of keyboard 1, and outputs the melody operator data MSD described above.
and rhythm sound operator data RSD. Also, it generates a plurality of key code data constituting a chord based on the operation status of the accompaniment sound key area of keyboard 1, and converts this key code data into chord sound data.
It is output as a CD at the timing specified by the code pattern data CPD. Furthermore, it outputs chord sound operator data CSD in accordance with the operating state of the operator 2 related to the chord sound. In addition, the root note of the bass note is detected based on the operation status of the accompaniment note area, and this root note and bass pattern data are
Generates bass sound key code data based on BPD and outputs it as bass sound data BD. Furthermore, it outputs bass sound operator data BSD in accordance with the operation state of the operator related to the bass sound. moreover,
When any key in the accompaniment tone range is operated for the first time at the start of keyboard performance, a signal ABCON is output.

In the HP mode (switch 7 on), the operating state of the keyboard 1 is detected, and according to the detection result, hand percussion data HPD is output, as well as rhythm sound operator data RSD. In this case, hand percution data
The HPD has the same number of bits as the types of rhythm instruments, and each bit corresponds to a different rhythm instrument.
For example, when the key corresponding to the maracas on the keyboard 1 is operated, the bit corresponding to the maracas in the percussion data HPD becomes "1" (the other bits are "0"). The correspondence between this rhythm instrument and each bit is the same as the correspondence between each bit and rhythm instrument in the autorhythm pattern ORP.

Next, the OR circuit 11 generates percussion data.
Each bit of HPD and autorhythm pattern ORP
It takes an OR with each bit of , and outputs the result as rhythm data RD, and also outputs rhythm operator data RSD and break signal BR as data RSDBR. Selector 15-18
Each selects one of the data supplied to the input terminals A and B based on the signal supplied to the select terminal SB, and outputs the selected data. The gate circuit 19 controls the opening and closing of the output of the selector 15, and the gate circuit 20 controls the opening and closing of each output of the selectors 16 to 18, respectively. The musical sound signal forming circuit (musical sound signal forming means) 21 includes a melody sound forming section 21a, a chord sound forming section 21b, a bass sound forming section 21c, and a rhythm sound forming section 21d, and the musical sound signals formed in each section are The signals are mixed and supplied to the speaker 23 via the amplifier 22.

On the other hand, switches 25 to 32 are a melody record switch, a melody playback switch, a chord record switch, a chord playback switch, a bass record switch, a bass playback switch, a rhythm record switch, and a rhythm playback switch, respectively. 28, 29 and 30, and 31 and 32 are designed so that they are not turned on at the same time. Further, push button switches 33 and 34 are an edit switch and a pause switch, respectively. The outputs of these switches 25 to 34 are both supplied to a recording circuit 35. Further, the OR gate 36 is a circuit that takes the OR of each output signal of the melody recording switch 25, the chord recording switch 27, the bass recording switch 29, and the rhythm recording switch 31, and outputs the output from each of the AND gates 37 to 39 as a signal ANYREC. is supplied to the input terminal of

Next, the memory circuit 35 will be explained with reference to FIG. In this figure, circuit blocks 51 to 5
4 are circuits with the same configuration, and circuit block 5
1, a RAM (random access memory) a, a latch b, a set/reset flip-flop (hereinafter abbreviated as FF) d,
It is composed of a selector e, a RAM f, a selector g, an AND gate h, and an OR gate i. Note that the storage capacity of RAMs a and f in circuit block 54 is higher than that of other circuit blocks 51 to 53.
This is smaller than the storage capacity of RAMs a and f in the memory. Reference numeral 55 is a differentiating circuit, which outputs pulse signals P1 and P2 at the rise and fall of the rhythm start signal RHYS, respectively, and also outputs the pulse signals P1 and P2 at the rise and fall of the rhythm start signal RHYS.
Pulse signal P3 is output at the rising edge of ABCON. 56 is a trigger flip-flop (hereinafter referred to as
(abbreviated as TFF), 57 is an address counter. The count output of this address counter 57 is sent to the circuit block 51 as address data A1.
RAM・a and f address terminals in ~53
Furthermore, the lower X bits of address data A1 are supplied as address data A1a to address terminals AD of RAMs a and f in circuit block 54, respectively.

Next, the operation of the above-mentioned electronic musical instrument will be explained.

(1) For performance only (no data recording) In this case, the performer must first turn switches 25 to 32.
Both are off. switch 26, 28, 3
When switches 0 and 32 are turned off, the output signals MPLB, CPLB, BPLB, and RPLB of each switch become "0" signals, and this "0" signal is output to selector 1.
It is supplied to each selector terminal SB of 5 to 18. Thereby, the data of each input terminal A of the selectors 15-18 is outputted from each output terminal of the selectors 15-18. Next, the performer selects ABC and HP. Now, suppose ABC is selected (switch 6 on). Next, a desired tone, effect, etc., and rhythm are selected using the operator 2 and the rhythm select switch 3, and then the rhythm start switch 4 is turned on to begin playing the keyboard. When the rhythm start switch 4 is turned on, the rhythm pattern generation circuit 10 sequentially outputs the autorhythm pattern ORP. This autorhythm pattern ORP is output from the OR circuit 11 together with the rhythm sound operator data RSD output from the detection/distribution circuit 12, and is sent to the selector 18 and gate circuit 2.
0 to the rhythm sound forming section 21d.
The rhythm sound forming section 21d is an autorhythm pattern.
Based on the ORP and the operator data RSD, each internal rhythm sound source (corresponding to each rhythm instrument) is driven to generate a rhythm sound signal, and this rhythm sound signal is supplied to the speaker 23 via the amplifier 22. As a result, rhythm sounds are produced. Next, when the performer starts playing the keyboard, the aforementioned data MD, MSD, CD, CSD, BD,
Each BSD is output in parallel. And data
MD and MSD are supplied to the melody tone forming section 21a via the selector 15 and gate circuit 19, data CD and CSD are supplied to the chord tone forming section 21b via the selector 16 and gate circuit 20, and
Data BD and BSD are selector 17 and gate circuit 2
0 to the bass sound forming section 21c.
Melody sound forming section 21a, chord sound forming section 21
b. The bass sound forming section 21c forms a melody sound signal, a chord sound signal, and a bass sound signal based on each of the supplied data and outputs them. Each output musical tone signal is mixed with the rhythm tone signal and supplied to the speaker 23 via the amplifier 22. As a result, the melody sound from the speaker 23,
Accompaniment sounds (chord sounds and bass sounds) and rhythm sounds are produced. Note that when the break switch 5 is turned on during a performance, the break signal BR becomes a "1" signal, and this "1" signal is sent to the selector 1.
8 to the Noah gate 40. As a result, the output of the NOR gate 40 becomes a "0" signal, and as a result, the gate circuit 20 is closed, and the generation of chord sounds, bass sounds, and rhythm sounds is stopped.

(2) When recording the performance process In this case, the performer first presses switches 25 and 2.
7, 29, and 31 are each turned on. As a result, the signals MREC, CREC, BREC, and RREC each become a "1" signal. Then, this "1" signal is applied to each of the circuit blocks 51 to 54 of the memory circuit 35.
RAM・a and f read/write terminals RW
By being supplied to the circuit blocks 51 to 5
Both RAMs a and f in RAM 4 become writable. Next, after the performer performs the above-described setting operation of the operator 2, etc., he turns on the rhythm start switch 4 and plays the keyboard, and musical tones are generated from the speaker 23 in the same manner as in the above case.

On the other hand, when the rhythm start switch 4 is turned on and the rhythm start signal RHYS rises to a "1" signal, a pulse signal P1 is output from the differentiating circuit 55 (FIG. 2). This pulse signal P1 is supplied via the OR gate 59 to the set terminal S of the FF 60 and the reset terminal R of each FF d in the circuit blocks 51 to 54, thereby causing the FF 60
is set, and each FF·d is reset. When FF·d is reset, a "0" signal is supplied to the select terminals SA of selectors e and g, respectively. As a result, the data at each input terminal B of selectors e and g is output from the output terminal. Also, when FF60 is set, inverter 61
A “0” signal is output from the address counter 5.
It is supplied to the reset terminal R of No.7. This results in
The address counter 57 is released from its reset state and becomes ready for counting. On the other hand, TFF56
(Fig. 2) is reset in the initial state, and when the pulse signal P1 is output, the Q output signal becomes “0”.
It's at the traffic lights. Therefore, a "1" signal is output from the inverter 63, the AND gate 64 is opened, and the tempo clock TCL is supplied to the clock terminal CK of the address counter 57 via the AND gate 64. As a result, the address counter 57 sequentially increments the tempo clock TCL from the point in time when the "0" signal is supplied to its reset terminal R, and therefore outputs the address data.
A1 and A1a change sequentially at the timing of the tempo clock TCL.

Therefore, the melody data MD sequentially outputted from the detection/distribution circuit 12 after the rhythm start switch 4 is operated is controlled by the tempo clock TCL.
At the timing of , the RAM in the circuit block 51 is
The melody operator data is sequentially written to a.
The MSD is supplied to RAM.f via selector e, and is sequentially written into this RAM.f. Similarly, the chord tone data CD and the chord tone operator data CSD are stored in the RAM in the circuit block 52, respectively.
Base sound data BD and base sound operator data BSD are shown in a and f, respectively, in the circuit block 53.
Also, the OR circuit 11 is connected to RAM a and f in
Rhythm data RD and data output from
RSDBR is written to RAMs a and f in circuit block 54, respectively. Then, when the rhythm start switch 4 is turned off at the end of the performance of one song, the rhythm start signal RHYS falls to a "0" signal. At this falling point, a pulse signal P2 is output from the differentiating circuit 55, and the FF 60 is reset by this pulse signal P2, and therefore the address counter 57 is reset.

In addition, RAM・a in circuit blocks 51 to 53
and f each have a capacity sufficient to record data for one song, while circuit block 5
RAMs a and f in RAM 4 have a capacity that can store data for two measures of a song. This is because the rhythm sound repeats the same pattern every one measure or two measures.

(3) For data playback (automatic performance) In this case, the operator first selects switches 26 and 2.
8, 30, and 32 are in the on state, and switches 25,
29 and 31 are each turned off. This results in
Signals MPLB, CPLB, BPLB, RPLB are each “1” signal, signals MREC, CREC, BREC,
RREC each becomes a “0” signal. And the signal
When MPLB, CPLB, BPLB, and RPLB each become a “1” signal, each input terminal B of selectors 15 to 18
data is output from each output terminal.
Furthermore, when the signals MREC, CREC, BREC, and RREC each become a “0” signal, the circuit blocks 51 to 5
A “0” signal is supplied to the read/write terminal RW of RAM・a in 4, so RAM・a becomes readable, and a “0” signal is supplied to one input terminal of OR gate i. Ru. Next, when the operator turns on the rhythm start switch 4, a pulse signal P1 is output from the differentiating circuit 55.
As a result, FF.d is reset and FF60 is set. When FF.d is reset and its Q output signal becomes a "0" signal, the data at each input terminal B of selectors e and g are output from their respective output terminals. In addition, the output of the AND gate h becomes a "0" signal, and therefore a "0" signal is supplied to the read/write terminal RW of RAM f.
RAM f becomes readable. On the other hand, FF6
0 is set and the output of the inverter 61 is “0”
When the signal is reached, the reset state of the address counter 57 is released. After that, the address counter 57
sequentially counts up the tempo clock TCL supplied via the AND gate 64. As a result, address data A1 and A1a change sequentially at the timing of the tempo clock TCL, and each of the circuit blocks 51 to 54 changes accordingly.
Data in RAMs a and f are read out sequentially. Then, the melody data MD and RAM·f read out from RAM·a of circuit block 51
The melody operator data MSD read out from the selector g and outputted from the output terminal of the selector g are respectively supplied to the melody sound forming section 21a via the selector 15 and the gate circuit 19 shown in FIG. A melody sound signal is formed in section 21a. Similarly, circuit blocks 52-54
The data in RAMs a and f are respectively supplied to the chord tone forming section 21b, the bass tone forming section 21c, and the rhythm tone forming section 21d, whereby a chord tone signal, a bass tone signal, and a rhythm tone signal are respectively formed. Ru. These melody sound signals, chord sound signals, bass sound signals, and rhythm sound signals are supplied to the speaker 23 via the amplifier 22, thereby generating reproduced musical sounds.

Next, when the operator turns on the pause switch 34 for a short time during the data reproduction described above, the musical tone reproduction is temporarily stopped. That is, when the pause switch 34 is turned on for a short time, the signal
PAUSE becomes a “1” signal for a short time, and this “1”
The signal passes through the OR gate 66 (Figure 2) to TFF.
The signal is supplied to the trigger terminal T of 56. This results in
TFF56 is set and the Q output signal becomes a "1" signal. When the Q output signal becomes a "1" signal, the output of the inverter 63 becomes a "0" signal, and therefore the AND gate 64 is closed and the up-counting of the address counter 57 is stopped. Further, the Q output signal (“1” signal) of the TFF 56 is supplied as a signal PAU to the NOR gate 40 and inverter 41 shown in FIG. As a result, a "0" signal is output from the NOR gate 40 and the inverter 41, and these "0" signals close the gate circuits 20 and 19, thereby stopping the generation of musical tones.

Next, when the operator briefly turns on the pause switch 34 again, the TFF 56 is triggered again.
The Q output signal returns to a "0" signal. As a result,
The AND gate 64 is opened, the address counter 57 starts counting the tempo clock TCL again, and the gate circuits 19 and 20 are opened. As a result, musical tone reproduction is performed again.
Note that the above-mentioned restart of musical tone reproduction can be performed using the pulse signal P1 or P3 shown in FIG. In this case, the pulse signal P1 or P3 is transmitted to the TFF 56 via the OR gate 59, the AND gate 68 (open at this point), and the OR gate 66.
is supplied to the trigger terminal T of.

Also, with the pause switch 34 turned on and the musical tone playback stopped, the switches 25, 27, 2
Turn on 9, 31, switch 26, 28, 30, 3
2 is turned off, then the pause switch 34 is turned on again, the keyboard is played for a certain period of time, and then the pause switch 34 is turned on again, the switches 25 to 32 are returned to the playback state, and the pause switch 3
By turning on RAM 4 again, part of RAM a and f can be rewritten.

Note that the above-described pause switch 34 can of course be used during data recording. By turning on the pause switch 34 during data recording, data recording can be temporarily stopped.

Next, when the operator turns on the edit switch 33 for a short time during playback, a reproduced musical tone is generated based on the operating state of the operator 2, and
From this point on, the operation status of the operator 2 is sequentially recorded in the RAM.f. That is, when the edit switch 33 is turned on and the signal EDIT rises to a "1" signal, a "1" signal is supplied to the load terminal L of each latch b in the circuit blocks 51 to 54. As a result, the operator data MSD, CSD, BSD, which is output from the detection/distribution circuit 12 at that time,
RSD is loaded into each latch b in circuit blocks 51-54, respectively. Further, when the signal EDIT rises to a "1" signal, FF.d is set and its Q output signal becomes a "1" signal. As a result, the data at each input terminal A of selectors e and g is output from each output terminal. Further, the output of the AND gate h becomes a "1" signal, and therefore the output of the OR gate i becomes a "1" signal, and the RAM f becomes in a writable state. As a result of the above, after the edit switch 33 is turned on, the latch b
The operator data written in is supplied to the musical tone signal forming circuit 21 via the selector g, and therefore,
A musical tone based on the operator data in latch b, in other words, a musical tone based on the operation state of operator 2 at the time when edit switch 33 was operated. Furthermore, after the edit switch 33 is turned on, the operator data in the latch b is supplied to the RAM f via the selector e, and this operator data is transmitted every time the count output of the address counter 57 changes. They are sequentially written into RAM f.

Next, when the reproduction of one musical tone is completed, the rhythm start switch 4 is turned off. When the rhythm start switch is turned off, the signal RHYS falls to a "0" signal, and at the time of this falling, the pulse signal P2 is output from the differentiating circuit 55. As a result, the FF 60 is reset, the address counter 57 is reset, and the musical tone reproduction ends.

Finally, and gates 37 to 3 in FIG.
9, 43, the OR gate 45 and the LED (light emitting diode) 44 will be explained. switch 25,
When any one of 27, 29, and 31 turns on (that is, when it enters the data recording state), the signal
ANYREC becomes a "1" signal, and this "1" signal is supplied to AND gates 37-39, respectively. In this state, the pause switch 34 is operated, the signal PAU becomes a "1" signal, and this "1"
The signal passes through the OR gate 45 to the AND gate 43
supplied to As a result, the AND gate 43 is closed, and the pulse signal FTP is supplied to the high-hat sound input terminal HHC of the rhythm sound forming section 21d and the LED 44 via the AND gate 43, thereby producing a high-hat sound at the timing of a quarter note. occurs repeatedly, and the LED 44 blinks.
Similarly, when the signal STOP becomes a "1" signal (when the address counter 57 is reset) or when the break signal BR becomes a "1" signal while the signal ANYREC is a "1" signal, , a high-hat sound is generated at the timing of a quarter note, and the LED 44 blinks. In addition, the generation of this high-pitched sound and the flashing of LED 44,
This function is provided to allow the performer to keep up the rhythm when musical sounds (especially rhythm sounds) are stopped.

The details of the embodiment shown in FIGS. 1 and 2 have been described above. In the above explanation, we have explained the case where all the melody sounds, chord sounds, bass sounds, and rhythm sounds are recorded and played back. However, for example, it is also possible to record only the rhythm sounds or play back only the chord sounds. Of course, this is also possible, and for example, it is also possible to record melody sounds and reproduce chord sounds at the same time. Furthermore, data recording can also be started by operating a keyboard in the accompaniment tone range. In other words, when ABC is selected, if you operate the keys in the accompaniment range,
The detection/distribution circuit 12 outputs a signal ABCON, and at the rise of this signal ABCON, the differentiator 55 outputs a pulse signal P2. and,
Data recording starts when this pulse signal P2 is output from the OR gate 59. In addition, in the embodiment described above, the melody data
MD, melody controller data MSD, etc. are recorded in RAM・a and f every time a certain period of time elapses, but instead of this, each time the operation status of keyboard 1 and controller 2 changes, the The time since the time of change and the state of the changed portion may be recorded respectively. In addition, in the embodiment described above,
For example, when a single finger chord is selected, the detection/distribution circuit 12 generates key code data constituting chords and bass notes.
is configured to output the key code data of the key operated in the accompaniment tone key area as is, and also stores this key code data, base pattern data BPD, chord pattern data CPD, and rhythm operator in the memory circuit 35. The data RSD may be stored respectively, and upon reproduction, key code data for chords and bass notes may be generated in the tone signal forming circuit 21 based on the above-mentioned respective data.
