[Detailed Description of the Invention] This invention provides automatic performance based on performance data input from a recording medium and an actual performance (live performance).
The present invention relates to an electronic musical instrument equipped with an automatic performance device that allows an arbitrary combination of automatic performance by recording and reproducing the live performance for each part.

Conventionally, performance data (for example, digital data in which pitch data, note length data, etc. of each note are arranged) corresponding to the musical score of a desired song is input from a recording medium such as a magnetic tape and stored in advance. 2. Description of the Related Art Electronic musical instruments are known that include an automatic performance device that sequentially reads performance data to form musical tones. In this type of electronic musical instrument, during automatic performance, automatic performance of a desired part is prohibited, and only this part is actually played using the keyboard etc. to perform an ensemble performance (i.e., minus-one performance). . In addition, other conventional electronic musical instruments include
Some devices are equipped with an automatic performance device that records an actual performance using a keyboard or the like in the form of performance data, and reproduces the performance by reproducing the data. Even in such electronic musical instruments, there are cases in which a plurality of parts are actually played and recorded in advance, and then these parts are played back and other parts are actually played for an ensemble performance.

By the way, it would be convenient if one electronic musical instrument could perform the two types of automatic performance described above selectively or in a desired combination for each part. It would be even more effective if the automatic performance of the desired part based on the actual performance could be combined with the actual performance, and the actual performance could be recorded and played back.

Therefore, the present invention provides an automatic performance based on performance data input from a recording medium, an actual performance,
To provide an electronic musical instrument with an automatic performance device capable of automatically performing automatic performance by recording and reproducing actual performance using one device and in arbitrary combinations for each part of a musical piece.

Then, when the start of automatic performance is commanded, the first performance data is transferred from the performance data memory 1 for each part (i.e., melody,
The data is read out in parallel for each chord and bass) and in the order of progression of the song, and among these read data, only the data belonging to the parts that are not prohibited by the switches _3u , _3l , and _3p are read out. A musical tone signal is formed by a musical tone signal forming circuit 4 (musical tone forming means), and is emitted from a speaker 5. In addition, the key switch circuits 6 _u , 6 _l , and 6 _p are key codes indicating the keys to be pressed on the upper keyboard (UK), lower keyboard (LK), and foot keyboard (PK) of a keyboard (not shown).

Then, when a performance is performed with recording specified by the switch 8, only the parts that belong to the parts prohibited by the switches _3u , _3l , and _3p are played on the key. The performance data is recorded in the data memory 7 as performance data; on the other hand, when the start of automatic performance is commanded with the switch 9 specifying playback, the performance data is read out from the key performance data memory 7;
Of these data, the musical tone signal forming circuit 4 generates a corresponding musical tone signal from only those data belonging to the parts prohibited by the switches 3 _u , 3 _l and 3 _p .

For each part, the data uses a key code KC indicating the pitch of each note and note length data LND indicating the note length, and for parts that correspond to chords, indicates the chord name and root note of each chord. The songs are recorded in the order of progression using chord data HD and note length data LND indicating note length. Note that the recording medium 2 may be a musical score or the like on which performance data is printed using a bar code. The reading device 10 is a device that reads the performance data from the magnetic tape, and the read performance data is stored in the performance data memory 1.
supplied to Performance data memory 1 includes areas 1 _u1 and 1 u2 for storing performance data corresponding to melodies, ie, parts to be played on the upper keyboard, and areas 1 u1 and 1 _u2 for storing performance data corresponding to chords, ie, parts to be played on the lower keyboard. Area 1 _l1 , 1 _l2 ,
Areas 1 _p1 and 1 _p2 for storing performance data corresponding to the parts to be played on the bass, that is, the foot keyboard.
are provided in each of these areas 1 _u1 , 1 _u
2 , 1 _l1 , 1 _l2 , 1 _p1 and 1 _p2 are stored with the performance data as shown in FIG. That is, each address in area 1 _u1 contains the key code KC _u-1 ~ _{KC uo} of each note of the melody, and each address in area 1 _u2 contains the note length data LND _u-1 ~
LND _uo is memorized in the order in which the song progresses. In addition, each address in area 1 _l1 contains chord data (data indicating the chord name and root note) HD _-1 to HD _-n for each chord, and each address in area 1 _l2 contains note length data for these chords.
LND _l-1 to LND _ln are stored in the order of song progression.
In addition, areas 1 _p1 and 1 _p2 contain key codes KC _p-1 to KCP _-k and note length data for each bass note.
LND _p-1 to LND _pk are stored in the same way.

Next, the read command circuit 11 (read means) is a circuit that instructs the performance data memory 1 to read out the performance data, and is for reading melody pitch, reading melody note length, reading chord data, and reading chord data. It is configured with a total of six address counters for length reading, bass pitch reading, and base note length reading. When the start of automatic performance is instructed to these address counters, each of the areas 1 _u1 , 1 _u2 , 1 _l
Values indicating the starting addresses of ₁ , 1 _l2 , 1 _p1 , and 1 _p2 are set. The values of these address counters are then sent to the performance data memory 1 along with the read command signal.
are sequentially supplied as address data to. Then, the areas 1 _u1 , 1 _u2 , 1 _l1 , 1 _l2 , 1 _p1 , 1 _p
2 , that is, KC _u-1 ,
LND _u-1 , HD _-1 , LND _l-1 , KC _p-1 , and LND _p-1 are sequentially read out and supplied to the distribution circuit 12 . The distribution circuit 12 selects the key code KC _u (KC _u-1 in this case) corresponding to the melody from among these data.
and note length data LND _u (LND _u-1 in this case) to the preceding tone register 13 _u and the note length measurement circuit 14.

(HD _-1 in this case) and note length data LND _l (LND _l-1 in this case) to the chord key code generator 15.
and the note length measuring circuit 14, and also supply the key code KC _p (KC _p-1 in this case) and note length data LND _p (LND _p-1 in this case) corresponding to the bass to the preceding tone register 13p and The signal is supplied to the note length measuring circuit 14. The note length measuring circuit 14 is connected to the tempo oscillator 1.
It has a total of three preset counters, one for melody, one for chord, and one for bass, which subtract and count the tempo clock TCLK output by 8. The note length data LND _u (LND _u-1 in this case), Set LND _l (LND _l-1 in this case) and LND _p (LND _p-1 in this case) to each of these preset counters. Further, the chord key code generator 15 converts the chord data HD (HD _-1 in this case) into a key code KC _l (for example, three key codes) of each constituent note of the chord indicated by this data and outputs it. These key codes KC _l (in this case, KC _l-1 corresponding to HD _-1 ) are supplied to the preceding sound register 13l. The registers 13 _u , 13 _l , 13 _p have these key codes KC _u (KC _u-1 ), KC _l (KC _l-1 ), KC _p (KC _p-1 ).
are each captured and temporarily stored. Immediately after the start of automatic performance is instructed, the read command circuit 11, following the above-described operation, operates the address counters for reading the melody pitch, the chord data, and the bass pitch. Increment. Therefore, in this case, the contents of the second address of areas 1 _u-1 , 1 _l-1 , 1 _p-1 from performance data memory 1, that is, KC _u-2 , HD _-2 , KC _p-2 is then read out. As a result, register 13 _u ,1

KC _l-2 and KC _p-2 are supplied. In this case, these registers 13 _u , 13 _l , 13 _p and the current sound register 16 provided at the next stage of these registers
_u , 16 _l , and 16 _p capture and hold input data at once. Therefore, in this case, register 13
_u , 13 _l , 13 _p have key codes KC _u-2 , KC _l-2 ,
KC _p-2 is held in registers 16 _u , 16 _l and 16 _p , and key codes KC _u-1 , KC _l-1 and KC _p-1 are held in registers 16 u , 16 l and 16 p, respectively.

On the other hand, when the subtraction counting operation of each preset counter of the note length measuring circuit 14 progresses and the content of the melody preset counter changes to "0", that is, the note length data LND _u (in this case
When the mark length indicated by LND _u-1 ) has elapsed, the mark length measuring circuit 14 outputs a pulse signal NEXT _u . This signal NEXT _u uses its rising edge to increment the melody pitch reading address counter and melody note length reading address counter in the read command circuit 11, and uses its falling edge to increment the register 13 _{u. . _ _} And note length measurement circuit 14
repeats the above operation. In addition, in exactly the same way, this note length measuring circuit 14 calculates the note length indicated by the note length data LND _l or LND _p every time the content of the chord preset counter or the bass preset counter changes to "0". Every time the time elapses, a pulse signal NEXT _l or NEXT _p is output. These signals NEXT _l or NEXT _p increment address counters for reading chord data, reading chord note length or bass pitch, and reading base note length in read command circuit 11, and registers 13 _l and 16 _l. Or command 13 _p and 16 _p to import input data.

Thus, registers 16 _u , 16 _l , 16 _p have
The key codes for each note of melody, chord, and bass are held in the order of progression of the song while measuring the note length, and registers 13 _u , 13 _l , and 13 _p hold the key codes that follow these key codes, respectively. be done.

The outputs of the registers 16 _u , 16 _l , and 16 _p are supplied to input terminals I _a , I _b , and I _c of the gate circuit 17, respectively. On the other hand, switches 3 _u , 3 _l , 3 _p
are push buttons 3U, 3 on the panel as shown in Figure 3.
Alternate switches operated by L and 3P (controllers for inhibiting musical sound formation) correspond to inhibiting upper keyboard sounds (melody), lower keyboard sounds (chords), and foot keyboard sounds (bass), respectively. ing. Each of these switches 3u, 3l, and 3p is adapted to output a "1" signal when in the on state (closed state).
The output signals of these switches 3 _u , 3 _l , 3 _p are inverted by inverters 19 _u , 19 _l , 19 _p , and the control input terminals a, b, c of the gate circuit 17 are inverted by inverters 19 u, 19 l, 19 p.
are supplied to each. When a "1" signal is supplied to the control input terminal a, the gate circuit 17 outputs the signal of the input terminal I _a from the output terminal O _a , and outputs "1" to the control input terminal b.
When a signal is supplied, the signal from the input terminal I _b is output from the output terminal O _b , and when a "1" signal is supplied to the control input terminal C, the signal from the input terminal I _c is output from the output terminal O _c . It is composed of Therefore, from this gate circuit 17, among the key codes outputted by the registers 16 _u , 16 _l , 16 _p , the switches 3 _u , 16 p
Only those corresponding to the off-state switches at 3 _l and 3 _p are output and supplied to the channel allocation circuit 20 . This channel assignment circuit 20 assigns each key code supplied from the gate circuit 17 and other key codes to be described later, such that those corresponding to a melody are assigned a unique timing to the melody, and those corresponding to a chord are assigned to a chord. It outputs time-divisionally and periodically at the assigned unique timing, and those corresponding to the base at the unique timing assigned to the base. The musical tone signal forming circuit 4 has a plurality of musical tone forming channels for each of the melody, chord, and bass parts, and assigns each key code supplied from the channel allocation circuit in a time-sharing manner to each corresponding one. The signals are sequentially captured and held in the musical tone signal forming channel. Each of these musical tone signal forming channels forms a musical tone signal having a tone pitch corresponding to the input key code and a preset tone color. After these musical tone signals are mixed, they are outputted from the musical tone signal forming circuit 4 and supplied to the amplifier 21. On the other hand, the amplifier 21 is supplied with a rhythm sound signal synchronized with the tempo lock TCLK from an autorhythm circuit 22. Therefore, the amplifier 21 amplifies a composite signal of the musical tone signal and the rhythm tone signal and supplies the amplified signal to the speaker 5.

By the way, each of the registers 13 _u , 13 _l , and
The output of _13p is also supplied to key indicators _23u , _23l , and _23p . The key display 23 _u has the same number of lamps (or light emitting elements such as light emitting diodes) as the keys provided in one-to-one correspondence with each key of the upper keyboard.
A display device that uses these lamps to instruct keys to be pressed on the upper keyboard, decodes the key code output from the register 13 _u , and, based on the decoding result, selects one of the lamps corresponding to the key code. Only the object is made to emit light on the condition that a "1" signal is supplied to its enable terminal E. In addition, other key display devices 23 _l ,
_23p is also configured in the same manner as the key display _23u , and indicates which key to press among the lamps corresponding to the lower keyboard and foot keyboard, depending on the key code output from the registers _13l and _13p . It is designed so that only those corresponding to the light will emit light. The switch 24 is for prohibiting or permitting each of the lamps to emit light, and is an alternate switch linked to a lamp-off command push button 24' shown in FIG. The output signal of this switch 24 is "1" in the on state.
It becomes "0" in the off state, and after being inverted by the inverter 26, each of the key indicators 2
3 _u , 23 _l , and 23 _p are supplied to enable terminals E.

According to the part described above, when automatic performance is commanded, the performance data are sequentially read out from the performance data memory 1, and among these performance data, among the switches 3 _u , 3 _l , and 3 _p, Only the musical tone signal of the part corresponding to the off state is formed, and this musical tone signal and the rhythm tone signal are synthesized and produced. In this case, if the switch 24 is in the OFF state, the key of the musical tone to be sounded next to the musical tone currently being sounded will be displayed among the key press indication lamps corresponding to the upper keyboard, lower keyboard, and foot keyboard. Corresponding items will be published sequentially.

Next, the key switch circuit 6 _u has the same number of key switches as the keys that correspond one-to-one to each key of the upper keyboard, and a decoder etc. that decodes the output of these key switches, and indicates the pressed key of the upper keyboard. This is a circuit that creates and outputs a key code KC′ _u . Also,
The key switch circuits 6 _l and 6 _p are constructed similarly to the key switch circuit 6 _u , and output a key code KC' _l indicating a pressed key on the lower keyboard, and a key code KC' _p indicating a pressed key on the foot keyboard, respectively. I'm starting to do that. These key codes KC' _u , KC' _l , KC' _p are supplied to the channel assignment circuit 20, and according to the same operation as described above, these key codes KC' _u , KC' _l , KC'
Each musical tone signal corresponding to _KC'p is formed by the musical tone signal forming circuit 4. Also, these key codes
KC′ _u , KC′ _l , KC′ _p are input terminals of the gate circuit 27
It is also supplied to I _a , I _b , and I _c . On the other hand, switch 8 is
This switch is used to instruct recording of the actual performance using the upper keyboard, lower keyboard, and foot keyboard, and is an alternate switch linked to the recording command push button 8' shown in FIG. The output signal of this switch 8 is "1" in the on state and "0" in the off state, and is supplied to the first input terminals of the AND gates 28 _u , 28 _l , and 28 _p . Furthermore, the output signals of the switches 3 _u , 3 _l , 3 _p are supplied to the second input terminals of the AND gates 28 _u , 28 _l , 28 _p . Therefore, the output signals of these AND gates 28 _u , 28 _l , 28 _p are output from the switches 3 _{u , 28 p} on the condition that the switch 8 is in the on state.
Of 3 _l and 3 _p , only the one corresponding to the on state becomes "1". These output signals are supplied to control input terminals a, b, and c of the gate circuit 27, respectively.
This gate circuit 27 is similar to the gate circuit 17 described above.
It is constructed in the same way as . Therefore, from this gate circuit 27, if the switch 8 is on, the key switch circuits 6 _u , 6 _l ,
Among the key codes KC' _u , KC' _l , KC' _p outputted by the switch 6 _p , the one corresponding to the on-state switch in the switches 3 _u , 3 _l , 3 _p (that is, the one in the performance data memory 1 Only those corresponding to parts for which musical tone formation from performance data is prohibited are output and supplied to the event detection circuit 29. This event detection circuit 29 includes a gate circuit 2
Each key code supplied from 7 is monitored, and if any of these key codes changes, that is, an event occurs, all key codes being supplied at that time are updated with the source of these key codes. Each keyboard (UK, LK, PK)
It is output sequentially and all at once with an identification mark attached to it. These key codes with identification marks are used for timekeeping and
The signal is supplied to the write control circuit 30. This timekeeping/writing control circuit 30 has a timer circuit, that is, an event interval measuring counter that adds and counts the tempo clock TCLK and is cleared to zero each time the key code with identification mark is supplied. When the timekeeping/writing control circuit 30 is supplied with the key codes with identification marks from the event detection circuit 29, the timing/writing control circuit 30 receives the key codes with identification marks,
The value immediately before the counter is cleared to zero and time data with an identification mark are sequentially output and supplied to the data input terminal D _i of the key performance data memory 7. Further, this timekeeping/writing control circuit 30 synchronizes with each output of the above-mentioned key code with identification mark and time data.
Pulse signals WT are sequentially supplied to the write/read command circuit 31 (write/read means). Write/read command circuit 31
is preset to a value indicating the starting address of the key performance data memory 7 at the time when the start of recording of an actual performance using the keyboard or the start of automatic performance is commanded, and is preset by the signal WT or the signal RD described later. It has an address counter that is incremented, and outputs the value of this address counter, that is, address data, and also commands writing and reading of the key performance data memory 7. The key performance data memory 7 is composed of, for example, a RAM, and when the write/read command circuit 31 commands writing, it writes the data at the data input terminal D _i to the address indicated by the write/read command circuit 31, and When the write/read command circuit 31 issues a read command, the data at the address indicated by the write/read command circuit 31 is read out and output from the data output terminal D _p .

Therefore, in this key performance data memory 7,
When the switch 8 is turned on and the performance is started by instructing to start recording the performance using the keyboard,
The key performance data (second performance data) indicating the process of this performance are the key codes KC' _u , KC' l , KC' _l ,
It is stored as shown in FIG. 4 using KC' _p and time data indicating each event interval. In addition,
This figure 4 shows the keys of the upper keyboard (the key code is
The following example shows the case where KC′ _u-1 ) is held down for a time _Δt1 , and then the same key and a key on the foot keyboard (key code KC′ _p-1 ) are held down for a time _Δt2 . There is. Also, “UK” and “PK” in this diagram are the keyboard identification marks,
Further, "T" indicates an identification mark meaning that the event interval is stored.

Next, when the start of automatic performance is commanded, a value indicating the starting address of the key performance data memory 7 is preset in the address counter of the write/read command circuit 31, and thereby this key performance data The data at the first address of the memory 7 is read out and supplied to the clock/read control circuit 32. This timing・
The read control circuit 32 has a timer circuit, that is, a preset counter for counting and subtracting the tempo clock TCLK. This timing/readout control circuit 32 inputs the output data of the key performance data memory 7, and if this data is a key code with an identification mark, this data is sent to the distribution circuit 33.
At the same time, the signal RD is output, data at the next address is read from the key performance data memory 7, and the same process as described above is performed. Furthermore, when the input data is time data, this time measurement/read control circuit 32 sets this data in the preset counter, and continues to read the signal RD until the value of the preset counter reaches "0". Pause the output. Therefore, this time measurement/readout control circuit 32
From then on, key codes with identification marks are sequentially output according to the event interval. The distribution circuit 33 distributes these key codes with identification marks to each keyboard according to their identification marks, and those corresponding to the upper keyboard are sent to the register 34 _u , those corresponding to the lower keyboard are sent to the register 34 _l , and those corresponding to the foot keyboard are sent to the register 34 u. The corresponding ones are respectively supplied to the register _34p . These registers 34 _u , 34 _l , 34 _p temporarily hold each supplied key code, and input terminals I _a , I _b ,
Supply each to I _c . On the other hand, the switch 9 is used to specify whether or not to play a musical tone based on the key performance data read from the key performance data memory 7 during automatic performance, and is a push button 9' shown in FIG. This is an alternate switch linked to the (playback designation control). The output signal of this switch 9 is "1" in the on state and "0" in the off state.
, and the AND gates 36 _u , 36 _l , 36 _p
are supplied to each first input terminal of. Furthermore, the output signals of the switches 3 _u , 3 _l , 3 _p are supplied to the second input terminals of the AND gates 36 _u , 36 _l , 36 _p , respectively. Therefore, the output signals of these AND gates 36 _u , 36 _l , and 36 _p correspond to those of the switches 3 _u , 3 _l , and 3 _p that are in the on state, provided that the switch 9 is in the on state. Only those that do will be “1”. These output signals are then supplied to control input terminals a, b, and c of the gate circuit 35, respectively. This gate circuit 35 is configured similarly to the gate circuit 17 described above. Therefore _, when the switch 9 is on, the gate circuit 35 outputs each key code (key code KC _{' u ,} KC' _l , KC _{' p} ) corresponding to the switches _3u , 3l, and 3p that are in the on state (i.e., the keycodes corresponding to the keys in the ON state of the switches 3u, _3l , and _3p (i.e., the keycodes corresponding to the keys that are prohibited from forming musical tones from the performance data in the performance data memory 1). (corresponding to the part in question) is output and supplied to the channel allocation circuit 20.

According to the above-mentioned part, when automatic performance is commanded, data from the key performance data memory 7 is
_The key performance data corresponding to the actual performance as shown in _{FIG .} The signal is supplied to the channel allocation circuit 20. On the other hand, among the performance data read out from the performance data memory 1, the channel allocation circuit 20 stores switches _3u , _3l , _3p.
Among them, the one corresponding to the one in the off state (provided that the performance data is stored in advance),
In addition, key codes KC' _u , KC' _l , KC' _p outputted by the key switch circuits 6 _u , 6 _l , 6 _p (provided that a performance is performed using a keyboard) are respectively supplied. Therefore, musical tones corresponding to all these key codes are formed and produced together with the rhythm tones.

In addition, in FIG. 1, the switch 37 is
This is linked to the push button 37' (TEMPO FREE) shown in the figure, and when it is turned on, the TEMPO
(“1” signal) is output. When this signal TEMPO is output, each key code KC _u , KC _l , KC _p read from the performance data memory 1 and each key code generated by actually performing the performance.
KC′ _u , KC′ _l , and KC′ _p are compared, and it is determined whether or not the key operation is accurate.
Based on this determination result, the tempo clock is
The cycle of TCLK is changed to the optimum cycle, or the progress of automatic performance is paused until the correct key is pressed. Also, switch 38
is push button 38' (REPEATSET) shown in Figure 3.
It is linked to the signal in the on state.
Outputs REPEAT (“1” signal). this signal
When REPEAT is output, only a pre-specified section of the stored performance data is automatically played repeatedly. In other words, in this case, after specifying the number of the first phrase and the number of the last phrase of the desired automatic performance section in advance by operating the key or controller to which the phrase number is assigned, automatic performance is started. command. Then, the first
In the second automatic performance, the performance data in the performance data memory 1 begins to be read out at high speed, and the search for the first phrase is performed based on the result of this readout. When the first phrase is searched for, the performance data reading speed is switched to the normal performance tempo, and automatic performance is thereby performed until the last phrase is detected. In this case, a read address corresponding to the first phrase and a read address corresponding to the last phrase are respectively stored. In the second and subsequent automatic performances, only the performance data between these two addresses are read out and the automatic performances are performed.

In the embodiments described above, the recording medium 2 is a magnetic tape (or a musical score with a barcode printed on it, etc.). It may also be used as a memory pack. In this case, the reading device 10 becomes unnecessary, and instead of the performance data memory 1, this memory pack can be connected. Furthermore, although the key performance data memory 7 has also been described as a RAM, a writing/reading device is provided in the key performance data memory 7, and this writing/reading device is used to store keys on a magnetic tape, magnetic disk, etc. Performance data may also be written or read.

As is clear from the above description, the electronic musical instrument with an automatic performance device according to the present invention includes a first memory device for storing first performance data input from a recording medium, and reading means for this memory device;
a second memory device for storing second performance data created from an actual performance; a writing/reading means for the memory device; and formation of musical tones for each part of an automatic performance based on the first performance data. It is equipped with an operator for prohibiting musical sound formation and an operator for specifying recording and playback for specifying whether to record or reproduce the actual performance, and the actual performance is controlled by the operator for prohibiting musical sound formation. Since the recording or playback specified by the recording/playback designation control is performed only for parts whose musical tones are prohibited from being formed by the control, the performance data input from the recording medium is The automatic performance based on the performance, the actual performance, the record of this actual performance, and the automatic performance performed by reproducing this recorded performance are all 1.
It can be performed in any combination for each part using a single electronic musical instrument. Further, according to the present invention, the number of operators for determining the above-mentioned combinations can be kept to the minimum necessary number.
