Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic performance device suitable for use in demonstration performances of electronic musical instruments, and more particularly to an improvement in the music selection section.

[Summary of the Invention] The present invention selects performance data of a song that matches the performance conditions (or accompaniment conditions) related to the selection in conjunction with the selection operation of performance conditions such as timbre (or accompaniment conditions such as rhythm patterns). ,
By reading out the music, effective demonstration performances can be easily performed.

[Prior Art] Conventionally, automatic performance devices used for demonstration performances of electronic musical instruments operate a tone selection switch on the instrument panel to select a desired tone, and then turn on a performance start switch to play multiple songs from memory. There is a known device that sequentially reads out performance data and automatically plays the plurality of songs in sequence.

In this case, in addition to the tone selection switch, it is also possible to operate the rhythm selection switch to select the desired rhythm and then turn on the performance start switch.
Automatic performance is performed with autorhythm accompaniment.

[Problems to be Solved by the Invention] According to the above-mentioned conventional technology, a song that is not suitable for the selected tone (or rhythm pattern) may be automatically played, and the advertising effect of the musical instrument may be particularly poor during demonstration performances at stores etc. There was an inconvenience that damaged the

To deal with such a problem, it would be possible to select the tone color etc. in consideration of the content of the music to be performed, but it is unrealistic to expect such operations from store staff.

Furthermore, as a means of automatically setting a tone suitable for each piece of music to be performed, a method is known in which tone data is added to the beginning of the performance data and the tone is set based on the tone data when the performance starts. , it is conceivable to apply this to automatic performance devices such as those mentioned above. However, although such an automatic performance device has the advantage that each side is played with a tone suitable for it, the tone is automatically set for each song and the performance progresses, so for example, when playing an instrument, Even if one wishes to perform a demonstration performance by selecting a particular tone that is a selling point, there is an inconvenience in that this cannot be carried out.

An object of the present invention is to eliminate the above-mentioned inconveniences and to facilitate effective demonstration performances.

[Means for Solving the Problems] A first automatic performance device according to the present invention includes a selection operation means operated to select any one of a plurality of performance conditions such as timbre, and a selection operation means operated to select any one of a plurality of performance conditions such as timbre. A selective reading means is provided for selecting and reading performance data of a piece of music that is compatible with the selected performance conditions from the storage means, and automatic performance is performed in accordance with the selected performance conditions and based on the read performance data. It is characterized by:

Further, the second automatic performance device according to the present invention includes a selection operation means operated to select any one of a plurality of accompaniment conditions such as a rhythm pattern, and a selection operation means operated to select an arbitrary accompaniment condition from among a plurality of accompaniment conditions such as rhythm patterns. A selection reading means is provided for selecting and reading performance data of a suitable song from the storage means, and automatic performance is performed based on the performance data read out, and automatic accompaniment is performed according to the selected accompaniment condition. This is a characteristic feature.

[Function] According to the configuration of the present invention, in conjunction with the selection operation of the performance condition (or accompaniment condition), performance data of a song that matches the performance condition (or accompaniment condition) related to the selection is selected and read out. Therefore, songs that do not match the selected performance conditions (or accompaniment conditions) will not be automatically played. Further, the troublesome operation of selecting performance conditions (or accompaniment conditions) in consideration of the content of the music to be performed is also eliminated. Further, since any performance condition (or accompaniment condition) can be selected by the selection operation means, for example, by selecting a specific tone and performing a demonstration performance, it is possible to fully emphasize the quality of the tone.

[Embodiment] First Stream Side (FIG. 1) FIG. 1 shows a circuit configuration of an electronic musical instrument equipped with an automatic performance device according to a first embodiment of the present invention.

The keyboard 10 includes a large number of keys for manual performance, and is adapted to transmit key information indicating the pressed keys.

The keyboard performance sound forming circuit 12 forms a musical sound signal corresponding to a pressed key based on key information from the keyboard 10, and the formed musical sound signal is supplied to the speaker 16 via the output amplifier 14. It is emitted as a musical sound. Therefore, manual performance sounds can be generated by operating the keyboard 10.

There is a tone/rhythm selection switch T on the panel of the electronic musical instrument.
R3, tone selection switch TS (1) to TS (n),
Start switch STS, stop switch SPS
, rhythm selection switches R3(1) to R3(m), etc. are provided.

The tone/rhythm selection switch TR3 is operated to link automatic performance music selection with either tone selection or rhythm selection.When turned on, music can be selected in conjunction with rhythm selection, and when turned off, tone selection is linked. It becomes possible to select songs in conjunction with the selection.

The tone selection switches TS (1) to TS (n) correspond to the tone names of piano, chamber mouth, bassoon, respectively, and from these switches, you can select the tone that specifies the tone corresponding to the switch that is turned on. Specified data TS
D is now taken out.

The start switch STS and the stop switch SPS are both self-resetting pushbutton switches, and are used to command the start and stop of automatic performance, respectively.

Rhythm selection switches R3 (1) to R3 (m) correspond to the rhythm names of disco, waltz, etc. data RSD
is now being taken out.

Performance data memory for one day is - For example, ROM (read/lead/
(only memory), and stores performance data for many songs. The stored performance data for a large number of songs includes performance data for songs that suit the tones of selectable pianos, chamber mouths, and bassoons, as well as one selectable rhythm of disco, waltz, and ballad. Contains performance data for each suitable song. In this case, the number of memorized pieces is not necessarily n, since a particular song may be suitable for example to the tone of a piano and a chamber mouth, or may be suitable for a piano tone and a waltz rhythm.
It will not be +m.

The start address memory 20, for example, is made up of a ROM, and stores the start address in the memory 18 for each selectable tone color for performance data of a song suitable for that tone color.

When a desired one of the tone color selection switches TS (1) to TS (n) is turned on, tone color designation data TSD that specifies the tone corresponding to the turned on switch is generated. This timbre specification data TSD is supplied to the keyboard performance sound formation circuit 12 and the automatic performance sound formation circuit 22 and used to set the timbre characteristics corresponding to the designated timbre, and is also supplied to the start address memory 20 and used to set the timbre characteristics corresponding to the designated timbre. It is converted into the first address data THA. When the switch TR3 is in the off state, the selector 24 selects the first address data THA from the memory 20 and supplies it to the memory 18 as the first address data HA. As a result, the performance data of the song having the start address indicated by the start address data HA (that is, the song that matches the selected tone color) can be read from the memory 18.

The start address memory 26 is, for example, a ROM, and stores the start address in the memory 18 for each selectable rhythm for the @performance data of a song that matches the rhythm.

When a desired one of the rhythm selection switches R3(1) to R3(m) is turned on, rhythm designation data R5D that designates the rhythm corresponding to the turned-on switch is generated.

This rhythm designation data R5D is stored in the autorhythm device 28.
The data is supplied to the start address memory 2B and used to select a rhythm pattern corresponding to the designated rhythm, and is also supplied to the start address memory 2B and converted into the corresponding start address data RHA. When switch TR3 is on, selector 2
4 selects the head address data RHA from the memory 2B and supplies it to the memory 18 as the head address data HA. As a result, the song that has the start address indicated by the start address data HA (that is, the song that matches the selected rhythm)
The performance data can be read from the memory 18.

Now, with switch TR3 turned off, switch TS
Assuming that the switch STS is turned on after turning on a desired one of (1) to TS (n), the switch STS
The on signal ST is differentiated by the differentiating circuit 3° and converted into a differentiated output pulse DST. This output pulse DST
is supplied to the read control circuit 32 to start the read operation.

That is, the output pulse DST causes the address counter 36 to be reset via the OR gate 34, while the R-S
Set the flip-flop 38. The output Q=“°0” of the flip-flop 38 maintains the counter 36 in the reset release state via the OR gate 36. Further, the output Q="l" of the flip-flop 38 is supplied to the autorhythm device 28 as a rhythm enable signal REN, and starts the rhythm sound signal generation operation.

The autorhythm device 2 has a pattern memory that stores rhythm patterns corresponding to selectable disco, waltz, and ballad rhythms, and from this pattern memory corresponds to a designated rhythm according to rhythm designation data R3D. By selecting a rhythm pattern to be played and reading out the selected rhythm pattern based on the tempo clock signal TCL from the tempo clock generator 40, rhythm sound sources such as a bass drum, snare drum, maracas, etc. are selectively driven. It is designed to generate a rhythm sound signal. The rhythm sound signal generated by the autorhythm device 2 is supplied to the speaker 16 via the output amplifier 14, and is emitted as a rhythm sound.

On the other hand, the output pulse DST is passed through the OR gate 42 to R
-S flip-flop 44 is set, and the output Q="1" of this flip-flop causes AND gate 46 to conduct. Therefore, the system clock signal SYC from the system clock generation circuit 48 is supplied to the counter 36 via the AND gate 46.

When the counter 36 counts a clock with a clock signal SYC, pitch data representing the pitch of the first note of the performance data of the song that matches the selected tone is extracted from the memory 18 in response to the address signal ADS corresponding to the count state. is read out. The read data RD from the memory 18 is
Pitch mark detection circuit 50, latch circuit 52, note length mark detection circuit 5B, latch circuit 58, end code detection circuit 8
It is designed to be supplied to 8th grade.

When the pitch mark detection circuit 50 detects a pitch mark included in the read pitch data, it generates a pitch mark detection signal PM, and in response, the pitch data is latched into the latch circuit 52. Ru.

The automatic performance sound forming circuit 22 has a pitch corresponding to the pitch data FD from the latch circuit 52 and has a pitch corresponding to the tone designation data T.
A musical tone signal having a tone indicated by SD is formed and transmitted.

Therefore, the musical tone corresponding to the first note is emitted from the speaker 16.

When counter 36 counts the next clock of system clock signal SYC, note length data representing the note length of the first note is read from memory 18.

When the note length mark detection circuit 56 detects a note length mark included in the read note length data, it generates a note length mark detection signal LM, and in response, the note length data is latched in the latch circuit 58. Ru. The note length mark detection signal LM is OR
Since the flip-flop 44 is reset via the gate 60, the AND gate 46 becomes non-conductive and the read operation is temporarily stopped. In addition, the note length mark detection signal LM
causes the tempo clock counter 62 to be reset. After this reset, the counter 62 receives the tempo clock signal T.
Count CL.

The comparison circuit 64 receives the note length data LD from the latch circuit from the 5th day.
and count data CD from the counter 82, and when the two values match (at the timing corresponding to the end of the note length), a match output EQ is generated. This matching output E
Q is differentiated at the rising edge by a differentiating circuit 68 and converted into a differentiated output pulse DEQ.

This output pulse DEQ causes the flip-flop 44 to be set via the OR gate 42, so that the AND gate 4
6 becomes conductive, pitch data and note length data for the second note are sequentially read out from the memory 18 in the same manner as described above, and a musical tone corresponding to the second note is generated from the speaker 16.

Thereafter, by repeating the reading operation as described above, the automatic performance of a piece of music that matches the selected tone color progresses. When the end code data as the last data of the performance data is read from the memory 18, the end code detection circuit 68 generates the end code detection signal END. This end code detection signal END causes the flip-flop 38 to be reset via the OR gate 70. Therefore, the counter 36 enters a reset state in response to the output Q="l" of the flip-flop 38, and the autorhythm device 28
The rhythm sound signal generation operation is stopped in response to the output Q: "0"' of the flip-flop 38. Further, the output of the OR gate 70=“1” causes the flip-flop 44 to be reset via the OR gate 60. Note that when the switch SPS is turned on during the performance, the flip-flops 38 and 44 are reset in response to the ON signal SP, so the automatic performance and autorhythm are stopped at that point.

What has been described above is the read operation when the switch TR3 is turned off. However, when the switch TR3 is turned on, the memory 26 is used instead of the memory 20, and a song matching the selected rhythm is selected from the memory 18. The same operation as described above is performed except for this point.

Second Practical Example (Fig. 2) Fig. 2 shows the circuit configuration of an electronic musical instrument equipped with an automatic performance device according to a second embodiment of the present invention. The detailed explanation will be omitted by attaching the symbol .

The feature of the second embodiment is that it is possible to continuously automatically play a plurality of songs for each selectable tone color (or rhythm).

In the start address generation circuit 80, the start address memory 2OA stores the count value of the address counter 84 (value of address data AD) of 0.1, 2.3, respectively, for each designated gold color, as shown in FIG. Four corresponding storage areas are provided. In Figure 3, THAI
NTHA3THA5 and THA9 are 1st to 3rd, respectively.
．． This is the start address data of the 5.9 song, and EM is the end mark data.

Now, when the switch TS (1) corresponding to, for example, a piano tone is turned on while the switch TR5 is turned off, and the switch STS is turned on, the ON signal ST causes the counter 84 to be reset via the OR gate 82. Therefore, the first address THA2 corresponding to the AD value O is read out from the memory 20A among the first addresses for the three songs that match the piano tone, and is sent to the memory 20A via the selector 24.
8. Further, the output pulse DST generated from the differentiating circuit 30 in response to the ON signal ST is output from the OR gate 7.
While setting the flip-flop 38 through 2,
OR gate 7? and 42 through flip-flop 44
is set, and the address counter 3s (Fig. m1) is reset via the OR gates 72 and 34. The read control circuit 32A has the first
It has the same configuration as the readout control circuit 32 shown in the figure. Therefore, the performance data of the second music piece is read out from the memory 18, and the automatic performance of the second music piece is performed based on the read data.

When the automatic performance of the second music piece ends, an end code detection signal END is generated. This signal END causes flip-flop 38 to be reset via OR gate 70, while flip-flop 44 is reset via OR gates 70 and 60, and the value of counter 84 is increased by one. Therefore, the start address T HA 5 is read from the memory 2OA and supplied to the memory 18 via the selector 24.

At this time, the change detection circuit 86 detects the output T of the memory 20A.
A detection output is generated in response to a change in the value of HA, and this detection output is supplied to the delay circuit 82 via the AND gate 88 which is rendered conductive by the output of the inverter 90=“1”. The delay circuit 92 delays the system clock signal SYC from the read control circuit 32A by one clock, and its delayed output DA is supplied to the OR gate 72 and acts in the same manner as the output pulse DST described above. . Therefore, the performance data of the fifth song is read out from the memory 18,
The fifth song is automatically played based on the performance data.

After this, automatic performance of the ninth song is performed in the same manner as described above. Then, at the end of the performance of the 9th song, the memory 2OA
When the end mark data EM is read from the end mark detection circuit 94, the end mark detection circuit 94 generates an end mark detection signal.

This end mark detection signal makes AND gate 88 non-conductive via inverter 90, and is supplied to delay circuit 9G, which functions similarly to delay circuit 92 described above. The delayed output HMA from delay circuit S6 causes counter 84 to be reset via OR gate 82, while OR gate 7
0, and acts in the same way as the end code signal END described above. Therefore, the automatic performance of songs 2, 5, and 9 that match the piano tone is completed. In addition, during automatic play, switch S
When PS is turned on, the on signal SP is sent to the OR gate 70.
Since it acts in the same way as the end code signal END, the automatic performance stops at that point.

The above is the operation when the switch TR3 is turned off. However, when the switch TR5 is turned on, the start address generation circuit 100 having the same configuration as the start address generation circuit 80 is used instead of the start address generation circuit 80. This makes it possible to continuously play multiple songs that match the selected rhythm.

In the start address generation circuit 100, the start address memory 2EIA stores 4 addresses corresponding to AD values O11, 2, and 3 for each specified rhythm, as shown in FIG.
Two storage areas are provided. In Figure 4, RH
A2 to RHA6, RHAa, and RHAq are the second
~6.8.9 The signals ST, END, and SYC supplied to the circuit 100 act in the same manner as described above for the circuit 80, and EM is the end mark data. are signals DB similar to signals DA and HMA described above for circuit 80, respectively.
, EMB are generated in the same manner. The signals DE and EMB act on the read control circuit 32A in the same way as the signals DA and HMA, respectively.
For example, if a disco rhythm is selected as the output RHA, the first addresses RHA3 and RHA6 are sequentially sent out, and accordingly, the third and sixth songs are automatically played in sequence.

Third Embodiment (FIG. 5) FIG. 5 shows the circuit configuration of an electronic musical instrument equipped with an automatic performance device according to a third embodiment of the present invention, and shows the same parts as FIGS. 1 and 2. are given the same reference numerals and detailed explanations will be omitted.

In response, R-S flip-flop 10B is set. The output Q="1" of the flip-flop 10B is sent to the selector 88 of the head address generation circuit 80A in the memory 20.
It is supplied as a signal TMS instructing the selection of A. Therefore, in this case, using the memory 2OA, it is possible to continuously perform a plurality of pieces of music matching the selected tone color in the same manner as described in FIG. Then, the delay output H from the delay circuit 96
When MA is generated or switch SPS is turned on, OR gate 114 generates an output =II I 11 and flip-flop 106 is reset accordingly.

On the other hand, when only the switch STS is turned on, the selector 98 is in a state of selecting the first address memory 20B. In the memory 20B, if the number of songs stored in the memory 18 is N, then the AD value of the counter 84 is 0, 1.2...(N-1).
), the start address data of the 1st, 2nd, 3rd...N songs are stored, respectively. For this reason, memory 20
As the output THA2 of B, after the start address data of the first song is sent out when the switch STS is turned on, the start address data of the next song is sent out every time one song is played, and all the songs in the memory 18 are sent out. can be played sequentially.

R-S flip-flop RF (1) to R5(m) are
These are set-priority flip-flops provided corresponding to switches R3(1) to RS(m), respectively.
When any of R3(1) to R3(m) is turned on, the flip-flop corresponding to the turned-on switch is set, and the remaining flip-flops are set to R3(1) to R3.
It is designed to be reset by the output of the OR gate 108 which inputs the state signal (m). From flip-flops RF(1) to RF(m), rhythm designation data R5 designates the rhythm corresponding to the turned-on switch.
D is taken out.

When the switch STS is turned on while any of the switches R3(1) to RS(m) are on or at the same time, the A

Therefore, in this case, the memory 28A can be used to continuously perform a plurality of pieces of music matching the selected rhythm in the same manner as described in FIG. Then, the delay output EM from the delay circuit corresponding to the delay circuit 96 is
When B is generated or switch SPS is turned on, OR gate 114 generates an output="1" and flip-flop 112 is reset accordingly.
