DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance device.

[0002]

2. Description of the Related Art In general, the melody of a piece of music may be slightly changed due to ad lib or the like, but the chord progression is basically determined from the beginning and is not changed. A player performs by instructing a tempo, intensity (volume), timbre, and the like. In particular, in a general electronic keyboard instrument, various performances can be performed by mainly controlling the tempo and the intensity, and the performance is enjoyable.

[0003]

It is difficult for a person who is not familiar with keyboard instruments to memorize the chord progression for one song and play a melody or chord in accordance with the chord.

In a semi-automatic performance device, the chord of the accompaniment advances automatically, and the melody advances by the performance operation of the player. At this time, the strength of the accompaniment is determined according to the strength of the melody played by the player. However, if the melody performance is not performed at the beat at which the chord changes, the accompaniment intensity cannot be determined, so that the accompaniment is performed with a preset default accompaniment intensity. For this reason, the accompaniment part and the melody part may have an unnatural volume balance.

In the conventional automatic performance, the accompaniment intensity and tempo are set in advance and cannot be changed by the player during the performance.

It is an object of the present invention to provide a performance device capable of changing a pitch designated by a performance operator in accordance with a chord. It is another object of the present invention to provide a performance device capable of instructing chord progression timing by a performance control operator. Still another object of the present invention is to provide a performance device capable of instructing the velocity of automatic performance data by a performance control operator. Still another object of the present invention is to provide a performance device capable of instructing a tempo of an automatic performance by a performance control operator.

[0012]

(First Embodiment) FIG. 1 shows the configuration of an electronic musical instrument (playing apparatus) according to a first embodiment of the present invention, and FIG. 2 is a flowchart showing the processing thereof.

In step S201, a performance assist mode is set. For example, by pressing a switch on the panel 101, a performance assist mode is set.

In step S202, the operator selects a performance control operator from predetermined operators. For example, using the panel 101, one of a keyboard (first key to 88th key), a damper pedal, and a soft pedal is selected as a performance control operator for controlling chord progression timing. Since the performance control operator destroys the function of the original operator, it is desirable to select an operator that is not used as much as possible. For example, a soft pedal, a first key, an eighth key
Eight keys are preferred. The operator allocating unit 102 includes a panel 101
One performance control operator 103 is assigned from the operators according to the above operation.

In step S203, the chord (chord) of the music to be played by the user is entered on the panel 101 or the keyboard 1
08 and sequentially input them, and store them in the chord progression storage unit 105. Note that chord progression data that has already been input may be selected and stored in the chord progression storage unit 105.

In step S204, it is checked whether the automatic performance start switch has been pressed. If pressed, the process proceeds to step S205.

In step S205, the code reading unit 1
04 reads the first chord from the chord progression storage section 105 and outputs it to the automatic performance section 106 and the performance data correction section 109. The automatic performance section 106 reads the automatic performance data from the automatic performance data storage section 107 and outputs the automatic performance data corresponding to the code to the sound source section 110. Sound source section 11
0 outputs a tone signal corresponding to the automatic performance data to the sound system 111 for sound generation. Thereby, an automatic performance is performed. The automatic performance data storage unit 107
Stores automatic performance data other than chords.

In step S206, when the user operates the keyboard (performance operator) 108, key-on information is generated. The performance data correction unit 109 includes the code reading unit 10
The pitch in the key-on information designated by the keyboard 108 is corrected in accordance with the code read out by step 4. That is, when the pitch of a key struck on the keyboard 108 does not match the chord, the pitch of the key is corrected to a pitch that matches the chord and output to the tone generator 110. The tone generator 110 includes a pitch output from the performance data corrector 109 and a keyboard 108.
A tone signal is generated in accordance with the velocity or the like in the key-on information, and output to the sound system 111 for sound generation.

In step S207, the performance control operator 1
When 03 is operated, the chord reading unit 104 reads the next chord from the chord progression storage unit 105 and outputs the chord to the automatic performance unit 106 and the performance data correction unit 109. The processing of the automatic performance section 106 and the performance data correction section 109 is the same as described above. Thus, the chord progression timing can be controlled by the operation timing of the performance control operator 103.

In step S208, it is checked whether or not automatic performance end data has been read from the automatic performance data storage unit 107. If it is not the end data, the process returns to step S206, and the above processing is repeated. If it is the end data, the process ends. Note that the automatic performance can be terminated at any time by pressing the stop switch during the automatic performance.

According to this embodiment, the chord progression timing can be controlled in real time by operating the performance control operator. Also, the chord progression storage unit 1
By storing the chord progression in 05, the user does not need to memorize the chord progression, and the chord progression is not mistaken. Further, since the pitch indicated by the performance operation on the keyboard is corrected so as to be in harmony with the chord, the melody performance or the ad-lib performance can be performed without producing a dissonant sound.

(Second Embodiment) FIG. 3 shows the configuration of an electronic musical instrument (playing apparatus) according to a second embodiment of the present invention, and FIG. 4 is a flowchart showing the processing.

In step S401, a performance assist mode is set. For example, by pressing a switch on the panel 301, a performance assist mode is set.

In step S402, the operator selects a performance control operator from predetermined operators. The performance control operator is an operator for instructing the velocity (strength) of automatic performance and the chord progression timing. For example, using the panel 301, one performance control operator is selected from a keyboard (first key to 88th key), a damper pedal, and a soft pedal. Since the performance control operator destroys the function of the original operator, it is desirable to select an operator that is not used as much as possible. The operator assignment unit 302 assigns one performance control operator 303 from the operators in accordance with an operation on the panel 301.

In step S403, desired automatic performance data is selected. The automatic performance data is music data including tempo, chord progression, velocity (strength), melody data and the like of the automatic performance.

In step S404, it is checked whether the automatic performance start switch has been pressed. If pressed, the process proceeds to step S405.

In step S405, the performance control operator 3
03 is operated, the automatic performance data correction unit 306
The automatic performance data is read from the automatic performance data storage unit 308, the velocity of the automatic performance data is corrected, and output to the automatic performance unit 307. More specifically, the automatic performance data correction unit 306 detects the velocity of the performance control operator (for example, the first key) 303 and corrects the velocity of the automatic performance data to the detected velocity. When the velocity is instructed by the performance control operator 303, the automatic performance data correction unit 306 outputs the automatic performance data storage unit 30 until the velocity is next instructed by the performance control operator 303.
Automatic performance data is sequentially read out from step 8 and corrected to the designated velocity. The automatic performance data storage unit 30
8 stores automatic performance data other than chords.

When the performance control operator 303 is operated, the chord reading section 304 sets the chord progression storage section 305
And outputs it to the automatic performance unit 307.
The chord progression storage unit 305 stores chord progressions of music pieces in order. The automatic performance section 307 receives the automatic performance data from the automatic performance data correction section 306 and
The automatic performance data corresponding to the code read by the section 04 is output to the tone generator 310. The tone generator 310 outputs a tone signal corresponding to the automatic performance data to the sound system 311 for sound generation. Thereby, an automatic performance is performed. As described above, the performance control operator 303 can instruct the velocity and chord progression timing of the automatic performance data.

When the user strikes the keyboard (performance operator) 309, key-on information (including pitch information and velocity information) is generated. The tone generator 310 outputs a tone signal corresponding to the key-on information to the sound system 311 to generate sound. Thus, the melody part is played manually.

In step S406, it is checked whether or not automatic performance end data has been read from the automatic performance data storage unit 308. If it is not the end data, the process returns to step S405, and the above processing is repeated. If it is the end data, the process ends. Note that the automatic performance can be terminated at any time by pressing the stop switch during the automatic performance.

According to the present embodiment, the velocity (strength) of automatic performance data and the chord progression timing can be controlled in real time by operating the performance control operator. Also, since the velocity of the automatic performance data can be instructed by the performance control operator, the automatic performance can be performed at an appropriate velocity even without a note in the melody part. The player can arbitrarily change the balance between the velocity of the melody part and the velocity of the accompaniment part of the automatic performance.

(Third Embodiment) FIG. 5 shows the configuration of an electronic musical instrument (playing apparatus) according to a third embodiment of the present invention, and FIG. 6 is a flowchart showing the processing.

In step S601, a performance assist mode is set. For example, by pressing a switch on the panel 501, a performance assist mode is set.

In step S602, the operator selects first and second performance control operators from predetermined operators. The first performance control operator is an operator for instructing the velocity of automatic performance data and the chord progression timing. The second performance control operator is an operator for instructing the tempo of the automatic performance. For example, using the panel 501, a keyboard (1st to 88th keys), a damper pedal,
First and second performance control operators are selected from the soft pedals. Since the first and second performance control operators kill the original functions of the operators, it is desirable to select operators that are not used as much as possible. Operator assignment section 50
Reference numeral 2 assigns first and second performance control operators 503a and 503b from among the operators according to the operation on the panel 501.

In step S 603, the chords of the music to be played by the user are sequentially input on the panel 501 or the keyboard 509, and stored in the chord progression storage unit 505. Select the chord progression data that has already been entered,
It may be stored in the chord progression storage unit 505.

In step S604, automatic performance is set. For example, a style, a tempo, and the like are set. You may make it set automatically.

In step S605, it is checked whether the automatic performance start switch has been pressed. If pressed, the process proceeds to step S606.

In step S606, the code reading unit 5
04 reads the first chord from the chord progression storage section 505 and outputs it to the automatic performance section 508 and the performance data correction section 510. The automatic performance section 508 reads the automatic performance data from the automatic performance data storage section 506 via the automatic performance data correction section 507, and outputs the automatic performance data corresponding to the code to the sound source section 511. The sound source unit 511 outputs a tone signal corresponding to the automatic performance data to the sound system 512 to generate sound. Thereby, an automatic performance is performed. The automatic performance data storage unit 506 stores automatic performance data other than chords.

In step S607, when the user operates the keyboard (performance operator) 509, key-on information is generated. The performance data correction unit 510 includes the chord reading unit 50
The pitch in the key-on information specified by the keyboard 509 is corrected in accordance with the code read in step 4. That is, when the pitch of a key struck on the keyboard 509 does not match the chord, the pitch of the key is corrected to a pitch that matches the chord, and output to the tone generator 511. The tone generator 511 generates a tone signal in accordance with the pitch, velocity, and the like output from the performance data corrector 510, and outputs the tone signal to the sound system 512 for sound generation.

In step S608, when the first performance control operator 503a is operated, the code reading unit 504 is operated.
Reads the next chord from chord progression storage section 505 and outputs it to automatic performance section 508 and performance data correction section 510. Automatic performance section 508 and performance data correction section 510
Is the same as above. Thus, the chord progression timing can be instructed by operating the first performance control operator 503a.

When the first performance control operator 503a is operated, the automatic performance data correction unit 507 reads out the automatic performance data from the automatic performance data storage unit 506, corrects the velocity of the automatic performance data, and sets the automatic performance data. Performance part 508
Output to Specifically, the automatic performance data correction unit 507
Detects the velocity of the first performance control operator (for example, the first key) 503a and corrects the velocity of the automatic performance data to the detected velocity. When the velocity is instructed by the first performance control operator 503a, the automatic performance data correction unit 507 then inputs the first performance control operator 503.
Until the velocity is designated by 3a, the automatic performance data is sequentially read from the automatic performance data storage unit 506 and corrected to the designated velocity. By operating the first performance control operator 503a, it is possible to instruct not only the chord progression timing but also the velocity of the automatic performance data.

In step S609, if the second performance control operator 503b is continuously operated within a predetermined time (for example, if the soft pedal is continuously depressed within a predetermined time), it is operated first. The tempo is calculated based on the time and the time interval of the next operation, and the tempo of the automatic performance is determined. That is, the automatic performance data correction unit 507 determines the tempo of the automatic performance only when the operation interval of the second performance control operator 503b is within a predetermined time. Automatic performance section 508
Outputs the automatic performance data to the tone generator 511 according to the tempo in the same manner as described above, and automatically performs the performance at the instructed tempo.

In step S610, it is checked whether or not automatic performance end data has been read from the automatic performance data storage unit 506. If it is not the end data, the process returns to step S607, and the above processing is repeated. If it is the end data, the process ends. The automatic performance can be terminated at any time by pressing the stop switch during the automatic performance.

Note that the first performance control operator 503 described above is used.
“a” does not need to be one operator such as the first key, and may be a key range including a plurality of operators such as the first key to the sixteenth key. If the low range of the keyboard (for example, the first key to the sixteenth key) is selected as the first performance control operator 503a, any key can be pressed within the low frequency range, so the first performance control operator 503a Operation becomes easy, and the user can concentrate on the performance. A plurality of controls may be selected as other performance control controls.

The first performance control operator 503a and the second performance control operator 503b may share one common operator. If the operation interval of the common operator is within a predetermined time, the tempo is instructed as the second performance control operator.
, The chord progression timing and velocity are instructed as the performance control operators. The predetermined time is, for example, 70% of one bar and can be determined by the following equation.

(Tempo / 60) × (numerator of time signature / denominator of time signature) × numerator of time signature × 0.7 [sec]

According to the present embodiment, the operation of the first performance control operator indicates the velocity and chord progression timing of the automatic performance data, and the operation of the second performance control operator indicates the tempo of the automatic performance. So you can
The player can easily and freely play music.

This embodiment can be realized by a computer executing a program. Also,
