Regarding

2. Description of the Related Art JP-A-11-102187 and JP-A-20
In 00-99016, a configuration of an electronic musical instrument having a keyboard performance assisting function that causes a corresponding musical tone in performance data to be pronounced in accordance with the strength of the key depression at each key depression timing and advances the performance of the performance data Is disclosed. With such an electronic musical instrument having a keyboard performance assisting function, it is possible to perform the performance simply by tapping the desired keyboard in accordance with the melody, and anyone can easily enjoy the performance.

Recently, a structure has been studied in which the tempo and strength can be reflected in the reproduction of a song by hitting the keyboard one beat at a time, and according to this, it feels like a conductor. By striking the keyboard, a system will be realized in which songs are played following each other.

The above configuration is premised on tapping the keyboard, and it is difficult to fully enjoy the feeling of the conductor in such keyboard performance. That is, in the key depression operation of the keyboard, the conductor's original pseudo experience of conducting the entire performance by swinging the baton is impossible.

Therefore, in Japanese Unexamined Patent Publication Nos. 6-301381 and 10-55174, it is assumed that the user swings the baton as a conductor. A configuration has been proposed in which the acceleration of the movement of the song is converted into the tempo and strength of the song.

[0006]

However, in the configuration having the keyboard performance assisting function, a predetermined amount of automatic performance data is read at each instruction timing by the user's operation (key depression) to automatically perform the performance. However, it is not a structure that detects the tempo and automatically advances the performance. Therefore, it is not possible to use the above-mentioned conductor performance processing configuration in which the tempo is detected by using the acceleration sensor and the tempo is used for performance progress. That is, in these configurations,
Once the tempo is detected (at the beginning of the song), the performance process automatically progresses from the end of the song to the middle of the song, and the user's command operation is not faithfully reflected. Will end up. Further, in the above-mentioned conductor performance processing configuration, there is a problem that the conductor operation of the user is not reflected until the tempo is fixed, and the performance can proceed only at the tempo that the automatic performance data has.

Further, in the above-mentioned conductor performance processing configuration, since only the strength and weakness of the sound can be controlled in addition to the tempo of the music, a finer nuance is given when the user operates the baton as if he were the conductor. There was a request to detect the commanding operation information transmitted by and to reflect it in the above performance processing.

The present invention was devised in view of the above problems. When the user conducts a command operation, it is possible to transmit detailed nuances of the command, and to prepare at each instruction timing by the command operation. It is intended to provide an electronic musical tone generating apparatus and an automatic performance method capable of automatically performing a performance by reading a predetermined amount of the generated automatic performance data.

[0009]

An electronic musical tone generating apparatus according to the present invention has a structure having an automatic musical performance function for reading a prepared automatic musical performance data by a predetermined amount at each instruction timing by a user's operation. Accordingly, it is basically provided with a detection means for detecting the user's command operation as the operation state, and a control means for executing an arbitrary performance control process according to the level to which the detection value detected by the detection means belongs. It has a feature.

According to the above structure, the prepared automatic performance data is read by a predetermined amount at each instruction timing by the user's command operation to perform the performance, and the command operation of the user is detected by the detecting means. According to the level to which the value belongs, the control means executes arbitrary performance control processing for the performance processing.

The progress of the music is exactly what the conductor conducts, and the tempo of the music should be left to the command operation of the user until the end. Automatic performance is performed at each instruction timing by the user's operation (command). It can be said that the configuration in which the data is read by a predetermined amount and automatically played is suitable for it. In the configuration of the present application, such a (keyboard) performance assisting function is executed instead of the event detection of the baton operation from the key depression event.

Further, if the acceleration sensor provided on the baton is used as the detecting means, the detected value will have a certain range depending on how the baton is swung. Therefore, this detection value range can be assigned to other fine control operation states by the control means.

For example, when the detected value is equal to or larger than a predetermined value, the process of breaking the note data advanced by one beat, that is, the performance stop or mute process can be executed as the performance control process ( Claim 3). This is a motion that stops the song as if the conductor of the orchestra swung the baton at the end of the song (or mutes the song like jean at the end of the song when playing the guitar). This is to imitate (motion). If the performance data exists after the stop (mute) instruction point, the performance may be restarted by detecting the next conducting operation.

If the detected value is equal to or more than a predetermined value,
The process of fading out the note data advanced by 1 beat (the process of gradually decreasing the volume and finally reducing the volume to zero)
Can be executed as performance control processing (claim 4). The fade-out time may be set arbitrarily.

Further, when the detected value is equal to or more than a predetermined value or in an arbitrary detected value range, vibrato processing (processing of modulating frequency), tremolo processing (processing of changing amplitude), tonguing processing (shortening of sound). At least one of a cutting process), a trill process (a process of alternately playing notes of a note data and an adjacent sound above it) and a bend process (a process of raising or lowering a pitch) is executed as a performance control process. (Claim 5). These processes are performed on the current note data, and it is preferable not to perform the process of advancing one beat.

When the detected value is in an arbitrary detected value range, the automatic performance process is executed as a performance control process in which the automatic performance data is read by a predetermined amount (for example, one beat) and played. (Claim 6). This is a process in which the performance is advanced by the command operation of the user, and the process is performed by the command operation (swing the baton). At that time, the volume of the performance may be reflected according to the magnitude of the detected value.

In addition, when the detected value is equal to or less than a predetermined value, it is possible not to perform a specific performance control process by the control means (claim 7). This is a configuration that prevents the performance from being advanced by an unintended action of the user, such as a hand holding a baton.

The structures of claims 8 to 14 are defined by reconsidering the structure of the electronic musical sound generating device as an automatic performance method.

The automatic performance method according to claim 8 corresponds to the structure according to claim 1, and the specific configuration is such that the prepared automatic performance data is instructed by the command operation by the user. It is characterized in that a predetermined amount is read out for each performance and the performance is performed, and a user's conducting operation is detected, and arbitrary performance control processing is executed in response to the level to which the detected value belongs, with respect to the performance processing.

The configuration of the automatic playing method according to claim 9 corresponds to the configuration of claim 2 described above, and a specific configuration thereof is an acceleration sensor provided on a baton for detecting a commanding operation of a user. It is characterized by doing.

The structure of the automatic playing method of claim 10 corresponds to the structure of claim 3 described above.
When the detected value is equal to or more than a predetermined value, performance stop or mute processing is executed as performance control processing.

The structure of the automatic playing method according to claim 11 corresponds to the structure of claim 4 described above.
The fade-out process is executed as the performance control process when the detected value is equal to or more than a predetermined value.

The structure of the automatic playing method according to claim 12 corresponds to the structure of claim 5 described above.
At least one of vibrato processing, tremolo processing, tongue processing, trill processing, and bend processing is executed as performance control processing when the detected value is equal to or more than a predetermined value or in an arbitrary detected value range. Is characterized by.

The structure of the automatic playing method of claim 13 corresponds to the structure of claim 6 described above, and the specific structure thereof is as follows.
When the detected value is in an arbitrary detected value range, the automatic performance process in which the automatic performance data is read by a predetermined amount and played is executed as a performance control process.

The structure of the automatic playing method of claim 14 corresponds to the structure of claim 7, and the specific structure is
When the detected value is less than or equal to a predetermined value, a specific performance control process is not performed.

FIG. 4 is a functional block diagram showing a performance control structure of the electronic piano 100 according to the present invention incorporated in the keyboard performance assisting structure. As shown in the figure, a detection unit 2 that detects a user's conducting operation as the operation state, and a control unit that executes arbitrary performance control processing according to the level to which the detection value detected by the detection unit 2 belongs. 3 and 3. Others In this configuration, the performance data storage unit 20
A music selection section 21, a performance start / stop instruction section 22, a melody / accompaniment performance section 23, and a musical sound generation section 24,
It constitutes the keyboard performance assisting function portion.

In the keyboard performance assist structure, the FDD section 1 is used.
Performance data storage 2 composed of 17 or ROM 113
From the performance data stored in 0, "SONG SELECT (UP / DOWN)" of the panel operation unit 115 is displayed.
When the music selection section 21 composed of a switch (see FIG. 2) selects performance data to be played by the keyboard performance assisting function, the performance data is transferred to the CPU 1
11 is sent to the control unit 3. Similarly, when the "GUIDE" switch (see FIG. 2) of the panel operation unit 115 is pressed and the performance start / stop instruction unit 22 composed of the "CONDUCTOR" switch (see FIG. 2) is pressed, the control unit is controlled. When the instruction to start the performance is issued to 3, the performance data is sent to the melody / accompaniment performance section 23.

During transmission of this data, normally (in the guide mode), the key depression data is sent from the keyboard section 114 to the melody / accompaniment playing section 23, and the control section is synchronized with the key depression timing. 3, the performance data is sent to the melody / accompaniment performance section 23, and in response to this, the musical sound generation section 24 composed of the musical sound generation circuit 118, the D / A conversion circuit 119 and the sound system 120 outputs a musical sound. Will be. That is, at each timing of key depression, the corresponding musical tone in the performance data is sounded at the tempo detected at the time of key depression according to the strength of the key depression,
The performance of the performance data is advanced, and it is possible to perform the performance simply by tapping an arbitrary keyboard in accordance with the melody. Here, of the performance data, the data other than the data relating to the gate time and the velocity is the melody / accompaniment performance section 2
Sent to 3 and gate time and velocity data
It follows key depression data.

In this configuration, by the operation of the panel operation unit 115 (designation of the conductor mode in the guide mode),
Instead of executing such a keyboard performance assisting function by inputting key depression data, the detecting unit 2 attached to the baton 1 is replaced.
The detected value representing the operation state of the baton detected by the above is set so that each performance control process according to the level to which the detected value belongs is executed by the performance assisting function of the control section 3 as described later. It is intended to be used as a trigger signal instead of key depression data.

The detection unit 2 is an acceleration sensor composed of a piezo element or the like, and is configured to convert the value of the acceleration of the motion when the baton 1 is swung into a voltage value and output it. This voltage value is calculated by the A / D conversion circuit 130.
The detected value having a predetermined range is output to the control unit 3. The voltage value actually detected by the acceleration sensor is 0-
It is 5V.

In the control processing by the performance assisting function of the control section 3, for example, as shown in FIG. 5, when expressed by a voltage value [N], detection by erroneous vibration occurs in the range of 0 ≦ N <0.5V. Therefore, no control is performed. That is, this is a control process for preventing the performance from progressing due to an unintended action of the user such as shaking of the hand holding the baton. However, if a musical tone is being pronounced, the pronunciation continuation process is performed.

In the range of 0.5 ≦ N <1V, as a preset process or a process which can be selectively set by the user, the current note data is subjected to a vibrato process (frequency modulation process) and a tremolo process. Processing (processing to change the amplitude), tonguing processing (processing to cut the sound short), trill processing (processing to play the note data sound and the adjacent sound above it alternately and finely), bend processing (processing to raise / lower the chromatic step) ) Any of the processing is applied.
However, processing for advancing one beat is not performed.

In the range of 1≤N <4V, the original performance assisting function (processing for advancing the performance by one beat) for reading and playing the performance data one beat for each trigger signal based on the detection is performed. Based on the following equation 1, the detected value is a value of 1 to 127 (however, when N is 4V, the velocity is 1
It becomes 29 and exceeds 127, so 12
When the number is 7 or more, it is considered as 127),
Used as velocity data of performance data.

[0045]

## EQU1 ## 128 (N-1) / 3 + 1 N: voltage value

In the range of 4≤N≤5V, assuming that the conductor vibrates the baton strongly, the note data advanced by one beat is subjected to break processing (stop of performance: mute). Alternatively, when in the above range, the note data advanced by one beat is faded out. The fade-out time may be set arbitrarily.

In addition, in this configuration, the panel operation unit 115
As shown in FIG. 2, a "METRONOME" switch is provided above, and when this switch is turned on,
The progress of performance data is proceeded by the user's command operation (user's intention), but the metronome sound is produced at a constant tempo independently. This is to assist the user's conducting operation by constructing a structure in which a sound of a certain tempo can be produced independently of the progress of performance data so that the baton can be swung at a certain tempo while not conducting a conducting operation. . However, if you are becoming more commanding, turn off this metronome function. The tempo of the metronome can be changed by clicking "TEMPO (UP
/ DOWN) switch (see FIG. 2).
