Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an electronic musical instrument to which an effect control device according to an embodiment of the present invention is applied. This effect control device is included in the electronic musical instrument 100 which is a keyboard instrument as an example. The electronic musical instrument 100 has a main body 30 and a neck 31. The main body portion 30 has a first surface 30a, a second surface (not shown), a third surface 30c, and a fourth surface 30d. The first surface 30a is a keyboard mounting surface (surface) on which the keyboard section KB including a plurality of keys is disposed. The second surface is the back surface (bottom surface), and the

hooks

36 and 37 are provided on the second surface. A strap (not shown) can be placed between the

hooks

36 and 37, and the player usually puts the strap on his shoulder and performs performance such as operating the keyboard KB. Therefore, at the time of use with shoulders, particularly when the scale direction (key arrangement direction) of the keyboard KB is in the left-right direction, the first surface 30a and the keyboard KB face the listener side, the third surface 30c, the fourth The faces 30d face generally downward and upward, respectively. The viewpoint E is an assumed viewpoint position of the player who shoulders the electronic musical instrument 100. The neck portion 31 is extended from the side of the main body 30. The neck portion 31 is provided with various operators including the advance operator 34 and the return operator 35. A display unit 33 composed of liquid crystal or the like is disposed on the fourth surface 30 d of the main body 30. A rotation knob 38 is disposed on the first surface 30a as a rotary operator, and a slide operator 39 is further disposed.

The electronic musical instrument 100 is a musical instrument that simulates singing in response to an operation on a performance operator. Here, the song simulation is to output a voice simulating a human voice by song synthesis. White keys and black keys are arranged in the order of pitches of the keys of the keyboard section KB, and the keys are associated with different pitches. When playing the electronic musical instrument 100, the user presses a desired key on the keyboard KB. The electronic musical instrument 100 detects a key operated by the user, and produces a singing sound of a pitch corresponding to the operated key. The order of the syllables of the singing voice to be pronounced is predetermined.

FIG. 2 is a block diagram of the electronic musical instrument 100. As shown in FIG. The electronic musical instrument 100 includes a central processing unit (CPU) 10, a timer 11, a read only memory (ROM) 12, a random access memory (RAM) 13, a data storage unit 14, a performance control 15, and other operations. Element 16, parameter value setting operator 17, display unit 33, sound source 19, effect circuit 20, sound system 21, communication I / F (Interface), bus 23, detection circuit 18 (detection unit And. The CPU 10 is a central processing unit that controls the entire electronic musical instrument 100. The timer 11 is a module that measures time. The ROM 12 is a non-volatile memory that stores control programs and various data. The RAM 13 is a volatile memory used as a work area of the CPU 10 and various buffers. The display unit 33 is a display module such as a liquid crystal display panel or an organic EL (Electro-Luminescence) panel. The display unit 33 displays the operation state of the electronic musical instrument 100, various setting screens, a message for the user, and the like.

The performance operator 15 is a module that mainly accepts a performance operation that designates a pitch. In the present embodiment, the keyboard portion KB, the advance operator 34, and the return operator 35 are included in the performance operator 15. As an example, when the performance operation element 15 is a keyboard, the performance operation element 15 may be a note on / note off based on sensor on / off corresponding to each key, a key depression strength (speed, velocity), etc. Output performance information. This performance information may be in the form of a MIDI (musical instrument digital interface) message. The other operator 16 is, for example, an operation module such as an operation button or an operation knob for performing settings other than performance, such as settings relating to the electronic musical instrument 100. The parameter value setting operation unit 17 is an operation module such as an operation button or an operation knob that is mainly used to set parameters for the attribute of the singing voice. Examples of this parameter include harmonics, brightness, resonance, and gender factor. The harmony is a parameter for setting the balance of the harmonic component contained in the voice. Brightness is a parameter for setting the tone of the voice and gives a tone change. The resonance is a parameter for setting timbre and strength of singing voice and musical instrument sound. The gender element is a parameter for setting formants, and changes the thickness and texture of the voice in a feminine or male manner. The parameter value setting operator 17 includes a rotation knob 38. The parameter value setting operator 17 is connected to the bus 23 via the detection circuit 18. The detection circuit 18 detects the operation of the parameter value setting operator 17 and sends the detection signal to the CPU 10. The external storage device 3 is, for example, an external device connected to the electronic musical instrument 100, and is, for example, a device that stores audio data. The communication I / F 22 is a communication module that communicates with an external device. The bus 23 transfers data between the units in the electronic musical instrument 100.

The data storage unit 14 stores singing data 14a. The song data 14a includes lyric text data, a phonological information database, and the like. The lyric text data is data describing the lyric, and is data to be sung by the singing part (the sound source 19, the effect circuit 20 and the sound system 21). In the lyric text data, the lyrics of each song are described divided in syllable units. That is, the lyric text data has character information obtained by dividing the lyrics into syllables, and the character information is also information for display corresponding to the syllables. Here, the syllable is a group of sounds output in response to one performance operation. The phonological information database is a database storing speech segment data (syllable information). The voice segment data is data indicating a waveform of voice, and includes, for example, spectrum data of a sample string of the voice segment as waveform data. The speech segment data includes segment pitch data indicating the pitch of the waveform of the speech segment. The lyrics text data and the speech segment data may each be managed by a database.

The sound source 19 is a module having a plurality of tone generation channels. Under the control of the CPU 10, one sound generation channel is assigned to the sound source 19 in accordance with the user's performance. In the case of producing a singing voice, the sound source 19 reads voice segment data corresponding to a performance from the data storage unit 14 in the assigned tone generation channel to generate singing voice data. The effect circuit 20 applies the acoustic effect designated by the parameter value setting operator 17 to the singing voice data generated by the sound source 19. The sound system 21 converts the singing sound data processed by the effect circuit 20 into an analog signal by a digital / analog converter. Then, the sound system 21 amplifies the singing sound converted into the analog signal and outputs it from a speaker or the like.

FIG. 3 is a plan view of the rotation knob 38. As shown in FIG. The rotation knob 38 is configured to be rotatable about the center point G, and has an operation stroke with a position indicated by Min in FIG. 3 as an initial position and a position indicated by Max as a rotation end position. The operation stroke is composed of a plurality of movable ranges R (R1, R2, R3, R4). The player can position the designated position 38a of the rotary knob 38 at an arbitrary position in the operation stroke, and the position of the designated position 38a becomes the operated position. The operation of the rotation knob 38 is detected by the detection circuit 18, and the CPU 10 acquires the operation position of the rotation knob 38 from the detection signal. That is, the CPU 10 acquires the rotational position indicated by the designated position 38 a as the operation position of the rotation knob 38. The non-moving range r0 is a region that can not be the operation position of the rotation knob 38. The immovable range r0 is located on the opposite side of the central point G when viewed from the viewpoint E. As a result, the player who shoulders the electronic musical instrument 100 can rotate the rotation knob 38 within a range in which the indication position 38 a is easy to see.

Different types of effects are assigned to each of the movable ranges R. As an example, "REVERB", "CHORUS", "DISTORTION", and "DELAY" correspond to the movable ranges R1, R2, R3, and R4, respectively. Further, in each of the movable ranges R, the value of each effect is associated with the rotational position. The CPU 10 determines the effect of the type assigned to the movable range R to which the obtained operation position belongs to as the effect to be applied to the sound produced (apply), and further, a value according to the operation position is the value of the effect Determined as (parameter value). Therefore, the CPU 10 plays a role as a determination unit. The CPU 10 executes an effect control process based on the determined effect and the value of the effect in generation and sound generation of a singing sound. In any movable range R, the value of the effect is set to be minimum at the side closer to the initial position, and to be larger as the rotation end position is closer. For example, in the movable range R1, in the process of rotating from the initial position to the rotation end position, the value of the effect of “REVERB” to be applied gradually increases. Then, at the timing when the switching position between the movable range R1 and the movable range R2 is passed, the effect of “REVERB” is reset, and the applied effect is transitioned to “CHORUS”.

By the way, around the rotation knob 38 in the movable range R,

display areas

41, 42, 43, 44 are provided corresponding to the movable ranges R1, R2, R3, R4, respectively. In each writing area, a type name is written as information indicating the type of the corresponding effect, and a bar is written as information indicating the value of the effect. The magnitude of the value of the effect is indicated by the length of the bar. In the example of FIG. 3, the length of the rod is different for each of the rotational positions divided into a plurality of stages. As a result, the player can visually recognize the relationship between the operation position of the rotation knob 38 and the effect type and value.

FIG. 4 is a flowchart showing an example of the flow of processing when a performance is performed by the electronic musical instrument 100. Here, the processing in the case where the user performs the selection of the musical composition and the performance of the selected musical composition will be described. Further, in order to simplify the description, a case where only a single sound is output will be described even if a plurality of keys are simultaneously operated. In this case, only the highest pitch among the pitches of keys operated simultaneously may be processed, or only the lowest pitch may be processed. The processing described below is realized, for example, by the CPU 10 executing a program stored in the ROM 12 or the RAM 13 and functioning as a control unit that controls various components provided in the electronic musical instrument 100.

When the power is turned on, the CPU 10 waits until an operation of selecting a song to be played is received from the user (step S101). Note that if there is no song selection operation even after a certain time has elapsed, the CPU 10 may determine that a song set by default has been selected. When the CPU 10 receives the selection of the song, it reads the lyric text data of the song data 14a of the selected song. Then, the CPU 10 sets the cursor position at the top syllable described in the lyric text data (step S102). Here, the cursor is a virtual index indicating the position of the syllable to be pronounced next. Next, the CPU 10 determines whether note-on has been detected based on the operation of the keyboard section KB (step S103). When the note-on is not detected, the CPU 10 determines whether the note-off is detected (step S107). On the other hand, when note-on is detected, that is, when a new key depression is detected, the CPU 10 stops the output of the sound if the sound is being output (step S104). Next, the CPU 10 executes an output sound generation process for producing a singing sound according to note-on (step S105). Here, the CPU 10 corresponds to an instruction acquisition unit that acquires an instruction of singing based on the performance operation of the performance operator 15.

This output sound generation process is briefly described. First, the CPU 10 reads voice segment data of a syllable corresponding to a cursor position, and outputs a sound of a waveform indicated by the read voice segment data at a pitch corresponding to note-on. Specifically, the CPU 10 obtains the difference between the pitch indicated by the segment pitch data included in the voice segment data and the pitch corresponding to the operated key, and the waveform data is obtained by the frequency corresponding to this difference. The spectral distribution shown is moved in the frequency axis direction. Thus, the electronic musical instrument 100 can output a singing sound at the pitch corresponding to the operated key. Next, the CPU 10 updates the cursor position (read position) (step S106), and advances the process to step S107.

Here, the determination of the cursor position and the sounding of the singing voice according to the processes of steps S105 and S106 will be described using a specific example. First, updating of the cursor position will be described. FIG. 5 is a view showing an example of lyrics text data. In the example of FIG. 5, the lyrics of the five syllables c1 to c5 are described in the lyrics text data. Each character "ha", "ru", "yo", "ko", "i" indicates one Japanese hiragana character and each character corresponds to one syllable. The CPU 10 updates the cursor position in syllable units. For example, when the cursor is located at the syllable c3, the voice segment data corresponding to "Y" is read from the data storage unit 14, and the singing voice of "Y" is pronounced. When the sound generation of "Yo" is completed, the CPU 10 moves the cursor position to the next syllable c4. Thus, the CPU 10 sequentially moves the cursor position to the next syllable in response to the note-on.

Next, the pronunciation of the singing sound will be described. FIG. 6 is a diagram showing an example of the type of speech segment data. The CPU 10 extracts speech segment data corresponding to syllables from the phonological information database in order to pronounce syllables corresponding to the cursor position. There are two types of phonetic segment data: phoneme chain data and stationary partial data. The phoneme chain data is data indicating a speech segment when the pronunciation changes, such as "silence (#) to consonant", "consonant to vowel", "vowel to consonant or vowel (of the next syllable)" . The steady part data is data indicating a speech segment when the pronunciation of the vowel continues. For example, when the cursor position is set to “ha” of syllable c 1, the sound source 19 includes voice chain data “# -h” corresponding to “silence → consonant h”, “consonant h → vowel a The voice chain data “ha” corresponding to “” and the stationary partial data “a” corresponding to “vowel a” are selected. Then, when the performance is started and the key depression is detected, the CPU 10 operates the singing voice based on the voice chain data “# -h”, the voice chain data “ha,” and the steady part data “a”. Output according to the pitch according to, the velocity according to the operation. Thus, the determination of the cursor position and the sounding of the singing sound are performed.

When the note-off is detected in step S107 of FIG. 4, if the sound is being output, the CPU 10 stops the output of the sound (step S108), and the process proceeds to step S109. On the other hand, if note-off is not detected, the CPU 10 advances the process to step S109. In step S109, the CPU 10 acquires the current rotational position indicated by the designated position 38a of the rotation knob 38 as the operation position. The CPU 10 acquires the operation position when the power is turned on, and stores the information in the RAM 13. In step S109, when the newly acquired operation position is different from the operation position stored in the RAM 13, the CPU 10 updates the information of the operation position.

Next, in step S110, the CPU 10 determines whether or not there is a change in the operation position based on whether or not the information on the operation position has been updated in step S109. Then, when there is no change in the operation position, the CPU 10 determines whether or not the performance has ended (step S111). Then, the CPU 10 returns the process to step S103 when the performance has not ended. On the other hand, when the performance is ended, if the sound is being outputted, the CPU 10 stops the output of the sound (step S112), and the processing shown in FIG. 4 is ended. Note that the CPU 10 determines whether the performance has ended, for example, whether the last syllable of the selected song has been pronounced, or whether the operation to end the performance has been performed by the other operating element 16 or the like. It can be determined based on

As a result of the determination in step S110, if there is a change in the operation position, should the CPU 10 change the effect type based on the operation position after the change (after the update) (the operation position finally detected in step S109)? It is determined whether or not it is (step S113). That is, the CPU 10 determines the type assigned to the movable range R to which the changed operation position belongs as the type of the effect to be applied, and the type of the determined effect does not match the current effect type, Determine that the effect type should be changed. If not, the CPU 10 determines that the effect type should not be changed. Then, when the effect type is to be changed, the CPU 10 updates the type of the effect to be applied from the current type to the determined type (step S114), and advances the process to step S115. For example, when the operation position transitions from the movable range R2 to the movable range R3, the CPU 10 updates the type of the effect to be applied from “CHORUS” to “DISTORTION”. On the other hand, when the effect type is not to be changed, the CPU 10 keeps the type of the effect to be applied as it is and advances the process to step S115.

In step S115, the CPU 10 determines the value of the effect based on the changed operation position (the operation position finally detected in step S109). Therefore, the value for the effect after updating is determined when the process proceeds through step S114, and the value for the effect maintained as it is is determined when the process after step S114 is not performed. Thereafter, the CPU 10 executes the effect control process according to the type of the effect to be applied and the value of the effect (step S116). Thereby, the effect corresponding to the operation position and the value thereof are given to the singing sound to be pronounced. Thereafter, the process proceeds to step S111.

According to the present embodiment, the type of the effect to be applied and the value of the effect are determined based on the operation position of the rotation knob 38. The type of effect to be given and the degree of the effect can be set. Therefore, since the type of effect to be applied and the degree of the effect can be switched and controlled by one operation element (rotation knob 38), the number of operation elements can be reduced.

Further, since different types of effects are assigned to each of a plurality of movable ranges R which do not coincide with each other in the operation stroke of the rotation knob 38, the user can easily understand and can easily perform the operation of the effect control. Further, since information indicating the types and values of the effects assigned to the plurality of movable ranges R1 to R4 is described in the display areas 41 to 44 corresponding to each of the plurality of movable ranges R1 to R4, the user can It is possible to visually recognize the effect type and value from the rotational position. The information indicating the effect type is not limited to the name, and may be a specific mark. Moreover, the information which shows the value of an effect is not restricted to a rod-shaped mark, For example, the indication by the combination of an arrow and a large and small character may be sufficient.

In step S110 of FIG. 4, it is determined whether or not the operation position has changed as needed even during the displacement of the rotation knob 38. However, the present invention is not limited to this. For example, the CPU 10 acquires, as the current operation position, the position at which the rotation knob 38 is stopped for more than a predetermined time (0.5 second or the like), and the current operation position changes from the previous position. It may be determined that there has been a change in the operation position when it has been set. In this case, when it is determined that the operation position has changed, the CPU 10 reads out the corresponding type and value and updates them, but does not update them while the rotation knob 38 is displaced.

Hereinafter, a modification of the present invention will be described with reference to FIGS. 7 to 10. FIG. 7 is a schematic view of a part of the rotation knob 38. As shown in FIG. At the switching position of the movable range R, the feeling of switching may be transmitted to the operator. For example, as shown in FIG. 7, the portion integrally rotating with the rotation knob 38 rotates inside the substantially circular hole 45 formed in the main body 30. A projection 38 b is provided on the outer periphery of a portion that rotates integrally with the rotation knob 38. On the other hand, two locking portions 46 are formed adjacent to each other on the inner circumference of the hole 45. In the process of rotating the rotation knob 38, when the protrusion 38b passes over the locking portion 46, a click feeling is generated. The rotational position at which the projection 38 b is located between the two locking portions 46 is designed to correspond to the switching position of the movable range R. The pair of locking portions 46 may be provided at a plurality of locations according to the switching position of the movable range R.

FIG. 8 is a schematic plan view of the rotation knob 38 and the display area. In the example shown in FIG. 3, information indicating the type of effect and the value of the effect is written in advance in the display areas 41 to 44 by printing or the like. However, these pieces of information may be electrically displayed in the display area. The display area is configured by an LED, an LCD or the like. The display area is an

area

41a, 42a, 43a, 44a for displaying the type of effect corresponding to the movable range R1, R2, R3, R4, and an

area

41b, 42b, 43b for displaying the value of the effect. , 44b. The CPU 10 controls the display of the display area. In addition, as illustrated in FIG. 8, it is not essential to provide the immovable range r0.

By the way, although the type of effect is assigned in advance to each of the movable range R, the type of the desired effect may be assignable by an instruction from the user. Furthermore, for each of the movable ranges R, a value according to the rotational position may be set according to an instruction from the user. In order to do this, a setting process may be provided separately from the process shown in FIG. 4 and allocation may be performed in the setting process. The setting state may be stored even when the power is turned off. When allocation is performed according to an instruction from the user, the display content of the display area may be dynamically changed. For example, after the setting process and at the start of the process of FIG. 4, the CPU 10 causes the type of the effect to be applied and the value of the effect to be displayed in the corresponding area of the display area. The length of the displayed bar corresponding to the operation position may correspond to the value of the effect. Thereby, a plurality of desired effects can be assigned to one operator, and the number of operators can be reduced.

The plurality of movable ranges R may not be equally divided, and may have different lengths. Also, the plurality of movable ranges R may be set arbitrarily according to an instruction from the user. In this case, the CPU 10 serves as a setting unit that sets a plurality of movable ranges R in the setting process. Thereby, the movable range R can be set to a desired length, and the usability is improved. In the case of adopting an electrical display area, the display area may be configured such that the boundary of the display section changes in accordance with the set movable range R.

FIG. 9 is a plan view of the slide operator 39. The slide operator 39 moves linearly. The above-described configuration in which the type and value of the effect correspond to the operation position is not limited to the rotary type operation element, and can be applied to various operation elements having operation strokes, and there is no limitation on the movable direction. Therefore, the present invention is also applicable to the slide operation element 39 which slides linearly as shown in FIG. The number of movable ranges R may be plural, and the number is not limited. For example, in the slide operation element 39, different types of effects are assigned to each of the movable ranges R1, R2, and R3. Information indicating the type of the corresponding effect and information indicating the value of the effect are displayed in the display area corresponding to each of the movable ranges R. Also in this configuration, a configuration may be adopted in which information is electrically displayed in the display area. By the way, as shown in FIG. 1, the slide direction of the slide operation element 39 is not parallel to the longitudinal direction of the key, and is inclined so that the side near the fourth surface 30d is near the neck portion 31 side. As a result, the player who shoulders the electronic musical instrument 100 can easily operate it.

In addition, regarding the setting of the value of the effect corresponding to the operation position in the movable range R, it is not essential that the closer to the initial position is the smallest and the closer to the rotation end position, the larger the value. For example, on the contrary, the side closer to the initial position may be the largest, and the closer to the rotation end position, the smaller the position. Alternatively, the value of the effect may be maximum or minimum midway in the movable range R, and may be minimum or maximum at the end position near the initial position and the end position near the rotation end position.

Further, the boundary between adjacent movable ranges R is not limited to a point, and may have a range. FIG. 10 is a diagram showing the relationship between the operation stroke and the effect strength (value of effect) of the manipulator of the modified example. The movable direction of the manipulator is not limited to the rotation direction, and may be a straight line or a curved line. Three types of effects are assigned to the movable ranges R1, R2, and R3 as types of effects, respectively, and these effects are referred to as

effects

47, 48, and 49, respectively. The movable ranges R1 and R2 have overlapping regions, and the movable ranges R2 and R3 also have overlapping regions. In each of the movable ranges R, the value of the corresponding effect increases as the operation stroke advances from the respective initial position, becomes maximum halfway, and becomes the minimum at the respective end positions. In the overlapping region of the movable ranges R1 and R2, two types of

effects

47 and 48 are reflected in the effect control with respective values corresponding to the operation position. In the overlapping region of the movable ranges R2 and R3, two types of

effects

48 and 49 are reflected in the effect control with respective values corresponding to the operation position. As described above, the plurality of movable ranges R may be ranges that do not coincide with each other in the operation stroke, and the movable ranges R may have overlapping regions. In that case, overlapping effects may be applied in the overlapping area.

Note that, contrary to the example shown in FIG. 10, there may be a range which does not belong to either of the adjacent movable ranges R. In that case, in the range which does not belong to either, the effect to apply may become unconfirmed (state without the effect applied).

The rotation knob 38 may be configured to rotate 360 °, or may be configured to rotate infinitely. In the case of an infinite rotation configuration, the same effect may be applied to the same movable range R regardless of the number of rotations. Alternatively, the initial state when the power is turned on may be stored, and different types of effects (for example, at the first rotation and two rotations) may be applied depending on the number of rotations even in the same movable range R.

Note that there may be two or more operators to which the present invention is applied. There is no limitation on the types of effects assigned to the movable range R. From the viewpoint of simplifying the configuration, the effect is determined by the movable range R, but the value of the effect may be a fixed value.

Further, in the present embodiment, Japanese lyrics are exemplified as the lyrics to be sung, but the present invention is not limited to this, and other languages may be used. One letter and one syllable do not necessarily correspond. For example, in the case of "da" (da) having a cloud point, two letters "ta" (ta) and "" "correspond to one syllable. For example, when the English lyrics are "september", it becomes three syllables of "sep" "tem" "ber". Although "sep" is one syllable, three characters "s" "e" "p" correspond to one syllable. Each time the user manipulates the performance operation element 15, the CPU 10 sequentially pronounces each syllable at the pitch of the operated key.

In the present invention, the effect given to the singing sound is taken into consideration, but the invention is not limited thereto, and the effect control of the sound generated by the playing operation in the musical instrument or the generation by the sequence data in the sounding device The present invention can also be applied to the effect control of sound. The instruments to which the present invention is applied include not only keyboard instruments but also instruments in which strings are arranged side by side like a guitar. Furthermore, the effect control device of the present invention may be configured as an independent device connectable to output control information regarding the effect to the electronic musical instrument or the sound producing device.

Although the present invention has been described in detail based on its preferred embodiments, the present invention is not limited to these specific embodiments, and various embodiments within the scope of the present invention are also included in the present invention. included.
