Description

  The present invention relates to an operation support device and a keyboard device that perform performance support using light based on performance data.

  2. Description of the Related Art Conventionally, in a keyboard apparatus having a plurality of keys, there is known an operation support apparatus that performs performance guide (performance support) using light by causing a key or a portion corresponding to the key to emit light. There is also known an apparatus that notifies not only the key to be pressed this time but also the key to be pressed after this time. For example, in the apparatus of Patent Document 1, light emitters corresponding to each key are arranged vertically, and light emission corresponding to each key to be pressed gradually moves downward as the performance progresses. According to this, the player can grasp the order and timing of the keys to be pressed from now on by watching the light emission descending.

JP 2001-343888 A

  However, particularly when the light emission starts to drop, the light emission position and the key position are separated from each other. Therefore, it is difficult to visually recognize the correspondence, and it is not easy to specify the key to be pressed. In particular, if the number of light emissions that move at the same time increases, the amount of information to be visually recognized increases too much, and the concentration of concentration on the light emitter becomes too large, distracting attention. In particular, the sensation of bright light emission moving one after another gives the player a stronger pressure than expected, which may be a pain for beginners to enjoy performance practice. It should be noted that it is desirable to avoid that it is difficult to distinguish between a continuous shot and a long tone in the case of a continuous shot in which the same key is pressed continuously.

  The present invention has been made to solve the above-described problems of the prior art, and an object thereof is to promote preparation for pressing and pressing without excessively concentrating on the moving light.

(5), and the control means causes the fixed display unit corresponding to the moving display unit in which the moving light is being displayed to emit light in the first mode, and when the sound generation start timing is reached, The light emission mode of the fixed display unit is switched to a second mode different from the first mode.

  In order to achieve the above object, a keyboard device according to claim 9 of the present invention includes a keyboard having a plurality of keys, a fixed display portion provided corresponding to each key of the keyboard, and each of the fixed display portions. Corresponding movement display units, and control means for displaying, based on the performance data, the movement light corresponding to the notes before the start of sound generation is displayed on the corresponding movement display unit while moving according to the progress of the performance. And the control means causes the fixed display unit corresponding to the moving display unit in which the moving light is being displayed to emit light in the first mode, and when the sound generation start timing comes, the light emitting mode of the fixed display unit Is switched to a second mode different from the first mode.

  In addition, the code | symbol in the said parenthesis is an illustration.

  According to the first and ninth aspects of the present invention, preparation for pressing and pressing can be promoted without concentrating too much attention only on the moving light.

  According to the second aspect, it is possible to visually notify the pressing duration period in advance. According to claim 3, it is possible to easily predict the pressing start timing. In addition, in the keyboard device, it is possible to easily distinguish between continuous shots and long tones.

(A)) of the guide mode process in a modification, and a typical side view (figure (b)) of the keyboard apparatus of a modification.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view of a keyboard apparatus to which an operation support apparatus according to an embodiment of the present invention is applied. The keyboard device 20 is configured as a keyboard instrument, and has a keyboard KB composed of a plurality of white keys and black keys. The keyboard device 20 may be configured as a keyboard device that does not have a sound generation function mainly for performance input.

  Although details will be described later, the keyboard device 20 is also used as a performance support device that performs performance support by light based on performance data. For performance support (performance guide) for notifying keys to be pressed by light, a fixed display portion 21 is provided on the upper surface of the keyboard device 20 behind the keyboard KB (the player side is the front side). A moving display unit 22 is further provided behind the fixed display unit 21. In FIG. 1, the detailed configuration of the movement display unit 22 and the fixed display unit 21 is mainly illustrated and described for the key corresponding to the highest tone, but the movement display unit 22 and the fixed display unit corresponding to other keys are illustrated. 21 also has the same configuration. The fixed display unit 21 is provided corresponding to each key of the keyboard KB, and has one light emitting unit 23 each. The light emitting units 23 are arranged in a line in the key arrangement direction (left-right direction). The movement display unit 22 corresponds to each key, and thus is provided corresponding to each of the fixed display units 21. Each movement display unit 22 includes a plurality (for example, nine) of light emitting units 24 arranged in a line in the front-rear direction. The light emitting unit 23 is composed of, for example, a multicolor LED. The light emitting unit 24 is configured by a single color (for example, green) single color LED.

  FIG. 2 is a block diagram showing the overall configuration of the keyboard device 20. The CPU 5 includes a detection circuit 3, a detection circuit 4, a ROM 6, a RAM 7, a timer 8, a display unit 9, a storage device 10, various I / Fs (interfaces) 11, a sound source circuit 13, and an effect circuit 14 via a bus 16. Connected. The performance operator 1 includes each key of the keyboard KB described above. The detection circuit 3 detects the operation state of the performance operator 1, and the detection circuit 4 detects the operation state of the setting operator 2.

  The display unit 9 is composed of an LCD or the like and displays various information. A timer 8 is connected to the CPU 5. A sound system 15 is connected to the sound source circuit 13 via an effect circuit 14. The various I / Fs 11 include a MIDI (Musical Instrument Digital Interface) I / F and a communication I / F. The CPU 5 controls the entire apparatus. The ROM 6 stores a control program executed by the CPU 5, various table data, and the like. The RAM 7 temporarily stores various input information, various flags, buffer data, calculation results, and the like. The storage device 10 is, for example, a nonvolatile memory, and stores the control program, various music data, various data, and the like. The tone generator circuit 13 converts the performance data input from the performance operator 1 or preset performance data into a musical sound signal. The effect circuit 14 gives various effects to the musical sound signal input from the sound source circuit 13, and the sound system 15 including a DAC (Digital-to-Analog Converter), an amplifier, a speaker, and the like is input from the effect circuit 14. Converts musical sound signals etc. to sound. Based on the detection result of the detection circuit 3, the CPU 5 controls the sound source circuit 13 and the effect circuit 14 to generate sound from the sound system 15.

  In the present embodiment, it is possible to set a guide mode for performing a performance guide using light. In the guide mode, performance guidance is performed based on the automatic performance data. The performance data used is, for example, MIDI data. In the performance data, the sound generation / mute timing is defined for each pitch, and information defining the hand (left and right) to be played is defined as fingering information. When the practice song is selected, the CPU 5 reads out performance data of the selected practice song and generates display instruction data for displaying the moving light group M.

  As shown in FIG. 1, in the guide mode, the moving light group M is displayed on the moving display unit 22, and the fixed light S is displayed on the fixed display unit 21. In FIG. 1, five moving light groups Ma, Mb, Mc, Md, and Me are displayed corresponding to the notes before the start of sound generation within a predetermined time. The moving light group M is a display for notifying a key to be pressed after the current time according to the performance data. The display instruction data for the moving light group M defines not only what is actually displayed on the moving display unit 22 by the light emission of the light emitting unit 24 but also light emitting units that are potentially present outside the light emitting unit 24. . Detailed examples of the movement and light emission mode of the moving light group M and the light emission mode of the fixed light S will be described with reference to FIGS.

  One or more moving lights m constituting the moving light group M will be referred to as moving lights m1, m2,. Taking the moving light group Ma as an example, the moving lights m1 to m5 are actually in a display state, but the moving lights m6 and m7 are not displayed as latent lights. In the present embodiment, the CPU 5 moves the moving light m by causing the light emitting section 24 that emits light to move forward step by step. Accordingly, when the light emitting units 24 that emit light are shifted one by one, the entire moving light group M moves by one step. Since the moving light group M advances forward as the performance progresses, the moving light group M appears from the display start position in the movement display unit 22 and disappears after the display end position. The display start position is a rear end portion in the movement display unit 22, and corresponds to the light emitting unit 24 -S at the rear end among the plurality of light emitting units 24. The display end position is the front end portion in the moving display unit 22, and corresponds to the frontmost light emitting unit 24 -E among the plurality of light emitting units 24. The display end position of the moving display unit 22 is adjacent to the fixed display unit 21.

  The length of the moving light group M is determined according to the corresponding note length when expressed in a variable length with respect to the time axis, and also depends on the performance tempo. Therefore, when the performance tempo is set by the user instead of the performance data default, the length of the moving light group M changes accordingly. Further, when the length is fixed with respect to the time axis, the length of the moving light group M is constant, and the speed of the light moving changes according to the performance tempo.

  In the present embodiment, the length of the moving light group M is substantially defined by the total number of light emitting units 24 that are emitting light and the light emitting units that are potentially present. Of the moving light group M, the moving light m1 that is the head corresponds to the sounding start timing, and the moving light m that is the rear end (moving light m7 in terms of the moving light group Ma) corresponds to one light emitting unit 24. Only (one stage) later corresponds to the mute timing. Note that the sound generation start timing and the mute timing defined by the performance data correspond to the key press start timing and the key release timing with respect to the performance operation, respectively. The traveling light group Mc has only one traveling light m1 that is the leading portion of the traveling light m. The moving light group Mc and the moving light group Md have the same key and are in a repetitive relationship.

  Each moving light m disappears at the next stage (movement timing) displayed by the light emitting unit 24-E. For example, the moving light m1 substantially disappears from the moving display unit 22 at the timing when the moving light m1 virtually moves from the position of the light emitting unit 24-E to the position of the light emitting unit 23 at the sounding start timing. With respect to the emission luminance, in each moving light group M, the leading moving light m1 is displayed with a higher luminance than the other moving lights m. The emission color is the same color (for example, green) for all the moving lights m.

  On the other hand, in the fixed display unit 21, the fixed light S is displayed by the light emitting unit 23 emitting light. For each key, when a part of the moving light group M is displayed on the moving display unit 22, the corresponding fixed display unit 21 also starts to emit light and the fixed light S is displayed. In the example shown in FIG. 1, at least a part of each of the moving light groups Ma, Mb, Mc, and Me is in a display state, so that the fixed lights Sa, Sb, Sc, and Se are displayed correspondingly. Since the moving light group Md corresponds to the same key as the moving light group Mc, the fixed light Sc is displayed as corresponding to the moving light group Mc at the time shown in FIG.

  Regarding the light emission luminance, the fixed light S is initially low luminance (first mode). However, at the same time that the leading moving light m1 displayed by the light emitting unit 24-E disappears in the next stage, the corresponding fixed light S becomes high luminance (second mode). That is, the fixed light S has a low luminance in the key press notification state and a high luminance at the key press start timing. Thereafter, the fixed light S maintains light emission until the silencing timing arrives. That is, the fixed light S disappears at the next stage (silence timing) after the last moving light m displayed on the light emitting unit 24-E disappears. However, if the moving light group M corresponding to the same key is displayed at that stage, the fixed light S does not disappear and the light emission luminance returns to the original low luminance. Therefore, when the moving light group Mc disappears, the fixed light Sc becomes a low-luminance fixed light.

  The light emission colors are distinguished between right and left, for example, fixed light S (fixed light Sa, Sb in FIG. 1) corresponding to the key to be pressed with the left hand is blue, and fixed light S (corresponding to the key to be pressed with the right hand is ( In FIG. 1, the fixed light Sc, Se) is red. As a comparison of the light emission luminance, the relationship is that the moving light m other than the head portion = fixed light S with low luminance <the moving light m1 at the head portion = fixed light S with high luminance. Note that the setting of the light emission luminance is not limited to this example.

  FIGS. 3A to 3C and FIGS. 4A to 4C are transition diagrams of display states of the fixed display unit 21 and the moving display unit 22. Based on the performance data, the CPU 5 displays the moving light group M corresponding to the notes before the start of sound generation on the corresponding moving display unit 22 while moving according to the progress of the performance. The CPU 5 also controls the light emission mode / light extinction of the fixed display unit 21 in accordance with the display and movement of the moving light group M.

  First, FIG. 3A shows a state in which one stage is advanced from the state of FIG. Each of the five moving light groups Ma, Mb, Mc, Md, and Me is moved forward by one light emitting unit 24. The fixed lights Sa, Sb, Sc, Se remain at low brightness. 3 steps from the state of FIG. 3A, the moving light m1 at the head of each of the moving light groups Ma, Mb, Me deviates from the display end position of the moving display unit 22, as shown in FIG. 3B. Therefore, the fixed lights Sa, Sb, and Se are switched to high brightness. When the state proceeds from the state of FIG. 3B by two stages, as shown in FIG. 3C, the moving light m1 of the moving light group Mc deviates from the display end position (the key pressing start timing), so the fixed light Sc Switches to high brightness. At this time, since the last moving light m2 of the moving light group Me has already deviated from the display end position, the fixed light Se is turned off.

  4 steps from the state of FIG. 3C, the last moving light m7 of the moving light group Ma deviates from the display end position and advances one step further as shown in FIG. 4A (key release). Therefore, the fixed light Sa is turned off. On the other hand, the last moving light m7 of the moving light group Mb is also deviated from the display end position. However, since the following moving light group Mf corresponding to the same key as the moving light group Mb appears, the fixed light Sb is low. It switches to the fixed light Sf of brightness | luminance. In addition, the moving light group Mc has already deviated from the display end position, but since the subsequent moving light group Md appears, the fixed light Sc is maintained with high luminance (the name is changed to the fixed light Sd).

  When proceeding one step from the state of FIG. 4 (a), as shown in FIG. 4 (b), the moving light groups Mg and Mh newly appear. Therefore, the corresponding fixed lights Sg and Sh are newly displayed with low luminance. Is displayed. 4 steps from the state of FIG. 4B, as shown in FIG. 4C, the moving light m1 of the moving light group Mf deviates from the display end position (the key pressing start timing), so the fixed light Sf Switches to high brightness.

  Hereinafter, processing for realizing such display control will be described with reference to the flowchart of FIG. When the apparatus is turned on, a main process (not shown) is executed. In this main process, first, the CPU 5 executes initialization. That is, the CPU 5 starts execution of the predetermined program and sets initial values in various registers. Next, the CPU 5 accepts an operation of the setting operator 2 by panel processing and executes device settings. In this panel processing, the CPU 5 sets whether or not to perform the guide mode, selects a song to practice, sets a practice tempo (any value for manual, a value specified by performance data for automatic), selected song The performance data is read out. Next, the CPU 5 executes performance processing. In this performance processing, the CPU 5 generates a performance signal based on the performance data, adds the effect processing set to the generated performance signal, amplifies it, and outputs it. Next, the CPU 5 executes “other processing”. In other processing, the CPU 5 executes real-time performance processing based on the detection result of the detection circuit 3, for example.

  FIG. 5 is a flowchart of the guide mode process. Each process in this flowchart is realized by the CPU 5 reading out the program stored in the storage device 10 or the ROM 6 to the RAM 7 and executing it. This process is repeatedly executed at predetermined time intervals according to the set performance tempo. The execution interval of this process corresponds to one stage of movement of the moving light group M.

  First, in step S <b> 101, the CPU 5 determines whether or not there is moving light m to be newly displayed in the moving display unit 22. This is determined by whether or not there is a note whose sounding start timing comes after the elapse of time T1 (see FIG. 1). The time T1 is a value corresponding to the set performance tempo. If the result of determination in step S101 is that there is no new moving light m to be displayed in the moving display unit 22, the process proceeds to step S104, while there is new moving light m to be displayed in the moving display unit 22. In the case, the process proceeds to step S102. In step S102, the CPU 5 generates display instruction data for displaying the moving light group M having a length corresponding to the note length when the moving light m1 to be displayed is the sounding start timing. At the same time, the CPU 5 displays the moving light m to be displayed at the display start position (light emitting unit 24-S) as the leading moving light m1. The emission luminance of the traveling light m1 is higher than that of the subsequent traveling light m as described above.

  Next, in step S103, the CPU 5 starts to display the fixed light S with low luminance on the fixed display unit 21 corresponding to the displayed moving light m1. Thus, the performer can recognize not only the moving light group M but also the fixed light S closer to the hand and recognize the key to be pressed. Further, the pressing timing can be predicted from the position of the moving light m1 of the moving light group M. Further, as described above, the CPU 5 changes the emission color of the fixed light S depending on the hand to be played. Thereby, the hand which should be used can be confirmed by visual recognition. In step S103, if the fixed light S corresponding to the same key has already been emitted, the light emission mode is maintained as it is. In step S104, the CPU 5 determines whether or not the note corresponding to the moving light group M being displayed has reached the sounding start timing (whether the moving light m1 deviates from the display end position). As a result of the determination, if the note corresponding to the moving light group M being displayed is not at the sounding start timing, the CPU 5 advances the process to step S106, while the note corresponding to the moving light group M being displayed is not detected. If the sounding start timing is reached, the process proceeds to step S105.

  In step S105, the CPU 5 increases the brightness of the fixed light S corresponding to the note that has reached the sounding start timing. Thereby, it is notified that the key pressing start timing has arrived. In step S106, the CPU 5 determines whether the note corresponding to the moving light group M being displayed has reached the mute timing (whether the last moving light m has deviated from the display end position (light emitting unit 24-E) one step before). ) Determine whether or not. As a result of the determination, if the note corresponding to the moving light group M being displayed is not at the mute timing, the CPU 5 advances the process to step S110, while the note corresponding to the moving light group M being displayed is muted. If it is time, the process proceeds to step S107.

  In step S107, the CPU 5 determines whether or not the moving light m1 at the head of the other moving light group M corresponding to the note having the same pitch as the note that is currently muted is being displayed. As a result of the determination, when the moving light m1 at the head of another moving light group M corresponding to the note having the same pitch is not being displayed, the CPU 5 performs the mute timing because the notice display is unnecessary. The fixed light S corresponding to the note is turned off (step S108), and the process proceeds to step S110. On the other hand, when the traveling light m1 at the head of the other traveling light group M corresponding to the note having the same pitch is being displayed, the CPU 5 The light emission luminance of the fixed light S corresponding to the note at the mute timing is returned to the original low luminance (step S109), and the process proceeds to step S110. In step S110, the CPU 5 advances all the moving light groups M that are currently displayed one step forward at a time. At that time, the CPU 5 lowers the emission luminance of the moving light m following the moving light m1 in each moving light group M to be lower than that of the moving light m1. That is, the potential moving light m is displayed with low luminance at the display start position (light emitting unit 24-S). Thereafter, the process of FIG. 5 ends.

  According to the present embodiment, the fixed display unit 21 corresponding to the moving display unit 22 in which the moving light group M is being displayed emits light with low luminance and the fixed light S is displayed. The low-intensity fixed light S can be referred to as a key press notice, and preparation for key press can be promoted without concentrating too much attention only on the moving light group M. In addition, when the sound generation start timing is reached, the light emission mode of the fixed light S is switched to high luminance, so that it is possible to clearly recognize the arrival of the key press start timing and prompt the key press at the sound generation start timing.

  Further, the length of the moving light group M in the traveling direction is made to correspond to the note length, and the moving light group M moves so as to appear after the display start position and disappear after the display end position. Can inform in advance.

  In addition, when the head part (moving light m1) of the moving light group M passes the display end position, the sounding start timing is reached, and the emission luminance of the moving light m1 is higher than that of the other moving light m. It can be easier to predict. In addition, it is possible to easily distinguish between continuous shots and long tones. In particular, since the emission luminance of the moving light m, which is at least the portion other than the head portion in the moving light group M, is lower than the emission luminance of the fixed light S that emits light with high luminance, strong pressure is not given to the player. As a main notice display, attention can be directed to the fixed light S rather than the moving light group M. Further, since the emission of the fixed light S started at the sound generation start timing continues until the mute timing is reached, the arrival of the key release timing can be notified by the fixed display unit 21.

  Moreover, since the fixed display part 21 is arrange | positioned in proximity to the corresponding key, it is easy to visually recognize the key for which the key press is notified. Furthermore, since the display end position of the movement display unit 22 is adjacent to the fixed display unit 21 in the front-rear direction, the correspondence between the movement display unit 22 and the fixed display unit 21 can be easily recognized.

  In the present embodiment, in the guide mode, the guide is advanced according to the performance data without considering the suitability of the performer. However, as shown in FIG. 6A, the guide may be advanced after waiting for the player to press the key. FIG. 6A is an extracted part of a flowchart of the guide mode process in the modification. Specifically, step S201 is inserted between step S105 and step S106 in the flowchart of FIG. In step S201, the CPU 5 waits (stops) until the player properly presses the key corresponding to the note determined to have reached the sounding start timing in step S104. If the performer properly presses the key, the process proceeds to step S106.

  In addition, from the viewpoint of making the correspondence between the moving display unit 22 and the fixed display unit 21 easy to visually recognize, it is not essential that the moving display unit 22 and the fixed display unit 21 face the same direction. For example, FIG. 6B shows a modification. FIG. 6B is a schematic side view of a keyboard device 20 according to a modification. The movement display unit 22 is provided on the upper surface of the rear half of the keyboard device 20, but the fixed display unit 21 is provided in a stepped portion facing the front side in front of the movement display unit 22. Even in this configuration, the correspondence between the moving display unit 22 and the fixed display unit 21 is clear. It should be noted that the present invention is not limited to this modification, and even if the moving display unit 22 and the fixed display unit 21 are not necessarily adjacent to each other and are separated from each other, a geometrical or visual device that recalls the connection between them is provided. You may do it.

  Note that the light emission mode of the fixed light S is different between the notice stage and the sounding start timing, and is low brightness (first form) at the notice stage and high brightness (second form) at the sounding start timing. What is necessary is just to change the aspect of light emission, and it is not restricted to the difference by a brightness | luminance. For example, it may be a difference in emission color or a difference depending on the presence or absence of blinking and the blinking speed. It is desirable that the second mode is more conspicuous than the first mode. The fixed light S may be gradually reduced in luminance toward the key release timing.

  Note that the moving light group M has high brightness only in the leading moving light m1, but the difference in the light emission mode from the other moving light m may be applied in the same manner as the light emission mode of the fixed light S. Good. For the moving light group M, a configuration in which the moving light m1 and the other moving light m are in the same light emission mode is not excluded. Alternatively, the moving light group M may be configured by only the leading moving light m1 regardless of the note length. Further, the configuration in which the moving light m is provided in front of the traveling light m1 in the head portion is not excluded.

  In addition, regarding the change of the emission color depending on the hand (left and right) of the player, the change of the emission mode is not limited to the emission color, and may be a difference depending on the luminance, the presence / absence of blinking, and the blinking speed. Moreover, the structure which changes a light emission aspect with the hand to play is not essential.

  Note that the display of the moving light m and the fixed light S of the moving light group M employs a configuration in which light is emitted from the light emitting units 23 and 24 that are LEDs, but is not limited thereto, and the shape is not limited to a circle. For example, a liquid crystal display may be employed to display the moving light group M and the fixed light S by displaying an appropriate area. In that case, the moving light group M can realize a finer movement.

  The application of the present invention is not limited to performance support in a keyboard device, but can be applied to a device for practicing the operation of pressing an operator. For example, it can be configured as an operation support device that uses a key as a control switch to practice sequence operation.
