Description

  The present invention relates to a drum-type electronic musical instrument capable of generating musical sounds corresponding to a plurality of types of percussion instruments such as drum sets.

  The types of percussion instruments constituting the drum set include, for example, bass drums, hi-hat cymbals, snare drums, bongos, and tam toms. The drums play an important role by cutting the rhythm and leading the music performance, and also having the effect of making the music performance interesting by slightly shifting the timing of hitting a specific drum. Such spice of rhythm (so-called “paste”) largely depends on the skill of the player.

  In general, sticks and the like are used for playing the drums, and the player performs various performances using the extremities of both hands and feet. Which hand (or foot) is used to strike each drum (hereinafter referred to as the “hand”) is not fixed for each drum, especially for drums that are hit by hand. It varies from time to time depending on patterns, ideas, scenes, etc. The player performs a batting performance with a practicing maneuver according to the situation. However, the performance skill that realizes the luck that can bring out the “paste” is not something that can be acquired overnight, but can be gradually mastered by watching live performances or learning from a teacher. is there.

  Therefore, the present applicant has already proposed a performance instruction device (the following Patent Document 1). This device is mainly used for drum lessons, and displays a performance image representing a performance action on a display device that is distant from the hitting surface, and displays a display mode of a musical instrument to be played as the performance progresses. By changing the display mode of the instrument to a different display mode set for each body part to be used in the performance, the instrument instruction information such as the instrument to be operated, the body part (hand) to be operated and the operation timing is displayed. Like to do. Alternatively, the score is displayed, and the body part is displayed on the score for each performance event. For example, for the instrument of the practice part, the body part is associated with each note on the displayed score (for example, above the note). indicate.

JP 2002-116686 A

  However, in the proposed performance instruction device, the maneuver instruction information is only displayed on the screen on the display device, so that the display device is often seen for the next batting, and the batting operation is performed. However, it is not easy to recognize the performance instruction information. In addition, in the method of displaying the body part for each performance event on the score, the body part instruction information corresponds to the note, but is displayed at a position separated from the note. It is not always easy to grasp. Therefore, there is room for improvement in improving visibility and making it easier to practice.

  Further, in the display of the above-mentioned maneuvering instruction information, if it is possible to clearly distinguish and listen to the musical sound of the player's own hit and the musical sound of the performance data, it is possible to practice for the purpose of matching their timings. Further, in addition to the above-described maneuvering instruction information, if it is possible to recognize information on the strength to strike (touch information), it is expected to be more useful for practice.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the prior art, and the object thereof is to provide a drum-type electronic musical instrument that makes it easy to visually recognize handling instruction information and can be used for practice of playing drums. Is to provide.

  In order to achieve the above object, a drum-type electronic musical instrument according to claim 1 of the present invention includes a plurality of hit parts assigned to a percussion instrument type to be hit with either a hand or a leg, a display part, and a drum. Based on the rhythm sequence, a display for recognizing the hitting portion to be hit, the timing of hitting, and the hitting limb indicating which limb hits the hitted portion to be hit by displaying on the display unit A tone signal generator that generates a first tone signal corresponding to the hit portion to be hit based on the control means and the drum rhythm sequence, and generates a second tone signal based on the hit for each of the hit portions. And a musical sound generating means for independently generating musical sounds based on the first and second musical sound signals.

  According to this configuration, based on the drum rhythm sequence, the hit portion to be hit, the timing of hitting, and the hitting limb are recognized by being displayed on the display portion. Recognized. In addition, it is possible to independently listen to the musical sound based on the musical sound data and the musical sound generated by the player's own hitting. In this case, it is more effective if the sound is generated with slightly different timbres, but it is not a necessary condition that the sound is generated with the different sound colors as described above. In this way, the recognition effect is further enhanced by visually recognizing the hit portion, the hit timing, and the hitting limb's maneuvering instruction information. Since it is recognized and discriminated, by practicing with the aim of matching the timing of hitting and / or the hit part (drum type information), the practitioner is fed back with auditory performance assistance and is audiovisual. The educational effect from the viewpoint can be expected. That is, by practicing many times to match the rhythm guide, the timing and touch gradually match, so that the rhythm and touch can be acquired and a subtle “paste” can be acquired. Therefore, it is possible to make it easy to visually recognize the maneuvering instruction information, and to distinguish between the musical sound based on the musical sound data and the musical sound based on the actual hitting, so that it can be used for the practice of playing the drums.

  The display unit includes, for example, a plurality of light emitting units provided corresponding to the hit parts in the vicinity of the hit parts, a screen display capable of displaying a score, or the like.

  Note that a tone data acquisition unit that acquires drum tone data and a sequence generation unit that generates a drum rhythm sequence based on the tone data acquired by the tone data acquisition unit are provided. You may comprise so that the thing produced | generated by the sequence production | generation means may be used. The plurality of hit parts may correspond to each of a plurality of types of musical instruments.

  According to the present invention, it is possible to make it easy to visually recognize the maneuvering instruction information and to make it possible to distinguish and listen to the musical sound by the musical sound data and the musical sound by the actual batting, which can be used for the practice of playing the drums.

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

  FIG. 1 is an external view of an electronic musical instrument according to an embodiment of the present invention. This musical instrument is configured in a drum shape, and a plurality of (four) pad bodies P1 to P4 (struck part), a display 12 (display part) such as a liquid crystal display, a rhythm sound source assignment switch 17, a rhythm selection switch 18, A rhythm start / stop switch 19 and a stereo speaker 4 are provided.

  A percussion instrument type (for example, bass drum, hi-hat cymbal, snare drum, bongo, etc.) can be arbitrarily assigned to each pad body P1 to P4 by the switch 17. Channels CH1 to CH4 are assigned as sound generation channels to the pad bodies P1 to P4, and by hitting each pad body P, drum sounds of timbres corresponding to the pad bodies P are produced on the channels CH1 to CH4. It is generated electronically. On the other hand, the sound generation channels corresponding to the pad bodies P based on the drum rhythm sequence are assigned to channel numbers 5-8. Therefore, in the present embodiment, “8” which is twice the number of the pad bodies P is sufficient for the required number of channels, but a larger number of channels may be provided. In that case, the remaining channels may be used for timbres other than the drum, or may not be generated uniformly. Further, when five or more pad bodies P are provided, the number of channels used for the drum may be ensured by twice as much.

  A plurality of switches 18 exist and are used to select a desired rhythm. The switch 19 is used to instruct execution / non-execution of automatic rhythm performance or the like.

  FIG. 2 is a block diagram showing the overall configuration of the electronic musical instrument.

  The electronic musical instrument includes a pad sensor 3, a panel switch 2, a ROM 6, a RAM 7, a timer 8, a display control circuit 9 (part of display control means), an RSP rhythm memory 10, a storage device 11, and a communication interface (communication I / F). 14, the musical tone forming unit 15 (part of the musical tone generating unit), the sound system 16 (part of the musical tone generating unit), and the light source unit 30 are connected to the CPU 5 (part of the display control unit) via the bus 13. Composed. A timer 8 is connected to the CPU 5, and the display 12 is connected to the display control circuit 9. The communication I / F 14 connects the communication network 101.

  The panel switch 2 includes a plurality of switches (not shown) for inputting various information in addition to the switches 17, 18 and 19. The pad sensor 3 detects the presence / absence of impact and the impact strength (touch) for each of the pad bodies P1 to P4. The CPU 5 controls the entire musical instrument. 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 such as performance data and text data, various flags, buffer data, calculation results, and the like. The timer 8 measures the interrupt time and various times in the timer interrupt process. The display control circuit 9 displays various information such as musical scores on the display 12.

  The RSP rhythm memory 10 stores rhythm data RHD described later. The musical tone forming unit 15 includes an effect circuit (not shown) and converts music data such as rhythm data RHD and automatic performance data into musical tone signals. The sound system 16 includes the speaker 4 and converts a musical sound signal or the like input from the musical sound forming unit 15 into sound. In addition to various data, the storage device 11 can store a control program executed by the CPU 5.

  Each pad body P1-P4 is comprised similarly to what was disclosed by Japanese Patent Application No. 2001-263453 already filed by the present applicant, for example. The pad bodies P1 to P4 are different in size, but are configured in the same manner. Therefore, the configuration of the pad body P2 will be described as an example. As shown in FIG. 1, the pad body P <b> 2 includes a light emitting unit FU (light emitting unit, display unit) and a pad plate 31 to be hit disposed on the case 20.

  FIG. 3 is an exploded perspective view showing the configuration of the pad body P2.

  The pad body P2 is attached to a pad support portion 36 provided integrally on the case 20. The light emitting unit FU includes a light source unit 30 and a light guide 32. The light guide 32 is formed in a substantially annular shape in which a part of the outer periphery is cut out by a space where the light source unit 30 is disposed. The light source unit 30 includes two LEDs (double-head light emitting diodes which are bipole LEDs) (not shown) facing each other. Each LED is installed in the light source units 30L and 30R and provided in the case 20. The hole 30H is attached from the back side. In addition, you may comprise the light source part 30 using two independent commercially available LED instead of a double-head light emitting diode.

  The pad support 36 is provided with four holes 37 and 38, respectively. The pad plate 31 is provided with a sensor support (not shown) formed in a disk shape with a rigid plate-like member, and the pad sensor 3 is attached to the sensor support. The pad plate 31 also has four protrusions 33 protruding downward.

  A tape material (not shown) made of a tape material foam and having a color that easily reflects light is attached to the lower edge of the light guide 32, and the light source unit 30 is attached to the light guide 32. The light emitting unit FU is manufactured. Then, the lower edge of the light emitting unit FU is fitted into the recess 36 a of the pad support 36 and press-fitted so that the light emitting unit FU is press-fitted and held by the pad support 36. Next, the light emitting unit FU is fixed to the pad support portion 36 by screwing the stay 34 of the light guide 32 into the hole 37 of the pad support portion 36 with the screw 35. Thereafter, the pad plate 31 is fixed to the pad support portion 36 by passing the protrusion 33 of the pad body FU through the hole 38 of the pad support portion 36. In this way, the light emitting unit FU is assembled to the pad support portion 36.

  When the light source unit 30 and the light guide 32 are assembled, when the light source unit 30L / R emits light, the light enters the light guide 32 from the L-side and R-side end surfaces 32aL and 32aR. The incident light is efficiently guided along the axial direction of the light guide 32 by the so-called optical fiber light propagation principle. Further, the upper surface of the light guide 32 is formed as a light emitting surface 32c having a slightly rough surface (like ground glass) by a bead blast method or the like. By roughening the light emitting surface 32c, light from the inside of the light guide 32 toward the light emitting surface 32c is likely to be diffusely reflected, and part of the light is totally reflected even with light having a large incident angle with respect to the light emitting surface 32c. It leaks to the outside, and when viewed from the player, the light emitting surface 32c appears to shine.

  As will be described later, the light source unit 30 can cause the light source unit 30L or 30R to emit light independently. When either one of the light source units 30L or 30R emits light, the side close to that of the light guide 32 appears to shine brighter. . For example, if only the light source 30L emits light, the light guide left half 32L appears to shine brighter, and if only the light source 30R emits light, the light guide right half 32R (see FIG. 1) appears to shine brighter. Such right and left divided light emission is used to indicate which hand should hit the corresponding pad body P1 to P4, as will be described later.

  FIG. 4 is a diagram showing the data structure of the rhythm data RHD stored in the RSP rhythm memory 10.

  Rhythm data RHD can be stored for a plurality of songs, each corresponding to one song, such as first rhythm data RHD1, second rhythm data RHD2... RHDn. The header HED stores the start address of each rhythm data RHD. In each rhythm data RHD, channel length data indicating the interval until the next on-event occurrence, and channel data CH indicating the tone generation channel number (hereinafter referred to as “channel CH (RHD)”) based on the rhythm data RHD (this embodiment) In the form of CH = any of 5 to 8) (predetermined channel), rhythm sound source data designating the sound source of the percussion instrument and instructing sound generation, touch data indicating the striking strength, and hitting the pad body P with any hand Pad designation L / R data indicating whether or not to be performed, and END data indicating the end of one song are included. Pr is an address pointer.

  FIG. 5 is a diagram illustrating an example of display on the display 12.

Although details will be described later, the rhythm score as shown in FIG. 5 is displayed on the display 12 for each measure according to the progress of the music by the step S604 of the main process in FIG. Is displayed. Here, the word “rhythm score” is “URL: http://www001.upp.so-net.ne.jp/howtobass/basslesson/4-03.htm”, “URL: http: // www. mext.go.jp/a_menu/shotou/nintei/010102/shogakko/primary/kyokaI/ongaku1.htm "and the like. In the display 12, L on the back
Timing lamps TL1 to TL4 formed by embedding EDs are provided, and each timing lamp TL is sequentially turned on every beat to display the progress of the beat.

  As shown in the figure, the positions of the notes M1 to M4 in the up and down direction on the staff represent the pad body P (type of percussion instrument) to be struck. For example, the pitches F, A, C, E from the bottom correspond to the pad bodies P4, P1, P3, P2 (percussion instrument type assigned to). Further, the positions of the musical notes M1 to M4 in the left-right direction on the staff represent the timing of hitting the percussion instrument. Further, in the vicinity of each note M1 to M4, limb instruction displays H1 to H4 (for example, marks such as “·”) are displayed by LEDs (or LCDs). Each limb instruction display H is displayed on either the left side or the right side of each note M corresponding to the hand (left hand or right hand) to be used for striking for each note M1.

  Note that the limb instruction display mark is not limited to that illustrated, and may be a character display such as “L” or “R”. In addition to the limb instruction display, the pad body P to be struck may be displayed by character display or the like.

  FIG. 6 is a diagram showing a flowchart of the main process in the present embodiment.

  First, various registers and flags such as the RAM 7 are cleared and initial setting is performed (step S601). Next, it is determined whether or not any of the plurality of switches 18 is turned on (there is an on-event) (step S602). If any of the switches 18 is turned on, in steps S603 and S604, the rhythm sound is determined. Performs preparation of pronunciation and rhythm display. That is, the head address of the rhythm data RHD (SEL) determined by the turned on switch 18 is read from the header HED in the RSP rhythm memory 10, and the address pointer Pr (see FIG. 4) is set to the head address (step S603). Next, the first bar portion (including limb instruction displays H1 to H4) of the rhythm data RHD (SEL) is displayed on the display 12 (step S604) (see FIG. 5), and this process is terminated.

  If none of the switches 18 is turned on as a result of the determination in the step S602, it is determined whether or not the switch 19 is turned on (there is an on event) (step S605). As a result of the determination, if the switch 19 is turned on, the RUN flag indicating “1” for permission to execute “automatic rhythm and maneuver instruction processing” to be described later is reversed (step S606), and RUN = 1. It is determined whether or not (step S607). As a result of the determination, if RUN = 1, this is a case where execution of “automatic rhythm and maneuver instruction processing” is permitted this time, so that this processing is immediately terminated, while if RUN = 0, Since execution of the “automatic rhythm and handling instruction process” is prohibited this time, the process proceeds to step S608.

  In step S608, the RUN flag is set to “0” and the address pointer Pr is returned to the head address of the currently selected rhythm data RHD (SEL). Next, in step S609, the display 12 is cleared. Then, the first bar portion of the rhythm data RHD (SEL) is displayed, and this process is terminated.

  If the switch 19 is not turned on as a result of the determination in step S605, it is determined whether or not any of the pad bodies P1 to P4 has been hit (pad-on) (there was an on event) (step S610). As described above, this determination is made on the basis of the presence / absence of hitting and the hitting strength for each of the pad bodies P1 to P4 by the pad sensor 3. If none of the pad bodies P is hit as a result of the determination, other processing (for example, various settings including setting of an auto play (AP) execution instruction described later) is executed (step S613). ), This process is terminated.

  On the other hand, when any one of the pad bodies P1 to P4 is hit, real-time pad processing is performed in subsequent steps S611 and S612. That is, the channel CH corresponding to the hit pad body P (which is any one of CH1 to CH4 and hereinafter referred to as “channel CH (PN)”) and the hitting strength detected for the pad body P (hereinafter referred to as “channel CH (PN)”). , Referred to as “touch data TD”) is set in the channel buffer CHBUF (step S611). Next, the data in the channel buffer CHBUF is read, and the sound source (for example, when the pad body P1 is hit, the PN = 1 and the bass drum) is assigned to the channel CH (PN) when the data in the channel buffer CHBUF is read. PN) (step S612). At that time, the touch data TD is also sent to the tone generator 15 together with the channel CH (PN), and is generated from the speaker 4 as a tone with touch. Thereafter, this process is terminated.

  FIG. 7 is a flowchart showing the procedure of timer interrupt processing in the present embodiment. This process is executed in response to an interrupt signal generated by the timer 8 for the CPU 5.

  First, it is determined whether or not the RUN flag is set to “1” (step S701). As a result of the determination, if RUN = 0, the present process is terminated, whereas if RUN = 1, It is determined whether or not auto play (AP) indicating that execution of automatic performance processing is to be performed is set to “1” (step S702). If the result of the determination is AP = 1. Then, an automatic performance (accompaniment, etc.) process based on the automatic performance data is executed (step S703), and the process proceeds to step S704. On the other hand, if AP = 0, the process immediately proceeds to step S704.

  Here, the automatic performance data is composed of, for example, MIDI codes, and although not shown, initial setting data such as tempo data indicating the tempo of the entire song, and key-on and key-off events for instructing the sound generation and mute. It is mainly composed of data, timing data indicating the generation timing of these event data, and end data indicating the end of the song. The automatic performance data is stored in the storage device 11, for example, and is read out to the RAM 7 during the automatic performance processing. In the case of performing an automatic performance process that involves sound generation of a tone other than drum sounds, such as a piano, the sound of an instrument other than the drums is generated using channels other than channels 1-8. In that case, it is assumed that the number of channels is set to 9 or more (for example, 16).

  In step S704, an automatic rhythm and handling instruction process shown in FIG. 8 to be described later is executed. Next, the value of the TCL (tempo clock) pointer is incremented by "1" (step S705), and according to the TCL value. The timing lamp TL (see FIG. 5) in the display 12 is turned on (step S706). Here, in this embodiment, one measure is 96 beats, and in 4 beats, every 24 beats, 0 ≦ TCL ≦ 23, 24 ≦ TCL ≦ 47, 48 ≦ TCL ≦ 71, 72 ≦ TCL ≦ 95, respectively. Corresponding to the case, the timing lamps TL1, TL2, TL3, TL4 are turned on sequentially. Thereby, progress of a beat can be recognized.

  Next, it is determined whether or not the TCL pointer has reached “96” (step S707). If the result of the determination is that TCL = 96, the present process is terminated. If TCL = 96, TCL is determined to be TCL. The pointer is reset to “0” (step S708), and the display content on the display 12 is displayed as the next one bar portion in the currently processed rhythm data RHD (SEL) (including limb instruction displays H1 to H4). (Step S709). Thereby, as the music progresses, the pad body P to be hit, the hit timing, and the hand to be used for hitting (left or right, hereinafter referred to as “striking limb”) are visually recognized. In particular, since the limb instruction display is displayed in the vicinity of each musical note, the visibility is high. Thereafter, this process is terminated.

  The display on the display 12 is not limited to one bar display, and a plurality of bars may be displayed simultaneously.

  FIG. 8 is a diagram illustrating a flowchart of the automatic rhythm and handling instruction process executed in step S704 of FIG.

  First, in the rhythm data RHD (SEL) currently being processed, it is determined whether or not the data indicated by the address pointer Pr is code length data (step S801). If it is code length data, it is determined whether or not the value of the code length data is equal to the TCL value (step S802). As a result of the determination, if the value of the mark length data is not equal to the TCL value, the present process is terminated. If the value of the mark length data is equal to the TCL value, the address pointer Pr is incremented by “1” (step S803), the process proceeds to step S804.

  In step S804, channel data CH, rhythm sound source data, and touch data indicated by the address pointer Pr are sent to the musical tone forming unit 15. Thereby, according to the progress of the music, the tone of the percussion instrument specified by the rhythm sound source data is transmitted through the sound system 16 in the channel CH (RHD) (any of 5 to 8) specified by the channel data CH. It is pronounced with velocity defined by touch data.

  In step S805, the light source unit 30 is caused to emit light based on the channel data CH indicated by the address pointer Pr, the pad designation L / R data, and the touch data. That is, the pad body P (for example, CH (RHD) = corresponding to the channel number “CH (RHD) -4” corresponding to the channel CH (RHD) (any one of 5 to 8) defined by the channel data CH. The light source unit 30 (30L or 30R) on the same side as the hand defined by the pad designation L / R data among the light source units 30 of the pad body P1 if 5 and the pad body P2 if CH (RHD) = 6. Is made to emit light with the light emission intensity defined by the touch data. The corresponding light guide 32 (L or R) appears to shine due to the light emission of the light source unit 30. By looking at it, the pad body P to be hit, its hit timing, and the hit limb (left or right) according to the progress of the music (Right) is visually recognized. In particular, light emission in the vicinity of the pad body P is easy to visually recognize while performing a striking operation, and is suitable for a performance guide.

  Next, the address pointer Pr is incremented by “1” (step S806), it is determined whether or not the data indicated by the address pointer Pr is END data (step S807), and the data indicated by the address pointer Pr is END data. If not, the process ends. If it is END data, the RUN flag is set to “0” (step S808), and the process ends.

  7 and 8, the address pointer Pr is incremented repeatedly to generate a drum rhythm sequence from one piece of rhythm data RHD, and an automatic performance is performed in accordance with the drum rhythm sequence, and the display 12 and the light source The unit 30 gives a maneuvering instruction.

  When performing the rhythm guide performance using the rhythm data RHD with this musical instrument, the player uses the display 12 or the light emission of the light guide 32 of each pad body P as a clue, that is, the player instruction information, that is, the pad body to be hit, the hit timing, The batting is performed while recognizing the batting limb to be used for batting. At that time, the impact strength is also recognized by the brightness of the light guide 32. Then, a musical sound based on the rhythm data RHD is generated with a touch, and if the player strikes, a corresponding percussion sound is also generated with a touch by the processing of steps S610 to S612 in FIG.

  These will be described more specifically with reference to FIG.

  Each time the rhythm sound source assignment switch 17 (see FIG. 1) is turned on, the percussion instrument type, that is, the rhythm sound source assignment candidates are displayed on the display 12, so that the sound source to be assigned to any of the pad bodies P1 to P4 is displayed. Is displayed, if any of the pad bodies P1 to P4 is hit (pad-on), it is hit by the assignment process in a subroutine (not shown) executed in the “other process” of step S613 in FIG. The currently displayed sound source is assigned to the pad body P. When this is repeated for the number of pad bodies P, that is, four times, so-called user's drums in which the player arbitrarily assigns sound sources are obtained.

  For example, a bass drum may be assigned to the pad body P1, a hi-hat cymbal to the pad body P2, a tom tom to the pad body P3, and a bongo to the pad body P4. When the rhythm data RHD is selected by the switch 18, the rhythm data RHD is automatically selected. Corresponding assignment settings may be made.

  In any case, when the assignment is set, the limb instruction display H1 of the note M1 on the rhythm score shown in FIG. 5 is displayed in synchronization with the light emission timing of the timing lamp TL1 for timing instruction. The instruction “struck the hi-hat cymbal (here, the pad body P2) with the right hand” is prompted. At this time, the light source unit 30R of the pad body P2 also emits light.

  When the time for one beat has elapsed, an instruction to emit light from the timing lamp TL2 is received, and an instruction “hit the hi-hat cymbal (here, the pad body P2) with the left hand” is prompted. At this time, the light source unit 30L of the pad body P2 also emits light. When the time for one beat has further elapsed, an instruction to emit light from the timing lamp TL3 is received, and an instruction to “blow the tom (here, the pad body P3) with the right hand” is prompted. At this time, the light source unit 30R of the pad body P3 also emits light. Similarly, at the fourth beat, a display and a light emission instruction are made in the same manner as the first beat.

  The player strikes the pad bodies P2 and P3 by manual operation according to these series of instructions and repeats the practice. When one bar is completed, the next bar is instructed in the same way. When the same rhythm pattern continues, the same instruction mode is repeated. If the player follows this instruction and repeats the batting practice, he can acquire a subtle “paste”. In the above description, the instruction coincidentally with the beat is illustrated, but the note M1 and the limb instruction display H1 may be instructed at a timing slightly deviated from the beat timing. By repeating, you will get to know "paste".

  According to the present embodiment, since any one of the light source units 30L / R of the corresponding pad body P emits light based on the drum rhythm sequence generated based on the rhythm data RHD, the light guide that looks shining The pad body P corresponding to 32 is a pad body to be hit, and the light emission timing is easily recognized as the hit timing, and the same side of the light guide left and right halves 32L / 32R as the side that appears to be lit Is recognized as the batting limb. Therefore, it is possible to visually recognize the maneuvering instruction information, that is, the pad body to be hit, the hit timing, and the hitting limb, which can be used for the practice of playing the drums. In particular, light emission in the vicinity of the pad body P is easy to visually recognize while performing a striking operation, and is suitable for a performance guide. In addition, since the light emission intensity of the light source unit 30 is changed according to the touch data in the rhythm data RHD, it is possible to visually recognize the strength to be struck from the brightness of the light guide 32, and for performance practice. More useful.

  In addition to the above, the rhythm score is displayed on the display 12 based on the drum rhythm sequence, and the limb instruction display is displayed in the vicinity of each note in the rhythm score. The pad body P to be hit and the hit timing are recognized from the position, and the hit limb is recognized depending on whether the limb instruction display is displayed on the left or right of the note. Therefore, the operator instruction information can be visually recognized even by the rhythm score display, and the performance practice mode is further expanded. In particular, the limb instruction display is displayed in the vicinity of each note in the musical score essential for performance, so that the visibility is high. Moreover, since it is performed in conjunction with the display of the handling instruction information by the light guide 32, the visual recognition effect is further enhanced, and the performance practice according to the proficiency level is facilitated.

Further, since the sound generation channels (CH5 to 8) based on the drum rhythm sequence are different from the sound generation channels (CH1 to 4) based on the actual hitting on the pad body P, the musical sound based on the rhythm data RHD and the musical sound based on the real-time performance are used. Are pronounced independently and can be heard. In other words, it is possible to distinguish and recognize the sound by making it sound in a channel different from the sound channel generated by the player's actual strike. Accordingly, the recognition effect of the maneuver instruction information is visually considered, and the recognition effect is enhanced. In addition, the musical sound by the rhythm data RHD and the musical sound by the actual batting are recognized separately. By practicing with the aim of matching the pad bodies P (drum type information), the practitioner is fed back with audio performance assistance and can expect a learning effect from an audiovisual viewpoint. In other words, by practicing many times to match the rhythm guide, the timing and touch gradually match, so that the rhythm and touch can be acquired and a subtle “paste” can be acquired. Therefore, it is possible to make it possible to distinguish and listen to the musical sound by the rhythm data RHD and the musical sound by the actual batting, which can be used for the practice of playing the drums.

  Note that the arrangement and configuration of the light guide 32 are not limited to those illustrated as long as the correspondence with the left and right hands can be easily recognized, and may be arranged separately on the left and right. For example, the light guides may be disposed on the left and right sides of the back of the player of the pad body P (the shape may be a square instead of a circle). In addition, the configuration of the light emitting unit FU is not limited to that illustrated, and may be configured to be visually recognized. Instead of the combination of the light source unit 30 and the light guide 32, the light emitting unit FU may be configured by LEDs or fluorescent tubes for each limb. However, the form is not limited to a circle.

  In the present embodiment, in the handling instruction information display by the light source unit 30, it is instructed whether to strike with the left or right hand, but it goes without saying that this may be applied to the foot. . In that case, in addition to the light guide 32L / R, a light guide for a foot and a light source unit may be provided in the vicinity of the pad body P or the like. For example, from the viewpoint of the player, the left hand light guide and the light source unit are arranged close to the left rear of the pad plate 31, the right hand light guide and the light source unit are arranged close to the right rear of the pad plate 31, and the pad plate 31. What is necessary is just to arrange | position the light guide body and light source part for a leg in front (player side). Moreover, you may make it display the leg instruction | indication display for legs also on the display 12 below a musical note.

  In the present embodiment, the striking limb is instructed depending on which of the light source units 30L / R emits light. However, the present invention is not limited to this. For example, one light source unit is provided for each pad body P. In addition, the light emission color and the light emission mode may be variably configured, and the light source unit of the pad body to be hit may be configured to emit light in the light emission color or the light emission mode corresponding to the hitting limb. Thereby, the operator instruction information can be recognized with a simple configuration.

  The striking strength may also be displayed on the rhythm score on the display 12. In that case, for example, a predetermined meter display (by a hand or a numerical value) may be provided on the rhythm score, and the striking strength may be instructed by changing the display mode of the meter display for each striking strength. Or it is good also as a stepped display by a number. Thereby, it is possible to visually recognize not only the rhythm score but also the striking strength in addition to the maneuver instruction information.

  The rhythm data RHD may be acquired from the communication network 101 via the communication I / F 14. In this case, the rhythm data RHD may be processed in real time while being received through the communication I / F 14 without temporarily storing the rhythm data RHD in the RAM 7. The rhythm data RHD may be obtained separately from a portable storage medium.

  The present invention can also be applied to a keyboard instrument having a pad body corresponding to the pad body P. Further, even a keyboard instrument without a pad body can be applied to a keyboard instrument in which the tone color of a drum instrument is assigned (or assignable) to each key. In this case, the timbre assignment mode is not limited to the configuration of one timbre per key, and may be a keyboard instrument in which one timbre is assigned to a plurality of keys. In this case, performance guide LEDs provided for the left and right end keys of a plurality of keys to which the same tone color is assigned in the vicinity of each key (for example, LEDs arranged at the fulcrum portion of the key on the panel surface) By causing the LED to emit light, the LED may serve as a maneuver instruction.

  In this embodiment, the display of the maneuvering instruction information is performed by both the display on the display 12 and the light emission of the light source unit 30, but it may be performed by only one of them. Moreover, when only the display on the display 12 is performed, both the light source units 30L and 30R of the pad body P to be hit may be caused to emit light.

  In addition, while performing an automatic performance (accompaniment, etc.) based on the automatic performance data, the light source unit 30 emits light by the rhythm data RHD, and processing that does not generate the drum sound by the rhythm data RHD is possible. Also good. In that case, the player can practice the batting by listening to the guide by the light emission of the light guide 32 while listening to the automatic accompaniment. In this case, the display of the operator instruction information on the display 12 may not be performed.

  It should be noted that a similar effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention to the present instrument, in which case the data is read from the storage medium. The program code itself realizes the new function of the present invention, and the storage medium storing the program code constitutes the present invention. Further, the program code may be supplied via an electric transmission medium (for example, communication I / F 14), and in that case, the program code itself constitutes the present invention. As a storage medium in these cases, a floppy disk, a hard disk, an optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and the like can be used in addition to a ROM.
