Description

  The present invention relates to an electronic keyboard instrument, and more particularly to an electronic keyboard instrument provided with a lesson function unit having a plurality of lesson functions for playing a music that cannot be played.

There are various lesson functions for electronic keyboard instruments. As represented by one-key play, many have been proposed from the past 20 years (1980s) by means of an automatic performance function that proceeds by matching only the key pressing timing.
A function that allows automatic performance to proceed by matching the key pressing timing and pitch is also proposed from almost the same time as described above, and various variations of these one-key plays have been developed. One of them is described in Patent Document 1, which is a very intelligent function.
JP 2004-101979 A

  Against this background, recently, as a plurality of lesson functions, a function (step 1) for automatically playing by only matching the timing at which the pad is hit or pressed, the key pressing timing and the pitch It has a function (Step 2) for advancing automatic performance by coincidence and a function (Step 3) for advancing automatic performance without waiting for a key to be depressed. In either case, the key to be pressed is displayed by lighting the lamp. An electronic keyboard instrument designed to do this was released (Casio LK-39).

In this electronic keyboard instrument, a circular speaker is arranged on the left and right in the operation panel portion behind the keyboard of the case, and a circular pad is arranged in the center, and a large number of operating elements are provided between the pad and the left and right speakers. (Keys and switches) are provided. The operation buttons (switch buttons) for selecting the plurality of lesson functions are arranged in the order of steps 1, 2, and 3 in an arc shape from the lower left side to the upper right side between the pad and the left speaker. It is established (aggregates). However, this is not in the order of the difficulty level of practice. In the difficulty, step 1 is “medium”, step 2 is “difficult”, and step 3 is “easy”.
In this way, since the operators for selecting the plurality of lesson functions are arranged regardless of the difficulty of the function to be selected regardless of the keyboard keys, the lesson function selection operability is good. Rather, the lesson function was difficult to understand.

  The present invention has been made in view of such a background, and is easy to operate even for beginners, easy to understand the lesson function, easy to select, and musical to be easy to practice. An object of the present invention is to provide an electronic keyboard instrument in which operators for selecting a plurality of lesson functions are arranged in consideration.

In order to achieve the above object, the present invention provides an electronic keyboard instrument comprising a keyboard having a plurality of keys, an operation panel unit having a plurality of operators, and a lesson function unit.

The plurality of lesson function selection operators are arranged linearly on the operation panel and in the order of difficulty of the lesson function to be selected along the key longitudinal direction at the standard key position in the key arrangement direction of the keyboard. And
The operator that selects the lesson function with the highest difficulty among the plurality of lesson function selection operators is also used as the operator for selecting the learning function, and the operator presses the lesson within a predetermined time set in advance. The lesson function having the highest difficulty level is selected when the learning function is selected, and the learning function is selected when pressed for a long time beyond the predetermined time .

Here, the “standard key” is, for example, a key corresponding to the main tone of the most common key in the music that can be played in a lesson (generally C key because there are many C major keys, G key if F major, F key if G major) It is.
Further, the lesson function of the lesson function section includes a function for performing an automatic rhythm performance. When the plurality of controls are pressed when they are turned off, the automatic rhythm performance is started. An automatic rhythm performance start / stop selection operation element for stopping automatic rhythm performance is included, and the start / stop selection operation element and the plurality of lesson function selection operation elements are arranged in the longitudinal direction of the key at the standard key position. You may make it arrange | position linearly along.

The first lesson function that automatically advances the automatic performance based on the music performance data stored in the plurality of lesson functions, and the automatic performance is advanced at a timing when any key of the keyboard is pressed. The second lesson function is a third lesson function that advances the automatic performance when the key pressed on the keyboard and the key press timing coincide with the next performance sound, and the third lesson function. Can be the most difficult lesson function .
For example, the lesson function selection controls for the first lesson function (lowest difficulty level), second lesson function, and third lesson function (highest difficulty level) are arranged from the farthest from the keyboard. It is better to arrange them in the order closer to each other or vice versa.

The electronic keyboard musical instrument according to the present invention configured as described above has a lesson function difficulty level in which a plurality of lesson function selection operators select all linearly along the key longitudinal direction at the standard key position in the key arrangement direction of the keyboard. Since the operators that select the lesson function with the highest difficulty among the multiple lesson function selection operators are also used as operators that select learning functions that are different from the lesson functions. also easy to understand the difficulty of each lesson function, selecting operation of each lesson function and learning function is easy, and the reference key of many songs capable practice will be indicated by the operator sequence , Many songs can make a strong impression of the meaning that starts there, making it easier for beginners to practice.

The ROM 12 is a read-only memory that stores data that does not need to be changed.

Here, FIG. 3 shows a configuration of data stored in the ROM 12.
As shown in the figure, the ROM 12 stores a control program executed by the CPU 11, initial setting values of the electronic keyboard instrument 1, music data that is performance data of a large number of music, and the like. Among them, the control program is a program for causing the CPU 11 to control each part of the electronic keyboard instrument 1 to realize various functions, and the initial setting value is used when performing normal performance, automatic performance, and music data reproduction. Are tempo data, tone color data, volume data, music name data, and the like used to determine general pronunciation contents and display contents.

  The music data is MIDI format data indicating the content of the music, and is composed of 16 tracks of performance data. For music data stored in advance in the electronic keyboard instrument 1, the first track is associated with the right hand (melody) part and the second track is associated with the left hand (accompaniment) part. The parts to which other tracks are associated differ depending on the music, and it is not necessary for all tracks to have data.

  The performance data of each track is information representing the playback content of the music, information for reproducing the main melody in the track associated with the melody part, and parts other than the main melody (chord performance, bass performance in the other tracks) , Rhythm performance, etc.). These pieces of information include combinations of timing data and event data arranged in the order of reproduction progress.

  Of these, the timing data is data indicating the timing (time) at which processing related to the event indicated by the corresponding event data is to be performed, and a plurality of events may correspond to one timing. The event data is data indicating the contents of various events for reproducing music, and includes a note-on event, a pitch change event, a note-off event, a tempo change event, a tone color change event, and the like.

  The ROM 12 for storing data as described above may be configured by a rewritable nonvolatile memory so that data can be added or updated. Further, the music data may not be stored in the ROM 12 but all the music data to be reproduced may be read from a storage medium or an external device described later.

Returning to the description of FIG. 2, the RAM 13 is used as a work area of the CPU 11, temporarily stores designated music data read from the ROM 12, and temporarily stores parameter values and the like. Memory.
The timer 14 is a time measuring means, and is used for timing control of processing related to events such as note-on and note-off according to a designated tempo when performing music based on music data.

The external storage medium I / F 15 is means for reading / writing data from / to an external storage medium such as a flexible disk drive (FDD) or a memory card slot. It is also possible to perform a performance based on the music data read from the storage medium loaded by the external storage medium I / F 15.
The MID II / F 16 is an interface for exchanging data according to the MIDI standard, and is used, for example, to communicate with another electronic musical instrument compatible with MIDI or a computer equipped with an application program that handles MIDI data.

The detection circuit 17 is detection means that detects the contents of operations performed on the keyboard 3 and the panel operator 21 and transmits them to the CPU 11.
The display circuit 18 is display control means for controlling display on the display device 23 in accordance with an instruction from the CPU 11. The display device 23 includes the LCD 6 provided on the operation panel unit 20 in FIG. 1, the key press guide LEDs 32 provided for each key 31 of the keyboard 3, and the like.

The tone generator circuit 19 generates waveform data with a plurality of tone generation channels based on the performance data of each track constituting the music data, generates a musical sound signal, and transmits it to the sound system 24.
The communication I / F 22 is an interface for performing communication such as an Ethernet (registered trademark) system or an IEEE (Institute of Electrical and Electronic Engineers) 1394 system, and the electronic keyboard instrument 1 is connected to a communication network through the interface. can do. Then, music data can be downloaded from an external device via the communication network and reproduced.

The electronic keyboard instrument 1 can realize the following functions by the above configuration.
First, it is possible to perform a normal performance in which a musical tone is generated and output according to the key pressing operation of the key 31 on the keyboard 3 by the user. Also, any one of the keys of the first lesson function (listening only function) L1 and the keyboard 3 which lights and displays the LED 32 of the key to be pressed while automatically playing all the parts of the designated music piece or the designated part is played. The second lesson function (timing coincidence progress function) L2, which advances the automatic performance at the timing of pressing, the automatic when the key pressed on the keyboard 3 and the key pressing timing coincide with the next performance sound The third lesson function (timing and pitch matching progress function) L3 for progressing the performance can be performed according to the selection by the lesson function selection operators 201 to 203, respectively. When executing the second and third lesson functions, the learner's key pressing operation is guided by turning on the LED 32 of the key to be pressed.

When the lesson function selection operator 203 is pressed for a predetermined time or longer, the learning function is selected and the code dictionary for code learning is processed.
When the automatic rhythm performance start / stop selection operator 204 is pressed, the start is selected to start the automatic rhythm performance, and when it is pressed, the stop is selected to perform the automatic rhythm performance. Stop.

Next, processing executed by the CPU 11 to realize these functions will be described. In addition, description is abbreviate | omitted about the process for implement | achieving another general function.
First, the processing of the main routine shown in FIG. 4 will be described.
When the power of the electronic keyboard instrument is turned on, this process is started. In step 01, a key release process relating to the keyboard 3 is executed to enable manual performance.

  Next, in steps S02 and S03, it is determined whether or not there is an L1 on event due to the pressing of the lesson function selection operator 201. If there is no L1 on event, the process proceeds to step S04, and if there is, L1 indicating the selected state of the first lesson function. The flag is inverted (0 for 1 and 1 for 0), and all the L2 to L4 mode flags indicating the selection states of the second and third lesson functions and the learning function are reset (set to 0). ).

  In the next steps S04 and S05, it is determined whether or not there is an L2 on event due to pressing of the lesson function selection operator 202. If there is no L2 on event, the process proceeds to step S06 as it is, and if there is, the second lesson function selection state is indicated. The L2 flag is inverted (0 if 1 and 1 if 0), and all the L1, L3, and L4 mode flags indicating the selection states of the first and third lesson functions and the learning function are reset (respectively) 0).

  In subsequent steps S06 to S11, it is determined whether or not there is an L3 on / off event caused by pressing or releasing the lesson function selection operator 203. If there is no L3 on / off event, the process proceeds to step S12. The flag is reset, the timer flag (F) that defines the operation of the timer that measures the ON time is set, and the accumulated value of the previous timer is reset. Further, the L3 mode flag indicating the selection state of the third lesson function is inverted (0 if 1 and 1 if 0), and the L4 mode flag indicating the learning function selection state is set to 0.

Then, it is determined whether or not a predetermined time set in advance has elapsed while the L3 mode flag is on (“1”). If not, the process proceeds to step S12. If it has elapsed, the L3 mode flag is reset. Then, the L4 mode flag is set to 1.
When the L3 on / off event is off in step S06, the timer flag is reset and the process proceeds to step S09.
Here, for example, the timer is measured by a timer interrupt process by an interrupt that occurs every 10 ms, and the timer counter is incremented by 1 only when the timer flag is 1. Therefore, 100 counts are 1 second. When the timer flag is 0, the previous integrated value is held.

  Through these processes, the lesson function selection operator 203 can be used for selecting the third lesson function L3 and the learning function L4. That is, if the operator 203 is pressed for a short time within a predetermined time, the L3 mode flag can be inverted to select or deselect the third lesson function, and if the operator 203 is kept pressed for a long time beyond the predetermined time. The learning function can be selected by setting the L3 mode flag to 1.

In steps S12 and S13, it is determined whether or not there is a rhythm (R) on event due to pressing of the start / stop selection operation element 204 of the rhythm run function. If there is no rhythm (R) on event, the process proceeds to step S14. If it is 1, it is set to 0, and if it is 0, it is set to 1).
In step S14, after executing a code dictionary processing subroutine which is a code learning function, the processing of the main routine is terminated. However, this main routine is repeatedly executed while the power is on.

Next, processing of each lesson function and learning function will be described.
FIG. 5 is a flowchart showing the process of the first lesson function (only listen function) executed when the L1 mode flag is 1. This process starts when the L1 mode flag becomes 1, and it is determined in step S21 whether or not the music data to be reproduced and the practice part are designated. If specified, the process proceeds to step S22 and subsequent steps. If not specified, “Song is not specified” or “Practice part is not specified” is displayed on the LCD 6 in step S28. Let the process finish.

  In step S22, the performance data of the track associated with the part designated as the practice part among the music data to be reproduced is sequentially read from the RAM 13 according to the progress of the music and transmitted to the tone generator circuit 19. Then, a musical tone is synthesized and a sound is generated at a volume set by the master volume 208.

  In step 23, performance data of all or a part of tracks other than the track associated with the part designated as the practice part among the music data to be reproduced is sequentially read out from the RAM 13 according to the progress of the music. Then, it is transmitted to the tone generator circuit 19 to synthesize a musical sound, and the sound is generated with a volume lower than the volume set by the master volume 208 by “predetermined volume”. The “predetermined volume” may be freely changed by the user. In addition, the volume of “other tracks” may be set to 0 so as not to generate sound.

Further, in step S24, the score of the part designated as the practice part is displayed on the LCD 6 based on the performance data read in step S22.
In step S25, on the basis of the performance data read out in step S22, the LED 32 corresponding to the key to be pressed is caused to emit light for the performance of the part designated as the practice part. To guide.
Although the processing of steps S22 to S25 is illustrated as being sequentially performed for convenience, in practice, the processing is performed simultaneously in parallel.

Thereafter, the processing ends when the performance data ends in step S26 or the L1 mode flag becomes “0” in step S27. However, if there is performance data and the L1 mode flag is “1”, the process returns to step S22. The above process is repeated.
Therefore, if the user designates the music piece to be practiced and the right or left hand part and presses the first lesson function selection operator 201 to select the first lesson function, the designated part of the designated music piece becomes the master volume. An automatic performance is performed at the volume set in 208, and an unspecified part is automatically played at a volume lower than the set volume.
Therefore, the practitioner can hear the performance sound of the specified part loudly and the sound of the performance of other parts can be heard softly, so that the part to be practiced is emphasized and easy to remember, and the relationship with other parts can be grasped. .

At that time, the score of the performance of the designated part is displayed on the LCD 6, and the key to be depressed on the keyboard 3 is guided by the illumination for the performance of the designated part, so that the user listens to the performance sound of the part. However, it is possible to grasp the sense of performance by watching the display of the score and following the illuminated keys of the keyboard 3 with the eyes.
In this embodiment, the key to be pressed is illuminated and guided by the LED, but the LCD 6 shown in FIG. 1 is used with a relatively large display screen, together with the score of the practice part. It is also possible to provide a function of displaying a keyboard diagram and guiding the key to be depressed in reverse video at the timing to be depressed. In this case, in step S25 of FIG. 5, instead of the process of causing the LED corresponding to the key to be pressed to emit light, the process of displaying the keyboard diagram and highlighting the key to be pressed at the timing to press the key is performed. To do.

  FIG. 6 is a flowchart showing processing of the second lesson function (timing only coincidence progress function) executed when the L2 mode flag is 1. This process starts when the L2 mode flag is set to 1. First, in step S31, it is determined whether or not the music data to be reproduced and the practice part are specified. If specified, the process proceeds to step S32 and subsequent steps. If not, in step S39, as in step S28 of FIG. 5, the LCD 6 displays "No music is specified" or "No practice part is specified", and the process is performed. finish.

In step S32, the same sound generation / display processing as in steps S22 to S25 of FIG. 5 is performed.
Thereafter, the process proceeds to steps S33 and S34 to determine whether or not there is a key depression at the timing to be depressed. If there is no key depression, the progress of the music is paused in step S36, and the process returns to step S34 to wait for the key depression and continue the music progression. If the key is pressed earlier than the timing at which the key should be pressed, the progression of the music may be continued after waiting for the key to be pressed.
When the performance data ends in step S37, the process ends. If the performance data does not end, it is determined in step S38 whether an end declaration has been made by the end-related operator. If so, the process ends. If not, the process returns to step S32 and the above process is repeated.

  According to this second lesson function, in order to play the specified part of the specified music, when any key on the keyboard 3 is pressed at the timing to be pressed, the music progresses, and the master volume 208 Plays at the set volume, and parts that are not specified are played at a volume lower than the set volume. If the key is not pressed at the timing when the key is to be pressed, the progress of the music is paused, and the music progresses and is played after the key is pressed.

As a result, one finger play can be performed, and the key pressing timing of the practice part can be practiced. Also in this case, since the other parts are played with a small sound, the relationship with the other parts can be grasped.
Also in this case, the musical score during the performance of the designated part is displayed on the LCD 6, and the key to be pressed on the keyboard 3 is guided by illumination for the performance of the designated part. Alternatively, as described above, the keyboard may be displayed on the LCD 6 and the key to be pressed may be highlighted.

FIG. 7 is a flowchart showing processing of the third lesson function (timing and pitch matching progress function) executed when the L3 mode flag is 1. This process starts when the L3 mode flag becomes 1, but the same processes as steps S31 to S33 and S35 to S39 in FIG. 6 described above are performed except for step S44 among steps S41 to S49.
In step S44, it is determined whether or not there is a key depression identical to the pitch data of the key to be depressed for the performance defined in step S42. If there is the same key press, the process proceeds to step S45 to continue the music progress. If there is no key press, the music progress is paused in step S46 and the process returns to step S44. Wait for it to continue with the music.

  According to the third lesson function, in order to play the specified part of the specified music, the music progresses when the key of the pitch to be pressed on the keyboard 3 is pressed at the timing to be pressed. The performance is performed at the volume set by the master volume 208, and the part not specified is also played at a volume lower than the set volume. If the key of the pitch to be pressed is not pressed at the timing to be pressed, the progress of the music is paused, and the music advances and plays after the key of the pitch to be pressed is pressed. Is done.

FIG. 8 is a flowchart showing a code dictionary process which is a code learning function executed in step S14 of FIG.
When this process starts, it is first determined in step S51 whether or not the L4 mode flag is 1, and if it is 0, nothing is done and the process returns to the main routine of FIG. If the L4 mode flag is 1, the learning function is selected, and the process proceeds to step S52. Only the root key (the key of the chord of the chord) is pressed by the keyboard 3, or the number of the root key and the numeric key 210 are pressed. (For example, C7-7) Wait for completion of code specification by input or alphabet input (for example, “major” or “minor”) by a combination of the root key and the numeric keypad 210. A complete code name may be input from the numeric keypad 210.
Alternatively, when entering this mode (L4 = 1), the keyboard is split and divided into a root designation key group and a kind designation key group, and by inputting a root key and a kind designation key (for example, “m7: minor seventh”). The three keys to be pressed may be displayed on the keyboard diagram of the LCD 6 to complete the chord designation.

When the chord designation is completed, the LED 32 corresponding to each key of the chord constituent sound is caused to emit light. When there are a plurality of chord candidates, the LED 32 corresponding to the most representative chord constituent sound is caused to emit light. Then, it waits for the plurality of keys defined in step S54 to be simultaneously turned on (pressed), and when the plurality of defined keys are simultaneously turned on, in step S55, the pitches corresponding to the keys of the chord constituent sounds Is generated (correct answer string generation) and the process returns to the main routine of FIG.
According to this chord learning function, when a chord is designated only by pressing the root key or by a number or alphabet, or by other methods as described above, each key of each constituent sound of the chord is displayed by light emission of the LED. Therefore, a desired chord can be played by simultaneously pressing the illuminated keys.

FIG. 9 is a flowchart of an operation performed by a timer interrupt for each minimum rhythm unit in the rhythm run function which is an automatic rhythm performance function .
This process always starts with a timer interrupt for each minimum unit of rhythm. First, in step S61, it is determined whether or not the rhythm run mode (RUN flag is 1). If it is not the rhythm run mode, the process directly returns to the main routine. . If it is the rhythm run mode, the process proceeds to step S62, and the rhythm type data (waltz, rumba, zilba, etc.) selected by the rhythm type selection means and a plurality of rhythm sound source type data to be sounded according to the rhythm type ( It is determined whether there is sound source data at the intersection of the matrix of the hi-hat, cymbal, snare drum, bass drum, etc.) and the count data counted for each rhythm interrupt. If there is no sound source data at the intersection of the matrix, the process returns to the main routine as it is. If there is sound source data at the intersection of the matrix, the process proceeds to step S63 and the sound of the sound source data defined above is generated. Return to the main routine.

As described above, the electronic keyboard instrument of the above-described embodiment has a difficulty of the lesson function in which a plurality of lesson function selection operators are selected linearly along the key longitudinal direction at the standard key position in the key arrangement direction of the keyboard. Since the operators that select the lesson function with the highest difficulty among the multiple lesson function selection operators are also used as operators that select a learning function different from the lesson function, the lesson is also used for beginners. Since the difficulty level of the function is easy to understand, the selection operation of each lesson function and learning function is easy, and the reference keys of many songs that can be practiced are indicated by the operator string, so many songs Can impress the meaning that starts from there and make it easy for beginners to practice. Furthermore, when practicing with the lesson function selected by the above controller, the designated practice part plays at the set volume, and the other parts play at a volume lower than the set volume. As a result, the practice part is emphasized and easy to remember, and it is possible to effectively practice each stage while grasping the relationship with other parts.

As is apparent from the above description, the electronic keyboard instrument according to the present invention has a plurality of lesson functions and a learning function different from them, and can be used for various electronic keyboard instruments that can be selected and executed as appropriate. Therefore, it is possible to improve the understanding of these functions and the operability of selecting and selecting functions, and even a beginner can easily practice playing a desired music piece.
