2. Description of the Related Art In recent years, as a performance learning apparatus for an electronic keyboard instrument or the like that guides the performance of a keyboard, a device that has a light emitting means for each key and emits a light emitting means for a key to be pressed according to song event data has become widespread. ing. In this case, a method of causing the entire key to emit light has also been proposed, but in order to realize this method, it is necessary to make the key material diffusible and light-guided, which increases costs. There's a problem. For this reason, the light emitting means composed of light emitting elements such as LEDs (light emitting diodes) is exposed from the front surface of the key for each key, or embedded in the back surface of the key so that light emission can be seen from the front surface of the key. Many of them are widely used to guide the performance by causing the key portion to be depressed to emit light.
Furthermore, not only the light emission means of the key to be pressed is lighted, but also after the key is played, the light emission means of the key to be pressed next is lighted, so that the performer smoothly shifts to the next performance. A performance learning device that guides the user as possible is also proposed.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of a performance learning apparatus according to the present invention will be described with reference to FIGS. 1 to 11, taking an electronic keyboard instrument as an example.
FIG. 1 is a block diagram showing an internal configuration of an electronic keyboard instrument in this embodiment, FIG. 2 is a diagram showing a data format of music data of a performance learning song, and FIGS. 3 to 6 are flowcharts showing operations of performance learning processing, 7 to 11 are diagrams showing the relationship between the keyboard and the hand position.
In FIG. 1, a CPU 1 is connected to a ROM 3, a RAM 4, a switch unit 5, a song ROM 6, a keyboard 7, an LED group 8, and a sound source unit 9 via the system bus 2, and sends data and commands to and from these units. Give and receive. The ROM 3 stores a performance learning program executed by the CPU 1 and initial data. The RAM 4 is a work area of the CPU 1 and has various register, pointer, and flag areas necessary for executing the performance learning process program. The switch unit 5 includes a start / stop switch for starting or stopping automatic performance of the performance learning music and other switches. The song ROM 6 stores song data of performance learning songs. The keyboard 7 inputs to the CPU 1 the pitch, which is the key number of the key pressed according to the performance, and the velocity indicating the strength of the key pressed.
As shown in FIG. 7, the LED group 8 includes two LEDs provided for each key of the keyboard 7. Of the two LEDs, one LEDA (in FIG. 7, the white key LEDA11 and the black key LEDA13) is provided at the end of the performance side, that is, the front side of each key, and the other LEDB (in FIG. 7, The white key LEDB12 and the black key LEDB14) are provided opposite to the performance side, that is, at the end on the back side. The LEDA and LEDB of each key are turned on in response to the light emission command from the CPU 1 and turned off in response to the extinction command.
A tone generation circuit 10 is connected to the sound source unit 9, and a tone signal is supplied to the tone generation circuit 10 in accordance with a tone generation command from the CPU 1, and a tone signal supplied to the tone generation circuit 10 in response to a mute command from the CPU 1. Stop the signal and mute it.
[0009]
Next, the performance learning operation in the first embodiment of the present invention will be described. The performance lesson in this case is a mode in which the LED of a key to be depressed is lit as event data, and when the key is depressed, the mode shifts to the next event data, that is, a mode in which the music progresses in accordance with the correct performance. Is set to
The music data of the performance learning music stored in the music ROM 6 is composed of a plurality of event data and END data indicating the end of the music. Each actual event data is composed of note event data, control event data, and the like. The note event includes a pitch, that is, a key number, a flag indicating on / off, velocity data, and in the case of note-on data, a performance is performed. Consists of the position of the hand to be. However, in this embodiment, in order to make the performance learning operation easier to understand, as shown in FIG. 2, each event data is composed of key number data of a key to be pressed and hand position data. ing. The hand position is represented as a key number corresponding to the middle finger. For example, in FIG. 7, the key number of the key 17 corresponding to the middle finger 16 of the hand 15 to be played is stored in the music ROM 6 as the position of the hand.
[0010]
Therefore, in this embodiment, the start address is the key number of the key to be pressed first, the next address is the position of the hand pressing the key, that is, the key number corresponding to the middle finger, and the next address Corresponds to the key number of the key to be pressed, and the next address corresponds to the key number of the key pressed and the position of the hand, such as the position of the hand pressing the key, that is, the key number corresponding to the middle finger. Key numbers are arranged alternately.
Note that the number of keys to be pressed is not necessarily one. For example, when playing a chord with the left hand, there are a plurality of keys to be pressed simultaneously. When there are a plurality of keys to be pressed in this way, the note-on data in FIG. 2 is composed of a plurality of key numbers. However, the key number indicating the position of the hand is composed of the key number of one key corresponding to the middle finger.
[0011]
FIG. 3 is a main flowchart of the CPU 1 according to the first embodiment. In this flow, after a predetermined initialization process (step A1), a start / stop switch process (step A2) for detecting on / off of the start / stop switch of the switch unit 5 and a keyboard process for searching for a change in the keyboard 7 (step A2). Step A3), a light emission process (Step A4) for controlling light emission and extinction of the LED group 8 of the keyboard 7, and a loop process for repeatedly executing other processes (Step A5) are performed.
[0012]
FIG. 4 is a flowchart of the start / stop switch process in step A2 in the main flow. It is determined whether or not this switch is turned on (step B1), and if not turned on, this flow is terminated. When this switch is turned on, the start flag STF is inverted (step B2). Then, it is determined whether or not the STF has changed from “0” to “1” (step B3). When the STF changes to “1”, the start of automatic performance is instructed, so the start address is stored in the address register AD (step B4).
Next, the event data of the music ROM (AD) designated by AD is stored in the register NOTE (step B5). That is, since the event data at the start address of the music ROM is key press data, the key number is stored in the NOTE. Next, the AD address is incremented (step B6), and the key number indicating the position of the hand of the music ROM (AD) designated by AD is stored in the register HAND (step B7). Next, the LEDA of the key with the key number stored in the NOTE is turned on (step B8). That is, the performance is guided by turning on the LEDA of the key to be pressed at present. When the STF changes from “1” to “0” in step B3, it is a case where the stop of the automatic performance is instructed, and therefore all the LEDs are turned off (step B9). After turning on LEDA in step B8 or turning off all LEDs in step B9, the process returns to the main flow.
[0013]
FIG. 5 is a flowchart of the keyboard process in step A3 in the main flow. In this flow, the key is scanned (step C1), and it is determined whether there is a key change (step C2). If there is no key change, this flow ends. When there is a key change from OFF to ON, that is, when a key is pressed, the key number of the key press is stored in the register KEYON (step C3). Then, a note-on event is created (step C4). When there is a key change from on to off in step C2, that is, when the key is released, the key number of the key release is stored in the register KEYOFF (step C5). Then, a note-off event is created (step C6). Thereafter, the note-on event created in step C4 or the note-off event created in step C6 is sent to the sound source unit 9 (step C7). Then, the process returns to the main flow.
[0014]
FIG. 6 is a flow of the light emission process in step A4 in the main flow. First, it is determined whether or not STF is “1” (step D1). If STF is “1”, it is determined whether or not the NOTE key number and the KEYON key number match. (Step D2). If the key numbers do not match or if the STF is “0” in step D1, this flow is terminated.
When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LEDA or LEDB is turned off (step D3). Next, the AD address is incremented (step D4), and it is determined whether or not the music ROM (AD) is not END data (step D5). If it is event data instead of END data, the key number of the music ROM (AD) is stored in the register NEXTNOTE (step D6). Further, the AD address is incremented (step D7), and the key number corresponding to the position of the hand of the music ROM (AD) is stored in the register NEXTTHAND (step D8).
[0015]
Next, it is determined whether or not the key number stored in NEXTTHAND is within a range of a value obtained by subtracting “2” from the HAND key number and a value obtained by adding “2” to the HAND key number (step D9). ). That is, it is determined whether or not there is a key to be pressed next within a range of five keys centered on the HAND key number. In the example of FIG. 7, it is determined whether or not there is a key to be pressed next within the range of the hand width divided by the two dotted lines 18. As a result of the determination, if the key number stored in NEXTTHAND is within the range of the hand width, the LEDB corresponding to this key number is turned on (step D10). On the other hand, if the key number stored in NEXTTHAND is not within the range of the hand width, the LEDA corresponding to this key number is turned on (step D11).
[0016]
In FIG. 7, in the state where the LEDA 19 of the key to be pressed is lit, when the key is pressed as shown in FIG. 8, the LEDA of the three keys is hidden by the index finger, the middle finger, and the little finger. . Also, as shown in FIG. 9, when the position of the hand is further to the back side, the left LED LEDA is hidden by the thumb. In other words, when the key to be pressed next is guided while the key to be pressed is currently pressed, if the LEDA of the key is within the range indicated by the dotted line 18, the next hand 15 is performed by the playing hand 15. There is a possibility that the LEDA of the key to be pressed is hidden. In this case, as shown in FIG. 8, the LEDs B20 and 21 on the back side of the key are turned on. On the other hand, if the LEDA of the key to be pressed next is not within the range of the dotted line 18, the LEDs A22 and 23 on the near side of the key are turned on as shown in FIG.
Further, when there are a plurality of keys to be pressed next, and the case where the LEDA is within the range of the dotted line 18 and the case where the LEDA is not within the range of the dotted line 18 are mixed, as shown in FIG. LEDB24 is turned on, and LEDA25 on the front side of the key is turned on. Further, in the same manner in the performance of both hands, when the case where the LEDA is within the range of the dotted line 18 and the case where the LEDA is not within the range of the dotted line 18 are mixed, as shown in FIG. And the LEDA 29 on the front side of the key are lit.
Similarly, when a black key is to be pressed next, it is determined whether or not the LEDA is within the range of the dotted line 18, and the LEDB or LEDA is turned on according to the determination result. When the key to be pressed at present or the key to be pressed next is a black key, the NEXTNOTE determination range in step D9 may be set differently from the case of a white key.
[0017]
After LEDB is turned on in step D10 of FIG. 6 or LEDA is turned on in step D11, the key number of NEXTNOTE is stored in NOTE (step D12), and the key number that is the position of the NEXTTHAND hand is stored in HAND. (Step D13). That is, the key number of the key to be pressed next and the key number which is the position of the hand are stored in the corresponding registers NOTE and HAND as the key number of the key to be pressed and the key number of the hand. . Then, the process returns to the main flow.
If the song ROM (AD) is END data in step D5, the STF is returned to “0” (step D14), and all the LED groups are turned off (step D15). Then, the process returns to the main flow.
[0018]
As described above, in the first embodiment, it is determined whether or not the LEDA of the key to be pressed next exists within the range of the width of the hand operating the key to be pressed at present. If there is no LEDA in the LEDA, the LEDA is caused to emit light. If the LEDA of the key to be pressed next is within the range, the LEDB of the key to be pressed next is emitted. Therefore, when guiding the key to be pressed, the player can easily recognize the next key to be played regardless of the position of the hand playing the key to be played now.
[0019]
Next, a second embodiment of the performance learning apparatus according to the present invention will be described with reference to FIGS.
In the second embodiment, the internal configuration of the electronic keyboard instrument taken as an example of the performance learning apparatus is basically the same as the configuration of the electronic keyboard instrument of the first embodiment shown in FIG. Therefore, the second embodiment will be described with the aid of the electronic keyboard instrument shown in FIG. However, the music data of the performance learning music in the music ROM 6 in the second embodiment is composed only of the key number as shown in FIG. 12, and does not include the key number indicating the position of the hand. The switch unit 5 in the second embodiment is provided with a setting switch for setting the hand width by the performer.
Next, the operation of the performance learning process in the second embodiment will be described.
FIG. 13 is a main flowchart of the CPU 1 according to the second embodiment. In this flow, after a predetermined initialization process (step A1), a start / stop switch process (step A2) for detecting on / off of the start / stop switch of the switch unit 5, and a hand for setting the width of the key to be pressed. A width setting process (step A3), a keyboard process (step A4) for searching for changes in the keyboard 7, a light emission process (step A5) for controlling light emission and extinction of the LED group 8 of the keyboard 7, and other processes (step A6). Perform loop processing to be executed repeatedly.
[0020]
FIG. 14 is a flowchart of the start / stop switch process in step A2 in the main flow. It is determined whether or not this switch is turned on (step B1), and if not turned on, this flow is terminated. When this switch is turned on, the start flag STF is inverted (step B2). Then, it is determined whether or not the STF has changed from “0” to “1” (step B3). When the STF changes to “1”, the start of automatic performance is instructed, so the start address is stored in the address register AD (step B4).
Next, the key number of the music ROM (AD) designated by AD is stored in the register NOTE (step B5). Further, the key number of the music ROM (AD + 1) designated by the next address (AD + 1) is stored in the register NEXTNOTE (step B6). Next, the LEDA of the key with the key number stored in the NOTE is turned on (step B7). That is, the performance side LEDA is turned on to guide the performance. When the STF changes from “1” to “0” in step B3, it is a case where the stop of the automatic performance is instructed, and therefore all the LEDs are turned off (step B8). After turning on LEDA in step B7 or turning off all LEDs in step B8, the process returns to the main flow.
[0021]
FIG. 15 is a flow of the hand width setting process in step A3 in the main flow of FIG. It is determined whether or not the hand width setting switch is turned on (step C1). If this switch is not turned on, this flow is terminated. If this switch is turned on, whether hand width data has been input. It is determined whether or not (step C2). This data is input as the number of keys on the keyboard, that is, the pitch difference. When data is input, the data is stored in the register WIDTH (step C3). That is, the performer sets the number of keys corresponding to the width of his / her hand. After the data is stored, it is determined whether or not the end switch is turned on (step C4). If this switch is not turned on, the process proceeds to step C2 to wait for data input. When the end switch is turned on, this flow is ended and the process returns to the main flow.
[0022]
FIG. 16 is a flowchart of the keyboard process in step A4 in the main flow of FIG. In this flow, the key is scanned (step D1) to determine whether or not there is a key change (step D2). If there is no key change, this flow ends. When the key changes from off to on, that is, when the key is depressed, the key number of the depressed key is stored in the register KEYON (step D3). Next, a note-on event is created (step D4) and sent to the sound source unit 9 (step D5).
[0023]
In the second embodiment, as shown in FIG. 12, the music data does not include data indicating the position of the hand. For this reason, when a key is pressed, it cannot be recognized in advance whether the LEDA that is lit to guide the key to be pressed next is hidden by the hand. Therefore, it is determined whether or not the key number of NEXTNOTE that is the key to be pressed next is within the range of NOTE-WIDTH / 2 to NOTE + WIDTH / 2 that is the range of the width of the hand being pressed (step). D6). If the key number of NEXTNOTE is within this range, it is determined whether or not LEDA (NEXTNOTE) is lit (step D7). If it is lit, the LEDA (NEXTNOTE) is turned off. LEDB (NEXTNOTE) is turned on (step D8). Then, the process returns to the main flow.
[0024]
When there is a key change from on to off in step D2, that is, when the key is released, the key number of the key release is stored in the register KEYOFF (step D9). Then, a note-off event is created (step D10) and sent to the sound source unit 9 (step D11). Since the performance guide is generally a beginner, the hand often leaves the keyboard after the key is released. Therefore, it is determined whether there is any LEDB that is lit after the key is released (step D12). When there is an lit LEDB, all the LEDs A can be seen by releasing the key, so the LED B is turned off and the LED A provided for the same key is turned on instead (step D13). Then, the process returns to the main flow.
[0025]
FIG. 17 is a flow of the light emission process of step A5 in the main flow of FIG. First, it is determined whether or not the STF is “1” (step E1). If the STF is “1”, it is determined whether or not the NOTE key number and the KEYON key number match. (Step E2). If the key numbers do not match or if the STF is “0” in step E1, this flow is terminated.
When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LED is turned off (step E3). Next, the AD address is incremented (step E4), and it is determined whether or not the music ROM (AD) is not END data (step E5). If the key number is not END data, the key number is stored in the register NEXTNOTE (step E6).
[0026]
Next, it is determined whether or not the key number stored in NEXTNOTE is within the range of NOTE-WIDTH / 2 to NOTE + WIDTH / 2, which is the range of the width of the hand being pressed (step E7). If the key number of NEXTNOTE is within this range, LEDB (NEXTNOTE) is turned on (step E8). On the other hand, if the key number stored in NEXTNOTE is not within this range, LEDA (NEXTNOTE) is turned on (step E9). After the LEDB or LEDA is turned on, the key number of NEXTNOTE is stored in the NOTE (step E10), and the key to be pressed next is guided. Then, the process returns to the main flow.
If the song ROM (AD) is END data in step E5, the STF is returned to “0” (step E11), and all the LEDs are turned off (step E12). Then, the process returns to the main flow.
[0027]
As described above, in the second embodiment, the range of the width of the hand to be pressed is set in advance, and the LEDA of the key to be pressed next is within the range of the width of the hand to be operated. If there is no LEDA within the range, the LEDA is caused to emit light. If there is an LEDA of the key to be pressed next within the range, The LED B of the key to be pressed is emitted. Therefore, as in the case of the first embodiment, when guiding the key to be pressed, even when the LEDA of the key to be pressed next is covered by the hand playing the key to be currently played, The player can easily recognize the next key to perform. In addition, by setting the range of the width of the hand to be pressed to a range that can be changed according to the setting, a performance guide that can flexibly correspond to any performer, from a child with a small hand to an adult with a large hand.
[0028]
Next, a third embodiment of the performance learning apparatus according to the present invention will be described with reference to FIGS.
In the third embodiment, the internal configuration of the electronic keyboard instrument taken as an example of the performance learning apparatus is basically the same as the configuration of the first embodiment shown in FIG. Therefore, also in the third embodiment, the operation of the performance learning process will be described with the aid of the electronic keyboard instrument shown in FIG. However, the music data of the performance learning music in the music ROM 6 in the third embodiment is composed of a key number and a performance symbol as shown in FIG. The performance symbols include staccato and legato. FIG. 19 is a diagram showing the position of the finger 31 that touches the key 30 to be pressed in accordance with the performance symbol, and the positions of the LEDA 32 and LEDB 33 embedded in the key 30.
[0029]
Staccato is a method of playing with sound clearly separated. For this reason, as shown in FIG. 19 (1), the pressed finger 31 is closer to the front side than the LEDA 32. In comparison with this, in the case of a normal performance, as shown in FIG. 19B, the pressed finger 31 is located behind the LEDA 32. Legato is a way to play without letting you feel the breaks in the sound. For this reason, as shown in FIG. 19 (3), the pressed finger 31 is further on the back side than the LEDA 32. That is, the position of the finger to be pressed changes according to the performance symbol. Therefore, in the third embodiment, the light emission of the LED is controlled in accordance with the performance symbol of the music data.
[0030]
As the main flow of the CPU 1 in the third embodiment, either the main flow of the first embodiment shown in FIG. 3 or the main flow of the second embodiment shown in FIG. 13 can be applied. Therefore, the characteristic operation of the performance learning process in the third embodiment will be described here.
FIG. 20 is a flow of light emission processing in the third embodiment. First, it is determined whether or not the STF is “1” (step F1). If the STF is “1”, it is determined whether or not the NOTE key number matches the KEYON key number. (Step F2). If the key numbers do not match, or if the STF is “0” in step F1, this flow ends.
When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LEDA or LEDB is turned off (step F3). Next, the AD address is incremented (step F4), and it is determined whether or not the music ROM (AD) is not END data (step F5). If the key number is not END data, the key number is stored in the register NEXTNOTE (step F6). Further, the AD address is incremented (step F7), and the performance symbol of the music ROM (AD) is stored in the register CODE (step F8).
[0031]
Next, it is determined whether or not the NEXTNOTE key number is within the range of the width of the pressed hand (step F9). If the key number is within the range of the hand width, it is further determined whether or not the CODE performance symbol is staccato (step F10). If it is not the staccato, the LEDB (NEXTNOTE) corresponding to the key to be pressed next is turned on (step F11). On the other hand, if the key number stored in NEXTNOTE is not within this range, or if the CODE performance symbol is staccato, LEDA (NEXTNOTE) corresponding to the key to be pressed next is turned on (step F12). . After turning on LEDB (NEXTNOTE) or LEDA (NEXTNOTE), the key number of NEXTNOTE is stored in NOTE (step F13). . Then, the process returns to the main flow.
If the song ROM (AD) is END data in step F5, the STF is returned to “0” (step F14), and all the LED groups are turned off (step F15). Then, the process returns to the main flow.
