Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A. Configuration FIG. 1 is a block diagram showing a configuration of a performance practice device 100 according to an embodiment. In this figure, the keyboard 10 generates performance information such as key-on / key-off events, key numbers, and velocities in response to pressing and releasing keys. The LED unit 11 includes LEDs (light emitting elements) arranged for each key of the keyboard 10 and a driver (not shown) that drives the LEDs to be lit, and is designated according to a control signal supplied from the CPU 13. The key LED is turned on (or blinked) to guide the user to the key to be played now (or the key to be played next).

  The switch unit 12 has various operation switches arranged on the apparatus panel, and generates a switch event corresponding to a switch type operated by the user. As the main switches arranged in the switch unit 12, for example, in addition to a song selection switch for selecting a song to be used for practice, an instruction is given to reproduce each song in the normal order in each section of the song selected by the song selection switch operation. There are provided a normal switch, a random switch for instructing to play back each section of the selected song in random order, and an easy switch for instructing to play back each section of the selected song in easy order. The purpose of these switches (normal, random and easy) will be discussed later.

  The CPU 13 controls each part of the apparatus according to various switch events generated by the switch part 12. The processing operation of the CPU 12 according to the gist of the present invention will be described in detail later. The ROM 14 stores various control programs loaded on the CPU 13. The various control programs include a main routine, an array generation process, a section reproduction process, a section guide process, and a section recording process which will be described later.

  The RAM 15 includes a work area and a data area. In the work area of the RAM 15, various register / flag data used for the processing of the CPU 13 are temporarily stored. The data area of the RAM 15 is composed of a song data area, a section arrangement data area, a recording data area, and a performance data area.

  In the recording data area of the RAM 15, recording data including performance data of a melody part played by the user and music data of parts other than the melody part is recorded in the section music (described later). In the performance data area of the RAM 15, the contents of the recording data area are recorded for each section music. The performance data area is not limited to the RAM 15 and may be provided in an external storage medium such as a flash memory.

  In the song data area of the RAM 15, song data of a plurality of songs for practice are stored as shown in FIG. One practice song is composed of a song header and a plurality of sections (1) to (M). The plurality of sections (1) to (M) is, for example, a piece of music divided into phrases or a plurality of measures, and a piece of music in one divided section is referred to as a piece of music. The song header includes data indicating the number of segment songs and the difficulty level of the segment songs. The data representing the degree of difficulty specifically represents the order of ease of playing (or difficulty of playing) of each piece of music (each of the sections (1) to (M)).

  One section music is composed of music data (1) to (n) each representing a constituent sound of each part (melody part, accompaniment part, etc.) forming the music of the section. One piece of music data is expressed in a data format called a so-called relative time system in which time TIME and event EVENT are combined and stored in the order of time-series addresses corresponding to the progress of music. The time TIME represents the timing of the current event with the elapsed time from the previous event. The event EVENT mainly includes a note-on event that represents the pitch and volume of a musical tone to be pronounced and a note-off event that represents the pitch of a musical tone to be muted.

  As shown in FIG. 3, the section array data area of the RAM 15 includes a random array data area, an easy array data area, and a normal array data area. In the random array data area, the section songs (sections (1) to (M)) are arranged in random order with reference to the number of section songs included in the song header of the song selected according to the song selection switch operation. Random sequence data specifying the sequence is stored. Random array data is generated by an array generation process (see FIG. 6) described later according to a random switch operation.

  In the easy arrangement data area, each section song (sections (1) to (M)) is referred to by referring to data representing the difficulty level of the section song included in the song header of the song selected according to the song selection switch operation. Easy array data for designating an array arranged in order of ease of performance is stored. The easy array data is generated by an array generation process (see FIG. 6) described later in response to an easy switch operation.

  The normal arrangement data area refers to the number of segment songs included in the song header of the song selected according to the song selection switch operation, and each segment song (section (1) to (M)) is in normal order (song Normal array data for specifying the array arranged in the original array is stored. The normal array data is generated by an array generation process (see FIG. 6) to be described later in response to a normal switch operation. Each of the random, easy, and normal array data is composed of pointers (1) to (P) for designating the address of the music data according to the arrangement of the music of each section.

  Here, with reference to FIG. 4, an example of the arrangement of segment songs designated by random sequence data, easy sequence data, and normal sequence data will be described. For example, each section song of the song selected by the song selection switch operation is composed of section (1) to section (7) as shown in the example shown in FIG. 4, and the difficulty of each section song included in the song header is shown in FIG. “Section (7)”, “Section (1)”, “Section (4)”, “Section (2)”, “Section (5)”, “Section (3),“ Section (6) "

  In such a case, the random arrangement data generated in response to the random switch operation is, as illustrated in FIG. 4A, an order in which section songs are randomly arranged, for example, “section (5)”, “section ( 2) ”,“ Section (7) ”,“ Section (1) ”,“ Section (3) ”,“ Section (6), ”and“ Section (4) ”.

  As shown in FIG. 4B, the easy arrangement data generated in response to the easy switch operation includes “section (7)”, “section (1)”, “section (4) in which section songs are arranged in an easy order. ) ”,“ Section (2) ”,“ Section (5) ”,“ Section (3) ”, and“ Section (6) ”.

  As shown in FIG. 4C, the normal arrangement data generated in response to the normal switch operation is “section (1)”, “section (2)”, “section (3), which is the original arrangement of the songs. ”,“ Section (4) ”,“ Section (5) ”,“ Section (6), “Section (7)”.

  The configuration of the embodiment will be described with reference to FIG. 1 again. In FIG. 1, the display unit 16 is composed of an LCD panel or the like, and displays various setting states and operation states on the screen according to a display control signal supplied from the CPU 13. The sound source 17 is configured by a well-known waveform memory reading method, and includes a plurality of sound generation channels that perform time-division operation. The tone generator 17 stores waveform data of various timbres, and among these, reads out waveform data corresponding to a tone parameter supplied from the CPU 13 and generates a tone output. The sound system 18 converts the musical tone output of the sound source 17 into an analog musical tone signal, and then performs filtering such as removing unnecessary noise from the musical tone signal, and then level-amplifies the musical tone output from the speaker.

B. Operation Next, the operation of the embodiment having the above-described configuration will be described with reference to FIGS. In the following, the operation of the main routine will be described first, and then the operations of array generation processing, section reproduction processing, section guide processing, and section recording processing called from the main routine will be described.

(1) Operation of Main Routine When the performance practice device 100 is powered on, the CPU 13 executes the main routine shown in FIG. 5 and proceeds to step SA1, where various registers and flags stored in the work area of the RAM 15 are displayed. In addition to resetting the data to zero or setting an initial value, initialization for instructing the sound source 17 to perform initialization is performed. When the initialization is completed, the CPU 113 proceeds to step SA2 where, for example, the song data of the song to be used for performance practice is selected according to the song selection switch operation, or the random switch, the easy switch, and the normal switch are operated. In response to this, a switch process for selecting a section arrangement (any one of a random arrangement, an easy arrangement, and a normal arrangement) is executed.

  Subsequently, in step SA3, an array generation process is executed. As will be described later, in the array generation process, when the normal switch is turned on, normal array data for specifying an array in which the sections of the selected song are arranged in normal order (original arrangement of songs) is generated. The pointer (1) at the top of the array is designated. When the random switch is turned on, random array data for specifying an array in which the section songs of the selected music are arranged in random order is generated, and the pointer (1) at the head of the array is specified. When the easy switch is turned on, easy array data that refers to data representing the difficulty level of the section songs included in the song header of the selected song, and specifies an array in which each section song is arranged in the order in which it is easy to play And the pointer (1) at the top of the array is designated.

  Next, in step SA4, section reproduction processing is executed. As will be described later, in the section reproduction process, the song data that is sequentially read out according to the step of the pointer is reproduced, and when the read song data includes the note-on event of the melody part, the note-on event When the LED that is placed on the key of the pitch specified in the above is lit and the read song data includes a note-off event of the melody part, the key of the pitch specified by the note-off event is used. By turning off the arranged LED, the user is instructed of the position of the key to be pressed or released as a model for playing the section music.

  Next, in step SA5, section guide processing is executed. As will be described later, in the section guide processing, the song data is sequentially read and played according to the progress of the pointer, and at the same time, the note-on event of the closest melody part from the stepping pointer is searched and the corresponding note-on event is detected. The LED disposed on the key of the pitch included in is blinked to guide the user to the key to be pressed next. Each time the guided flashing key is pressed, the performance scoring value is added. On the other hand, if the wrong key is pressed after the flashing key has been turned on, the performance scoring is performed. If the scoring result (performance scoring value) is less than a predetermined point when the music data of the section music has been read out, the value is subtracted from the beginning of the section music, and repeated until it is possible to score more than the predetermined point.

  Subsequently, in step SA6, section recording processing is executed. As will be described later, in the section recording process, the song data is sequentially read in accordance with the progress of the pointer, and if the user performs a key operation before reaching the event timing of the read song data, the time from the song data reading time to the key operation is read. Performance data composed of the time TIME corresponding to the elapsed time and the event EVENT corresponding to the key operation is formed and stored in the recording data area of the RAM 15, while if the key operation corresponding to the song data is correct, the performance scoring value Is added, and if the key is operated incorrectly, it is deducted.

  Then, when the event timing of the read song data is reached and the song data is a note-on event of the melody part, the key LED corresponding to the note-on event is turned on to guide the key to be played to the user, When the user presses the key in response, performance data representing the key press is formed and stored in the recording data area of the RAM 15.

  When the guided key is not pressed and the wrong key pressing operation is performed, the performance scoring value is decremented. When the correct key pressing operation is performed, the LED of the pressed key is turned off. This series of processing is performed until all the music data of the section music has been read, and if the scoring result (performance scoring value) when all the reading has been completed is less than a predetermined point, the recording data area of the RAM 15 is cleared and the section music of the section music is cleared. Repeat from the beginning, and repeat until a scoring result equal to or higher than a predetermined score is obtained.

  Next, in step SA7, the recording data (the performance data of the section music and the music data other than the melody part) recorded in the recording data area of the RAM 15 by the section recording processing in step SA6 is divided into the performance data area of the RAM 15 by section music. save. In step SA8, it is determined whether or not all sections have been completed, that is, whether or not the processes in steps SA4 to SA6 described above have been executed for all section songs. If all the sections have not ended, the determination result is “NO”, the process proceeds to Step SA9, the pointer of the next section music is designated, and the process returns to Step SA4.

  On the other hand, when all the sections are completed, the judgment result at the above step SA8 is “YES”, and the process proceeds to step SA10, where the recording data of each section music stored in the performance data area of the RAM 15 is displayed in the normal arrangement order (original arrangement of the songs). In the subsequent step SA11, the recording data of the section songs combined in the normal arrangement order (original arrangement of the songs) is read from the performance data area of the RAM 15 and reproduced.

(2) Operation of Array Generation Process Next, the operation of the array generation process will be described with reference to FIG. When this processing is executed through step SA3 (see FIG. 5) of the main routine described above, the CPU 13 selects any of the normal switch, random switch, and easy switch in step SB1, step SB3, and step SB5 shown in FIG. It is determined whether the switch is turned on.

  If the normal switch is turned on, the determination result in step SB1 is “YES”, and the process proceeds to step SB2, where each piece of music (section (1) ˜1) constituting the music selected according to the music selection switch is operated. (M)) is generated in the normal sequence (original arrangement of the music), and normal sequence data designating the sequence is generated and stored in the normal sequence data area (see FIG. 3).

  For example, if the song data of the song selected by the song selection switch operation is composed of section (1) to section (7) as in the example illustrated in FIG. 4, it is illustrated in FIG. 4 (c). In addition, “Section (1)”, “Section (2)”, “Section (3)”, “Section (4)”, “Section (5)”, “Section (6),“ Normal sequence data designating the sequence to be “section (7)” is generated. Thereafter, the process proceeds to step SB7, where the pointer (1) at the head of the array in the normal array data is designated, and this process ends.

  If the random switch is turned on, the determination result in step SB3 is “YES”, and the process proceeds to step SB4, where each piece of music (section (1) ˜ (M)) is generated and random array data specifying an array arranged in random order is generated and stored in the random array data area (see FIG. 3).

  For example, if the song data of the song selected by the song selection switch operation is composed of sections (1) to (7) as in the example shown in FIG. 4, it is shown in FIG. 4 (a). In addition, the order of section songs randomly arranged, that is, "section (5)", "section (2)", "section (7)", "section (1)", "section (3)", "section ( 6) Random array data designating the array to be “section (4)” is generated. Thereafter, the process proceeds to step SB7, where the pointer (1) at the top of the array in the random array data is designated, and this process ends.

  When the easy switch is turned on, the determination result in step SB5 is “YES”, the process proceeds to step SB6, and the difficulty level of the section song included in the song header of the song selected in accordance with the song selection switch operation Referring to the data representing, easy array data for designating an array in which each piece of music (sections (1) to (M)) is arranged in order of performance is generated and stored in the easy array data area (see FIG. 3). .

  For example, as shown in FIG. 4, the song data selected by the song selection switch operation is composed of the sections (1) to (7), and the difficulty level of each section song included in the song header. “Section (7)”, “Section (1)”, “Section (4)”, “Section (2)”, “Section (5)”, “Section (3),“ Section (6) ” Then, as illustrated in FIG. 4B, “section (7)”, “section (1)”, “section (4)”, “section (2)”, “ Easy array data designating an array to be “section (5)”, “section (3), and“ section (6) ”is generated. Thereafter, the process proceeds to step SB7, and the pointer (1) at the top of the array in the easy array data is designated, and this process is terminated.

  In this way, in the array generation processing, when the normal switch is turned on, normal array data that specifies an array in which the section songs of the selected song are arranged in normal order (original arrangement of the songs) is generated. The pointer (1) at the head of the array is designated. When the random switch is turned on, random array data for specifying an array in which the section songs of the selected music are arranged in random order is generated, and the pointer (1) at the head of the array is specified. When the easy switch is turned on, easy array data that refers to data representing the difficulty level of the section songs included in the song header of the selected song, and specifies an array in which each section song is arranged in the order in which it is easy to play And the pointer (1) at the top of the array is designated.

(3) Operation of Section Reproduction Process Next, the operation of the section reproduction process will be described with reference to FIG. When this process is executed via step SA4 (see FIG. 5) of the main routine described above, the CPU 13 proceeds to step SC1 shown in FIG. 7, and reads the song data of the section song according to the currently designated pointer. Subsequently, in step SC2, the process waits until time TIME in the read music data elapses. That is, it waits until the event timing is reached.

  When the event timing of the read music data is reached, the determination result in step SC2 is “YES”, and the flow proceeds to step SC3. In step SC3, it is determined whether or not the event EVENT in the read music data is a melody part note-on event. If the event EVENT is a note-on event of the melody part, the determination result is “YES”, the process proceeds to step SC4, and the LED unit 11 is turned on so as to turn on the LED arranged in the pitch key included in the note-on event. Then, the process proceeds to Step SC7 described later.

  On the other hand, if the event EVENT in the read music data is not a melody part note-on event, the determination result in step SC3 is “NO”, and the flow advances to step SC5. In step SC5, it is determined whether or not the event EVENT of the read music data is a melody part note-off event. If it is not a note-off event, the determination result is “NO”, and the flow proceeds to Step SC7 described later.

  On the other hand, if the event EVENT in the read music data is a note-off event of the melody part, the determination result in step SC5 is “YES”, the process proceeds to step SC6, and the pitch included in the note-off event is determined. The LED unit 11 is instructed to turn off the LED arranged on the key.

  In step SC7, the sound source 17 is instructed to reproduce the music corresponding to the event. That is, if the event EVENT of the read song data is a note-on event, the tone generator 17 is instructed to generate a musical sound specified by the note-on event, while if the event EVENT of the read song data is a note-off event, The sound source 17 is instructed to mute the musical sound designated by the note-off event.

  Next, in step SC8, the pointer is incremented, and in the subsequent step SC9, it is determined whether or not there is music data corresponding to the incremented pointer, that is, whether all music data of one section music has been read. If all the music data of the section music has not been read, the determination result is “NO”, and the process returns to step SC1 described above. Thereafter, the above-described steps SC1 to SC9 are repeated until all the music data of the section music are read out.

  As described above, in the section reproduction process, the music data sequentially read according to the step of the pointer is reproduced. On the other hand, when the read music data includes the note-on event of the melody part, the note-on event When the LED arranged on the key of the specified pitch is lit and the read song data includes a note-off event of the melody part, it is allocated to the key of the pitch specified by the note-off event. By turning off the LED provided, the user is instructed of the position of the key to be pressed or released as a model for playing the section music.

(4) Operation of Section Guide Process Next, the operation of the section guide process will be described with reference to FIGS. When this process is executed through step SA5 (see FIG. 5) of the main routine described above, the CPU 13 proceeds to step SD1 shown in FIG. 8 and is closest to the song data of the section song corresponding to the designated pointer. Search song data including note-on event of melody part. Subsequently, in step SD2, the LED unit 11 is instructed to blink the LED arranged in the pitch key included in the note-on event of the searched music data. As a result, the user is guided to the next key to be pressed.

  Next, in step SD3, the music data of the section music corresponding to the designated pointer is read out. In step SD4, it is determined whether or not the time TIME in the read music data has elapsed, that is, whether or not the event timing has been reached. Hereinafter, the description will be divided into an operation before the event timing and an operation after the event timing.

<Operation before event timing>
If the event timing has not been reached, the determination result in step SD4 is “NO”, and the flow proceeds to step SD5. In step SD5, it is determined whether or not a blinking key is pressed as a key to be pressed next by blinking the LED. If the blinking key is not pressed, the determination result is “NO”, the process returns to step SD4, and it is determined again whether the event timing has been reached.

  Then, it is assumed that the user has pressed the blinking key before the event timing is reached. If it does so, the judgment result of the said step SD5 will become "YES", will progress to step SD6, and will add a predetermined value as a performance scoring value. In other words, if the flashing key is pressed before the timing to play, the present embodiment adds points. In addition, it is good also as an aspect further equipped with the process which deducts, if a key is pressed before the predetermined time from the timing which should be played originally.

  Next, in step SD7, the pointer is set to the music data searched in step SD1 (music data including the note-on event of the melody part). Thereafter, the process proceeds to step SD17, where the pointer is incremented, and in the subsequent step SD18, it is determined whether or not there is music data corresponding to the incremented pointer, that is, whether all music data of one section music has been read out. If all the music data of the section music has not been read, the determination result is “NO”, and the process returns to step SD3 (see FIG. 8).

<Operation after event timing>
Now, returning to step SD3, the music data corresponding to the stepped pointer is read, and when the time TIME in the read music data has passed and the event timing is reached, the determination result in step SD4 described above becomes “YES”. Thus, the process proceeds to step SD8. In step SD8, it is determined whether or not the event EVENT of the read music data is a note-on event of the melody part searched in step SD1.

  If it is not a note-on event of the searched melody part, the determination result here is “NO”, the process proceeds to step SD9, the music source corresponding to the event EVENT of the read music data is instructed to the sound source 17, and then the above-mentioned. The process proceeds to step SD17.

  On the other hand, if the event EVENT of the read music data is a note-on event of the melody part searched in step SD1, the determination result in step SD8 is “YES”, and the process proceeds to step SD10. The LED unit 11 is instructed to light up. This guides the user that it is time to press the blinking key.

  Next, in step SD11, as in step SD1, the song data including the note-on event of the nearest melody part is searched from the song data of the section song corresponding to the next pointer, and in the subsequent step SD12, the searched song data is searched. The LED unit 11 is instructed to blink the LED arranged in the pitch key included in the note-on event of the data. As a result, the user is guided to the next key to be pressed.

  Thereafter, the process proceeds to step SD13 shown in FIG. 9 and waits until the user performs a key pressing operation. When the user performs a key pressing operation, the determination result is “YES”, and the process proceeds to step SD14 to determine whether or not the key pressing operation is the correct key pressing, that is, the key that has changed from blinking to lighting the LED. Determine whether it was done. If the wrong key is pressed, the determination result is “NO”, the process proceeds to step SD15, a predetermined value is deducted as a performance scoring value, and then the process returns to step SD13.

  On the other hand, if the key is pressed correctly, the determination result in step SD14 is “YES”, the process proceeds to step SD16, and the LED unit 11 is instructed to turn off the LED arranged in the pressed key. Thereafter, the process proceeds to step SD17, where the pointer is incremented, and in the subsequent step SD18, it is determined whether or not there is music data corresponding to the incremented pointer, that is, whether all music data of one section music has been read out. If all the music data of the section music has not been read, the determination result is “NO”, and the process returns to step SD3 (see FIG. 8).

  On the other hand, when all the music data of the section music have been read out, the determination result in step SD18 is “YES”, and the process proceeds to step SD19. In step SD19, it is determined whether or not the scoring result (performance scoring value) is a predetermined point (for example, 85 points) or more. If the scoring result is equal to or higher than the predetermined score, the determination result is “YES”, and the present process ends.

  On the other hand, if the score is less than the predetermined score, the determination result in step SD19 is “NO”, and the process proceeds to step SD20. The pointer is first set so that the pointer corresponds to the first song data of the section song. After returning, the process returns to step SD1 shown in FIG. Therefore, the section guide process is repeated until a scoring result equal to or higher than a predetermined point is obtained.

  As described above, in the section guide processing, the song data is sequentially read and played according to the stepping of the pointer, and at the same time, the note-on event of the melody part closest to the stepping pointer is searched and the corresponding note-on event is detected. The LED disposed on the key of the pitch included in is blinked to guide the user to the key to be pressed next. Each time the guided flashing key is pressed, the performance scoring value is added. On the other hand, if the key is wrong, the performance scoring value is deducted, and the scoring result when all the song data of the section music has been read ( If the performance score is less than the predetermined score, the section music is re-executed from the beginning, and the processing ends when a score result equal to or higher than the predetermined score is obtained.

(5) Operation of Section Recording Process Next, the operation of the section recording process will be described with reference to FIGS. When this process is executed via step SA6 (see FIG. 5) of the main routine described above, the CPU 13 proceeds to step SE1 shown in FIG. 10 and reads the song data of the section song corresponding to the designated pointer. Subsequently, in step SE2, it is determined whether or not the time TIME in the read music data has elapsed, that is, whether or not the event timing has been reached. Hereinafter, the description will be divided into an operation before the event timing and an operation after the event timing.

<Operation before event timing>
If the event timing has not been reached, the determination result in step SE2 is “NO”, and the flow proceeds to step SE3. In step SE3, it is determined whether there is a key change, that is, whether there is a key event. If no key operation has been performed and no key event has occurred, the determination result is “NO”, and the process returns to step SE2.

  On the other hand, when a key event occurs due to a key operation (key depression or key release), the determination result in step SE3 is “YES”, and the flow proceeds to step SE4. In step SE4, the elapsed time from the music data read time to the key change is set to the time TIME, and in the subsequent step SE5, an event EVENT corresponding to the key change is generated. Specifically, a note-on event is generated when the key is pressed, and a note-off event is generated when the key is released. In step SE5, the sound source 17 is instructed to generate (or mute) a musical sound corresponding to the generated event. In step SE6, performance data composed of the time TIME generated in steps SE5 to SE6 and the event EVENT is formed as data representing the user's key operation and stored in the recording data area of the RAM 15. .

  Thereafter, the process proceeds to step SE7, where it is determined whether or not the key operation (key pressing or key release) is a correct key operation. Specifically, if the pitch key operation (key depression or key release) corresponding to the music data designated by the current pointer is performed, the determination result is “YES” as the correct key operation, and the process proceeds to step SE8. After adding the performance scoring value, the process returns to step SE2. On the other hand, if the key operation (key depression or key release) of the pitch corresponding to the music data designated by the current pointer is not performed, it is determined that the key operation is incorrect and the determination result in step SE7 is “NO”. Thus, the process proceeds to step SE9, the performance scoring value is deducted, and the process returns to step SE2.

<Operation after event timing>
When the event timing of the music data read according to the current pointer is reached, the determination result in step SE2 described above becomes “YES”, and the process proceeds to step SE10. In step SE10, it is determined whether or not the event EVENT in the read music data is a melody part note-on event. Hereinafter, the description of the operation will be made separately for the case of a note-on event for a melody part and the case for an event other than a melody part.

a. In the case of an event other than the melody part If the event EVENT in the read music data is an event other than the melody part, the determination result in step SE10 is “NO”, and the process proceeds to step SE19. Store in the area. Then, the process proceeds to step SE20 shown in FIG. 11, and the pointer is incremented. In the subsequent step SE21, it is determined whether or not there is music data designated by the incremented pointer. That is, it is determined whether or not all the music data of the section music has been read. If all the music data of the section music has not been read, the determination result is “NO”, and the process returns to step SE1 described above.

b. In the case of a melody part note-on event On the other hand, if the event EVENT in the read song data is a melody part note-on event, the determination result in step SE7 (see FIG. 10) is “YES”, and step SE11 is performed. Proceed to In step SE11, the LED unit 11 is instructed to turn on the LED disposed on the key corresponding to the pitch included in the note-on event. This guides the user to play the key.

  Next, in step SE12, the process waits until the user performs a key pressing operation. When the user presses the key, the determination result here is “YES”, and the flow proceeds to step SE13. In step SE13, an elapsed time from the time when the music data is read until the key is pressed is set to time TIME, and in step SE14, event EVENT corresponding to the key press (note-on including the pitch of the key pressed) Event). In step SE14, the sound source 17 is instructed to generate a musical sound corresponding to the generated note-on event. In step SE15, performance data composed of the time TIME generated in steps SE13 to SE14 and the event EVENT is formed as data representing the user's key pressing operation and stored in the recording data area of the RAM 15. .

  Next, in step SE16, it is determined whether or not the key depression performed in step SE12 is a correct key depression. If a wrong key is pressed, that is, a key different from the key guided by the LED lighting is pressed, the determination result is “NO”, the process proceeds to step SE17, and the performance scoring value is decremented. The process returns to SE12. Thereafter, steps SE12 to SE17 are repeated until the key guided by the LED lighting is depressed. When a correct key is pressed, the determination result in step SE16 is “YES”, and the process proceeds to step SE18, where the LED unit 11 is instructed to turn off the LED disposed on the pressed key.

  Thereafter, the process proceeds to step SE20 shown in FIG. 11, and the pointer is incremented. In the subsequent step SE21, it is determined whether or not there is music data designated by the incremented pointer. That is, it is determined whether or not all the music data of the section music has been read. If all the music data of the section music has been read, the determination result is “YES”, and the process proceeds to Step SE22.

  In step SE22, it is determined whether or not the scoring result (performance scoring value) is a predetermined point (for example, 85 points) or more. If the scoring result is equal to or higher than the predetermined score, the determination result is “YES”, and the present process is finished. If the scoring result is less than the predetermined score, the determination result in step SE22 is “NO”. Proceeding to step SE23, the pointer is returned to the beginning so that the pointer corresponds to the beginning music data of the section music, and in the subsequent step SE24, the recording data area of the RAM 15 is cleared, and then the above-mentioned step SE1 (see FIG. 10) is performed. Return processing.

  As described above, in the section recording process, the song data is sequentially read out according to the step of the pointer, and if the user performs a key operation before reaching the event timing of the read song data, the process from the time when the song data is read until the key operation is performed. Performance data composed of a time TIME corresponding to time and an event EVENT corresponding to a key operation is generated and stored in the recording data area of the RAM 15. On the other hand, if the key operation corresponding to the song data is correct, a performance scoring value is obtained. Points will be added, and if the key is operated incorrectly, points will be deducted.

  Then, when the event timing of the read song data is reached and the song data is a note-on event of the melody part, the key LED corresponding to the note-on event is turned on to guide the key to be played to the user, When the user presses the key in response, performance data representing the key press is formed and stored in the recording data area of the RAM 15.

  When the guided key is not pressed and the wrong key pressing operation is performed, the performance scoring value is decremented. When the correct key pressing operation is performed, the LED of the pressed key is turned off. This series of processing is performed until all the music data of the section music has been read, and if the scoring result (performance scoring value) when all the reading has been completed is less than a predetermined point, the recording data area of the RAM 15 is cleared and the section music of the section music is cleared. Repeat from the beginning, and repeat until a scoring result equal to or higher than a predetermined score is obtained.

  As described above, in the present embodiment, for example, song data (section music) of each section divided into a plurality of sections such as phrase units, the user-specified order (any of random order, easy order, or normal order) After generating the pointer to be played in step 1, sample playback (section playback processing) is performed. In the sample playback, the song data of the segment song is played according to the step of the generated pointer, and the position of the key to be released or released as a model for playing the segment song based on the song data is taught to the user. To do.

  When sample reproduction is completed, section practice (section guide processing) is performed. In the interval practice, the LED arranged on the key blinks based on the song data of the interval song that is read according to the generated step of the pointer to guide the user to the key to be pressed next, and according to the guide If the blinking key is pressed, the performance scoring value is added, while if the wrong key is pressed, the performance practice of decrementing the performance scoring value is repeated until a predetermined score or more can be scored.

  When you get used to the key operation until you can score more than a predetermined point by segment practice, perform segment recording (segment recording process). In section recording, an LED arranged on a key is lit on the basis of song data of a section song that is read according to the step of the generated pointer to guide the user to the key to be played, and the guided key is pressed. If the key is played, the performance scoring value is added, and if the key is pressed wrongly, the performance scoring is performed by deducting the performance scoring value. In section recording, the user's key operation in such performance practice is recorded (recorded) as performance data, and performance data for performance practice scored at a predetermined point or more is stored in memory.

  When a series of exercises (example playback, section practice, and section recording) has been executed for all section songs according to the order specified by the user, the performance data of each section song stored in memory is played back in the original order of the song To do. By doing this, it is not necessary to practice repeatedly over and over again until it becomes possible to play from the beginning to the end of the song as before, and practice is repeated so that each song can be played one by one. If you create performance data for the song and play it back, you will be able to listen to your own performance as if you played through one song, or to let others hear you. There is an effect that you can practice without getting tired without losing.

  In the embodiment described above, in order to simplify the description, the section reproduction process, the section guide process, and the section recording process in steps SA4 to SA6 illustrated in FIG. 5 are continuously performed. Instead, what kind of processing is performed on the user before each of the above-described processes is performed, for example, in the case of section playback processing (step SA4), before the start, It is also possible to provide a guidance display operation for guiding the user by displaying on the screen that the operation of teaching the position of the key to be released is performed. By doing so, the performance practice can be further facilitated.
