BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a performance training apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a system to which a performance training device according to the embodiment is applied. A keyboard device 10 and a personal computer 20 as a performance training device are connected by a MIDI cable 30. In this system, the user plays the keyboard device 10 while watching performance instructions such as a musical score of a practice song displayed on the personal computer 20, and MIDI data corresponding to the performance is transmitted to the personal computer 20 via the interface 7. The personal computer 20 displays the information in accordance with the MIDI data transmitted from the keyboard device 10 and controls the progress of the performance instruction.
The keyboard device 10 has a full-fledged specification including a plurality of switches such as a key range and tone setting of 88 keys, a MIDI channel designation, a medium specification of 61 keys, and a simple specification of 37 keys. And various other specifications.
[0011]
FIG. 2 is a block diagram showing the configuration of the personal computer 20. A CPU 1 composed of a microprocessor or the like is connected to an HD 3, a RAM 4, a keyboard 5, a display 6, an interface 7, and a sound source 8 via a system bus 2, and exchanges data and commands with these units. , And controls the personal computer 20. Hereinafter, the function of each unit will be described.
[0012]
The HD 3 is a hard disk, which includes a program of an operation system (OS), an application program such as a performance training program executed by the CPU 1, a plurality of music data for performance training, and various types of data set in the initialization processing. Initial value data and the like are stored in advance.
[0013]
The RAM 4 is a work area of the CPU 1, such as an area for various registers and flags required for executing an application program such as a performance training program, an area for displaying an image of one screen displayed on the display 6, and the like. Is provided. The keyboard 5 inputs commands and data to the CPU 1 according to user operations. The display 6 displays the image on the screen according to the input of the image data developed in the image drawing area by the display control process of the CPU 1. Although not shown in the figure, a pointing device such as a mouse is connected to the keyboard 5 or the system bus 2, and an icon at an arbitrary position on the screen of the display 6 can be designated.
[0014]
The interface 7 fetches MIDI data transmitted from the keyboard device 10 shown in FIG. 1 via the MIDI cable 30 and inputs the MIDI data to the CPU 1. Therefore, irrespective of the specifications of the keyboard device 10, at least a key number corresponding to a key press event, ie, a key-on event or a key release event, ie, a key-off event, and MIDI data of velocity indicating the strength of key press are generated by the interface 7 according to the performance of the user. And input to the CPU 1.
[0015]
The sound source 8 is connected to a sound system 9 composed of a D / A converter, an amplifier, a speaker, and the like, and responds to MIDI data captured via the interface 7 or music stored in the HD 3. In response to the automatic performance processing of the data, waveform data of a musical tone is generated and output to the sound system 9 according to a sound generation instruction or mute instruction command from the CPU 1 and the musical sound data, or the output is stopped to mute the sound. .
[0016]
Next, the operation of the personal computer 20 having the configuration shown in FIG. 2, that is, the performance learning apparatus, will be described with reference to the flowchart of the CPU 1 shown in FIGS. 3 to 9 and the screen of the display 6 shown in FIGS. .
FIG. 3 is a main flowchart. When the power is turned on, first, an initialization process is performed (step A1). In this initialization process, the registers, flags, and areas of the video RAM of the RAM 4 are initialized. For example, the reproduction flag PF is reset to "0 (reproduction stopped state)", the mode flag MF is set to "0 (idle state)", and the key-on flag KO is reset to "0". Also, the state of the performance lesson selected by the user is set as a default. For example, the music number of the performance training is set to the first music number, and the melody part performance by only the right hand, the chord part performance by only the left hand, and the part performance by both hands are set.
[0017]
Further, an initial screen as shown in FIG. Similarly, in the initial screen and other screens, at the upper left of the screen, five icons such as a play icon 11, a play stop icon 12, a fast forward icon 13, a fast reverse icon 14, and a MODE icon 15 are displayed. These icons are designated by a switch on the keyboard 5 or a pointing device. The function of each icon will be described later.
[0018]
In FIG. 3, after the initialization process in step A1, the setting process (step S1) is performed according to the operation of the keyboard 5 or the pointing device. A2), reading the music data of the performance lesson, controlling the display of the score image and the keyboard image, inputting the MIDI data from the interface 7, performing the sound processing for the sound source and controlling the mute instruction (step A3), and the like. The process (step A4) is repeatedly executed.
[0019]
4 to 7 are flowcharts of the setting process in step A2 in the main flow. In this flow, first, it is determined whether the reproduction flag PF is “1 (reproduction state)” or “0 (stop state)” (step B1). If the PF is “1”, this flow is ended and the flow returns to the main flow. If the PF is "0", it is determined whether the value of the mode flag MF is "0", "1", "2", "3", or "4" (step B2). . If the MF is “0”, the MFP is in an idle state, and it is determined whether or not the MODE icon 15 has been designated while the initial screen of FIG. 10 is displayed (step B3). If the MODE icon is not specified, this flow is terminated and returns to the main flow, and the idle state is maintained.
[0020]
When the MODE icon is designated, a mode select screen is displayed (step B4), and MF is set to "1" (step B5). Then, this flow ends and the flow returns to the main flow. FIG. 11 is a diagram of the mode selection screen displayed on the display 6. On this screen, the designated MODE icon 15 is displayed in color (hatched in the figure), and three modes of “1. music selection”, “2. part selection”, and “3. key range setting” are displayed as options. Then, any mode can be selected by inputting a mode number from the keyboard 5.
[0021]
If the MF is “1” in step B2, that is, if the mode selection screen of FIG. 11 is displayed, it is determined whether or not the MODE icon has been designated (step B6). When this icon is designated, the screen returns to the previous screen display (step B7), and the MF is set to "0" (step B8). Therefore, the display returns to the initial screen display of FIG. That is, each time the MODE icon is designated, the idle state and the mode select state are switched. If the MODE icon is not specified, it is determined whether or not a mode number has been input from the keyboard 5 (step B9). If there is no input of the mode number, this flow ends and the flow returns to the main flow.
[0022]
If a mode number has been input, it is determined whether the mode number is "1", "2", or "3" (step B10). When the input mode number is "1" and the music selection is set, a music selection screen is displayed (step B11), and the MF is set to "2" (step B12). Then, this flow ends and the flow returns to the main flow. FIG. 12 is a diagram of a music selection screen displayed on the display 6. On this screen, a list of a plurality of songs is displayed. The user can select one tune by inputting a tune number from the keyboard 5.
[0023]
If the input mode number is "2" and part selection is selected in step B10, a part selection screen is displayed (step B13), and MF is set to "3" (step B14). Then, this flow ends and the flow returns to the main flow. FIG. 13 is a diagram of a part selection screen displayed on the display 6. On this screen, three part performances of "1. right hand (melody)", "2. left hand (chord)", and "3. both hands" are displayed as options. Either part can be selected.
[0024]
When the input mode number is "3" and the key range setting is selected in step B10, the minimum key request screen is displayed (step B15), and the MF is set to "4" (step B16). . Then, this flow ends and the flow returns to the main flow. FIG. 14 is a diagram of the minimum key request screen displayed on the display 6. In response to the message “press the lowest key” on this screen, the user presses the key with the lowest pitch on the keyboard device 10. Alternatively, the user depresses the lowest key in the key range determined to be playable by the user.
[0025]
If the value of the MF is "2 (song selection mode)" in step B2, it is determined whether or not a song number has been input from the keyboard 5 in the flow of FIG. 5 (step B17). If no music number is input, this flow is terminated and the flow returns to the main flow. When the music number is input, the music number is stored in the register SN (step B18). If the value of the MF is "3 (part selection mode)" in step B2 of FIG. 4, it is determined whether or not a part number has been input from the keyboard 5 in the flow of FIG. 5 (step B19). If the part number has not been entered, this flow ends and the flow returns to the main flow. When the part number is input, the part number is stored in the register PN (step B20).
[0026]
After the music number is stored in the SN in step B18 and the part number is stored in the PN in step B20, all the note (pitch) data corresponding to the SN and PN are read (step B21). Next, the key number of the highest note is stored in the register HN, and the key number of the lowest note is stored in the register LN (step B22). Then, the key number of LN is subtracted from the key number of HN, and the subtracted value is stored in the register WN (step B23).
[0027]
In the MIDI data, a key number (key number) of a keyboard is associated with a pitch. For example, the key number of the pitch of “C-2” corresponds to “0”, the key number of the pitch of “G8” corresponds to “127”, and the key number becomes “1” every half pitch. Assigned to increase. In the process of step B22, the key numbers corresponding to the respective pitches of the highest note and the lowest note of the selected music are stored in the registers HN and LN. Therefore, the value of the register WN corresponds to the range of the key number corresponding to the range of the selected music piece. That is, it corresponds to the key range in which the selected music piece can be played.
[0028]
When the MF is “4 (key range setting mode)” in step B2 in FIG. 4, the minimum key request screen shown in FIG. 14 is displayed. In this case, in the flow of FIG. 6, it is determined whether or not a key-on event has been input from the keyboard device 10 via the interface 7 (step B24). If there is no key-on event input, this flow ends and the flow returns to the main flow. If there is a key-on event input, it is determined whether the key-on flag KO is "0" or "1" (step B25). KO is reset to "0" in the initialization processing as described above, and is set to "1" when a key-on event is first input in the key range setting mode.
[0029]
If KO is "0" when a key-on event is input, the key number is regarded as the lowest key number and stored in the register LK (step B26). Next, the highest key request screen is displayed (step B27), and KO is set to "1" (step B28). Then, this flow ends and the flow returns to the main flow. FIG. 15 is a diagram of the highest key request screen displayed on the display 6. The user presses the highest key of the keyboard device 10 in response to the message of "press the highest key" on this screen. Alternatively, the highest key in the key range determined to be playable by the user is pressed. After setting KO to "1" in step B28, the MF maintains the state of "4", so the main flow of FIG. 3 goes through step B2 of the setting process of FIG. Move to
[0030]
In this case, since KO is “1”, the key number of the lowest key stored in the LK is the highest key number in the second key-on event input in the state of the highest key request screen in FIG. It is determined whether the pitch is lower than the key number (step B29). If the key number of the LK is higher than or the same as the key number of the highest key, the key range cannot be set, so this flow is terminated and the flow returns to the main flow. At this time, a warning may be displayed by displaying a message indicating that the key range cannot be set and the reason therefor.
[0031]
If the key number of the LK is lower than the key number of the highest key, the key number of the input highest key is stored in the register HK (step B30), and KO is set to "0" (step B31). Next, the key number of LK is subtracted from the key number of HK, and the subtracted value is stored in the register WK (step B32). That is, the key range of the keyboard device 10 is stored in the WK. After this, or after storing the value in WN in step B23 in FIG. 5, the process proceeds to the flow in FIG. 7, and it is determined whether the value of WK is smaller than the value of WN (step B33). At this time, if only one of the value of WK or the value of WN is stored, the other value is compared using a default value.
[0032]
If the value of WK is smaller than the value of WN, that is, if the key range of the keyboard device 10 is smaller than the key range corresponding to the range of the selected song, there is a pitch that cannot be played in the selected song. become. In this case, a warning message of "There is a pitch outside the key range" is displayed for a predetermined time, for example, about 3 to 4 seconds (step B34). FIG. 17 is a diagram of a screen of a warning display displayed on the display 6.
A list of playable songs may be displayed on the warning display so that the user can select a new song from the list.
[0033]
When the value of WK is equal to or greater than the value of WN in step B33, or after the warning display in step B34, a value obtained by adding half of the key range of WN to the key number of LN, that is, the center in the range of the selected music piece. Is calculated, and a value obtained by adding half of the key range of WK to the key number of LK, that is, the central key number in the key range of the keyboard device 10 is calculated. Then, the central key number in the key range of the keyboard device 10 is subtracted from the key number corresponding to the central pitch in the musical range of the selected music, and the subtracted value is divided by the number of keys of one octave “12”. Is rounded, and the obtained integer value is stored in the register SFT (step B35).
[0034]
Next, the value obtained by multiplying the value of SFT by “12” is added to the key number of LK, the added value is used as the lowest key, and the value obtained by multiplying the value of SFT by “12” is added to the key number of HK. Then, a keyboard image is generated with the sum as the highest key (step B36). Thereafter, the flow shifts to step B4 in the flow of FIG. 4 to display the mode select screen shown in FIG.
[0035]
FIGS. 8 and 9 are flowcharts of the performance processing in step A3 in the main flow of FIG. In this flow, first, it is determined whether or not the mode flag MF is “0” (step C1). If the MF is a value other than “0”, that is, if it is in the setting mode, it is not possible to transition to the performance processing, so this flow is ended and the flow returns to the main flow. When the MF is “0” and the idle state, the musical score image is generated according to the music number stored in the register SN, and the musical score image is generated together with the keyboard image generated in step B36 in the setting processing flow of FIG. It is displayed on the screen of the display 6 (step C2). FIG. 17 is a diagram showing a screen displaying the first musical score image 16 of the selected music and the keyboard image 17 of 76 keys, and FIG. 18 shows the first musical score image 16 of the selected music and the keyboard image 17 of 37 keys. It is a figure of a screen.
[0036]
After the screen as shown in FIG. 17 or FIG. 18 is displayed in step C2, it is determined whether or not any of the icons at the upper left of the screen has been designated, and if so, the processing corresponding to the designated icon is performed. . In the flow of FIG. 8, it is determined whether or not the playback icon 11 has been designated (step C3). When this icon has been designated, it is determined whether or not the playback flag PF is "0 (stop state)". (Step C4). If the PF is "0", the PF is set to "1 (reproduction state)" (step C5), and the reproduction processing is performed (step C6). In the reproduction process, the music data stored in the ROM 3 is sequentially read out, scrolling the musical score image 16 displayed on the screen of the display 6, displaying the cursor image 18 at the current position, and depressing a key on the displayed keyboard image 17. A coloring process is performed on the designated key.
[0037]
FIG. 19 is a diagram showing a screen of a reproduction process in the two-hand part performance mode displayed on the display 6. On this screen, the designated playback icon 11 is displayed in color (hatched in the figure), and the current position of the musical score image 16 is clearly displayed by the cursor image 18 (hatched in the figure). Further, the key image 19 corresponding to the performance instruction is displayed in color on the keyboard image 17 (hatched in the figure).
[0038]
When the song for which the warning is displayed in step B34 of FIG. 7 is selected as it is, and the pitch of the song cannot be played in the key range of the keyboard image 17, the keyboard image 17 displayed on the screen of FIG. The key image of the highest key or the lowest key is displayed in a different color, and the performance of the key of the keyboard device 10 corresponding to the key image is instructed, and the timing of the musical score of the pitch displayed on the screen is performed. Alternatively, a performance lesson may be performed. In this case, it is desirable to instruct the sound source 8 to generate sound based on the pitch of music data corresponding to the musical score, not the key-on event input from the keyboard device 10 via the interface 7. Therefore, even when the musical pitch cannot be played in the key range of the keyboard image 17, the performance can be continued without a sense of incongruity.
[0039]
Next, it is determined whether or not the stop icon 12 has been designated (step C7). When this icon has been designated, it is determined whether or not the reproduction flag PF is "1 (reproduction state)" (step C7). C8). If the PF is "1 (reproduction state)", the PF is set to "0" (step C9), and a stop process is performed (step C10).
[0040]
In the flow of FIG. 9, it is determined whether or not the fast-forward icon has been designated (step C11). When this icon has been designated, it is determined whether or not the reproduction flag PF is "1" (step C12). . If the PF is "1 (reproduction state)", fast forward processing is performed (step C13). Further, it is determined whether or not the fast reverse icon is specified (step C14), and when this icon is specified, it is determined whether or not the reproduction flag PF is “1” (step C15). If the PF is "1", the fast rewind process is performed (step C16). That is, the fast-forward processing and the fast-reverse processing can be changed only during the reproduction of the music.
[0041]
After performing the reproduction process, the stop process, the fast-forward process, or the fast-reverse process, it is determined whether or not there is a key event of a key-on (key-press) or a key-off (key-release) from the keyboard device 10 via the interface 7. (Step C17). If there is no key event, this flow ends and the flow returns to the main flow. If there is a key event, it is determined whether the key event is a key-on event or a key-off event (step C18).
[0042]
In the case of a key-on event, the value obtained by multiplying the value of the register SFT by “12” is added to the key number of the key-on event, and the key image corresponding to the added value is colored in a color different from that of the performance instruction. At the same time, the sound source 8 is instructed to sound (step C19). When the key event is a key-off event, a value obtained by multiplying the value of SFT by “12” is added to the key number of the key-off event, and the color display of the key image corresponding to the added value is released, and 8 is instructed to mute (step C20). After the processing in step C19 or step C20, this flow ends and the flow returns to the main flow.
[0043]
As described above, according to this embodiment, the CPU 1 detects the key range of the keyboard device 10, detects the range of the music played by the keyboard device 10, and displays based on the detected key range and the range. A key area to be set is set, and a keyboard image for instructing the performance of a music piece is generated based on the set key area, and output to the display 6 for display. Therefore, it is possible to realize an appropriate performance lesson by using a keyboard image corresponding to the range of the music to be played and the key range to be used.
[0044]
In this case, since the CPU 1 detects the key range based on the lowest key and the highest key input by the key pressing operation of the keyboard device 10, even if the user is a small child, both ends of the keyboard of the keyboard device 10 are detected. It is only necessary to press a key or to press keys at both ends of a key range in which the user himself can play, so that the keyboard image 17 can be easily displayed and a performance lesson can be taken.
[0045]
Further, in this case, the CPU 1 sets the key range to be displayed in a state where the key range of the keyboard device 10 is shifted in octave units according to the range of the music, so that each of the keyboard image, the music, and the keyboard device 10 is set. And the key range of the keyboard image can be displayed very close to the key range of the selected music, and the actual key position of the keyboard device 10 and the key position of the key image displayed on the display 6 can be displayed. By matching, the consistency between the musical range of the musical score image and the key range of the keyboard image is enhanced for the user, and a performance lesson without discomfort can be performed.
[0046]
Further, in this case, the median value of the key range of the keyboard device 10 to be actually played is subtracted from the median value of the key range corresponding to the range of the selected music piece, and the subtraction result is calculated using the number of keys of one octave “12”. The divided value is rounded off, and based on the rounded value and its sign, the setting to shift the key range to be displayed in accordance with the detected range is performed. Therefore, the position and width of each range of the music and the keyboard device 10 are set. Even when the performances are different, it is possible to perform a consistent and comfortable training lesson.
[0047]
For example, it is assumed that the central key number in the key range of the keyboard device 10 is “60” (the pitch is “C3”). In this case, if the central pitch in the range of the selected song is “E4” and the corresponding key number is “76”,
(76-60) ÷ 12 = 1.33 ...
Is obtained. When this calculation result is rounded off, the value stored in the SFT becomes “1”. In this case, a key range in which the key range of the keyboard device 10 is shifted by one octave to the higher range is set, and the keyboard image is displayed below the score image on the screen of the display 6.
[0048]
Alternatively, when the central pitch in the range of the selected song is “A4” and the corresponding key number is “81”,
(81-60) ÷ 12 = 1.75
Is obtained. When this calculation result is rounded off, the value stored in the SFT becomes “2”. In this case, a key range in which the key range of the keyboard device 10 is shifted by two octaves to the higher range is set, and the keyboard image is displayed below the score image on the screen of the display 6.
[0049]
