A. First embodiment
(1) Configuration
FIG. 1 is a block diagram showing the overall configuration of the fingering candidate display device according to the first embodiment. The fingering candidate display device includes a data input unit 1, a display unit 2, a data designation unit 3, a CPU 4, a ROM 5, and a RAM 6. The data input unit 1 takes in music data generated by a fingering information generation device (not shown) and stores it in the RAM 6. As shown in FIG. 2, the music data is configured in the MIDI data format, and includes music data representing each sound constituting the music and fingering data for each sound. The song data represents the sound generation start time, sound generation time, and pitch for each event MidiEvent corresponding to each sound constituting the music.

  On the other hand, the fingering data has keyboard coordinates iPosx and fingering candidates cfigAlt [0] to cfigAlt [N] corresponding to the sound represented by the music data. The keyboard coordinate iPosx represents the keyboard position of the pitch (pitch) of the corresponding sound. The fingering candidates cfigAlt [0] to cfigAlt [N] represent fingering candidates corresponding to the sound represented by the song data. Note that the fingering referred to here indicates values (“0: thumb”, “1: index finger”, “2: middle finger”, “3: ring finger”, and “4: little finger”) representing the key to be operated. . Therefore, a maximum of five types of fingering candidates can be defined from one thumb to the little finger for one sound. As will be described later, fingering candidates cfigAlt [0] to cfigAlt [N] assigned to each sound are designated by a pointer i. The fingering candidates for each sound specified by the pointer i are collectively referred to as a fingering sequence.

  Under the control of the CPU 4, for example, as shown in FIG. 4, the display unit 2 displays music data based on the music data described above, and designates a display range of fingering candidates on the displayed music score. A fingering display screen UG or the like is displayed. The data designating unit 3 includes an input device such as a mouse or a keyboard, and displays a fingering candidate display range (start sound and end sound) in the fingering display screen UG displayed on the display unit 2 (see FIG. 4). Click the corresponding “click event” by clicking the “candidate 1” to “candidate 3” buttons for designating or clicking the “multiple candidate generation buttons” arranged on the screen UG and the fingering candidate display switching. appear. The CPU 4 controls each part of the apparatus, and processing operations related to the gist of the present invention will be described in detail later.

  The ROM 5 stores various control programs and tables that are loaded into the CPU 4. The various control programs referred to here include a main routine and an evaluation process described later. The ROM 5 is provided with a cost table cCostTwoFinger. The cost table cCostTwoFinger is a table that reads out an evaluation value representing the ease of fingering assigned to the current evaluation target sound, taking into account two adjacent sounds, that is, the current evaluation target sound and the next sound. It is. Specifically, iBW indicating whether the black key / white key is different, iPM indicating whether the next sound is the high-frequency side or the low-frequency side of the current evaluation target sound, and the fingering c fig assigned to the current evaluation target sound , ITt representing the fingering cfig assigned to the next sound, and an evaluation value corresponding to the separation distance iInt between the keyboard position of the currently evaluated sound and the keyboard position of the next sound are registered. Further, the ROM 5 stores various image data constituting the fingering display screen UG shown in FIG.

  The RAM 6 includes a data area and a work area. In the data area of the RAM 6, music data taken in via the data input unit 1 is stored. In the work area of the RAM 6, various registers and flag data used in the main routine executed by the CPU 4 and evaluation processing are temporarily stored.

(2) Operation Next, the operation of the first embodiment will be described with reference to FIGS. In the following, the operation of the main routine will be described on the assumption that the music data shown in FIG. 2 is stored in the data area of the RAM 6 via the data input unit 1, and then the operation of the evaluation process will be described.

<Main routine operation>
When the main routine shown in FIG. 3 is executed in response to the power-on of the apparatus, the CPU 4 proceeds to step SA1, reads the image data stored in the ROM 5, and displays the fingering display screen UG shown in FIG. After the screen is displayed on the display unit 2, pointers for designating the start sound and the end sound set by the user in the score displayed on the fingering display screen UG are pointers mef (start sound) and met (end sound). To store.
Next, in step SA2, the process waits until the “multiple candidate generation button” arranged on the fingering display screen UG is clicked. When the button is clicked, the determination result is “YES”. Proceed to SA3. In step SA3, the pointer i designating the fingering sequence and the pointer k designating the buffer Buf [k] holding the evaluation value costs of the fingering sequence are each reset to zero.

  Subsequently, in step SA4, it is determined whether or not the value of the pointer i has reached N, that is, whether or not all the fingering sequences have been evaluated. If the evaluation has not been completed, the determination result is “NO”, and an evaluation process (described later) is executed via step SA5 to obtain an evaluation value costs (described later) of the fingering sequence designated by the pointer i. In step SA6, whether or not the evaluation value costs obtained in the evaluation process in step SA5 is not the prohibited value NOT_PERMIT and is equal to or less than the evaluation value costs of the previously evaluated fingering sequence stored in the register iCbuf. That is, it is determined whether the fingering sequence evaluated this time is easier to play than the fingering sequence evaluated last time. If the fingering sequence evaluated last time is easier to play, the determination result is “NO”, the process proceeds to step SA7, the pointer i designating the fingering sequence is incremented and stepped, and then the above-described steps. Return the process to SA4.

  On the other hand, if the fingering sequence evaluated this time is easier to play than the fingering sequence evaluated last time, the determination result in step SA6 is “YES”, the process proceeds to step SA8, and the buffer Buf specified by the pointer k is displayed. In [k], the fingering series evaluated this time and the evaluation value costs are stored. Next, in step SA9, the pointer k is incremented, and in the subsequent step SA10, the evaluation value costs of the fingering sequence evaluated this time is stored in the register iCbuf and updated to the previous value, while the pointer i is incremented. The process returns to step SA4.

Thereafter, the above-described steps SA4 to SA10 are repeated until all fingering sequences have been evaluated. As a result, each time the pointer i is incremented, the evaluation value of the fingering sequence evaluated last time is compared with the evaluation value evaluated this time, and the fingering sequence that is easier to play and its evaluation value costs are stored in the buffer Buf [k]. Stored in When all the fingering sequences have been evaluated, the determination result in step SA4 is “YES”, and the process proceeds to step SA11 to display the fingering sequence.
In the fingering sequence display, the contents of the buffer Buf [k] are rearranged in the order from the smallest evaluation value costs, that is, in the order in which it is easy to play, and the rearranged order indicates, for example, display switching of fingering candidates. Assigned to each button of “candidate 1” to “candidate 3”. For example, when the user clicks the “candidate 1” button arranged on the fingering display screen UG, the fingering sequence of “candidate 1” is read from the buffer Buf [k] and illustrated in FIG. Thus, the fingering from the start sound to the end sound is displayed in the fingering display part UGA of the fingering display screen UG.

<Operation of evaluation process>
Next, the operation of the evaluation process will be described with reference to FIG. When this process is executed through step SA5 (see FIG. 3) of the main routine described above, the CPU 4 proceeds to step SB1 shown in FIG. 6, resets the registers costs to zero, and starts the start sound of the pointer mef. Is stored in the pointer me so as to be set as the evaluation target sound. Subsequently, in step SC2, the fingering candidate me [cfigAlt [i]] of the evaluation target sound is stored in the register iFt, the keyboard coordinates me [iPosx] of the evaluation target sound is stored in the register iFp, and the evaluation target sound is a black key / white key. The value me [iPosx]% 2 (2 remainder value of the keyboard coordinate 2 of the evaluation target sound) is stored in the register iBW. Note that me [iPosx]% 2 represents a white key when “0” and a black key when “1”.

Next, in step SB3, a pointer for designating the next sound me [next] of the evaluation target sound is set in the pointer men. In step SB4, the fingering candidate men [cfigAlt [i]] of the next sound designated by the pointer men is stored in the register iTf, and the keyboard coordinates men [iPosx] of the next sound are stored in the register iTp.
Subsequently, in step SB5, the keyboard coordinates of the evaluation target sound stored in the register iFp are compared with the keyboard coordinates of the next sound stored in the register iTp, and if iFp <iTp, “0” is set, iFp ≧ If iTp, “1” is stored in the register iPM. That is, a value of “0” is stored in the register iPM if the next sound is higher than the evaluation target sound, and “1” is stored otherwise. In Step SB5, the distance (iTp-iFp or iFp-iTp) between both keys is stored in the register iInt from the keyboard coordinates of the evaluation target sound and the keyboard coordinates of the next sound.

In step SB6, according to each value of the registers iBW, iPM, iFt, iTt, iInt obtained in steps SB2 to SB5, the fingering sequence i assigned to the evaluation target sound from the cost table cCostTwoFinger stored in the ROM 5 is obtained. An evaluation value iCost representing the ease of fingering is read for the fingering candidates. Next, in step SB7, the fingering candidates of the fingering sequence i assigned to the evaluation target sound are “no thumb or little finger assigned to the black key fingering”, “fingering reversal during chord” and “fingering” It is determined whether or not any of the prohibition conditions “not exceeding the possible width” is met. If any of the prohibition conditions is satisfied, the determination result is “YES”, the process proceeds to step SB8, the prohibition value NOT_PERMIT is stored in the register costs, and the present process ends.
When the prohibition value NOT_PERMIT is stored in the register costs, the determination result in step SA6 (see FIG. 3) of the main routine is “NO”, and the corresponding fingering sequence i is excluded from the comparison target. It has become.

  On the other hand, if the fingering candidate of the fingering sequence i assigned to the evaluation target sound does not meet the prohibition condition, the determination result in Step SB7 is “NO”, and the flow proceeds to Step SB9. In step SB9, the evaluation value iCost obtained in step SB6 is stored in a register me [iCost] that temporarily stores the evaluation value of the evaluation target sound designated by the pointer me. Subsequently, in step SB10, the value of the register me [iCost] is added to the register costs to accumulate the evaluation value costs of the fingering sequence i.

  Next, in step SB11, it is determined whether or not the pointer me matches the pointer met designating the end sound, that is, whether or not all the fingering candidates from the start sound to the end sound in the fingering sequence i have been evaluated. . If the evaluation has not been completed, the determination result is “NO”, the process proceeds to step SB12, the pointer me is incremented to move the evaluation target sound to the next sound, and then the process returns to step SB2. Thereafter, the above steps SB2 to SB12 are repeated until evaluation is completed for all fingering candidates of the fingering sequence i in the music range from the start sound to the end sound designated by the user. When the evaluation is completed for all fingering candidates, the determination result in step SB11 is “YES”, and the process is completed.

  As described above, in the first embodiment, when the user designates a song range from the start sound to the end sound from among the music data having a plurality of fingering candidates for each sound constituting the music, the music is designated. The sound from the start sound to the end sound is changed as the evaluation target sound, and the evaluation value iCost of the fingering candidate of the evaluation target sound determined according to the relationship between the evaluation target sound and the next sound is accumulated, An evaluation value costs is generated. Such fingering series evaluation values costs are obtained for a plurality of series corresponding to a plurality of fingering candidates. Each time the evaluation value costs is generated, it is compared with the previous evaluation value costs, and the fingering sequence whose value is easier to play and the evaluation value costs are stored in the buffer Buf [k], and all the fingering sequences are evaluated. Since the fingering sequences are displayed in the order in which they are easy to play among the fingering sequences stored in the buffer Buf [k] at the time of completion, it is possible to present a plurality of different fingerings within a specified range in the song. ing.

B. Second Embodiment Next, the operation of the second embodiment will be described with reference to FIGS. The second embodiment is different from the first embodiment described above in that the user designates one arbitrary sound in a song and designates a predetermined number of sounds before and after the designated sound. is there. The operations of the “main routine” and “range evaluation process” according to the first embodiment will be described below. Note that the “evaluation process” of the second embodiment is the same as that of the first embodiment described above, and a description thereof will be omitted.

<Main routine operation>
When the main routine shown in FIG. 7 is executed in response to the turning on of the apparatus power, the CPU 4 executes a range specifying process via step SC1. In the range designating process, as will be described later, various image data stored in the ROM 5 are read out and the fingering display screen UG shown in FIG. 4 is displayed on the display unit 2, and then a score is displayed on the fingering display screen UG. When the user designates an arbitrary one of the sounds to be played, the range is designated for a predetermined number of sounds before and after the designated sound, the start sound of the range is designated as the pointer mef, and the end sound is designated as the pointer met. It is supposed to store.

  Next, in step SC2, the process waits until the “multiple candidate generation button” arranged on the fingering display screen UG is clicked, and when the button is clicked, the determination result is “YES”. Proceed to SC3. In step SC3, the pointer i designating the fingering sequence and the pointer k designating the buffer Buf [k] holding the evaluation value cost of the fingering sequence are each reset to zero.

  Subsequently, in step SC4, it is determined whether or not the value of the pointer i has reached N, that is, whether or not all the fingering sequences have been evaluated. If the evaluation has not been completed, the determination result is “NO”, and the above-described evaluation process (see FIG. 6) is executed via step SC5 to obtain the evaluation value costs of the fingering sequence designated by the pointer i. In step SC6, whether or not the evaluation value costs obtained in the evaluation process in step SC5 is not the prohibition value NOT_PERMIT and is equal to or less than the evaluation value costs of the previously evaluated fingering sequence stored in the register iCbuf. That is, it is determined whether the fingering sequence evaluated this time is easier to play than the fingering sequence evaluated last time. If the fingering sequence evaluated last time is easier to play, the determination result is “NO”, the process proceeds to step SC7, the pointer i designating the fingering sequence is incremented and stepped, and then the above-described step Return processing to SC4.

  On the other hand, if the fingering sequence evaluated this time is easier to play than the fingering sequence evaluated last time, the determination result in step SC6 is “YES”, the process proceeds to step SC8, and the buffer Buf specified by the pointer k is displayed. In [k], the fingering series evaluated this time and the evaluation value costs are stored. Next, in step SC9, the pointer k is incremented, and in the subsequent step SC10, the evaluation value costs of the fingering sequence evaluated this time is stored in the register iCbuf and updated to the previous value, while the pointer i is incremented. The process returns to step SC4 described above.

  Thereafter, the above-described steps SC4 to SC10 are repeated until all the fingering sequences have been evaluated. As a result, each time the pointer i is incremented, the evaluation value of the fingering sequence evaluated last time is compared with the evaluation value evaluated this time, and the fingering sequence that is easier to play and its evaluation value costs are stored in the buffer Buf [k]. Stored in Then, when all the fingering sequences have been evaluated, the determination result in step SA4 is “YES”, the process proceeds to step SC11, and the fingering sequence display is performed as in the first embodiment described above.

<Operation of range specification processing>
Next, the operation of the range specifying process will be described with reference to FIG. When this process is executed via step SC1 (see FIG. 7) of the main routine, the CPU 4 advances the process to step SD1 shown in FIG. In step SD1, it waits until the user designates (clicks on) a desired sound meA among the sounds displayed on the score on the fingering display screen UG (see FIG. 4). When the sound meA is designated, the determination result is “YES”, and the process proceeds to Step SD2. In step SD2, a pointer that specifies the sound meA [prev] immediately before the user-specified sound meA is stored in the register metmp, and a counter iCnt that counts the number of notes is reset to zero.

  Subsequently, in step SD3, it is determined whether or not the sound designated by the register metmp is not at the beginning of the song and the value of the counter iCnt is smaller than the number of notes iNoteCnt. The number of notes iNoteCnt is a preset number of notes. Accordingly, in this step SD3, it is determined whether or not the first sound in the range separated from the user-specified sound meA by the number of notes iNoteCnt has been reached. If the sound at the head of the range has not been reached, the determination result is “YES”, the process proceeds to step SD4, and the pointer stored in the register metmp is set to the pointer mef. Next, in step SD5, a pointer for specifying the sound mef [prev] immediately before the sound specified by the pointer mef is stored in the register metmp. In step SD6, the counter iCnt is incremented in accordance with the advance of the sound by one step, and then the process returns to step SD3.

  Thereafter, steps SD3 to SD6 are repeated, and the sound is advanced by one note to the beginning of the range separated from the user-specified sound meA by the number of notes iNoteCnt. When the first sound in the range separated from the user-specified sound meA by the number of notes iNoteCnt is reached, the determination result in step SD3 is “NO”, and the process proceeds to step SD7. At this time, the pointer mef becomes a pointer for designating the sound at the head of the range. Subsequently, in step SD7, a pointer for specifying the sound meA [next] immediately after the user-specified sound meA is stored in the register metmp, and the counter iCnt for counting the number of notes is reset to zero.

  Next, in step SD8, it is determined whether or not the sound designated by the register metmp is not the music end END and the value of the counter iCnt is smaller than the number of notes iNoteCnt. Therefore, in step SD8, it is determined whether or not the sound has reached the rear end of the range separated from the user-specified sound meA by the number of notes iNoteCnt. If the sound at the end of the range has not been reached, the determination result is “YES”, the flow proceeds to step SD9, and the pointer stored in the register metmp is set to the pointer met. Next, in step SD10, a pointer that specifies the sound met [next] immediately after the sound specified by the pointer met is stored in the register metmp. In step SD11, the counter iCnt is incremented in response to the sound being advanced one step later, and then the process returns to step SD8.

  Thereafter, steps SD8 to SD11 are repeated, and the sound is advanced by one sound to the sound at the rear end of the range separated from the user-specified sound meA by the number of notes iNoteCnt. When the sound at the rear end of the range separated from the user-specified sound meA by the number of notes iNoteCnt is reached, the determination result in step SD8 is “NO”, and this processing is terminated. When the determination result in step SD8 is “NO”, the pointer met is set to designate the sound at the end of the range.

  As described above, according to the second embodiment, the user designates one arbitrary sound in a song, and a range is designated for a predetermined number of sounds before and after the designated sound. As in the first embodiment, a fingering candidate for the evaluation target sound that is determined according to the relationship between the evaluation target sound and the next sound is changed from the start sound to the end sound in the specified range as the evaluation target sound. The evaluation value iCost is accumulated to generate an evaluation value costs of the fingering sequence, and the evaluation value costs of the fingering sequence is obtained for a plurality of sequences corresponding to a plurality of fingering candidates, and the evaluation value costs is generated. Compared with the previous evaluation value costs every time, the fingering sequence whose value is easier to play and the evaluation value costs are stored in the buffer Buf [k], and buffered when all the fingering sequences have been evaluated. Luck stored in Buf [k] Since the fingering sequences are displayed in the order in which they are easy to play, it is possible for the user to present a plurality of different fingerings within a song range determined by the user simply by specifying an arbitrary sound in the song. ing.

C. Third Embodiment Next, the operation of the third embodiment will be described with reference to FIG. The third embodiment is different from the second embodiment described above in that the data cTendency indicating the high and low tendency of the sound sequence (song data) is provided in the fingering data, and the user specified with reference to this data cTendency The purpose is to specify a range in which the pitch of the sound is switched before and after the sound. Hereinafter, the operation of the range specifying process according to the third embodiment will be described. Since the main routine of the third embodiment is the same as that of the second embodiment described above, the description thereof is omitted.

  As in the second embodiment described above, when this process is executed via step SC1 (see FIG. 6) of the main routine, the CPU 4 advances the process to step SE1 shown in FIG. In step SE1, it waits until the user clicks the desired sound meA among the sounds displayed on the score on the fingering display screen UG (see FIG. 4) and designates the sound. When the sound meA is designated, the determination result is “YES”, and the flow proceeds to step SE2. In step SE2, a pointer for designating the sound meA [prev] immediately before the user-designated sound meA is stored in the register metmp. In step SE3, the pointer stored in the register metmp is set in the section head pointer mef.

  Subsequently, in step SE4, it is determined whether or not mef [cTendency], that is, the high and low tendency cTendency provided as the fingering data of the sound designated by the section start pointer mef is “0”. The high / low tendency cTendency is data representing the high / low tendency of the sound string (music data), and represents an extreme value (peak) when it is “0”. Therefore, in step SE4, it is determined whether or not the section head pointer mef is an extreme value. If the section head pointer mef is not an extreme value, the determination result is “NO”, the process proceeds to step SE5, the section head pointer mef is further advanced to the previous sound, and the process returns to step SE3. Thereafter, the section head pointer mef is advanced until a sound having an extreme value cTendency is found, and when a sound having an extreme value cTendency is found and the sound at the section top is determined, the determination result in step SE4 is determined. "YES" is determined, and the process proceeds to Step SE6.

  In step SE6, a pointer for specifying the sound meA [next] immediately after the user-specified sound meA is stored in the register metmp. Next, in step SE7, the pointer stored in the register metmp is set to the section rear end pointer met. Subsequently, in step SE8, met [cTendency], that is, whether or not the tendency cTendency of the fingering data of the sound specified by the section trailing end pointer mef is “0”, that is, specified by the section trailing end pointer met. Determine if the sound is extreme. If the sound of the section rear end pointer met is not an extreme value, the determination result is “NO”, the process proceeds to step SE9, the section rear end pointer met is further advanced to the next subsequent sound, and the process returns to step SE7. .

Thereafter, the section rear end pointer met is advanced until a sound having an extreme value cTendency is found. When a sound having an extreme value cTendency is found and the sound at the end of the section is determined, the determination result of step SE8 is determined. Becomes “YES”, and this processing is completed.
As described above, in the range specifying process according to the third embodiment, a range of sound train segments in which the pitch of sound is switched before and after the user-specified sound meA can be specified, so that a plurality of musically natural fingering sequences can be presented. It is like that.
