The data area of the ROM 12 stores musical score display data for displaying notes, rests, staffs, and various screen data for forming a GUI screen.

  The RAM 13 includes a work area and a data area. In the work area of the RAM 13, various register / flag data used for the processing of the CPU 11 are temporarily stored. The data area of the RAM 13 is composed of a song data area and a score information area. The song data area of the RAM 13 stores song information for a plurality of songs. As shown in FIG. 2, the song information is composed of a plurality of performance tracks [0] to [N] corresponding to performance parts. One performance track has music data [0] to [N] representing each sound forming a corresponding performance part, and has END data representing the end of the music at the end. The song data is composed of a sound generation start time ITime, a pitch lGate, a pitch Pitch, and a pointer pNext for designating the next song data, which are expressed as elapsed time (absolute time) from the performance start time.

  The musical score information area of the RAM 13 is generated by musical note data [0] to [N] derived from the above-mentioned music piece data [0] to [N] by musical score information generation processing described later and by setting processing described later. Meta information is stored. As shown in FIG. 3, note data [0] to [N] generated corresponding to the song data [0] to [N] includes a pointer next, a pointer prev, a pointer mEvent, a pronunciation start time ITime, and a measure. It is composed of a number sMeas, a beat number sBeat, coordinates (ix, iy), a note type cNoteType, a code cChord, a beam pattern start point cRenKouS, a beam pattern end point cRenKouE, a line number cLine, and a crossover flag cDanCross.

The interface (I / F) unit 17 includes a MIDI interface that exchanges music data in the MIDI format with an external MIDI device under the control of the CPU 11. Although not shown in FIG. 1, when a keyboard device is connected as an external MIDI device to the MIDI interface of the interface (I / F) unit 17, it occurs corresponding to a key release operation of the keyboard device. The song data is stored in the song data area of the RAM 13 via the MIDI interface.

B. Operation Next, the operation of the embodiment having the above-described configuration will be described with reference to FIGS. In the following, first, the operation of the main routine will be described as the overall operation, and then each operation of the score information generation processing, score display processing, and setting processing called from the main routine will be described.

(1) Operation of main routine In response to turning on the power of the apparatus, the CPU 11 executes the main routine shown in FIG. 4 and proceeds to step SA1 to reset various registers / flags provided in the work area of the RAM 13. Or perform initialization to set the initial value. Thereafter, the process proceeds to step SA2 to wait for a key operation input by the user. In steps SA3 to SA5, it is determined whether or not there is a key operation input instructing execution of “song selection”, “setting”, and “playback” while waiting for a key operation input.

  When a key operation input for instructing “song selection”, that is, any one of a plurality of pieces of song information stored in the song data area of the RAM 13 is selected, the determination result in step SA3 becomes “YES”, and step SA6 is performed. After the score information generation process (described later) is executed, a score display process (described later) is executed via step SA9. Then, the process returns to the above-described step SA2 to return to the key operation input waiting state.

  When a key operation input for instructing “setting” is performed, the determination result in step SA4 is “YES”, and a setting process (described later) is executed via step SA7. In the setting process, bar information for displaying the music data selected as a musical score is set. The bar information is information that specifies, for example, a clef, a time signature, and a key, and also specifies each bar position and each column position of music data selected for the music. Also, in the setting process, the quantization is set in units of measures to set the resolution to the user's preference, or the fingering information and the lyric information are set in correspondence with the note data derived from the song data. . After such setting processing is executed, musical score display processing (described later) is executed via step SA9, and then the processing returns to step SA2 described above to return to a key operation input waiting state.

  When a key operation input for instructing “play” is performed, the determination result in step SA5 is “YES”, and the process proceeds to step SA8. In step SA8, a reproduction process for reproducing the music data selected in step SA3 is executed. Thereafter, a score display process (described later) is executed through step SA9, and then the process returns to step SA2 to return to the key operation input waiting state.

(2) Operation of Score Information Generation Processing Next, the operation of score information generation processing will be described with reference to FIG. When this process is executed through step SA6 (see FIG. 4) of the main routine described above, the CPU 11 advances the process to step SB1, and selects the selected song information, that is, song data [0] to [0] for each performance track. [N] is subjected to a known quantization (time-axis quantization). By the quantize, the deviation of the sound generation start time ITime of the music data [0] to [N] is corrected. In step SB2, the track pointer Trptr for designating the performance track is reset to zero.

  Subsequently, in steps SB3 to SB8, the track pointer Trptr is incremented until all performance tracks have been designated, and “individual information generation” is performed on the music data of the performance track designated by the incremented track pointer Trptr. Processing (step SB4) "," chord processing (step SB5) "," digit group processing (step SB6) "and" digit processing (step SB7) "are performed. When all the performance tracks have been processed and the value of the track pointer Trptr advanced in step SB8 becomes end, the determination result in step SB3 is “YES”, and this processing is completed.

(3) Operation of Individual Information Generation Process Next, the operation of the individual information generation process will be described with reference to FIG. When this process is executed through step SB4 (see FIG. 5) of the musical score information generation process described above, the CPU 11 proceeds to step SC1 shown in FIG. 6 and designates song data [0] to [N]. The note pointer nptr to be reset is reset to zero. Subsequently, in step SC2, it is determined whether or not the music data [nptr] specified by the note pointer nptr has reached the music end end. If the song end end has not been reached, the determination result is “NO”, and the flow proceeds to step SC3.

  In step SC3, the sound start time ITime in the music data [nptr] currently specified by the note pointer nptr is added to the sound length lGate, and the sound generation in the next music data [pNext] specified by the pointer pNext is started. It is determined whether or not a rest is necessary from the time difference from the time ITime. If a rest is necessary, the determination result is “YES”, the process proceeds to step SC4, a rest corresponding to the time difference obtained in step SC3 is determined, and in step SC5, a bar for displaying the determined rest is displayed. After the display position is determined, the process proceeds to step SC6.

  On the other hand, if a rest is not necessary, the determination result in step SC3 is “NO”, and the flow proceeds to step SC6. In step SC6, a note type cNoteType (note type) corresponding to the tone length lGate in the music data [nptr] currently designated by the note pointer nptr is determined. In step SC7, the display position in the measure for displaying the determined note type cNoteType (note type) is determined. In step SC8, other supplementary information is set, such as connecting the next note with a tie. Next, in step SC9, after the note pointer nptr is incremented, the process returns to step SC2. Thereafter, steps SC2 to SC9 are repeated until the note pointer nptr reaches the song end end. When the note pointer nptr reaches the song end end, the determination result at step SC2 is “YES”, and this process ends.

(4) Operation of Chord Processing Next, the operation of the chord processing will be described with reference to FIG. When this processing is executed through step SB5 (see FIG. 5) of the musical score information generation process described above, the CPU 11 proceeds to step SD1 shown in FIG. 7 and designates song data [0] to [N]. The note pointer nptr to be reset is reset to zero. Subsequently, in step SD2, “0” is set to a flag InChord indicating the presence / absence of chord detection to indicate an undetected state. Next, in step SD3, it is determined whether or not the music data [nptr] specified by the note pointer nptr has reached the music end end. If the song end end has not been reached, the determination result is “NO”, and the process proceeds to step SD4.

  In step SD4, the sound generation start time ITime in the music data [nptr] currently specified by the note pointer nptr and the sound generation start in the next music data [pNext] specified by the pointer pNext in the music data [nptr] It is determined whether or not the time ITime is the same. In the following, description of the operation will be made separately for the case where the next sound generation time is the same and the case where it is not.

<When the next sound is played at the same time>
If it is the same as the sounding time of the next sound, the determination result in step SD4 is “YES”, and the flow proceeds to step SD5. In step SD5, it is determined whether the above-described flag InChord is “0”, that is, whether or not a chord is not detected. If the chord is not detected, the determination result is “YES”, the process proceeds to step SD7, and the code cChord in the note data [nptr] derived corresponding to the music data [nptr] specified by the note pointer nptr The value “1” representing the chord start sound is stored. Next, in step SD8, “1” is set to the flag InChord with the detection of the chord. Then, the process proceeds to step SD9, the note pointer nptr is incremented and stepped, and then the process returns to step SD3 described above.

  On the other hand, if the chord has already been detected, the determination result in step SD5 is “NO”, and the process proceeds to step SD6. In step SD6, the value “2” representing the halftone of the chord is stored in the code cChord in the note data [nptr] derived corresponding to the music data [nptr] specified by the note pointer nptr. Then, the process proceeds to step SD8, and after setting the flag InChord to “1”, the note pointer nptr is incremented in step SD9, and then the process returns to step SD3 described above.

<If it is not the same time as the next sound>
If it is not the same as the sounding time of the next sound, the determination result in step SD4 is “NO”, and the process proceeds to step SD10. In step SD10, it is determined whether or not the flag InChord is “1”, that is, whether the chord is being detected. If it is in the chord detection state, the determination result is “YES”, the process proceeds to step SD11, and the code cChord in the note data [nptr] derived corresponding to the music data [nptr] specified by the note pointer nptr is A value “3” representing the chord end sound is stored. In step SD13, the flag InChord is reset to zero. In step SD9, the note pointer nptr is incremented and stepped, and then the process returns to step SD3.

  On the other hand, if the chord is not detected, the determination result in step SD10 is “NO”, and the process proceeds to step SD12. In step SD12, a value “0” representing a non-chord is stored in the code cChord in the note data [nptr] derived corresponding to the music data [nptr] specified by the note pointer nptr. In step SD13, the flag InChord is reset to zero, and then the note pointer nptr is incremented in step SD9, and then the process returns to step SD3. Thereafter, the processing after step SD3 is repeated until the note pointer nptr reaches the song end end. When the stepped note pointer nptr reaches the song end end, the determination result at step SD3 becomes “YES”. Finish.

(5) Operation of Beam Digit Group Processing Next, the operation of beam digit group processing will be described with reference to FIG. When this process is executed through step SB6 (see FIG. 5) of the musical score information generation process described above, the CPU 11 advances the process to step SE1 shown in FIG. 8 and designates song data [0] to [N]. The note pointer nptr to be reset is reset to zero. Subsequently, in step SE2, music data [nptr] designated by the note pointer nptr is stored in the register vn. Next, in step SE3, it is determined whether or not the music data [nptr] specified by the note pointer nptr has reached the music end end. If the song end end has not been reached, the judgment result is “NO”, and the flow proceeds to step SE4.

  In step SE4, it is determined whether or not the music piece data [nptr] stored in the register vn satisfies the first note condition that is the first note of the consecutive digits. The leading sound condition here is a note length without a flag (tail) of the immediately preceding sound, that is, a quarter note length or more, and a sound to be determined this time is an eighth note length with a flag or less. Refers to that. If such a head sound condition is not satisfied, the determination result here is “NO”, and the flow proceeds to step SE12. In step SE12, a pointer for designating a sound to start searching for the beam start sound is set in the note pointer nptr. That is, when the process proceeds to step SE12 without satisfying the head sound condition, the note pointer nptr is incremented to designate the next sound, and then the process returns to step SE2.

  Then, it is assumed that the music piece data [nptr] specified by the stepped note pointer nptr does not reach the music end point end, and satisfies the condition that it becomes the leading sound of the consecutive digits. Then, the determination results in steps SE3 and SE4 are both “YES”, and the process proceeds to step SE5. In step SE5, the music piece data [nptr] stored in the register vn is stored in the continuous digit buffer.

  Subsequently, in step SE6, the next music piece data [pNext] specified by the pointer pNext in the music piece data [nptr] stored in the register vn is stored in the register vnx. Next, in step SE7, it is determined whether or not the song data [pNext] stored in the register vnx satisfies the continuous tone condition for the song data [nptr] stored in the register vn. The continuous tone condition indicates that both the immediately preceding and immediately following sounds and the current determination target sound have a note length with a flag. If this beam condition is satisfied, the determination result here is “YES”, and the flow proceeds to step SE8. In step SE8, the music piece data [pNext] stored in the register vnx is saved in the continuous buffer, and the music piece data [pNext] stored in the register vnx is stored in the register vn. Then, the process proceeds to step SE9.

  On the other hand, if the song data [pNext] stored in the register vnx does not satisfy the condition of consecutive to the song data [nptr] stored in the register vn, the determination result in step SE7 is “NO”. Thus, the process proceeds to step SE9. In step SE9, it is determined whether or not the music piece data [pNext] stored in the register vnx satisfies a beam end condition that becomes a beam end sound. The beam end condition indicates that both the immediately preceding sound and the sound to be determined this time have a note length with a flag, and the immediately following sound has a note length without a flag. If the beam end condition is not satisfied, the determination result is “NO”, and the process returns to step SE6.

  Thereafter, steps SE6 to SE9 are repeated until the sound that ends the beam is searched, the sound that is continued after the head tone of the beam is searched, and the corresponding sound (song data) is stored in the beam buffer. Save to. Then, when the sound at the end of the beam is searched, the determination result in step SE9 is “YES”, and the flow proceeds to step SE10. In step SE10, among the preset various beam patterns (beam patterns), a beam pattern suitable for the terminal tone is selected from the first sound of the beam stored in the beam buffer. In step SE11, a value representing the selected beam pattern is set in the beam pattern start point cRenkouS (see FIG. 3) in the note data corresponding to the first note of the beam stored in the beam buffer. Then, a value representing the selected beam pattern is set in the beam pattern end point cRenkouE (see FIG. 3) in the note data corresponding to the rear end sound of the beam stored in the beam buffer.

  Thereafter, the process proceeds to step SE12, and a pointer for designating a sound to start searching for the next beam start sound is set in the note pointer nptr. That is, in this case, after setting the pointer for designating the sound next to the trailing edge of the consecutive digits to the note pointer nptr, the process returns to step SE2. Thereafter, the above-described steps SE3 and after are repeated until the note pointer nptr reaches the music end end. Corresponding to the beam pattern start point cRenkouS and beam pattern end point cRenkouE for each beam group (a series of sound strings from the beam start sound to the end sound) found from the song data [0] to [N] When the setting of the note data to be completed is completed, the determination result in step SE3 is “YES”, and the present process ends.

(6) Operation of beam processing Next, the operation of beam processing will be described with reference to FIGS. When this process is executed through step SB7 (see FIG. 5) of the musical score information generation process described above, the CPU 11 advances the process to step SF1 shown in FIG. 9, and designates song data [0] to [N]. The note pointer nptr to be reset is reset to zero. Subsequently, in step SF2, the consecutive-digit flag InRenkou is reset to zero. The consecutive-digit flag InRenkou is a flag indicating whether or not the music data [nptr] specified by the note pointer nptr is a consecutive-digit sound. Represents a non-digit sound.

  In step SF3, it is determined whether or not the music data [nptr] specified by the note pointer nptr has reached the music end end. If the song end end has not been reached, the determination result is “NO”, and the process proceeds to step SF4. In step SF4 and after, according to the result of determining whether the music data [nptr] specified by the note pointer nptr is a non-continuous digit tone, a consecutive digit start tone, a tone in a consecutive digit, or a consecutive digit end tone. Execute the process. Hereinafter, the description of the operation is divided into processing for each case of a non-continuous digit tone, a consecutive digit start tone, a tone in the consecutive digits, and a consecutive digit end tone.

<For non-digit sounds>
A non-continuous sound refers to a sound that is not a target of a continuous beam. In the case of such a sound, the determination results of steps SF4, SF8, and SF9 described later are “NO”, and the process proceeds to step SF12 illustrated in FIG. 10 and the note pointer nptr is incremented and stepped. Then, the process returns to step SF3 shown in FIG.

<In the case of a beam start tone>
In step SF4, it is determined whether or not the music data [nptr] designated by the note pointer nptr is a continuous digit start sound. Specifically, it is determined whether or not a value representing the beam pattern is set at the beam pattern start point cRenkouS (see FIG. 3) in the note data corresponding to the music data [nptr] specified by the note pointer nptr. To do. If it is a consecutive digit start sound, the determination result in step SF4 is “YES”, the process proceeds to step SF5, and “1” is set to the consecutive flag flag InRenkou. Next, in step SF6, the note pointer nptr for designating the beam start sound is stored in the register vns. In step SF7, a register iSlopeAdj (hereinafter referred to as a beam slope correction value iSlopeAdj) for temporarily storing the beam slope correction value is reset to zero, and the process proceeds to step SF8 shown in FIG.

<For sounds in a beam>
In step SF8, it is determined whether or not the music data [nptr] designated by the note pointer nptr is a continuous digit end sound. Specifically, it is determined whether or not a value representing the beam pattern is set at the beam pattern start point cRenkouE (see FIG. 3) in the note data corresponding to the music data [nptr] specified by the note pointer nptr. To do. If the sound is not a continuous digit end sound but a continuous digit, the determination result is “NO” and the process proceeds to step SF9. In step SF9, it is determined whether or not the beam flag InRenkou is “1”, that is, whether or not the sound is in the beam.

  If it is a sound in a beam, the determination result here is “YES”, and the process proceeds to step SF10. In step SF10, it is determined whether or not the pitch difference with the next sound is positive. If the pitch difference with the next tone is positive, the determination result is “YES”, the process proceeds to step SF15, the beam slope correction value iSlopeAdj is incremented, then the process proceeds to step SF12, and the note pointer nptr is incremented. After stepping, the process returns to step SF3 in FIG.

  On the other hand, if the pitch difference from the next sound is not positive, the determination result in step SF10 is “NO”, and the flow proceeds to step SF11. In step SF11, it is determined whether or not the pitch difference with the next sound is negative. If the pitch difference with the next tone is negative, the determination result is “YES”, the process proceeds to step SF16, the beam slope correction value iSlopeAdj is decremented, and then the process proceeds to step SF12 to increment the note pointer nptr. After stepping, the process returns to step SF3 in FIG. On the other hand, if the pitch difference with the next sound is not negative, that is, if there is no pitch difference with the next sound, the determination result in step SF11 is “NO”, the process proceeds to step SF12, and the note pointer nptr is set. After incrementing and advancing, the process returns to step SF3 in FIG.

<In the case of a beam that ends the beam>
Now, when the music data [nptr] specified by the stepped note pointer nptr becomes a consecutive digit end sound, the judgment result of the above-mentioned step SF8 becomes “YES”, the process proceeds to step SF13 and the gradient of the consecutive digits is changed. calculate. The slope of the beam is calculated in consideration of the pitch difference between the beam start sound and the beam end sound and the beam slope correction value of the register iSlopeAdj. That is, in the string of consecutive digits, the consecutive slope correction value iSlopeAdj incremented or decremented according to the sign of the pitch difference between adjacent sounds is changed to the pitch difference between the consecutive digit start sound and the consecutive digit end sound. When the value obtained by multiplication is equal to or less than “0”, the gradient of the beam corresponding to the pitch difference between the beam start sound and the beam end sound is corrected by the beam gradient correction value iSlopeAdj. As a result, it is possible to obtain a beam with a natural slope by simple processing. The beam slope calculated in step SF13 is registered in the note data corresponding to each sound as attributes of the beam start sound and beam end sound.

  In step SF13, the gradient of the beam corresponding to the pitch difference between the beam start sound and the beam end sound is corrected by the beam gradient correction value iSlopeAdj. As a mode of calculating the slope of a beam by applying a least square approximation based on the pitch of each tone forming a beam group from the beam start sound to the beam end sound, it is possible to use a beam with a natural slope. Is possible.

  When the calculation of the beam slope is completed, the CPU 11 advances the process to step SF14, resets the beam flag InRenkou to zero, then advances to step SF12, increments the note pointer nptr, and advances the process in FIG. The process returns to step SF3. Thereafter, the processing after step SF3 is repeated until the music data [nptr] designated by the note pointer nptr reaches the music end end. When the song data [nptr] specified by the note pointer nptr reaches the song end end, the determination result in step SF3 is “YES”, and the process is terminated.

(7) Operation of Score Display Processing Next, the operation of the score display processing will be described with reference to FIGS. When the score display process is executed through step SA9 (see FIG. 4) of the main routine described above, the CPU 11 proceeds to step SG1 shown in FIG. 11 and draws a background image (stave score) on the display surface of the display unit 16. To do. Subsequently, in step SG2, a bar counter for counting the number of bars is initialized. Next, in step SG3, it is determined whether or not the value of the measure counter has reached the end end, that is, whether or not the musical score display has been completed for all the measures forming the song. If the score display has not been completed for all the bars, the determination result is “NO”, and the process proceeds to step SG4. In step SG4, for example, a clef, key, bar line, etc. are drawn on the staff based on the bar information specified by the bar counter value on the staff.

  In step SG5, the note pointer nptr for designating note data is reset to zero. Subsequently, in step SG6, it is determined whether or not the note pointer nptr has finished specifying a sound for one measure. If the sound for one measure has not been specified, the determination result is “NO”, the process proceeds to step SG7, and the display position of the note data currently specified by the note pointer nptr is calculated. Next, in step SG8, the note data currently designated by the note pointer nptr is drawn at the display position calculated in step SG7. Thereafter, the process proceeds to step SG9, the note pointer nptr is incremented, and the process returns to step SG6.

  In this way, when the display positions of the sounds forming the bars designated by the value of the bar counter are sequentially calculated, and when the notes are drawn at the display positions, the determination result at step SG6 is “YES”, and the step After proceeding to SG10 and incrementing the bar counter, the process returns to step SG3. Thereafter, the display position of the note is calculated for each measure, the notes corresponding to the calculated display position are drawn, and when the notes are drawn for all the measures, the determination result in step SG3 is “YES”. This processing is finished.

  It should be noted that when a note is drawn, an attribute included in the corresponding note data is referred to. The attributes included in the note data include the above-described note type cNoteType, the beam pattern pattern start point cRenkouS, and the beam pattern pattern end point RenkuE, as well as the beam gradient calculated in the beam pattern processing described above (see FIGS. 9 to 10). .

  FIG. 12 is a diagram showing an example of a score displayed on the screen by the score display process. FIG. 12A shows an example of a musical score in the case where correction of the beam slope by the beam processing described above is not performed. In this notation, the slope of the beam is not corrected, and the gradient of the beam is determined only by the pitch difference between the beam start sound and the beam end sound, which makes it uneven and difficult to see the notes in the beam. ing. On the other hand, FIG. 7B shows an example of a musical score in which the beam slope correction is performed by the beam processing described above. In this musical score example, the above-described correction does not cause the gradients of the beams to be uneven, so that the notes of the beams can be easily displayed.

(8) Operation of Setting Process Next, the operation of the setting process will be described with reference to FIGS. When the setting process is executed via step SA7 (see FIG. 4) of the main routine described above, the CPU 11 proceeds to step SH1 shown in FIG. 13 and displays the menu screen on the display unit 16. Here, an example of the menu screen will be described with reference to FIG. The menu screen illustrated in this figure includes an icon IC1 for instructing generation of measure information, an icon IC2 for instructing input of fingering information, an icon IC3 instructing input of lyrics information, an icon IC4 instructing quantization in units of measures, and It has an icon IC5 for instructing to save the set information. The icons IC <b> 1 to IC <b> 5 arranged on the menu screen are selected by a mouse operation (click) of the operation unit 10.

  When such a menu screen is displayed on the display unit 16, the CPU 11 proceeds to step SH2 and waits until an icon click operation is performed on the menu screen. When an icon click operation is performed on the menu screen, the determination result in step SH2 is “YES”, and the flow proceeds to step SH3. In steps SH3 to SH7, it is determined which of the icons IC1 to IC5 arranged on the menu screen has been clicked. That is, when the icon IC1 is clicked, the determination result in step SH3 is “YES”, and the process proceeds to step SH8 to specify the clef, time signature, key, and the song data of the selected song data. This processing is completed after executing the measure information generation processing for generating measure information for designating each measure position and each step position.

  When the icon IC2 is clicked, the determination result in step SH4 is “YES”, the process proceeds to step SH9, and after performing a fingering information input process described later, this process is finished. If the icon IC3 is clicked, the determination result in step SH5 is “YES”, the process proceeds to step SH10, and the lyrics information input process described later is executed, and then this process ends. When the icon IC4 is clicked, the determination result in step SH6 is “YES”, the process proceeds to step SH11, and after the measure quantizing process described later is executed, this process is finished. If the icon IC5 is clicked, the determination result in step SH7 is “YES”, the process proceeds to step SH12, and after executing a storage process to be described later, the present process ends.

The position coordinates (x, y) pointed by 10 mice are acquired. Next, at step SK2, the note pointer nptr for designating note data is reset to zero. Subsequently, in step SK3, it is determined whether or not the note pointer nptr has reached the song end end. If the song end end has not been reached, the determination result is “NO”, and the flow proceeds to step SK4.

  In step SK4, the mouse pointing coordinates (x, y) are compared with the coordinates (ix, iy) of the note data [nptr] specified by the note pointer nptr. In step SK5, the mouse is pointed to whether or not both coordinates (x, y) and (ix, iy) match, that is, the note head position of the note data [nptr] specified by the current note pointer nptr. Determine if you are. If the note head position is not pointed, the determination result is “NO”, the process proceeds to step SK6, the note pointer nptr is incremented and stepped, and then the process returns to step SK3.

  Thereafter, steps SK3 to SK6 are repeated until a note having the coordinate (ix, iy) of the note head that matches the position coordinate (x, y) pointed by the mouse is found. When a note having a note head coordinate (ix, iy) that matches the position coordinate (x, y) pointed by the mouse is found, the determination result in step SK5 is “YES”, and the process proceeds to step SK7. The pointer mEvent in the corresponding note data is stored in the register meorg, and this processing is finished. As a result, music data [meorg] corresponding to the note pointed with the mouse on the score displayed on the screen is designated. On the other hand, if the note pointer nptr reaches the end of music end without finding a note having the coordinate (ix, iy) of the note head that matches the position coordinate (x, y) pointed by the mouse, the above steps are performed. The determination result at SK3 is “YES”, the process proceeds to step SK8, the register meorg is reset to zero, and this process ends.

(10) Operation of fingering input process When this process is executed through the above-described step SJ2 (see FIG. 15), the CPU 11 proceeds to step SL1 shown in FIG. 17 and is input according to the user operation. The finger information is stored in the register cFig. The fingering information referred to here is specifically a finger number representing a finger to perform a key pressing operation. Next, in step SL2, the pointer mEvent stored in the register meorg is set to the pointer me designating music data. Therefore, the pointer me designates music data [me] corresponding to the note pointed with the mouse. In step SL3, the fingering information (finger number) of the register cFig is stored in the score information area (see FIG. 3) of the RAM 13 as meta information at the same timing as the sound generation start time lTime in the song data [me]. This process is finished.

(11) Operation of Lyric Information Input Process Next, the operation of the lyrics information input process will be described with reference to FIG. When the lyric information input process is executed through step SH10 (see FIG. 13) of the setting process described above, the CPU 11 executes the note point process (see FIG. 16) through step SM1 shown in FIG. On the displayed score, music data [meorg] corresponding to the note pointed with the mouse is designated. Then, the lyrics input process is executed via step SM2, and the present process is terminated.

(12) Operation of Lyric Input Processing When this processing is executed via the above-described step SM2 (see FIG. 18), the CPU 11 proceeds to step SN1 shown in FIG. 19 and lyrics information input in response to a user operation. (Character data) is stored in the register str. Next, at step SN2, the pointer mEvent stored in the register meorg is set to the pointer me designating the music piece data. Therefore, the pointer me designates music data [me] corresponding to the note pointed with the mouse. In step SN3, the lyrics information in the register str is stored in the score information area (see FIG. 3) of the RAM 13 as meta information at the same timing as the pronunciation start time lTime in the song data [me], and this processing is completed.

(13) Operation of Bar Quantize Processing Next, the operation of bar quantize processing will be described with reference to FIG. When the measure quantize process is executed through step SH11 (see FIG. 13) of the setting process described above, the CPU 11 executes the measure point process through step SP1 shown in FIG. Then, the quantizing process is executed via step SP2 to complete the present process.

(14) Operation of measure point processing When this processing is executed through the above-described step SP1 (see FIG. 20), the CPU 11 proceeds to step SQ1 shown in FIG. 21 and operates on the score displayed on the screen. The position coordinates (x, y) pointed by 10 mice are acquired. Next, in step SQ2, the bar counter is reset to zero. Subsequently, in step SQ3, it is determined whether or not the measure counter has reached the end measure at the end of the song. If the bar end is not reached, the determination result is “NO”, and the flow proceeds to step SQ4.

  In step SQ4, the pointing coordinate (x, y) of the mouse is compared with the coordinate (ix, iy) of the measure specified by the value of the measure counter. In step SQ5, it is determined whether or not both coordinates (x, y) and (ix, iy) match, that is, whether or not the position of the bar specified by the current bar counter value is pointed by the mouse. To do. If the bar position specified by the bar counter value is not pointed, the determination result is “NO”, the process proceeds to step SQ6, the bar counter is incremented and stepped, and the process proceeds to step SQ3 described above. To return.

  Thereafter, steps SQ3 to SQ6 are repeated until a bar having coordinates (ix, iy) matching the position coordinates (x, y) pointed by the mouse is found. When a bar with coordinates (ix, iy) matching the position coordinates (x, y) pointed with the mouse is found, the determination result at step SQ5 is “YES”, and the process proceeds to step SQ7. The measure number iMeasNo is stored in the register iCurMeas and the process is terminated. Thereby, the measure number iMeasNo of the measure pointed with the mouse on the score displayed on the screen is designated. On the other hand, when the measure having the coordinate (ix, iy) matching the position coordinate (x, y) pointed by the mouse is not found and the value of the measure counter reaches the measure end, the determination at step SK3 is made. The result is “YES”, the process proceeds to step SQ 8, “−1” is stored as the measure number in the register iCurMeas, and this processing is completed.

(15) Quantize Processing Operation Next, the quantization processing operation will be described with reference to FIG. When this process is executed via step SP2 (see FIG. 20) of the measure quantizing process described above, the CPU 11 proceeds to step SR1 shown in FIG. 22, and the quantization resolution specified by the user operation (for example, 16 minutes). Any one of note length, 32nd note length and 64th note length) is stored in the register iQ. Next, in step SR2, it is determined whether the measure is the quantized only for the pointed measure or whether it is quantized for the entire song depending on whether the measure number iMeasNo stored in the register iCurMeas is larger than a predetermined value in the measure point processing described above.

  Here, if the bar number iMeasNo stored in the register iCurMeas is larger than a predetermined value, that is, if the quantization is specified for the pointed bar, the determination result is “YES”, and the flow proceeds to step SR3. In step SR3, the user-specified resolution stored in the register iQ is stored in the register iBRResolution [iResolution] holding the resolution of the pointed measure, and the process is terminated. This makes it possible to change the resolution of a measure simply by pointing to the measure to be quantized.

  On the other hand, if the measure number iMeasNo stored in the register iCurMeas is smaller than 0, that is, if the quantization is specified for the entire song, the determination result in step SR2 is “NO”, and the process proceeds to step SR4. In step SR4, it is determined whether or not each value of the register iBRResolution [N] (N is 0 to n) that holds the resolution of each measure matches the current resolution iResolution of the entire song. If they match, the determination result is “YES”, the process proceeds to step SR5, and the user-specified resolution stored in the register iQ is stored in all the registers iBRResolution [N] holding the resolution of each measure. . Next, proceeding to step SR6, the user-specified resolution stored in the register iQ is stored in the current resolution iResolution of the entire tune, and this process is terminated.

  On the other hand, if the user-specified resolution stored in the register iQ does not match the current resolution iResolution stored in the register iOld, the determination result in step SR4 is “NO”, and the process proceeds to step SR7. In step SR7, the bar counter J is initialized. Next, in steps SR8 to SR11, a bar having the same resolution as that of the register iResolution is searched while incrementing the bar counter J until reaching the bar at the end of the song, and a register iBRResolution [J holding the resolution of the corresponding bar is searched. ] Stores the user-specified resolution stored in the register iQ. That is, since the measure determined as “NO” in SR9 is a measure in which the quantize of only the measure is changed after the quantize of the entire song is decided, it is excluded from the batch rewriting target. When the search is completed until the end of the song is reached, the determination result in step SR8 is “YES”, the process proceeds to step SR6, and the user-specified resolution stored in the register iQ is set to the current resolution iResolution of the entire song. Store and finish this process.

(16) Operation of Storage Process Next, the operation of the storage process will be described with reference to FIG. When this process is executed via step SH12 (see FIG. 13) of the setting process described above, the CPU 11 proceeds to step SS1 shown in FIG. 23 and initializes the register lPrevTime. Subsequently, in step SS32, it is determined whether or not the time stored in the register lPrevTime has reached the song end end. If the song end end has not been reached, the determination result is “NO”, and the process proceeds to step SS3. In step SS3, the type of data (note data or meta information stored in the score information area of the RAM 13) corresponding to the time stored in the register lPrevTime is checked.

  Next, in step SS4, the sound generation start time lTime of the data (note data or meta information) corresponding to the time stored in the register lPrevTime is stored in the register lCurTime. In step SS5, the time of the register lPrevTime is subtracted from the time of the register lCurTime to calculate the step time lStepTime. Next, in step SS6, the calculated step time lStepTime is stored. Next, in step SS7, it is determined whether or not the data type examined in step SS3 is note data.

  If it is note data, the determination result is “YES”, and the process proceeds to step SS8 to store the note data. On the other hand, if it is meta information, the determination result in step SS7 is “NO”, and the process proceeds to step SS9 to store the meta information. In step SS10, the value of the register lCurTime is updated to the register lPrevTime, and the process returns to step SS2. Thereafter, by repeating the above steps SS2 to SS10 until the time of the register lPrevTime reaches the end of music end, the note data and the meta information are stored in order of time, while the step time lStepTime corresponding to each data interval is also stored. It has become. Thus, when the time of the register lPrevTime reaches the song end end, the determination result in step SS2 is “YES”, and this processing is completed.

  As described above, in the present embodiment, in the score display device that converts the song data representing each sound constituting the song into score information to be displayed as a score and displays it on the screen, the measure specified in the displayed score is displayed. Is quantized to the resolution specified by the user, so that the score can be displayed at the resolution desired by the user by quantizing in units of measures. Also, because fingering information that represents the finger to be pressed is entered corresponding to the note specified in the displayed score, and lyrics are entered, fingering and lyrics other than notes are also displayed on the score.
