BACKGROUND OF THE INVENTION
The present invention relates to a voice assignment device, a voice assignment method, and a recording medium on which a voice assignment processing program is recorded.
[0002]
[Prior art]
Some automatic performance devices have a function of allocating lyrics to the melody of a song to be played and generating the sound of the lyrics along with the automatic performance. When lyrics are assigned to the melody, the notes of the performance music are displayed on the screen of the display device, and the lyric characters are assigned to each note. For example, in FIG. 17, “Kimi ga Boku” and one character are assigned to each note with respect to the five notes at the upper left of the drawing. In addition, when one letter “sa” is assigned to the last four notes in the upper right six notes in the figure to extend the pronunciation, the letter “sa” is assigned to the first note and the rest Each of the three notes is assigned a letter “A (A)” which is a vowel of the voice “SA (SA)” for each note.
[0003]
[Problems to be solved by the invention]
  However, in the conventional lyrics assignment technique, when one voice corresponds to a plurality of notes, the operation of assigning vowel characters to all the second and subsequent notes is complicated. Also, it was not possible to assign silence to notes that did not produce speech.
  The first problem of the present invention is to simplify the operation of assigning characters when one voice corresponds to a plurality of notes.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the voice allocation apparatus according to the present invention will be described.
FIG. 1 is a diagram illustrating a system configuration of a voice allocation device according to an embodiment. The CPU 1 exchanges commands and data with the keyboard 3, memory 4, display 5, and sound system 6 connected via the system bus 2 to control the entire apparatus.
[0017]
Although not shown in the figure, the keyboard 3 has a mode switching key for switching operation modes, a character key for inputting lyrics data, a symbol key, a numeric key, a space key, a delete key for erasing lyrics data, and a cursor. Cursor keys for moving are provided. The memory 4 includes a program area for storing a program executed by the CPU 1, a data area for storing voice waveform data, automatic performance data, and lyrics data, and other various register and flag areas necessary for executing the program.
[0018]
FIG. 2 is a diagram showing the contents of the data area of the memory 4. The voice waveform data stores PCM waveform data corresponding to the lyrics voice “A, I, U, E, O, Ka, Ki,...”. At the time of sound generation, the sound is read out at a reading speed corresponding to the pitch of the sound and sent to the sound system 6. The automatic performance data is composed of a combination of timing data and event data. The end of the automatic performance data is END data, and is configured to identify the end of the song. The key-on timing or key-off timing represents the time until the on event or the off event. The lyric data is composed of voice characters corresponding to the automatic performance music, symbols “+”, numerical values “2” to “9”, and spaces. The contents of lyric data and their roles will be described later.
[0019]
The display 5 in FIG. 1 displays an image of a cursor, which is an image that clearly shows the relationship between a musical score composed of notes and the like, lyrics, and lyric characters corresponding to the notes at the time of lyrics input processing and automatic performance processing described later. To do. Although not shown in the figure, the sound system 6 includes a sound source that generates an audio signal, a D / A converter that converts audio waveform data read from the memory 4 from a digital to an analog audio signal, and unnecessary components of the audio signal. A filter for removing, an amplifier for amplifying an audio signal, a speaker, and the like are provided. Then, sound generation is performed in accordance with the sound generation process and the voice waveform data from the CPU 1, and the sound is silenced in accordance with the mute process.
[0020]
Next, the operation of the voice assignment device shown in FIG. 1 will be described in detail based on the flowchart of the program executed by the CPU 1 and the content displayed on the screen of the display 5.
[0021]
FIG. 3 is a main flow of a program executed by the CPU 1. In this process, after the initialization process (step A1), automatic performance data is read from the memory (step A2), a score is created based on the data, and displayed on the display (step A3). Next, it is determined whether or not the lyric data corresponding to the automatic performance data exists in the memory (step A4). If there is lyrics data, the lyrics data is read (step A5), and the lyrics are displayed on the display in correspondence with the score (step A6). After the lyrics are displayed in step A6, or when there is no lyrics data corresponding to the score in step A4, the cursor is positioned at the head position across the score display area and the lyrics display area as shown in FIG. (Step A7). That is, an image that clearly shows the relationship between one note and the lyrics characters corresponding to the one note is displayed on the screen.
[0022]
Next, it is determined whether or not the mode switching key has been operated (step A8), and when operated, the mode flag is inverted (step A9). Also, both the addresses of the automatic performance data and the lyrics data are reset, the timer is reset, and the mute process is performed. If the cursor is not at the head position, the cursor moves to the head position (step A10). Then, it is determined whether the mode flag is “1” or “0” (step A11). When the mode flag is “1”, automatic performance processing is performed (step A12), and when the mode flag is “0”, lyrics input processing is performed (step A13). Next, other processing is performed (step A14). Then, the loop processing from step A8 to step A14 is repeatedly executed.
[0023]
In step A10, after resetting the timer, the timer interrupt processing routine shown in FIG. 5 is entered at regular intervals, the timer value is incremented (step B1), and the process returns to the main routine again. This timer value represents the passage of time of the automatic performance data in the case of the automatic performance processing in step A12 of FIG. 3, and it is determined whether or not the key-on timing and key-off timing have been reached by this timer value.
[0024]
Next, the lyrics input process in step A13 of the main flow of FIG. 3 will be described. The input lyric data is the “character” that is the target of the pronunciation voice, the “+” symbol that joins the letters, and the target when the voice is extended over a plurality of notes of the automatic performance data. It consists of a numerical value from “2” to “9” indicating the number of notes, and “space” in the case of a staccato that prohibits pronunciation or produces a short sound. When inputting the lyrics, as shown in FIG. 4, the cursor is displayed on the display screen at the position of the notes of the automatic performance data and the notes to which the lyrics are to be input, and the user inputs the lyrics while watching the screen. I do.
[0025]
6 to 9 are flowcharts of lyrics input processing, FIG. 10 is a diagram showing the relationship between automatic performance data and lyrics data, and FIGS. 11 to 14 are display examples according to the lyrics data to be input. FIG.
[0026]
In FIG. 6, it is determined whether or not the cursor position has been moved (step C1). If the operation of stepping up the cursor is performed, the type of lyrics data at the next address is determined (step C2). If the lyric data at the next address is characters, symbols, spaces, or if there is no lyric data, "4" is added to the address of the automatic performance data, and whether or not the data at that address is END data Is discriminated (step C3).
[0027]
For example, in FIG. 10A, when the cursor position is on the note n7, the cursor position cannot be advanced. That is, in this case, since the address of the automatic performance data is the address of the key-on timing data of n7 in FIG. 10 (B), when "4" is added to the address of the automatic performance data in step C3, it is added. The address data is END data. Therefore, when the added address data is END data, the cursor cannot be moved. On the other hand, if the added address data is not END data in step C3, the next address obtained by adding “4” to the current address for automatic performance data is designated as the address of the note to be moved by the cursor (step C4). .
[0028]
In step C2, if the lyrics data of the next address is a numerical value, a plurality of notes corresponding to the numerical value correspond to the lyrics of one character. In the example of FIG. 10A, the voice of the lyrics “ka” is assigned to three notes n2, n3, and n4. In this case, as shown in FIG. 10B, the address data from the key-on timing data n2 of the automatic performance data to the key-off event n4 for the character “ka” and the numerical value “3” of the lyrics data. Corresponds. Therefore, the address of the automatic performance data corresponding to the lyric data of the next address is an address obtained by adding a value obtained by multiplying the numerical value by “4” to the current address of the automatic performance data. In step C5 of FIG. 6, it is determined whether or not the automatic performance data at the next address is END data (step C5). When the data at the added address is END data, the cursor cannot be moved, so the cursor step operation is invalid, and other key inputs are discriminated. However, when the data at the added address is not END data, The next address obtained by adding the value obtained by multiplying the current address for automatic performance data by "4" to the numerical value is designated as the address of the note to be moved by the cursor (step C6).
[0029]
After the next address is designated in step C4 or step C6, it is determined whether or not there is lyrics data at the current address (step C7). If there is lyric data, the type of lyric data at the next address is determined (step C8). If the lyrics data at the next address is a numerical value, “2” is added to the address of the lyrics data (step C9), and the cursor position is incremented (step C10). For example, in the example of FIG. 10, when the lyrics data at the current address is the character “ka”, the lyrics data at the next address is the numerical value “3”. In this case, in step C9, “2” is added to the current address of the lyrics data to change the current address to the address of the character “NA”. Further, the current address of the automatic performance data is changed to the address of the key-on timing data of n5 by the process of step C6. Accordingly, the cursor position is changed to the position of the n5 note and the lyric character “NA” in FIG.
[0030]
In step C8, if the lyrics data at the next address is a symbol, "2" is added to the address of the lyrics data (step C11), and the type of the lyrics data at the next address of the added address is determined (step C11). Step C12). If the lyrics data at the next address is character, space, or lyrics data, “1” is further added to the address of the lyrics data (step C13). Then, the cursor position is incremented (step C10).
[0031]
For example, in FIG. 10B, when the lyrics data at the current address is “ha”, the lyrics data at the next address is the symbol “+”. In this case, "2" is added to the current address of the lyric data by the process of step C11 to set the address of the lyric data "ru" as the current address, and further, "1" is added to the current address by the process of step C13. ] Is added to the address of the lyrics data “ka”. Further, the cursor position is moved from the position of the n1 note in FIG. 10A to the position of the n2 note by the processing of step C10.
[0032]
If the lyric data at the next address is a symbol at step C12, “2” is added to the address of the lyric data again at step C11. For example, if three lyric characters “you” are assigned to one note of the automatic performance data, the lyric data includes the characters “A”, the symbol “+”, the character “NA”, and the symbol “N”. “+” And the letter “ta”. In this case, the address of the lyrics data is added by “4” by the processing of steps C11 and C12, and further, the address of the lyrics data is added by “1” in step C13.
[0033]
If there is no lyric data at the current address in step C7, or if the lyric data at the next address is a character or space in step C8, or if there is no lyric data, "1" is set in the address of the lyric data. Addition is performed (step C13), and the cursor position is incremented (step C10).
[0034]
If the cursor position movement operation is backward in step C1, it is determined whether or not the address of the automatic performance data is the head address (step C14). If it is the first address, the cursor position cannot be moved backward, so the cursor backward operation is invalid, and other key inputs are determined. If it is not the first address, the type of lyrics data at the previous address is determined. (Step C15). If there is no lyrics data at the previous address, “1” is subtracted from the current address of the lyrics data (step C16), and “4” is subtracted from the address of the automatic performance data (step C17). Then, the cursor position is moved backward (step C18).
[0035]
If the lyric data at the previous address is a character or a space at step C15, "1" is subtracted from the current address of the lyric data (step C19), and the type of the lyric data at the previous address is further determined (step C15). C20). If the lyrics data at the immediately preceding address is a symbol, “2” is subtracted from the current address of the lyrics data (step C21), and the type of the lyrics data is determined again at step C20. If the lyric data is a character or a space, “4” is subtracted from the current address of the automatic performance data (step C17). Then, the cursor position is moved backward (step C18).
[0036]
For example, in FIG. 10A, when the cursor position is on the note of n2, and the cursor position is moved backward, the lyrics data at the current address at that time is “ka” in FIG. The lyric data at the immediately preceding address is “RU”, and the lyric data at the immediately preceding address is the symbol “+”. In this case, “1” is subtracted from the address of the lyrics data in the process of step C19, the address of the lyrics data “ru” is made the current address, and “2” is subtracted from the address of the lyrics data in the process of step C17. Then, the address of the lyrics data “ha” is set as the current address. Then, the address of the automatic performance data is subtracted by “4” in the process of step C17. Therefore, in FIG. 10B, the address of the automatic performance data is changed from the key-on timing data of n2 to the address of the key-on timing data of n1. Further, the cursor position is moved backward from the position of the n2 note in FIG. 10A to the position of the n1 note in the process of step C18.
[0037]
In step C15, when the lyrics data at the previous address is a numerical value, "2" is subtracted from the current address of the lyrics data (step C22), and the numerical value is multiplied by "4" from the current address of the automatic performance data. The value is subtracted (step C23). Then, the cursor position is moved backward (step C18).
[0038]
For example, in FIG. 10A, when the cursor position is on the note of n5 and the cursor position is moved backward, the lyrics data at the current address at that time is “NA” in FIG. The lyric data at the immediately preceding address is the numerical value “3”. In this case, “2” is subtracted from the address of the lyrics data “NA” in the process of step C22, and the address of the lyrics data “KA” is made the current address. Further, the address of the automatic performance data is subtracted by “3 × 4 = 12” in the process of step C23, and in FIG. 10B, the address of the automatic performance data is changed from the key-on timing data of n5 to the key-on timing data of n2. Change to address. Further, the cursor position is moved backward from the position of the note n5 in FIG. 10A to the position of the note n2 in the process of step C18.
[0039]
After stepping the cursor position in Step C10, after moving the cursor position back in Step C18, or when there is no cursor moving operation in Step C1, or in Steps C3, C5, and C14, it is determined that the cursor moving operation is invalid If so, it is determined whether or not the delete key is operated in the flow of FIG. 8 (step C24). If the delete key is operated, it is determined whether or not there is lyrics data at the current address (step C25). If there is no lyric data, the process immediately returns to the main flow, but if there is lyric data, the lyric data at the current address is deleted (step C26). Thereafter, the type of the lyrics data at the next address is determined (step C27). If the determined lyric data is a character or a space, the empty area generated by the process of step C26 is filled (step C28). Then, the display is updated (step C29), and the process returns to the main flow.
[0040]
For example, in FIG. 11A, when the delete key is operated when the cursor position is at the letter “GA” of the lyrics, the lyrics data “GA” is deleted in the process of step C26. In this case, the lyric data at the next address is the character “B”, and the area of the character “GA” in the lyric data shown in FIG. Fill free space. As a result, the lyrics are changed to the lyrics shown in FIG.
[0041]
If the lyrics data determined in step C27 is a numerical value, the address of the lyrics data is incremented (step C30), and the lyrics data at the current address, that is, the numerical value is deleted (step C31). Then, it is determined whether or not there is lyrics data at the next address (step C32). If there is lyric data, the empty area generated by the process of step C31 is filled (step C33). After filling the empty area or when there is no lyrics data at the next address in step C32, the address of the lyrics data is decremented (step C34). Then, the display is updated (step C29), and the process returns to the main flow.
[0042]
When the lyric data determined in step C27 is a symbol, the address of the lyric data is incremented (step C35), and the value of the register AC is incremented (step C36). AC is a register for adjusting an address between automatic performance data and lyrics data. In the initialization, AC is reset to “0”. After AC is incremented, the lyric data at the current address is deleted (step C37). Thereafter, the address of the lyrics data is further incremented (step C38), the value of AC is incremented (step C39), and the lyrics data at the current address is deleted (step C40).
[0043]
Next, it is determined whether or not the lyrics data at the next address is a symbol (step C41). If it is a symbol, the process proceeds to step C35, and the above processes up to step C41 are executed. If the lyrics data at the next address is not a symbol at step C41, it is determined whether or not there is lyrics data at the next address (step C42). If there is lyric data, the empty area generated by erasing the lyric data in steps C37 and C40 is filled (step C42). After filling the empty area or when there is no lyrics data at the next address in step C42, the value of AC is subtracted from the address of the lyrics data (step C44), and AC is reset to “0” (step C45). ). Thereafter, the display is updated (step C29), and the process returns to the main flow.
[0044]
For example, in FIG. 11D, when the lyric data at the current address is “B” and the address is k, when the lyric data is deleted in the process of step C26, the determination is made in step C27. The lyrics data at the address k + 1 is the symbol “+”. Accordingly, the address k of the lyrics data is incremented to k + 1 in step C35, and the AC value is incremented from “0” to “1” in step C36. In step C37, the symbol “+” of the lyrics data at the current address k + 1 is deleted. Further, the address k + 1 of the lyrics data is incremented to k + 2 in step C38, and the AC value is incremented from “1” to “2” in step C39. In step C40, “ku” is deleted from the lyrics data at the current address k + 2.
[0045]
Next, in step C41, it is determined that the lyric data at the next address k + 3 is not a symbol (the character “is”), and in step C42, it is determined that there is lyric data at the next address k + 3. Therefore, the empty areas k, k + 1, k + 2 generated by erasure in step C43 are filled. Then, the AC value “2” is subtracted from the current address k + 2 of the lyrics data to obtain the current address k. As a result, in the lyrics data in FIG. 11D, “O” is set in the area of the current address k.
[0046]
If the delete key is not operated in step C24, it is determined whether or not the input key is operated in the flow of FIG. 8 (step C46). If the input key is not operated, the process returns to the main flow, but if the input key is operated, it is determined whether or not the lyric data has been assigned to all the notes (step C47). If the lyric data has not been assigned to all the notes, it is determined whether or not the current automatic performance data address is the head address (step C48). If it is not the head address, it is determined whether or not there is lyrics data at the previous address (step C49). If there is no lyrics data at the immediately preceding address, the process immediately returns to the main flow, but if there is lyrics data, the input key is classified (step C50).
[0047]
If the input key is a character, it is determined whether or not there is lyrics data at the current address (step C51). If there is lyrics data, the lyrics data after the current address are moved backward one by one, The current address is made an empty area (step C52). When there is no lyric data at the current address and it is an empty area, or when the data is moved backward to make an empty area, the characters of the lyrics data corresponding to the input key are written in the empty area (step C53).
[0048]
Next, the type of the lyrics data at the immediately preceding address is determined (step C54). When the lyrics data at the immediately preceding address is a character, a numerical value, or a space, the address of the lyrics data is incremented by 1 (step C55), and the address of the automatic performance data is incremented by 4 (step C56). Then, the display is updated (step C57), and the process returns to the main flow. In step C54, when the lyrics data at the previous address is the symbol “+”, the address of the lyrics data is incremented by 1 (step C58), and the display is updated without incrementing the address of the automatic performance data. (Step C57), the process returns to the main flow.
[0049]
For example, in FIG. 12, the letters “a” and “u” of the lyrics data are displayed corresponding to two notes of the automatic performance data, respectively, and the cursor is displayed at a position indicating the current address of the automatic performance data and the lyrics data. When the character “o” is keyed in the state of being in the state, the lyric data after the address “u” is moved backward in step C52, the address “u” is made an empty area, and the empty area is made in step C53. Write the lyric data "O" corresponding to the input key. In step C55 and step C56, the current address of the lyrics data and the current address of the automatic performance data are incremented. In step C57, the display is updated so that the characters “a”, “o”, and “u” in the lyrics data are displayed corresponding to the three musical notes of the automatic performance data, and the cursor position moves to the next musical note.
[0050]
In step C50, when the input key is a numerical value, the number of notes to which no character is assigned is counted (step C59), and a value obtained by adding “1” to the count value is smaller than the input numerical value. Is discriminated (step C60). The reason for adding “1” is that the first character for extending the voice is already input corresponding to one note before the numerical value is input, and that note is included in the input numerical value. When the count value + “1” is smaller than the input numerical value, the number of notes is insufficient with respect to the input numerical value, so the key input becomes invalid and the process returns to the main flow. If the count value + “1” is equal to or greater than the input numerical value, the type of the lyrics data at the immediately preceding address is determined (step C61). If the lyric data at the immediately preceding address is a space or a numerical value, the input of the numerical value is invalid and the process returns to the main flow. If the lyric data at the immediately preceding address is a character, the type of the lyric data at the previous address is further determined (step C62). If the lyric data at the address two before is the symbol “+”, the lyric data at the previous address is combined with the lyric data at the character three addresses before, so the key input becomes invalid and the main flow. Return to.
[0051]
In step C62, if the lyrics data at the previous address is a space, a numerical value, or a character, the input numerical value is valid. In this case, it is determined whether or not there is lyric data at the current address of the lyric data (step C63). If there is lyric data, the lyric data after the current address is moved back one by one to obtain the current address. Is made an empty area (step C64). When there is no lyric data at the current address and it is an empty area, or when the data is moved backward to make an empty area, the lyric data corresponding to the input key is written in the empty area (step C65). Then, the address of the lyrics data is incremented by 1 (step C66). Next, the type of the input key is determined (step C67). If the input key is a numerical value, a value obtained by subtracting “1” from the numerical value and multiplying by “4” is added to the address of the automatic performance data (step C68). Then, the display is updated (step C69), and the process returns to the main flow.
[0052]
For example, in FIG. 13, lyric data “sa” is input to the previous address, and the characters “ta”, “no”, and “sa” in the lyric data are displayed corresponding to the three musical notes of the automatic performance data, respectively. In the state where the cursor is displayed at the position of the note next to the note corresponding to “”, when the numerical value “4” is key-input, the number of notes “3” with no character assignment counted in step C59 is set. The number “4” obtained by adding “1” is determined to be the same as the input numerical value “4”. In step C61, the lyrics data “sa” at the immediately preceding address is determined to be a character, and the lyrics data “no” at the previous address is also determined to be a character. Next, at step C63, it is determined that there is no lyrics data at the current address. Then, as shown in FIG. 13, the numerical value “4” of the lyric data is written in step C65, and the display is updated in step C69 through steps C66 to C68. As a result of this display update, as shown in FIG. 13, one character “sa” and three symbols “−” that extend the voice are automatically displayed for four notes. In this case, since the fourth note is the last note of the song, the cursor position is displayed at a position without a note.
[0053]
In step C50, when the type of the input key is a space, the type of the lyrics data at the immediately preceding address is determined (step C70). If the lyric data at the previous address is a character, a numerical value, or a space, it is determined whether or not there is lyric data at the current address of the lyric data (step C63). Are moved back one by one to make the current address a free area (step C64). If there is no lyric data at the current address and it is an empty area, or if the data is moved backward to make an empty area, the lyric data of the space (pronunciation prohibited) corresponding to the input key is written in the empty area (step C65). . Then, the address of the lyrics data is incremented by 1 (step C66). Next, the type of the input key is determined (step C67). If the input key is a space, “4” is added to the address of the automatic performance data (step C71). Then, the display is updated (step C69), and the process returns to the main flow.
[0054]
If the lyric data at the previous address is the symbol “+” at step C70, the type of the lyric data at the previous three addresses is determined (step C72). If the lyrics data is not a symbol but a character, a numerical value, or a space, it is determined whether or not there is lyrics data at the current address (step C73). If there is lyric data, the lyric data after the current address is moved back one by one to make the current address a free area (step C74). When there is no lyric data at the current address and it is an empty area, or when the data is moved backward to make an empty area, the characters of the lyrics data corresponding to the input key are written in the empty area (step C75). Next, the address of the lyrics data is incremented by 1 (step C76). Then, the display is updated (step C77). In this case, since the staccato-like pronunciation is performed, the display form of the characters of the lyrics is changed from the others. After the display update in step C77, the process returns to the main flow.
[0055]
For example, in FIG. 14, the letters “I” and “ki” in the lyric data are displayed corresponding to two notes of the automatic performance data, respectively, and the cursor is displayed at a position indicating the current address of the automatic performance data and the lyric data. In the state where the symbol “+” is keyed and a space is keyed, in step C72, the character “I” which is the lyrics data of the previous address is discriminated, and steps C73 to C76 are performed. After that, the display is changed in step C77. In this case, since the pronunciation is staccato, “·” indicating staccato is displayed on the corresponding second note, and the display form of the letter “ki” of the lyrics is changed.
[0056]
Further, when the character “mi” is keyed in and then the symbol “+” is keyed in and then a space is keyed in, “space” which is the lyric data of the address three times before is entered in step C72. After the determination, the display is changed in step C77 through steps C73 to C76. In this case as well, since the pronunciation is staccato, “·” indicating staccato is displayed on the corresponding third note, and the display form of the letter “mi” of the lyrics is changed.
[0057]
In step C72 of FIG. 8, when the lyrics data at the third previous address is the symbol “+”, the character at the second previous address is displayed by the symbol “+” (the second previous lyric data is not a character). However, since this will be combined with the character at the previous address (this is also not a character), the key input space determined at step C50 becomes invalid. Therefore, in step C72, when the lyric data at the third previous address is the symbol “+”, the process proceeds to step C78 to determine the operation of a new input key.
[0058]
When all the notes have been assigned lyric data, this is valid only when the symbol “+” is added to any note and the character entered after that is combined with the character entered before the symbol “+”. Therefore, it is not possible to input lyrics data other than the symbol “+”. Therefore, when the lyric data has been assigned to all the notes in step C47, it is determined whether or not the input key is the symbol “+” (step C79). Return to. If the input key is a symbol, it is determined whether or not the address of the current automatic performance data is the head address (step C80). If it is the head address, the input of the symbol is invalid, and the process immediately returns to the main flow.
[0059]
If the input key is “+” in step C50, or if the address of the current automatic performance data is not the start address in step C80, the type of the lyric data at the previous address is determined in the flow of FIG. (Step C81). If the lyric data at the immediately preceding address is a space or a numerical value, the lyric data cannot be combined with the symbol “+”, so the key input is invalidated and the process immediately returns to the main flow. In addition, when the lyric data at the immediately preceding address is a symbol, two key inputs for the symbol are continuous. In this case as well, the key input is invalidated and the process immediately returns to the main flow.
[0060]
In step C81, if the lyrics data at the previous address is a character, it is determined whether or not there is lyrics data at the current address (step C82). If there is lyric data, the lyric data after the current address is moved back one by one to make the current address a free area (step C83). If there is no lyric data at the current address and it is an empty area, or if the data is moved backward to make an empty area, the characters of the lyrics data corresponding to the input key are written in the empty area (step C84). Then, the address of the lyrics data is incremented by 1 (step C85). Next, the process proceeds to step C78 in the flow of FIG. 8 to determine whether or not the input key has been operated.
[0061]
15 and 16 show the flow of the automatic performance process at step A12 in the flow of FIG. In this process, automatic performance data is read (step D1), and the read data is determined (step D2). If the read data is timing data, it is determined whether or not the timer value incremented by the timer interrupt in FIG. 5 has reached the read timing data (step D3). When the timing data is reached, the next event data of the timing data is executed, so the address of the automatic performance data is incremented (step D4), and the process proceeds to step D1 to read the next automatic performance data.
[0062]
In step D2, if the read data is a key-on event, it is determined whether the event data is the first key-on event (step D5). If it is not the first key-on event, the cursor position is advanced to the next key-on event (step D6), but if it is the first key-on event, the automatic performance processing for that event has not yet been performed, so the cursor The position is not stepped.
[0063]
Next, it is determined whether or not the register CT of the memory is “0” (step D7). CT is a register for storing any one of the numerical values “2” to “9” in the lyrics data, and is reset to “0” in the initialization process of the main flow. In step D7, when CT is “0”, it is determined whether or not there is lyrics data (step D8). If there is lyrics data, the lyrics data is read (step D9), and it is determined whether the read data is a character or a space (step D10).
[0064]
If the read data is a character, the address of the lyrics data is incremented (step D11). Then, the type of the lyrics data at the incremented address is determined (step D12). If the lyric data is a character or a space, the voice waveform data corresponding to the character read at the previous address is selected and read at the pitch reading speed of the key-on event (step D13). Next, the automatic performance data address is incremented (step D14), and the process returns to the main flow.
[0065]
If CT is not “0” in step D7, it is a case where one character is assigned to a plurality of notes and the speech is extended, so the speech waveform data corresponding to the vowel part of the character read at the previous address is selected. Thus, reading is performed at the reading speed of the pitch of the key-on event (step D15). Next, the value of CT is decremented (step D16). Then, the address of the automatic performance data is incremented (step D17). Next, it is determined whether or not CT has become “0” in the process of step C16 (step D18). When CT is not “0”, the process returns to the main flow, but when CT becomes “0”, the address of the lyrics data is incremented and the process proceeds to step D8 to determine whether or not the lyrics data is present.
[0066]
In step D10, if the read data is a space, since the note is silent, both the address of the automatic performance data and the address of the lyrics data are incremented (step D20). Then, the process returns to the main flow. That is, when a space that is a specific symbol is assigned to any one note, the sound of that one note is prohibited. That is, when a specific symbol (space) is input and assigned to one note, the sound generation of that one note is prohibited.
[0067]
In step D2, if the read data is a key-off event, the sound of the character corresponding to the currently sounding note is muted (step D21). Next, the automatic performance data address is incremented (step D22), and the process returns to the main flow.
[0068]
If the read data is END data in step D2, or if there is no lyric data in step D8, the mode flag is set to “0 (lyric input processing mode)” (step D23), and the automatic performance data Both the address and the address of the lyrics data are reset, and the cursor is moved to the head position (step D24). Then, the process returns to the main flow.
[0069]
If the lyric data is a numerical value or a symbol in step D12, the type of the numerical value or the symbol “+” is determined (step D25). If it is a numerical value, the numerical value is set in the register CT in the flow of FIG. 16 (step D26), the voice waveform data corresponding to the character read at the previous address is selected, and the pitch of the key-on event is read. Read at a speed (step D27). Then, the CT value is decremented (step D28), and the address of the automatic performance data is incremented (step D29). Then, the process returns to the main flow. That is, when one arbitrary character and numerical value are input for one note, one character input corresponding to a plurality of notes indicated by a numerical value including the one note is assigned in correspondence with the first character. The sound of one character is pronounced based on the pitch and length of a plurality of notes.
[0070]
If the lyrics data is a symbol in step D25 of FIG. 15, the address of the lyrics data is incremented in the flow of FIG. 16 (step D30). Then, the lyrics data is read (step D31), and it is determined whether the read data is a character or a space (step D32). If it is a character, the address of the lyrics data is incremented (step D33). Then, it is determined whether the lyric data at the address is a character or a symbol “+” (step D34). If the symbol is “+”, the address of the lyrics data is incremented (step D35), the lyrics data of the address is read (step D36), the process proceeds to step D33, and the address of the lyrics data is incremented. If the lyric data is the symbol “+” in step D34, the loop processing of steps D35, D36, D33, D34 is repeated. In this case, the lyrics data of a plurality of characters connected by the symbol “+” are read out for one note.
[0071]
In step D34, if the lyric data is a character, the speech waveform data corresponding to the characters continuously read up to the previous address is selected and sequentially read at the reading speed of the pitch of the key-on event (step D37). . Next, the address of the automatic performance data is incremented (step D38). Then, the process returns to the main flow. That is, when a specific symbol is input for one note, the characters input before and after the specific symbol are combined to assign a plurality of characters corresponding to the single note, and the assignment The voices of the plurality of characters are generated based on the pitch and length of the corresponding one note.
[0072]
If the read data is a space at step D32, the address of the automatic performance data is incremented (step D39), and the key-off timing data is read (step D40). Next, a value obtained by subtracting the previous key-on timing data from the key-off timing data is divided by “2”, and an operation of subtracting the divided value from the key-off timing data is performed, and the calculation result is used as key-off timing data. (Step D41). In this case, the sound generation time is shortened to half of the sound length of the automatic performance data.
[0073]
Next, the voice waveform data corresponding to the character read at the previous address is selected and read at the reading speed of the pitch of the key-on event (step D42). Next, the address of the automatic performance data is incremented (step D43). Then, the process proceeds to step D3 in FIG. 15 to determine whether or not the timer value has reached key-off timing data in which the sound length is shortened. That is, when a specific symbol is input after the input of any one character from the keyboard 3, if another specific symbol is input immediately after the specific symbol, the arbitrary one character The specific symbol and the other specific symbol are assigned to one note, and the note is generated in a time shorter than the note length of the one note.
