First, the present program recorded on the CD-ROM is read out, and when it is operated on a personal computer, it is determined whether or not a data editing mode for music editing is performed (step S101). If it is not the mode (step S101; No), step S shown in FIG.
The process proceeds to step 109 for determining whether or not the music learning support mode is set. On the other hand, if it is determined that the mode is the data editing mode (step S101; Yes), it is determined whether or not there is an instruction to read the edited musical score data (step S101).
102). When there is a read instruction (step S1
02; Yes), the edited musical score data is read (step S103). Thereafter, it is determined whether or not the editing has been completed (step S104). If the editing has not been completed (step S104; No), the process returns to step S104, and the above processing is repeated. When the editing is completed (step S104; Yes), the edited musical score data is stored (step S105). Then, a conversion request flag is set (step S106). On the other hand,

If the instruction is given (step S118; Yes), a performance process based on the MIDI data is performed (step S119). On the other hand, when it is determined in step S118 that there is no performance instruction (step S118; No), the process returns to step S101. Also, after the processing of steps S114 and S115 and step S119, the process similarly returns to step S101.

Next, the processing of the performance data conversion step in steps S111 and S117 of FIG. 4 will be described in detail.

(I) Performance Data Conversion Step (Steps S111 and S117) The musical score data readout processing performed before these steps S111 and S117 (step S110)
Since the data in step S116) is data suitable for displaying a musical score on a screen or printing it out, it is impossible to perform the performance process and the process of generating a floor name tone as it is. Therefore, the data is once converted into performance data.

This step is set to be scheduled and executed by the operating system periodically and intermittently (every 5 msec, for example), and the unit of execution is one bar of processing.

The total number of parts is PRnum and the total number of pages is P
num, the total number of paragraphs is Snum, the number of measures in the paragraph is Mnum
When all the bars belonging to one part are converted, then all the bars belonging to two parts are converted, and so on, until all the bars are completed.

At the time of execution, if the conversion request flag is set, it is determined that conversion is required by an editing operation, and the following processing is performed.

As the performance data, symbol data representing the type of music symbol and position coordinate data on the music score are sequentially extracted from the beginning of the displayed music score. A description will be given assuming that the music symbol in the Mth bar in the S paragraph of the PR page and the P page is a conversion target.

First, in the PR part, M in the S paragraph on page P
The address (pointer) of the symbol storage area of the measure is obtained. Then, the X coordinate of this bar is divided by Nm, and a symbol (strictly, the X coordinate of the center of the symbol defined in advance of the symbol: for example, the center of the ball of the note in the case of a note) exists in the division width. Check in order. This bar width is obtained from the X coordinate of the bar line of the bar on the display and the X coordinate of the next bar line. As described above, the bar X
The reason why the coordinates are divided by Nm is that a plurality of symbols within the division width act simultaneously at that time.

If there is a note, a rest, or a symbol related to strength, the type of the symbol is recognized, and the duration of the sound is obtained. In the case of a rest, the duration is obtained.

The above is an outline of the processing in the performance data conversion step.
12 is stored in a performance information storage area. The unit structure of the storage area has a structure including at least the following fields for each sound.

1) Event identification (indicating at least the distinction between a bar number event and a sounding event) 2) Note number 3) ON time (in the case of an event such as a note, the relative time from the beginning of the bar, an event meaning a bar) 4) Gate time 5) Music symbol type (ID) 6) Page number 7) Paragraph number 8) Measure number 9) Position within measure (X, Y) 10) Waveform calculation Number

The performance information storage area includes a sound generation start time counter for accumulating the sound generation start time.

The above is the outline of the processing of the performance data conversion step and the description of the configuration necessary for the processing. The details of the processing based on these steps will be described below.

First, a flag indicating a measure is stored in the event identification of 1). At this time, the start time of this bar (the value of the sounding start time value counter) is stored in the ON time field of 3), and the other fields are set to 0.

When a note is found, the pitch is obtained from the Y coordinate on the display of the note, converted to a note number according to the rules of music notation, and the sounding start is set in the ON time field of 3). Write the value of the time value counter. In addition, the duration of the note is obtained according to the type of the note, and input into the gate time field of 4). In order to highlight and display on the screen during the performance process, 6) page number, 7)
The corresponding data from the musical score data are also obtained and stored in the respective fields of the paragraph number of (8), the bar number of (8), and the position (X, Y) in the bar of (9).

Further, in order to confirm whether or not a chord is present, it is confirmed whether or not a plurality of notes are present at the same position, and the duration is similarly stored in the gate time of 4).

If all the notes in the section (for one bar) are converted as a unit of the performance information storage area, the gate time of all the notes in the section is used as the sounding start time value counter. (Cumulative addition).

If a rest is found, its duration is simply obtained and added to the sounding start time value counter.

By repeating the above procedure Nm times, performance data is obtained from the symbols represented in this bar. When the conversion is completed in units of one bar, this process is once ended.

Accordingly, by repeating this conversion process sequentially, performance data is generated as continuous data of the unit structure from the symbols described on the musical score. When the conversion of all measures is completed, the flag for generation of the floor name is set. This is because it is necessary to pass the whole converted part to the next step for generating a syllabary.

Next, the processing of the floor name sound data generation step of step S112 in FIG. 4 will be described in detail.

(II) Generation of floor name sound data (step S112) Here, data for sound generation is created from the performance data. The name of the floor is a melody used in general singing, such as "do", "le", "mi", "fa", "so",
It means the pronunciation when singing by the pronunciation of "la", "shi" and "do".

In this step, digitally represented audio data is generated from the performance data unit group.

In this processing, a performance information storage area, a floor name sound data storage area, and a synthesized audio waveform data storage area configured on the RAM 112 are used.

FIG. 5 shows an example of the storage state of performance data in the performance information storage area. In FIG. 5, reference numeral 10 denotes one of the units stored therein. Therefore, the performance information storage area stores the data generated by the performance data conversion means 4 as a continuous collection of such units 10.

FIG. 6 shows an example of a method of converting data including symbol data and position coordinate data by the performance data conversion means 4 into performance data. The data stored in the musical score data storage means 1 includes the symbol data and the position coordinate data of the musical score as shown in FIG. It indicates the speed at which a quarter note sounds 60 times per minute, that is, the length of the quarter note is 60000/60 = 1000 msec).

Performance data generated from the data representing these musical scores is stored in the performance information storage area in the state shown in FIGS. That is, the first first unit indicates the beginning of a bar, 1) the value of the event identification is 0, 2) the note number is-, 3) the value of the ON time is 0, 4)
The gate time is-, (others 5) to 10) are omitted).
The second unit indicates the first note of the first bar,
1) The value of the event identification is 1 (indicating that it produces sound), 2) The note number is 60 corresponding to the pitch, and 3) The value of the ON time is 0 (from the beginning of the bar). 4) Gate time is 96 (GT = 100 in this case)
0/96) and (others 5) to 10) are omitted). The vertical line representing the second measure is stored in the sixth unit, 1) the value of the event identification is 0, 2) the note number is-, 3) the value of the ON time is 384 (at the time of an event meaning a measure) The ON time indicates the relative time from the beginning of the music), 4) the gate time is-, and (others 5) to 10) are omitted). The seventh unit, which indicates the first note of the second bar, has 1) the value of event identification 1, 2) the note number 64, 3) the value of ON time 0, 4)
Gate time 96, (others 5) to 10) are stored).

FIG. 7 shows the performance data of a plurality of units between the first measure and the second measure stored in the performance information storage area as described above (here also 5) to 10). Omitted).

The scale name data stored in the scale name data storage area is a digitally expressed audio waveform corresponding to all scales included in the range to be pronounced in advance. It has the following structure.

11) Waveform data of sample name tone (sample value) 12) Start address and end address of waveform data of a part to be a consonant (eg, "D" for "do") 13) Floor The start address and end address of the waveform data of the part that becomes the vowel of the famous sound (for example, "O" for "do")

[0070] These are stored in correspondence with each scale, which is the scale name sound data stored in the scale name sound data storage area. If the length of the vowel part is set to be sufficiently longer than the intended sounding length, it is not necessary to repeatedly read the vowel part.

FIG. 8 shows sample values of the waveform data of the floor name tone of the above 11), in which a header portion is first, followed by a consonant portion and a vowel portion. In this example, the sampling rate is 22 KHz, and all types of floor names are stored in this format.

The synthesized audio waveform data stored in the synthesized audio waveform data storage area is digitally expressed audio waveform data generated based on the performance data and floor name data. The storage area for this data has a single buffer structure, to which writing by the floor name sound data generating means 5 and reading by the musical sound generating means 6 are performed.

As shown in FIG. 9, the main floor name generation step is also set to be scheduled and executed periodically and intermittently (for example, every 10 msec) by the operating system. In this single execution, Sn (for example, 256) sample values are calculated here. If the sampling rate is 22 KHz here, it means that a waveform for (256/22) msec time is calculated. Here, all Sn (for example, 256) sample values generated in this processing unit are:
The time that is actually reproduced as the floor name is called DT.

The above is the outline of the processing of the floor name sound data generation step and the description of the configuration necessary for the processing. The details of the processing based on these are described below.

From the first unit in the performance information storage area on the RAM 112, the name of the floor name to be pronounced (note number) is obtained, and the data of the "consonant part" and the data of the "vowel part" are stored in the floor name sound data storage area. , And processed in accordance with the ON time of 3) and the gate time of 4), and stored in the synthesized audio waveform data storage area. The above processing is performed in the following procedure. The gate time in 4) is a relative time (for example, the length of a quarter note is 9
6), it is changed to a normal time expression based on the performance tempo, and the time of one gate time (1 ON time) is set to GT.

Setting the execution number counter The method includes the step of incrementing the execution number counter by one every time the operating system is called. This counter is cleared in the case of processing from the beginning.

The comparison with the sound generation start time in the performance information storage area (sound generation start processing) (counter value of the execution number counter × DT) indicates the elapsed time from the head unit to the unit to be sounded. Further, (ON time of each unit in the performance information storage area × GT) indicates the sound generation start time of the floor name specified by the unit. Therefore, by comparing (counter value of execution number counter × DT) with (ON time × GT), the unit of the performance information storage area to be calculated in the processing unit is specified. That is, if there are ON-time units that satisfy (execution number counter value × DT) = (ON time × GT) or (execution number counter value × DT)> (ON time × GT), those units correspond to those units. Generate an audio waveform. In addition, the above ON
The time is for the first measure. From the second measure on, the ON time of the measure to which this unit belongs is added, and "ON"
Time = ON time + ON time of a unit indicating a bar is used in the comparison processing.

For example, if the value of the execution number counter is N, units to be sounded by N × DT time are to be generated, and Sn units corresponding to the time indicated by the execution number counter value (N) (for example, Sn) 256 sample values are calculated. The calculation of the sample value in this section is performed as follows. A floor name sound data storage area corresponding to the note number of the target unit (for example,
Are read from the floor name sound storage area in which is stored, and the Sn sample values are stored in the synthesized audio waveform data storage area. When a chord is composed (for example, when "do" and "mi" are pronounced simultaneously), there are a plurality of units corresponding to them, so that they have the same number of Sn sample values. Are read out and added, and the Sn sample values are stored in the synthesized audio waveform data storage area (for example, if “do” and “mi” sound simultaneously, the floor name of “do” Sn from the sound data storage area, "Mi"
Sn sample values are read from the floor name sound data storage area, and the sum of the sample values of “do” and the sample value of “mi” is added to generate Sn total sample values, Stored in the synthesized audio waveform data storage area).

When the operation of each target unit is completed, the field of the number of waveform operations of each unit is incremented by one. This waveform calculation field is incremented by one each time Sn sample values are generated, and is used to know the progress from the start of sound generation. Here, only the unit for which sound generation has started is targeted. That is, the field of the number of times of waveform calculation is zero. As shown below,
Later, the field of the number of waveform operations becomes 1.

Repetition processing of loop part Next, the sound generation has already started in the section of the execution number counter N (that is, the field of the number of waveform operations is 1
(Units not subjected to the processing described above) are searched, Sn sample values are obtained, and these and the Sn sample values obtained above are read from the audio waveform data storage area, added, and added. The resulting S
Write n sample values to the audio waveform data storage area.

This process is a process for obtaining a sample value after the start of sound generation, and similarly stores a floor name sound data storage area (for example, “F”) corresponding to the note number of the target unit. A result obtained by reading Sn sample values from the (story name sound data storage area) (at this time, the read name of the scale name sound data storage area is obtained by (field of the number of waveform operations) × (sample point number Sn of this section)) Is added.

Post-processing The field of the number of times of waveform calculation of the target unit is incremented by one.

Sound generation stop processing (gate time × GT) is set to (waveform calculation number field ×
DT) The sound generation stop processing is performed on the smaller or equalized unit. This processing is performed by setting -1 in the field of the number of waveform operations of the unit. Those for which -1 is set are excluded from the processing target, and as a result, the sound generation is stopped.

Further, when the sound is stopped, the mute processing can be performed with smooth attenuation. That is, (gate time x
The waveform amplitude may be multiplied by an attenuation value as (GT)-(waveform operation count field × DT) becomes a negative value, and when a predetermined negative value is reached, the waveform amplitude may be removed from the processing target.

To summarize the above processing, the unit in the performance information storage area is searched, and the processing is classified according to the field value of the number of times of waveform operation. In other words, those for which the field value of the number of waveform operations is 0 have not yet been subjected to sound generation processing, those for which 1 or more have sound generation started and continued, and those for which -1 has been subjected to sound generation stop processing. It is.

As described above, the audio waveform data storage area sequentially stores the audio waveforms to be generated at predetermined intervals by repeatedly performing the processings of the steps (1) to (4). By passing the audio waveform to a predetermined operating system, a tone can be generated. Depending on the operating system, the method of playing the audio waveform is easily realized according to the function of each operating system.

FIG. 10 is a time chart showing how the floor name sound is generated when the above steps are executed. The first (a) to (c) are the times at which the floor name should be pronounced calculated based on the data obtained from the performance information storage area (the “do” in the first bar in FIG. Corresponding to FIG. 10 (a), the same applies to (b) and (c) below). Here, since the tempo was 60, GT = 1000/96. As shown in FIG. 10B, the ON time is 96
× GTmsec, and the gate time is also data for 96 × GTmsec. Data corresponding to a predetermined tone generation time is read out from the floor name sound data storage area in correspondence with the ON time and the gate time, and written into the synthesized audio waveform data storage area as shown in FIG.

In the above example, a method of generating audio waveforms to be generated at once has been described. However, after an instruction to start a performance, at least two audio waveform data storage areas (buffers) having a length of a predetermined period are stored. By switching between prepared and used for reproduction and storing the waveform generation result at predetermined intervals (interlib), it is also possible to reproduce without storing all the waveform data to be reproduced.

As described above, since the audio waveform is calculated intermittently by periodically dividing it into certain sections and generating the audio waveform in parallel with the processing for the musical note display data creating step, the editing is performed. Waveform generation can be performed by effectively using the idle time of an operation or another operation, and performance can be started immediately.

Further, as for the progress of the music accompanying the reproduction, the predetermined position of the note or rest to be converted is extracted from the musical score data storage means 1 and stored in the performance information storage area for storing the performance data. In advance, while counting the elapsed time from the reproduction, the display color of the note is highlighted with a color distinguished from the others in synchronization with the sounding of the corresponding note. For example, it may be "red" during pronunciation, and may return to the original color at the end of pronunciation. This can be performed by simply executing a process of changing the color and overwriting on the screen.

Further, since the floor name is inevitably determined by the key and the note position on the music, when the note is pasted at the time of editing,
It is also possible to display using outline fonts with note names with floor names.

In this way, by generating a floor name tone in accordance with the displayed musical score, it is possible to realize an educational system that is extremely effective for music education, especially for reading music.
