Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic musical performance device, and particularly to an improvement of a timing information processing section.

[Summary of the Invention] This invention stores the pronunciation timing for each note using sequential intra-section timings determined within a unit performance section shorter than one measure, and also stores the length of a pause period that is longer than the unit performance section. By storing the number of unit performance sections, it is possible to play songs with long pauses with a small storage capacity.

[Prior Art] Conventionally, automatic performance devices capable of playing melodies, etc.
A system is known in which the sound generation timing of each note is expressed as a relative time from the previous key-on or key-off event and stored.

Further, as another pronunciation timing expression format, one in which the pronunciation timing is expressed as an absolute time within l or a plurality of measures is known, for example, in the field of autorhythm.

[Problems to be Solved by the Invention] The relative time-based pronunciation timing expression format described above has the advantage of being able to use a relatively small number of timing data bits, but once the pronunciation timing of a note shifts during a performance, The influence extends to subsequent notes, and when the autorhythm is played in synchronization with the melody, there is an inconvenience that the melody and autorhythm are out of synchronization.

On the other hand, according to the above-mentioned sound generation timing expression format using absolute time, there is no problem as mentioned above, but if, for example, 32 timings are to be expressed in 2 measures, 5-bit data is required as timing data. Normally, data is handled in units of 1 byte (8 bits), so in such a case, 1 byte will be allocated only to timing data, and it will have to be a separate byte from pitch data, etc. Therefore, the amount of data to be stored increases, and a large capacity performance data memory is required.

In this case, in order to reduce the number of bits of timing data, it is possible to express the timing within a performance section shorter than the 1lJX section, but simply doing this will not allow the song to have a pause period longer than the performance section. Unable to play,
There is a problem in that the songs to be played are restricted.

An object of the present invention is to reduce the storage capacity of a performance information storage section and to enable the performance of songs with long pause periods when a sound generation timing expression format based on absolute time is adopted.

[Means for Solving the Problems] An automatic performance device according to the present invention includes a storage means, a means for generating a tempo clock signal, a measuring means, a reading means, a musical tone generating means, a detecting means, and a controlling means. It is equipped with

The storage means divides the l/JX section of the piece of music to be performed into a plurality of equal parts, determines a unit performance section corresponding to the length of one of the sections, and divides the section into a plurality of equal parts and performs a unit performance section corresponding to the successive section. The timing within the section is determined, and the note information and rest information in the direction are stored according to the melodic progression using these timings within the section. Timing information representing the timing within the section corresponding to the sounding timing of the note within the unit performance section to which it belongs and pitch information corresponding to the pitch of the note are stored, and the pause information is the length of the unit performance section. Regarding the pause period having the above length, timing information representing the first of the sequential intra-section timings and pause period information representing the length of the pause period in terms of the number of unit performance sections are stored.

The measuring means measures the sequential intra-section timings based on the tempo clock signal, and sequentially generates intra-section timing information representing the respective intra-section timings, and sequentially generates such intra-section timing information. This is repeated at a cycle corresponding to a unit performance section.

The reading means reads out the note information and the pause information from the storage means according to the musical progression based on the intra-section timing information from the measuring means, and reads certain timing information according to the intra-section timing information. When the timing information is output, it is determined whether these pieces of information match the timing within the section, and on the condition that the matching occurs, reading is carried out sequentially to enable reading of the next timing information according to the timing information within the next section. If the timing information relates to the note information, pitch information related to the timing information is sent out, and if the timing information relates to the pause information, the pause period information is sent out.

The musical tone generating means generates a musical tone signal corresponding to the pitch information sent from the reading means.

The detection means detects the end of the rest period indicated by the rest period information by counting the number of unit performance sections based on the tempo clock signal in response to the rest period information being sent from the reading means. and generates a detection output.

The control means controls to stop reading information from the storage means in response to the suspension period information being sent from the reading means, and controls restarting reading of information from the storage means in response to a detection output from the detection means. It is something to do.

[Function] According to the configuration of the present invention, since the pronunciation timing for each note is expressed using the sequential intra-section timing determined within a unit performance section shorter than one measure, the pronunciation timing per note is The number of bits of timing information can be reduced.0 For example, if the unit performance section is a half-year bar, and the timing within the section is determined in correspondence to the 16th note within this section, there will be 8 sections within a half bar. Since it is sufficient to express the inner timing, 3 bits is sufficient for the number of bits of pronunciation timing information per note.

If, for example, 1 byte of data is used as the pronunciation timing information per note, 3 bits are needed to represent the pronunciation timing, so if the remaining 5 bits are used for other purposes such as pitch expression, Performance information for a note can be expressed in one byte. Therefore, the number of bytes for performance information for one song is approximately half that of the conventional one, and the storage capacity of the performance information storage section can be significantly reduced.

In addition, for a pause period that is longer than a unit performance section, pause period information whose length is expressed by the number of unit performance sections is stored, and in response to sending out the pause period information at the timing within the first section. The reading of information from the storage means is controlled to stop, and when the number of unit performance sections is counted and the pause period indicated by the pause period information comes to an end, the reading of information from the storage device is controlled to restart. Even a piece of music having a pause period longer than the length of a unit performance section can be played without any problem.

Circuit Configuration of Alarm Clock (FIG. 5) FIG. 5 shows the circuit configuration of the alarm clock shown in L. In this clock, the various automatic operations described above are controlled by a microcomputer.

The data bus 30 includes a central processing unit (cPU) 32, a program memory 34, a register group 38, a performance information memory 38, a table memory 40, and a tempo clock oscillator 42.
, a switch group 44, a display group 46, a tone generator (TG) 48, and the like are connected.

The CPU 32 executes processing in various modes according to programs stored in the program memory 34.
These processes will be described later with reference to FIGS. 15 to 27.

The register group 36 includes flags, counters, registers, etc. used in various processing by the CPU 32, and the registers related to the implementation of the present invention will be described later.

The performance information memory 38 contains performance information (for 376 songs).

It stores tone parameter information, rhythm pattern information, bass pattern information, etc., and the details of the stored contents will be described later with reference to FIGS. 7 and 8.

The table memory 40 stores conversion tables regarding scale names, ranges, tempos, volume, etc. The details of the stored contents will be described later with reference to FIG.

The tempo clock oscillator 42 generates a tempo clock signal TCL having a frequency corresponding to the tempo data TD. The signal TCL is supplied to the CPU 32 as an interrupt signal and is used to control automatic performance sound generation.

The switch group 44 includes the aforementioned mode switch MO5, up/down switch UDS, demo/cursor switch DO3, and stop switch srs'.

The display group 46 includes various displays belonging to the display section 12 described above.

TG4B includes the sound source TGI for the 1st part, the sound source TG2 for the :52 part, and the sound source 1 for the bass;
a, and a rhythm sound source TGR.

Both sound sources TGI and TG2 have a two-channel configuration, and each sound source can simultaneously produce up to two tones. In addition, the sound source T G B has a one-channel configuration, and the sound source T
The GR includes percussion sound sources such as a bass drum, snare drum, tambourine, by-bat oven, by-bat close, and so on.

The clock oscillator 50 generates a clock signal C of 2 [Hz].
The signal CL is supplied to the CPU 32 as an interrupt signal and is used to obtain a clock function.

The sound system 52 includes an output amplifier, the aforementioned speaker 14, etc., and is configured to convert various musical tone signals from the TG 48 into sound.

In the configuration shown in FIG. 5 described above, key codes for each note name are determined in advance as shown in FIG. 6.

7 and 8) FIG. 7 shows the data format of the performance information memory 38, and the memory 38 includes a performance music storage section FAT.
A timbre parameter storage section TPM, a rhythm pattern storage section RPM, and a base pattern storage section BPM are provided. In either storage section, the data length per l address is 1 byte (8 bits).

In the performance music storage unit FAT, the surface length data of the first to 378th music pieces are sequentially stored as head data HD, and then the first music data and the 376th music data are sequentially stored.

The surface length data of 6 songs is 1 of the number of bytes of the corresponding song data.
/2 is expressed in 8 bits. For example, if the value of the surface length data of the first song is Ll, the actual number of bytes of the first song data is LIX2.

The reason why the value corresponding to half of the actual gray hair is stored as the face length data is to reduce the number of bits of the face length data. That is, although approximately 9 bits are required to represent actual gray hair, 8 bits are sufficient by storing a value equivalent to half the oil length. - As an example, an oil length equivalent to 510 bytes is stored as an oil length of 255 bytes using 8-bit surface length data.

Of the 376 songs prepared for performance, 388 are unique songs that are assigned in advance to each of the 368 days of the year, and the remaining 10 songs are special songs that can be assigned to desired dates such as birthdays, wedding anniversaries, etc. It's a song.

The music data for each image can have a two-part structure, as typically shown for the first music data. The data of the 1st part is the part data PHD+, and the data of the 1st part is
Byte number data representing the number of bytes of the part (cross 1),
The time signature/tempo data representing the time signature and tempo of the song, the tone data specifying the tone of the first part, and the range data specifying the range of the first part are arranged in sequence, and then the fB for the first part is placed. This is an arrangement of part-time performance data. In addition, for the data of the second part, timbre data specifying the tone of the second part and range data specifying the range of the second part are sequentially arranged as Rad data PHD2 for the part, and then the data for the second part This is an arrangement of the performance data of No. 1.

For time signature/tempo data, the highest pitch (MSB) is 1
If it is, it represents 4 beats, and if it is O, it is 3 beats, the lower 4 bits represent any tempo level TMP from 0 to 15, and the remaining 3 bits are unused.

Each timbre data specifies a timbre using a predetermined timbre number for each timbre, and its data format is the same as the second byte of the timbre data, which will be described later with reference to FIG. In this example, the number of specifiable tones is 12.

By using T's memory data, the melody,
Automatic performance of chords, etc. becomes possible. Note that a storage example of the storage unit FAT will be described later with reference to FIGS. 1+ and 12.

The timbre parameter storage unit TPM stores timbre parameter information for 128 timbres corresponding to timbre numbers 0 to 127, respectively. By referring to the storage unit TPM, the timbre data is converted into corresponding timbre parameter information.

The rhythm pattern memory RPM contains march, bossa nova,
Rhythm pattern data corresponding to 31 types of rhythms such as . These 32-byte sound source control data are stored in 32 addresses corresponding to the count values O to 31 of the tempo clock signal TCL, and examples of their storage will be described later with reference to FIGS. 13 and 14. do. In this embodiment, by matching rhythm type data specifying the rhythm type to the song data of a desired song, it is possible to perform an automatic rhythm performance suitable for the song.

The base pattern storage unit BPM stores base pattern data corresponding to each of the 31 types of rhythms described above, and the base pattern data corresponding to each rhythm type is a 32-byte base control representing a base pattern for two bars. It consists of data. These 32 bytes of base control data are stored in 32 addresses corresponding to the count values 0 to 31 of the tempo clock signal TCL, and each base control data is stored at each of the 32 addresses corresponding to the count values 0 to 31 of the tempo clock signal TCL. If all the bits are 0, and if the sound is required, the bass interval from the root note C is expressed by the number of semitones. In this embodiment, chord data specifying the root note and type of the chord is included in the song data of the desired song, and the bass pitch is determined based on this chord data and the bass pitch indicated by the bass control data. By doing so, it is possible to perform automatic bass performances that match several songs. In this case, the bass pattern data is selected according to the rhythm type data, and it is possible to perform a bass performance that matches the rhythm.

FIG. 8 shows the format of various performance data. Performance data consists of 1-byte data that controls the generation or disappearance of sounds, and 2 data related to other performance controls.

The 7th bit) CMSR) represents a sound command (=1), and the key-off data represents the mute timing and pitch for a note. It has the same structure as the data.

The grade number NNO is predetermined for each grade as shown in FIG. 9(A). In Figure 9 (A) 1, we have adopted scale names that span two octaves from G (-) to G (+), but this is because ordinary songs tend to have this range as a rule of thumb. This is due to the large number of

Timing TIM is the timing within the section, and is 0 to 7.
Takes one of the following values. Here, the timing within the section is
As shown in FIG. 11, it is determined by taking a half step as a unit performance section, dividing it into eight equal parts corresponding to 18th notes, and assigning numbers 0 to 7 to each successive section.

In the pause data, the 0th to 3rd bits of the first byte represent a control command with rl 111J, the 4th to 6th bits represent the start timing of a half step with timing TIM=roooJ, and the MSB is 0. In addition, in the second byte, the 0th to 3rd bits indicate the length of the pause period, the number of half steps S.
It is expressed as KP, and the 7th to 5th bits are rooIJ.

For example, if 5KP=2, a pause period equivalent to one measure will be obtained.

The accidental symbol data, chord data, and end data are all the same as the first byte of the pause data except that the first byte represents an arbitrary timing TIM, so their explanation will be omitted, and only the second byte will be explained. The second byte of the accidental symbol data is the Oth pip) (LSB) is O or 1.
represents a sharp or flat symbol number SF, respectively, and the 7th to 1st bits are rooooo 11J. The accidental data acts to raise or lower the pitch of the key-on data or key-off data placed immediately after it by a semitone. In the second byte of the chord data, the second to fifth bits represent a chord type number TYP of O to 3, the second to fifth bits represent a root note number ROOT of O to 11,
The 7th to 6th bits are "Ol", TYP = 0.1°2.3 corresponds to major, minor, seventh, and minor seventh, respectively, and ROOT = 0.1...11 corresponds to C, CI, respectively. ...corresponds to B. As ROOT,

Relationship between dates and song numbers (Figure 10) Figure 10 shows the relationship between annual dates, serial song numbers, and special song numbers.

The songs with serial song numbers 1 to 36B are unique songs that are assigned in advance to each of the 366 days from January 1st to December 31st, and the special song number for each of these unique songs is set to 0. . The unique songs are New Year's songs for January 1st, other songs for January 2nd, and so on, with different song numbers from 1 to 0.
36B corresponds to the dates of the year, and in order to facilitate the process of deriving the dates of the year, which will be described later, it is preferable to store the dates corresponding to the calendar days of the year in the table memory 40 or the like.

The songs with serial song numbers 367 to 37I3 are special songs that can be arbitrarily assigned to a desired date, and are given special song numbers 1 to 10, respectively. There are 10 special songs that are different from each other, such as songs for wedding anniversaries, songs for birthdays, etc.

FIG. 12 shows part of the data of the first and second parts stored in the storage unit FAT for the song shown in FIG. 11 shows the range data and the performance data of sections a and b in FIG. 11. In Figure 12,
[T I Ml is the timing TIM shown in FIG.
This corresponds to

In the data of the first part, the tone data as part data PHDI represents the tone number TONO=4 corresponding to the trumpet tone,
Range data as part head data PHDI is 0
Range number TR corresponding to the range from 2 to C4 (F major),
This represents N0=27. After this, the performance data for section a includes key-on data (TIM=O) representing the scale name of the first note "G", and key-on data (TIM=O) representing the scale name of the second note "N".
key-on data (TIM=1) representing the key-on data (TIM=1), key-off data (TIM=2) for erasing the note of the scale name "G", rhythm type data (TIM=2) representing the rhythm number RHY=2 corresponding to the march. , key-on data (TIM=O

In the data of the second part, Rad data PH to the part
The timbre data as D2 represents the timbre number TONO=9 corresponding to the piano timbre, and the range data as the part rad data PHD2 represents TRN0=27 as in the first part. After this, the performance data for the first section a is the rest data (TIM-〇) representing the rest period of 1 and a half year setsubun, and the key-on representing the scale name "C" of the lower of the first two notes of the second measure. data (TIM=O), key-on data (T1M=O) representing the scale name "Mi" of the higher note of the two notes, scale name "
Key-off data (TIM=1) to erase the “C” sound.
. . . are stored sequentially, and performance data corresponding to the content of the song is stored in the same way after the interval 0. In the performance data of the 0th interval, the accidental symbol data representing a sharp is key-on data with the scale name "n". and key-off data, and the accidental symbol data is used to set the pitch of the note "G" in the scale name a semitone higher.

Storage of Rhythm Patterns (FIGS. 13 and 14) FIG. 13(A) shows a rhythm pattern for two measures of bossa nova as an example of the rhythm pattern to be stored in the rhythm pattern storage unit RPM. indicates the performance content of the buy butt close, rsDJ indicates the snare drum, and rBDJ indicates the bass drum performance.TCLK=ON15
is the count value of the tempo clock counter described later in the case of four beats, and represents the sequential clock timing within the bar based on the tempo clock signal TCL.
BAR=0 or 1 is the value of the bar flag described later,
This measure flag is set to O and 1 alternately for each measure as the measure progresses.

Here, by combining TCLK and TBAR, 32 clock timings can be expressed within 2 bars. That is, according to the formula TBARX 1B+TCLKK, the clock timing of θ~31 is determined,
It is possible to specify control details such as whether or not the percussion sound source needs to produce sound at each clock timing.

FIG. 14 shows rhythm pattern data in which the rhythm pattern of FIG. 13(A) is expressed using 32-byte sound source control data corresponding to 32 clock timings using such an expression format.

The 32-byte sound source control data corresponding to the clock timings 0 to 31 is stored in the bossa nova storage area of the storage unit RPM in correspondence to the addresses 0 to 31. however,
In FIG. 14, since all bits of the sound source control data corresponding to each odd address are O, illustration of the addresses and data contents is omitted.

In the sound source control data corresponding to each even address,
The instruction contents of the Oth to seventh bits are predetermined as follows.

Bit number -K! L - ○ Necessity of pronunciation of By Butt Close HHC ■ Necessity of pronunciation of By But Open HHO 2 Necessity of pronunciation of Tambourine TM 3 Necessity of pronunciation of Snare Drum SD 4 Necessity of pronunciation of Bass Drum BD 5 Not used 6 Whether or not roll pronunciation is necessary 7 Whether or not accent is necessary Here, regarding the necessity or not, if it is necessary, it is l, and if it is not, it is O.

The above-mentioned 32-byte sound source control data is read repeatedly in the order of address progression based on the tempo clock signal TCL, and the rhythm sound source TGR is read out in accordance with each read data.
By controlling the , automatic rhythm performance of bossa nova can be performed.

By the way, Figure 13 (B) shows a rhythm pattern for two measures of a waltz, which uses the first to third beats of the bossa nova rhythm pattern of Figure 13 (A) for each measure. It is. In order to perform such an automatic rhythm performance of the waltz, the sound source control data for three beats from the first to third beats of each measure of the rhythm pattern data shown in Fig. 14 is read out to control the rhythm sound source TGR. In other words, for a waltz song, the rhythm type data specifies Bossa Nova, which can be used as a pattern, to read and specify the pattern data in Figure 14, and the time signature and tempo data specifies triple time. As a result, the value of TCLK is set to 0 to 11 within a measure, and in the first measure of the pattern data in FIG.
At each measure, sound source control data at addresses 16 to 27 are read out.

In this way, there is no need to store a rhythm pattern exclusively for the waltz, and the storage capacity can be reduced. Also,
The storage unit RPM stores 31 types of rhythm patterns as described above, but since one rhythm pattern is shared by multiple rhythm types as described above, the number of rhythm types that can actually be played is more than 31 types. Become. Note that the diversion of rhythm patterns is not limited to reusing a part of a four-beat pattern as a three-beat pattern, but also by repeating a two-beat pattern to make a four-beat pattern, or by reusing a four-beat pattern. It may also represent a six-beat pattern.

Next, the initial setting process, normal display process, time setting process, alarm time setting process, special setting process, and demonstration performance process in the main routine will be sequentially explained with reference to FIGS. 15 to 21.

Initial Set Process (FIG. 15) The initial set process shown in FIG. 15 starts when the power is turned on.

First, in step 60, 5TPF is set to 1 and PLAY is set to 0. Then, the process moves to step 62.

In step 82, set 88 to YEAR, 1 to MON,
Set 1 to DAY and O to WEEK. In other words, the date is January 1, 1988 (Sunday).
is set. Further, O is set to HOUR1MIN, SEC, and LED. After this, the process moves to step 64.

In step 64, ALMH is set to 12, and ALMM is set to O. That is, the alarm time is set to 12:00. After this, the process moves to step 6B.

In step 86, O is set in all of 5P(1) to S P (38B). That is, unique songs can be played on each of the 368 days of the year. Then, the process moves to step 68.

In step B8, TVOL is set to 4 (corresponding to the maximum volume). After this, the process moves to the normal display process shown in FIG.

Normal display processing (Fig. 16) In the normal display processing of Fig. 16, the processing of step 70 is necessary when moving from the processing of Fig. 20 or 21 described later to the processing of Fig. 16. In this step 70, all KCBUF (KCBUFI, KCBUF
2, etc.) and performs key-off processing to stop all sound sources belonging to the TG 48 from producing sound. Then, the process moves to step 72.

In step 72, MON, DAY, WEEK, HOU
The contents of R and MIN are respectively displayed at predetermined positions on the display section 12 as shown in FIG. 3(A). Then, in step 74, PLAY is set to 0, and then the process moves to step 76, where MDNO is set to O (corresponding to the normal display mode).

Next, in step 78, it is determined whether the switch MO3 is on, and if the result of this determination is affirmative (Y), the process moves to the time adjustment process shown in FIG. 17.

If the determination result in step 78 is negative (N), the process moves to step 80, and it is determined whether switch DO3 is on. If the result of this determination is affirmative (Y), the process moves to the demonstration performance process shown in FIG.

If the determination result in step 80 is negative (N), the process moves to step 82, where it is determined that the switch STS is in the on state.Normally, the switch STS is not turned on, so the determination result in step 82 is negative (N). ), and step 8
Move on to 4.

In step 84, 5TPF is set to 0.

For example, when step 84 is reached for the first time after step 80, the value of 5TPF changes from 1 to 0. Step 84
After that, the process returns to step 78 and the above-described process is repeated.

When the switch STS is turned on, the determination result in step 82 becomes affirmative (Y), and the process moves to step 8B. In step 8B, it is determined whether 5TPF is O.

For example, in an exceptional case where the switch STS is turned on when the power is turned on, the determination result in Step 5 8B is negative (N) and the process returns to Step 78. and,
The processing from step 78 onwards is repeated in the same manner as described above.

For example, if the switch STS is turned on during an alarm performance, the determination result in step 8B is positive (
Y), and the process moves to step 88. In step 88,
Set 1 to 5TPF. Then, the process moves to step 30.

In step 90, it is determined whether PLAY is 1 or not. As described above, when the switch STS is turned on during the alarm performance, PLAY=1, so the determination result in step 90 is affirmative (Y), and the process moves to step 92. Step 9
In step 2, PLAY is set to 0 (/), and the process moves to step 94.

In step 94, in the same way as step 70, all KCBs are
A key-off process is performed to clear the UF and stop the TG 48 from producing sound.

When the process in step 94 is completed or the determination result in step 80 is negative (N) (for example, the switch STS was turned on in a non-performance state), the process returns to step 78;
Repeat the process as above.

Time Adjustment Process (FIG. 17) In the time adjustment process shown in FIG. 17, in step 100, the display section 12 is caused to display as shown in FIG. 3(B). In other words, along with the root that displays "19" in the January position and the contents of TEAH in the day position, WEEK,
The contents of HOUR and MIN (7) are displayed at respective predetermined positions. Then, the process moves to step 102.

In step 102, MDNO is set to 1 (corresponding to time adjustment mode). Then, in step 104, CUR
After setting 1 to CHG and 0 to CHG, the process moves to step 10B.

In step 10B, the display corresponding to the value of CUR is blinked. For example, step 1
When the time comes to 06, the TEAH display flashes.

Next, in step 108, it is determined whether the switch MO3 is on. If this determination result is affirmative (Y), the process moves to the alarm time setting process shown in FIG. 18.

If the determination result on step 10 is negative (N), the process moves to step 110, and it is determined whether the switch UDS is on. If this judgment result is affirmative (Y), move to the stage/bu 112, YEAR, MON, DAY, WEEK,
The value of the register corresponding to the cursor position (blinking position) among HOUR and MIN is respectively increased or decreased within a limited range according to the up or down operation. The display contents at the cursor position are also changed in accordance with such changes in register values. After this, the process moves to step 114, where CHG is set to 1.
Set.

When the process of step +14 is completed or step 110
If the judgment result is negative (N), step 11
8, it is determined whether the switch DOS is on. If this determination result is affirmative (Y), the process moves to step 118.

In step 118, the value of CUR is increased by 1. In this case, the value of CUR shall be limited to a range of 1 to 6,
If it is 6, set it to l. After this, the process moves to step 120.

In step 120, if CUR=1, the year is displayed in the month/day position, as in step 100, and if CUR=1, the month/day (contents of MON and DAT) is displayed.

When the process of step 120 is completed or step 118
If the judgment result is negative (N), step 10
Return to step 6 and repeat the above process.

According to the processing of steps 106 to 120 described above, by appropriately operating the switches DO3 and UDS, the year number,
The month, date, day of the week, hour, and minute can be set arbitrarily.

Alarm time setting process (FIG. 18) In the alarm time setting process shown in FIG. 18, the step 130 determines whether CHG is 1 or not. If this determination result is affirmative (Y), it means that there has been a time change, and in step 132 SEC is set to 0. This is to start the seconds from 0 for the newly set time.

When the process of step 132 is completed or step 130
If the judgment result is negative (N), step 13

In step 13B, MDNO is set to 2 (corresponding to alarm time setting mode). and step 138
After setting CUR to 1, the process moves to step 140.

In step 140, the display corresponding to the value of CUR is blinked. For example, step 1 only after step 138
When it reaches 40, the ALMH display blinks.

Next, in step 142, it is determined whether the switch MO3 is on, and if the result of this determination is affirmative (Y), the process moves to the special setting process shown in FIG.

If the determination result in step 142 is negative (N), the process moves to step 144, and it is determined whether the switch UDS is on. If this judgment result is positive (Y), step 1
4B, the values of the registers corresponding to the cursor position among ALMH and ALMM are respectively increased or decreased within a limited range according to the ARABU or DOWN operation. In accordance with such changes in register values, the display content (alarm time) at the cursor position is also changed.

When the process of step 146 is completed or step 144
If the judgment result is negative (N), step 14
8, it is determined whether the switch CDS is on. If this determination result is affirmative (Y), the process moves to step 150, and C
If UR = 1, add 2 to CUR, if CUR = 2, add C
Set each UR to 1.

When the process of step 150 is completed or step 14B
If the judgment result is negative (N), step 1
The process returns to step 40 and repeats the above process.

According to the processing of steps 140 to 150 described above, the alarm time can be arbitrarily set by appropriately operating the switches DO5 and UDS.

Special Setting Process (FIG. 18) In the special setting process shown in FIG. 19, in step In, the display unit 12 is caused to display as shown in FIG. 3(D). In other words, the contents of MON, DAY, and WEEK are displayed at predetermined positions, and rSP is displayed at the hour position.

Then, the process moves to step 162.

In step IEi2, MDNO is set to 3 (corresponding to special setting mode). Then, the process moves to step 1B4, where the daily daily is derived from MON and DAY and placed in NUM.

Next, in step 168, the value of the register SP(NUM) corresponding to the serial date of NUM is displayed at the minute position.

Then, in step 168, CUR is set to 1, and then the process moves to step 170.

In step 170, the display corresponding to the value of CUR is blinked.
When it reaches 70, the MON display blinks. After this,
The process moves to step 172.

In step 172, it is determined whether switch MO3 is on. If this determination result is positive (Y), the process moves to the volume setting process shown in FIG. 20.

If the determination result in step 172 is negative (N), the process moves to step 174, and it is determined whether the switch UDS is on. If this judgment result is positive (Y), step 1
Moving on to 76.

In step 178, if CUR=1, the value of MON is increased or decreased by 1 in accordance with the up or down operation. Further, if CUR=2, the value of DAY is increased or decreased by 1 in accordance with the up or down operation. According to such a change in the value of MON or DAY, the month or day display is also changed. Then, in either case, derive the through date based on MON and DAY.

Set to NUM. When the NUM value changes in this way, the contents of SP(NUM) are displayed according to the new NUM value.

In step 176, if CUR=3, the value of SP(NUM) is increased or decreased by 1 in accordance with the up or down operation. Such SP(N

Alarm check subroutine (Fig. 23) In the alarm check subroutine of Fig. 23, in step 300, HOU R= A L M H1 MIN=
It is determined whether the four conditions of ALMM, MDNO=O1STPF=0 are satisfied (whether an alarm sound should be generated). If the result of this determination is affirmative (Y), the process moves to step 302, and 1 is set in PLAY. And step 30
Move on to 4.

In step 304, an alarm start subroutine is executed as described later with reference to FIG. and,
Return to the routine of FIG. 22.

As a result, it becomes possible to generate an alarm sound.

If the determination result in step 300 is negative (N), the process moves to step 306, and HOURx80+M I

It is determined whether the three conditions of 0, MDNO-〇, and PLAY=1 are satisfied (whether the alarm sound should be turned off). If the result of this determination is negative (N), the process returns to the routine of FIG. 22.

If the determination result in step 306 is 0 (Y), this means that the stop switch STS has not been turned on even after 30 minutes have elapsed since the start of the alarm sound generation, and the process moves to step 308.

In step 308, PLAY is set to O, and the process moves to step 310, where key-off processing is performed to stop the TG 48 from producing sound.

Return to the routine of FIG. 22.

Alarm start/demon next subroutine In the alarm start/demon next subroutine shown in FIG.
Derive a running date based on and put it in NUM. Then, the process moves to step 322. Here, the process of step 320 is performed only when an alarm starts, and starts from step 322 when a demonstration occurs.

In step 322, various registers are initially set.

That is, TCLK, TBAR, SKP+, 5KP2
, SFR+ and 5FR2 are all set to O,
31 (no rhythm) for RHYH, 15 (no rhythm) for ROTR
(no base) and CLKFLG are set to 1 (reset reservation). Then, the process moves to step 324.

In step 324, it is determined whether the value of the register SP(NUM) corresponding to the serial date of NUM is O (ie, whether it is a unique song).

If the result of this determination is affirmative (Y), the process moves to step 326, and the value of NUM (the serial number of the unique song) is set to NUM2. Further, the determination result in step 324 is negative (
If N), proceed to step 328, and add 386 to the value of SP (NUM) (the serial number of the special song) as NUM.
Theft to 2.

When the processing in step 326 or 328 is completed, the process moves to step 330, where the control variable i is set to 1 and LEN
Set 0 to . Then, the process moves to step 332, and P
Set the start address of the first music data in NTA.

Next, in step 334, it is determined whether i is less than or equal to the value of NUM2-1. A serial track number (any one from 1 to 378) is set in NUM2 at step 326 or 328 described above, and when step 334 is reached for the first time after step 330 when the set value of NUM2 is 2 or more, the determination is made. The result is positive (Y) and the process moves to step 336.

In step 338, the sum of the value of LEN and the number of nodes indicated by the data FAT(i) at address i in the storage unit FAT is set in LEN.

Then, in step 338, the value of i is incremented by 1, and then the process returns to step 334, and the subsequent processes are repeated in the same manner as described above.If the determination result in step 334 is negative (N), the process proceeds to step 340. Move. As a result, L
EN contains a song with a song number one less than the set value of NUM2 (
The cumulative value of surface length data up to the song immediately before the song to be played is set. Note that if NUM2=1, the process moves directly from step 334 to step 340.

In step 340, the value of PNTA (the first address of the first song data) and the value of LEN multiplied by two are added,
Set the added value to PNTA. As a result, PNT
The start address of the song data for the song to be played is set in A. 0 For example, N U M 2 = 387
If so, steps 334-338 result in LEN
is set to the value obtained by accumulating the surface length data of FAT (1) to PAT (3H), and in step 340, PN
The calculation result based on the formula TA+LENX2 is set in PNTA, and PNTA at this time indicates the start address of the song data of the 387th song.

If the process at step 340 fails, the process moves to step 342, and a pointer setting subroutine is executed as described below with reference to FIG. After this, return to the original routine.

Pointer Setting Subroutine (FIG. 25) In the pointer setting subroutine of FIG. 25, in step 350, all KCBUFs are cleared. Then, the process moves to step 352, and a second key process is performed to stop the T G 48 from producing sound. These steps 350 and 352
This process is necessary when the subroutine of FIG. 25 is reached from the read control subroutine of FIG. 27, which will be described later.

Next, in step 354, the value of PNTA plus 4 (the start address of the first part performance data of the song to be played) is set to PNT+. Then, the process moves to step 356, where 4 is added to PNTA and the data FAT at the address indicated by PNTA in the storage section FAT is added.
(PNTA) plus 2 and set the added value to PNT2. Here, FAT (PN
TA) is data representing the number of bytes of the first part,
Adding this to the start address (PNTA+4) of the first part yields the start address of the head data PHD2 of the second part, and further adding 2 to this gives the start address of the head data PHD2 of the second part.

The start address of the second part performance data can be obtained. That is, what is set in PNT2 is the start address of the second heart performance data. After step 356,
The process moves to step 358. In addition, in the following, the storage unit FA・
Assume that the storage area at address X or its storage data indicated by pointers PNTA, PNT+, PNT2, etc. in T is expressed as FAT(X).

In step 358, the time signature/tempo data of PAT CPNTA+1) is read out and entered into DT. Then, the process moves to step 360, where the value of TM (beats per minute) corresponding to the lower 4 bits (tempo level) of DT is set as TEM.
Set to PO. After this, in step 362, the TE
The value of MPO is sent to the tempo clock oscillator 42 as tempo data TD. As a result, the tempo has been set for the song to be played. After step 360, the process moves to step 364.

In step 364, 3 is added to the MSB (O or 1) of the DT.
Set the added value to BEAT. As a result, BE
AT is 3 if the song is in 3 beats, 4 if the song is in 4 beats.
are set respectively. After this, the process moves to step 366.

In step 366, the first
The part tone color data is read out and put into TONE+, and the reference pitch data corresponding to the first part tone range number of FAT(PNT+-) is read out from TBLTR and put into TRN5+. Then, the process moves to step 368.

In step 368, the second
At the same time as reading out the part tone data and putting it into TONE2, reading out the reference pitch data corresponding to the second bart range number of FAT (PNT7-1) from TBLTR and putting it into TR.
Put it in N52. Then, the process moves to step 370.

In step 370, T ON E 1 and T ON
Tone setting processing for T G + and T G 2 is performed based on E 2, respectively, that is, T ON E +
reads the tone parameter information corresponding to the tone number number /′< from the storage unit TPM and sends it to T G +;
Tone parameter information corresponding to the tone number of TONE2 is read from the storage unit TPM and sent to T G 2 .

After this, the routine returns to the original routine.

According to the pointer setting subroutine described above, the tempo, time signature, tone color and range for each part are set for the song to be played based on the data stored in the storage unit FAT. Thereafter, by reading out the performance data of the song from the storage unit FAT, it is possible to automatically perform the song.

Tempo Clock Interrupt Routine (Figure 26) Figure 26 shows:
This shows the tempo clock interrupt routine, which is started for each pulse of the tempo clock signal TCL.

First, in step 380, it is determined whether the value of PLAY is 1, and if the result of this determination is negative (N), the process returns to the main routine. That is, the following processing is performed only when PLAY=1.

If the determination result in step 3800 is affirmative (Y), the process moves to step 382, and a read control subroutine is executed as described later with reference to FIG. Step 38
Step 2 is for reading performance data for each heart from the storage unit FAT, and when this process is finished, step 3
Move to 84.

In step 384, it is determined whether the value of RHYR is 31 (no rhythm). RHYR at step 322 in FIG.
= 31, at step 382, the rhythm type data representing any rhythm number from 0 to 30 is set to RH.
When set to YR, the determination result in step 384 becomes negative (N), and the process moves to step 386.

In step 386, it is determined whether the value of CLKFLG is 1. As described above, when any rhythm number is set to RHY R, CLKFLG=1, so the determination result in step 386 becomes affirmative (Y) and the process moves to step 388. Then, in step 388, CLKFLG
TCLK and T in step 390.
Set O in both BARs. As a result, it becomes possible to read out the rhythm pattern from the beginning of the bar. After step 390, the process moves to step 391A.

In step 391A, it is determined whether the value of SKP+ is O (non-dormant state), and if this determination result is negative (N), the value of SKP+ is decreased by 1 in step 391B. - When the processing of step 391B is completed or step 39
When the determination result of 1A is affirmative (Y), the process moves to step 391G, and it is determined whether the value of 5KP2 is O. If this determination result is negative (N), the process moves to step 391D, and the value of 5KP2 is decreased by 1.

When the process of step 3910 is completed or step 39

The processing of steps 331A to 3910 described above is performed in the 11th
This is necessary in order to synchronize the start of the performance of the other parts with the beginning of the measure of one part when one of the multiple parts starts playing before the other parts as in the song shown in the figure. be. Note that the process for obtaining a pause period longer than half a year during a performance is performed in steps 414 to 4 described below.
It will be held at 20.

From step 382 to step 384 to step 38
At step 6, since CLKFLG=0 in step 388, the determination result becomes negative (N) and the process moves to step 382.

In step 392, RHYR, TBAR and TCLK
Rhythm sound processing is performed based on the storage unit R.
Select the rhythm pattern data corresponding to the RHYH rhythm number in PM, read out the sound source control data from this rhythm pattern data using the value T B A RX 1B + TCLK as an address, and set the rhythm sound source TG.
Send to R. As a result, if the readout sound source control data instructs any of the percussion sound sources to produce sound, a percussion sound signal is generated from that percussion sound source and sent out as a rhythm sound signal. By performing the process of step 382 for each pulse of the tempo clock signal TCL, automatic rhythm performance based on the rhythm pattern becomes possible.

When the process of step 392 is completed or step 384
If the judgment result is positive (Y), step 39

If any root number from O to 11 is set in ROTR when returning to step 382 through steps 388 and 380 as described above, the determination result at step 394 becomes negative (N), and step 338 Move to. In this case, in step 386, in step 388, C
Since LKFLG=0, the 1 judgment result is negative (
N), and the process moves to step 402.

On the other hand, if any root number from 0 to 11 is set to ROTR in step 382 and RHYR=31 for the first time after ROTR=15 in step 322 of FIG. 24, the determination result in step 39B is Positive (Y
), and the process moves to step 398. Step 388 and its integration <In step 400, step 388 described above
and 390, CLKFLG, TCLK and T
BAR is set to O in both cases, thereby making it possible to read out the base pattern from the beginning of the bar. After step 400, steps 391A and 39 are performed as described above.
1C, etc., and returns to step 382.

When step 382 passes through steps 384 and 394 and reaches step 396, step 388 causes CLKF
Since LG=O, the determination result is negative (N) and the process moves to step 402.

In any case, in step 402, RHYR, TB
Bass sound processing is performed based on AR, TCLK, ROTR and TYPE, that is, the R
Select the bass pattern data corresponding to the rhythm number of HYR, and select TBARX from this bass pattern data.
Read out the bass control data using the value 1B+TCLK as an address, and if this bass control data is for the required tone, add the value of ROTH to the bass pitch indicated by the bass control data, and add the added value as appropriate according to the value of TYPE. The modified version (bass pitch data) is used as a bass sound source TG.
Send to B. As a result, a bass sound signal corresponding to the bass pitch data is generated from the sound source T G e. By performing the process in step 402 for each pulse of the tempo clock signal TCL, automatic bass performance based on the bass pattern and chord data becomes possible.

When the process of step 402 is completed or step 384
If the determination result is positive (Y), step 40
Moving on to step 4, the value of TCLK is increased by 1. Then, the process moves to step 40B.

In step 40B, it is determined whether the unit performance section ends at the time signature specified by BEAT. In other words, when the BEAT value is 3 and there is a triple beat, the TCLK value is 6 or 12.
If the BEAT value is 4 (4 beats), the TC
Determine whether the value of LK is 8 or 16. If this determination result is negative (N), the process moves to step 408.

In step 408, the value of TCLK and the value of BEAT are set to 4.
Determine whether the product multiplied by is equal (is it a bundle of measures). If the result of this determination is negative (N), the process returns to the main routine.

If the determination result in step 40B is affirmative (Y), the process moves to step 410, and the value obtained by subtracting the value of TEAH from l is set in TEAH. Therefore, TBAR=0
When TBAR=1, l is set to TBAR, and when TBAR=1, O is set to TBAR. After this, step 4
At step 12, TCLK is set to O and the process returns to the main routine.

When the determination result of the stave 406 is affirmative (Y), the process moves to step 414, and it is determined whether the value of SKP is O (non-dormant state). If this determination result is negative (N), the process moves to step 418, and the value of 5KP1 is decreased by 1. As a result, SKP.

When it reaches 20, the pause period for the first part ends.

When the process of step 41B is completed or step 4】4
If the determination result is positive (Y), step 41
Moving to B, it is determined whether the value of 5KP2 is 0. If this judgment result is negative (N), the process moves to step 420, and the 5KP

As a result, when 5KP2=O, the pause period of the second part ends.

When the process of step 420 is completed or step 418
If the determination result is positive (Y), step 40
8 move.

In step 408, the determination result is negative (N) when TCLK=6 for triple beats and TCLK=8 for quadruple beats, and the process returns to the main routine. Also, the judgment result is positive when TCLK=12 for triple time and TCLK=16 for 4 time.
Y), and the process moves to step 410.

In step 410, the value of TBAR is inverted as described above. Then, in step 412, TCLK is reset to O, and the process returns to the main routine.

Readout Control Subroutine (FIG. 27) In the readout control subroutine of FIG. 27, in step 430, the control variable i is set to 1. Then, the process moves to step 432.

In step 432, the i-th part's half-yearly number register 5

In step 436, the values of the fourth to sixth bits of DT and T
It is determined whether the values of the lower 3 bits of CLK are equal (or whether it is the timing that should be controlled). Here, the lower three bits of TCLK represent the timing within any one of sections 0 to 7.

If the determination result in step 43G is affirmative (Y), the process moves to step 438, and whether the lower 4 bits of DT are all l (
Is it control other than key on/off?). If this determination result is negative (N), it means that the DT data is key-on data or key-off data, and the process moves to step 440.

In step 440, the i-th part's accidental register 5
Determine whether the FRI value is 2 (flat). If this determination result is affirmative (Y), the process moves to step 442, where key code creation (pitch determination) processing is performed, that is, T
The pitch data corresponding to the scale name number of the lower 4 bits of DT is read from BLNT, the value of the reference pitch data of the reference pitch register TRNSi of the i-th part is added to the value of this pitch data, and 1 is calculated from the added value. Create a keycode by subtracting (lowering by a semitone), and convert this keycode to K.
Set to C.

If the determination result in step 440 is negative (N), it means that the image is natural (0) or sharp (1), and the process moves to step 444. In step 444,
A key code creation process that is slightly different from that in step 442 described above is performed, that is, the pitch data corresponding to the scale name number of the lower 4 bits of DT is read from TBLNT, and the value of this pitch data is set to the reference pitch of TRNSi. A key code is created by adding the data value and the SFR+ value, and this key code is set in KC.

In this case, the addition value (T
BLNT value + T RN S r value) becomes the key code value as is if the S F Ri value is O, but 5FR
If the value of i is 1, the key code value is a semitone higher than the key code value.

When the processing in step 442 or 444 is completed, the process moves to step 446, and 5FRi is set to 0.

Y), the process moves to step 450.

In step 450, key-on processing for the i-th part tone source TGi is performed. That is, the key code storage area for two channels of the key code buffer register KCBUFI of the i-th part is checked, and if there is a key code that is the same as that of KC, the key code of KC is stored in the key code storage area of the channel that has the same key code. If there is no key code identical to KC, the key code of KC is assigned to the key code storage area of one of the channels and a musical sound signal corresponding to the key code is generated. let

If the determination result in step 448 is negative (N), it means that the data is key-off data, and step 45
At step 2, key-off processing for TGi is performed.

That is, the key code storage area for two channels of K CB U F i is examined to search for the same key code as KC, and the key code storage area of the channel with the same key code is cleared to stop sound generation.

When the processing in step 450 or 452 is completed, the process moves to step 454, and the value of PNT+ is increased by 1. Then, the process returns to step 432 and the subsequent processes are repeated in the same manner as described above. In this case, if the key-on data is read out to the DT in step 434 and the determination result in step 436 is affirmative (Y), then in step 450 a tone signal corresponding to the key-on data is generated. Therefore, up to two notes can be produced simultaneously for each part.

By the way, if the determination result in step 438 is affirmative (Y), it means that the DT data is control data other than key on/off, and the process moves to step 456.

In step 456, it is determined whether the MSB of DT is 1, and if the result of this determination is affirmative (Y), the process moves to step 458.

In step 458, the 1-data (27th height of control data) of FAT (PNTi + 1) is read out and put into DT. Then, the process moves to step 460, and it is determined how many 0's continue from the MSB in the DT, and the following processes (1) to (5) are performed depending on the number of 0's from the MSB.

(1) When the number of O's from the MSB is O, it means that the DT data is tone data, and step 48
Move on to 2. In step 482, the lower 7 beats and G (timbre numbers) of the DT are stored in the i-th timbre register T ON
Cent on E+. Then, the process moves to step 464, and the tone setting process of T G i is performed based on T ON E i , that is, the tone color parameter information corresponding to the tone color number of TONEi is read from the storage unit TPM and supplied to T G i . As a result, it becomes possible to change and control the tone color for each part during performance.

(2) If the number of O's from the MSB is 1, it means that the DT data is range data, and step 46
Move on to 6. In step 466, the reference pitch data corresponding to the lower six beats (range number) of the DT is stored in the TBLTR.
Read from TRN5. Set to . As a result, it is possible to change the range for each part during performance.

(3) If the number of 0s from the MSB is 2, it means that the DT data is rhythm type data/evening, and the process moves to step 468. In step 468, the lower 5 of the DT
Set the bit (rhythm number) to R)IYR.

As a result, it becomes possible to select a rhythm that matches the music to be performed.

(4) If the number of 0s from the MSB is 3, this means that the DT data is tempo control data, and the process moves to step 470. In step 470, the number of beats corresponding to the lower 4 bits (tempo level) of DT is read from TBLTM and set in TEMPO. And step 4
Moving to 72, the value of TEMPO is sent to the tempo clock oscillator 42 as tempo data TD. As a result, the tempo can be changed during the performance.

(5) If the number of O's from the MSB is 4, this means that the DT data is volume control data, and the process moves to step 474. In step 474, the attenuation amount corresponding to the lower three bits (volume level) of DT is read from TBLVL and set in the i-th volume register VOLi. As a result, it becomes possible to change and control the volume for each part during a performance.

When the above-mentioned steps 464, 466, 468, 472 or 474 are completed, the process moves to step 476, and P
Increase the value of NT by 2. Then, the process returns to step 432 and the subsequent processes are repeated in the same manner as described above.

If the determination result in step 456 is negative (N), the process moves to step 478, and the data of FAT (PNTi +1) is input to DT in the same manner as in step 458 described above. Then, in step 480, the above-mentioned step 4
60, determine how many O's continue from the MSB of DT, and perform the following (1) to (4) depending on the number of 0's from the MSB.
Perform processing like this.

(1) If the number of O's from the MSB is 1, it means that the DT data is chord data, and step 48
Move on to 2. At step 482, the second to fifth bits (root note number) of DT are set to ROTH, and the lower two bits (chord type number) of DT are set to TYPE. As a result, the bass performance ffj that matches the performance song
f u4 becomes possible.

(2) If the number of O's from the MSB is 2, it means that the DT data is rest data, and step 48
Move on to 4. In step 484, the lower 5 bits of DT (
Set the number of half-hanging surfaces) to SKP+. As a result, it becomes possible to set a pause period corresponding to the half-length number of pages for each part.

(3) If the number of O's from the MSB is 5, this means that the DT data is accidental data, and the process moves to step 48G. In step 488, the LSB (
Set SFR to 1 (symbol number) plus 1 (l for sharp, 2 for flat). As a result,
During performance, it is possible to control the pitch according to the accidentals for each part.

(4) If the number of 0s from the MSB is 7, it means that the DT data is end data, and step 4
Move to 88. In step 488, the value of MDNO is O(
(normal display mode), 4 (volume setting mode), or 5 (demonstration performance mode).

If MDNO=0, the process moves to step 490 and T
Increase the value of VOL by 1. In this case, the value of TVOL is limited to 4 or less. After this, in step 482, the second
The pointer setting subroutine is executed as described above with respect to FIG. As a result, after playing the song on the 7th as an alarm sound, it returns to the beginning of the song and lowers the volume level to 1.
It becomes possible to repeat the performance by increasing the level.

When MDNO=4, the process moves to step 492 without passing through step 430, and the pointer setting subroutine shown in FIG. 25 is executed. As a result, the song of the day can be played repeatedly. In this case, the volume level of the performance sound is
TVOL set in steps 200 and 202 in Figure 0
depends on the value of

If MDNO=5, the process moves to step 494 and N
Increase the value of UM by 1. Then, in step 496, the Demon Next subroutine is executed as described above with respect to FIG. As a result, the song of the day when the song of the day has been played will be played.

When the processing of steps 482, 484, 486, 482 or 496 described above is completed, in step 476 the PNTi
After incrementing the value by 2, the process returns to step 432, and the subsequent processes are repeated in the same manner as described above.

The above reason is that after i=1 in step 430, the determination result is affirmative (Y) in both steps 432 and 436.
), if the determination result in step 438 is negative (N), the process moves to step 498 and the value of i is increased by 1. Then, the process moves to step 500, and it is determined whether i is greater than 2. Since i=2 now, the determination result in step 500 is negative (N), and the process returns to step 432. Then, the processing from step 432 onwards is executed for 1==2. That is, the above-mentioned processing is performed for each part of the first and second parts, and it is possible to simultaneously produce up to four notes in total for two parts.

If the determination result in step 438 becomes negative (N) while executing the processes from step 432 after setting i=2, the process moves to step 498 and the value of i is increased by 1.

Thereafter, the determination result at step 500 becomes affirmative (Y), and the process returns to the routine of FIG. 26.

On the other hand, if the determination result in step 432 is negative (N) after setting i=1 (S K P, is not O), it means that the first part is in a dormant state, and step Moving on to 498. Then, after setting i=2 in step 498, the process returns to step 432 via step 500, and 5
If KP2=O, step 434 for the second part.
The following processing is performed, that is, in this case, the processing from step 434 onward is not performed for the first part.

Thereafter, if the determination result in step 436 becomes negative (N) while executing the processes from step 434 onwards for the second part, the second part is processed through steps 498 and 500.
Return to the routine shown in Figure 6.

Also, as another example, when SKP+ = 0, 5KP2
If it is not O, the processing from step 434 onwards is executed for the first part. If the determination result in step 436 is negative (N) during this process, i=2 is set in step 498, and the process returns to step 432 via step 500. At this time, the determination result at step 432 is negative (N), and when i=3 at step 48, the process returns to the routine of FIG. 26 via step 500. Note that if both 5KPI and 5KP2 are not 0, steps 432 and 498 are passed twice before the second

This invention is not limited to the above embodiments, but can be implemented in various modified forms.

For example, a first-order change is possible.

(In this example, the sound source section for each part was configured with a double-tone (2 channels) configuration, but it may also be configured with a single-tone (1 channel). If you do this, the key-off will normally be off, except when a rest expression is required. Data can be omitted and storage capacity can be further reduced.

[Effects of the Invention] As described above, according to the present invention, the pronunciation timing is expressed for each note using the sequential intra-section timing of unit performance sections shorter than 1, and the timing is expressed at the number of unit performance sections. By expressing the period, the following effects can be obtained.

(]) Unlike when expressing the pronunciation timing using the relative time between events, the deviation in the pronunciation timing of one note does not extend to subsequent notes, and the synchronization between the melody and autorhythm does not occur. do not have.

(2) Since the number of bits required to express the timing per note is small, the storage capacity of the performance information storage section can be reduced.

(3) It is possible to play various songs regardless of the length of the pause period, and in particular, even if the song has a pause period of one measure or more, it is possible to memorize the number of unit performance sections corresponding to the pause period. If you do this, there is no need to store small ms information.
