[0002]

2. Description of the Related Art Conventionally, sound sources such as an FM sound source, a harmonic synthesis sound source, and a waveform memory sound source generate musical tone waveforms based on performance data.

For example, in a waveform memory tone generator, when a performance event instructing the start of tone generation of a musical tone occurs, in response thereto, the waveform data of the tone color currently selected from the waveform memory is played at a speed corresponding to the instructed pitch.

And information indicating the rendition style supported by this timbre data, in other words, the type of rendition style used by the natural musical instrument corresponding to this timbre (this information is represented by a "rendition style code" in the present embodiment). Or information indicating what kind of performance information (for example, a series of performance data) should be discriminated from the performance style when the performance style code is assigned to the performance information for which the performance style code is not specified (assigned).

When the tone color data TCD5 is, for example, data for reproducing a tone color of a guitar, a musical tone waveform generated by actually playing a natural musical instrument guitar by various playing methods,
For example, a normal waveform when played normally (played in the usual way), a mute waveform when played mute, a glissando waveform when played glissando, a tremolo waveform when played tremolo, and hammering when hammering on. An on-waveform, a pull-off waveform at the time of pulling-off performance, etc. are sampled, processed as described later, and then stored in the waveform data area 25 as shown in (c). Furthermore, the waveform data area 2
5 also stores other data necessary for reproducing such various waveforms.

When the tone color data TCD5 is data for reproducing a flute tone color, for example,
Musical sound waveforms generated by actually playing a natural musical instrument flute with various playing methods, for example, a normal waveform when played normally, a short waveform when played short, a toggling waveform when played tongue, and a slur waveform when played slur. , The trill waveform when the trill is played is sampled, processed, and then stored in the waveform data area 25 as shown in (d). Then, similarly to (c), other data is also stored in the waveform data area 25.

When the performer specifies a tone color, the tone color data TCDk thus stored in the hard disk is read according to the designated tone color, and the waveform RAM
12 is loaded.

FIG. 4 is a diagram for explaining a method of creating glissando waveform data stored in the waveform data area 25. In the figure, the vertical axis represents the pitch, the horizontal axis represents the time, and the solid line L1 represents the musical tone waveform generated when the performer actually played a guitar from pitch p1 to p2. The time change of the pitch of the raw waveform data thus obtained is shown.

From the raw waveform data sampled in this manner, waveform data (waveform data at time t11-t13 in the example in the figure) is cut out for each note, and a part of the waveform data (waveform at time t11-t12) is cut out. Data) as an attack portion, and the remaining waveform data (waveform data from time t12 to t13) as a loop portion to create glissando waveform data for each note. Therefore, as shown in FIG.
The glissando waveform data is composed of a plurality of glissando waveform data for each note.

Then, for example, when generating a musical sound to which glissando is applied over the pitch designated by the performer, the note starts at a first note, that is, the note having the start pitch designated by the performer, Instructing the pronunciation of the note corresponding to the pitch one note higher than the note being sounded at every predetermined time, and instructing the dumping of the note being sounded, the same processing is performed thereafter, and the set glissando continuation beat is set. Repeat for the period indicated by the number. Here, when the sounding of the note corresponding to the start pitch is instructed, the attack portion of the normal waveform data corresponding to the note, that is, the normal waveform data that is not the glissando waveform data for each note is first read. Then, the reading of the loop portion is started, and this reading is performed from the time when the sounding instruction is given to the next note to the time when a predetermined time α elapses, that is, at the same time, the sound volume dumping instruction of the currently sounding note is issued. (Instruction to control the volume EG to gradually reduce the volume) is made, and the process is repeated until the volume becomes equal to or lower than a predetermined threshold value (may be “0”). On the other hand, during the period from the sounding instruction for the next note to the predetermined time α, the attack portion of the glissando waveform data related to the sounding instruction is read, and then the reading of the loop portion is started. Hereafter, a note corresponding to a pitch one note higher than the note being sounded is instructed at predetermined time intervals, and in response to this, the glissando waveform data (attack part + loop part) corresponding to the note is read out. Is repeated until the pitch (end pitch) at which the specified glissando performance ends. The detailed process will be described later with reference to the flowcharts of FIGS. 12 and 13.

As described above, in the present embodiment, the glissando performance is simulated by connecting the glissando waveform data for each note (however, the normal waveform data is used at the start), so that the adjacent glissando waveform data can be reproduced. In order to improve the connection between the glissando waveform data for each note, the glissando waveform data for each note is an actual glissando waveform for each note (this waveform is a tone waveform of time t1-t2 in the example of the figure). It is created using a part of the glissando waveform for each note, which is one before the shown), that is, a musical tone waveform at time t11-t1.

In the present embodiment, only the glissando waveform data for each note has been described in the direction in which the pitch increases (up direction), but in each direction in which the pitch decreases (down direction). It goes without saying that the glissando waveform data for each note is also created and stored in the waveform data area 25 in the same manner as the above method.

FIG. 5 is a diagram for explaining a method of creating trill waveform data stored in the waveform data area 25. In the figure, the vertical axis represents pitch and the horizontal axis represents time. There is.

In the figure, (a) is a trill raw obtained by sampling a musical tone waveform generated when the performer actually uses a guitar to perform a trill with pulling off and hammering on. The time change of the pitch of the waveform data (solid line L2) is shown. (B) shows pulling-off waveform data created by cutting out from the musical tone waveform shown in (a) the main part of the high pitch and the low pitch, which are alternately generated in the trill performance. The waveform data includes the connection portion from the end of the high pitch waveform that occurs immediately before. (C) shows hammering-on waveform data created by cutting out from the musical sound waveform of (a) the main part of the high pitch out of the high pitch and the low pitch which are alternately generated in the trill performance. The ring-on waveform data includes the connection portion from the end of the bass pitch waveform that occurs immediately before. (D)
Is a musical tone waveform data (a) which is created by cutting out a portion in which the pitch changes from a low pitch to a high pitch to a low pitch from the musical tone waveform of (a), that is, a portion from a certain hammering-on to a subsequent pulling-off. Hereinafter, "down waveform data") is shown, and (e) continues from a musical tone waveform of (a) where a pitch changes from a high pitch to a low pitch to a high pitch, that is, from a pulling-off. The figure shows music waveform data (hereinafter referred to as "up waveform data") created by cutting out parts up to hammering-on.

Pulling-off waveform data Dk (k = 1,
2, 2, ...) are extracted from the sampled trill waveform to form a pulling-off waveform group and stored in the waveform data area 25, as shown in (b). Then, the trill is generated from the pulling-off waveform data Dk by randomly selecting any of the pulling-off waveform data Dk from the pulling-off waveform group to generate a sound, as described later. This is because each pulling-off waveform data Dk has slightly different sounding durations, timbres, and the like. Therefore, it is better to randomly select one of the pulling-off waveforms and generate a sound. This is because it is possible to generate a pulling-off waveform with less habit than when the waveform data Dk is repeatedly read and sounded.

Similarly, a plurality of hammering-on waveform data Uk (k = 1, 2, ...) Are cut out from the sampled trill waveform to form a hammering-on waveform group, as shown in (c). Then, it is stored in the waveform data area 25. Then, the hammering-on waveform data Uk
The trill is generated by the pulling-off waveform data D
Similar to the generation of the trill by k, any one of the hammering-on waveform data Uk is randomly selected from the hammering-on waveform group and sounded. This is because the hammering-on waveform data Uk have subtly different times and timbres for continuing the sound generation.

Hereinafter, a method of generating a musical sound of a trill performance using the pulling-off waveform data Dk and the hammering-on waveform data Uk is referred to as "trill 2".

Down waveform data UDk (k = 1, 2,
As shown in (d), the main part of the trill raw waveform data is the part that changes from the high pitch to the low pitch, and the part that includes the connection part from the end of the low pitch waveform that occurred immediately before that. A plurality of pieces of cut-out waveform data are cut out and formed, and the plurality of pieces of down-waveform data thus created constitute a down-waveform group and are stored in the waveform data area 25. The down waveform data UDk is not limited to this, and one waveform data is selected from each of the hammering-on waveform group and the pulling-off waveform group, and the two selected waveform data are combined in this order. It may be created.

Similarly, the up waveform data DUk (k
= 1, 2, ...), as shown in (e), the trill raw waveform data is connected mainly from the part where the low pitch changes to the high pitch and from the end of the high pitch waveform that occurs immediately before that. A plurality of parts including a part are cut out and created, and a plurality of up waveform data created in this way constitutes an up waveform group and is stored in the waveform data area 25. The up waveform data DUk is not limited to this,
One waveform data may be selected from each of the pulling-off waveform group and the hammering-on waveform group, and the two selected waveform data may be combined in this order to be created.

In the present embodiment, each waveform data UDk or D constituting this down waveform group or up waveform group.
A musical sound of a trill performance (hereinafter referred to as "trill 1") is generated based on Uk. Then, the tone generation by the trill 1 is similar to the tone generation by the trill 2 described above.
This is performed by randomly selecting any one of the waveform data UDk or DUk from the down waveform group or the up waveform group and generating a sound.

Although the trill 1 is generated by using a part of the trill raw waveform data in the same manner as the trill 2 in the present embodiment, the present invention is not limited to this, and the trill playing guitar by picking is used. Sound recording (sampling),
It is also possible to create up-waveform data and down-waveform data and generate musical tones for trill performance based on this.

Next, a method of adding a rendition style code to the performance information created in advance will be described with reference to FIGS. 6 and 7.

FIG. 6 is a block diagram for explaining a method of assigning a rendition style code to performance information. In FIG.
(A) shows a method of automatically adding a rendition style code,
(B) shows a method of manually assigning the rendition style code. 7 is a diagram showing a data format of the performance information after the performance information and the rendition style code are added. In FIG. 7, (a) shows the data format of the performance information, and (b) shows The data format of the performance information after the rendition style code is added is shown.

For example, a plurality of performance information created by a performer or a person other than the performer (hereinafter referred to as "original performance information SMF (Stan
dard MIDI File) ”) is stored in a predetermined area of the hard disk in a file format, from which the performance information is selected according to a player's instruction, and the original performance information secured in a predetermined position of the RAM 5 is stored. Loaded into storage area.

As shown in FIG. 7A, the original performance information SMF includes, for example, initial data such as its title, creation date and time, initial tempo and the like, header data 31 including the capacity of performance information, and a key-on event, for example. It is composed of event data 32 such as a key-off event and velocity data, and duration data 33 indicating the reproduction timing of each event data.

When the rendition style code is automatically added to the original performance information SMF, as shown in FIG. 6A, each data of the original performance information SMF is sequentially read and analyzed, and according to the analysis result. The phrase is divided, and the performance information analysis for determining the rendition based on the divided phrase is performed, and the rendition style code corresponding to the rendition determined as a result of this analysis is output.
Here, in the performance information analysis, the musical score sequence (sequence) represented by the event data and duration data in the original performance information SMF is analyzed based on the performance style analysis control data 22 of the currently designated tone color, According to the analysis result, the sequence is divided (phrase division) for each range determined to be played with the same rendition style, and a rendition style code designating the type of rendition style of each divided phrase is generated. The rendition style code is data indicating the name of the rendition style to be given, event data to which the rendition style should be given (specified), a parameter required to generate a musical tone according to the rendition style,
And the number of beats for continuing the rendition style (for example, when the rendition style is the glissando rendition style, the number of continuous glissando beats)
It is composed of

For example, when the original performance information SMF to be analyzed is created for a guitar, a concrete method of judging the rendition style is as follows.

1) It is judged that the part where the tone generation instructions of two pitches at intervals of a half tone or a whole tone alternately occur is a trill performance.

2) It is determined that the glissando performance is being performed when an instruction to generate a rising or falling pitch that occurs at short time intervals is issued.

The specific method of determining the rendition style when the performance data to be analyzed is created for the flute is as follows.

1) When a sounding instruction of a series of gentle pitches is given, it is judged that the slur is being played.

The rendition style code output in this way is
C (combined) performance information CM combined with the original performance information SMF
F is stored in the C performance information storage area secured at a predetermined position in the RAM 5. Specifically, the rendition style code generated by the performance information analysis is inserted at a predetermined position of the original performance information SMF shown in FIG. 7 (a), and C shown in FIG. 7 (b) is inserted.
Performance information CMF is created. Here, the rendition style code is
The rendition style is stored at a position prior to the event data to be designated, and the type of rendition style to be designated and the event data (a plurality of pieces) to be played by the rendition style in the sequence are designated.

On the other hand, in the case of manually assigning the rendition style code to the original performance information SMF, as shown in FIG. 6B, each data of the original performance information SMF is sequentially read and displayed on the display 2. The musical score is displayed, and the performer judges which part of the musical performance is suitable for playing by looking at the sequence (not shown) of the original musical performance information SMF displayed in the musical score, and as a result, Based on this, the event designating operator (not shown in FIG. 2) is operated to divide a section to be played by one rendition style as a phrase, and the rendition style designating operator (reproduction style switch in FIG. 2) is used to perform the rendition style. When the type is designated, the rendition style code corresponding to the rendition style is output. As a result, a code similar to the rendition style code described with reference to FIG. 6A is output, this rendition style code is combined with the original performance information SMF, and the C performance information CMF is output.
Is stored in the C performance information storage area.

As described above, the rendition style code is data for designating which event in the sequence is to be performed by what kind of rendition style. In addition to this, the time for continuing the designated rendition style is added. It includes long data and parameters for designating more detailed rendition style aspects for each specified rendition style type.

In this parameter, for example, when the natural musical instrument to be simulated is a guitar and the playing method is glissando, a semitone or a whole tone generated at a predetermined time in the glissando performance is raised (or lowered) by one tone. There are "speed parameter" and "curve parameter" that are data that specify how to generate an instruction. "Speed parameter" is data that controls the average value (average speed) of this time interval, and "curve parameter"
Is data for controlling variations such that the time interval is short in the first half of the glissando performance and becomes long in the second half. That is, the “speed parameter” and the “curve parameter” are data that control the time change of the generation density of the sounding instructions that are sequentially generated.

When the rendition style is trill 1, the rendition style data includes a "speed parameter" for controlling the average value of the time intervals of the alternate sounding instructions of the upper and lower pitches generated in the trill performance. Parameters such as “curve parameter” for controlling the variation of the time interval and “up / down parameter” for deciding which waveform data of the above two types of waveform data, the up waveform data and the down waveform data, are used. include.

Further, in the case of playing a guitar, two notes to be played successively may be realized by the choking performance method. Therefore, the second sound produced by choking may be realized by the choking waveform data created from the choking performance waveform. Also in the case of this choking rendition style, the parameters included in the rendition style data include a "speed parameter" and a "curve parameter". The "speed parameter" is data indicating the time from the start of choking to the movement after the choking, and the "curve parameter" is data indicating the locus of the pitch during the change. In order to match the above-mentioned choking waveform data with the "speed parameter" and the "curve parameter", a method called time stretching for expanding and contracting the time axis while keeping the waveform data pitch can be used.

As described above, different types of parameters are set for the rendition style code depending on the natural musical instrument to be simulated and the rendition style to be applied.

Note that these parameters may be set automatically by analyzing the event data itself designated by the rendition style code and according to the time interval or the like, or by the performer (not shown). ) May be used for individual setting.

The control processing method executed by the musical tone generating apparatus configured as described above will be described below first with reference to FIG. 8 and then with reference to FIGS.

FIG. 8 is a block diagram showing an outline of automatic performance processing by the C performance information CMF executed by the musical sound generating apparatus of this embodiment.

As shown in the figure, each data of the C performance information CMF stored in the C performance information storage area is read one by one and timing-decoded. The timing decoding specifically means a process of reading the next data after waiting the timing (time interval) indicated by the duration data when the read data is the duration data. Then, in this processing, the duration data value is set to the header area 3
1 is changed in accordance with the tempo data value stored in 1, and the changed duration data value is decremented by 1 in synchronization with the timer interrupt signal generated by the timer 6, and the value after decrement becomes "0". Until this happens, the reading of the C performance information CMF is prohibited. Instead of changing the duration data value according to the tempo data value, the value to be subtracted by one decrement may be changed according to the tempo data value. Furthermore, instead of changing the duration data value according to the tempo data value, the timer interrupt time may be changed according to the tempo data value.

As a result of the timing decoding in this way, either one of the two types of data, event data and rendition style code data, is read out, and the MIDI event (the event data shown in FIG. 7, that is, the MIDI data, respectively) is read out. This indicates an event that has occurred, but hereinafter, if there is no risk of confusion, it will be abbreviated as "event") or a rendition style code.

When the rendition style code is generated, as described above, the rendition style automatically determined (or manually designated) and the event to which the rendition style should be added (designated) (hereinafter,
Since a "specified event"), various parameters peculiar to the rendition style, and the number of beats for continuing the rendition style are written, the respective data are read out and stored in a buffer secured at a predetermined position of the RAM 5. . Then, among the events that have not yet occurred, search for the event corresponding to the specified event stored in the buffer (hereinafter, the specified event data stored in this buffer is also referred to as “specified event” unless there is a possibility of confusion). Then, a predetermined mark is attached to the event.

When an event occurs, it is determined whether or not the event is the event with the mark, and when it is the event with the mark, the specified event extracting process for extracting the event (that is, the specified event) I do. As a result of this processing, when a designated event is extracted, sound source control by the designated event is not performed, and the rendition style interpretation block determines the type of the rendition style according to the information of the designated event and the rendition style stored in the buffer. The tone generator control is performed so as to generate a musical tone having musical tone change characteristics such as tone color change, tone pitch change, and amplitude change according to.

On the other hand, in the designated event extraction processing, when the designated event is not extracted, that is, when a normal event other than the designated event occurs, the event is used for normal sound source control. For example, when the generated event is the note-on event and is not the designated event, a normal sounding instruction according to the note-on event is given. At this time, the normal tone is generated as one tone without special time processing based on the normal waveform data of FIG. 3 which is not a special rendition style waveform.

FIG. 9 is a flow chart showing the procedure of the C performance information reproducing process for reproducing the C performance information CMF. In this process, the performer operates the C performance information C by the panel operator 1 or the like.
It is activated when an instruction to reproduce the MF is issued.

In FIG. 9, first, various initial settings are made (step S1). For this initial setting, for example,
The C performance information CMF selected by the performer is read from the hard disk and loaded into the C performance information storage area, or the tone color data TCDk used in the C performance information CMF is read from the hard disk and the waveform RAM 1
It can be loaded at a predetermined position of 2 or this C performance information C
It includes a process of setting the tempo according to the tempo data stored in the header of the MF.

Next, the occurrence of each of the following activation factors is checked (step S2).

Activation factor 1: The event has occurred Activation factor 2: The rendition style code has occurred Activation factor 3: The timer 6 has detected the elapse of the set timer time Activation factor 4: Performer Detected a request event other than the activation factors 1 to 3, such as the panel operation device 1 operating the panel operation device 1 to detect the operation event. Activation factor 5: The power switch (not shown) In step S3, which is turned off, it is determined whether or not any of the activation factors 1 to 5 has occurred, and when none of the activation factors 1 to 5 has occurred, the process returns to step S2, When any of the activation factors 1 to 5 occurs, the process proceeds to step S4, and it is determined which activation factor has occurred.

As a result of the determination in step S4, when "activation factor 1" occurs, the process proceeds to step S5, event processing (details of which will be described later with reference to FIG. 10) is executed according to the event, and " When the "activation factor 2" occurs, the process proceeds to step S6, and a rendition style code process (details of which will be described later with reference to FIG. 11) is executed according to the generated rendition style code. In step S7, a timer processing subroutine described later with reference to FIG. 13 is executed. When "activation factor 4" occurs, the process proceeds to step S8, other processing corresponding to the generated request event is performed, and "activation factor 5" is executed. Occurs, the process proceeds to step S9, and a predetermined ending process is executed (step S9).

After the processing in any of steps S5 to S8 is completed, the process returns to step S2 and the above-mentioned processing is repeated, while after the processing in step S9 is completed, the C performance information reproduction processing is executed. finish.

FIG. 10 is a flow chart showing the detailed procedure of the event processing subroutine.

In the figure, first, the event data that is the starting factor is stored in an event data storage area ED secured in a predetermined position of the RAM 5 (hereinafter, the content stored in this area is referred to as "event data ED"). (Step S11).

Next, it is determined whether or not "processed" is designated in the event data ED (step S1).
2). Here, “processed” corresponds to the mark described in FIG. 8, and therefore, the event data for which “processed” is designated is data for which a special rendition style is designated, that is, the designated event. Shows the data.

If "processed" is not designated in the event data ED in step S12, normal tone control that is not a rendition style process is performed according to the event data ED (step S13). For example, event data ED
Is a "note-on event", the sound source (that is, the access control unit 8, the waveform reading unit 9, and the waveform R).
AM 12) is instructed to generate one musical tone based on the normal waveform data, while when the event data ED is a “note-off event”, the corresponding 1 generated in the sound source is generated.
Set the tone to release.

On the other hand, when "processed" is designated in the event data ED in step S12, this event processing subroutine is immediately ended.

FIG. 11 is a flow chart showing the detailed procedure of the rendition style code processing subroutine of step S6.

In the figure, first, the rendition style code data which is the activation factor is stored in a rendition style code data storage area PTC secured at a predetermined position of the RAM 5 (hereinafter, the contents stored in this area will be referred to as "replay style code data PTC"). ")
(Step S21).

Next, the event data whose rendition style is designated by the rendition style code data PTC is searched (step S2).
2). This search is performed on the event data that has not yet occurred (not read) in the C performance information CMF, based on the designated event data stored in the buffer.

As a result of this search (step S23), when the designated event is found, the event is designated as "processed" (step S24), and the rendition style code data P is obtained.
The rendition style interpretation processing subroutine corresponding to the TC is executed (step S25). On the other hand, when the designated event is not found, the rendition style code processing subroutine is immediately ended.

Here, the rendition style interpretation processing subroutine is composed of a plurality of subroutines corresponding to a plurality of unique rendition styles for each selected tone color, and is included in the rendition style interpretation control data 23 of FIG. The designated event, that is, the event data designated by the rendition style code, is C performance information C
There may be multiple events in the MF sequence.
For example, when the specified rendition style is a trill, note-on events of two pitches that are semitones or whole pitches are alternately inserted as event data ED in the sequence. Event is specified. The same applies to the case where the specified rendition style is glissando. In the sequence, all the series of event data to be played (or related to glissando performance) are specified by one rendition style code. And, "interpret the rendition style" means that the tone control according to the rendition style specified by the rendition style code is performed instead of the tone control that was originally performed by the event data specified by the rendition style code. To do.
The content of the event data affects the tone control according to the rendition style code. For example, in the tone control by the rendition style code of the trill, the trill of the two pitches is performed in response to the above-mentioned alternating note-on of the two pitches. Although the speed parameter included in the rendition style code is used in the present embodiment, the speed parameter is not limited to this, and the speed parameter described in the above 2 is used.
You may make it use the average value of the time interval of the pitch note-on.

FIG. 12 is a flow chart showing the procedure of glissando start processing when the guitar tone color is designated. This processing is a part of the rendition style interpretation processing subroutine, and is called and executed only once when the rendition style code data PTC indicates "glissando" in step S25 of FIG.

In FIG. 12, first, a sounding schedule SS is created according to the start pitch and end pitch to which glissando is applied, and the speed parameter and the curve parameter among various parameters stored in the buffer. Yes (step S31). In glissando, a series of ascending tone sequence (or descending tone sequence) events in a sequence are designated by a rendition style code. Music control by Glissando's rendition code is replaced in place of those events. For example, the start pitch and the end pitch correspond to the first pitch and the last pitch of the series of rising pitches (or falling pitches), respectively. Also, the glissando pronunciation rises (or falls) according to the scale of a specific key, so the key of the series of events is determined, and
Determine and control which scale to use. The pronunciation schedule is short phrase data including pronunciation instructions of multiple notes for actually performing the performance style specified by the performance style code, and the pronunciation timing, pitch change, and waveform suitable for each performance style of the phrase. It includes data designating musical tone modes such as changes and volume changes.

Next, according to the pronunciation schedule SS, the pronunciation by the start waveform is started (step S3).
2). Specifically, the pitch indicated by the pronunciation schedule SS,
Waveform data (in the start waveform, the normal waveform data is used instead of the glissando waveform data as described above), the volume EG, etc. are set in the sound source to start the sound generation.

Then, in a series of ascending tone sequences (or descending tone sequences) sequentially designated by the glissando performance, the timing for instructing the pronunciation of the next tone of the above-mentioned tone pitch, that is, the pronunciation of the tone of the tone pitch After setting the time corresponding to the time interval between the timing and the sound generation timing of the next sound in the timer 6 (step S33), the glissando start processing is ended.

In this way, in the sound source, step S3
After the attack portion of the start waveform data designated in 2 is read, the loop portion of the same waveform data is repeatedly read, and the time indicated by the sound generation schedule SS, for example, by the dump start instruction in step S41 described below. During the time until the volume of the sound decreases and falls below a predetermined threshold (becomes inaudible), the musical sound generated based on the start waveform is continuously generated.

FIG. 13 is a flow chart showing the procedure of the glissando continuation timer process which is a part of the timer process subroutine of step S7. The glissando continuation timer process is started when the timer 6 detects the elapse of the time set in step S33.

In the figure, first, the dumping of the musical sound generated immediately before is started (step S41).

Next, the pronunciation of the next tone is started according to the pronunciation schedule SS (step S42). Specifically, in the next note indicated by the pronunciation schedule SS, that is, in the series of ascending notes (or descending notes) sequentially designated in the glissando performance, the note corresponds to the note next to the last note to be pronounced. Waveform data in the glissando waveform data (1 composed of the attack portion and the loop portion described in FIG. 4)
One waveform data) is designated, and in the same manner as in step S32, the designated waveform data and the pitch, volume EG, etc. indicated by the sounding schedule SS are set as a sound source, and the sounding is started.

Then, it is judged whether or not the pitch of the musical tone being currently sounded is the end pitch (step S43), and when it is not the end pitch, that is, the glissando waveform to be generated (for each note to be read out). If the glissando waveform still remains, the continuation timer is set in accordance with the tone generation schedule SS (step S44) in the same manner as in step S33, and then the glissando continuation timer process is terminated.

On the other hand, if it is determined in step S43 that the tone pitch of the tone currently being sounded is the end tone pitch, this glissando continuation timer processing is immediately ended.

The stroke rendition style can be simulated by changing a part of the above method for simulating the glissando rendition style. Specifically, the pronunciation schedule SS of the step S31.
Is changed to a stroke playing style so that the time pattern of the sounding timing becomes denser than that of the arpeggio, and the step S4 is performed.
The dump process 1 is deleted.

FIG. 14 is a flow chart showing the procedure of the trill 1 start processing when the guitar tone color is designated. This processing is a part of the rendition style interpretation processing subroutine in step S6, and is called and executed only once when the rendition style code data PTC indicates "trill 1" in step S25 in FIG.

In the figure, first, it is judged whether or not the player has designated the up direction as the direction of the trill (step S51).
A waveform group corresponding to the speed parameter is selected from the down waveform group described in (d) (step S5).
2) On the other hand, when the up direction is designated, as shown in FIG.
A waveform group corresponding to the speed parameter is selected from the up waveform group described in (e) (step S53).

In the following step S54, step S52
Alternatively, the trill 1 start processing is terminated after the start of the sound generation of the start waveform of the waveform group selected in S53.

FIG. 15 is a flow chart showing the procedure of the trill 1 continuation timer process which is a part of the timer process subroutine of step S7. The trill 1 continuation timer process is started when the timer 6 detects the elapse of a predetermined time, that is, the time at which the reading of the start waveform instructed to be sounded in the trill 1 start process of FIG. 14 is finished.

In the figure, first, it is judged whether or not it is within the designated duration, that is, the duration for continuing the trill 1 performance (step S61), and when the duration has elapsed, the trill 1 continuation timer is immediately started. On the other hand, while the processing is ended, if it is within the duration, the process proceeds to step S62.

In step S62, a random number is generated. In step S63, a waveform is selected from the selected waveform group in accordance with the random number. In step S64, sound generation by the selected waveform is started, and then the trill 1 The continuation timer process ends.

FIG. 16 is a flow chart showing the procedure of the trill 2 start processing when the guitar tone color is designated. This processing is a part of the rendition style interpretation processing subroutine in step S6, and is called and executed only once when the rendition style code data PTC indicates "trill 2" in step S25 in FIG.

In the figure, first, the pulling-off (upper) waveform group described in FIG. 5B is selected (step S
71), and then the hammering-on (lower) waveform group described in FIG. 5C is selected (step S72).

Then, it is determined whether or not the performer has designated the up direction as the initial direction of the trill (step S
73), when the down direction is designated, "0 (down direction)" is set to the trill direction flag U indicating "1" that the trill direction is the up direction (step S73), and the upper waveform A start waveform is selected from the inside (step S75).

On the other hand, if it is determined in step S73 that the performer specifies the up direction as the initial direction of the trill, the trill direction flag U is set to "1 (up direction)" (step S76), and the lower waveform is set. The start waveform is selected from among these (step S77).

In the following step S78, the above-mentioned step S
After starting the sound generation with the start waveform selected in 75 or S77, the trill 2 start processing is ended.

FIG. 17 is a flow chart showing the procedure of the trill-2 continuation timer process which is a part of the timer process subroutine of step S7. The trill-2 continuation timer process is started when the timer 6 detects the elapse of a predetermined time, that is, the time at which the reading of the start waveform instructed to be sounded in the trill-2 start process of FIG. 14 is finished.

In the figure, first, it is judged whether or not it is within the designated duration time, that is, the duration for continuing the trill 2 performance (step S81). When the duration time has elapsed, the trill 2 continuation timer is immediately started. While ending the processing, if it is within the continuation time, the process proceeds to step S82 to generate a random number.

In a succeeding step S83, it is determined whether or not the value of the trill direction flag U is "1", and when U = 0, that is, when the trill direction is the down direction,
The start waveform is selected from the lower waveform according to the generated random number (step S84). On the other hand, when U = 1, that is, when the trill is in the up direction, the start waveform is selected from the upper waveform according to the generated random number. A selection is made (step S85).

Next, the sound generation with the waveform selected in step S84 or S85 is started (step S86),
After inverting the value of the trill direction flag U (U ← / U), the present trill 2 continuation timer processing is ended.

As described above, in the present embodiment, the musical tone played by the special rendition peculiar to the natural musical instrument is sampled, processed and stored in the memory such as the hard disk, and the natural tone data is stored based on the stored musical tone data.

It should be controlled.

The related information and operation programs for realizing the musical tone generating apparatus of this embodiment are stored in the storage device such as the hard disk, and the CPU 3 stores them in RA.
It is configured to use after reading to M5.
