Description

  The present invention relates to a musical sound waveform data creation method and a storage medium for generating a musical sound waveform based on performance data.

  Conventionally, sound sources such as an FM sound source, a harmonic synthesis sound source, and a waveform memory sound source generate a musical sound waveform based on performance data.

  For example, in the case of a waveform memory sound source, when a performance event instructing the start of musical sound occurs, the waveform data of the currently selected tone is read from the waveform memory at a speed corresponding to the instructed pitch.

Therefore, in the case of a natural musical instrument, the tone color of the musical tone naturally changes according to the selected playing method, but the change in the tone color cannot be expressed faithfully by the conventional sound source.

  FIG. 3 is a diagram showing an example of a plurality of tone color data TCDk stored in the hard disk of the disk drive 10 and its data format. In the figure, (a) shows a state in which a plurality of timbre data TCDk (k = 1,...) Are stored, (b) shows the data format of one timbre data TCD5, and (c ) Shows an example of various waveform data obtained by sampling, processing, and storing musical sounds played by various guitar playing methods when the timbre data TCD5 is a guitar timbre. In the case of a timbre, an example of waveform data stored in the same manner as (c) is shown.

  Each timbre data TCDk has a data format similar to that of the timbre data TCD5 shown in (b), and includes a header area 21 for storing a timbre name, a data capacity, and the like, and a performance method supported by the timbre data, in other words. Information indicating the type of rendition style used by the natural musical instrument corresponding to this tone color (this information is expressed as “replay style code” in the present embodiment), or performance information for which no rendition style code is specified (given) A rendition style analysis (or designation) control data area 22 for storing information indicating what kind of performance information (for example, a series of performance data) is appropriate to be distinguished from the rendition style when giving a rendition style code; When a performance code is specified (given) in the performance information, it is determined how each parameter of the performance information is processed and controlled according to the performance code.

  When the timbre data TCD5 is, for example, data for reproducing the timbre of a guitar, a musical sound waveform generated by actually playing a natural musical instrument guitar with various performance techniques, for example, a normal performance (played with a normal performance style) Normal waveform when playing, mute waveform when playing mute, glissando waveform when playing glissando, tremolo waveform when playing tremolo, hammering on waveform when playing hammering on, pulling off waveform when playing off pulling Are sampled and processed as described later, and then stored in the waveform data area 25 as shown in FIG. Further, the waveform data area 25 stores other data necessary for reproducing such various waveforms.

  When the timbre data TCD5 is, for example, data for reproducing a flute timbre, a musical sound waveform generated by actually playing a natural instrument flute with various performances, for example, a normal waveform when a normal performance is performed, A short waveform when a short sound is played, a tongue waveform when a tongue is played, a slur waveform when a slur is played, a trill waveform when a trill is played, etc. are sampled and processed, as shown in (d). Stored in the data area 25. In the same manner as (c), other data is also stored in the waveform data area 25.

  Each tone color data TCDk stored in the hard disk in this way is read according to the designated tone color and loaded into the waveform RAM 12 when the performer designates the tone color.

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

  Waveform data (waveform data at time t11-t13 in the example shown in the figure) is cut out from the raw waveform data sampled in this way for each note, and a part of the waveform data (waveform data at time t11-t12) is extracted. Using the remaining waveform data (waveform data at time t12-t13) as a loop portion as the attack portion, glissando waveform data for each note is created. Therefore, the glissando waveform data of FIG. 3 (c) is composed of a plurality of glissando waveform data for each note.

  For example, when generating a musical tone with a glissando between the pitches designated by the performer, the sounding is started with the first note, that is, the note with the start pitch designated by the performer, and is performed at predetermined intervals. In addition to instructing to pronounce a note corresponding to a note that is one note higher than the note being pronounced, to instruct to dump the note that is being pronounced, the same processing is indicated by the set glissando continuation number of beats. Repeat for a period. Here, when the pronunciation of the note corresponding to the start pitch is instructed, the normal waveform data corresponding to the note, that is, the attack portion of the normal waveform data which is not the glissando waveform data for each note is first read out. Subsequently, reading of the loop portion is started, and this reading is performed until a predetermined time α elapses from the time when the sounding instruction for the next note is performed, that is, at the same time as this, a sound volume dumping instruction for the currently sounding note is performed. (Instruction for controlling the volume EG to gradually reduce the volume) is made, and the process is repeated until the volume falls below a predetermined threshold value (may be “0”). On the other hand, during the period from the sounding instruction to the next note until the predetermined time α, the attack part of the glissando waveform data related to the sounding instruction is read, and then the reading of the loop part is started. Thereafter, the sound generation of a note corresponding to a pitch one note higher than the note being sounded at a predetermined time is instructed, and in response to this, the glissando waveform data (attack portion + loop portion) corresponding to the note is read. And repeated until the pitch (end pitch) at which the specified glissando performance is completed. This detailed processing will be described later with reference to the flowcharts of FIGS.

  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). In order to improve the connection between the glissando waveform data, the glissando waveform data for each note is the actual glissando waveform for each note (this waveform is shown as a musical tone waveform at time t1-t2 in the example of the figure). It is created using a part of the glissando waveform for each previous note, that is, a musical sound waveform at time t11-t1.

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

  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 indicates pitch and the horizontal axis indicates time.

  In the figure, (a) shows trill raw waveform data (sampled) obtained by sampling musical sound waveforms generated when a performer actually performs a trill performance with pulling-off and hammering-on using a guitar. The time change of the pitch of the solid line L2) is shown. (B) shows the pull-off waveform data created by cutting out the high pitches and low pitches generated alternately from the musical tone waveform of (a) as the main, and the respective pull-offs. The waveform data includes a connection portion from the end of the waveform of the high pitch generated immediately before each. (C) shows the hammering-on waveform data created by cutting out the high-pitched pitch portion and the high-pitched pitch portion alternately generated by the toll performance from the musical sound waveform of (a). Each ring-on waveform data includes a connection portion from the end of the low pitch waveform generated immediately before. (D) is a musical tone created by cutting out from the musical sound waveform of (a) the portion where the pitch changes from low pitch to high pitch, that is, the portion from a certain hammering-on to the subsequent pull-off. Waveform data (hereinafter referred to as “down waveform data”) is shown, and (e) shows from the musical tone waveform of (a) where the pitch changes from high pitch to low pitch, that is, from a certain pull-off. The musical tone waveform data (hereinafter referred to as “up-waveform data”) created by cutting out the subsequent part until hammering-on is shown.

  A plurality of pull-off waveform data Dk (k = 1, 2,...) Are cut out from the sampled toll waveform as shown in FIG. Stored. Then, generation of a trill by the pull-off waveform data Dk is performed by randomly selecting one of the pull-off waveform data Dk from the pull-off waveform group and generating a sound. This is because each pull-off waveform data Dk has a slightly different sounding time, tone color, etc., so that one of the pull-off waveforms is selected by randomly selecting from the pull-off waveform group. This is because it is possible to generate a pull-off waveform with less wrinkles than when the waveform data Dk is repeatedly read out and generated.

  Similarly, as shown in (c), 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. Stored in the waveform data area 25. Then, the generation of the trill by the hammering-on waveform data Uk is performed by randomly selecting any of the hammering-on waveform data Uk from the hammering-on waveform group in the same manner as the generation of the trill by the pulling-off waveform data Dk. This is done by making them pronounce. This is because each hammering-on waveform data Uk has a slightly different sounding time and tone color.

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

  The down waveform data UDk (k = 1, 2,...), As shown in (d), is mainly the portion where the treble raw waveform data changes from high pitch to low pitch, and the low pitch generated just before that. A plurality of portions including the connection portion from the end of the waveform are cut out and created, and the plurality of down waveform data created in this way constitutes a down waveform group and is stored in the waveform data area 25. The down waveform data UDk is not limited to this. 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. You may make it create.

  Similarly, as shown in (e), the up waveform data DUk (k = 1, 2,...) Is generated immediately before the main portion of the trill raw waveform data that changes from low pitch to high pitch. A plurality of portions including the connection portion from the end of the high pitch waveform are cut out and created, and the plurality of up waveform data created in this way constitutes an up waveform group in the waveform data area 25. Stored. Note that the up waveform data DUk is not limited to this, and one waveform data is selected from each of the pulling off waveform group and the hammering on waveform group, and the two selected waveform data are combined in this order. You may make it do.

  In the present embodiment, a musical sound of a trill performance (hereinafter referred to as “trill 1”) is generated based on each waveform data UDk or DUk constituting the down waveform group or the up waveform group. The musical sound is generated by the trill 1 in the same manner as the musical sound is generated by the trill 2 by randomly selecting one of the waveform data UDk or DUk from the down waveform group or the up waveform group and generating a sound. .

  In the present embodiment, the trill 1 is generated by using a part of the trill raw waveform data in the same manner as the trill 2. However, the present invention is not limited to this, and the guitar sound of the trill performance by picking is recorded. (Sampling) may be used to create up waveform data and down waveform data, and to generate a musical sound for a trill performance.

  Next, a method for assigning performance style codes to performance information created in advance will be described with reference to FIGS.

  FIG. 6 is a block diagram for explaining a method for assigning performance style codes to performance information, in which (a) shows a method for automatically assigning performance style codes, and (b) shows performance style codes. It shows how to apply manually. FIG. 7 is a diagram showing a data format of performance information after performance information and performance codes are added. In FIG. 7, (a) shows a data format of performance information, and (b) shows a data format of performance information. The data format of the performance information after the performance style code is given is shown.

  For example, a plurality of pieces of performance information (hereinafter referred to as “original performance information SMF (Standard MIDI File)”) created by a performer or a person other than the performer is stored in a predetermined area of the hard disk in a file format. The performance information is selected in accordance with the player's instruction and loaded into the original performance information storage area secured at a predetermined position in the RAM 5.

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

  When the performance code is automatically assigned 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 the phrase is divided according to the analysis result. Then, performance information analysis for determining a performance style based on the divided phrases is performed, and a performance style code corresponding to the performance style determined as a result of this analysis is output. Here, the performance information analysis is performed by analyzing a sequence of musical scores represented by event data and duration data in the original performance information SMF based on the rendition style analysis control data 22 of the currently designated tone, In accordance with the analysis result, the sequence is divided (phrase division) for each range determined to be played in the same performance style, and a performance style code designating the type of performance style of the divided phrases is generated. The rendition style code includes data indicating the name of a rendition style to be assigned, event data to which the rendition style is to be given (designated), parameters necessary for generating a musical sound according to the rendition style, and the number of beats for continuing the rendition style ( For example, when the playing style is the glissando playing style, the glissando continuous beat number) is used.

  For example, when the original performance information SMF to be analyzed is created for a guitar and a guitar tone color is designated, a specific method for determining a playing style is as follows.

  1) It is determined that the portion where the sound generation instructions of two pitches of the semitone or the whole tone interval are alternately generated is the trill performance.

  2) When a sounding instruction for a rising or falling pitch occurring at a short time interval is given, it is determined that the performance is a glissando performance.

  The performance data to be analyzed is created for the flute, and the specific method of determining the playing method when the flute tone is designated is as follows.

  1) When a pronunciation instruction for a gentle series of pitches is given, it is determined that the performance is a slur performance.

  The performance style code output in this way is combined with the original performance information SMF, and stored as C (combined) performance information CMF in a C performance information storage area secured at a predetermined position in the RAM 5. Specifically, the performance style code generated by the performance information analysis is inserted into a predetermined position of the original performance information SMF shown in FIG. 7A, and the C performance information CMF shown in FIG. 7B is created. Here, the rendition style code is stored at a position before the event data for which the rendition style is to be specified, and indicates the type of rendition style to be specified and the designation of the event data (s) to be played with that rendition style in the sequence. Do.

  On the other hand, when a performance method code is manually added to the original performance information SMF, each data of the original performance information SMF is sequentially read and displayed on the display 2 as shown in FIG. 6B. The performer determines which part of the original performance information SMF sequence (not shown) displayed on the musical score is suitable for performing by which performance method, and based on the result, An event designation operator (not shown in FIG. 2) is operated to divide a section to be played in one performance style as a phrase, and the type of performance technique is selected by a performance style designation operator (a performance switch in FIG. 2). When specified, a performance style code corresponding to the performance style is output. As a result, a chord similar to the performance chord described in FIG. 6A is output, and this performance chord is combined with the original performance information SMF and stored as C performance information CMF in the C performance information storage area. .

  As described above, the performance style code is data specifying which event in the sequence is to be played in what kind of performance style. In addition to this, the performance style code is data of the length of time for which the specified performance style is continued. In addition, it includes a parameter for designating a more detailed performance style for each designated performance style type.

  In this parameter, for example, when the natural musical instrument to be simulated is a guitar, and the playing style is glissando, a sound generation instruction that is higher (or lower) by a semitone or a whole tone generated every predetermined time in the glissando performance is generated. There are “speed parameter” and “curve parameter”, which are data for designating the method. “Speed parameter” is data that controls the average value (average speed) of this time interval, and “curve parameter” varies such that the time interval is short in the first half of the glissando performance period and longer in the second half. This is the data that controls That is, the “speed parameter” and the “curve parameter” are data for controlling the temporal change in the generation density of the sound generation instructions that are sequentially generated.

  Further, when the performance style is Trill 1, the performance style data includes a “speed parameter” for controlling the average value of the time intervals of alternating sound generation instructions of upper and lower pitches generated in the Trill performance, Parameters such as “curve parameter” for controlling variation and “up / down parameter” for determining which waveform data to use from the two types of waveform data, up waveform data and down waveform data, are included. Yes.

  Furthermore, in the case of playing a guitar, two notes that are played in succession may be realized by a choking technique. Therefore, the second sound generated by the choking may be realized by the choking waveform data created from the choking performance waveform. Also in this choking technique, the parameters included in the performance data include “speed parameter” and “curve parameter”. The “speed parameter” is data indicating the time from the start of choking to moving to the sound after choking, and the “curve parameter” is data indicating the locus of the pitch during the change. In order to match the choking waveform data with the “speed parameter” and the “curve parameter”, it is possible to use a technique called time stretching that expands and contracts the time axis while maintaining the pitch of the waveform data.

  In this way, different parameters are set for the performance style code depending on the natural musical instrument to be simulated and the performance style to be applied.

  These parameters may be automatically set according to the event occurrence time interval or the like by analyzing the event data itself specified by the rendition style code and the duration data between them. You may make it set separately using an operation element (not shown).

  The control processing method executed by the musical tone generation apparatus configured as described above will be described in more detail 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 tone generation apparatus of the present embodiment.

  As shown in the figure, each piece of data of the C performance information CMF stored in the C performance information storage area is read one by one and subjected to timing decoding. Specifically, the timing decoding refers to a process of reading the next data after waiting for a timing (time interval) indicated by the duration data when the read data is duration data. In this process, the duration data value is changed in accordance with the tempo data value stored in the header area 31, and the duration data value after the change is synchronized with a timer interrupt signal generated by the timer 6. This is performed by decrementing one by one and prohibiting reading of the C performance information CMF until the value after decrement becomes “0”. 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 interruption time may be changed according to the tempo data value.

  As a result of the timing decoding in this way, one of the two types of data, event data and rendition style code data, is read out, and the MIDI event (the event data in FIG. 7, ie, the event generated by the MIDI data) is read out. Hereinafter, when there is no possibility of confusion, an event is abbreviated as “event”) or a rendition style code is generated.

  When a rendition style code is generated, the rendition style code includes, as described above, an automatically determined (or manually designated) rendition style, an event to which the rendition style should be assigned (designated) (hereinafter referred to as “designated event”), Since various unique parameters and the number of beats for continuing the performance are written, each data is read out and stored in a buffer secured at a predetermined position of the RAM 5. Then, among events that have not yet occurred, a search is made for an event corresponding to a specified event stored in the buffer (hereinafter, the specified event data stored in this buffer is also referred to as a “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 an event with the mark. If the event is an event with a mark, a specified event extraction process is performed to extract the event (that is, a specified event). When a specified event is extracted as a result of this processing, the type of rendition is not performed according to the rendition style interpretation block and the rendition style stored in the buffer by the rendition style interpretation block without performing sound source control according to the specified event. The sound source is controlled so as to generate a musical tone having musical tone change characteristics such as a timbre change, a pitch change, and an amplitude change in accordance with the tone.

  On the other hand, when a designated event is not extracted in the designated event extraction process, that is, when a normal event that is not a designated event occurs, the event is used for normal sound source control. For example, when the generated event is a note-on event and is not a designated event, a normal sound generation instruction corresponding to the note-on event is performed. At this time, the normal musical tone is generated as one musical tone without special time processing or the like based on the normal waveform data of FIG. 3 which is not a special performance waveform.

  FIG. 9 is a flowchart showing the procedure of the C performance information reproduction process for reproducing the C performance information CMF. This process is started when the performer instructs the reproduction of the C performance information CMF by the panel operator 1 or the like. The

  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 timbre data TCDk used in the C performance information CMF is read from the hard disk. The processing includes reading and loading the waveform RAM 12 at a predetermined position, and setting the tempo according to the tempo data stored in the header of the C performance information CMF.

  Next, the occurrence 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 that the set timer time has elapsed Activation factor 4: The player has operated the panel A request event other than the activation factors 1 to 3 and 5 is detected, such as the operation event detected by operating the child 1 etc. Activation factor 5: The power switch (not shown) is turned off. In the following step S3, it is determined whether or not any of the activation factors 1 to 5 has occurred. If none of the activation factors 1 to 5 has occurred, the process returns to step S2, while the activation factor 1 When any one of? 5 occurs, the process proceeds to step S4 to determine 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, and event processing (details will be described later with reference to FIG. 10) corresponding to the generated event is executed. ”Occurs, a performance style code process (details will be described later with reference to FIG. 11) corresponding to the generated performance style code is executed. If“ activation factor 3 ”occurs, the process proceeds to step S7. , A timer processing subroutine, which will be described later with reference to FIG. 13, is executed, and when “activation factor 4” occurs, the process proceeds to step S8, and other processing corresponding to the generated request event is executed, and “activation factor 5” occurs. If so, the process proceeds to step S9 to execute a predetermined end process (step S9).

  After any of the processes in steps S5 to S8 is completed, the process returns to step S2 and repeats the above-described process. On the other hand, after the process in step S9 is completed, the C performance information reproduction process is terminated.

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

  In the figure, first, event data that has become an activation factor is stored in an event data storage area ED (hereinafter referred to as “event data ED”) secured in a predetermined position of the RAM 5. (Step S11).

  Next, it is determined whether or not “processed” is specified in the event data ED (step S12). Here, “processed” corresponds to the mark described with reference to FIG. 8. Therefore, the event data for which “processed” is designated is data for which a special rendition is designated, that is, the designated event. Data are shown.

  If “processed” is not designated in the event data ED in step S12, normal musical tone control that is not rendition processing is performed according to the event data ED (step S13). For example, when the 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 RAM 12) is instructed to generate one musical tone based on the normal waveform data. When the data ED is a “note-off event”, the corresponding one musical sound generated in the sound source is set to the release state.

  On the other hand, if “processed” is designated in the event data ED in step S12, this event processing subroutine is immediately terminated.

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

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

  Next, event data designated by the performance style by the performance style code data PTC is searched (step S22). This search is performed based on the designated event data stored in the buffer for event data not yet generated (not read) in the C performance information CMF.

  As a result of this search (step S23), when a designated event is found, the event is designated as “processed” (step S24), and a performance style interpretation processing subroutine corresponding to the performance style code data PTC is executed (step S25). If the designated event is not found, the performance style code processing subroutine is immediately terminated.

  Here, the rendition style interpretation processing subroutine is constituted by 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 specified event, that is, the event data specified by the rendition style code may be a plurality of events in the C performance information CMF sequence. For example, when the specified rendition style is a trill, note-on events of two pitches of semitones or full-tone intervals are alternately included in the sequence as event data ED. Events are specified. Similarly, when the designated performance style is a glissando, all the series of event data to be played (or related to the glissando performance) in the sequence is designated by one glissando performance code. And “interpret the rendition” means that instead of the musical sound control originally performed by the event data specified by the rendition code, the musical sound control according to the rendition type specified by the rendition code is performed. To do. The content of the event data affects the tone control according to the performance code. For example, in the musical tone control by the playing method code of the trill, the two-pitch trill is performed in response to the above-described two-pitch note-on. In the present embodiment, the speed parameters included in the rendition style code are used. However, the present invention is not limited to this, and the average value of the two-pitch note-on time intervals may be used.

  FIG. 12 is a flowchart showing the procedure of glissando start processing when a guitar tone is designated. This process is a part of the rendition style interpretation 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 pronunciation 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 the various parameters stored in the buffer (steps). S31). In the glissando, a series of ascending (or descending) strings of events in a sequence are specified by a rendition style code. The performance style code in the musical tone control by the glissando performance style 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 pitch (or falling pitch), respectively. Further, since the glissando sound rises (or descends) according to a scale of a specific key, the key of the series of events is determined and which scale is used is controlled and controlled. The pronunciation schedule is short phrase data including pronunciation instructions for multiple notes for actually performing the performance specified by the performance code, and the sound generation timing, pitch change, and waveform suitable for each performance over the period of the phrase It includes data that specifies musical tone modes such as changes and volume changes.

  Next, sound generation by the start waveform is started according to the sound generation schedule SS (step S32). Specifically, the pitch, waveform data (in the start waveform, normal waveform data is used instead of the glissando waveform data as described above), volume EG, etc. are set in the sound source. , Start its pronunciation.

  Then, in a series of ascending tone strings (or descending tone strings) sequentially specified in the glissando performance, the timing for instructing the pronunciation of the next sound after the start pitch, that is, the start timing of the start pitch and its timing After the time corresponding to the time interval with the sound generation timing of the next sound is set in the timer 6 (step S33), the glissando start process is terminated.

  In this manner, in the sound source, after the attack portion of the start waveform data instructed in step S32 is read, the loop portion of the waveform data is repeatedly read and the time indicated by the pronunciation schedule SS, for example, next The musical sound generated based on the start waveform is continuously generated for the time from when the volume of the sound decreases to a level below a predetermined threshold (no longer heard) by the dump start instruction in step S41 to be described.

  FIG. 13 is a flowchart showing the procedure of glissando continuation timer processing which is a part of the timer processing subroutine of step S7. This 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 next sound generation is started in accordance with the sound generation schedule SS (step S42). Specifically, in the next sound indicated by the sound generation schedule SS, that is, in the series of ascending sound strings (or descending sound strings) sequentially designated by the glissando performance, it corresponds to the sound next to the sound instructed to sound last. The waveform data in the glissando waveform data (one waveform data composed of the attack portion and the loop portion described in FIG. 4) is designated, and the designated waveform data and the sound generation schedule are designated in the same manner as in step S32. The pitch, volume EG, and the like indicated by SS are set as the sound source and the sound generation is started.

  Then, it is determined whether or not the pitch of the tone currently being generated is the end pitch (step S43). When the pitch is not the end pitch, that is, the glissando waveform to be generated (the glissando waveform for each note to be read). Is still left, the continuation timer is set in accordance with the sound generation schedule SS (step S44), and the glissando continuation timer process is terminated.

  On the other hand, if it is determined in step S43 that the pitch of the tone currently being generated is the end pitch, the glissando continuation timer process is immediately terminated.

  In addition, when simulating a stroke performance method, it can be performed by changing a part of the above method for simulating a glissando performance method. Specifically, the sound generation schedule SS in step S31 is changed to that for stroke performance, the time pattern of sound generation timing is made denser than the arpeggio, and the dump process in step S41 is deleted.

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

  In the figure, first, it is determined whether or not the performer has designated the up direction as the direction of the trill (step S51), and when the down direction is designated, it is determined from the down waveform group described with reference to FIG. Then, a waveform group corresponding to the speed parameter is selected (step S52). On the other hand, when the up direction is designated, a waveform group corresponding to the speed parameter is selected from the up waveform group described in FIG. Select (step S53).

  In the subsequent step S54, after the sound generation by the start waveform of the waveform group selected in step S52 or S53 is started, this Trill 1 start process is ended.

  FIG. 15 is a flowchart 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 to finish reading the start waveform instructed to generate sound in the Trill 1 start process of FIG.

  In the figure, first, it is determined whether or not it is within a designated duration, that is, within the time to continue the Trill 1 performance (step S61). When the duration has elapsed, the Trill 1 duration timer process is immediately terminated. On the other hand, when 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 according to the random number. In step S64, after the sound generation by the selected waveform is started, this trill 1 continuation timer processing is performed. Exit.

  FIG. 16 is a flowchart showing the procedure of the Trill 2 start process when a guitar tone is designated. This process is a part of the rendition style interpretation subroutine at step S6. When the rendition style code data PTC indicates “Trill 2” at step S25 in FIG. 11, it is called and executed only once.

  In the figure, first, the pull-off (lower) waveform group described in FIG. 5B is selected (step S71), and then the hammering-on (upper) 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 S73). When the down direction has been designated, it is determined that “1” indicates that the direction of the trill is the up direction. “0 (down direction)” is set to the toll direction flag U shown (step S73), and a start waveform is selected from the lower waveforms (step S75).

  On the other hand, if it is determined in step S73 that the performer has designated the up direction as the initial direction of the trill, “1 (up direction)” is set in the trill direction flag U (step S76), and the upper waveform is selected. A start waveform is selected (step S77).

  In the subsequent step S78, after the sound generation by the start waveform selected in the above step S75 or S77 is started, the present Trill 2 start process is ended.

  FIG. 17 is a flowchart 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 to finish reading the start waveform instructed to generate sound in the Trill 2 start process of FIG.

  In the figure, first, it is determined whether or not it is within a designated duration, that is, within the time to continue the Trill 2 performance (step S81). When the duration has elapsed, the Trill 2 duration timer processing is immediately terminated. On the other hand, if it is within the duration, 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 toll direction flag U is “1”. When U = 0, that is, when the direction of the toll is in the down direction, the generated random number from the upper waveform is determined. On the other hand, when U = 1, that is, when the direction of the trill is the up direction, a waveform is selected according to the generated random number from the lower waveform (step S85).

  Next, sound generation by the waveform selected in step S84 or S85 is started (step S86), and the value of the toll direction flag U is inverted (U ← / U), and then this trill 2 continuation timer process is terminated.

  As described above, in the present embodiment, the musical sound played by the special playing method specific to the natural musical instrument is sampled, processed and stored in the memory such as the hard disk, and the natural musical instrument specific based on the stored musical sound data. Since the rendition style is simulated, timbre changes by various rendition styles specific to the natural musical instrument can be faithfully reproduced.

  In this embodiment, for example, waveform data for each performance method such as glissando waveform data and tremolo waveform data is prepared for each note. However, in a normal waveform memory sound source, it is easy to use an F number or the like. Since the pitch can be shifted, one waveform data may be prepared for each of a plurality of consecutive notes, and may be used by shifting the pitch according to each note. In that case, the capacity of the waveform memory can be reduced.

  Further, in the present embodiment, as a trill raw waveform data, a waveform by a pulling-off or hammering-on performance method is recorded. However, the present invention is not limited to this, for example, a finger of a fret, a trill by a pitch bend performance method, etc. May be a performance waveform.

  In this embodiment, the performance method designation and the performance information reproduction are individually performed. However, the present invention is not limited to this, and real-time performance or automatic performance reproduction is performed while performing the performance method designation in real time with the manual performance specification designation switch. May be performed.

  Furthermore, in the present embodiment, a waveform memory sound source has been described as an example of a sound source. However, the present invention is not limited to this, and the present invention can also be applied to other types of sound sources. In that case, instead of preparing a plurality of waveforms corresponding to a plurality of performance styles, only the types corresponding to the performance styles for which timbre parameters can be set are prepared, and in the same manner as the present invention, a sound generation control program suitable for each performance style is used. What is necessary is just to control.

  It should be noted that related information, operation programs, and the like for realizing the musical tone generation device of the present embodiment are stored in a storage device such as the hard disk, and the CPU 3 reads these into the RAM 5 and uses them. If data recorded on a portable storage medium such as a CD-ROM, floppy disk, or magneto-optical disk can be transferred to a storage device such as a hard disk, additional information (such as installation) and related information can be added. This is convenient for updating (version upgrade, etc.). Of course, data may be directly transferred from the portable recording medium to the RAM 5.

  Furthermore, when the musical tone generation device of the present embodiment is configured to include a communication interface, the related information and operation on a storage device such as a hard disk is not transmitted via this communication interface, but via a portable recording medium. You may make it download a program etc. from the communication network side. Hereinafter, examples of downloading related information, operation programs, and the like from the network side will be described.

  The communication interface is connected to a communication network such as a LAN (local area network), the Internet, or a telephone line, and is connected to a server computer via the communication network. The musical tone generation apparatus according to the present embodiment as a client, when related information or an operation program or the like is not stored in a storage device (hard disk or the like) included in the own apparatus, to the server computer via the communication interface and the communication network, A command for requesting related information or an operation program is transmitted. Upon receiving this command, the server computer distributes the requested relationship information, operation program, etc. to this apparatus via the communication network. The device receives the distributed relationship information, operation program, and the like via the communication interface and stores them in the storage device, thereby completing the download.

  Further, the present apparatus may be realized by a commercially available personal computer or the like in which the related information, operation program, or the like is installed. Of course, also in this case, as the distribution method of the data such as the relation information and the operation program, a method of storing in advance in a nonvolatile memory such as the ROM 4, a method of storing and distributing in a portable recording medium, and A method of distributing via a communication interface is conceivable.
