May fill in five, description of the invention (1) This invention is about high versatility Music tone waveform generation method. At present, there are a variety of practical electronic musical instruments, and there are also many types of electronic musical instruments used in the sound source part (tone generating device). Some of these electronic musical instruments use common sound source parts, but general electronic musical instruments use different sound source parts according to different models. Therefore, according to the different models of electronic musical instruments, a variety of different structures or data formats are used. However, this situation is very inconvenient. Therefore, in order to make the form or timbre of performance information among various electronic musical instruments have a certain degree of interchangeability, the GM (General MIDI) specification is set. For example, the GM specification stipulates the arrangement order of the tone colors corresponding to the tone number, and at the same time, even if a tone number that does not correspond to this model is specified, a similar tone can be selected. For example, performance information / timbral information created by a specific model, if this information is directly reproduced by other models, it is often impossible to successfully reproduce. The reason is that the hardware structure of the sound source part of different models is different. The contents are listed and explained as follows. Du Printing by employees of the Central Ministry of Economic Affairs of the Ministry of Economic Affairs (a) First, the conventional musical tone generation methods used in the audio source department are P CM method, FM method, physical model method, etc., and these musical tone generation principles are all different. . (b) At the same time, some sound sources are equipped with timbre filters, reverberation circuits, and various sound effect circuits. Therefore, it is difficult to produce the same musical tone signal without the sound source part. (c) At the same time, the types and number of parameters used by various sound source sections are different. "When using the same parameters, some of the parameters have a limited range of change, and some parameters do not operate at all. This paper scale is applicable to the Chinese National Falcon (CNS) Α4 specification (210Χ297 公 4) A7 300 ^^ 3 B7 5. Description of the invention (2) (d) The same parameters are also due to the hardware architecture of each model. different. For example, the same digital filter, but if the method or spatial degree is different, the effect of the cutoff frequency will also be different. (e) At the same time, the program for controlling the CPU of the sound source part also differs according to the model. The method of pronunciation distribution, the number of pronunciation series of a timbre, and the control time limit are different. As mentioned above, in traditional electronic musical instruments, the restrictions imposed by hardware or software architecture are many, lacking universality and interchangeability. The present invention has been completed in view of the above-mentioned facts, and its first object is to provide a musical tone waveform generation method capable of reproducing performance information in an electronic musical instrument in a state very close to other electronic musical instruments. The second object of the invention is to provide a method for generating a tone waveform using a computing device to generate tone with characteristics equivalent to those of most models. The third purpose is to provide a musical tone waveform generation method that can convert performance information created by assuming a specific model into highly versatile performance information. The fourth objective is to provide a method that can exceed the limitations of the model and assume specific The performance information created by the model can be edited to generate a colorful sound waveform. The fifth purpose is to provide a musical tone waveform generation method capable of performing highly accurate data conversion in order to faithfully reproduce performance information created on the assumption of a specific model with other models. In order to solve the above-mentioned problems, the feature of the structure described in item 1 of the scope of the patent application is that the method contains an instruction to simulate the electronic musical instrument device.

Printed by the Employee Consumer Cooperative of the Central Standard Falcon Bureau of the Ministry of Economic Affairs In the figure, the first layer is a physical layer composed of hardware such as CP U 9. The 2nd to 6th levels are logical layers made up of software that enables CP U 9 and other operations. The second layer is composed of the signal processing module 20, which is composed of subprogram groups that perform basic signal processing such as addition, subtraction, multiplication and division, bit shift, and delay. The third layer is composed of most sound source modules that use this signal processing module to generate musical data by various principles. Here, the content of the sound module will be explained first. At present, there are various conventional sound sources that synthesize musical data according to various principles, such as the following three types. First of all, the so-called "P CM sound source" is a copy of the paper that records the music waveform of the billion in advance in the memory of the billion. It uses the Chinese National Moumou (CNS) Α4 specification (210Χ 297 mm) 11 A7 __ B7 V. Invention Description (9) Sample data, read this sample data and convert it into an analog signal to output musical signal. It is called "FM sound source", and it has multiple operators (oscillator) 'use one of the operators to FM modulate the signal of the other operator' or synthesize the output signals of the majority of operators to each other. Wait for processing to form a musical signal (analog signal). The so-called "physical model sound source" is to imitate the behavior of various musical instruments to generate digital musical data and then convert it into musical signals (analog signals) * Furthermore, in addition to the above, there is a high-frequency wave synthesis method, Various musical methods such as composition method (Formant) synthesis method, ring modulation method, etc. This embodiment is equipped with sound source modules 31 to 33 (basic arithmetic) that can generate musical data according to these basic principles. First, the PCM sound source module 31 implements the basic action of a P CM sound source with a filter ( For the actions of various circuit blocks of the sound source), their individual processing is called the signal processing module 20 of the second layer to be executed.

At the same time, the physical model sound source module 33 realizes the basic actions of the physical model sound source of a certain wind instrument. Furthermore, the calculation method of the physical model sound source differs depending on the instrument (imaginary instrument) to be imitated. Therefore, sometimes a physical model sound source to be imitated is equipped with a plurality of physical model sound source modules 33. The basic principles of generating musical tone signals are as described above. However, even if the basic principles are the same, the actual algorithm used depends on the sound source L S I used in the model to be imitated. There are subtle differences.

At the same time, for the internal processing of the sound source LSI, the corresponding pseudo sound source 4 1 ~ 4 5 'is called out to imitate the sound source Or the entire synthesizer. In addition, for some audio sources, most audio source LSIs are sometimes used. Of course, most of the pseudo audio sources should be called out. 4 1 ~ 4 5 ° Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy Page) Various application software such as sequencer, games, arranger software 6 1 ~ 65 are provided on the 6th floor.

The sound source parameters enlarged in this figure are examples when the sound source of the electronic musical instrument to be imitated is P CM sound source. These parameters include waveform designation data that specifies one of the above waveform data. The specified data of this waveform is different in each range.

Description of invention (15) Enter the buffer 1 3 0 to determine whether to input new MIDI data from the MIDI interface 7. If it is not input, it is determined as "Ν 0", and the process proceeds to step S 4. When the process proceeds to step S 4, it is determined whether a SW (Switch) event has occurred. The so-called SW event refers to the window 2 0 ○ Mouse events within the keyboard, and keyboard events when window 2 0 is dynamic, etc. When there is no SW event, the process proceeds to step SP 6. At step SP6, it is determined whether a certain flag RUN is. Flag RUN It is the flag indicating whether the automatic calculation based on the performance information in the hard disk 3 is in progress. Therefore, it is judged as "NO", and the process proceeds to step SP10. At step SP10, the sound source processing subroutine shown in Figure 8 is called. However, if no data is written in the sound source temporary storage unit 140 , The subroutine of the sound source processing is not substantially processed. Furthermore, the content of the subroutine will be described later. Secondly, when the processing advances to step SP11, various other processes are performed. Step SP 2 to S pp 1 1 are repeated later Processing (hereinafter referred to as the main ring). B-3 Processing of MIDI events When event data is received at the MIDI interface 7, an insertion is generated to the CPU 9, and MI DI reception shown in FIG. 5 (b) is started Insert the program. In the figure, when the program is started, the process proceeds to step SP 2 1, and the received data is taken into a certain area of RAMI 1 from the MI DI interface 7. The paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) — -18-<please read the notes on the back before filling in this page)-S00dd3 A7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs _______B7 V. Invention description (i6) When the process is in progress When step SP 2 2 is reached, the slave timer 8 Read the moment information. The above-mentioned reception data and time information are regarded as event data and are written to the end of the input buffer 1 3 0. The "event data number" before the input buffer 1 3 0 is incremented by "1". After finishing the above steps, the processing returns to the sequence before insertion. After such processing is performed, in the main loop, when the processing proceeds to step s P 2 ', it is judged as "YES" here, and the processing proceeds to step SP3. In step SP3 ', based on the received data, the note code, note ON, and other data required to generate musical tones are written into the sound source register. The following will refer to FIG. 7 again to explain in detail the processing situation when the received data is a note. In this figure (a), when the processing advances to SP61, the variable NN stores the note code, and the variable VEL stores the velocity and timbre number. It is stored in the variable tn (〃 is the part number corresponding to the tone "1" ~ "16"). When the processing advances to SP62, the processing related to the ON of the note of the currently selected sound source driver DP (a) is executed (subroutine of layer 5). Specifically, for example, the subroutine shown in (b) of the figure is called. In the figure (b), when the process proceeds to step SP71, the register in the space of the sound source register section 140 will be assigned to the note 〇 N event. The sound source to be imitated is, for example, a type in which two series of sound sources emit one tone, and two sound source registers will be allocated. When the processing advances to step SP72, the sound source parameter PDn (v n f part number) is processed corresponding to the symbol code or speed. (Please read the precautions on the back before filling out this page) This paper scale is applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) 19-Μ Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs ) The following is a brief description of its contents. When the sound height of the instrument changes, not only the tone, but also the tone will change slightly, and the speed will also change it (for example, when you play the piano keys hard, the tone will not be the same as when you flick). Therefore, the conventional sound source corresponds to the phonetic symbol code or speed to make subtle changes to the sound source parameters. This embodiment imitates these sound sources', so the sound source parameters are processed by the same calculation method as the target sound source. Next, when the processing advances to step SP 73, the processed sound source parameters and the moment when the note is turned on are written into the previously assigned sound source register. Furthermore, it is one of the characteristics of this embodiment to write the moment when the note is ON to the sound source register, which is not the case with the traditional electronic musical instrument. The reason for this treatment will be described later. When the processing advances to step s P 74, the note ON is written to the previously allocated sound source register. When the above process ends, the process returns to the main loop via the note ON event processing subroutine. Furthermore, when events such as note F F (Note OFF), pitch bend, etc. occur, the same processing as the sound source to be imitated is also performed. Various data are written in the assigned sound source register. But no matter what event, this embodiment writes the "time of occurrence" into the sound source register. This is different from the actual (to be imitated) sound source. A B — 4 sound source processing ① The principle of sound source processing is this, when the sound source is temporarily The status of some data written in the memory section 1 4 0 (in other words, the state where a certain sound source register is assigned to certain pronunciations) This paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210 to 297 mm " 1 ~ — '' -20-----: -------- installed ------ one order ----- II (please read the precautions on the back first and fill in {Ϊ5 Page) A7 _ B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of the invention (is) 'Processing advances to SP 1 0', various substantive processes are performed in the sound source processing subroutine. The specifics of these processes Before the content, the operation principle of this embodiment will be described with reference to FIG. 9. First, in order to generate musical sound data based on the data written into the sound source register 1 40, various waveform calculation processes are required. However, if an event occurs, It is sometimes inappropriate to carry out the above treatment. That is, if it occurs during the treatment For other events, the majority of events must be processed in parallel. In this state, the calculation processing time will have a difference in length, which may have an adverse effect on the music. Therefore, this embodiment makes the delay caused by the calculation processing time uniform In order to prevent the adverse effects caused by the difference in the length of the calculation processing time. Therefore, the waveform calculation processing is processed intensively every TP. That is, in the figure (b), it is from the time t 1, t 2, t 4 and The waveform calculation process starts from t 5. The time T c required for the waveform calculation process varies depending on the time limit, but its maximum value is set to T CMAX. As described above, the regeneration unit 4 suitably generates DMA insertion into the CPU 9. Read out the RAMI 1 The music data is converted into a music signal and output. This read operation is performed according to a certain pitch.

Furthermore, the delay time TD will change according to how to set the above-mentioned fixed time TP, shorten the fixed time τP to make the delay time 1) around "0.01 seconds", then connect the instrument to the M IDI interface 7 for manual performance, There will be no sudden feelings. However, as previously explained, in this embodiment, it is necessary to write the processed sound source parameters and the time at which the note is generated into the sound source register. This is for the reason that the above sound source processing can be performed normally. That is, in this embodiment, in order to start the pronunciation after the delay time T D has elapsed from the time of occurrence of the event, it is necessary to obtain the time of occurrence of the event first. In other words, the sound source register of this embodiment is not only to simulate the operation of the sound source register of the sound source L S I to be imitated, but to perform the independent operation of this embodiment in the point of remembering the time information. ②Specific processing content The sound source processing corresponds to the sound source L S I to be imitated, and the sub-program of the fourth layer is called and executed. The specific example is explained below with reference to FIG. 8. In the figure, when the processing advances to step S 81, the contents of the sound source temporary memory section 140 are searched. Secondly, when the processing advances to step S 8 2 ', based on this search result, it is determined whether new data is written in any sound source register. If it is determined as "Y E S", the process proceeds to step S P 8 3 'to call the pseudo sound source SP (b). The quasi sound source SP (b) converts the data written in the sound source register section 140 into data for the sound source module control, and writes the result into a certain area of RAMI 1. When the process proceeds to step SP84, the sound source module MP (c) is called.

Description of invention (? 〇) Μ P (c) is divided into sound sources according to function Submodule μ P (c)-1 ~ 3, in step SP84, the sound source submodule MP (c) -1 is called. The sound source sub-module Μ P (c)-1 will prepare various parameters required for operation according to the converted data, in preparation for the next waveform operation processing (refer to Figure 9 (b)). That is, the newly written data is event data such as note ON, note 0 F F ’tone change, compression, etc. Therefore, the content of waveform calculation processing corresponding to these is specified here. The prescribed operation content is, for example, tone change only changes the tone, and compression only compresses the volume. In this way, the action of the sound source sub-module MP (c)-1 in imitating the various circuit blocks in the source L S I that should be imitated belongs to the third layer above. In addition, the processing of the pseudo sound source S P (b) and the processing of the sound source sub-module MP (c) — 1 are performed only on the pronunciation channel corresponding to the written sound source register. Next, in steps SP85 and 86, it is determined that the current time is the time limit for starting the waveform calculation process (time 1; 1, t 2, t 4 or t 5 in Figure 9). If the judgment is "N 0", the process returns to the main ring. Then, after the time reaches the above time limit, when the process proceeds to step SP86 again, it is judged as "YES", and steps SP87 to 8 9 are executed. First in step SP87, the sound source sub-module MP (c) -2 is called. The sound source sub-module Μ P (c) — 2 is prepared for waveform calculation processing according to the content previously specified in step SP 8 4. That is, various materials are displayed on the time axis. Then, when the processing advances to S Ρ 8 8, the sound source sub-module MP (c) _3 is called, and the actual paper size is calculated according to the Chinese National Standard (CNS) Α4 specification (210X29?

Description of the invention (21) Musical data. The processing of the above sound source sub-modules MP (c) — 2 and MP (c) _3 produces a musical sound with a position above quasi. That is, these processes are performed on all channels in the utterance, and calculation is performed for each channel to form the musical tone data of the above-mentioned fixed time TP minutes. The musical tone data of the formed channels are accumulated with each other in the sound source sub-module MP (c) -3, and the cumulative result completes the above-mentioned musical tone data for a certain time TP. When the processing advances to SP8, the reproduction of the calculated music data is reserved. That is, the reproduction unit 4 is set to make a reservation, and when the reproduction of the music data currently being reproduced is completed and the time to be reproduced is reached, the calculated waveform data is continuously reproduced. After finishing the above processing, the processing returns to the main ring. Therefore, the pronunciation corresponding to each event is executed after each delay time TD. B — 5 Handling of SW events Next, the handling of SW events due to the keyboard or mouse of the input device 1 will be explained. When the process proceeds to step SP 4 after the occurrence of the SW event, the process proceeds to step SP 5 to execute the process corresponding to the SW event. Detailed explanations are given below for different occasions. ① "File" button 2 0 1 When the "File" button 2 0 1 is tapped by the mouse in the window 2 0 0, the file selection window (not shown) is displayed on the display 2 overlapping the window 2 0 0.

When the user moves the mouse cursor 2 0 4 to any When a file name is tapped twice, the file will be in the "assigned" state. Then execute the file regeneration indication event processing program shown in Figure 6 (a). In the figure, when the process advances to step SP 3 At 1, it is ready to read out the specified file. Then 'when the process advances to step SP 32, the sound source is prepared according to the file header 101, the sound source parameter part 102 and the waveform data part 103'. The detailed description is as follows with reference to the figure (b). In the figure (b), when the process proceeds to step SP41, the "form of sound source" specified in the letterhead 101 is stored in the variable TGT. Then, the process proceeds By step SP 42, the variable TGT The content is parsed to take this specific sound source form. And in step SP42, the variables a, b, and c are determined according to the specific sound source form. Here, the variable a is the number of the sound source driver, and the variable b is the number of the quasi sound source It is the number of the sound source module. Then, when the process advances to step SP 4 3, the sound source driver DP (a) designated by the variable a is prepared. That is, the sound source driver DP (a) is read out from the hard disk 3 and stored in RAMI 1. Similarly, in steps SP44 and 45, the pseudo-sound source SP (b) and the sound source module MP (c) specified by the variables b and c are read from the hard disk 3. Then when the process proceeds to step SP 46, Then, according to the sound source parameters 1 〇2 of the specified file, prepare the sound source parameters (plural) on RAMI 1.

Second When the processing advances to step SP 47, the waveform data specified by the waveform data section 1 0 3 is expanded on the waveform data section 1 2 0. After finishing the above processing, the processing returns to the call source program (here It is the file reproduction instruction event subroutine). Then, in the file reproduction instruction event processing subroutine, when the processing advances to step SP 3 3, various preparations required for the automatic performance are performed. For example, read the first certain part of sequence data 104 in advance. After performing the processing in Figure 6 (a) and (b) in this way, the sound source driver, pseudo sound source, sound source module, etc. previously specified in the system setting will be based on the newly read performance information letterhead 1 〇1 ~ waveform Information 1 0 3 rewritten.

Description of the invention (24) In the tone selection table section 3 Ο 2, a list of selectable tones is listed, and the currently selected tones are displayed in reverse. The illustrated example selects "3 Electric Grand Piano" for part "1". In addition, the number added to each tone name is called the tone number. At this time, if you hit the part that displays the name of another tone, the part of the other tone will be reversed, and the original part will return to the normal display situation (this state is called "temporary selection") ° To change the part other than "1" When playing a timbre, tap the desired part number (“1” to “16”) in the corresponding index part 301 with the mouse, and the timbre selection table part 3 0 2 of the selected part can be displayed in the timbre selection window 3 0 0. In this way, if the cancel button 3 0 4 is tapped after proper selection of the tone, the interior of the temporary selection will be cancelled. On the other hand, if the OK button 3 0 3 is tapped with a mouse, the processing shown in Fig. 6 (C) is executed for each part. That is, the tone number tn (" system "1" ~ "16") of each part is changed to the tone number temporarily selected. Corresponding to the newly selected tone number t η, the sound source parameter section 110 and the waveform data section 120 are updated. After finishing the above processing, the processing returns to the main ring. In the future, the formation of music data will be performed according to the newly selected sound source parameters. ③Start event processing When you hit the regeneration button 2 0 3 with the mouse on the window 2 0 0, after the flag RUN is set to " ^ 1〃, the process returns to the main ring.

Description of invention (25) Proceed to step SP7. Here, it is judged whether or not the time of the next event within the sequence data 1 0 4 where performance information is generated has been reached. But for the events before the sequence data 104, the constant judgment is "Y E S". When the processing advances to step SP 8, event processing of the preceding event is performed. Furthermore, the content of this event processing is the same as the step S P 3 (processing of the input M I D I signal) previously described. For example, when the preceding event is a note ON, the processing shown in (a) and (b) of Figure 7 is performed. Next, when the process proceeds to step SP9, the time limit for the next event to occur is determined based on the period after the previous event (duration). The processing returns to the main ring. Thereafter, whenever step SP7 processing is performed in the main loop, it is determined whether the present time has reached the previously set time limit. When the current time has reached the above time limit, the process proceeds to step SP8, and event processing of the time limit is performed. ④Stop / Pause / Fast Forward / Fast Rewind event processing: Use mouse to hit the pause button 2 0 5 or stop button 206 on the window 2 0 0 'After the flag RUN is set to ♦ 〇〃, processing returns to the main ring. Therefore, there will be no processing from steps SP 7 to SP 9 in the future, so the automatic performance based on the performance information in the system is stopped, and only the performance based on the external MIDI data is performed. At the same time, if you tap the fast forward button 2 0 8 with your mouse, you will quickly skip the sequential data. When the rewind button 2 0 7 is tapped, the sequence data 1 0 4 is skipped in the opposite direction. 1111 counties ((:) ^) 44 tests (21 () \ 297 public envy) used in this paper ruler '~ -28----- Γ-,-Τ1 养 ------- Order ------- \ (please read the precautions on the back before filling in this page) Employee Consumer Cooperation of the Central Bureau of Standards of the Ministry of Economic Affairs Du Print 3009ij3 at B7 5. Description of the invention (26) Effect of the C embodiment ① This The performance information of the embodiment includes not only sequence data 1 ο 4, but also letterheads 1 〇1 of a specific sound source, etc., a sound source parameter 102 specifying a timbre, etc., and a waveform data section 103 specifying a musical tone waveform. This can accurately imitate various sound sources operating on various principles. ② Since the "time of occurrence" of each event is written in the sound source register in this embodiment, the delay of the calculation processing time can be made uniform by this. D Modification Examples The invention is not limited As in the above embodiment, for example, the following variations are possible: ① The sound source driver, pseudo sound source, sound source module, etc. of the above embodiment are read from the hard disk 3 into R Α Μ 1 1 when specified by performance information, etc. However, the files that are used more frequently can be read into RAMI 1 in advance regardless of whether they are designated or not. This can reduce the extra time required to read files such as the audio source drive from the hard disk 3 after specifying the information file. ② The algorithm of the audio source module 3 1 ~ 3 3 can be changed according to the category of the pseudo audio source 4 1 ～ 4 5 For example, the arithmetic number of the FM sound source module 3 2 is “6”, but if the arithmetic number of the sound source LSI to be imitated is “4”, you can also change the arithmetic number of the FM sound source module 3 2 Reduced to "4." Similarly, if the sound source LSI emulated by the PCM sound source module 31 does not have a filter processing function, the filter processing function can also be deleted from the sound source module 31. ③ The above-mentioned embodiment is at step SP 8 3 Call out the sound-like sound source SP (This paper standard applies to the Chinese National Standard (CNS) A4 specification (210X297mm)
