Description of the invention (1) [Technical field to which the invention belongs] The present invention belongs to the technical field of generating musical sound data, and in particular relates to a device that can be applied to a general-purpose arithmetic processing device such as a CPU to perform musical sound generating processing and method. [Known Techniques] In today's electronic musical instruments, micro-processing is widely used to perform tone generation processing (including processing added to tone generated by tone generation processing). As the above-mentioned micro-processing program, it is generally designed to use circuits corresponding to the sound generation method (such as waveform memory method or FM synthesis method, etc.) to form dedicated hardware (such as sound source LSI or DSP (liquid crystal signal program), etc.). Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page). However, in recent years, with the improvement of the computing power of the CPU, it has been installed in a CPU installed in a general-purpose computer or a dedicated music generator , The device that performs the tone generation process starts to ask the market. Here, the above-mentioned tone generating device or tone generating method is referred to as a CPU sound source or a software tone source. In contrast, a tone generating device or tone generating method that is formed using a conventional hardware is called a hardware tone source. [Problems to be Solved by the Invention] In the software sound source, the CPU is not only used for tone generation processing but also must perform other various processing in parallel. Therefore, when using a general-purpose computer to realize the software sound source, in order to ensure that the tone generation process is not affected by other processing effects, in addition to the multi-tasking 0S (operating system) (for example, this paper standard is applicable to the Chinese National Standard (CNS)) A4 specification (210X297 mm) · 4-Printed by Beigong Consumer Cooperative of Central Bureau of Standards, Ministry of Economic Affairs 312776 A7 ___B7_ V. Description of invention (2) Windows95 (Shangjie), etc. manufactured by MICRO must be able to produce music . However, 0S (for example, Windows 3.1 (Shangqi) manufactured by MICRO Co., Ltd.) that does not have complete multitasking functions is widely popularized. Therefore, there is an urgent need for tone generation processing on the above 0S. However, due to the influence of other processing, the above-mentioned 0S will cause delay in the process of tone generation processing, and as a result, there will be obstacles in vocalization. In view of the above-mentioned problems, the present invention provides a software sound source type music sound generation device and music sound generation method that does not cause a sound barrier when performing sound generation processing using 0S that does not have a fully multitasking function. [Method for Solving the Problem] The first musical tone generating device of the present invention includes a supply device for supplying performance information, and a starting device that can start the musical tone generating process of the performance-playing information multiple times within a predetermined time, and is performed by the starting device The tone generating device that activates the tone generating device, and the starting device only has an opportunity to actually activate the tone generating process, and has an adjustment that can perform the tone generating process performed by the tone generating device to generate a general predetermined sample within a predetermined time Adjusting device of digital music data. In addition, the first musical tone generating method of the present invention is a musical tone generating method that performs musical tone generating processing in a general-purpose arithmetic processing device based on supplied performance information, and a first step of starting the musical tone generating process a plurality of times within a predetermined time, And the opportunity to actually start only with the sound production process in the first step above, in order to produce a generally predetermined number of samples within the predetermined time, the paper standard of the China National Standard (CNS) A4 (210X297 mm) 5 _ 丨 丨 ------ ^ _Set ----- order ----- recognize the ball (please read the precautions on the back and then fill out this page) 312776 A7 ____B7_ V. Description of the invention (3) The second step of the adjustment of the musical tone generation processing is performed on the sound data, and the third step of the musical tone generation processing of the first step activation is performed according to the adjustment of the ankle of the second step. The software sound source generates music data of a predetermined number of samples in each predetermined time, which can simultaneously reproduce the music data of the predetermined number of samples. As mentioned above, the software sound source is generally such that the music generating process for generating the music data of the predetermined number of samples can be completely started only once in each predetermined time. However, an OS that does not have a fully multi-tasking function may not be able to start the tone generation process or delayed start within the time due to other processing. Therefore, the inability to complete the generation of the tone data within the predetermined time causes an obstacle to sound generation. In contrast to this, the first musical tone generating device and musical tone generating method are in the above-mentioned software sound source, and the opportunities for starting the musical tone generating process are set a plurality of times within the above-mentioned predetermined time. When starting, it is still possible to complete the generation of the musical data of the predetermined number of samples in the predetermined time by the opportunity of the start processing. It can be used to prevent the occurrence of dysphonia. Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) Furthermore, once the processing time of the non-activation increases, only the opportunity of actual activation processing will be used for all the processing of the distribution of tone generation The vocal channel cannot produce the above-mentioned predetermined number of musical data within the above-mentioned predetermined time. Therefore, in the above case, in the first tone generating device and tone generating method, by reducing the number of vocalization channels that generate tone data, the generation of vocalization data of the predetermined number of samples can be ensured. Secondly, the second tone generating device of the present invention has a supply device that adapts the performance capital paper standard to the Chinese National Standard (CNS) A4 specification (210X297 mm) -6-312776 A7 B7 V. Invention description (4) When the musical tone generating device of the performance information is allocated to an unused vocal channel, it is stored in the first register that controls the parameters of the process, and a new musical tone generated according to other musical performance information is allocated to the vocal channel in use. During processing, the second register that controls the parameters of the process can be stored, and before the time when the new tone generation process starts, select the first register, and select the second register after that time. Instead of the selection device of the first register, and the tone generating device that uses the register selected by the selection device to generate the tone data of the utterance channel is a special person. In addition, the second tone generation method of the present invention is a tone generation method that performs tone generation processing in a general-purpose arithmetic processing device based on supplied performance information, and is characterized by including distributing tone generation processing to unused In the vocalization channel, the parameters that control the processing can be stored in the first step of the first register, and the tone generation processing can be redistributed in the vocalization channel in use, and the parameters that control the processing can be stored in the first .1 The second step on the second register separately provided by the register and the time when the new tone generation process starts, select the first register and select the second register after that time To replace the third step of the aforementioned first register, and the fourth step of generating the musical tone data of the vocal channel using the register selected by the aforementioned third step. In the software sound source, when the other sound processing fails to start the tone generation processing, when the delay is started with f, the performance information is supplied to the female so that the time for starting the tone processing based on the performance information increases. Therefore, most of the vocalization channels for the distribution of musical tone generation and processing will contain the temporary paper size of the parameters that control the production and processing of glucosides.

Description of the Invention (5) In the state where the parameters are stored in the memory, the state where the tone generation process has not been started may occur. When the tone generation processing of newly supplied performance information is allocated to the utterance channels in use in the above state, the control of the new tone generation processing cannot be performed due to the long time until the tone generation processing of these utterance channels is completed The parameters are stored in the temporary memory (that is, new tone generation processing cannot be prepared in these utterance channels). In addition, even when the tone generation process is started, the new tone generation process of these uttered channels cannot be performed, which may cause a delay in the generation of tone data. In contrast, the second tone generating device and the tone generating method are such that, even when a new tone generating process is assigned to the currently used utterance channel, the current tone of the utterance channel using the first register can be ensured The generation process is performed, and new tone generation processes for these vocal channels can be prepared immediately in the second register. Therefore, it is possible to prevent the occurrence of delays in the sound data due to preparation for the sound generation processing. Secondly, the third tone generating device of the present invention is characterized by having a supply device that provides performance information; a plurality of output buffers respectively written with tone data: performing tone generating processing first, and one of the plurality of output buffers can be reserved A reservation device for reproducing part of the output buffer; generating musical tone data based on the aforementioned performance information, and writing the generated musical tone data into any of the remaining output buffers in the plurality of output buffers to reserve the musical tone reproduced by the output buffer Generation device: and, a playback device that performs reading of the output buffer according to the order of playback reservation.

The delay of the activation of the "sound source" will cause an obstacle to sound generation. Therefore, the cyanobacterium music system adopts the following measures to prevent the occurrence of sound disturbance. [Countermeasure 1] Activate "in each section" The internal interruption signal of the "Sound Source" has multiple opportunities to generate the above-mentioned predetermined number of samples (1 output buffer amount) of the music data of each of the music data in each start, thereby adjusting in these 1 sections Proceed to generate 1 output buffer of music data. Also, at any opportunity, the “sound source unit” cannot be activated due to the failure to generate an internal interrupt signal. As a result, the music data cannot be generated. Subsequent internal interrupt signals within the segment will generate the ungenerated tone data at the same time, thereby making it possible to adjust the tone data generated in these zones to ensure an output buffer amount. As mentioned above, in each zone The internal interrupt signal of the sound source part J is set to occur within a plurality of times. When the internal interrupt signal fails to occur for several times in this multiple opportunities, the opportunity to generate an internal interrupt signal in these sections can still be used to complete 1 The sound data of the output buffer S is generated, thereby preventing the occurrence of dysphonia. Figures 5 and 6 respectively show an example of this [Countermeasure 1]. Examples of these are within a 100-ms length section, with each A time of 10 milliseconds (therefore-a total of 10 times within the zone) an internal interrupt signal that activates the "Sound Source" occurs. This paper standard is applicable to the Chinese National Standard (CNS) A4 specification (2! 〇 > < 297mm I ^-; f I #-(please read the precautions on the back before filling out this page) Order the A7 _____ B7 for consumer cooperation of the Central Standards Bureau of the Ministry of Economy V. Invention Instructions (13), In each start-up, it is possible to generate one-tenth of the tonal data of one output buffer of the tonal data. In addition, the example of FIG. 5 is such that all the musical tone data that has not been generated within the time when the internal interrupt signal does not occur are generated at the opportunity of the subsequent internal interrupt signal. That is, the second opportunity (with the 10th millisecond time in the figure) where the internal interrupt signal has not occurred is used for the third opportunity (with the 20th millisecond time in the figure) of the subsequent internal interrupt signal, and these opportunities The merger of glucoside data is completely generated (indicated by 2, 3 in the figure), and the 6th and 7th chances of no internal interruption signal are not generated. The 8th chance of subsequent internal interruption signal is used. (The 70th millisecond of the 囵) Generated together with the musical data of these opportunities (shown as 6 ~ 8 in the figure). On the other hand, the example of FIG. 6 is a case where musical data that is not generated in the opportunities where the internal interrupt signal does not occur are scattered and generated in a plurality of opportunities where the internal interrupt signal occurs subsequently. That is, the ungenerated music data in the 3rd and 3rd opportunities (10th and 20th milliseconds) of the internal interruption signal are not used, and the 4th and 5th opportunities (the first in 30. Printed and printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) 40 milliseconds), and can be distributed together with the music data of these opportunities (the 2, 3 and 4, 5). However, in the last 10th opportunity (the 90th millisecond time in the figure), in order to ensure the generation of 1 output of tone data in these sections, the 7th, 8th, and 9th chances that no signal has occurred (pictured) The 60th, 70th, and 80th millisecond times) of the ungenerated tone data are all generated. In Figure 6, although the ungenerated tone data is allowed to disperse the generated amount of tone sounds in a single start opportunity, and make it happen later The paper size of the internal interrupt letter applies to the Chinese National Standard (〇 邶) 84 specifications (210 father 297 mm) _16 _ Printed A7 B7 by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Generated, but not limited to this, it can disperse the ungenerated musical data in an appropriate amount of musical data (for example, the musical data generated by one starting opportunity, or the musical data generated by 1.5 times the starting opportunity, or 1 The second starting opportunity generates half of the music data), and it is generated in the subsequent opportunities. In addition, in another example, the tone data that is not generated in the opportunity where the internal interrupt signal does not occur is gradually generated so that the last opportunity in these sectors is reached (the 10th opportunity in FIGS. 5 and 6). In addition, when the chance of no internal interruption signal increases, the chance of the subsequent internal interruption signal will cause the tone data to be generated from all the utterance channels that cannot be completely processed by the distribution tone generation process. Therefore, in [Strategy 1], if the above-mentioned opportunities occur, the generation of tone data can be ensured by reducing the number of vocalization channels that generate tone data. However, the frequency of the number of vocalization channels that must generate musical data is the highest as shown in the example of FIG. 5, or as shown in the example of FIG. 6, or until the non-produced musical data is slowly generated so that the last chance in these sections is, An example lower than the garden 5 will be formed (however, from the early point of view of the generation of unproduced musical data, the example in Figure 5 is the most appropriate). [Countermeasure 2] As a sound source register for each utterance channel, a parameter that controls the processing of the distribution tone generating device when the utterance channel is not used can be set to cover the first sound source register (surface sound source register), and the use of such The second sound source register (internal sound source register) that stores the parameters that can control the new tone generation processing in the sound channel use. And this paper standard for the new tone generation process is applicable to the Chinese National Standard (CNS) A4 specification (210Χ297mm L 17---------- <-装 -----.— Order ------ ί, (please read the notes on the back before filling out this page) Beigong Consumer Cooperative, Central Standards Bureau, Ministry of Economic Affairs, printed 312776 A7 B7 V. Inventions Note (15) Up to the time, the surface sound source register is selected as the sound source register using these channels. After this time, the internal sound source register can be selected to replace the surface sound source register. As described above, even when a new tone generating place is allocated in the currently used vocal channel, the new tone generating process of the surface sound source register can be performed, and the new tone generating process of the vocal channel can be immediately processed Ready to be placed in the sound register of the masked sound source. It can prevent the delay in the preparation of musical sounds due to delays in the preparation of musical sounds. [Countermeasure 3] In the area where a plurality of output buffers are provided in the RAM 5, first "start the sound source section j," and reserve a part of the output buffer for reproduction in the "output buffer". Therefore, even if the "sound source" that should be activated in each zone cannot be activated in these segments due to the influence of other processing, the "sound source 1" can be activated until the reproduction processing of the output buffer of the reproduction reservation is completed. When the reproduction of the output buffer is reserved, the sound will not be interrupted during the reproduction of the musical sound. Therefore, it is possible to expand the tolerable range of the processing start time delay that does not cause the sound to be interrupted. Bit 7 is a diagram showing an example of this [Countermeasure 3]. In this example, the "sound source" is started first, and the reproduction of four output buffers is reserved in the "output device j." At the beginning of the segment F1, the reproduction process of the output buffer of the previous segment 1 is completed. The number of reservations becomes 3, but on the way to section F1, the reservation output buffer is reproduced due to the completion of the generation of 1 output buffer music data, and the number of reservations is increased to 4. Also, the paper size applies to section F1.

Description of invention (16) The number of reservations was reduced to 3 at the time of completion due to the reproduction processing of the next 1 output buffer, but the second output buffer was completed on the way to section F2 The generation and reproduction of music data and the reservation of its output buffer increase the number of reservations to 4. After that, due to the delay of the "sound source", the music data cannot be generated, so the number of reservations is reduced to 1 at the end of section F4. And read in the section F5 (in the figure, in order to make the relationship between the reproduction reservation and the readout more clear, in the middle of the section F2, a thick arrow indicates the occurrence of the reproduction reservation, and a diagonal line indicates the section F5) The last output buffer of the reproduction reservation (the output buffer of the reproduction reservation in the middle of the section F2), but in the middle of the section F5, due to the completion of the generation of 1 output buffer amount of music sound material and the reproduction reservation of its output buffer The number of appointments has increased to 2. Then, the number of reservations is increased or decreased in accordance with the completion of the reproduction process and the occurrence of the reproduction reservation. As mentioned above, even if the "sound source" that should be activated in each zone fails to be activated in these zones, it is only necessary to start the "sound source" reservation before the playback processing of the four output buffers of the reproduction reservation is advanced The reproduction of the output buffer can eliminate the delay of the tone reproduction. Furthermore, when the number of reservations is 4, when the next generation of music data with an output buffer amount is completed in the middle of a zone, the output buffer is reserved after waiting for the reproduction processing of these zones to be completed, thereby making the number of reservations possible No more than 4. The number of output buffers preset in the RAM 5 for the implementation of this [Countermeasure 3] is the number of output buffers for which the “sound source section” is first activated and reproduced, and the number of musical data written in the “sound source section”. Output buffer, and the amount of musical data generated by the "Sound Source" exceeds 1 output buffer.

Description of the invention (17) Total output buffers at the time of placement (6 in the example of Figure 7). Especially in the "sound source", when the amount of musical data generated exceeds 1 output buffer, it is only necessary to stop the generation, so that no output buffer is required (thus, the example of Fig. 7 requires only 5 is sufficient). [Countermeasure 4] When the reserved output buffer cannot be reproduced in the "output device" within the predetermined time, the generation of the musical tone data that should be completed is interrupted within that time, and the musical tone data from the beginning of the generation is restarted within that time. Generate action. In this way, when the reservation is not immediately reproduced and the music is temporarily disrupted, the stable sound generation operation can be restored immediately to minimize noise. For example, in the aforementioned [Countermeasure 3] Example 7, the playback reservation can be exercised in advance until all the playback processing of the output buffer of the output device j is completed. Output buffer for music data. However, when the "sound source" is greatly delayed due to the influence of other processing, the music data generated by the completion of writing the "sound source" can also occur in the interval where the reproduction processing of the output buffer that has made the reservation reservation is completed. Of the output buffer cannot reproduce the reservation (the number of reservations is 0). As mentioned above, it is only necessary to implement [Countermeasure 3] and [Countermeasure 4] in combination. When the number of reservations is 0, the generation of music data that should be completed can be interrupted within its time, and the output buffer can be performed again in the "output device" After the reproduction reservation, the music data from the start of generation within its time restarts its generation operation. Next, referring to Figure 8, the following description includes the computer audiobook paper scale that includes the implementation of the above measures. The Chinese National Standard (CNS) A4 specification (210X ^ 97mm) L 2〇- ~ ~ ---: ------- -------- 1T ------ ^ ^ (Please read the precautions on the back before filling in this page) A7 B7 312776 V. Description of the invention (18) The action example of the music system is as follows. FIG. 8 is a flowchart showing that the CPU 3 performs the main route. Initially, perform "Initial setting j (step S1)." Initial setting "is as shown in Figure 9. Initially, all the sound source registers for each vocal channel are cleared (as described in [Countermeasure 2], with internal sound source temporary storage and surface temporary Data), and data in the working area of RAM5 (in this working area, as described in [Countermeasure 3] contains a plurality of output buffer areas) (step S21). Next, load the waveform data recorded in the hard disk of the hard disk device 10 into the RAM 5 (step S23), and as described in [Countermeasure 3], first start the "sound source" to clear the number of data (in the This is the same as four in the example of FIG. 7) The reproduction of the output buffer is reserved in "Output Pack« "(step S24). Subsequently, the reproduction sample time from the DAC 12 is provided to the DMA controller 11, thereby starting the "output buffer" and the software time at which the interrupt signal inside the "sound source" is started (for example, refer to the CPU 3 to configure the hardware The timer has an internal interrupt signal) (step S25). The software timer is described in the above [Countermeasure 1], and the internal interrupt signal can be generated by multiple opportunities in each segment (this is the same as the example in FIG. 5, and it can be every 10 milliseconds in a 100-ms segment A total of 10 opportunities occur). In addition, the internal interrupt signal of the aforementioned software timer does not necessarily occur in each start opportunity (that is, every 10 milliseconds), or even when the start opportunity comes, when the CPU 3 is occupied by 0S processing or other software processing , Still cannot start the internal interrupt signal relative to the software source. The configuration of the start command generation device as described above is, for example, to set a purlin paper standard with the timer 2 to calculate a predetermined time (for example, 10 milliseconds) corresponding to each start opportunity, and apply the Chinese National Standard (CNS) A4 standard (210Χ297 21) (Please read the precautions on the back before filling out this page) 丨 Installed _,-ιτ · Printed by the Central Standards Bureau of the Ministry of Economic Affairs Beigong Consumer Cooperatives Printed by the Central Standards Bureau of the Ministry of Economy Printed A7 _____B7_ 5 2. Description of the invention (19) Note that in the state where the CPU 3 can perform the soft skull sound source, check the presence or absence of the mark. If an unprocessed purlin is set up so that an internal interrupt signal occurs, the mark can be eliminated. Therefore, within a predetermined time (for example, 10 milliseconds) corresponding to one startup opportunity, such as when the CPU 3 still has the margin to process the software audio source, an internal interrupt signal occurs once. However, between the predetermined time (for example, 10 milliseconds) corresponding to one start opportunity, if the CPU3 does not have the margin to process the software audio source, the mark detection will not be performed, so the internal interrupt signal will not occur, so that the predetermined time passes In the state of the second mark. That is, the internal interrupt signal corresponding to the previous Sassafras will not occur. Such an internal interruption signal is illustrated in Figures 5 and 6, and does not necessarily occur in each starting opportunity. And according to the above, it can be understood that even if the internal interrupt signal continues to occur in multiple individual startup opportunities, the time interval of its occurrence may not be the correct predetermined time (for example, 10 milliseconds), but may be appropriate around 10 milliseconds. change. That is, the micro-occurrence time of the internal interrupt signal is related to the processing state of the CPU 3 (when the timer flag is observed). . Revert to Figure 8-Once the initial settings are completed, a panel (not shown) showing the information of the corresponding processing progress or using the mouse to input various control data (Step S2) is displayed. In addition, first activate the "sound source" and reserve the output buffer reproduction of the "initial setting" (Figure 9) in the "output device". After the "output device S" is completed, the four output buffers that are reserved first After the reproduction process, the reproduction process of the output buffer of the subsequent reproduction reservation is performed by the "sound source unit". Therefore, once the MIDI information is supplied to reproduce the music, the length of the segment equivalent to increasing the number of output cushions that are reserved first (the example in FIG. 7 is the 4-segment quantity) length (delay this paper standard is applicable to the Chinese national standard ( CNS) A4 specification (210X297mm I 22----: ------------ (please read the precautions on the back before filling out this page) Order the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs Printed A7 ___B7__ V. Description of the invention (2〇)) Therefore, when the display provided by the MIDI information is displayed on the panel of the display 9, the display time can be staggered back by this section as appropriate. Follow step S2 The following step S3 can detect the occurrence of each of the following starting factors. Starting factor ①: Provides MIDI information from the “sequence program” (see Figure 2). Starting factor ②: The internal interruption of the “sound source” by the software timer Signal. Starting factor ③: Detect the processing request from the "output device". Starting factor ④: Detect other requirements (input event on the panel, or command input event on the keyboard 8 (except the main path termination command)). Starting factor ⑤: Detect the input event of the end command of the main path of the keyboard 8. Secondly, determine whether any of the above mentioned starting factors (step S4) occur. If it is NO, return to step S3 and repeat the processing of steps S3 and S4 So that any start occurs because of the stop. And if any start cause occurs, step S4 is YES, then proceed to step S5. Step S5 can determine what is the cause of the start. When the start factor ① occurs, MIDI information processing is performed (step S6) ), Perform (step S7) scheduled reception display on the panel (for example, display of MIDI information for supplying MIDI channels, etc.) and return to step S3 to perform the processing below step S3. In the MIDI processing performed at step S6 For example, including end-of-record event processing based on the start of recording, or start-of-record event processing based on the end of recording, etc. 圚 10 is a flow chart showing an example of processing of start-of-recording event.

Description of the invention (2!) It is to store the data indicating the recording start event occurrence time on the time axis indicating the input recording number, speed, component number of the input and recording MIDI channel, and the input time of MIDI information in the schedule In the temporary registers NN, VEL, P, and TM (step S31). Secondly, the utterance distribution process of the start of such recording is performed, and the channel number of the utterance channel of the distribution process is stored in the temporary register i (step S32). Then, read out the sound data of the selected timbre corresponding to the component number in the register p from RAM5, and convert the sound data corresponding to the record number and speed in the registers NN and VEL (see Figure 2) into the "sound source" Control parameters for control (including the frequency number FN of the specified pitch) (step S33). In addition, this control parameter and the data at the start of recording and the time of occurrence in the register TM are simultaneously stored in the sound source register of the channel number in the register i. The reservation to start recording at the time of occurrence (step S34). The data at the time of occurrence in the register TM is stored in the sound source register for the following reasons. There is a time difference (delay time for tone reproduction) of about 4 segments as described above between the time when the recording start event occurs and the time when the tone is reproduced based on the recording start event. The tone generation processing (“sound source processing 1” described later) is to generate the corresponding tone data at any time within the time difference range (ie, the processing delay allowed within the range). Therefore, if the tone generation processing performed at an arbitrary time different from the recording start event occurrence time cannot be known at the recording start event occurrence time, the corresponding musical tone data cannot be generated. In addition, in step S34, when using these vocal channels, such as [This paper standard is applicable to China National Standard (CNS) Α4 specification (210Χ297mm) · 24------------- ----. 玎 ------ ί I (Please read the precautions on the back before filling out this page) A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of invention (22) Countermeasure 2] It is to be noted that, in the sound source register for the vocal channel and the sound source register inside, the control parameters and the like are stored in the sound source register inside. In this way, the surface sound source register can be used to ensure the performance of the current tone generation processing of the utterance channels, and the new tone generation process of the utterance channels can be immediately prepared in the inside sound source register. In addition, when the above-mentioned surface-mounted sound source register is stored, it is also possible to perform power-off within the time corresponding to the occurrence time in the register TM within the reserved area in the surface sound source register (a process that sharply reduces the volume seal) ) Appointment. Step S35 subsequent to step S34 is to determine the calculation order between the respective utterance channels when performing the utterance assignment process based on the order of the utterance channels whose recording start time is delayed, and perform the tone generation calculation. (That is, the vocalization channel corresponding to the start of the subsequent performance record can be treated preferentially when the tone is produced). And return to the previous step. FIG. 11 is a flowchart showing an example of the event of recording termination event. Initially, the recording number, the sound selected by the component of the MIDI channel that received the input recording is terminated, and the raw materials indicating the time when the recording termination event occurred on the time axis indicating the input time of the MIDI information are stored in the predetermined registers NN, t , Within TM (step S41). Then, it searches for the utterance channel of the tone in the allocation register t, and stores the utterance channel number in the register i (step S42). In addition, in the surface sound source register for the sound channel of the channel number in the register i and the inside sound source register, the corresponding temporary storage is performed in the reservation area in the sound source register corresponding to the tone in the register t Appointment for the recording of the time of occurrence of the time in the device TM (step S43) ◊ and return to the previous step.

And it returns to step S3, and repeats the process after step S3. "Sound source processing 1" forms a part of the "sound source part". This "sound source processing 1", as shown in FIG. 12, initially subtracts the tones based on the MID 丨 information from the input time of the MIDI information on the time axis at the current time GT on the time axis indicating the input time of the MIDI information The final input time ST setting (step S51) at the completion of the generation process is the generation set SR (the target number of samples representing the musical sound data generated at the start this time). That is, in step S51, as shown in the example of FIG. 5 in [Action 1], when an internal interrupt signal cannot be generated in any opportunity and the "sound source unit" cannot be activated, music data that has not been generated in the opportunity may be generated. Take advantage of all the opportunities in the subsequent occurrence of internal interrupt signals. In this way, even if the internal interrupt signal fails to occur several times in one zone, the generation of the tone of the 1 output buffer in these zones can be completed only by the opportunity of the internal interrupt signal, thus preventing the audible obstacles What happened. Refer to FIG. 5 to specifically indicate that the generated amount SR is that the first chance is 10 milliseconds, but when the second chance fails to generate an internal interrupt signal, the third chance is 20 milliseconds. Besides, as shown in Fig. 5, multiple opportunities without internal interruption signal can be dispersed or generated slowly until the last opportunity in these sectors, as described in [Countermeasure 1]. Next, set the tone generation area with SR at the first output buffer out of the output buffers other than the "Initial setting" (圚 9) output buffer other than the reserved output buffer (step S52) ° The Chinese national standard (CNS) A4 specification (210X297mm) is applicable to the paper size. (Please read the precautions on the back before filling out this page)-Binding · Order A7 printed by Beigong Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs ___B7 Fifth, the description of the invention (24) determines the number of music audio channels to generate music data (step S53). The decision to make this number of vocalization channels is as follows. First, the calculation time required to generate the musical data of the generated amount SR according to one vocal channel, and the current calculable time EJ (subtract the actual time of the internal interrupt signal from the scheduled time SJ of the second internal interrupt signal occurs) Calculate time KJ), calculate the number of vocalization channels in the EJ at that time may produce music data that generates SR. Moreover, when the calculated number of vocalization channels that can be generated is greater than the number of vocalization channels for which vocalization is allocated in the recording start event processing (Figure 10), the number of vocalization channels for which these vocalization allocations are made can be determined as the number of vocalization channels that generate musical tone data. On the other hand, if the calculated number of vocalization channels that can be generated is less than the number of vocalization channels for utterance allocation, the number of vocalization channels that can be generated can be determined as the number of vocalization channels that generate musical tone data (ie, as in [Countermeasure 1] Explain that by reducing the number of vocalization channels that generate data, you can ensure the production of 1 output of glucoside data in 1 section). The step S54 after step S53 is to store the calculation sequence (determined by the recording start event processing step S35) in the channel number i of the first-ranked sound channel, and the time ST is indicated by the starting point sp. Then, referring to the reservation area of the surface sound source register for the sound channel of the channel number in the register i, from the start point sp to the time GT, the initial reservation (pitch section reservation, recording termination reservation) is detected , Appointment for power failure, etc.) (step S55). Then, it is judged whether a reservation is detected (step S56). If it is YES, the tone generation processing for the reserved time is performed for the utterance channels, and the starting point is advanced to the reserved time (step S57). This tone generation process is as described above. The waveform is read from RAM5 at a pitch stored in the control parameters of the sound source register. The basic paper scale on the waveform data is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm X27 ----.------ < -install-- (please read the precautions on the back before filling in this page) Order A7 312776 _B7_ V.

Printed and printed by the Ministry of Economic Affairs and Consumers Cooperative Staff Consumer Cooperatives. The Puma S5 8 and the Pega S5 8 are those who store the contents of these appointments in these glycoside registers and make the appointments. Therefore, once the recording termination reservation is detected, the recording termination is written into the surface sound source registers of the vocal channels, and the release of the sound-set seal is started. In addition, when the power-off reservation is detected, after power-off is completed (that is, after the volume wave seal level is formed below a certain value), as shown in [Action 2], select the internal sound source register instead of the surface temporary storage As the sound source register used by these sound channels (especially after first replacing the surface sound source register with the internal sound source register, you can also turn off the surface sound source register). Furthermore, as described in step S34 of FIG. 10, when the data of the control parameters, the start of recording, and the time of the start of recording in the register TM are stored in the internal sound source register, the reservation area of the surface sound source register Make a reservation within the time period corresponding to the moment of occurrence in the register TM. Therefore, in the tone generation process, once the time corresponding to the utterance time in this register TM comes, after the power is turned off, the sound source register inside is used instead of the surface sound source register to start the tone generation process. Step S58 Once completed, return to step S55 and repeat the steps below step S55. On the other hand, when it is judged as N0 in step S56 (or when it is initially judged as YES and then judged as NO through steps S57 and S58), all sound generation processing from the starting point sp to the time GT is performed on these utterance channels This paper scale is applicable to China National Standard (CNS) A4 specification (210X297mm) L 28-Printed by the Ministry of Economic Affairs Central Standards Bureau Negative Consumer Cooperatives 312776 A7 B7 V. Description of invention (26) (Step S59). For these utterance channels, the generation of tone data in the tone generation area after the generation amount SR can be completed. Secondly, at step ankle S53, it is judged whether all tone generation processing is completed for the determined number of utterance channels (step S60). If NO At the time, store the number of the vocal channel with the next highest order in the register i, and set the starting point sp to the time ST (step S61). And return to step S5 5 Repeat step Mule S55 below On the other hand, when it is determined to be YES in step S60 (or when it is initially determined to be NO and then determined to be YES by repeating step S55 and the following step mules), the musical tone generation process is advanced to step S62. This can generate a sound When the number of sound channels is less than the number of vocalization channels for which the vocalization interruption process is performed, the form of the tone generation processing of delaying the number of vocalization channels in the calculation sequence can be omitted, and the number of channels that simultaneously sound can be reduced. The data (or those who added effects to the accumulated music data) is written into the sound generation area on the output buffer (set in step S52). Secondly, the time at which the length ST is added to the length of the generated amount SR is set to New time ST (step S63). This new time ST forms the starting position of the calculation when the "sound source processing 1" is performed next. Then it is judged whether or not the musical data of 1 output buffer amount has been completed (step S64). If NO Returning to the previous step, if it is YES on the other hand, use "Sound Source Processing 2" described later to separate its output buffer from other output buffers connected to these output buffers, and the reproduction reservation is made in the "output device" ( Step S65). And return to the previous step. Return to step S5 in Fig. 8, if the cause of start ③ occurs, perform "Sound Source Processing 2" (step S10), and proceed on the panel The predetermined state is displayed.

Description of invention (27 ) Shows (step S11). And return to step S3 to repeat the processing below step S3. "Sound source processing 2" also forms part of the "sound source part". The "sound source processing 2" is performed according to the generated request by the "output device" (that is, the external interrupt processing using the DMA controller 11). Figure 13 is a flowchart showing an example of the external interrupt processing performed by the DMA controller. Figure. The external interruption process is the time at which the music data is transferred on the DAC 12 in 1 sample volume (the reproduction sample frequency of the DAC 12) for the DMA controller 11 to perform. This process can be stored in the output buffer 1 buffer The amount of music data is read out for each sample frequency and supplied to the DAC12. Initially, use "Initial Processing" (Figure 9) or "Glycoside Processing 1" (囵 12) to reserve the reproduction in the output buffer in the "Output Device" and the output buffer (referred to as PB) (Output buffer) One sample of music data (the music data indicated by the index PP) currently being read out is sent to the DAC12 (step S71). Next, the index PP is advanced by one sample (step S72), and it is determined whether all the musical data in the output buffers have been transferred to the DAC 12 (i.e., whether the reproduction processing of the output buffers has been completed) (step S73). If it is NO, return to the previous step. On the other hand, when step S73 determines YES, it is determined whether the next output buffer has been reserved for playback (step S74). Due to the influence of other processing, the start of the "sound source" is delayed, even if the output buffer of the sound source data is not written with the "sound source" playback reservation completed, the output buffer of the playback reservation (first set the "initial setting" ”（囵 9） Reproduction (please read the precautions on the back and then fill in this page) —Installed--The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (21.0X: 297mm) _ 30 Central Standard of the Ministry of Economic Affairs A7 _B7_ printed by the Bureau ’s Consumer Cooperative. V. Description of the invention (28) The reserved output balancer, or the output buffer for the reproduction reservation using sound source processing 1) Until all the reproduction processing is completed, you can proceed when step S74 determines YES To step S75, let the finger PB advance to its output buffer. Therefore, as explained in [Countermeasure 3], it is possible to expand the allowable range of the start time of the tone generation processing to prevent the sound from being interrupted when the tone generation processing is delayed. Step S76 after step S75 may cause the output buffer after the reproduction process is completed to be returned to the main path of "sound source processing 2". And return to the previous step 0. On the other hand, since the activation of the "sound source" is greatly delayed, even in the interval where the reproduction processing of the output buffer that has been reserved is completely completed, the writing of the "sound source" is completed to generate musical data If the output buffer still fails to reproduce the reservation, if it is determined to be NO in step S74, the process proceeds to step S77. Step S77 performs noise suppression on the output of the DAC 12 in order to prevent the occurrence of noise. The subsequent step S78 is a request for resetting with respect to "sound source processing 2" (resets requiring musical tone generation processing). And back to the previous step. Fig. 14 is a flowchart showing an example of an "output device j return request (step S76 in Fig. 13). An output buffer returned from the" output device "is initially accepted (step S81). Next, clear the output buffer so that the output buffer already held by the "sound source" is connected to its output buffer (step S82). In this connection, the output buffers are connected to each other in a presumed order to form a larger buffer for processing. Therefore, there is no need for such an output buffer to be physically adjacent to each other in the RAM 5. The step S83 after step S82 is a moving paper sheet that can confirm whether there is a time offset between the "sound source part j and the" output device "and amend the" sound source part ".

Invention description (29) The data of the time required for the return of the "output device" is displayed. And return to the previous step. Fig. 15 is a flowchart showing an example of "sound source processing 2" based on the reset request of the "output device" (step S78 in Fig. 13). Initially, all the data in the audio source register for each audible audio and the data in the output buffer of RAM 5 are completely eliminated (step S91). Subsequently, the same as step S23 to step S25 of "Initial Setting" (圚 9), the initial setting of "Output Device" (Step S92), the reproduction of the 4 output buffers for erasing data is reserved again in "Output Device" (Step S93) When the "output device" is activated, the software timer is started (step S94). And return to the previous step. As described above, when the “sound source processing” of the reset request fails to reserve the output buffer reproduction in the “output device”, as described in [Countermeasure 4], the music generation processing performed by the “sound source section” up to now is interrupted. After the advance reservation for the reproduction to cancel the output buffer is made again in the "output device", the "sound generator" is activated based on the MIDI information supplied later, whereby the tone generation process can be restarted. Therefore, even if the reservation cannot be reproduced in real time, causing temporary confusion of the musical sound, it is possible to immediately restore the sound-generating action of the musical sound and suppress the noise to a minimum. Returning to step S5 of FIG. 8, when the start factor ④ occurs, perform the processing corresponding to its requirements (for example, input event processing on the upper panel of the display 9, or input event processing from the command of the keyboard 8, etc.) (step mule S12), and Perform the corresponding indication on the panel (Step S13). And it returns to step S3 and repeats the process of step S3 and below.

Furthermore, in step S5, when it is judged that two or more starting factors ① to ⑤ occur, the steps are in the order of starting factors ①, ②, ③, ④, ⑤ Processing below S5. Steps S3 to S5 are hypothetical representations of task management that simulates multitasking. In fact, in the process of processing according to the occurrence of arbitrary start factors, when the start factor occurs with a higher priority order , Can be interrupted by other processors (for example, in the process of "sound source processing 1" according to the occurrence of the activation factor ②, you can use the interruption of the activation factor ① to perform "MIDI processing j, etc." Next, the description will be made relative to the above embodiment Examples of changes are as follows.

The above implementation form is shown in step S51 of “Sound Source Processing 1” of 圚 12 every time an internal interrupt signal occurs using a software timer. , The current time GT minus the final time ST at the end of the tone generation processing is set to the amount of generation SR (ie, the ungenerated tone data without the internal interrupt signal is generated in the subsequent opportunity of the internal interrupt signal. All generated) method. This method has the advantage that the generation of ungenerated tone data can be carried out at the earliest. However, this method will cause the internal interrupt signal to occur after the internal interrupt signal has not occurred several times in a row. The amount of musical data generated by chance increases SR. As mentioned above, once the amount of generated sound increases, the time spent by CPU3 when performing the "Sound Source Processing 1" one time increases, so the CPU3 will be affected by the "Sound Source Processing 1". Since it has formed a monopoly for a long time, it is necessary to start processing such as "Sound Source Processing 2" with a lower priority than "Sound Source Processing 1 j" At the time of occurrence, CPU3 was unable to carry out this paper standard.

Invention description (31) When the generated amount SR is increased, when there is less operable time EJ, it will extremely reduce the vocalization frequency of the musical data that can be generated. Therefore, the following is the "I instructions to slowly generate ungenerated musical data Examples of changes are as follows. [Change example 1] This change example uses the software timer to generate an internal interrupt signal (that is, generates a musical tone waveform) as the signal information in place of "Sound Source Processing 1" whenever an internal interrupt signal occurs. (Referred to as the generated implicit command (cue) of the waveform) and corresponding to the number of elapsed time of the internal interrupt signal before the generation of the write processing (called the implicit command) in a predetermined buffer in RAM5 (called the implicit command buffer) deal with). And when writing the implied instruction of waveform generation into implied instruction processing, the amount of tone data generation is determined within a certain range so that the time of tone generation processing is not too long, and the tone data is generated according to the setting, so that the implied instruction buffer The waveform generation implied instruction performs the elimination process (referred to as "sound source processing 1 '") according to the number of its generated amount. Each time the implied instruction generated by the waveform is written into the implied instruction buffer for the above processing, ungenerated musical tone data can be slowly generated. According to the next method, if the internal interrupt signal does not occur multiple times in a row, although the number of implicit commands generated by the waveform in the implicit command buffer can be increased, the music data of the "sound source processing 1 '" once The amount of generated is suppressed within the above certain range, so it will not cause the situation of "sound source processing 1 '" long-term continuous occupation and so on. And it is easy to ensure that the processing with lower priority is performed, and it is possible to prevent the number of vocal channels that generate musical data from being extremely reduced.

The most preliminary" S101 " "Setting" is applied to the process of "Initial setting" (see Fig. 9) in step S1 of circle 8 to clear the data in the above-mentioned implied command buffer of RAM5. The subsequent step S10 2 is to proceed with the step of Fig. 8 The same processing as S2. The next step is ankle S103 which detects the occurrence of the following starting factors. Starting factor ①: MIDI information is supplied from the “sequence program” (see Part 2). Starting factor ②: The use of software timer to start the “source” The internal interrupt signal of "Part". Starting factor ③: Write the implicit command generated by the waveform into the implicit command buffer. Starting factor ④: Detect the processing requirements of the "output device".

On the other hand, when it is judged that the start factor ② (soft «internal interrupt signal of the timer) occurs, proceed to the" implied instruction "of step S108. In the same example, due to the influence of other processing that the CPU3 must perform, the internal interrupt signal may be delayed, or the internal interrupt signal may not occur, etc. Therefore, from the occurrence of the internal signal to the second occurrence of the internal interrupt signal The time is not limited to 10 milliseconds and may exceed 10 milliseconds.) "Implicit instruction processing" is shown in Figure 17, the elapsed time from the occurrence of the previous internal interrupt signal to the occurrence of this internal interrupt signal corresponds to several times 10 milliseconds, Generate multiple times of waveforms to generate hidden instructions (ie, the first one when the elapsed time is more than 10 milliseconds and less than 20 milliseconds, the second one when the elapsed time is more than 20 milliseconds and 30 milliseconds. Including instructions), write the generated waveform to generate implicit instructions (step S120). And return to the previous step. When the "implicit command processing" is completed, the predetermined status display on the screen is performed (step S109), and the procedure returns to step ankle S103. By this, the "implicit command" loads the waveform in the implicit command buffer to generate an implicit command, which causes the start factor ③ to occur. When it is determined in step S105 that the start factor ③ has occurred, the process proceeds to "Glycoside processing 1 '" in step S110.

The subsequent step S123 corresponds to the number of implicit commands generated by the waveform in the implicit command buffer, which determines the amount of generated SR. The number of vocalization channels of music data. More specifically, when the number of implicit commands generated by the waveform in the implicit command buffer is less than a certain value (that is, when the number of internal interrupt signals that do not occur continuously is less than the certain number above), it is decided to perform processing at the start of recording (Figure 10) The number of vocalization frequencies allocated for vocalization is the number of vocalization channels that generate musical data. On the other hand, when the number of implicit commands generated by the waveform in the implicit command buffer is above the certain value (when the number of uninterrupted internal interrupt signals reaches a certain value or more), it is determined that the number of utterances is less than the utterance allocation for recording start event processing The frequency is used as the number of vocal channels that generate musical data. As mentioned above, the reason for reducing the sound channel is that when the internal interruption signal of the continuous performance does not occur several times, the generated tone data increases to a certain degree, so by reducing the sound channel, the time required for "Sound Source Processing 1 '" is shortened by This can cause the generation of music data that has not been generated earlier. In addition, this step S123 is different from step S53 of FIG. 12, and it is not necessary to reduce the number of vocalization channels by the relationship of the operable time EJ (the original modification example was not generated by an internal interrupt signal but in the implicit instruction buffer Loading the waveform generates implicit commands to start the "audio source processing plant", so there is no concept of operable time EJ itself), which will not cause an extremely reduced number of vocal channels.

The subsequent step S136 generates an implicit command for clearing only one waveform in the command buffer. As mentioned above, in the example of 圚 18, the production amount SR of a “sound source processing l'j is fixed at 10 milliseconds (corresponding to 1 out of 10 of the output buffer volume music data). Therefore, it will not be affected by the“ sound source processing 1 '"causes a long-term monopoly on CPU3, so it is easy to ensure that the priority is lower than that of" sound source processing 1' ", and it can prevent the extreme reduction of the number of vocal channels of" sound source processing 1 '" . Next, FIG. 19 is a flowchart showing another example of "sound source processing Γ". The first step S141 is to generate the number of implicit commands corresponding to the waveform loaded in the implicit command buffer, and determine the number of vocalization channels for generating the set SR and generating the tone data. The number of vocalization channels is determined in the same way as step S123 in FIG. The determination of the amount of generated SR is described in more detail as follows. When the number of implied instructions generated by the waveform in the implicit instruction buffer is less than a certain value (that is, when the number of internal interrupt signals that have not occurred consecutively is less than a certain value), the amount of generated SR is determined Is 10 milliseconds. On the other hand, when the number of implied instructions generated by the waveform in the implied instruction buffer reaches the above-mentioned certain value (that is, when the number of internal interrupt signals that have not occurred continuously reaches a certain value), it is decided to set the SR to 20 ms (corresponding to 1 output (2 / 10th of the time of buffering music data). (For a specific example, if the internal interrupt signal has not occurred for more than 20 consecutive times and the number of implied instructions generated by the waveform in the implied instruction buffer has reached more than 20, the number of reservations shown in Figure 7 is reduced from the original 4 to 2. Therefore, it can be decided to set the SR to 20 milliseconds). In addition, the number of implied instructions generated by the waveform in the implied instruction buffer is greater than the above-mentioned certain value. ^ Zhang scale applies to the Chinese national standard ((: Milk) into 4 specifications (210 father 297 mm) _38.

Description of the invention (36) At a degree, within a certain range where the time required for "Sound Source Processing 1 '" is not very long, a larger amount of production SR can be determined. Next, in step S142, the same as step S52 in step 12, set the time ST (in the time that represents the input time of the MIDI message) to one output buffer out of the remaining output buffers other than the output buffer of the initial setting j playback reservation The final time when the tone generation process of the MIDI message is completed on the time axis) is the tone generation area of the previous generation amount SR. The same processing as steps S54 to S65 in FIG. 12 is performed in steps S143 to S154. The second step S155 is Corresponding to the ankle S141 determined that the amount of production SR is a multiple of 10 milliseconds, only clear the number of times (only 1 when the generation SR is 10 milliseconds, and 2 when the generation SR is 20 milliseconds). The waveform in the device generates an implicit command and returns to the previous step. As shown in the example in Figure 19 above, when several consecutive performances fail to generate an internal interrupt signal, the generation of a "sound source processing 1 '" is generated in a "sound source" The length required to process 1 'j is not too long within a certain range to determine the length of more than 10 milliseconds. This not only can achieve the effect shown in the example of Figure 18, but also can make the unproduced musical data earlier when the unproduced musical sound increases Produced.

The processing after the determination of the cause of activation ④ in step S105 (the processing of “sound source processing 2” in step S112 and the processing of step SH3) is in addition to the “sound source processing 2 j” of the “reset request of the output device j (step S78 in FIG. 13) At step S5 of FIG. 8, the same processing as the "sound source processing 2" of step S10 of FIG. 8 and the step S11 of step S10 of FIG. 8 when it is determined that the activation factor ③ occurs. This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm V 39-312776 A7 ____B7_ V. Description of invention (37)) Figure 2 0 represents an example of "sound source processing 2" resetting requirements according to the "output device" Flow chart. In step S161, a sound source register and an output buffer are added to clear all the waveforms in the implicit command buffer in the modified example to generate an implicit command. The next steps are S162 to S164. The same processing as steps S92 to S94 in FIG. 15. And return to the previous step. Return to FIG. 16 to determine the processing after the start factor ⑤, ⑥ occurs in step S105 (steps S114 and S115, step S116 and SU7) are The same processing is performed as steps S12 and S13, and steps S14 and S15 of Fig. 8 when the activation factor ④ and the activation factor ⑤ are determined at step S5 of Fig. 8. [Modification 2] The Ministry of Economic Affairs Central Bureau of Accreditation Bureau Cooperative Printed Bag (Please read the precautions on the back before filling out this page) This modification example is that when the software timer generates an internal interrupt signal, it is determined within the predetermined range that the time required for the tone generation processing is not too long The tone data is generated as a function of the amount of tone data generated, and the amount of tone data is generated (referred to as "sound source processing 1"). When the internal interrupt signal is generated, the above processing can be performed by This slowly generates slightly generated music data. That is, this method uses the generation of the internal interrupt signal as the starting point because the tone generation process is the same as the main path of FIG. 8, but the ungenerated music data cannot be generated all at once. It is gradually produced a little bit different from the "sound source processing 1" in Fig. 12, but the same as the "sound source processing 1 '" in [Modification 1]. Therefore, the CPU 3 does not monopolize the "sound source processing I1'" for a long period of time, and The same effect as [Modification 1] can be achieved. In addition, relative to the activation factor of "Sound Source Processing 1 '" in [Modification 1] (loading the waveform on the implied command buffer to generate this paper scale applies the Chinese national standard (CNS) Eight 4 specifications (210X297mm) L-A7 _B7_ printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of Invention (38) Implicit Directive) The priority order must be lower than the start factor of "implicit command processing" (the occurrence of an internal interrupt signal). In this way, the occurrence of the internal interrupt multiple itself forms the start factor of "sound source processing 1" " To make it easier to prioritize the advantages of the tone generation process. Next, refer to FIGS. 21 to 25 to illustrate the example of this change. In this change example, the main path of the CPU 3 is, except that “sound source processing 1” is used instead of “ The point where the sound source processing 1 is performed is the same as that of FIG. 8. The circle 21 is a flowchart showing an example of "sound source processing 1". In the first step S201, the current time GT on the time axis indicating the input time of the MIDI message is subtracted On the time axis, the input time at the end of the sin according to the completion of the tone processing of the MIDI messages in the input time of the MIDI message is set to the delay amount OR (the amount of time in which no tone data is generated). Next, in step S202, the amount of production SR is determined as a function of the delayed OR. Fig. 22 is a diagram showing an example of the characteristics of the function. In this example, when the amount of delay OR is less than a predetermined value, the SR is set to 10 milliseconds (corresponding to the time of 1 out of 10 of the output buffer volume music tone), but when the amount of delay 0R reaches a predetermined value or more, the The increase in the delay amount 0R causes the SR to increase continuously. In addition, when S SR is generated to reach a predetermined upper limit value SRmax in a range where the time required for the tone generation processing is not too long, the upper limit value SRnax may be, for example, 20 milliseconds or other values. Fig. 23 is a diagram showing another example of the characteristics of this function. In this example, when the delay amount 0R is less than a predetermined value, the SR is set to 10 milliseconds, but when the delay value OR reaches a predetermined value or more, as the delay amount 0R increases, the generated amount does not increase continuously. In addition, when the amount of production SR reaches the time required to prevent musical sounds from being processed, the paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210X297mm X41-(please read the note $ item on the back and fill in this page) . Order 2776 Α7 Β7 Printed by the Consumer Labor Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention (39) When a predetermined upper limit value SRraax is within a long range, even if the OR continues to increase even after the delay, the amount of production SR The upper limit value SRmax is still maintained. In addition, the generation amount SR determined as described above is not only an integer multiple of 10 milliseconds, but also a value with a number relative to the end of the unit. The amount of musical data generated by '1' is not only an integral multiple of 1/10 of the musical data of 1 output buffer as shown in Fig. 5 or Fig. 6, but also can be formed with an amount relative to the number of units. 24 is an example of the amount of musical data generated in this modified example, which is represented by the occurrence of internal interrupt signals. In the same figure, in the first opportunity of the internal interrupt signal in a certain section (0 milliseconds in the figure) ), Producing this Section 1 outputs the tone data of 1 / 10th of the buffered tone data. Also, after the second and third chances of the internal interrupt signal (10th and 20th of the second), the internal interrupt signal occurs The 4th chance (30 seconds in the picture), the ungenerated tone data generates 1 output buffer amount of the tone data of 1.6 points out of 10 points of the tone data (so the total number of 1 in these sectors is generated up to the opportunity Output buffer music data set at 2.6 out of 10, which is represented by 2.6.) Secondly, in the 5th chance of generating an internal interrupt signal (40 milliseconds in the figure), 1 output buffer is generated The music data of 1/5 of 10 of the music data (therefore the opportunity to generate a total of 4.1 out of 10 pieces of music data of the output buffer music data of these sections, the figure is represented by 4.〗 ) .In the 6th chance of the internal interrupt signal (50 milliseconds in the picture), 1 output buffer set tone data is generated 1_4 out of 10 set tone data (so a total of 1 output buffer manager in these sections is generated up to this opportunity Music data 10 wood paper M is being applied National Standard (CNS) Α4 specification (210X297 public shame) 42-—.------ <-^ -— (please read the precautions on the back and then fill in this page) Order the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 printed by the Industrial and Consumer Cooperatives V.

And, the 7th and 8th chances of no internal interruption signal (60, 60) After 70 milliseconds), at the 9th chance (80 milliseconds in the figure) of the internal interrupt signal, 1 output buffer tone data of 1.7 / 10th of the tone data is generated (so the total of these areas is generated up to this opportunity 1 in the segment outputs the music data of the amount of 7.2 out of 10 of the buffered music data, which is indicated by 7.2 in the figure). Secondly, the 10th chance (90 milliseconds of the figure) of the internal interrupt signal is generated, which generates 1.6 output of the tone data of 1.6 out of 10 of the tone data (so the total of these zones is generated within 1 zone 1 Output 8.8 pieces of music data of buffered music data, which is represented by 8.8 in the figure). And in the next section, in the i-th chance (100 milliseconds) of the internal interrupt signal, the remaining output of the previous section of the ungenerated tone data is 1 / 10th of the amount of tone data 1.2 volume of music data, and 0.3 volume of music data of 1/10 of the output buffer volume of the sound data in this section (10.3 in the figure). Secondly, the second chance (110 milliseconds in the figure) of the internal interrupt signal is generated, and the tone data of the amount of 1.4 out of 10 of the buffer data of the 1 output in the current section is generated (so the opportunity is so far) A total of 1 output buffer music sound in the sub-zone is generated in the sub-zone, which is 1.7 / 10 of the music tone, which is represented by 1_7 in the figure). Music data within the scope. In step S203 subsequent to step S202, one of the output buffers, among the output buffers remaining other than the output buffer reserved for "initial setting", is set, and the tone generation area with the generation amount SR before time ST is set.

Description of invention (41) Second In step S204, it is possible to determine the number of vocalization channels to generate glucoside data for SR. The number of vocalization channels can determine one of them as a function of the amount of delay OR. Figure 25 shows an example of the characteristics of this function. In the case where the delay setting OR is less than a predetermined value, the number of vocalization channels CHmax for utterance allocation at the recording start event processing (Figure 10) is formed as the number of vocalization channels that can produce musical data, but when the delay OR is above a predetermined value, As the amount of delay OR increases, the number of vocalization channels that generate musical data decreases to less than CHinax. As mentioned above, when the amount of delay OR is above a predetermined value, the reduction in the number of vocalization channels will shorten the time required for tone generation processing In addition, other examples are to determine the number of vocalization channels in the same way as step ankle S53 in FIG. 12. In step S205 to step S214 after step S204, the same steps as step S53 to step S63 in FIG. 12 are performed. In the subsequent step S215, the volume envelope of the vocalization channel where the recording is terminated is gradually reduced toward 0. Next, in steps S216 to S217, the same processing as the steps S64 to S65 of FIG. 12 is performed. .. and return to the previous step.

As mentioned above, the computer music system is processed even on the 0S that does not have full multitasking capabilities. , Can still prevent the occurrence of situations such as vocal disturbances caused by the delay of the start of the "sound source" caused by other processing effects. Furthermore, the above embodiment is in [Countermeasure 1], and a predetermined number of samples are generated in 1 section Music data. However, this "total" does not necessarily require the completion of the generation of the music data of the predetermined number of samples in 1 section.

As shown in the example of FIG. 6, there will be no internal occurrence in Q6 The ungenerated tone data of the interrupted signal opportunity can be generated immediately before the last opportunity in the 1 section, but even if the last opportunity is still not generated, it can still be generated for the next section (for example, only 10 The second chance is generated by the second and second tone data of the 7th and 8th times, and the remaining 9 and 10 times of the second tone data are generated by the opportunity of the internal interrupt signal in the subsequent section to replace the 10 times as shown in Fig. 6 Chance (100 Boss times) to generate all 4 times of music data not generated). In addition, as shown in the example of [Modification 1] and [Modification 2], the generation of unproduced musical tone data of a certain section can be left in the next section. In addition, in the above-mentioned form of information, in MIDI processing such as recording_start event processing or recording end event processing, data representing control parameters for the control of the "sound source", recording start, and event occurrence time are stored in Each sound source register of each sound channel. However, instead of storing the sound channels of the control parameters and other sound sources in the other sound source registers, the data indicating the channel numbers of the sound channels of the control parameters and the like can be grouped and recorded sequentially. At this time, once the serial data is prepared according to the supply of MIDI information, the musical data can be generated according to this sequence of raw materials. In addition, in the above embodiment, in the "sound source processing 2", the output buffer returned from the "output device" is connected to the output buffer that already holds the "sound source section", so it is in the "sound source processing 1" above One output buffer of music data is generated on the connected output buffers. However, the size of this paper is applicable to the Chinese National Standard (CNS) Α4 specification (210X297mm) L 45--------(please read the precautions on the back before filling in this page). A7 _B7_ printed by the Bureau Staff Consumer Cooperative. V. Invention description (43) Individual output buffers can also be used instead of the above-mentioned connected output buffers. In the above embodiment, the "sound source" is activated first, and the reproduction of the four output buffers is reserved in the "output device j." However, the "sound source" is activated and reserved for the "output device" The number of output buffers can of course also be other than 4. In addition, the number of output buffers provided in the RAM 5 may be an appropriate number more than 1 more than the number of output buffers reserved for the "output device" to start the reproduction of the "sound source" first. The above embodiment is implemented All [Countermeasure 1], [Countermeasure 2], [Countermeasure 3] and [Countermeasure 4]. However, when these countermeasures are implemented independently of each other, it is possible to prevent the delay in the activation of the "sound source" from causing disturbances in the vocalization. Therefore, one of the countermeasures should be implemented tightly, or two or three countermeasures can be combined appropriately. In addition, the above embodiment is to apply the present invention to the sound generation process of the waveform memory method in the soft pulp sound source of the CPU mode, but the software sound source of the CPU mode can also be applied to other suitable tone generation methods. (For example, FM synthesis method, etc.). In addition, the present invention can be applied not only to software sound sources that use the CPU of a computer (that is, a general-purpose computer) for tone generation processing, but can also be implemented by using the CPU of a computer equipped with an appropriate device mounted on a dedicated tone generation device or other special functions Tones in the software sound source system.
