[0002]

2. Description of the Related Art Conventionally, some automatic performance data editing devices have an editing function called a quantizing process. The quantizing process is a process for correcting the timing variation of the input automatic performance data. Specifically, for example, when the performer inputs the automatic performance data in real time and then reproduces the automatic performance data, when the performer selects a preset resolution, the automatic performance data is automatically reproduced at a timing according to the resolution. It is a process that is reproduced. Therefore, even when the performer is a beginner in music and cannot input the automatic performance data according to the original beat timing, when the automatic performance data is reproduced, the musical sound is reproduced according to the original beat timing.

[0003]

However, in the quantizing process of the above-mentioned conventional automatic performance data editing apparatus,
The timing of the automatic performance data is only corrected uniformly to the timing of eighth notes or quarter notes, for example. Therefore, the corrected automatic performance data becomes monotonous (mechanical) and is musically uninteresting, that is, there is no subtle timing deviation or a player's peculiarity that cannot be expressed in the score. It was often not. Therefore, although the automatic performance data is reproduced at the correct beat timing, the reproduced musical sound may lose what sounds to the listeners including the performer.

The present invention has been made in view of the above problems, and is an automatic performance data editing process capable of reproducing a musical tone that comfortably resonates in the listener's mind by performing a quantizing process while maintaining the quality of the automatic performance data. The purpose is to provide a device.

FIG. 2 is a diagram showing the data format of the quantize pattern.

The data format of the quantize pattern includes a header P1 that stores a pattern number, a pattern name, a time signature, the number of measures, and the like, a quantizing process timing,
That is, it is composed of a timing sequence P2 indicating the timing of outputting the automatic performance data and an end code P3 indicating the end of the quantize pattern. The quantize timing may be represented by the position within the bar, or may be represented by the time interval from the previous automatic performance data output timing. In this embodiment, the latter expression is used.

The automatic performance data editing apparatus of the present embodiment has a function of creating a quantize pattern (hereinafter, referred to as "quantize pattern creating process") by a single device, reading out a preset quantize pattern and inputting the quantize pattern. A function to correct and record the automatic performance data (hereinafter referred to as "quantize edit processing"),
A desired quantize pattern is read out from a preset quantize pattern, and while the automatic performance data is input, the automatic performance data is quantized,
A function to record the processing result (hereinafter, referred to as "record quantize processing"), a function to read out a preset preset quantize pattern based on already input automatic performance data, quantize it, and reproduce it simultaneously (hereinafter, " It is configured so that it can perform four types of functions (referred to as “playback quantizing processing”).

The quantizing pattern creating process includes a pattern creating mode for actually creating the quantizing pattern described with reference to FIG. 2, a quantizing pattern created by this pattern creating mode, and a quantizing pattern preset in the ROM 9. It has two types of modes: a quantize pattern edit mode for correction.

First, the processing procedure of the quantizing pattern creation processing will be described below with reference to the flow charts of FIGS.

FIG. 3 is a flow chart showing the procedure of the timer interrupt process in the quantize pattern creating process.

In this embodiment, the timer interrupt request is made by the timer 7 in FIG. 1 once every 96 minutes. That is, when the timer 7 measures the time corresponding to the length of 96 minutes, it outputs an interrupt request to the CPU 6, and the CPU 6 receives the interrupt request and shifts the processing from the main routine to the timer interrupt routine. Since the time corresponding to this 96 minute length changes according to the change in tempo, the time interval at which an interrupt request is made changes depending on the tempo.

First, at step S1, the value of the flag RUN indicating the execution state of the quantizing process is discriminated, and when the value is "0", this interrupt process is terminated, while
When the value is "1", the process proceeds to step S2.

In step S2, a counter TIME1 (hereinafter referred to as "TIMER") provided in the RAM 8 of FIG. 1 for counting the timing of quantizing.
"1") is incremented by "1". That is,
The counter TIME1 is used to create the timing sequence P2 of the quantize pattern of FIG. 2 and counts the time between automatic performance data. In the subsequent step S3, a counter BEAT (hereinafter, the content of this counter) provided in the RAM 8 and indicating (counting) the position within one bar is incremented by "1".

Next, in step S4, it is determined whether or not BEAT matches the value corresponding to the time signature. Here, the value corresponding to the time signature is the last value of one bar, that is,
As described above, since this interrupt processing is performed once every 96 minutes, for example, when creating a quantize pattern in 4/4 time, the value "96" means 3/4 time. In the case of, the value is "72". In step S4, when BEAT does not match the value corresponding to the time signature, this interrupt processing is terminated, while BEAA
When T matches the value corresponding to the time signature, BEAT is cleared in step S5, and in the following step S6, a counter MEAS for counting the number of measures (hereinafter, the content of this counter is referred to as "MEAS (MEASURE)") is set. It is incremented by "1" and the process proceeds to step S7.

In step S7, it is determined whether or not the MEAS matches the number of measures set in the quantize pattern creating routine described later. When the MEAS does not match the number of measures, this interrupt process is terminated, while
When MEAS matches the number of measures, step S8
In step S9, the flag END instructing the end of the generation of the quantize pattern is set, and the flag RUN is reset (step S9), and then this interrupt process is ended.

FIG. 4 is a flowchart showing a processing procedure of a subroutine of the quantize pattern forming mode, which is a part of a main routine (not shown).

First, in step S11, the performer sets a pattern number, a pattern name, a time signature, and the number of measures for creating a quantize pattern by a switch (not shown) provided on the panel switch 4 of FIG. Then, the CPU 6 writes the set value in the header P1 described in FIG.

Next, in step S13, the values (TIME1, BEAT, MEAS) of the counters described above are cleared, and in step S14, the process waits until an instruction to create a quantize pattern is issued, and when the instruction is issued, step S1
In step 4, the flag RUN is set and the process proceeds to step S16.

In step S16, it is determined whether or not the timing switch for creating each timing of the timing sequence P2 described in FIG. 2 has been pressed. In this determination, when the timing switch is pressed, the process proceeds to step S17, TIME1 at that time is written at the timing of the timing column P2, and TIME1 is cleared (step S18), and then the process proceeds to step S19.
That is, the time from when the timing switch is pressed to when the timing switch is pressed next time is counted by the TIME1 once every 96 minutes in the interrupt processing routine, and the count value is the timing sequence P.
It is written in the area corresponding to the timing of configuring 2.

In step S19, the value of the flag END is discriminated, and when the value is "0", the setting of the timing sequence P2 has not been completed. Therefore, the process returns to step S16 and the setting of the timing sequence P2 is completed. Step S
The processing from 16 to step S18 is repeated. Therefore,
The player can create each timing of the timing sequence P2 by pressing the timing switch at a desired timing.

On the other hand, in the determination of step S19, when the value of the flag END is "1", the flag END is reset (step S20), and the end code P3 is written as described in FIG. 2 (step S21). This subroutine ends.

FIG. 5 is a flow chart showing the processing procedure of the subroutine of the quantize pattern edit mode.

First, in step S31, the original quantize pattern to be edited is selected. At this time, the quantizing pattern to be selected may be the quantizing pattern created in the quantizing pattern creating mode described above and stored in the RAM 8, or the quantizing pattern preset in the ROM 9 in advance.

Next, in step S32, the quantize pattern selected in the previous step is copied to the edit buffer of the RAM 8. This is to preserve the original quantize pattern so that you can undo or redo during editing.

In the following step S33, the header which is the first data of the quantize pattern is read out and displayed on the display circuit 11 in FIG. 1, and in step S34 the leading timing of the timing sequence P2 is read out and displayed.

FIG. 8 is a diagram showing an example of the quantize pattern displayed on the display circuit 11. In the figure,
The display section of the display circuit 11 is composed of a header display section 11 ₁ , a timing display section 11 ₂ and an edit position information display section 11 ₃ . The above-mentioned pattern number, pattern name, time signature, and number of measures are displayed on the header display section 11 ₁ , and the timing of quantizing for one measure (indicated by “○” in the figure) is displayed on the timing display section 11 ₂ . , the cursor that indicates an edit position, indicating that the following measure is "arrow" is displayed if there is the next measure, the edit position information display unit 11 _3, the number of measures of the cursor position from the top (MEAS ), The number of beats (BEAT), and the number of clocks from the beginning of the beat (CLOCK) are displayed. Here, the length of one clock is 96 minutes, and the number of clocks is calculated and displayed by the CPU 6 using the timing of the timing sequence P2.

Further, in FIG. 8, for convenience of explanation, a cursor switch (L) 4 ₁ and a cursor switch (R) 4 ₂ which are parts of the panel switch 4 for moving the position of the cursor to the left and right are shown. , An up (+) switch 4 ₃ and a down (−) switch 4 ₄ for increasing / decreasing the timing value.

Returning to the flowchart of FIG. 5, step S
At 35, it is determined whether or not the cursor switches 4 ₁ and 4 ₂ are pressed, and when they are pressed, the process proceeds to step S36, and the cursor switch (L) 4 ₁ or the cursor switch (R) 4 ₂
Accordingly reads the timings of 1 only before or after the timing that is currently read, and displays the information in the edit position information display section 11 _3, in step S37, the display position of the cursor, read Move to the timing position.

On the other hand, if the cursor switches 4 ₁ and 4 ₂ are not pressed in step S35, steps S36 and S37 are skipped and the process proceeds to step S38.
In step S38, it is determined whether the up (+) switch 4 ₃ or the down (−) switch 4 ₄ has been pressed,
When the switch is pressed, the value of the timing (clock) is increased or decreased by "1" according to the pressed switches 4 ₃ and 4 ₄ and rewritten (step S39), and the information is rewritten according to the rewritten timing. It is displayed (step S40). Then, the position of the cursor also moves according to the change in the timing. When the beat position or measure moves to the adjacent position due to the timing change, the value of the beat or measure is rewritten, and the data display is changed.

On the other hand, when the up (+) / down (-) switches 4 ₃ and 4 ₄ are not pressed in step S38, steps S39 and S40 are skipped and the process proceeds to step S41. In step S41, it is determined whether or not the editing is to be ended. When the editing is to be ended, the performer presses an editing end switch (not shown) provided on the panel switch 4 so that the CPU
6 gives the instruction. In step S41, if it is desired to continue editing, the process returns to step S35 to repeat the above process, while if it is desired to finish editing, the process proceeds to step S42, in which data in the edit buffer, that is, the quantizing pattern whose timing is changed by the process described above. After copying the data to the predetermined area of the RAM 8, the present subroutine process is terminated.

When the original quantizing pattern is read from the ROM 9 in step S42,
The changed quantizing pattern is written in a predetermined empty area of the RAM 8 with a new name. When the original quantize pattern is read out from the RAM 8, the changed quantize pattern is overwritten on the original quantize pattern, or a new name is given to the RAM 8 separately. Is written in the area.

As described above, according to the quantize pattern creating process, the performer can create a quantize pattern as he / she desires (quantize pattern creating mode), and a part of the quantize pattern preset in the ROM 9 in advance. When you want to correct, you can freely modify it (quantize pattern edit mode). Although the quantize pattern is created by real-time recording in the above-described example, it may be created by applying a step recording method that is well known for recording automatic performance data.

6 and 7 are flow charts showing the processing procedure of the subroutine of the quantize edit processing.

First, in step S51, the start position and the end position for performing the quantizing process are set by the number of measures, for example. The setting method is set, for example, by operating the up (+) switch 4 ₃ or the down (−) switch 4 ₄ . The start position and the end position may be set not only in units of measures but in units of notes, and other switches such as cursor switches 4 ₁ and 4 ₂ or dedicated switches are used as setting switches. You may do it.

Next, in step S52, the RAM 8 or ROM 9 stores a quantizing pattern having a time signature that matches the time signature of the automatic performance data to be quantized.
Select from the quantize patterns stored in. For example, a list of quantize patterns with matching time signatures may be displayed and the user may select from the list. In step S53, the automatic performance data is copied to the edit buffer.

In the following step S54, step S51
The position of the automatic performance data corresponding to the start position set in is searched, and in step S55, the automatic performance data is read from the searched start position and displayed.

Next, in step S56, the header of the selected quantizing pattern is read out and set in a predetermined area of the RAM 8, and in step S57, the leading quantizing timing is read out. Further, in step S58, the next quantizing timing is read out, and in step S59, the current section is determined by the quantizing timing read in the previous step and the timing immediately before it. Here, the current section is a quantize pattern (step S5) corresponding to the currently read automatic performance data (data at the cursor position), as shown in FIG.
2) the intermediate position between the timing position (hereinafter, referred to as “current position”) of the pattern) and the timing position immediately before the current position and the intermediate position between the current position and the timing position after the current position A section to a position.

In the following step S60, the step S
It is determined whether or not the currently read automatic performance data is present in the current section determined by 59, and if the automatic performance data is not in the current section, step S
Returning to step 58, the current section is determined while moving it to the right on the time axis until the automatic performance data is present in the current section. On the other hand, in step S60, when the automatic performance data exists in the current section, the process proceeds to step S61, and the automatic performance data is corrected so as to match the quantizing timing.

Next, in step S62, step S51
It is determined whether or not the quantizing process has been completed up to the end position set in step S3, and if not, step S
After proceeding to 63 and reading out the next automatic performance data, the process returns to step S60. On the other hand, when the quantizing process is completed in step S62, the process proceeds to step S64.
Play the corrected automatic performance data. Then, in step S65, the performer listens to the reproduced automatic performance data,
If it is determined that the quantizing process is acceptable, the process returns to step S52 when the dissatisfaction is satisfied, and the above-described process is repeated. On the other hand, if satisfied, the process proceeds to step S66, and the quantizing process data in the edit buffer is automatically restored. After substituting the performance data, this subroutine processing is ended.

Next, the recording quantizing process will be described with reference to FIG.
This will be described with reference to FIG.

FIG. 10 is a flow chart showing the procedure of timer interrupt processing in this recording quantizing processing.

In step S71, the value of the flag RUN is determined. If the flag RUN is "1", step S71 is executed.
When the counter TIME1 is incremented by "1" at 72 and the flag RUN is "0", step S
72 is skipped and this timer interrupt processing is ended.

FIG. 11 is a flowchart showing the procedure of the subroutine of the actual recording quantizing process.

As described above, in the recording quantizing process, the automatic performance data is input in real time, at the same time the quantizing process is performed, and the result is stored in a predetermined area of the RAM 8.

First, in step S81, data such as the time signature of the automatic performance data to be recorded is set and written in the header. In the following step S82, as in step S52 (FIG. 6) described above, a desired quantize pattern is selected from a plurality of pre-stored quantize patterns that match the data set in step S81. Subsequent steps S83 and S
At 84, similar to steps S56 and S57 described above,
The header of the selected quantize pattern is read and set, and the leading quantize timing is read.

Next, in step S85, the process waits until a start switch (not shown) for recording quantizing is pressed, and when it is pressed, the flag RUN is set in step S86 and then the process proceeds to step S87.

Since the processes of steps S87 and S88 are the same as the processes of steps S58 and S59 (FIG. 7), the description thereof will be omitted. In the following step S89, if the value of the counter TIME1 is not within the current section, step S8
7, the next section is determined to be the current section, and if the value of the counter TIME1 is within the current section, the process proceeds to step S90.

In step S90, it is determined whether or not there is a key event, and when there is a key event, step S90.
Proceed to 91. Here, the key event refers to a key-on or key-off operation by the performer. In step S91,
A value corresponding to the quantize timing is used as the timing (event timing) of the automatic performance data, and the corresponding R
Write in position AM8. When the key event does not occur within a certain current section, the quantize timing values are sequentially added, and the added value is recorded as the timing of the performance data.
At 92, event information (key depression key code, on event code, etc.) corresponding to the key event is written next to the event timing written at the previous step, the counter TIME1 is cleared at step S93, and then the process proceeds to step S94. Here, the data format of the automatic performance data that has been quantized in this recording quantizing process is the one in which the event information is inserted between the respective timings of the timing sequence P2 in FIG. 2, that is, between the event information and the event information. This is a format in which time interval information at which these event information occurs is recorded.

On the other hand, in the determination of step S90, if there is no key event, steps S91 to S
The process of 93 is terminated and the process proceeds to step S94.

In step S94, it is determined whether or not a stop switch (not shown) for ending the recording quantizing process has been pressed. As a result, if the stop switch is not pressed, the process proceeds to step S89 and the counter T
The determination of the current section based on the value of IME1 is repeated. On the other hand, when the stop switch is pressed in step S94, the process proceeds to step S95, the end code is written, the flag RUN is reset in step S96, and the present subroutine ends.

As described above, according to the recording quantizing process, the performer can input the automatic performance data in real time with the quantizing pattern as he / she desires. It is possible to store the automatic performance data with a sense in the memory (RAM 8).

Next, the reproduction quantizing process will be described with reference to FIG.
2 and the flowchart of FIG. 13 to describe.

FIG. 12 is a flow chart showing the procedure of the timer interrupt process in the main reproduction quantize process.

In step S101, the value of the flag RUN is determined, and when the flag RUN is "1", the counter TIME2 for decrementing the quantizing timing.
Is decremented by "1". Continued Step S102
Then, it is determined whether or not the value of the counter TIME2 is "0", and when the counter TIME2 is "0", the next quantizing timing is read (step S104), and the current section is determined in the same manner as in step S59 (FIG. 7) described above. After (step S105), all the automatic performance data existing in the determined current section are output to the tone generator circuit 11 of FIG. 1 (step S106). In a succeeding step S107, it is determined whether or not the read data is an end code, and when it is the end code, in a step S107, a flag END is set to give an instruction to end the reproduction quantizing process, and the interruption process is ended. To do.

On the other hand, when the value of the flag RUN is "0" in step S101, the counter TIM is calculated in step S103.
When the value of E2 is not "0" and the data read in step S107 is not the end code, this interrupt process is ended.

FIG. 13 is a flow chart showing the procedure of a subroutine of the main reproduction quantizing process.

As described above, in the main reproduction quantizing process, the quantizing pattern is read out from the automatic performance data already input and stored in the memory to reproduce it.

First, in step S111, the header of the automatic performance data is read and set. Here, the information such as the time signature set in step S81 of FIG. 11 is written in the header of the automatic performance data, and the information is read and temporarily written in a predetermined area of the RAM 8 of FIG. The subsequent processing of steps S112 to S115 is similar to the processing of steps S82 to S84 of FIG. 11, and thus description thereof will be omitted.

Next, in step S115, the value of the timing read in step S114 is set to the counter TIM.
After storing in E2, in step S116, the process waits until a start switch (not shown) for performing the main reproduction quantizing process is pressed, and when the start switch is pressed, the flag RUN is set in step S117.
That is, when the flag RUN is set, step S11
The quantizing timing read in 5 is decremented in the timer interrupt routine, and the already stored automatic performance data is read at the timing of the quantizing pattern.

Next, in step S118, it is determined whether or not a stop switch (not shown) for ending the main reproduction quantizing process is pressed. If not, the value of the flag END is set in step S119. If it is determined that the value is "0", the process returns to step S118. On the other hand, if the value of the flag END is "1", the flag END is reset in step S120, and step S118 is performed.
Proceed to 121. On the other hand, if it is determined in step S118 that the stop switch is pressed, step S1
Proceed to 21. In step S121, the flag RUN is reset, and then this subroutine processing is ended.

As described above, according to the present reproduction quantizing processing, the data string of the automatic performance data pre-input by the performer by the step input or the like is subjected to the quantizing processing so as to add a musical tone with a musical taste. Can be played.

In the present embodiment, the present invention is applied to the electronic keyboard musical instrument, but the present invention is not limited to this, and may be applied to other electronic musical instruments such as an electronic rhythm musical instrument such as a drum and an electronic stringed musical instrument such as a violin. .

Further, the quantizing process may be performed only for the designated pitch (a plurality of pitches may be designated). This is useful when playing a musical sound whose pitch corresponds to each part of the drum set, such as a drum, and you want to change the timing of the tom-only roll, for example. .

Further, as shown in FIG. 14 (a), there are some cases in which the key-on timings of the automatic performance data are almost the same (indicated by points S ₁ , S ₂ , S ₃ in the figure).
When the quantize pattern is data as shown in FIG. 14 (b), as shown in FIG. 14 (c), the sound at the point S ₄ is centered in the order of key-on and only a minute time (t ₁ , t ₂ ) is reached. The key-on timings may be shifted forward and backward. At this time, the times t ₁ and t ₂ may be set, or the point S in FIG.
₄ may be shifting time t _1, t ₂ and time in the top. Further, the order of arrangement of the sounds is not limited to the order of the original data, and may be arranged in the order of high pitch or low pitch.

Further, instead of performing the quantizing process so that the automatic performance data completely matches the timing of the selected quantizing pattern, the quantizing process may be performed so as to approach the timing of the quantizing pattern.
