Abstract

PROBLEM TO BE SOLVED: To make it possible to read out the same musical sound (MS) waveform data at the time of reproducing performance information by the same form as that for storage by repeatedly reading out MS waveform data by a repeated form indicated by the setting of repeated reading and stopping the reading of data at timing indicated by reading stop timing. SOLUTION: Performance information 1 is divided into two performarace information, i.e., performance information 1' and performance information 1". The information 1' is obtained by changing 'reading duration' in the data of the information 1 to reading duration 1' for ending the reading of MS waveform data at extraction start time. Similarly 'reading start time' in the data of the information 1 is changed to reading start time 1" for starting reading from extraction stop time and 'reading duration' in the data of the information 1 is changed to reading duration 1" for ending the reading of MS waveform data at reading end time determined by the reading start time 1 and reding duration 1 of the information 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an electronic musical instrument,
More specifically, the present invention relates to an electronic musical instrument with an improved storage method for storing performance information.

[0002]

BACKGROUND OF THE INVENTION Tone waveform data is assigned to each of a plurality of operators generally called "pads", and the tone waveform data assigned to the operated pad is assigned according to the operation of the pad. At the same time, information indicating that the pad has been operated is stored as performance information for automatic performance, and by playing back the stored performance information, the corresponding musical tone waveform data can be read. An electronic musical instrument has been proposed by the present applicant.

In such an electronic musical instrument, a read start position, a repeated read start position, a read end position, and whether or not to perform repeated read are set for each musical tone waveform data. The following two types of reading modes can be arbitrarily selected.

(1) First reading mode (when repetitive reading is not set) Reading of musical tone waveform data is started from a reading start position, and reading is completed to a reading end position of the musical tone waveform data. Then, the reading is stopped as it is.

(2) Second readout mode (when it is set not to perform repetitive readout) The reading of the musical tone waveform data is started from the reading start position and is read to the reading end position of the musical tone waveform data. When the operation is completed, the musical tone waveform data is repeatedly read out by returning to the read start position of the tone waveform data repeatedly until the operation of the pad is released. That is, whether the tone waveform data is read in response to the pad operation or the tone waveform data is read in accordance with the reproduction of the stored performance information, the tone waveform data is set for the tone waveform data.
The tone waveform data is read based on the settings of the read start position, the repeated read start position, the read end position, whether or not to repeat the read, and which tone waveform data is assigned to the pad.

[0006] Repetitive reading of certain musical tone waveform data is referred to as "loop reading", and each repetition at the time of loop reading is referred to as "loop".

[0007] As a storage method for storing information corresponding to musical tone waveform data read in response to the operation of the pad as performance information for automatic performance, the operated pad is There has been proposed a method of storing only two timings, ie, a read start timing and a read stop timing of corresponding tone waveform data.

According to this method, even when loop reading is performed, only two timings, that is, a read start timing and a read stop timing of musical tone waveform data, are stored.

For this reason, after storing the performance information played in a certain reading mode of the musical tone waveform data, the musical tone waveform data is stored in order to record another performance information played in another reading mode of the musical tone waveform data. If the settings of the readout mode, such as the readout start position, the repeated readout start position, the readout end position, and whether or not to perform repeated readout, are changed, the previously stored performance information is reproduced. The tone waveform data is read out in a manner different from that at the time of storage. That is, there is a problem that the musical tone waveform data cannot be read out in the same state as at the time of storage, and that consistency cannot be maintained between when the performance information is stored and when the performance information is reproduced.

Also, when the setting of the correspondence between the pad and the musical tone waveform data is changed, the same problem as described above occurs.

That is, after storing performance information based on operation of a pad associated with certain musical sound waveform data,
When the setting of the correspondence between the pad and the musical sound waveform data is changed for the purpose of storing another musical information with another musical sound waveform data associated with the pad, when the previously stored musical information is reproduced, the memory is stored. The tone waveform data different from the time is read. In other words, the same musical tone waveform data as in the case of storage cannot be read out, and there is a problem that consistency between performance information storage and reproduction cannot be maintained.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an electronic musical instrument according to the present invention will be described in detail with reference to the accompanying drawings. In the electronic musical instrument according to the present invention, reading of musical tone waveform data is instructed. Each time the musical tone waveform data is instructed to be read out, data relating to the readout of the musical tone waveform data (“tone waveform data”, “start point”, “loop point”, “end point”, and “loop”) is performed. Are stored as a set, so by referring to such data,
The musical sound waveform data specified when the performance information is stored is read from the read start position set at the time of storage in the loop read mode set at the time of storage. FIG. 1 is a block diagram showing the overall configuration of such an electronic musical instrument according to the present invention.

The electronic musical instrument is configured to control the entire operation by using a central processing unit (CPU) 10. The CPU 10, a program memory 12, a working memory 14, Performance information memory 1
6, a waveform memory 18, an operation panel 20, and a digital / analog (D / A) converter 22.

Here, the operation panel 20 has a pad 30 which is 16 push buttons indicated by numerals 1 to 16 in FIG. 1 (the pad 30 corresponds to the numerals 1 to 16 in FIG. 1). 1 to 16), a storage (REC) operator 32 for designating a storage mode as a mode of the electronic musical instrument, and a reproduction mode as a mode of the electronic musical instrument. (PLAY) operator 34, a stop (STOP) operator 36 for returning from the storage mode or the playback mode to the pad performance mode as a mode of the electronic musical instrument, and various settings changed or stored. The other operator group 38 used for editing the performance information that is present, and the setting state by operating the various operators described above and the display for editing the performance information are provided. A screen display unit 40 to perform is provided.

That is, in this electronic musical instrument, the operation state of various operators provided on the operation panel 20 is CP.
The content displayed on the screen display 40 provided on the operation panel 20 and monitored by the U10 is controlled by the CPU 10.

In this electronic musical instrument, when the pad 30 provided on the operation panel 20 is operated (pressed and released), performance operation information indicating that the pad 30 has been operated (pressed and released). Will be generated. Such performance operation information is interpreted as a musical sound waveform data read start instruction or a read stop instruction in accordance with the musical tone waveform data read mode set on the pad 30 described later.

The components of the electronic musical instrument will be further described.
The working memory 14 is a working memory of the CPU 10, and various settings are also stored in this memory.

The performance information memory 16 is a memory for storing performance information based on the operation of 16 pads 30 provided on the operation panel 20.

Further, the waveform memory 18 is a memory in which 100 kinds of tone waveform data as digital data are stored in advance. The 100 types of musical sound waveform data stored in the waveform memory 18 are numbered from 1 to 100 and managed. Other operator group 38 of operation panel 20
By the operation described above, it is possible to perform setting for associating arbitrary musical sound waveform data with each of the 16 pads 30 of the operation panel 20.

The musical sound waveform data stored in the waveform memory 18 includes various musical instruments called so-called "phrases" which are played for a certain period of time (for example, two bars of a certain musical piece). The obtained instrument sounds, the instrument sounds obtained when the wind instrument is played only once or the stringed instrument is played only once, the voices such as singing and shouting, and the sound effects such as the rain sound. Can be That is, any sound data may be stored in the waveform memory 18 as musical sound waveform data, and it is not particularly necessary to store sound data of musical instruments.

In this electronic musical instrument, the musical tone waveform data stored in the waveform memory 18 is read out by the CPU 10, converted into an analog signal by the digital / analog converter 22, and output. The sound is emitted into space as a sound that can be heard through a sound system (not shown) including a speaker and the like.

Next, the operation of the electronic musical instrument in each mode will be described. First, in the pad playing mode, the operated pad 3 is operated in accordance with the operation of the pad 30.
The tone waveform data corresponding to 0 is read from the waveform memory 18 under the control of the CPU 10.

Here, the manner of reading out the musical tone waveform data when the pad 30 is operated is as follows.
Three types of modes, "ATE (gate)", "TRIGGER", and "DRUM (drum)" are set.

(1) GATE (Gate) The reading of the musical tone waveform data is started in response to the pressing of the pad 30, and the pressing of the pad 30 is released, that is, the reading of the musical tone waveform data is stopped when the pressing of the pad 30 is stopped. Is done.

(2) TRIGGER (trigger) The reading of the tone waveform data is started in response to the pressing of the pad 30, and the reading of the tone waveform data is continued even if the pressing of the pad 30 is released, and the pad 30 is pressed again. The reading of the musical tone waveform data is stopped in response to. (3) DRUM (Drum) The reading of the musical tone waveform data is started in response to the pressing of the pad 30, and when the reading is performed up to the end point (described later) set in the musical tone waveform data, it is automatically performed. The reading of the tone waveform data is stopped.

In this electronic musical instrument, it is preset for each pad 30 which of the readout modes of GATE, TRIGGER and DRUM is to be set.
In addition, the setting of the readout mode can be arbitrarily changed for each pad 30 by operating the other operator group 38.

Here, the tone waveform data will be described. As shown in FIG. 2, a start point, an end point, and a loop point described below are set in advance in each tone waveform data. Whether or not to perform loop reading is set in advance, and these settings for each tone waveform data can be arbitrarily changed by operating the other operator group 38.

The start point indicates a reading start position of the musical tone waveform data according to the operation of the pad 30. The start point is operated by operating the other operation elements 38.
If the point is set at an arbitrary position in the musical tone waveform data, for example, in the middle of the musical tone waveform data, it is possible to start reading from the middle of the musical tone waveform data.

The end point indicates a stop position for reading out the tone waveform data in accordance with the operation of the pad 30. The end point is set to an arbitrary position in the tone waveform data, for example, by operating the other operation elements 38. If the setting is made in the middle of the tone waveform data, it is possible to stop the reading in the middle of the tone waveform data.

The loop point is 2 in the case where a loop of musical tone waveform data is read out in accordance with the operation of the pad 30.
It indicates the beginning of the repetition after the first time, that is, the read start position of the loop.

The start point, end point and loop point are designated by information indicating a relative position from the head of the musical tone waveform data.

The setting as to whether or not to perform the loop readout indicates whether or not the musical tone waveform data is to be read out in a loop according to the operation of the pad 30.

The position of the loop point may be before, after or the same as the position of the start point. However, the position of the end point needs to be set to be after both the position of the start point and the position of the loop point.

Therefore, when performing loop reading,
When the musical tone waveform data is read out to the end point, the operation of returning to the loop point and continuing to read out the musical tone waveform data is repeated.

As to the manner of reading out the tone waveform data when the pad 30 is operated, the tone waveform data corresponding to the pad 30 for which DRUM is set is read out, for example, so that a loop readout setting is made. No loop reading is performed.

From the above, the manner in which the musical tone waveform data is read when the pad 30 is operated is as follows.

(1) In the case of GATE and not loop reading The reading of the tone waveform data is started from the start point in response to the pressing of the pad 30, and the pressing of the pad 30 is released or the reading of the tone waveform data is started. When the operation is performed up to the end point, the reading of the tone waveform data is stopped.

(2) In the case of GATE and loop readout In response to the pressing of the pad 30, reading of the tone waveform data is started from the start point, and when the pressing of the pad 30 is released, the reading is stopped. When the reading of the musical tone waveform data is performed up to the end point, the reading position is returned to the position designated by the loop point, and the reading of the musical tone waveform data is continued.

(3) In the case of TRIGGER and not loop reading The reading of the musical tone waveform data is started from the start point in response to the pressing of the pad 30, and the reading is continued even if the pressing of the pad 30 is released. Then, when the pad 30 is pressed again, or when the reading of the musical tone waveform data is performed to the end point, the reading of the musical tone waveform data is stopped.

(4) In the case of TRIGGER and loop reading-out The reading of the musical tone waveform data is started from the start point in response to the pressing of the pad 30, and the reading is continued even if the pressing of the pad 30 is released. Then, when the pad 30 is pressed again, the reading is stopped. When the reading of the musical tone waveform data is performed up to the end point, the reading position is returned to the position designated by the loop point, and the reading of the musical tone waveform data is continued.

(5) In the case of DRUM The reading of the musical tone waveform data is started from the start point in response to the pressing of the pad 30, and the reading is continued even if the pressing of the pad 30 is released. Then, when the reading of the musical tone waveform data is performed up to the end point, the reading of the musical tone waveform data is stopped. Also, the setting for loop reading is ignored.

Next, the storage mode will be described. In the storage mode, the musical tone waveform data is read out in accordance with the operation of the pad 30 in the same manner as in the pad performance mode. Is stopped in the performance information memory 16 as performance information.

The reproduction mode will be described. In the reproduction mode, the performance information stored in the performance information memory 16 is read, and the reading of the musical tone waveform data is started in accordance with the timing of starting the reading of the musical tone waveform data. The reading of the musical tone waveform data is stopped according to the timing of stopping the reading of the musical tone waveform data.

Here, the performance information memory 16 will be described with reference to FIG.
There are provided storage areas numbered as information numbers 1, 2, 3,... In chronological order, and each storage area stores a set of performance information. Then, 1 stored in each storage area
The performance information of the set is composed of seven data of "tone waveform data", "start point", "loop point", "end point", "loop", "read start time" and "read duration". It is configured.

To explain these seven data in detail, "tone waveform data" is data indicating tone waveform data to be read, and any number from 1 to 100 assigned to each tone waveform data is stored. Is what is done.

For the "start point", "loop point", "end point" and "loop", whether or not to read out the start point, loop point, end point and loop in the musical tone waveform data Are copied.

The "reading start time" is data indicating the reading start time of the musical tone waveform data, and the "reading duration" is data indicating the duration from the start of the reading of the musical tone waveform data to the stop of the reading. Note that "read start time"
Indicates the elapsed time from the point in time when the pad 30 is first pressed after the memory mode is set as the reference time.

In this electronic musical instrument, 1
Only one musical tone waveform data can be read out, and while another musical tone waveform data is being read in accordance with the operation of a certain pad 30, the operation of another pad 30 is invalidated. That is, in this electronic musical instrument, two or more musical tone waveform data are not simultaneously read.

Here, the method of storing in the performance information memory 16 will be described later in detail with reference to the flowcharts shown in FIGS. 4 to 6. When the reading of the waveform data is started, a new set of performance information is added, and the number indicating the musical tone waveform data corresponding to the pad 30 is stored as “musical tone waveform data”. The start point, loop point, end point of the corresponding musical sound waveform data and each setting of whether or not to read out the loop are set to “Start point”, “Loop point”, “End point”.
Points and loops, respectively,
Further, the time when the pad 30 is pressed, that is, the time at the start point is stored as the “read start time”.

When the pressing of the pad 30 corresponding to the musical tone waveform data being read is released (G
ATE), when the pad 30 is pressed again (in the case of TRIGGER), or when the musical tone waveform data is read out to the end point (in the case of DRUM), the time from the start of reading to the time point is read. "Reading duration" for the latest performance information
Is stored as

Since the performance information corresponding to the pressing of the pad 30 is stored in the order in which the pads 30 are pressed, the performance information is stored in the performance information memory 16 in the order of "reading start time". Therefore, when the performance information is read out, the performance information can be read out in the order of "read start time" by reading the performance information in the order stored in the performance information memory 16, but the performance information should be read out. If the performance information can be read out in order, it can be handled as time-series performance information, and the performance information need not be stored in the performance information memory 16 in the order in which the performance information should be read. For example, if the performance information is not stored in the performance information memory 16 in the order of “read start time”, the performance information is read out in the time indicated by referring to the “read start time j” attached to the performance information. What should I do?

Next, the processing in the storage mode according to the present invention will be described in detail with reference to the flowcharts of FIGS. Since the processing in the pad playing mode and the reproduction mode are not related to the present invention, detailed description thereof will be omitted and only the outline will be described.

First, referring to the flow chart of the pad pressing (REC) routine shown in FIG. 4, processing performed when performance operation information indicating that any pad 30 has been pressed in the storage mode is generated. Will be described.

In this pad pressing (REC) routine, first, the pressed pad 30 is set to GATE or DRU.
It is determined which of M and TRIGGER is set (step S402).

If it is determined in step S402 that GATE or DRUM has been set,
The generated performance operation information is interpreted as an instruction to start reading the musical tone waveform data, and the musical tone waveform data corresponding to the pressed pad 30 is read out from the start point (step S404). After that, the musical tone waveform data is read one sample at a time toward the end point by another process (not shown) executed for each sampling period.

Subsequent to step S404, in the performance information set next to the latest performance information set in the performance information memory 16, the number indicating the tone waveform data that has been read out in step S402 is set as "tone waveform data". Remember,
The start point, loop point, end point, and whether or not to perform loop reading set in the musical tone waveform data are set as “start point”, “loop point”, “end point” and The time when the pad 30 was pressed, that is, the time at the start point is stored as a "read start time" (step S40).
6). Further, the value of the variable indicating "elapsed time" is cleared to 0, the counting of this variable is started (step S408), and the pad pressing (REC) routine is ended. Thereafter, the variable indicating the elapsed time is incremented by one by another process (not shown) executed every predetermined cycle. The value of the variable indicating the "elapsed time" is stored in the performance information memory 16 later as the "reading duration".

Also, in step S402, TRI
If it is determined that GGER is set, it is determined whether or not the musical tone waveform data corresponding to the pressed pad 30 is being read (step S410).
If it is determined that the data is not being read out, the generated performance operation information is interpreted as an instruction to start reading out the musical tone waveform data.
The same processing is performed as when it is determined that UM is set.

On the other hand, if it is determined in step S410 that the tone waveform data is being read, the generated performance operation information is interpreted as an instruction to stop reading the tone waveform data, and the reading of the tone waveform data being read is stopped. Then, the value of the variable indicating the "elapsed time" is stored as the "reading duration" of the latest performance information set in the performance information memory 16 (step S414), and the pad pressing (REC) routine is terminated. I do.

When any one of the pads 30 is pressed in the pad performance mode, various data are stored in the performance information memory 16 in the processing shown in FIG. 4 (steps S406 and S414).
In addition, only the process excluding the process of clearing the "elapsed time" and starting counting up (step S408) is performed.

Next, referring to the flowchart of the end point arrival (REC) routine shown in FIG.
Processing performed when the read position of the musical tone waveform data being read in the storage mode reaches the end point of the musical tone waveform data will be described.

In the end point reaching (REC) routine, first, the pad 30 corresponding to the musical sound waveform data reaching the end point is set to GATE, TRI.
It is determined whether the setting is GGER or DRUM (step S502).

If it is determined in step S502 that GATE or TRIGGER is set, it is determined whether or not loop reading is set for the tone waveform data that has reached the end point (step S502). S504).

If it is determined in step S504 that loop reading has been set, the reading position of the tone waveform data that has reached the end point is moved to the loop point (step S5).
06). As a result, the musical tone waveform data that has reached the end point is read again from the loop point toward the end point.

When the processing in step S506 is completed, the end point arrival (REC) routine is completed.

On the other hand, in step S502, the DRUM
Is determined to have been set, or it is determined in step S502 that GATE or TRIGGER has been set, and
If it is determined in step 4 that the loop readout is not set, the reading of the tone waveform data that has reached the end point is stopped (step S51).
0), the value of a variable indicating “elapsed time” is stored in the performance information memory 1
The latest readout information set is stored as the "readout duration" (step S512), and the end point arrival (REC) routine is terminated.

In the pad performance mode, when the reading position of the musical tone waveform data being read reaches the end point of the musical tone waveform data, the "reading duration" is stored in the musical performance information memory in the processing shown in FIG. time"
Only the processing excluding the processing of storing (step S512) is performed.

Next, the pad pressure release (RE) shown in FIG.
C) A process performed when performance operation information indicating that any of the pads 30 has been released in the storage mode is generated will be described with reference to a flowchart of a routine.

In the pad pressing release (REC) routine, first, the pad 30 whose pressing has been released is applied to the GAT.
It is determined whether E, TRIGGER or DRUM has been set (step S602).

If it is determined in step S602 that GATE has been set, the generated performance operation information is interpreted as an instruction to stop reading the sound waveform data, and the tone corresponding to the pad 30 whose pressure has been released is released. It is determined whether or not the waveform data is being read (step S604). If it is determined that the tone waveform data corresponding to the pad 30 from which the pressing is released is being read, the tone waveform is being read. The data reading is stopped (step S606).

Then, the value of the variable indicating the "elapsed time" is stored as the "reading duration" of the latest performance information set in the performance information memory 16 (step S608), and the pad press release (REC) routine is terminated. I do.

On the other hand, in step S602, TRI
When it is determined that GGER or DRUM has been set, or in step S602,
Is determined to have been set, and at step S6
If it is determined in 04 that the tone waveform data corresponding to the pad 30 whose pressing has been released is not being read, the pad pressing releasing (REC) routine ends without performing any processing.

When the pressing of any of the pads 30 is released in the pad performance mode, the process shown in FIG. 6 stores the "reading duration" in the performance information memory 16 (step S608). Only the processing excluding is performed.

When the stop (STOP) operator 36 is operated to return from the storage mode to the pad performance mode, up to which performance information set in the performance information memory 16 has been stored. And returns from the storage mode to the pad playing mode.

Next, the processing in the reproduction mode will be described. The processing in the reproduction mode may be the same as the well-known automatic performance technique.

That is, in the reproduction mode, the performance information is sequentially read from the beginning to the end of the performance information memory 16, and the tone waveform data is read based on the read performance information.

More specifically, the playback (PLAY) control 3
In response to the operation of No. 4, the first set of performance information is read, and the time when the playback (PLAY) operator 34 is operated is set as a reference time, and the elapsed time from the time, that is, the time measurement based on the start of playback is measured. Start. If the "reading start time" of the set of performance information to be read matches this time, the musical sound waveform data indicated by the "musical sound waveform data" of the musical information set is replaced with the "start point" of the musical performance information set. , And the measurement of the elapsed time from that point is started.

When the "reading duration" of the set of performance information to be read coincides with the elapsed time, the reading of the musical tone waveform data being read is stopped, and the read timing for the next set of performance information is reached. And when the read timing comes, the same processing as described above is repeated.

If data indicating that the musical tone waveform data is to be read out in a loop is stored in the "loop" of the performance information set, the reading up to the "end point" of the performance information set has been completed. Sometimes, the read position of the musical tone waveform data is set to the "loop
To the "point" position.

In the pad performance mode, the performance information memory 16 is operated by operating the other operation group 38.
Can be edited.

First, "erase", "delete time", "copy" and "insert" are provided as edit items.

"Erase" deletes an arbitrarily designated range of musical tones generated by instructing the reading of the musical tone waveform data by the performance information, that is, the erase of the musical tone waveform data instructed to be read by the performance information. This is to prevent reading of an arbitrarily specified range.

Here, by specifying a specific set of performance information,
When the set of performance information is "erased", the specified set of performance information is deleted from the performance information memory 16, and all the sets of performance information behind the deleted performance information are moved forward one by one. Will be packed. This makes it possible to prevent the musical tone waveform data that has been read out from the erased performance information from being read out.

It is also possible to designate any two times during the performance by "erase" and to prevent the reading out of the musical tone waveform data which has been read at the time between the times.
Further, in this case, the range not to be read can be specified in the middle of the performance information.

In the following, referring to FIGS. 7A and 7B, the middle part of the musical tone waveform data to be read out by the performance information 1 shown in FIG.
That is, an example of “erasing” will be described.

First, the performance information 1 starts reading musical tone waveform data from the readout start time 1 as the “readout start time” until the time defined by the readout duration 1 as the “readout duration”. The musical tone waveform data is read out in a loop. The "start point" of the musical tone waveform data to be read out in the performance information 1 is indicated as SP_1, the "loop point" is indicated as LP_1, and the "end point" is indicated as EP_1. Show.

Here, with respect to the musical tone waveform data instructed to be read out by the performance information 1, the other operator group 3
A case will be described in which arbitrary extraction start time and extraction stop time are specified by the operation of No. 8, and the musical tone waveform data in the range specified by these extraction start time and extraction stop time is not read.

In this case, the performance information 1 shown in FIG. 7A is divided into performance information 1 'and performance information 1''shown in FIG. 7B. At this time, the “reading duration” of the data of the performance information 1 is
The readout duration 1 'changed so that the readout of the musical tone waveform data ends at the extraction start time is referred to as performance information 1'. The “reading start time” of the data of the performance information 1 is changed to the reading start time 1 ″ changed so that the reading of the musical tone waveform data is started from the extraction stop time. Read duration ''
At the readout end time determined by the readout start time 1 and the readout duration 1 of the performance information 1, the readout duration 1 ″ is changed so that the reading of the musical tone waveform data is completed. ·point"
Is changed to SP · P_1 ″, which is changed to be the reading position at the stop time of the extraction of the musical tone waveform data read by the performance information 1, and is referred to as performance information 1 ″.

At this time, the start point SP_
1 ″ is obtained by the following arithmetic expression.

S · P_1 ″ = L · P_1 + [(removal stop time−read start time 1) − (E · P_1−S · P_
1)-(E-P_1-L-P_1) × k] Here, k in the above-mentioned operation expression is an integer part of the operation result K by the following operation expression.

K = [(removal stop time-read start time 1)
− (E · P_1−S · P_1)] / (E · P_1−L ·
P_1) Then, the performance information 1 'is stored in place of the performance information 1, the performance information stored after the performance information 1 is shifted one by one, and the performance information 1''is stored in an empty portion. Good.

Next, "delete time" deletes an arbitrarily designated range of musical tones generated by instructing reading of musical tone waveform data by performance information. That is, the arbitrarily designated range of the musical tone waveform data read out by the performance information is deleted, and the part after the deleted range is connected to the part before the deleted range.

Here, when a set of performance information is designated and the set of performance information is "time deleted", the specified set of performance information is erased from the performance information memory 16 and the erased set of performance information is deleted. Are moved forward by one after being shifted by "reading duration" of the erased performance information set by all the "read start times" of all the performance information sets that were behind. . As a result, for example, the same effect as that obtained by cutting out a part of a tape on which a musical sound is recorded and attaching the tapes before and after the cut-out can be obtained.

As in the case of the "delete", any two times during the performance are designated by the "time deletion", and the tone waveform read out at the time sandwiched between the times is not read out. You can also connect before and after that. Then, in this case, the performance information is divided into two as in the case of "erasing".

However, in the case of “time deletion”, “deletion”
Is different from the above, the reading start time 1 '' of the performance information 1 ''
The "readout start time" of the performance information after that is adjusted to the takeout start time, and each "readout start time" of the performance information after that is shifted forward by the "time deleted" time.

Next, "copy" is performed so that an arbitrarily designated range of musical tones generated by instructing reading of musical tone waveform data by performance information is generated at another time. An arbitrarily designated range of the musical tone waveform data designated to be read by the information is read at another time.

Here, when a set of performance information is specified and the set of performance information is "copied", the same set of performance information as the specified set of performance information is specified in the performance information memory 16. It is overwritten and stored at the time position. At this time, the “read start time” is the designated time.

Also, as in the case of "erase", "copy"
, Two arbitrary times during the performance can be designated, and the musical tone waveform read out at the time sandwiched between the times can be read out at another time.

Hereinafter, with reference to FIGS. 8A and 8B, the middle part of the musical tone waveform data instructed to be read by the performance information 1 shown in FIG. 8A will be read at another time. That is, an example of “copying” will be described.

As in the case of FIG. 7 (a), the performance information 1 shown in FIG. 8 (a) starts reading the musical tone waveform data from the read start time 1 as the "read start time" It is assumed that the musical tone waveform data is loop-read until the time defined by the reading duration 1 as “time”. The "start point" for the musical sound waveform data to be read out in the performance information 1 is set to S.
P_1, and the "loop point" is L-P_1
, And the “end point” is indicated as EP_1.

Here, the musical tone waveform data to be read out by the performance information 1 is used for the other operator group 3
Performance information 2 (FIG. 8 (b)) which designates an arbitrary extraction start time and an extraction stop time by the operation of FIG. 8 and instructs to read out the musical tone waveform data in the range specified by the extraction start time and the extraction stop time. To the other operator group 3
The case where the data is stored so as to be reproduced at another time arbitrarily designated by the operation 8 will be described.

In this case, first, by specifying the extraction start time and the extraction stop time, the S.T. as the "start point" of the newly extracted musical sound waveform data is set.
P_2, LP_2 as a “loop point”, EP_2 as an “end point” and read duration 2 as a “read duration” are respectively obtained by the following arithmetic expressions.

S · P_2 = L · P_1 + [(takeout start time−readout start time 1) − (E · P_1−S · P_1) −
(E-P_1-L-P_1) × k] L-P_2 = L-P_1 E-P_2 = E-P_1 Reading duration 2 = Removal stop time-Removal start time However, k in the above equation is as follows: This is an integer part of the operation result K by the operation expression.

K = [(take-out start time-read-out start time 1)
− (E · P_1−S · P_1)] / (E · P_1−L ·
P_1) Then, the read start time 2 of the performance information 2 is designated as an arbitrary time by operating the other operator group 38, and the “read start time” of the performance information memory 16 is set to the read start time 2
Is detected, the subsequent performance information is shifted backward by one from the subsequent performance information of the detected performance information, and the performance information 2 is stored in an empty place.

The "reading start time" and "reading duration" of the preceding performance information among the performance information detected at this time.
If the readout stop time determined by the above is later than the readout start time 2 which is the “readout start time” of the performance information 2, the readout stop time of the previous performance information among the detected performance information is the readout time of the performance information 2. The “reading duration” of the preceding performance information of the detected performance information is adjusted to match the start time 2, and the “reading start time” of the subsequent performance information of the performance information detected at this time is If the readout time is earlier than the readout stop time defined by the “readout start time” and “readout duration” of the performance information 2, the “readout start time” of the performance information after the detected performance information is The "read start time" of the performance information after the detected performance information is adjusted to match the read stop time, and the performance information 2
At the time when the reading of the performance information 2 is stopped before the “reproduction” is performed, the position of the musical tone waveform data that has been read out by the performance information after the detected performance information is referred to as the “start point” of the performance information after this. Set to.

Next, "insertion" is similar to "copying", but the musical tone waveform data to be read before copying at the copy destination position is placed behind by the copying time. "Copy" in that it is read out of place
And different.

In this electronic musical instrument, when an instruction to edit the contents stored in the performance information memory 16 is issued, in the first editing mode, the screen display 40 of the operation panel 20 is displayed as shown in FIG. The contents stored in the performance information memory 16 are displayed. Thus, the user designates a set of performance information to be edited while viewing the screen display of the screen display 40. At this time, one set of performance information can be specified, or a plurality of sets of continuous performance information can be specified. After that, editing is performed by executing one of the editing items. Done.

In this electronic musical instrument, when an instruction to edit the contents stored in the performance information memory 16 is issued,
In the second editing mode, the contents stored in the performance information memory 16 as shown in FIGS. 7 and 8 are displayed on the screen display 40 of the operation panel 20. Then, the user operates the other operation group 3 while watching the screen display on the screen display 40.
8 is used to arbitrarily designate the extraction start time and the extraction stop time. Thereafter, the editing is performed by executing one of the editing items.

In this electronic musical instrument, every time reading of the musical tone waveform data is instructed by pressing the pad 30, data relating to the reading of the musical tone waveform data instructed to be read ("musical tone waveform data", "start "Point", "loop point", "end point", "loop", "read start time", and "read duration" are stored as a set of performance information.

Therefore, even after the performance information is stored by the operation of the pad 30, even if the musical tone waveform data different from the previous one is associated with the pad 30, the musical tone waveform data different from the previous one can be read out by the pad performance. When the performance information is reproduced, the same musical tone waveform data as that when the performance information is stored is read out, so that the consistency between the storage and the reproduction of the performance information can be maintained.

Even if the setting for determining the manner of reading out the tone waveform data set in the tone waveform data after the performance information is stored is changed, the tone waveform set when the performance information was stored when playing the performance information is changed. The musical tone waveform data is read based on the data read mode, and consistency can be maintained between performance information storage and reproduction.

For example, after the performance information is stored by operating the pad 30, the start point of the musical tone waveform data associated with the pad 30 is started so that the musical tone waveform data is read out from a position different from the previous position by the pad performance. Even when the performance information is changed, when the performance information is reproduced, the reading out of the musical tone waveform data is started from the same position as when the performance information is stored.

Similarly, after the performance information is stored by the operation of the pad 30, the loop of the tone waveform data is read out in a section different from the previous one by the pad performance, so that the tone waveform data of the tone waveform data associated with the pad 30 is read out. Even if the loop point and the end point are changed, when the performance information is reproduced, the loop of the tone waveform data is read in the same section as when the performance information is stored.

Similarly, after the performance information is stored by the operation of the pad 30, the loop reading has been performed by the pad performance instead of the loop reading, or the loop reading has been performed. Even if the setting of whether or not to perform the loop readout of the musical tone waveform data associated with the pad 30 is changed in order to perform the loop readout because of the absence, the performance information is not reproduced. If loop reading is performed when information is stored, loop reading is performed. If loop reading is not performed when performance information is stored, tone waveform data is read without loop reading.

Further, it is possible to edit performance information relating to a part of a series of repetitions at the time of loop reading.

The above-described embodiment may be modified as described below.

(1) In the above embodiment, the timing of stopping the reading of the musical tone waveform data is determined by the "reading start time" and the "reading duration" of the set of performance information. Without being
Instead of the “reading duration”, a “reading stop time” indicating the reading stop timing by itself may be provided. In this case, the performance information for instructing the start of the reading of the musical tone waveform data and the performance information for instructing the stop of the reading may be defined separately.

In the above embodiment,
Although the timing is defined based on a predetermined time common to all performance information such as "readout start time" and the time elapsed from the reference, the present invention is not limited to this. The timing may be defined based on a time difference between sets of information. For example, instead of the “read start time”, a “time difference” indicating a time difference from the immediately preceding set of performance information may be provided.

In the above embodiment, the precision of the time management of the performance information is not particularly specified, but the time may be managed with a fixed value, for example, 1 millisecond as a minimum unit. Alternatively, time management may be performed with a time interval corresponding to the specified performance tempo, for example, 1 / 96th of a quarter note as a minimum unit. If time management is performed at time intervals corresponding to the specified performance tempo, the accuracy of the time management changes according to the specified performance tempo.

In short, in the present invention, any management method may be adopted as long as the timing at which the reading out of the musical tone waveform data is started and the timing at which the reading out of the musical tone waveform data are stopped are defined by the performance information. It is.

(2) In the above-described embodiment, only one tone waveform data can be read at a time. However, the present invention is not limited to this. A plurality of tone waveform data may be read at a time. .

In the above-described embodiment, the performance information of only one track is stored / reproduced in the case of a conventional automatic performance apparatus. However, the present invention is not limited to this. You may be made to store / reproduce the performance information for minutes.

(3) In the above-described embodiment, when loop reading is performed, the loop is returned from the end point to the loop point. Alternatively, the start point may be set without providing the loop point. May be returned. Alternatively, a loop point is provided, but it may be possible to set whether to return to the loop point or the start point.

Also, in the above-described embodiment, by setting the start point and the end point in the musical tone waveform data, reading is started from the middle of the musical tone waveform data, and the reading is stopped halfway. However, the reading may be started from the beginning of the musical tone waveform data and stopped at the end of the musical tone waveform data without setting the start point and the end point.

In short, the present invention can be applied as long as loop reading is performed.

(4) When editing performance information, the performance information may be graphically displayed. For example, the horizontal axis represents the time lapse along with the progress of the performance, and each set of performance information is
The head is positioned at the position of the horizontal axis corresponding to the reading start time, and is displayed as a graphic whose length is extended corresponding to the reading duration. At this time, the set of performance information obtained by normal reading, which is not loop reading, and the set of performance information obtained by loop reading are clearly distinguished and displayed, so that it is possible to easily determine which set of performance information is obtained by repeated reading. You may.

(5) In the above-described embodiment, the performance information to be edited is specified only in the pad performance mode, that is, in a state in which the storage and reproduction of the performance information are stopped. However, the present invention is not limited to this. None, while playing performance information,
That is, while reading out the musical tone waveform data to be edited, the performance information relating to the musical tone waveform data being read may be designated as the editing target by performing a predetermined designation operation.

(6) In the above-described embodiment, various musical instruments are played for a certain period of time (for example, two bars of a musical piece) by loop-reading out the tone waveform data. Although the phrase as a musical instrument sound can be repeatedly generated, automatic performance data for sequentially instructing to play various musical instrument sounds for a certain period of time (for example, two measures of a certain music) is repeatedly reproduced. Of course, the present invention may be applied to the case where phrases are repeatedly generated. In this case, different automatic performance data is assigned to each pad 30, and the corresponding automatic performance data is reproduced in accordance with the operation of the pad 30, and a tone is reproduced based on the reproduced automatic performance data. I do. And
When the automatic performance data is designated to be loop-reproduced, if the reproduction of the automatic performance data is performed to the end while the automatic performance data is designated by the operation of the pad 30, the automatic performance data at that time is obtained. What is necessary is just to return to a predetermined repetition position, such as the head of data, and to continue reproduction.

In the storage mode, which automatic performance data is to be reproduced, the reproduction start position in the automatic performance data, the repetition position when the automatic performance data is repeated, the end position when the automatic performance data is turned over, the automatic performance data Information for instructing whether or not the data is to be repeatedly played back, and the playback start timing and the playback stop timing of the automatic performance data are stored as performance information.

(7) In the above embodiment, 1
In one device, a pad 30 is provided as input means for inputting an instruction to start generating a musical tone or a musical tone sequence and an instruction to stop generating a musical tone or a musical tone sequence, and a performance information memory is provided as a means for storing performance information. However, it is needless to say that the present invention is not limited to this, and these may be configured as separate devices and connected via communication means such as MIDI.

(8) In the above embodiment, the storing of new musical tone waveform data in the waveform memory 18 has not been particularly described, but the musical tone waveform data is inputted from the outside and stored in the waveform memory 18. You may make it. At this time, an analog / digital converter is provided for externally inputting tone waveform data. The tone waveform of the analog signal is converted into a digital signal by the analog / digital converter, and the waveform memory is controlled under the control of the CPU 10. 1
8 or an interface for exchanging digital data with an external device is provided,
It is conceivable that musical tone waveform data of a digital signal is stored in the waveform memory 18 under the control of the CPU 10.

In the latter case, not only musical sound waveform data but also performance information is exchanged with an external device via the interface, and the performance information input from the outside is stored in the performance information memory 16. Is also good. In this case,
When performance information is input from the outside, the contents of the performance information are automatically checked to determine the musical tone waveform data designated to be read out, and the musical tone waveform data is also transferred from an external device to the waveform memory 18. May be stored. In this way, when the performance information set in the external device is fetched, the musical sound waveform data to be used in the performance information is automatically fetched along with the performance information. This makes it easy to read the musical tone waveform data specified by the performance information when reproducing the captured performance information.

The musical tone waveform data acquired from the external device may be associated with an arbitrary pad 30 so that the musical tone waveform data acquired by operating the pad 30 can be read out. For example, by designating an arbitrary set of performance information in the same procedure as for editing performance information, and operating an arbitrary pad 30,
And a pad 30 which designates musical tone waveform data which is indicated to be read out in the designated set of performance information.
Should be assigned to

(9) In the above embodiment, the information based on the operation of the pad 30 is used as the performance information. However, it goes without saying that the performance information is not limited to this.

For example, information based on the performance of the keyboard may be used as the performance information, and the start timing and the read stop timing of the musical tone waveform data may be determined by the performer independently of the performance operation of the pad 30 or the keyboard. What is specified and input may be used as performance information.

(10) Needless to say, the above-described embodiments and the various modifications described in the above (1) to (9) can be appropriately combined.

[0151]

Since the present invention is constructed as described above, after setting the performance information, the setting of the read-out mode of the musical tone waveform data and the setting of the correspondence between the performance operator and the musical tone waveform data are set. Even when the performance information is changed, the same musical tone waveform data can be read out in the same manner as when the performance information is stored, and it is possible to maintain consistency between the time when the performance information is stored and the time when the performance information is reproduced. It has the effect.
