Is related to the editing program.

  Conventionally, editing parameters (sample parameter data) for processing acoustic signal waveform data (wave data) obtained by sampling an acoustic signal waveform input from a microphone or an audio device has been performed. The edited acoustic signal waveform data is used, for example, as a sound source waveform of an electronic music apparatus by combining one or a plurality of data.

At this time, there are cases where it is desired to collectively apply the values of a plurality of parameters for processing one acoustic signal waveform data to other acoustic signal waveform data.
In that case, if you adopt a general operation method, specify the range of the parameter value with the mouse, operate the "Ctrl" key and "C" key at the same time, then press the "Ctrl" key and "V" By simultaneously operating the keys, the parameters are copied and pasted (copy and paste) one by one.
Alternatively, while holding down the “Ctrl” key, specify the range of each parameter one by one with the mouse, then simultaneously operate the “Ctrl” key and “C” key, and then press the “Ctrl” key. And "V" key can be operated simultaneously to copy and paste all at once.
However, even if any operation method is adopted, it is complicated.

FIG. 1 is an explanatory diagram showing an editing screen used in the first embodiment of the present invention. A GUI (Graphical User Interface) is used, and parameter values for acoustic signal processing are input by operating a mouse on a window screen.
1A is an explanatory view showing an editing screen 1 before copying and pasting, and FIG. 1B is an explanatory view showing an editing screen 1 after copying and pasting.
Reference numeral 2 denotes a first parameter set display screen for processing the acoustic signal waveform (WAVE1), and reference numeral 3 denotes a second parameter set display screen for processing the acoustic signal waveform (WAVE2).

In the first and second parameter set display screens 2 and 3, 4 and 9 are the sound signal waveform (WAVE 1) and the sound signal waveform (WAVE 2), respectively, and 4 a and 9 a are lines for displaying the start addresses of loop playback. Reference numerals 4b and 9b denote lines for displaying end addresses.
5 and 10 are data boxes as setting value display areas for inputting a value of a start address (for example, expressed by the number of samples), and 6, 11 are input values of an end address (for example, expressed by the number of samples). This is a data box as a set value display area.

7 and 12 can be copied (copied) with the start address value and the end address value displayed in the data boxes 5 and 6, 10 and 11 described above as a pair. It is a text display indicating that
On the other hand, 8 and 13 can be pasted (paired) as a pair with respect to the values of the start address and end address displayed in the data boxes 5 and 6, 10 and 11 described above. It is a text display indicating that it is enabled.
In the example shown in the figure, a pair (copying) and pasting is performed, but in general, a link (concatenation) group (including a pair) is configured with a plurality of parameters, and the link copying and pasting is performed.

First, a general copy & paste operation will be described.
On the first parameter set display screen 2 shown in FIG. 1A, one of the data boxes 5 and 6 is selected by operating the “Tab” key or the mouse, and a predetermined copying operation, for example, ASCII When a shortcut key operation is performed by pressing the “Ctrl” key + “C” key on the keyboard, the selected value LOOPSTART1 (3065) displayed in the data box 5, for example, is selected and temporarily stored in the clipboard buffer. .
Next, among the data boxes 10 and 11 shown on the second parameter set display screen 3, the data box 10 corresponding to the same parameter LOOPSTART2 as the copied LOOPSTART1 (3065) is moved to the “Tab” key or the mouse. When “Ctrl” + “V” is pressed, the LOOPSTART1 temporarily stored in the clipboard buffer is pasted into the corresponding data box 10.

Next, link copying and pasting will be described.
When a sound source waveform is synthesized by combining acoustic signal waveforms 4 and 9, loop reproduction may be performed in the same range.
In this case, the loop reproduction start address LOOPSTARTj and end address LOOPENDj included in the parameter set of the acoustic signal waveform data j (j = 1, 2) are set to common values between the acoustic signal waveforms 4 and 9. For this reason, a link group is configured in advance and displayed in the parameter set display areas 2 and 3.
In addition, display symbols “]” 14 and 15 indicating that a link group is configured may be displayed on the screen.

One of the data boxes 5 and 6 shown in FIG. In addition, a link copy operation, for example, a shortcut key operation of pressing the “Ctrl” key + “Shift” key + “C” key on an ASCII keyboard is performed. As a result, the values of LOOPSTART1 and LOOPEND 1 constituting the link group are temporarily stored in the clipboard buffer.
Next, in the data box 10 or the data box 11 shown on the second parameter set display screen 3, the data box 10 having the same parameter as the data box 5 previously selected at the time of the link copying operation is displayed as “ Select with the "Tab" key or mouse. In addition, a link pasting operation, for example, a shortcut key operation of pressing the “Ctrl” key + “Shift” key + “V” key on an ASCII keyboard is performed.

As a result, the values of LOOPSTART1 and LOOPEND1 temporarily stored in the clipboard buffer are pasted together as the LOOPSTART2 value of the data box 10 and the LOOPEND2 value of the data box 11 corresponding to each. Is done.
Since LOOPSTART1 ≦ LOOPEND1 at the copy source, LOOPSTART2> LOOPEND2 does not occur at the paste destination, so that the parameter condition for loop reproduction is automatically satisfied.
As shown in FIG. 1B, the same value “3065” as that of the data box 5 is pasted on the data box 10. The same value “6593” as that of the data box 6 is pasted on the data box 11. It is pasted as a parameter setting value for the acoustic signal waveform (WAVE2), not just a value displayed on the setting value display area.

Link copying requires a different selection operation from copying one parameter. However, the selection operation for pasting the link may be a selection operation different from the selection operation for pasting one parameter value, or may be the same selection operation.
In the above description, as shown in the text displays 7, 8, 12, and 13, any of the parameter sets of the acoustic signal waveform data j (j = 1, 2) can be linked and pasted. Was set to be.

However, link copying and link pasting may be disabled by setting.
For example, a link copy enabling / disabling setting area and a link pasting enabling / disabling setting area are provided on the first parameter set display screen 2 and the second parameter set display screen 3. Detecting the user's selection operation for the link copy enable / disable setting area and link paste enable / disable setting area, and setting the link copy disable and link paste disable, respectively. do.

When setting common to the first parameter set and the second parameter set, the link copy enable / disable setting area and the link pasting enable / disable setting area are set to the first parameter set. It may be provided in an area other than the display screen 2 and the second parameter set display screen 3.
The link copy enabling / disabling setting information and link pasting enabling / disabling setting information may be stored in the storage device together with the parameter set.

FIG. 2 is an explanatory diagram showing a data configuration example of acoustic signal waveform data according to the first embodiment of the present invention.
The data (WAVEDATA1) of the acoustic signal waveform (WAVE1) 2 will be described, but the same applies to the acoustic signal waveform (WAVE2) 9.
WAVENAME1 is the name of the data, and DATASIZE1 is the data size. LOOPSTART1 and LOOPEND1 are the start address and end address of loop reproduction as described above.
PAIR-COPY FLG1 is a copy enable flag. PAIR-PASTE FLG1 is a pasting enable flag. In either case, 1 indicates possible and 0 indicates impossible. In the illustrated example, the enabling / disabling is determined according to the acoustic signal waveforms 4 and 9 to be processed, and is determined for each parameter set.
PCMDATA1 is sampled and digitally converted data of the acoustic signal waveform (WAVE1) 2.

  As the above parameter set, the start address and end address of the loop are shown. However, the sound signal waveform data playback range (start address, end address), original pitch (original key), sounding range (key range), output destination, filter settings, envelope generator settings, LFO (Low Frequency) There are various parameters that are necessary to reproduce and sound the sampling data of the acoustic signal waveform, such as the setting value of the Oscillator) and the setting value of the receiving channel of the MIDI interface. From these, a plurality of parameters can be arbitrarily selected to form a parameter set.

FIG. 3 is a block diagram illustrating an example of a hardware configuration that implements an embodiment of the present invention.
In the figure, 21 is a bus and 22 is a CPU (Central Processing Unit). Reference numeral 23 denotes a memory system, which includes, for example, a RAM (Random Access Memory) and a flash memory ROM. A control program and acoustic signal waveform data WAVEDATA1 and WAVEDATA2 shown in FIG. 2 are stored.
When the CPU 22 executes the control program, the acoustic signal processing parameter editing process is realized.
The RAM in the memory system 23 stores parameter setting values.

Reference numeral 24 denotes an operation unit such as an ASCII keyboard or a mouse, and 25 denotes an operation display, which displays the editing screen 1 shown in FIG. The shortcut key operation described with reference to FIG. 1, the “Tab” key, or the data box selection operation with the mouse are realized.
Reference numeral 26 denotes a DSP (digital signal processing unit) which is held in the memory system 23 with respect to the acoustic signal waveform data stored in the memory system 23 or the acoustic signal waveform data input from the ADC / DAC 27 described later. Depending on the parameter settings, loop playback and other signal processing are performed.

Reference numeral 27 denotes an ADC / DAC (analog / digital conversion unit / digital / analog conversion unit) which inputs an analog acoustic signal waveform (audio signal), performs A / D conversion, and sends the analog sound signal waveform (audio signal) to a DSP (digital signal processing unit) 26. The digital output signal from the DSP 26 is D / A converted to output an analog acoustic signal waveform (audio signal) to the outside.
A digital input signal input to the ADC / DAC 27 from the outside and a digital signal output from the ADC / DAC 27 to the outside are input / output through a common line.

28 is a MIDI interface. The sound signal waveform data WAVEDATA1, WAVEDATA2, etc. shown in FIG. 2 can be input from an externally connected personal computer.
Further, when the CPU 22 creates a “program” for generating a sound source waveform based on the sampling data of the acoustic signal waveform processed by the DSP 26 and stores it in the memory system 23, it is input from the MIDI interface 28. It is also possible to generate a musical sound waveform according to the performance data to be played, add an effect according to the effect parameter in the DSP 26, and output it from the ADC / DAC 27 to the outside.

FIG. 4 is a flowchart for explaining the operation of copying (copying) parameters using the editing screen shown in FIG. The processing related to copying is extracted from the acoustic signal processing parameter editing program executed by the CPU 22 shown in FIG.
In S31, it is determined whether SEQFLG1 is 0 or not. Since the initial state is 0, the process proceeds to S32.
In S32, it is determined whether or not there is a selection operation event for one of the copy source data boxes 5 and 6.
If there is a selection operation event, the corresponding, for example, data box 5 is highlighted (highlighted) in S34, SEQFLG1 is set to 1 in S35, and the process returns to S31 through a main routine (not shown). .

Since SEQFLG1 is 1 at this time, the process proceeds from S31 to S33. When the simultaneous pressing of “Ctrl”, “Shift”, and “C” is detected in S33, the process proceeds to S36.
If pair copy is enabled in S36 (PAIR-COPY FLG1 is 1), the process proceeds to S38, and the loop start address (LOOPSTART1) and loop end address (LOOPEND1) are stored in the clipboard buffer. Since the link copying process is completed, the SEQFLG1 flag is set to the initial state 0 in S39, and the process returns to S31 through a main routine (not shown).

On the other hand, when simultaneous pressing of “Ctrl” and “C” is detected in S37, a loop start address (LOOPSTART1) corresponding to one of the data boxes 5 and 6 selected in S32 is selected in S40. ) Or loop end address (LOOPEND1) is stored in the clipboard buffer.
In S36, even when pair copying is disabled (PAIR-COPY FLG1 is 0), the process proceeds to S40 so that only one parameter selected for copying can be copied.
Since the conventional copying process is completed, the SEQFLG1 flag is set to the initial state 0 in S39, and the process returns to S31 through a main routine (not shown).

If the simultaneous pressing of “Ctrl” and “C” is not detected in S37, the process proceeds to S41. If there is any other operation in S41, the SEQFLG1 flag is set to the initial state 0 in S39, the process is returned to the main routine (not shown), and the process according to the other operation is performed, and then the process proceeds to S31 again.
On the other hand, if there is no other operation, the process proceeds to S31 again through a main routine (not shown).

FIG. 5 is a flowchart for explaining an operation of executing a parameter paste operation using the editing screen shown in FIG. This is a process for extracting a paste process from the acoustic signal processing parameter editing program executed by the CPU 22 shown in FIG.
In S51, it is determined whether SEQFLG1 is 0 or not. Since the initial state is 0, the process proceeds to S52.
In S52, it is determined whether or not there is a selection operation event for one of the paste-destination data boxes 10 and 11.
If there is a selection operation event, the corresponding data box 10, for example, is highlighted in S54, SEQFLG1 is set to 1 in S55, the process returns to the main routine (not shown), and the process returns to S51 again.

Since SEQFLG1 is 1 this time, the process proceeds from S51 to S53. When pair paste is enabled in S53 (PAIR-PASTE FLG2 is 1), the process proceeds to S56. When simultaneous pressing of “Ctrl”, “Shift”, and “V” is detected, the process proceeds to S57.
In S57, it is determined whether the loop start address (LOOPSTART1) and the loop end address (LOOPEND1) are stored in the clipboard buffer. If so, the process proceeds to S59.

In S59, the values of the loop start address (LOOPSTART1) and the loop end address (LOOPEND1) stored in the clipboard buffer are written in the data boxes 10 and 11 as LOOPSTART2 and LOOPEND2, respectively.
In S57, when both the loop start address (LOOPSTART1) and the loop end address (LOOPEND1) are not stored in the clipboard buffer, the process proceeds to S60 to display an alarm (warning) window screen.
The alarm is for notifying the user that necessary data is not correctly copied to the clipboard. For example, there is a case where the user tries to paste a pair but has not copied the pair.

When the processes of S59 and S60 are completed, the process proceeds to S61, the SEQFLG11 flag is set to the initial state 0, and the process returns to S51 through a main routine (not shown).
On the other hand, when the pair paste is not enabled in S53 (PAIR-PASTE FLG2 = 0), or when the simultaneous pressing detection of “Ctrl”, “Shift”, “V” is not detected in S56 , The process proceeds to S58.
If the simultaneous pressing of “Ctrl” and “V” is detected in S58, the process proceeds to S62. In S62, the data is temporarily stored in the clipboard buffer at the loop start address (LOOPSTART2) or the loop end address (LOOPEND2) corresponding to one of the data boxes selected in the previous S52 among the data boxes 10 and 11. Value is written, the process proceeds to S61, returns to the main routine (not shown), and returns to S51 again.

If the simultaneous pressing of “Ctrl” and “V” is not detected in S58, the process proceeds to S63. If there is any other operation in S63, the SEQFLG11 flag is set to the initial state 0 in S61, the process is returned to the main routine (not shown), and the process according to the other operation is performed, and then the process proceeds to S51 again.
On the other hand, if there is no other operation, the process returns to the main routine (not shown), and the process returns to S51 again.

In the flowchart described above, unless the operation for instructing the pair paste is detected in S56, even if the loop start address (LOOPSTART1) and the loop end address (LOOPEND1) are copied to the clipboard buffer, both are pasted. The method which does not do is adopted.
However, instead of this, an operation instructing pair copy is detected in S32 of FIG. 4, and as a result, the loop start address (LOOPSTART1) and the loop end address (LOOPEND1) are copied to the clipboard buffer. , It may be considered that the user has the intention of pair paste.

That is, even a conventional operation for instructing a paste of one parameter may be regarded as an operation for instructing a pair paste.
For this purpose, the flowchart shown in FIG. 5 is modified. For example, in S56, the same process as S58 is executed. As a result, if YES, the process proceeds to S57, and if NO, the process proceeds to S63.

4 and 5 (S32 in FIG. 4 and S52 in FIG. 5), the LOOPEDIT screen (the first parameter set display screen 2 and the second parameter set display screen 3 in FIG. 1) is the copy source. It was assumed that it was known in advance whether there was a paste destination.
Whether the LOOPEDIT screen is a copy source or a paste destination may be fixedly set corresponding to each, or may be arbitrarily set by a user operation.
Alternatively, the above-described flowchart may be changed so that it is set according to the order in which the LOOPEDIT screens are opened or the order in which the DATABOX is selected (for example, the first opened LOOPEDIT screen is the copy source). Or use the LOOPEDIT screen of the first selected DATABOX as the copy source).
Also, when the above flowchart is changed and there is a selection operation event for DATABOX, it is not determined whether the copy source or the paste destination, and when the next operation is detected, the operation is related to copy (CTRL, SHIFT, If it is C or CTRL, C), that DATABOX may be set as the copy source, and if it is paste related (CTRL, SHIFT, V or CTRL, V), that DATABOX may be set as the paste destination.

In the first embodiment described above, all the parameters included in the parameter set in the data (WAVEDATA1) of the acoustic signal waveform (WAVE1) 2 shown in FIG. 2 constitute one link group (pair group). It was.
However, if there are 3 or more parameters in the parameter set, you want to copy and link link only for some of the parameters, or create multiple link groups and copy and link link for each link group. Cannot handle the case.
Therefore, in the parameter set in the data (WAVEDATA1) of the acoustic signal waveform (WAVE1) 2 shown in FIG. 2, a plurality of link groups of parameters to be link copied and pasted are provided, and identification information (flag) of each link group is provided. These may be added to parameters belonging to each link group.

In the first embodiment described above, the link copy enable flag (PAIR-COPY) for all the parameters in the parameter set in the data (WAVEDATA1) of the acoustic signal waveform (WAVE1) 2 shown in FIG. FLG1) and link paste enable flag (PAIR-PASTE FLG1) are included.
Therefore, the link copy enable flag and the link paste enable flag may be provided for all parameters, but may be provided for each link group described above.
