That is, in the electronic musical instrument shown in FIG.
The whole operation is controlled by the PU 10. An audio signal (tone signal) input from the outside is subjected to A / D conversion by the analog / digital converter 14 as waveform data under the control of the CPU 10. It is stored in the waveform data storage area of the RAM 18. The waveform data stored in the waveform data storage area of the RAM 18 is read out by the regenerator 22, D / A converted by the digital / analog converter 24, and output as an audio signal (tone signal). is there.

FIG. 2 shows the configuration of the operation panel 20. The operation panel 20 has numerals 1 to 3 on FIG.
16, sixteen pad operators 30, a clip board operator 32, a bank switching operator 34,
A sampling operator 36, a delete operator 38, a staff operator 40, a yes operator 42,
A No (No) operator 44 and numerals 0 to 9 in FIG.
A numeric keypad 46 composed of ten keys indicated by a symbol and a liquid crystal display device (LCD) 48 as a display are provided.

Here, the pad operator 30 is assigned with waveform data, and the numerals 1 to 1 in FIG.
6, pad numbers 1 to 16 are assigned and managed. Then, in response to the operation of each pad operator 30, the waveform data assigned to the operated pad operator 30 is reproduced.

The clip board operator 32 is an operator used to change the assignment of waveform data to the pad operator 30. Waveform data is temporarily assigned when the assignment is changed.

Each of the pad operators 30 and the clip board operators 32 is self-illuminating, and is turned on when waveform data is assigned, and turned off when no waveform data is assigned. Thus, the operator to which the waveform data is assigned and the operator to which no waveform data is assigned can be identified at a glance.

When the lit pad operator 30 or clipboard operator 32 is operated, the waveform data assigned to the operated operator is reproduced. Even when the operator 30 or the clipboard operator 32 is operated, the waveform data is not reproduced.

There are nine types of patterns for assigning waveform data to each pad operator 30, and in this electronic musical instrument, these patterns are referred to as "banks". Each time the bank switching operator 34 is operated, the banks are switched in a predetermined order, so that an arbitrary bank can be selected. The nine types of banks are managed with bank numbers 1 to 9 assigned thereto.

The sampling operator 36 is used to record a sampling signal for recording an externally input audio signal.
This is a control for instructing to shift to the mode,
It is made self-illuminated.

The delete operator 38 is an operator used when canceling the assignment of the waveform data assigned to the pad operator 30.

When there is a pad operator (empty pad operator) 30 to which no waveform data is assigned, the staff operator 40 operates in the bank of the pad operator (empty pad operator) 30. The pad operator 30 whose pad number is larger than the pad number of the child (empty pad operator) 30 and the pad operator 30 of the bank whose bank number is larger than the bank number of the bank of the pad operator (empty pad operator) 30 are assigned. This is an operator used when the assigned waveform data is sequentially reassigned to the vacant pad operators 30 so that the waveform data is intensively assigned to the pad operators 30 having the smaller pad numbers in the banks having the smaller bank numbers. .

A ten key 46 is used to designate a bank number to which waveform data is reassigned by the stuff operator 40.

The LCD 48 displays various messages and has an upper and lower display screen.
A message indicating the current mode is displayed on the upper display screen 48a, and a message indicating the current mode is displayed on the lower display screen 48b.
A message prompting the user to make a selection and a message indicating the state in the current mode are displayed.

The Yes operation element 42 is an operation element operated when giving a Yes (Yes) response to the message displayed on the LCD 48, and a No operation element 44.
Is No to the message displayed on the LCD 48.
This is an operator to be operated when making a (No) answer.

Next, the RAM 18 will be described.
As described above, the RAM 18 is provided with a working area, a waveform data storage area, a pad operator management map storage area, a current bank number storage area, and the like required for processing.

FIG. 3 conceptually shows a format of the pad operator management map stored in the pad operator management map storage area.

As shown in FIG. 3, the pad operator control map includes, for each bank of bank numbers 1 to 9 and for each pad operator 30 of pad numbers 1 to 16, the corresponding pad operator 30 of that bank. The information indicating the storage position of the waveform data (waveform data storage position) assigned to the information and the information indicating whether the waveform data is assigned (whether the waveform data is assigned) are stored.

Here, each waveform data is stored in the waveform data storage area of the RAM 18, but since the time length of each waveform data is arbitrary, the waveform data storage area is variable with respect to each waveform data. A long storage area is allocated. For this reason, in the pad operator control map, for each pad operator 30, in which storage position of the waveform data storage area the waveform data corresponding to the pad operator 30 is stored (waveform data storage position) Is stored, the pad operator 30 and the waveform data are associated with each other.

Although the clip board operator 32 is not specifically shown, the pad operator 30 described above is not shown.
The storage area similar to the pad operator management map of RAM 1
8, information indicating a storage position of the waveform data and information indicating whether or not the waveform data is allocated are stored.

When the pad operator 30 and the clipboard operator 32 are operated, the storage position of the waveform data is obtained based on the information indicating the storage position of the waveform data, and the reproduction of the waveform data at the storage position is started. Regenerator 22
, The reproduction of the waveform data is started.

When the reproduction has been performed to the end of the waveform data, the reproducer 22 stops the reproduction.

FIG. 4 conceptually shows a current bank number storage area. The current bank number storage area stores the bank number (current bank number) of the currently selected bank (current bank). ) Is stored.

That is, when bank switching is instructed by operating the bank switching operator 34, the contents stored in the current bank number storage area are stored in the bank switching operator 3
By the operation of No. 4, the current bank number which is the bank number of the bank for which the switching is instructed is rewritten.

When the pad operator 30 is operated, the bank number corresponding to the current bank number in the pad operator management map is determined based on the current bank number stored in the current bank number storage area. The area corresponding to the pad operator 30 thus set is referred to.

Next, the processing when the sampling operator 36 is operated in the performance mode will be described with reference to the flowchart of the sampling operation (performance mode) processing shown in FIG.

That is, when the sampling operator 36 is operated in the performance mode, the processing shown in the flowchart of the sampling operation (performance mode) processing of FIG. 5 is executed.

In the flowchart of the sampling operation (performance mode) processing, first, at step S502
At the time, "sampling mode" is displayed on the upper display screen 48a of the LCD 48, and the sampling operator 36 is blinked to indicate that the mode has shifted to the sampling mode.

When the processing of the start 502 is completed, the flow advances to step S503 to refer to the pad operator control map, and to refer to the pad operator (free pad) to which no waveform data is assigned in the bank of the bank number corresponding to the current bank number. ) Search for 30. Upon completion of the process in the step S503, the process proceeds to the step S504, and the process proceeds to the step S504.
At 503, it is determined whether there is a pad operator (empty pad) 30 to which no waveform data is assigned.

In step S504, the pad operator (empty pad) 30 to which no waveform data is assigned
When it is determined that there is a pad operator, the pad operator 30 having the smallest pad number among the pad operators (empty pads) 30 to which no waveform data is assigned is selected as the pad operator 30 to which the waveform data is assigned. , The pad operator (empty pad) 30 blinks (step S).
506), and shifts from the performance mode to the sampling standby state in the sampling mode (step S).
508), the sampling operation (performance mode) process ends.

In the state before the sampling operator 36 is operated, the pad operator 30 to which the waveform data is assigned in the current bank is turned on.
The pad operator 30 to which no waveform data is assigned in the current bank is turned off, and the sampling operation (play mode) causes the pad operator 30 to which new waveform data is to be assigned to flicker. . Therefore, the user can identify at a glance which pad operator 30 is in which state.

On the other hand, at start 504, a pad operator to which no waveform data is assigned (an empty pad)
If it is determined that there is no “30”, “pad selection” is displayed on the lower display screen 48b of the LCD 48 to urge the user to select the pad operator 30 (step S510). The operation waits until the operator 30 or the bank switching operator 34 is operated (step S512).

If either the pad operator 30 or the bank switching operator 34 has been operated, the flow advances to step S514 to operate the pad operator 3
0, which of the bank switching operators 34 is detected.

If the operation of the bank switching operator 34 is detected in step S514, the process proceeds to step S514.
Proceeding to 516, the "pad selection" display on the lower display screen 48b of the LCD 48 is erased to switch the bank, and the pad operator 3 to which the waveform data is assigned in the new bank by referring to the pad operator management map.
In addition to turning on 0, the pad operator (empty pad) 30 to which no waveform data is assigned is turned off. Then, the process returns to step S503, and the pad operator (empty pad) to which waveform data in a new bank is assigned. 30 search processing is performed.

On the other hand, when the operation of the pad operator 30 is detected in step S514, the operated pad operator 30 is selected as the pad operator 30 to which the waveform data is to be assigned, and the lower display of the LCD 48 is displayed. Screen 4
The display content of 8b is changed from “pad selection” to “overwrite?”, And the operated pad operator 30 blinks (step S518). The "overwrite?" Display asks the user whether the waveform data already assigned to the pad operator 30 is to be deleted and new waveform data can be assigned.

Then, the process proceeds to step S522, where Ye
It is determined whether or not the s operation element 42 has been operated.

If it is determined in step S522 that the Yes operation element 42 has been operated, the "pad selection" display is erased, and a transition is made to the sampling standby state (step S508), and this sampling operation (performance mode) is performed. The process ends.

On the other hand, in step S522, Yes
If it is not determined that the operation element 42 has been operated,
Proceeding to step S524, it is determined whether the No operator 44 has been operated.

In step S524, No operator 4
If it is determined that No. 4 has been operated, step S51
The display returns to the "pad selection" display state of 0.

On the other hand, if it is not determined in step S524 that the No operator 44 has been operated, the process returns to step S522.

Although not shown, if the bank switching operator 34 is operated after the transition to the sampling standby state, the pad operator 30 which has been selected as the target to which the waveform data is allocated is selected. The state is released (returned to the display state before selection), and the bank is switched in the same manner as the above processing (step S51).
6), a process of searching for the pad operator (empty pad) 30 to which the waveform data is assigned (step S503)
Return to

Similarly, when the pad operator 30 is operated after shifting to the sampling standby state,
The selection state of the pad operator 30 which has been selected so far as the target to which the waveform data is to be allocated is released, and a process of determining whether or not the newly operated pad operator 30 is an empty pad is performed. If the pad operator 30 is an empty pad, the process proceeds to step S506 and subsequent steps. If the newly operated pad operator 30 is not an empty pad, the process proceeds to step S510 and subsequent steps.

In this case, since the assignment status of the waveform data to each pad operator 30 is displayed, the user can easily designate a pad operator 30 to which no waveform data has been assigned yet. it can.

That is, when the sampling operator 36 is operated in the performance mode, the pad data 30 to which no waveform data has been assigned yet in the current bank, that is, an empty pad operator 30, is automatically selected. The pad operator 30 is to be assigned new waveform data.

If there is no vacant pad operator 30, or if the user desires to assign waveform data to another pad operator 30 or a pad operator 30 of another bank, an arbitrary pad The operator 30 or an arbitrary pad operator 30 in an arbitrary bank can be assigned.

The pad operator 30 to which the waveform data is to be assigned is made to blink, so that the user can identify at a glance which pad operator 30 is to be assigned. It is.

Next, the processing when the sampling operator 36 is operated in the sampling standby state will be described with reference to the flowchart of the sampling operation (standby state) processing shown in FIG.

That is, when the sampling operator 36 is operated in the sampling standby state, the processing shown in the flowchart of the sampling operation (standby state) processing in FIG. 6 is executed.

This sampling operation (standby state)
In the processing flowchart, first, in step S6
In 02, storage of waveform data input from the outside is started. By the process of step S602, the waveform data input by the process for each sampling cycle (not shown) is stored in the waveform data storage area of the RAM 18.

When the processing in step S602 is completed, L
"Sampling" is displayed on the lower display screen 48b of the CD 48.
Is displayed, and the sampling operator 36 and the pad operator 30 to which the selected waveform data is assigned are turned on (step S604).
The state shifts from the standby state to the sampling state (step S606), and the sampling operation (standby state) processing ends. That is, when the sampling operator 36 is operated in the sampling standby state, sampling is started.

Next, referring to the flowchart of the sampling operation (sampling state) process shown in FIG.
6 will be described.

That is, when the sampling operator 36 is operated in the sampling state, the processing shown in the flowchart of the sampling operation (sampling state) processing in FIG. 7 is executed.

In the flowchart of the sampling operation (sampling state) processing, first, in step S702, storage of waveform data is stopped.

Upon completion of the process in step S702, the flow advances to step S704 to store the stored waveform data in the pad operator 30 selected as the current bank allocation target.
Assign to Specifically, information indicating the storage position of the stored waveform data and the waveform data are assigned to the column corresponding to the pad operator 30 selected as the allocation target of the pad operator management map for the current bank. Is stored.

When the processing in step S704 is completed, L
Change the display contents of the display screen 48b at the bottom of the CD 48 to "End
Resampling? (Step S706),
It waits until one of the pad operator 30, the Yes operator 42, and the No operator 44 is operated (step S708).

Then, the process proceeds to a step S710, where the pad operator 30, the Yes operator 42 and the No operator 4
It is determined which of 4 has been operated.

If it is determined in step S710 that the pad operator 30 has been operated, the process proceeds to step S7.
Proceeding to 12, the operated pad operator 30 is a pad operator (empty pad) 3 to which no waveform data is assigned.
It is determined whether it is 0 or not. In step S712, if the operated pad operator 30 is not the pad operator (empty pad) 30 to which no waveform data is assigned, that is, if waveform data is assigned to the operated pad operator 30, The waveform data assigned to the operated pad operator 30 is reproduced (step S714), and then a standby state (step S708).
Return to

Therefore, the user can determine whether or not the currently stored waveform data is appropriate by operating the pad operator 30 to which the waveform data is newly assigned after the end of the sampling.

At this time, since the waveform data is reproduced even when another pad operator 30 is operated, new waveform data can be compared with already sampled waveform data.

Also, in step S710, Yes
If it is determined that the operation element 42 has been operated,
In addition to displaying "performance mode" on the upper display screen 48a of 48, the display on the lower display screen 48b is deleted (step S716), and the mode is shifted to the performance mode (step S716).
718), this sampling operation (sampling in progress) process ends.

If it is determined in step S710 that the No operator 44 has been operated,
8, the display on the lower display screen 48b is erased, and the mode shifts to the sampling standby state (step S720).
This sampling operation (sampling state) processing is terminated.

That is, when the sampling operator 36 is operated in the sampling state, the sampling is stopped,
The sampled waveform data can be reproduced according to the operation of the pad operator 30, and the sampling can be restarted according to the operation of the No operator 44.

If the operated pad operator 30 has been operated, the flow advances to step S806 to reproduce the waveform data assigned to the operated pad operator 30.
This pad operation (performance mode) processing ends.

That is, when the pad operator 30 to which the waveform data is assigned in the current bank is operated while the clip / board operator 32 is not operated, the assigned pad operator 30 is assigned to the operated pad operator 30. This is to reproduce the waveform data that has been set. With this process,

It is determined whether or not waveform data is assigned to 0.

If it is determined in step S810 that the operated pad operator 30 is a pad operator (empty pad) 30 to which no waveform data is assigned in the current bank, the flow advances to step S812 to execute clipping. The waveform data assigned to the board operator 32 is assigned to the operated pad operator 30 in the current bank. Specifically, information indicating the storage position of the waveform data assigned to the clipboard operator 32 and the waveform data are stored in the column corresponding to the operated pad operator 30 in the pad operator management map for the current bank.

Note that the processing contents of the clip board operation (performance mode) processing are the reverse of the processing contents of the pad operation (performance mode) processing shown in FIG.

That is, in the flowchart of the clip board operation (performance mode) processing, first, in step S902, it is determined whether or not the pad operator 30 is being operated.

If it is determined in step S902 that the pad operator 30 is not being operated, the process proceeds to step S902.
Proceeding to 904, it is determined whether waveform data has been assigned to the clipboard operator 32.

If it is determined in step S904 that waveform data has been assigned to the clipboard operator 32, the flow advances to step S906 to reproduce the waveform data assigned to the clipboard operator 32. Then, the clip board operation (performance mode) processing ends.

In other words, when the clip board operator 32 to which the waveform data is assigned is operated while the pad operator 30 is not operated, the clip
It reproduces waveform data assigned to the board operator 32. By this processing, a performance using the clip board operator 32 is performed.

On the other hand, if it is determined in step S904 that waveform data has not been assigned to the clipboard operator 32, the clipboard operation (performance mode) process is terminated.

If it is determined in step S902 that the pad operator 30 is being operated, the process proceeds to step S908, where the operated pad operator 30 is
It is determined whether the current bank is a pad operator (empty pad) 30 to which no waveform data is allocated.

If it is determined in step S908 that the operated pad operator 30 is a pad operator (empty pad) 30 to which no waveform data is assigned in the current bank, the clip board operation is performed as it is. (Performance mode) The process ends.

On the other hand, in step S908, the operated pad operator 30 is replaced with a pad operator (empty pad) 3 to which no waveform data is assigned in the current bank.
If it is determined that the value is not 0, that is, if the waveform data is assigned to the pad operator 30 operated in the current bank, the process proceeds to step S910, and
It is determined whether waveform data is assigned to the board operator 32.

That is, in a state where the waveform data is assigned to the pad operator 30 operated in the current bank,
When the clip board operator 32 is operated while the pad operator 30 is operated, the clip board operator 3
It is determined whether or not waveform data is assigned to 2.

If it is determined in step S 910 that no waveform data has been assigned to the clipboard operator 32, the process proceeds to step S 912, where the waveform assigned to the pad operator 30 operated in the current bank is determined. Data is assigned to the clipboard operator 32. Specifically, regarding the clip board operator 32, the pad operator 30 operated in the current bank
And information indicating the storage position of the waveform data assigned to the current bank, and information indicating that the waveform data has been assigned, and a column corresponding to the operated pad operator 30 in the pad operator management map for the current bank. Is stored with information indicating that no waveform data is assigned.

When the processing in step S912 is completed, the flow advances to step S914, in which the operated pad operator 30 is turned off, the clipboard operator 32 is turned on, and the clipboard operation (performance mode) processing is ended. I do.

On the other hand, if it is determined in step S 910 that waveform data has been assigned to the clip board operator 32, “overwrite?” Is displayed on the lower display screen 48 b of the LCD 48, and the clip
The board operator 32 blinks (step S916),
The "overwrite?" Display asks the user whether the waveform data already assigned to the clipboard operator 32 can be deleted and new waveform data can be assigned.

Then, the flow advances to step S918, where Ye
It is determined whether or not the s operation element 42 has been operated.

If it is determined in step S918 that the Yes operator 42 has been operated, "overwrite?"
The display is erased, and the process proceeds to step S912, in which the waveform data assigned to the pad operator 30 operated in the current bank is assigned to the clipboard operator 32.

On the other hand, in step S918, Yes
If it is not determined that the operation element 42 has been operated,
Proceeding to step S920, it is determined whether the No operator 44 has been operated.

At step S920, No operation element 4
4 is operated, the "overwrite?" Display is erased, and the clipboard operator 32, which has been turned on and off in step S916, is returned to the lighted state. ) End the processing.

On the other hand, if it is not determined in step S920 that the No operator 44 has been operated, the process returns to step S918.

Therefore, when the waveform data assigned to a certain pad operator 30 is assigned to another pad operator 30, the following operation may be performed.

Procedure 1: The clip board operator 32 is operated while the pad operator 30 (lit) of the waveform data transfer source is being operated.

By the operation of this procedure 1, the pad operator 3
The waveform data assigned to 0 is moved to the clipboard operator 32. At this time, the pad operator 30 is turned off, and the clipboard operator 32 is turned on. This means that no waveform data is assigned to the pad operator 30 and that the clip
This shows that waveform data has been assigned to the board operator 32.

When the clip board operator 32 is operated in this state, the waveform data transferred to the clip board operator 32 is reproduced.

When the operation of the procedure 1 is performed in a state where the clip board operator 32 is lit and some waveform data has already been assigned to the clip board operator 32, "overwrite?" The message “Overwrite?” Means “Will the waveform data currently assigned to the clipboard operator 32 be overwritten and overwritten?” Is displayed, and the clipboard operator 32 is displayed. Flashes.

Here, if overwriting is allowed, Y
The ES operator 42 is operated. Then, the YES operator 42
Is operated, the waveform data is transferred from the pad operator 30 to the clipboard operator 32.

If it is not desired to overwrite, the NO operator 44 is operated. When the NO operator 44 is operated, the process is interrupted and the movement of the waveform data is not performed. Step 2: The pad operator 30 to which the waveform data is transferred is operated while operating the clip board operator 32.

By the operation of the procedure 2, the waveform data assigned to the clipboard operator 32 is transferred to the operated pad operator 30. At this time, the clip board operator 32 is turned off, and the operated pad operator 30 is turned on. This indicates that the waveform data has not been assigned to the clipboard operator 32 and the waveform data has been assigned to the operated pad operator 30.

In this state, the pad operator 30
Is operated, the waveform data transferred to the pad operator 30 is reproduced.

When the operation of the procedure 2 is performed in a state where the pad operator 30 of the transfer destination is illuminated and some waveform data has already been assigned to the pad operator 30, "overwrite?"("Overwrite?" Means "Will the waveform data currently assigned to the pad operator 30 be overwritten and overwritten?") Is displayed, and the pad operator 30 is displayed.
Flashes.

Here, if overwriting is allowed, Y
The ES operator 42 is operated. Then, the YES operator 42
Is operated, the waveform data is transferred from the clipboard operator 32 to the pad operator 30.

If it is not desired to overwrite, the NO operator 44 is operated. When the NO operator 44 is operated, the process is interrupted and the movement of the waveform data is not performed. Note that the operations in Procedure 1 and Procedure 2 described above can be performed between different banks. That is, the operation of the above procedure 1 is performed in a state where a certain bank is selected, and then the operation of the procedure 2 is performed by switching the bank. By such an operation, the pad operator 3 with the pad number 1 in a certain bank
The waveform data assigned to 0 can be reassigned to the pad operator 30 of pad number 1 and the pad operator 30 of pad number 5 in another bank.

Further, by utilizing the above-described waveform data transfer function, it is possible to delete waveform data assigned to an arbitrary pad. That is, the operation of operating the clipboard operator 32 while operating the pad operator 30 whose waveform data is to be erased is repeated for the pad operator 30 whose waveform data is to be erased. At this time, the operated pad operator 30 is in a state where no waveform data is assigned, and goes out, and the clipboard operator 32 is assigned the waveform data assigned to the last operated pad operator 30. Lights up.

Next, the processing when the delete operator 38 is operated in the performance mode will be described with reference to the flowchart of the delete operation (performance mode) processing shown in FIG.

That is, when the delete operation element 38 is operated in the performance mode, the processing shown in the flowchart of the delete operation (performance mode) processing in FIG. 10 is executed.

In the flowchart of the delete operation (performance mode) processing, first, in step S1002, it is determined whether or not the pad operator 30 is being operated.

If it is determined in step S1002 that the pad operator 30 is being operated, that is, if the delete operator 38 is operated while the pad operator 30 is being operated, the flow advances to step S1004 to change the current bank. The assignment of the waveform data assigned to the pad operator 30 being operated in is released. Specifically, information indicating that waveform data is not assigned is stored in a column corresponding to the pad operator 30 being operated in the pad operator management map for the current bank.

At this time, the currently operated pad operator 3
The waveform data assigned to 0 may be deleted, and the unstored portion of the waveform data storage area may be expanded.

Alternatively, when the delete operator 38 is operated, only the column indicating whether or not the waveform data of the pad operator management map is allocated is rewritten, and the pad operator management map is designated by a predetermined operation instruction. For example, the previously assigned waveform data may be deleted from the pad operator 30 in which information indicating that no waveform data is assigned is stored.

When the processing in step S1004 ends,
Proceeding to step S1006, based on the stored contents of the changed pad control management map, the pad control 30 to which the waveform data is allocated in the current bank is turned on, and the pad to which the waveform data is not allocated in the current bank. The operator 30 is turned off, and the delete operation (performance mode) process is terminated.

On the other hand, if it is determined in step S1002 that the pad operator 30 is not being operated, the delete operation (performance mode) processing is terminated.

Next, the processing when the staff operator 40 is operated in the performance mode will be described with reference to the flowchart of the staff operation (stuff mode) processing shown in FIG.

That is, when the stuff operator 40 is operated in the performance mode, the mode becomes the stuff mode, and the setting screen for the range of banks (the first bank and the last bank) in which the reassignment of the waveform data to the pad operators 30 is performed. . In this screen, the display screen 48a at the upper stage of the LCD 48
"Stuff mode" is displayed, and "First bank: last bank" is displayed on the lower display screen 48b. Numeric key 46
In the first operation, the bank number of the first bank is input, and in the next operation, the bank number of the last bank is input.

When the stuff operator 40 is operated again, the stuff operation (stuff mode) process shown in FIG. 11 is performed. In this stuff operation (stuff mode) process, the ten key 46 is set to the bank number bank. The set start bank number start is set (step S1102), and “1” is set to the pad number pad (step S1104).

Then, the flow advances to step S1106 to refer to the pad controller management map and to determine whether waveform data is assigned to the pad controller 30 of the pad number pad of the bank of the bank number bank (whether or not an empty pad). Judge).

In step S1106, the pad operator 3 of the pad number pad of the bank of the bank number bank
If it is determined that waveform data has not been assigned to 0, the process proceeds to step S1108, where bank number b
The stored contents of the pad operator management map relating to the pad operator 30 whose pad number is larger than pad in the bank of the bank “an” are moved to the area of the pad operator 30 whose pad number is smaller by one, and then the bank one larger than the bank number bank. Pad operator 30 of pad number 1 in the bank of the number
The stored contents of the pad operator control map relating to the pad operator 16 are moved to the area of the pad operator of the pad number 16 of the bank number bank number, and the stored contents of the pad operator control map are stored in the bank of the bank number one larger than the bank number bank. The process moves to the area of the pad operator having the smaller pad number, and the same processing is repeated until the last bank.

It should be noted that, regarding the pad operator 30 of the pad number 16 in the last bank, since there is no stored content of the pad operator management map to be transferred, it indicates that no waveform data is allocated to the pad operator management map. Store the information.

The same processing is performed by setting the pad number pad to “1”.
Until the processing reaches "6", that is, until the processing is performed on the pad operator with the pad number 16, the above processing is repeated while incrementing the pad number pad by "1" (step S1110 → step S1112 → step S1).
104).

When the processing for the pad operator of pad number 16 is completed, the flow advances to step S1106, and
The above-described processing is repeated while incrementing the bank number bank by “1” until the bank number bank becomes the end bank number end, that is, until processing is performed on the end bank (step S1114 → step S1).
1116 → step S1104).

When the processing for the last bank is completed, the flow advances to step S1118 to light the pad operator 30 to which the waveform data is assigned in the current bank based on the stored contents of the changed pad operator management map. At the same time, the pad operator 30 to which the waveform data is not assigned in the current bank is turned off, and the stuff operation (stuff mode) processing is ended.

Therefore, by the above-described stuff operation (stuff mode) processing, the pad operators 30 to which the waveform data are assigned are sequentially packed and arranged in the order of the smaller pad number and the smaller bank number. Will be.

For example, by using the clip board operator 32 and the delete operator 38, if the pad operators 30 to which the waveform data are not allocated are present everywhere in various banks, when performing, May be confused. Specifically, pad number 1, pad number 3, pad number 7, pad number 9,
Pad No. 14, Pad No. 15 and Pad No. 1
In the case where the waveform data is assigned only to each of the pad operators 30 of No. 6, the pad operators 30 to which the waveform data is assigned may be discretely present, and thus may be confused during the performance.

However, according to the above-described staff operation (stuff mode) processing, each pad operation of pad number 1, pad number 3, pad number 7, pad number 9, pad number 14, pad number 15, and pad number 16 is performed. Since the waveform data is reassigned so that the assignment of the waveform data to the child 30 is continuously assigned to the pad operators 30 of the pad numbers 1 to 7, the performance is facilitated.

In the bank of bank number 1, waveform data is assigned only to five pad operators 30, and in the bank of bank number 7, seven pad operators 30 are assigned.
When waveform data is assigned only to these two banks, it is necessary to switch banks when performing using the waveform data of these two banks, which makes the performance operation very complicated.

However, by performing the above-described stuff operation (stuff mode) processing, if these 12 waveform data items are gathered into the bank of bank number 1, the performance can be performed without switching banks, and the performance operation can be performed. Extremely simplified. Further, in this case, all the banks of bank number 2 are pad operators (empty pads) 30 to which no waveform data is assigned, so that new waveform data can be sampled and assigned here, and the waveform data can be assigned. It is easier to organize.

Next, the processing when the bank switching operator 34 is operated in the performance mode will be described with reference to the flowchart of the bank switching (performance mode) processing shown in FIG.

That is, when the bank switching operator 34 is operated in the performance mode, the processing shown in the flowchart of the bank switching (performance mode) processing in FIG. 12 is executed.

In the flowchart of the bank switching (performance mode) process, first, in step S1202, the bank is switched according to the operation of the bank switching operator. As a result, the waveform data corresponding to the new bank is assigned to each pad operator 30.

When the processing in step S1202 ends,
Proceeding to step S1204, based on the stored contents of the pad operator control map, the pad operator 30 to which the waveform data is assigned in the new bank is turned on, and the pad operation to which the waveform data is not assigned in the new bank is performed. The child 30 is turned off, and this bank switching (performance mode) processing is terminated.

As a result, each pad operator 30 is displayed according to the assignment state of the waveform data, and the user can identify at a glance which pad the waveform data is assigned to.

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

(1) In the above-described embodiment, when the waveform data is transferred from the clipboard operator 32 to the pad operator 30, the state where no waveform data is assigned to the clipboard operator 32 is determined. However, the present invention is not limited to this, and a mode in which the clipboard operator 32 leaves waveform data may be provided. In addition, the pad operator 30 and the clip board operator 32

(2) In the above-described embodiment, one pad operator 30 is provided for the clip board operator 32.
Although only the waveform data of one pad operator 30 is allocated, the present invention is not limited to this, and a plurality of waveform data may be allocated from a plurality of pad operators 30. In this case, an identification code such as a name or a number is assigned to the plurality of waveform data, the identification code is displayed, any one of the waveform data is arbitrarily selected, and the selected waveform data is clipped /
Playback is performed according to the operation of the board operator 32, or the selected waveform data is transferred from the clipboard operator 32 to the pad operator 30.

(3) In the above embodiment, only the waveform data is assigned to the pad operator 30. However, the present invention is not limited to this, and the waveform data may be reproduced in addition to the waveform data. May also be assigned. Or, instead of assigning waveform data,
A tone control parameter defining the tone to be generated may be assigned.

(4) In the above-described embodiment, when the stuff operation (stuff mode) process is executed by operating the stuff operator 40, the stuff process is performed collectively for the designated range of banks. (Waveform data in the following bank is moved to the preceding bank.) However, the present invention is not limited to this, and a mode in which stuffing is performed independently in each bank is provided. Good.

(5) In the above embodiment, each pad operator 30 is self-illuminated. However, the present invention is not limited to this, and the state of assignment of waveform data to each pad operator 30 can be displayed. If so, it is a matter of course that other forms may be used. For example, a display may be provided near each pad operator 30.

(6) In the above-described embodiment, the storage area for the pad operator control map and the clipboard operator 32 stores the waveform data storage position as a pointer to the waveform data instead of the waveform data itself. , But without being limited to this,
The waveform data itself may be stored.

(7) Staff operation (stuff mode)
The processing may be performed by a processing method other than that described in the above embodiment. Hereinafter, processing methods other than those described in the above embodiment will be described.

First, a processing method will be described.
In this processing method, a work map having the same configuration as one bank of the pad operator management map shown in FIG. 3 is provided in advance. Then, first, it is determined whether or not waveform data has been assigned to the first (first) pad operator 30 with respect to the first bank in which the assignment of the waveform data to the pad operator 30 is to be performed again. If assigned, the contents of the pad operator management map of the pad operator 30 are added to the head of the work map (1).
After copying to the area of the (No.) pad operator 30, a similar determination is made for the next (No. 2) pad operator 30.

If no waveform data is assigned to the first (first) pad operator 30, the same judgment is made for the next (second) pad operator 30 without performing the above-described copying.

If waveform data is assigned to the next (second) pad operator 30, the contents of the pad operator management map of that pad operator 30 are copied to the pad operator 30 of the work map that has not been copied yet. Of the first pad operator 30 (if the copy is performed with respect to the first pad operator 30, it is the area of the second pad operator 30; the copy must be performed with respect to the first pad operator 30). For example, the area is the area of the first pad operator 30), and the same determination is made for the next (third) pad operator 30.

If the waveform data is not assigned to the next (second) pad operator 30, the above-mentioned (third) pad operator 30 is skipped without copying.
Is determined in the same manner.

The same processing as described above is performed for the third, fourth, fifth,..., Pad operators 30.

The above processing is repeated, and when the processing for the first bank is completed, the same processing is performed for the next bank. Then, when copying is performed for all the pad operator 30 areas of the work map, the contents of the work map are copied to the first bank area where the assignment of the pad operator management map is redone.

Subsequently, the same processing is performed from the pad operator 30 following the pad operator 30 that has performed the above-described processing.
Again, when copying is performed for all the pad operator 30 areas of the work map, this time, the bank next to the bank copied so far in the pad operator management map (in this description, next to the first bank) Is copied to the area indicated by).

Thereafter, the processing is repeated in the same manner, and when the processing relating to the last bank for performing the redistribution is completed, the contents of the work map at that time are copied to the next bank of the pad operator management map. Between the first bank and the last bank to re-assign the pad controller management map.
The area of the pad operator 30 that has not yet been copied from the work map is cleared, and a state is shown indicating that waveform data has not been assigned to the pad operator 30 in that area.

It should be noted that even if the work map has a size other than one bank, the same processing can be performed.

Further, another processing method will be described. In this processing method, first, from the first pad operator 30 of the first bank for performing the reassignment,
The pad operator 30 to which the waveform data is assigned is searched for in ascending order of the pad number. When the pad operator 30 to which the waveform data is assigned is found, the pad operator management map of the pad operator 30 is stored. The contents are copied to the area of the first pad operator 30 in the first bank where the assignment of the pad operator management map is to be redone.

Next, the pad operator 30 that was just found
A similar search is performed from the pad operator of the next pad number, and the pad operator 30 to which the waveform data is assigned
Is found, the stored contents of the pad operator management map of the pad operator 30 are next to the first bank in which the assignment of the pad operator management map is re-allocated (the second bank in this description). Copy to the area of the pad operator 30.

In the same manner, the processing is sequentially performed on the next pad operator 30 and then on the next pad operator 30 in the same manner. When the processing for the pad operator 30 of the first bank is completed, the same processing is performed for the pad operator 30 of the next bank. When copying to the area of all pad operators 30 in the first bank of the pad operator management map is completed in this way, copying is performed to the area of pad operators 30 in the next bank.

Then, the same processing is repeated up to the last pad operator 30 in the last bank where the assignment is redone. Finally, between the area from the first pad operator 30 of the first bank to the last pad operator 30 of the last bank where the assignment of the pad operator management map is re-executed, the area which has not been copied yet is determined. The storage contents are cleared, and a state is shown indicating that waveform data has not been assigned to the pad operator 30 in that area.

It is to be noted that various processing methods other than the above-described processing methods can be employed. In short, the waveform data allocated to the pad operator 30 in each bank to be reallocated is stored in the bank. , And the order of the pad operators 30 to which the waveform data is assigned, from the first pad operator 30 of the first bank to be reassigned to the next pad operator 30, the assignment of the pad data is further performed. Pad operator 3 at the beginning of the bank to be redone after that
It goes without saying that any processing method may be adopted as long as it can be re-assigned in order from 0 to the subsequent pad operator 30.

(8) In the above embodiment, the bank for performing the stuff processing is specified. However, the stuff processing may be performed for all the banks at once.

(9) In the above-described embodiment, when a bank to be subjected to the stuff process is designated, a bank within a predetermined range is designated by designating a head bank and a tail bank. Without being limited to
Banks for performing stuff processing may be individually specified.
