[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic musical instrument, and more specifically, performance data stored in an external storage means is transferred from the external storage means to an internal storage means, or stored in the internal storage means. The present invention relates to an electronic musical instrument that can transfer data from the internal storage means to an external storage means for storage.
[0002]
In the present specification, “transferring performance data stored in the external storage means from the external storage means to the internal storage means” is referred to as “load” as appropriate. “Performance data stored in the means is transferred from the internal storage means to the external storage means for storage” will be appropriately referred to as “save”.
[0003]
[Prior art]
Conventionally, performance data stored in an external storage device such as a hard disk is selected as external storage means, and the selected performance data is selected from the external storage device as internal storage means, such as a random access memory (RAM). There is known an electronic musical instrument that is read into the internal storage area and generates musical sounds based on performance data read into the internal storage area.
[0004]
By the way, in the conventional electronic musical instrument as described above, desired waveform data is selected from a plurality of waveform data stored in an external storage device such as a hard disk as external storage means as a plurality of performance data. (The waveform data to be selected may be singular or plural.) When loading the selected waveform data from the external storage device to an internal storage area such as a RAM as an internal storage means of the electronic musical instrument, be sure to It was designed to load all selected waveform data.
[0005]
Similarly, in a conventional electronic musical instrument, desired waveform data is selected from a plurality of waveform data stored in an internal storage area such as a RAM as internal performance as performance data (the waveform data to be selected is When the selected waveform data is saved from the internal storage area to an external storage device such as a hard disk as external storage means, all the selected waveform data must be saved. It was made to save.
[0006]
For this reason, the conventional electronic musical instrument has a problem that it takes time to process and save performance data.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems of the prior art. The object of the present invention is to transfer performance data stored in the external storage means from the external storage means to the internal storage means. When transferring and storing, that is, when loading performance data from the external storage means to the internal storage means, or when transferring performance data stored in the internal storage means from the internal storage means to the external storage means That is, when saving performance data from the internal storage means to the external storage means, an electronic musical instrument that can perform the processing at a high speed to shorten the time required for the processing is provided. It is.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention transfers performance data stored in the external storage means from the external storage means to the internal storage means, that is, stores performance data from the external storage means to the internal storage means. In order to reduce the time required for the loading process, it is checked whether or not the same performance data has already been loaded. is there.
[0009]
More specifically, in the present invention, when it is instructed to load performance data from the external storage means to the internal storage means (the performance data instructed to be loaded may be singular or plural). It is checked whether or not the performance data instructed to be loaded is already loaded, and if there is already loaded performance data, the already loaded performance data is not loaded and is not loaded. By loading only the performance data, the time required for the loading process is shortened.
[0010]
Even if the performance data is already loaded from the external storage means to the internal storage means, the performance data already loaded to the internal storage means is changed from the loaded state by processing such as editing. If the contents of the performance data stored in the external storage means and the contents of the performance data stored in the internal storage means are different, the performance data stored in the external storage means is stored in the internal storage means. By loading again, consistency between the contents of the performance data stored in the internal storage means and the contents of the performance data stored in the external storage means is maintained.
[0011]
Further, the present invention transfers the performance data stored in the internal storage means from the internal storage means to the external storage means, that is, when saving performance data from the internal storage means to the external storage means. It is determined whether or not the same performance data has already been saved, and the performance data that has already been saved is not saved again, thereby shortening the time required for the save process.
[0012]
More specifically, in the present invention, when the performance data is instructed to be saved from the internal storage means to the external storage means (the performance data instructed to be saved may be singular or plural). It is checked whether or not the performance data instructed to be saved has already been saved, and if there is already saved performance data, the already saved performance data is not saved but not saved. By saving only the performance data, the time required for the save process is shortened.
[0013]
Even if the performance data is already saved from the internal storage means to the external storage means, the performance data stored in the internal storage means corresponding to the performance data already saved in the external storage means is edited. When the processing changes the state at the time of saving and the contents of the performance data stored in the external storage means differ from the contents of the performance data stored in the internal storage means, the internal storage means By saving the performance data stored in the memory in the external storage means again, the contents of the performance data stored in the internal storage means and the contents of the performance data stored in the external storage means are maintained consistent. It is to make.
[0014]
That is, the invention according to claim 1 of the present invention is stored in the external storage means.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of an electronic musical instrument according to the present invention will be described in detail with reference to the accompanying drawings.
[0017]
FIG. 1 is a block diagram of an electronic musical instrument according to an example of an embodiment of the present invention.
[0018]

[0019]
The electronic musical instrument is connected to an external storage device 200 such as a hard disk as external storage means. The external storage device 200 stores a plurality of waveform data as a plurality of performance data. .
[0020]
In addition, the CPU 10 of the electronic musical instrument stores a program memory (a program memory that stores programs executed by the CPU 10 for controlling operations as shown in flowcharts described later) via the bus 12. , And a working memory (working memory as a working area) in which various buffers and registers (to be described later) necessary for execution of the program by the CPU 10 are set. The memory is composed of a RAM.) 16. The waveform data can be loaded and stored from the external storage device 200, and the stored waveform data can be saved and stored in the external storage device 200. Waveform memory as internal storage means (note that waveform memory is RAM 18), an operator group 20 composed of various operators disposed on the operation panel 100 described later, a display device 22 disposed on the operation panel 100 described later, and an external MIDI device. Are connected to a MIDI interface (MIDI I / F) 24 for communicating with each other.
[0021]
Note that a digital / analog converter (D / A) 26 is connected to the CPU 10. The D / A 26 converts the digital musical tone signal generated by the CPU 10 based on the waveform data stored in the waveform memory 18 into an analog musical tone signal and outputs it.
[0022]
The analog tone signal output from the D / A 26 includes an amplifier for amplifying the analog tone signal, a speaker for emitting the analog tone signal amplified by the amplifier as a tone in the space, and the like. The sound is emitted into the space as a musical sound through a sound system (not shown).
[0023]
The electronic musical instrument is also provided with a function of editing the waveform data stored in the waveform memory 18 (“editing” includes changing the pitch and tone color). The configuration for realizing the function of editing the waveform data described above can use a known technique. Therefore, in order to simplify the explanation and facilitate understanding of the present invention, the details thereof will be described. The detailed explanation is omitted.
[0024]
2 to 5 are explanatory diagrams of the configuration of the operation panel 100 in which various operators constituting the operator group 20 and the display device 22 are arranged.
[0025]
Here, the display device 22 includes a display screen 22a configured by, for example, a liquid crystal display (LCD), and various information as described later is displayed on the display screen 22a.
[0026]
Next, with reference to FIG. 2 to FIG. 5, an explanation will be given of the operation executed based on the operation of various operators constituting the operator group 20 and the content of information displayed on the display screen 22a in accordance with the operation. To do.
[0027]
First, various operators constituting the operator group 20 will be described. The operators related to the implementation of the present invention include a menu (MENU) switch 20a, an increment (INC) switch 20b, and a decrement (DEC). Switch 20c, Up (UP) switch 20d, Down (DOWN) switch 20e, Left (LEFT) switch 20f, Right (RIGHT) switch 20g, Exit (EXIT) switch 20h Enter switch 20i, function 1 (F1) switch 20j, function 2 (F2) switch 20k, function 3 (F3) switch 20l, and function 4 (F4) switch 20m are set. .
[0028]
Among the above-described operators, the increment switch 20b and the decrement switch 20c are operated when changing the value to be set, and the value is “1” every time the increment switch 20b is pressed. ”And the value decreases by“ 1 ”every time the decrement switch 20c is pressed once.
[0029]
Among the above-described operators, the up switch 20d, the down switch 20e, the left switch 20f, and the right switch 20g are operated when the cursor displayed on the display screen 22a of the display device 22 is moved. When the up switch 20d is pressed, the cursor is moved upward, when the down switch 20e is pressed, the cursor is moved downward, and when the left switch 20f is pressed, the cursor is moved to the left. When the switch 20g is pressed, the cursor is moved to the right.
[0030]
Here, on the display screen 22a of the display device 22 of FIG. 2, after the electronic musical instrument is turned on, a menu screen is displayed when the down switch 20e is pressed twice after the menu switch 20a is pressed. Yes. The display content of the display screen 22a indicates that the cursor is positioned on the display of “DISK Load menu” and “DISK Load menu” is selected.
[0031]
When the enter switch 20i is pressed in the state shown in FIG. 2, the display screen 22a of the display device 22 is in the state shown in FIG. The display content of the display screen 22a in FIG. 3 shows a selection screen of waveform data to be loaded.
[0032]
In the display screen 22a in FIG. 3, the “+” mark located on the left side is the name to which the “+” mark is attached (in the following, the name of the waveform data is appropriately referred to as “waveform data name”). ")" Is selected as an object to be loaded. That is, FIG. 3 shows a state where the waveform data with the waveform data name “Drum Kick 1” and the waveform data with the waveform data name “AC. Bass 1” are selected.
[0033]
Here, in order to select the waveform data to be loaded, the cursor (in FIG. 3, the cursor is represented by an “underline” positioned below the waveform data name) is located in the waveform data name of the desired waveform data. In this state, the enter switch 20i may be pushed. As a result, the waveform data to be loaded is selected, and a “+” mark is displayed on the left side of the waveform data name.
[0034]
In addition, when the enter switch 20i is pressed while the cursor is positioned on the waveform data name selected as the waveform data to be loaded, the selection as the waveform data to be loaded is canceled, and “+ The “” mark disappears.
[0035]
Further, when the F4 switch 20m is pressed in the state shown in FIG. 3, the display screen 22a of the display device 22 is in the state shown in FIG. The display content of the display screen 22a in FIG. 4 is the first among the selected waveform data of the sample in the waveform memory 18 when the waveform data selected as described above is sequentially loaded into the waveform memory 18. 4 shows a screen for instructing and setting a sample number (hereinafter referred to as “load destination sample number” as appropriate) of the first sample from which waveform data to be loaded is to be loaded.
[0036]
On the display screen 22a shown in FIG. 4, when the increment switch 20b is pressed, the value of the load destination sample number is increased by “1”, and when the decrement switch 20c is pressed, the value of the load destination sample number is only “1”. Will be reduced.
[0037]
The display screen 22a shown in FIG. 4 shows a state in which “001” is instructed and set as the value of the load destination sample number, and the sample number of the sample to be loaded in the waveform memory 18 is “1”.
[0038]
When the F4 switch 20m is pressed in the state shown in FIG. 4, in order to prepare for loading the selected waveform data, it is determined whether or not the waveform data selected as the load target has already been loaded into the waveform memory 18. Processing to check is performed. This process is executed as a waveform memory search process routine shown in the flowchart of FIG.
[0039]
Here, not all the waveform data selected as the load target is stored in the waveform memory 18 or all the waveform data selected as the load target is stored in the waveform memory 18. When all the waveform data stored in the waveform memory 18 has been edited and the content of the waveform data stored in the external storage device 200 is different from the content of the waveform data stored in the waveform memory 18. When the F4 switch 20m is pressed in the state shown in FIG. 4 described above, all of the waveform data selected as a load target is automatically loaded into the waveform memory 18 as it is (this load is a conventional technique). 10 is referred to as “normal load processing.” This normal load processing is described later with reference to FIG. Is executed as a normal loading process routine shown in the flow chart.).
[0040]
On the other hand, when at least one of the waveform data selected for loading is already loaded into the waveform memory 18 and the waveform data already loaded into the waveform memory 18 is not edited, It automatically changes to the state of the display screen 22a in FIG. The display content of the display screen 22a in FIG. 5 is a high-speed load process related to the implementation of the present invention (this “high-speed load process” will be described later. The high-speed load process is described later in the flowchart of FIG. It is executed as a load processing routine.) An instruction screen is shown.
[0041]
Then, the display screen 22a shown in FIG. 5 waits for an instruction as to whether or not to load at high speed. When the F4 switch 20m for designating “ALL” is pressed in this instruction waiting state, the load is selected. All of the selected waveform data is loaded into the waveform memory 18 (this loading is performed by the above-described normal loading process), while the F1 switch 20j designating “QUICK” is pressed while waiting for this instruction. If so, the high-speed load process described later is performed (the high-speed load process is executed as a high-speed load process routine shown in the flowchart of FIG. 11 described later).
[0042]
The waveform data names selected in the waveform data selection screen shown in FIG. 3 are stored in the selected order in the select array array table shown in FIG. 6 set in the working area 16. Will be.
[0043]
In this embodiment, the maximum number of waveform data that can be selected on the waveform data selection screen shown in FIG. 3 is set to “5”, and the select array array table has a maximum of five in the order of selection. The waveform data name is stored.
[0044]
In the example of the select array arrangement table shown in FIG. 6, “Piano 1” is stored as the waveform data name in order 0, “Piano 3” is stored as the waveform data name in order 1, and “Strings 1” is stored as the waveform data name, “Drum Kick 2” is stored as the waveform data name in order 3, and “AC. Bass 1” is stored as the waveform data name in order 4.
[0045]
FIG. 7 shows an example of the state of the waveform memory 18 before and after the high speed loading process, and the current state of the waveform memory 18 before the high speed loading process is shown on the left side in FIG. FIG. 7 shows the state of the waveform memory 18 after the high speed loading process on the right side.
[0046]
The example shown in FIG. 7 shows a case where the waveform data shown in the select array array table shown in FIG. 6 is selected as a load target. In the select array array table shown in FIG. Although data is selected as a load target, only one waveform data name “Drum Kick 2” is actually loaded in the high-speed load process described later.
[0047]
Next, referring to the flowcharts shown in FIGS. 8 and 10 to 12, the select array arrangement table shown in FIG. 6, the explanatory diagram of the state of the waveform memory shown in FIG. 7, and the waveform data arrangement table shown in FIG. The loading process in this electronic musical instrument will be described.
[0048]
In the waveform data array table shown in FIG. 9, in order to facilitate understanding of the present invention, the state of the waveform memory 18 before loading is shown in “Current waveform memory before high-speed loading processing” shown in FIG. FIG. 6 shows the case where the contents of the select array arrangement table shown in FIG.
[0049]
Note that the registers used in the processing of the above-described flowchart include those shown in (1) to (4) described below.
[0050]
(1) SelectArray
This is a register for storing the waveform data name selected as the waveform data to be loaded and stored in the select array array table.
[0051]
(2) Load Strategie_Load (Load Strategie_Load [j])
Waveform data to be loaded so as to know which waveform data is loaded into the jth sample ("j" is 0 and a positive integer) in the waveform memory 18, that is, the sample with the sample number j. A register that stores the name. Note that when “undefined” is stored in Load Strategie_Load, it indicates that the name of the waveform data to be loaded cannot be specified.
[0052]
(3) Load Strategie_Erase
This is a register that stores information indicating whether or not to delete the j-th sample ("j" is 0 and a positive integer) in the waveform memory 18, that is, the sample with the sample number j. When “true” is stored in LoadStrategy_Erase, the sample of the sample number is deleted, and when “false” is stored in LoadStrategy_Erase, the sample of the sample number is not deleted. Note that when “undefined” is stored in LoadStrategy_Erase, it indicates that it is not possible to specify whether or not to delete the sample of that sample number.
[0053]
(4) Load Strategy_Move (Load Strategy_Move [j])
The jth sample ("j" is a positive integer including 0) in the waveform memory 18, that is, a sample number j is a register storing information indicating whether or not the sample number j can be loaded by exchange. When “Undefined” is stored in LoadStrategy_Move, it indicates that it is not possible to specify whether or not the sample with the sample number can be loaded by exchange.
[0054]
First, referring to the flowchart of the waveform memory search process routine shown in FIG. 8, it is checked whether or not the waveform data to be loaded is already loaded in the waveform memory 18 and the waveform memory search process will be described.
[0055]
That is, the waveform memory search processing routine shown in FIG. 8 is started when the F4 switch 20m is pressed in the state shown in FIG. 4, and when this waveform memory search processing routine is started, the above-described FIG. The list of waveform data selected by the selection operation of the waveform data to be loaded described with reference to the display screen 22a shown in FIG. 4 is copied from SelectArray to LoadStrategy_Load (step S802).
[0056]
Next, the stored contents of the current waveform memory 18 starting from the load destination sample number set on the display screen 22a shown in FIG. 4 are compared with the stored contents of the SelectArray, and the samples not in the SelectArray are deleted from the waveform memory 18. Since it becomes a target, LoadStrategy_Erase is set to “true” (step S804).
[0057]
Then, the SelectArray and the entire stored contents of the current waveform memory 18 are examined. If the sample in the SelectArray exists in the waveform memory 18 and the waveform data of the sample has not been edited, LoadStrateg_Move is set to “true”. (Step S806), and the processing of this waveform memory search processing routine is terminated.
[0058]
In this electronic musical instrument, an edit flag is provided for each waveform data stored in the waveform memory 18, and if any editing is performed on the waveform data stored in the waveform memory 18, the edited waveform is displayed. Assume that the flag corresponding to the data is set. In the process of step S806, it is determined whether or not the waveform data has been edited according to the state of the edit flag.
[0059]
FIG. 9 shows the state of the array after the execution of the waveform memory search processing routine shown in FIG.
[0060]
Next, normal load processing for loading all selected waveform data will be described with reference to the flowchart of the normal load processing routine shown in FIG.
[0061]
That is, the normal load processing routine shown in FIG. 10 is started when the F4 switch 20m is pushed in the state shown in FIG. 4 or when the F4 switch 20m is pushed in the state shown in FIG. When the load processing routine is started, first, the sample waveform data in the waveform memory 18 is deleted from the load destination sample number set on the display screen 22a shown in FIG. 4 by the number of waveform data to be loaded (step S1002). ).
[0062]
Then, all the selected waveform data is loaded from the load destination sample number to the sample of the waveform memory 18, and this normal load processing routine is terminated.
[0063]
Therefore, all the selected waveform data is loaded into the waveform memory 18 by the processing of the normal load processing routine.
[0064]
Next, with reference to the flowchart of the high-speed load processing routine shown in FIG. 11, only the necessary waveform data is loaded without loading all the selected waveform data, and the high-speed load processing for speeding up the load processing is performed. explain.
[0065]
That is, the high-speed load processing routine shown in FIG. 11 is started when the F1 switch 20j is pressed in the state shown in FIG. 5. When this high-speed load processing routine is started, first, FIG. The waveform data is erased from the sample of the waveform memory 18 set to “true” based on the Load Strategie_Erase set in step S804 of the waveform memory search processing routine shown (step S1102).
[0066]
Then, the sample exchange process shown in the flowchart of FIG. 12 is performed as a sub-routine of this high-speed load process routine, and waveform data is exchanged between exchangeable samples (step S1104).
[0067]
Further, waveform data is loaded to the sample of the waveform memory 18 set to “false” based on LoadStrategy_Move (step S1106). At this time, if LoadStrategy_Erase is “false”, the waveform data is erased from the sample of the waveform memory 18 and then the waveform data is loaded.
[0068]
Then, when the process of step S1106 is finished, this high-speed load processing routine is finished.
[0069]
Next, the sample exchange process will be described with reference to the flowchart of the sample exchange process routine shown in FIG. In this sample exchange process, when Load Strategie_Move is “true”, the waveform data that is the same as the waveform data selected as the load target is searched from the sample of the current waveform memory 18, and the waveform data of the sample number of the searched sample is searched. And the waveform data of the sample number of the sample selected as the load target are exchanged.
[0070]
When this sample exchange processing routine is started, first, the load destination sample number is set to the processing variable j (step S1202).
[0071]
Next, regarding the processing shown in steps S1204 to S1212 to be described later, it is determined whether or not the waveform data selected as the load target has been repeated. If it is determined that the waveform data has been repeatedly selected, The sample exchange processing routine is terminated and the process returns to the high-speed loading processing routine. If it is determined that the selected waveform data has not been repeated, it is determined whether or not LoadStrategy_Move [j] is “true”. (Step S1206).
[0072]
Here, if it is determined that LoadStrateg_Move [j] is “true”, the sample number of the sample having the same waveform data name as that of LoadStrategy_Load [j] is set in the processing variable k (Step S1208). And the sample of sample number j are exchanged (step S1210).
[0073]
Then, the process variable j is incremented by “1”, the process returns to step S1204, and the subsequent processes are repeated.
[0074]
Therefore, all the selected waveform data is not loaded into the waveform memory 18 by the processing of the high-speed load processing routine, and the waveform data that has not been loaded into the waveform memory 18 among all the selected waveform data. In addition, since only the edited waveform data is loaded even if already loaded in the waveform memory 18, the loading process can be performed at high speed, and the time required for the loading process is shortened. Will be able to.
[0075]
Next, waveform data saving will be described. The waveform data saving process may be the same as the waveform data loading process described above.
[0076]
That is, after the electronic musical instrument is turned on, after pressing the menu switch 20a, the down switch 20e is pressed three times, and the cursor is positioned on the display of “DISK Save menu” in the menu screen in FIG. When the enter switch 20i is pressed, the display screen 22a of the display device 22 is in the state shown in FIG. The display content of the display screen 22a in FIG. 13 shows a selection screen of waveform data to be saved.
[0077]
Then, on the display screen 22a in FIG. 13, the waveform data having the waveform data name with the “+” mark located on the left side is selected as the save target, as in the case of the load shown in FIG. It shows that. That is, FIG. 13 shows a state where the waveform data with the waveform data name “Piano 1” and the waveform data with the waveform data name “Strings 1” are selected.
[0078]
Here, in order to select the waveform data to be saved, as in the case of selecting the waveform data to be loaded, the cursor is placed on the waveform data name of the desired waveform data (in FIG. 13, the cursor is positioned below the waveform data name). In this state, the enter switch 20i may be pressed. As a result, the waveform data to be saved is selected.
[0079]
If the enter switch 20i is pressed while the cursor is positioned on the waveform data name selected as the waveform data to be saved, the selection as the waveform data to be saved is cancelled.
[0080]
Further, as in the case of loading, when the F4 switch 20m is pressed in the state shown in FIG. 13, the waveform data selected as the save target is already stored in the external storage device in preparation for saving the selected waveform data. Check whether it is saved in 200 or not. That is, when saving is instructed, it is checked whether there is already saved waveform data.
[0081]
Here, all the waveform data selected as the save target are not stored in the external storage device 200 (that is, there is no waveform data already saved when the save is instructed). ) Or, even if all the waveform data selected as the save target is stored in the external storage device 200, all the waveform data stored in the waveform memory 18 is edited, and the external storage device 200 If the contents of the waveform data stored in the waveform memory 18 are different from the contents of the waveform data stored in the waveform memory 18, when the F4 switch 20m is pressed in the state shown in FIG. All of the selected waveform data is automatically saved in the external storage device 200 as it is (this save is performed in the conventional technique). And a similar process, appropriately referred to as "normal save process".).
[0082]
On the other hand, the waveform data corresponding to the waveform data already saved in the external storage device 200 is saved in the external storage device 200 even in one of the waveform data selected as the save target. When the waveform data stored in the memory 18 is not edited, the state automatically changes to the state of the display screen 22a similar to that in FIG.
[0083]
In this state, an instruction whether to perform a high-speed save process related to the implementation of the present invention (“high-speed save process” will be described later) is awaited. In this instruction wait state, the F4 switch 20m When pressed, all the waveform data selected as the save target is saved in the external storage device 200 (this save is normally performed by the save process), while F1 in the state of waiting for this instruction. When the switch 20j is pressed, a high-speed save process described later is performed.
[0084]
Next, the saving process in the electronic musical instrument will be described with reference to the flowcharts shown in FIGS.
[0085]
It should be noted that since a known technique can be applied to the normal save process, a detailed description thereof will be omitted in order to simplify the description and facilitate understanding of the present invention.
[0086]
Note that the registers used in the processing of the flowcharts shown in FIGS. 14 to 15 are those described in (1) described below.
[0087]
(1) SaveStrategy
This register stores information indicating whether or not saving is necessary.
[0088]
First, referring to the flowchart of the external storage device search processing routine shown in FIG. 14, processing for searching for waveform data that needs to be saved is performed.
[0089]
That is, the external storage device search processing routine shown in FIG. 14 is started when the F4 switch 20m is pressed in the state shown in FIG. If the waveform data selected by the waveform data selection operation is not stored in the external storage device 200, or if it has been edited even though it is stored in the external storage device 200, the waveform data The corresponding save strategy is set to “true”, and the save strategy corresponding to the waveform data that is not so is set to “false” (step S1402), and this external storage device search processing routine is terminated.
[0090]
Next, referring to the flowchart of the high-speed save processing routine shown in FIG. 15, the high-speed save process for saving only the necessary waveform data without saving all the selected waveform data and speeding up the save process. explain.
[0091]
That is, the high-speed save processing routine shown in FIG. 15 is started when the F1 switch 20j is pressed in the same state as in FIG. 5. When this high-speed save processing routine is started, first, FIG. Only the waveform data set to “true” is saved in the external storage device 200 based on the save strategy set in step 1402 of the external storage device search processing routine shown in FIG.
[0092]
Then, the edit flag corresponding to the waveform data saved in the external storage device 200 is cleared by the processing in step S1502 described above (step S1504), and this high-speed save processing routine is terminated.
[0093]
Therefore, all the selected waveform data is not saved in the external storage device 200 by the processing of the high-speed save processing routine, and is not already saved in the external storage device 200 among all the selected waveform data. Since only the edited waveform data is saved even if it is already saved in the external storage device 200, the saving process can be performed at high speed, and the time required for the saving process is saved. Can be shortened.
[0094]
The embodiment described above may be modified as shown in the following (1) to (3).
[0095]
(1) In the above-described embodiment, the electronic musical instrument that performs both the high-speed load process and the high-speed save process has been described. However, the present invention is not limited to this, and the high-speed load process and the high-speed save process are not limited thereto. Only one of them may be performed.
[0096]
(2) In the above-described embodiment, the maximum number of waveform data that can be selected on the waveform data selection screen shown in FIG. 3 is set to “5”, and the maximum number of select array arrangement tables is five in the order of selection. Although the waveform data names are stored, the present invention is not limited to this. Of course, the maximum number of waveform data that can be selected on the waveform data selection screen shown in FIG. The select array array table may store up to an arbitrary number of waveform data names in the order of selection.
[0097]
(3) You may make it combine the above-mentioned embodiment and the modification shown to said (1) thru | or (2) suitably.
[0098]
【The invention's effect】
Since the present invention is configured as described above, the performance data stored in the external storage means is transferred from the external storage means to the internal storage means, that is, the performance data is stored from the external storage means. When loading the performance data stored in the internal storage means or transferring the performance data stored in the internal storage means from the internal storage means to the external storage means, that is, saving the performance data from the internal storage means to the external storage means. At that time, it is possible to perform these processes at a high speed, and an excellent effect is obtained that the time required for the processes can be shortened.
