In the parameter editing apparatus for an electronic musical instrument according to the present invention, a plurality of parameters are divided and displayed on a plurality of pages, and the displayed parameters can be edited (edited) while the displayed parameters are being displayed. After displaying a certain page (first page) and editing the parameter (first parameter) displayed on the page, the page is changed to (second page) in order to edit the next parameter (second parameter). When switching, the page information storage means stores the information of the first page. When displaying and referencing or editing the first parameter again after the second parameter has been edited, the first page whose information is stored in the page information storage means is called using the calling means, so that the first page is promptly read. Is displayed according to the information. Information stored in the page information storage means, the position of the cursor in the page number and the display switching time point corresponding to the position of that page, information including such features switching state of the function switch. As a result, these contents are reproduced as they are when the page is called.

[0008] This makes it easy to switch pages during editing. When the second page is changed to the first page by the above-mentioned method, the information on the second page is stored in the page information storage means, so that the second page is called when the calling means is operated next time. be able to.

FIG. 1 is a block diagram of an electronic musical instrument to which the present invention is applied. In this electronic musical instrument, waveform data for synthesizing a tone signal is stored in a tone synthesis circuit 19, and when the keyboard 18 is operated, the tone synthesis circuit 19 reads out predetermined waveform data to synthesize a tone signal. . In the edit mode, parameters for editing the waveform data are displayed on the display 16 (see FIG. 2). The user can edit (edit) the value of the parameter by operating the switch group 14. Since the parameters are numerous, they are classified into a plurality of pages as shown in FIGS. 9B to 9D according to their types, and are displayed for each page.

A ROM 11, a RAM 12, a switch interface 13, a display interface 15, a keyboard interface 17, and a musical tone synthesizing circuit 19 are connected to a CPU 10, which is a control device, via a bus.
The ROM 11 stores a control program as shown in the flowcharts of FIGS. 4 to 7, the tree structure of FIG. 8, the image data of FIG. 9, and the like. In the RAM 12, a storage area for the above parameters, a page history buffer shown in FIG. 3, and an area for storing data generated during performance are set. Also, the switch interface 13
Is connected to a switch group 14, a display interface 15 is connected to a display 16, and a keyboard interface 17 is connected to a keyboard 18. Keyboard 1
Reference numeral 8 denotes a performance keyboard of about five octaves.

FIG. 2 is a diagram showing an operation panel including the switch group 14 and the display 16. The display 16 is an LCD matrix display. In the edit mode, a screen of a plurality of pages as shown in FIG.

The switch group 14 includes a HISTORY switch 20, a function switch group 21, a shift switch 22, and an edit switch group 23. The edit switch group 23 includes a numeric keypad and up / down / left / right switches. The HISTORY switch 20 is a Next (next) switch 20a, Previou
s (front) switch 20b. The functions of these key switches will be described later. The function switch group 21 includes eight switches 21-1 to 21-8 provided along the lower side of the display 16.
A unique function is assigned to each of these switches 21-1 to 21-8 for each page, and the function is displayed at the lower part of the display 16 (see FIG. 9). If there are many functions to be executed on the page, the switch 21
In some cases, two functions are assigned to some or all of -1 to 21-8. In this case, by turning on the shift switch 22, the switches 21-1 to 21-1 are turned on.
The function assigned to 21-8 can be switched.

FIG. 3 is a diagram showing a page history buffer set in the RAM 12. The page history buffer is a buffer for storing data (page information) relating to pages for which parameters have been edited over the past 20 pages, and has a recording pointer and a display pointer associated therewith. The page information storage area includes a page number and an edit information storage area. The recording pointer is a pointer that points to the latest record, that is, the buffer area in which the page information of the page displayed immediately before is stored. The display pointer is a pointer that indicates which page is being displayed when a page is displayed by going back through the records in the page history buffer. The page number is a numerical value shown before the page name in FIG. 8, and the number of digits indicates the depth of the hierarchy. The editing information includes information relating to various states necessary for displaying the page, such as a cursor position at the time of switching pages and a state of a shift switch.

When a page is displayed, its image data and parameter values are stored in ROM 11 and RAM 12.
, And setting various states such as the position of the cursor to a predetermined state constitutes a page screen. At the time of normal page switching, various states are set to standard values (cursor = upper left corner, function switch = unshift). When a page is switched based on the page history buffer, various states are determined based on page information of the page history buffer. Is set.

Here, in the edit mode, the user
When the up / down / left / right switch is turned on, the displayed edit page shifts by one page. That is, when the up / down switch is turned on, the page hierarchy shifts up or down by one. When the left / right switch is turned on, the page moves one page back and forth in the same hierarchy. When a page number is input using the numeric keypad, the display jumps to an edit page identified by the page number. For example, when "42" is input, an edit page of "System Utility" is displayed (see FIG. 9). The above-described page switching corresponds to the above-described normal page switching.
When the page is switched by such an operation after the parameter is edited, the page information of the page is written to the page history buffer.

On the other hand, in the edit mode, the Previo
When the us switch 20b is repeatedly turned on, the position of the display pointer in the page history buffer sequentially moves upward from the same buffer area as the recording pointer, and the page whose parameters have been edited in the past is displayed retrospectively. When the Next switch 20a is turned on, the previously displayed page is sent next. When the HISTORY switch 20 (Next switch 20a, Previous switch 20b) is turned on at the same time, a list of page names stored in the page history buffer is displayed on the display 16 (see FIG. 9A).

The operation of the electronic musical instrument will be described with reference to the flowcharts of FIGS.

FIG. 4 shows a main routine. When the power of the electronic musical instrument is turned on, an initial setting operation such as resetting a register is executed (n1). Thereby, the electronic musical instrument becomes operable, and thereafter, the edit processing (n2) and the sound generation processing (n3) are repeatedly executed.

FIG. 5 is a flowchart showing the operation of the edit processing. First, it is scanned whether or not the panel switch has been operated (n10). If there is no operation event, since no editing has been performed, the process directly returns (n11). If there is an operation, it is determined whether the operation content is an operation related to page switching (n12), an operation of the function switch 21 (n13), an operation of the HISTORY switch 20 (n14), or another edit processing operation. When the page switching operation is performed, the operation proceeds to the operation of n15 or less. The page can be switched by moving up / down / left / right switches one page at a time, or by jumping by inputting a page number from the numeric keypad. In n15, it is first determined whether or not an edit has been made on the page to be switched. That is, it is determined whether or not there has been any key switch operation during the display of the page and the displayed parameter has been edited. If there is an edit, the recording pointer of the page history buffer is advanced by one (n16), and the page information of the page to be switched to the buffer area indicated by the recording pointer is written (n1).
7) The display pointer is made coincident with the recording pointer (n18). Next, the standard page information of the page specified by the page switching operation is stored in the page information register PA.
Set to GE (n19). The display on the display is changed according to the page information (n20) and the routine returns.

When the function switch 21 is turned on (n13), the operation proceeds to a function switch processing operation (n21). When the HISTORY switch 20 is turned on (n14), the process proceeds to the HISTORY processing operation (n22). Further, in the case of another edit processing operation, the corresponding processing is performed (n23) and the process returns. Other editing processing operations are processing such as parameter selection and cursor movement.

FIG. 6 is a flowchart showing the operation when the HISTORY switch 20 is turned on. Nex
t switch 20a or Previous switch 20
If only one of b is turned on, the display pointer is set accordingly (n31). That is, when the Next switch 20a is turned on, the display pointer is advanced by one, and the Previous switch 20b is turned on.
Is turned on, the display pointer is returned by one. The page information is read from the buffer area designated by the display pointer (n32). As a result, pages whose parameters have been edited in the past are sequentially displayed.

Next, reference is made to the display mode designation flag OBJ. Here, the display mode designation flag OBJ is a flag for setting various states based on page information stored in the page history buffer and designating whether or not to display the page. That is, when OBJ = 1, the cursor is displayed at the position indicated by the page information, and the function of the function switch group 21 is changed and displayed according to the ON / OFF of the shift switch 22 (n35). On the other hand, O
When BJ = 0, the display mode is changed to the standard state, that is, the position of the cursor is changed to the upper left and the function switch group 21 is not shifted (n33,
n34), display switching is performed (n35).

On the other hand, the Next switch 20a and Pr
When the evicous switch 20b is turned on at the same time, the page information of the currently displayed page is
GE. Store in BAK (n40) and HIST in PAGE
Set the contents of the ORY page (FIG. 9A) (n4
1). Then, a list screen of the edited page as shown in FIG. 9A is displayed on the display 16 (n4
2).

FIG. 9A shows the first page of the HISTORY page, in which only ten pages are displayed in two columns from the upper left in order from the latest page name. 10 remaining
Page names are displayed on the second page. Also,
In the HISTORY page, up and down switches are assigned to the switches 21-2 and 21-3 of the function switch group 21, and when the switch is turned on, the cursor moves. Also, switch 21-6
Is an Exit switch, and when this switch is turned on, the display returns to the original page display screen after exiting the list screen. The switch 21-7 is a Jump switch. When this switch is turned on, the screen is switched to the display screen of the page where the cursor is located at that time.

FIG. 7 is a flowchart showing the function switch processing operation. A unique function is assigned to the function switch 21 for each edit page, and when the function switch is turned on while the page is displayed, a corresponding operation is performed. In this operation, the HISTORY page is displayed. Only the operation will be described. First, it is determined whether or not the screen is a HISTORY page screen (n50). If it is not the screen of the HISTORY page, function switch processing corresponding to the screen is performed (n70), and the process returns.

If the HISTORY page is being displayed, it is determined which of the function switches has been turned on (n51, n52, n53). If it is the Jump switch 21-7 (n51), the display pointer is set so as to point to the buffer area corresponding to the page name indicated by the cursor at that time (n54).
The page information is read from the buffer area designated by the display pointer and set in PAGE (n55). Next, OBJ is determined (n56), and if OBJ = 0, PAG is determined.
The content of E is changed to a standard value (n57). The display switching operation is executed with these contents (n58). Next, PAGE. B
With reference to the AK (n60), it is determined whether there is any edit on this page (n61). If there is an edit, the recording pointer of the page history buffer is advanced by one (n62), and PAGE. Write BAK page information (n6
3) Return. As a result, even if parameters are edited on a certain page and another page jump is made via the HISTORY page, the page information of the certain page is recorded in the page history buffer.

When the EXIT switch 21-6 is turned on (n52), the PAGE. The page information stored in BAK is set in PAGE (n71), and PA
The display is changed according to GE (n72). Further, when the up / down switches 21-2 and 21-3 are turned on, the cursor position is changed according to the operation (n73). When the lower switch 21-3 is repeatedly turned on, the cursor moves downward from the upper left, and when the cursor moves down to the fifth step, the cursor moves to the upper right next. Further, when repeatedly turned on, the cursor moves to the lower right, and when turned on thereafter, the second page of the HISTORY page is displayed. When the upper switch 21-2 is turned on, the cursor moves in the opposite direction.

With the above operation, the page to be displayed on the display 16 has been edited by editing the parameters in the past.
It is possible to quickly and freely select within the range of the page.

The page history buffer is not limited to a fixed length of 20 pages, but may be variable length and settable by the user. The format of the buffer is not limited to the ring buffer, but may be a stack type.

In the above embodiment, the page information of the page is written in the page history buffer only when the parameter is edited. However, all the page information of the displayed page is written regardless of the editing. You may do so. This is to make it possible to cope with the possibility of using the parameter simply by referring to the parameter.

If information of the same page is already in the history, it may not be added to the history.

[0032]

As described above, according to the present invention, information on a page whose parameters have been edited in the past is stored, and the page is called and displayed according to the information. Even if you edit multiple parameters in parallel on an electronic musical instrument that is divided and displayed on the same page, you can display the previously displayed page and display the parameters that are being edited in parallel. This operation can be performed efficiently by storing the information of the page to be stored in the page information storage means.
