FIG. 2B shows a table for storing user shift data. The user shift table is a set of user shift registers USX (USP) designated by the user shift pointer USP, and stores registration numbers selected by the performer or the like. In the case of the figure, a state in which n pieces of data are stored is shown.

FIG. 3 shows the form of the display screen 16 of the display 3.

FIG. 3A is a screen showing selection of the resist shift mode. The mode area 18 has four selection areas of off, shift, jump, and user. In the illustrated case, the jump is selected and the JUMP character is highlighted. When the jump mode is selected, a jump designation area 19 is displayed on the right side of the screen.
In the jump designation area 19, a registration number decrease (minus) display area and a registration number increase (plus) display area showing the current registration number and the function of the lower function key 17 are shown. For example, when the function key 17 below the minus display area is pressed, the registration number is decremented by 1.

In the jump mode, the registration number shifts to the jump destination registration number shown on the right side.
When it is desired to change the jump destination, the jump destination registration number is changed by operating the function key 17 under the plus or minus display.

FIG. 3B shows the screen in the user mode. The case where the user is designated by the mode selection is shown, and the user's block (the USER character in the mode area 18) is highlighted. In the user mode, two pages are provided. FIG. 3B shows the case where the function page is selected, and the function FUNC in the page area 15 shown in the upper right of the screen is highlighted. In the state of FIG. 3B, when the next page switch 34 provided on the right side of the display screen 16 is pressed, the screen shifts to the screen of FIG. 3C. In this state, the edit EDIT of the page area 15 is highlighted.

FIG. 3C shows an example of an edit screen for resist shift. This screen is a screen for setting the registration sequence. In the edit screen, the sequence number 20a and the registration number 20b registered below each sequence number
Is displayed. Further, which sequence number is currently being read out is displayed using the cursor "↑" as in 21a to 21e. The position of the cursor is 2
It is controlled by the switch 17 corresponding to the displays of 3 to 26.

Switch 17 corresponding to displays 24 and 25
Respectively control the backward and forward movement of the cursor by one step. Each time the switch is operated, the position of the cursor moves back or forward by one position, and if there is registration data at the position of the cursor after backing or moving forward, based on the registration lathe number stored therein. The musical tone setting data group is read out and the operation of the electronic musical instrument is controlled.

On the other hand, the switch 17 corresponding to the display 23
Serves to move the position of the cursor to a position immediately before the position corresponding to the first sequence number (referred to as TOP position).

The switch 17 corresponding to the display 26 serves to move the cursor position to the position next to the last position in the already set registration sequence. Since the registration sequence data is not set at the destination of the cursor movement corresponding to these two switches, the musical tone setting data group is not read.

In the present embodiment, the resist sequence can be set to an arbitrary number within the range of up to 40. The cursor can be moved only within the range of 21b to 21e except for the TOP position and the sequence numbers 39 and 40. When there is a movement outside the range, the cursor is moved according to the movement instruction. Instead,
The display of 20a, 20b is scrolled and the cursor is set at the position of the target sequence number.

For example, when the cursor is located at 21e in FIG. 3C and the switch 17 corresponding to the display 25 is operated, instead of moving the cursor one position to the right from the position where the cursor is currently located, Only one of the displays 20a and 20b is scrolled to the left. That is, 20a, 20b

When the previous page switch 33 indicating the previous page shift is pressed on the screen of, the screen shifts to the function area shown in FIG. 3 (B).

In the present embodiment, as shown in FIG. 2, the register of the flag UE which indicates whether the edit page of the user shift is on the function page or the function page is provided in the register, and even after the hierarchy is transferred. That memory remains. For this reason, when the user once moved to a different hierarchy and then returned to the original hierarchy, the edit screen is directly entered when the edit screen is present, and the function screen is directly entered when the function screen is present.

The operation of this embodiment will be described below with reference to the flow charts shown in FIG.

FIG. 4 is a flowchart showing the main routine.

When the main routine is started, initialization of registers and the like is performed in step S1.
Subsequently, in step S2, key processing is performed when a key operation is performed on the keyboard.

After the key processing, in step S3, a screen changeover switch operation processing is performed. When the screen switching operation is performed, the screen number GN is set at the same time.

In the case of the resist shift mode shown in FIG. 3A, the screen is set by four states and a finer page structure in the user mode. The registration shift mode may have another screen.

Subsequently, in step S4, the screen number GN is recognized, and a branch is made according to each screen number.

In the illustrated configuration, when the screen number GN is "0", the normal screen is displayed (step S5),
When it is "1", the edit screen "1" is displayed (step S6), when it is "i", the edit screen of the registration shift screen is displayed (step S7), and when it is "i + 1", the user screen (step S8). ) Is displayed. The details of the screen changeover switch processing step S3 will be described below in more detail.

FIG. 5 shows the processing when there is an on event of the registration shift switch.

When there is an on event of the register shift switch and the process starts, it is determined in step S11 whether the register shift mode RSM is 3 (user) and the register flag UE indicating user edit is 1. . Unless RSM = 3 and UE = 1, the process proceeds to step S12, the screen number GN is set to i, and the resist shift is designated. Then, a registration shift screen is displayed on the display screen (step S13). Further, in step S14, the resist shift mode R
The cursor is displayed according to the value of SM. That is, OF
Characters corresponding to F, SHIFT, JUMP, etc. are highlighted. Succeedingly, in a step S15, it is determined whether or not the resist shift mode RSM is 2 (jump).

If RSM = 2, a jump is instructed, so the flow advances to step S16 to open a jump window as shown in FIG.

If RSM = 2 is not satisfied, the jump window is closed in step S17.

If the user's edit screen is designated in step S11, the process proceeds to step S18 according to the YES arrow to store i + 1 in the screen number GN. Then, according to the flag of UE = 1, the screen shown in FIG.
A user shift edit screen as shown in (C) and (D) is displayed (step S19). Further, the cursor 21 is displayed according to the value of the user shift pointer (USP) (step S20). That is, after entering the user edit once, when moving to the upper hierarchy and entering the user hierarchy again, the user does not enter the function page but directly enters the edit page.

If there is a key-on event of registration shift mode off (0), shift (1), jump (2), or user (3) on the registration shift screen, the number corresponding to the mode is determined in step S21. (0
(3) is stored in the register RSM and the user shift pointer USP is set to 0. Then, it merges into step S14.

FIG. 6 shows the processing when the page shift switches 33 and 34 are operated.

FIG. 6A shows the processing when the next page switch 34 is pressed in the registration shift screen of screen number GN = i. When the process starts, step S2
6, a flag UE indicating user shift edit
1 is set up and merges into the position A1 shown in FIG.

As shown in FIG. 6B, the screen number GN =
When the previous page switch 33 is pressed on the i + 1 user shift edit screen, 0 is stored in the flag UE indicating the user shift edit (step S27), and the flag joins at the position indicated by A2 in FIG.

In the case of FIGS. 6A and 6B, the screen number is changed to i + 1 and i in step S18 and step S12 corresponding to each operation.

FIG. 7 shows G showing a user shift edit.
The process of operating the movement switch on the screen of N = i + 1 is shown. When the cue switch 23 is operated, 0 is stored in USP in order to move the user shift pointer USP to the beginning in step S81.

When the decrease switch 24 is operated, the value of the user shift pointer USP is decreased by 1 in the limit of 0 in step S82.

When the increment switch 25 is operated, the value of the user shift pointer USP is incremented by 1 up to the next address of the final address (n) where the data is stored and the smaller address of 40 in step S83. Let

When the tail switch 26 is operated, in step S84, the user shift pointer USP stores the smaller one of n + 1 and 40, which is next to the last data (the first address where data can be stored), in USP.

In accordance with each switch, the above step S81
After any of the processing from S84 to S84 is performed, step S
At 85, it is determined whether or not the user shift pointer USP indicates the address 0 or n + 1 where the registration sequence data does not exist. If it is determined that the address does not have a registration sequence, the registration is not read and step S88 described later is executed.

On the other hand, if it is determined in step S85 that USP is neither 0 nor n + 1, that is, there is registration sequence data at the position indicated by USP, the user shift pointer (US
The data designated by P) is read and written in the registration number RN.

Then, the corresponding registration is read out based on the written registration number RN, and the electronic musical instrument is set up (step S87).

In step S88, according to the value of the user shift pointer USP, 20a, 20
The display of b is scrolled and the cursor "↑" is moved.

FIG. 8 is a flow chart showing the processing of the on event of the right foot switch of the foot pedal. The foot switch has different functions depending on the operation mode.

When the right foot switch is turned on and the process is started, it is determined in step S31 whether the registration shift mode RSM is 0 (off).

If RSM = 0, it is instructed to turn off, so the flow proceeds to step S32, the processing of other foot switches is performed, and the processing is ended.

If RSM = 0 is not satisfied, the process proceeds to step S33 in accordance with the NO arrow, and branching is performed according to the value of RSM. That is, if RSM = 1, shift processing,
If RSM = 2, jump processing is performed, and if RSM = 3, user processing is performed.

When RSM = 1, the register shift mode is instructed. If the registration number RN has not reached the final 16 in step S34, the registration number RN is incremented by 1 and stored in the register RN.

In the jump mode, the jump number JN indicating the address of the jump destination is stored in the registration number RN (step S35).

In the user mode, it is determined in step S36 whether the user shift pointer USP is the last address n or the previous address n-1. If the address is earlier than that, go to step S37,
The value of the user shift pointer is incremented by 1. Then, the user shift data USX (USP) at the position of the corresponding user shift pointer is stored in the registration number RN (step S38).

If the determination in step S36 is YES, n-1 even if the user shift pointer USP is n.
, The user shift pointer U in step S39
The value of SP is set to the last address n. Succeedingly, in a step S40, an end of the resist shift is displayed. After that, the user shift data USX (n) at the address n
Is stored in the registration number RN (step S4).
1).

When the registration number RN is set in this way, in the next step S42, the registered registration is read out based on the value of the registration number RN, and the state of the electronic musical instrument is set up. After that, the other foot switches are processed (step S3).
2), the process ends.

FIG. 9 shows a registration switch on-event processing routine at GN = i + 1 for instructing the user shift edit screen.

When the process starts, the number of the operated resist switch is stored in the register RSW (step S51). Next, in step S52, it is determined whether or not the user shift pointer USP is 0.
If it is determined that USP is 0, the cursor is currently at the TOP position and there is no possibility that the registration sequence will be written. Therefore, the process related to the writing is bypassed and the process proceeds to step S55. On the other hand, USP is 0
If it is determined that the registration switch is not operated, it is determined whether the registration switch operation is performed at the same time as the operation of the set switch.
This is performed by determining ET = 1 (step S5)
3).

Now, the event processing of the set switch will be described. FIG. 10 shows the event processing of the set switch.

When the set switch is turned on, FIG.
As shown in (A), the process proceeds to step S64, where the set flag SET is set to 1 and the insert flag INS is set to 0. That is, set priority handling is performed. Next, in step S65, a cursor is displayed at the position of the set registration number (“SE shown at 29 in FIG. 3).
The character "T" is displayed in reverse video.

When the set switch is turned off, FIG.
As shown in 0 (B), in step S66, the flag SET is set to 0, and the cursor at the designated registration number is erased (step S67).

Returning to FIG. 9, the judgment in step S53 is Y.
If it is ES, it means that the resist switch is operated while pressing the set switch, and the process of registering the corresponding resist number is performed.

That is, in step S61, the value of the registration switch RSW is set to the user shift pointer USP.
Stored in the user shift data USX (USP) specified by. Next, the user shift pointer (USP) is n + 1
To determine whether or not. The user shift data is numbered from 1, and the cursor points to the first free block (n + 1), so USP = n + 1
When, it means that the sky area has advanced by one. Therefore, the number of data n is incremented by 1 to register the next data (step S63). Then, the smaller one of the value obtained by adding 1 to the updated n and 40 is stored in the user shift pointer USP (step S64).

If the set switch is not operated in step S53, it is determined in next step S54 whether or not the insertion switch INS is operated.

Here, the function of the insertion switch INS will be described.

FIG. 11 shows the processing of the insertion switch.

When the insertion switch is turned on, step S
71, the set flag SET is 1 or n = 40
It is determined whether or not. If the set flag SET = 1,
According to the setting priority handling, the operated insertion instruction is ignored, while if n = 40, the sequence is already full, so the insertion instruction is ignored and 0 is stored in the flag INS (step S74).

The set flag SET is not 1 and n
If not = 40, insert flag (character of INS)
Is reversed (step S72). That is, register I
The NS cycles through both 0 and 1 states. Then, in step S73, the insertion cursor (reverse display) is erased or displayed in accordance with the value (0/1) of the insertion flag INS.

Returning to FIG. 9, I is determined in step S54.
If NS = 1, insertion is instructed. Therefore, the data after the USP of the user shift data is shifted by one, and the data after the USP is shifted by one, and the empty space is set to 1 at the location indicated by the USP.
Form one. The RSW designated by the operation of the resist switch is written in this empty space (step S5).
7). Next, in order to accept the increase in the number of data due to the insertion, the number of data n is increased by 1 (step S58), 0 is stored in the resist INS indicating the insertion mode, and the insertion mode is ended (step S59). In addition, the cursor (reverse display) indicating the insert mode is erased (step S6).
0).

After these processes, the operated registration switch number RSW is stored in the registration number RN (step S55), the registration condition set based on the value of this RN is read out (step S56), and the electronic musical instrument is read. To the indicated state.

When the external storage interface 16a is provided in the electronic musical instrument of this embodiment so that the panel state for which the registration sequence is set can be stored and read in the external storage medium 17a such as a floppy disk, the registration sequence When the set panel state is read into the RAM 10, if the TOP position is set as the initial state after the reading, the registration sequence can be used by the foot switch immediately after the reading.

Further, the registration shift of the foot switch can be switched to three functions of off and shift, jump, and user shift. For example, when the function set for jump is switched to user shift, the conventional electronic shift is performed. In the musical instrument, the first register sequence was suddenly executed, but by setting the TOP position as the initial position when the switching is performed, the panel state up to that point is lost due to the switching. Was also avoided.

[0086]

As described above, according to the present invention,
Since the address position for reading can be placed at the position immediately before the first control information stored in the sequence storage means, the sequence of the step control means is instructed to be advanced one by one. Since it is possible to call from the first control information stored in the storage means, the operation at the time of performance becomes easy and the operation performance of the electronic musical instrument is improved.
