DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selection control apparatus for an electronic device, and more particularly to a group control and an item selection for a plurality of groups of processing or control items by using a plurality of operators commonly used for these groups. By automatically shifting to item selection at the end, quick item selection with a small number of operators is enabled.

[0002]

2. Description of the Related Art Conventionally, there has been known an effect applying apparatus for selectively applying a plurality of effects such as distortion, chorus, and reverb to a tone signal derived from a musical instrument such as a guitar.

In such an effect imparting device, a plurality of selection switches are shared in the first and second selection modes,
In the first selection mode, a desired effect program is selected by operating any of the selection switches, and in the second selection mode, distortion, chorus, reverb, etc. in the effect program related to the selection is operated by operating any of the selection switches. On / off (giving / non-giving) of each effect is selected.

[0004]

According to the above-mentioned conventional effect applying apparatus, the selection switch and the effect program are one in number.
Because of the one-to-one correspondence, the effect program can be selected only up to the number of selection switches, and there is a disadvantage that the range of program selection is narrowly limited.

To increase the range of program selection, it is necessary to increase the number of effect programs, but it is necessary to correspondingly increase the number of selection switches, thereby avoiding complicated switch arrangement and circuit configuration. Absent.

An object of the present invention is to enable a desired item to be quickly selected from a large number of selection items with a small number of operators in an electronic device such as an effect imparting device.

[0007]

According to the present invention, there is provided an electronic apparatus for processing or controlling a selected item of a selected group among a plurality of groups of processing or control items. Or a processing means for performing processing in a processing mode designated in any of the second processing modes. In the first processing mode, any one of a plurality of groups selected from the plurality of groups is selected. The process of selecting an item is performed according to at least one operation of the plurality of selection operators, and in the second processing mode, the process of selecting an arbitrary group from the plurality of groups is performed by the plurality of processes. And mode designating means having mode switching operation means, wherein the first operation means is operated in response to operation of the mode switching operation means.
Alternatively, the second processing mode is specified, and in the state where the second processing mode is specified, the first processing mode is automatically specified in response to completion of the selection processing of the second processing mode. And a selection control device.

[0008]

According to the configuration of the present invention, the group selection and the item selection are performed separately by a plurality of operators commonly used for these, so that, for example, the selection of five groups and the selection of five items are performed in five steps. If the operations are separately performed by one operator, selection of 25 items can be performed by the five operators and the mode switching operation means. In addition, since the mode is automatically shifted to the item selection mode in response to the end of the group selection process, the item can be quickly selected without a mode switching operation from the group selection mode to the item selection mode.

In the structure of the present invention, a third processing mode is provided in addition to the first processing mode (item selection mode) and the second processing mode (group selection mode). Then, the processing different from the processing contents in the first and second processing modes may be performed according to at least one operation of the plurality of selection operators. In this case, the mode specification automatically specifies the first processing mode only when the selection processing is performed in the second processing mode, and in the third processing mode, sets the other mode only by operating the mode switching operation means. specify. This way,
In the third processing mode, it is possible to move to another mode after operating the selection operation element a required number of times.

[0010]

FIG. 1 shows an effect applying apparatus according to an embodiment of the present invention. In this example, the selection and application of the effect is controlled by a microcomputer. The effect imparting device of this embodiment is arranged on a floor or the like and can be operated by a guitar player or the like with his or her feet.

Includes 5 effect programs like 1-2-5 ...
Each effect program represents on / off of five types of effects: compressor, distortion, equalizer, chorus, and delay / reverb.

The selection functions of the switches FS _{1 to} FS ₅ for each mode are as follows (1) to (3).

(1) Mode 0: This mode is a program selection mode. In this mode, it can be selected by a switch FS ₁ ~FS ₅ Any of the five effect programs belonging to the bank according to the selection. In this case, switch FS ₁ ~FS ₅ respectively correspond to the program numbers 1 to 5 of each of the banks shown in FIG. 3, for example, turning on the switch FS ₁ with respect to the first bank,
The effect program 1-1 is selected.

(2) Mode 1 This mode is a bank selection mode. In this mode, any one of the first to tenth banks can be selected. That is, the switch MS
When turning off the switch MS after shifting to ON mode 1 can be selected one of the first to fifth bank by a switch FS ₁ ~FS _5. In this case, switch FS ₁ ~FS ₅ corresponds to the first to fifth bank respectively (bank number 1-5). Further, while continuing the ON operation of the switch MS after the shift by turning on the switch MS in mode 1, it is possible to select one of the sixth to tenth bank by the switch FS ₁ ~FS _5. In this case, switch FS ₁ ~FS ₅ are sixth to each of the first
0 bank (bank numbers 6 to 0). The combination of the program selection of bank selection and the mode 0 mode 1, it is possible to select 50 effects programmed by switches FS ₁ ~FS _5, MS. Since only the bank switching is not performed a plurality of times in succession, when any bank is selected in the mode 1, the mode automatically shifts to the mode 0 without operating the mode switching switch MS.

(3) Mode 2 This mode is an effect on / off selection mode. In this mode, can be modified to five effects on / off by a switch FS ₁ ~FS ₅ for the effect program according to the selection. in this case,

The knobs N _{1 to} N ₅ of the _first to fifth groups correspond to the effects of the compressor to delay / reverb, respectively. Parameters such as the degree of the effect corresponding to the three knobs for each group are provided. Can be set.

In the vicinity of the mode change switch MS, a bank number display BND and a program number display PN are provided.
D is provided. Each of the displays BND and PND is a 7-segment display, and the display elements (segments) of each display belong to the display element group 16 in FIG.

In the mode 0, the bank number display BND displays the bank number related to the selection in a lighting state.
In mode 1, the selected bank number is displayed in a blinking state, and in mode 2, the same display as in mode 0 is performed. Also, the program number display PND
Displays the selected program number in a lit state in any of modes 0 to 2.

The CPU 18 executes various processes for selecting and giving effects in accordance with a program stored in a program memory 20 composed of a ROM (read only memory).
5 will be described later.

The program memory 20 stores 50 microprograms for signal processing corresponding to 50 selectable effect programs, respectively, in addition to the programs for the CPU. And various parameters are stored.

The working memory 22 is composed of a RAM (random access memory), and includes a storage area used as a register or the like when the CPU 20 performs various processes. Registers related to the embodiment of the present invention include the following (1) to (3).

(1) Mode register MODE ...
One of the mode numbers 0 to 2 is set.

(2) Bank register: This is one in which any of bank numbers 1, 2, 9, and 0 is set.

(3) Mode changeover switch on flag MS
ON: This is a 1-bit register. If it is 1, it indicates that the mode switch MS is on, and if it is 0, it indicates that the switch MS is off.

The DSP 24 can add the above-described five effects to the digital input signal DI based on microprograms and parameters stored in the RAM 26. The DSP 24 uses a delay RAM 28 as necessary. I have. As the digital input signal DI, a signal obtained by digitally converting an analog tone signal such as a guitar sound signal input from the signal input terminal IN by the A / D conversion circuit 30 can be used. It may be. The digital tone signal DO from the DSP 24 is supplied to the mute circuit 32.

The mute circuit 32 is provided to prevent a click sound from being generated when clearing the data in the RAM 28. The mute circuit 32 changes the mute instruction signal MT from the bus 10 to "1" / "0". The mute is turned on / off gradually in response.

The digital tone signal from the mute circuit 32 is converted to an analog tone signal by the D / A conversion circuit 34. Then, the analog tone signal from the D / A conversion circuit 34 is supplied to the sound system 36 and converted into sound.

FIGS. 4 and 5 show the flow of the processing of the main routine. This routine is started when the power is turned on or the like.

In step 40, an initialization (initial setting) routine is executed. That is, the register MOD
0 (corresponding to mode 0) and 1 (corresponding to the first bank) are set in E and BANK, respectively. Further, the micro program and the parameter relating to the first effect program of the first bank are read from the memory 20 and the DSP 24
Is written to the RAM 26.

Next, at step 42, display BND and the bank number 1 and program number 1 according to the initial setting and displays each PND, and LED light L ₁ corresponding to the program number 1 and the other LED Turn off the light. Then, the process proceeds to a step 44.

In step 44, the mode switch M
It is determined whether S has an on-event. If the result of this determination is affirmative (Y), the operation proceeds to step 46 where the register MO
It is determined whether the value of DE is 0 (program selection mode).
When the process first reaches the step 46 from the step 40, the determination result of the step 46 becomes affirmative (Y), and the process proceeds to the step 48.

At step 48, 1 is set in the register MODE.
(Corresponding to mode 1) is set. And step 5
Passes to 0, blink the entire LED bank number display and L ₁ ~L _5. This is to urge the operator to select a bank. The first time came to step 50 from step 40, LED of L ₁ ~L ₅ flashes with indicator BND blinks while displaying the bank number 1.
Thereafter, the process proceeds to step 52.

At step 52, the flag MSON is set to 1. When the processing in step 52 is completed or when the result of the determination in step 44 is negative (N), the process proceeds to step 54, where it is determined whether or not the switch MS has an off event. If the result of this determination is affirmative (Y), the routine proceeds to step 56, where 0 is set in the flag MSON.

When the processing in step 56 is completed or when the result of the determination in step 54 is negative (N), the process proceeds to step 70 in FIG. Subsequent processing will be described later.

If the decision result in the step 46 is negative (N), a decision is made in a step 58 whether the value of the register MODE is 1 (bank selection mode). If the result of this determination is affirmative (Y), the routine proceeds to step 60, where 2 (corresponding to mode 2) is set in the register MODE. Then, the process proceeds to a step 62.

In step 62, the bank number display on the display BND is changed from a blinking state to a lighting state.
For example, if the bank number 1 is blinking in the mode 1 state, the bank number 1 is lit. Thereafter, the process proceeds to step 64.

[0041] At step 64, the on / off control of the LED of L ₁ ~L ₅ according to the on / off state of the individual effects the effect program that is currently selected. For example, when the first is the equalizer and delay / reverb and the effect on the effect programs and other effects of the first bank is off, L ₃ and L LED ₅ becomes lit, the other of L ₁ , LED of L ₂ and L ₄ is turned off. After step 64, the process moves to step 52, and the subsequent processing is performed in the same manner as described above.

If the decision result in the step 58 is negative (N), mode 2 (effect on / off selection mode)
Therefore, in step 66, the register MODE
And returns to mode 0 (program selection mode). Then, the process proceeds to step 68, where only the LED corresponding to the currently selected effect program is turned on, and another LED is turned on.
Turn off the ED. For example, as in the above example, the LEs of L ₃ and L ₅ for the first effect program in mode 2
If the mode shifts to mode 0 when D is lit, the LED goes low.
Only ₁ is turned on. After step 68, the process moves to step 52, and the subsequent processing is performed in the same manner as described above.

Next, referring to FIG. 5, the selection switch FS ₁
Illustrating processing modes 0-2 due to the operation of ~FS _5.

At step 70, the switches FS _{1 to} FS
_It is determined whether any of ₅ has an ON event. If the determination result is affirmative (Y), the process proceeds to step 72, where the value of the register MODE is 0 (in the program selection mode).
judge. If the result of this determination is affirmative (Y), the flow proceeds to step 74, where mute instruction processing is performed. That is, a mute instruction signal MT = "1" is sent to the mute circuit 32 via the bus 10, and the mute is started. Then, the process proceeds to step 76.

In step 76, R
The data clear of AM28 is instructed. Then, the process proceeds to step 78, where the microprogram and the parameters in the RAM 26 are rewritten. That is, the switches FS _{1 to} FS
_The micro program and the parameters related to the effect program selected by one of the on operations of ₅ are read out from the memory 20 and written into the RAM 26. Thereafter, the process proceeds to step 80.

In step 80, the program number of the effect program related to the selection is displayed on the display PND. The LED corresponding to the effect program related to the selection is turned on, and the other LEDs are turned off. For example, when selecting the fifth effect program of the first bank by a switch FS _5, together with the program number 5 is displayed on the display device PND, only the LED of L ₅ corresponding to the switch FS ₅ is turned on.

Next, at step 82, if the bank number indicator BND is in a blinking state, it is changed to a lighting state. When the process first proceeds to step 82 after automatically shifting to mode 0 in step 98 described later, the bank number of the newly selected bank is displayed blinking. Is switched. Thereafter, the process proceeds to step 84.

In step 84, it is determined whether or not the clear processing of the RAM 28 has been completed. This judgment result is negative (N)
If so, the determination in step 84 is repeated. When the determination result of step 84 is affirmative (Y), the mute of the mute circuit 32 is released by setting the mute instruction signal MT to "0" in step 86. Since the mute circuit 32 is in a mute state until the clear processing of the RAM 28 is completed, it is possible to prevent noise such as a click sound from being generated from the sound system 36 during the clear processing.

If the decision result in the step 72 is negative (N), the process shifts to a step 88, where the register MODE is selected.
Is 1 (in bank selection mode). If the result of this determination is affirmative (Y), the routine proceeds to step 90, where it is determined whether the flag MSON is 0 (whether the switch MS has been turned off). If this determination result is affirmative (Y), the procedure proceeds to step 92, switch FS ₁ ~FS either turned on by number of the selected bank ₅ (FS ₁ ~FS
₅ ) to register B
Set to ANK. Further, if the determination result of step 90 is negative (N) sets the number of banks in accordance with the selection (either the corresponding 6-0 respectively FS ₁ ~FS ₅₎ to register BANK. For example, assuming that turns on the switch FS _5, the on-time (corresponding to the fifth bank) bank number 5 the register BANK If the flag MSON is 0 to is set, if the flag MSON is 1 when the on Bank number 0 (corresponding to the tenth bank) is set in the register BANK. Thereafter, the process proceeds to step 96.

[0050] At step 96, turns off the entire LED of L ₁ ~L ₅ which flashing in step 50. this is,
This means that the selection of a new bank has been completed. Further, the display of the bank number display BND is changed to the bank number (newly selected bank number) of the register BANK. In this case, the blinking state of the bank number display is continued as it is, and the user is prompted to select an effect program for the newly selected bank. Thereafter, at step 98, 0 is set in the register MODE. As a result, the mode is automatically set to mode 0, and a new effect program can be selected.

If the decision result in the step 88 is negative (N), mode 2 (effect on / off selection mode)
And the process proceeds to Step 100. In step 100, clear if any of the on-operation by the selected turned ON / OFF state shown effective data in the RAM26 the effect of the switch FS ₁ ~FS _5, reversing the ON if off. Then, the process proceeds to step 102, where the state of the LED corresponding to the turned on switch (effect related to selection) is turned off if it is on, and turned on if it is off. For example, assuming that turn on the switch FS _3, in step 100, if the effect data in the RAM26 had instructed to turn ON the equalizer effect (or off), the effect data of the equalizer effect off (or on ), And in step 102, L
LED ₃ switches from lighting (or turning off) to turning off (or turning on).

When the processing in step 86, 98 or 102 is completed or when the result of the determination in step 70 is negative (N), the other processing is executed in step 104 and then the processing proceeds to step 44 in FIG. Then, the subsequent processing is repeated in the same manner as described above.

The present invention is not limited to the above embodiment, but can be implemented in various modifications. For example, the following changes (1) to (3) are possible.

(1) The device and mode are not limited to program selection, bank selection, and effect on / off selection of the effect imparting device. For example, in an electronic musical instrument, in the first mode, a tone program of a selected bank is selected, in the second mode, a bank is selected, and in the third mode, a selected tone program is edited. In the first mode, a variation pattern of the rhythm style related to the selection (for example, intro,
The present invention can also be applied to a case where a rhythm style such as march or waltz is selected in the second mode, and a variation pattern related to the selection is edited in the third mode.

(2) The mode switching operation means is not limited to one using a single switch MS, but may be one using a plurality of switches (for example, switches having the same number of modes).

(3) Regarding the parameters related to the microprogram, instead of using those in the memory 20,
A player or the like may appropriately read and use the information registered in the memory 22.

[0057]

As described above, according to the present invention, group selection and item selection for a plurality of groups of processing or control items are performed separately by a plurality of operators shared with them, and automatically at the end of group selection. Since the process is shifted to the item selection, the effect of quickly selecting an item with a small number of operators can be obtained.

In the processing modes other than the group selection and the item selection, the processing is shifted to the item selection in response to the operation of the mode switching operation means. There are advantages too.
