BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for executing a plurality of types of control functions for a predetermined control target and a control processing program.

[0002]

2. Description of the Related Art In various machines, equipment, instruments, etc.,
A control device is provided that executes a plurality of types of control functions for the specific control target. For example, a communication device such as a facsimile machine or a mobile communication terminal is provided with a control device that executes a plurality of types of communication processing functions for communication means such as a modem connected to a communication network. Alternatively, an information processing device such as a personal computer or a personal digital assistant is provided with a control device that executes a plurality of types of information processing functions for peripheral devices. Alternatively, in an electronic musical instrument that plays a piece of music, D that executes a plurality of types of effect functions for processing the generated musical tone signals to give effects
A control device for setting function execution means such as SP (digital signal processor) is provided. In such various machines, devices, instruments, etc., a plurality of operators and LCs are usually provided in addition to or integrated with the control device.
Display means such as D and CRT are provided. Therefore, the user operates the operator while confirming the state of the controlled object and the state of the control function displayed on the display means, and inputs a command for causing the control device to execute a desired control function. .

For example, some conventional electronic musical instruments have a plurality of types of effect functions in order to process a generated musical tone signal to give an effect. The effect contents of the effect function are distortion that distorts the musical tone signal and changes the timbre, delay that delays the musical tone signal to give a reverberation effect, reverb that specifies the sound field environment (hall, church, live house). Etc. In particular, in recent years, there are electronic musical instruments that have an effect function that creates a tone color that surpasses that of an acoustic instrument, and an effect function that can specify the same sound field environment as a specific performance venue in a specific country.

[0004]

However, in the conventional control devices for various machines, devices, appliances, etc., the more complicated the control functions that can be executed by the user, the more complicated the operation becomes. Therefore, the user not only needs to confirm the state of the controlled object and the state of the control function displayed on the display means, but also needs to operate the operator while referring to the command corresponding to the control function in the instruction manual. .

For example, in a conventional electronic musical instrument having a plurality of kinds of effect functions, a plurality of effect functions can be designated at the same time by an operation, and a parameter value in each effect function can be changed by an operation. These operations were too complicated.
For this reason, it has been difficult for general users to freely use such plural kinds of effect functions provided in the electronic musical instrument. As a measure against this, some effect functions are combined into one pattern, and a plurality of types of patterns are preset on the manufacturer side,
There is also proposed an electronic musical instrument capable of simultaneously executing a plurality of effect functions according to a designated pattern by a simple selection operation by a user. However, such an electronic musical instrument not only limits a user's free idea and improvisational performance, but also has a problem that various effect functions cannot be fully utilized.

An object of the present invention is to make it possible to make full use of these control functions by a simple operation even in the case where various types of control functions are provided in control devices for various machines, devices, appliances and the like. It is to be.

FIG. 3 is a schematic block diagram showing the algorithm of the effect function executed in the DSP 9. Algorithm has multiple effect blocks 2
It has a structure in which 1 to 32 are combined. In the example of FIG. 3, four insertion effects 1 to 4 including blocks 22 to 25, a reverb of block 28, a chorus of block 29, and a master of master block 32 are used. Three systems (System
m) It has a structure that combines effects. In addition, blocks 26 and 2 for synthesizing a plurality of musical sound data
There are 7, 30, and 31.

The insertion effect is an effect function for performing processing such as distortion, delay, and pitch shift on musical sound input data. The system effect is an effect function for performing sound field environment setting processing by reverb, chorus effect by chorus, and equalizer processing by master. A specific type of effect function is assigned to each block of the insertion effect and the system effect, and one or a plurality of parameter values in each type of effect function are set.

FIG. 4 shows a table of devices (operators) stored in the ROM 3 and a table of effect function states of the electronic musical instrument, that is, a musical instrument state. The numbers (x) from “00” to “18” correspond to each device, and the numbers (y) from “00” to “15” correspond to each instrument state, that is, the state of the effect function. The instrument status is MAIN EFX INS indicating the normal insertion effect function status, MAIN EFX SYS indicating the normal system effect function status, and EFX indicating the status for setting the effect function parameter.
PARA INS1 to EFX PARA MAS, EFX TYP showing the state of setting the type of effect function
There are 16 states consisting of E INS1 to EFX TYPE MAS. When the device with an arbitrary number "x" is operated, the state transition command is uniquely determined according to the instrument state number "y" at that time.

5 to 7 are specification tables in which each device designated by the number x and each musical instrument state designated by the number y are combined as an array, and are stored in the ROM 3 in advance. FIG. 5 shows L1 to L5 and EX of FIG.
A specification table combining each IT switch and each instrument state, FIG. 6 is a specification table combining each switch R1 to R5 of FIG. 2 and each instrument state, and FIG. 7 is each slider SL1 to SL8 of FIG. It is a specification table which combined a slider and each musical instrument state. Each switch and each slider is a controller for specifying the effect,
It functions as an operator for presenting an effect and an operator for selecting an effect, which will be described in more detail.

For example, in the specification table of FIG. 5, when the switch L1 (device number 00) is turned on,
When the instrument state is "EFX PARA INS1" (state number 02), that is, the parameter setting state of the insertion effect 1, the corresponding specification data is uniquely "display (PARA, INS1)". This specification data (“0002” in the xy array) is a state transition command “display the parameters of the insertion effect 1.” When the switch L5 (device number 04) is turned on, the musical instrument state is “EFX.
In the case of TYPE INS1 ”(state number 09), that is, the type setting state of the insertion effect 1, the corresponding specification data is uniquely“ switch (EFX, I
NS1) ". This specification data (“0409” in the xy array) is a state transition command “switch on / off of automatic setting of insertion effect 1”. Alternatively, in the specification table of FIG.
When the switch SL2 (device number 01) is turned on and the musical instrument state is "EFX PARA INS" (state number 00), that is, the normal state of the insertion effect 1, the corresponding specification data is uniquely " Change (INS1,2) ". This specification data (“0100” in the xy array) is a state transition command “change the parameter value of insertion effect 1.” Other specification data will be described in more detail later.

FIG. 8 shows an area for effect functions in the RAM 4, which is the insertions 1 to 4 of the insertion effect and the system effect shown in FIG.

Next, the previous output value of the slider SL (n) stored in the register FVALUE (n) is set to V
It subtracts from the current output value stored in ALUE (n) and stores the subtracted value in the register SABUN (step D3). Then, it is determined whether or not the absolute value of SABUN exceeds a predetermined value (minimum change amount) (step D
4). If the value exceeds the predetermined value, it means that the slider SL (n) has been operated, so the value "9 + n" is stored in the input event register (step D5). As shown in FIG. 4, the slider device numbers are “10” to “1”.
Since it is "7", the device number of the slider SL (n) is specified by adding "9" to the value of the pointer n. That is, the device number of the operated slider is stored in the input event register.

Next, the current output value stored in the register VALUE (n) is stored in the input value event register (step D6). Then, "1 (event occurrence)" is set to the event occurrence flag (step D
7). Further, the current output value stored in the register VALUE (n) is stored in the register FVALUE (n) (step D8). After this, or when the absolute value of SABUN is less than or equal to the predetermined value in step D4, n
Is incremented to specify the next slider (step D9). At this time, it is determined whether or not the value of n exceeds "8" (step D10). That is, it is determined whether or not the search for all sliders has been completed. The value of n is "8"
If it is the following, the process proceeds to step D2. If the value of n exceeds “8” in step D10,
Since all sliders have been searched, the process returns to the main flow.
