Abstract

PURPOSE:To allow performance without mis-operations by providing a function switching means which provisionally assign the same operation content control functions to concentrically disposed operating elements such as cursor switches. CONSTITUTION:A power source switch 2, a function switch 3, a cursor switch 4 and a display device 5 are provided on the operation panel of a sound source device. LEDs 6 are provided in correspondence respectively to the function switches 3a to 3g. The same operation content control functions can be provisionally assigned to these operating elements by a switch control section 14. the control of the operation contents during the performance is facilitated by executing the function switching prior to the performance of music. For example, the switching functions of the effects (tremolo, chorus, etc.,) at the time of the performance are provisionally assigned to the cursor switches 4a to 4d disposed concentrically with 4 pieces of switches, then the switching of the effects is executed by turning on any of the cursor switches during the performance.

Description

DETAILED DESCRIPTION OF THE INVENTION (al) Industrial Field of Use This invention relates to electronic musical instruments, and particularly to improving the operability of selecting and switching functions thereof.

(b) Conventional Technology With advances in electronics technology, electronic musical instruments such as electronic organs and synthesizers have become significantly more sophisticated and smaller.

Highly functional electronic musical instruments generate musical tones based on a large number of parameters, and can produce various tones and effects by changing the parameters. For this reason, a large number of operators such as switches and volumes are arranged on the panel surface to set and change the respective parameters.

By the way, as musical instruments are becoming smaller as described above, the size of each operator is limited, and the space between the operators is also limited. On the other hand, in order to take full advantage of the advanced functionality of electronic musical instruments, performance techniques that vary the tone and switch effects such as tremolo and chorus during the performance of a song are becoming widespread. C1 Problems to be Solved by the Invention In order to perform this kind of performance method, it is necessary to operate predetermined operators during momentary intervals during the performance, but as mentioned above, in recent electronic musical instruments, it is difficult to use the limited space available. Since the control panel has dozens to hundreds of controls (switches, volume, etc.), it is extremely difficult to find the desired control in an instant and place your finger on that control without making a mistake. .

If the wrong operator is operated, the musical tone may change to an undesired tone, making further performance impossible.

In order to overcome these shortcomings, methods have been proposed, such as providing a display to provide guidance on the next control to be operated, or increasing the size of only frequently operated controls. Both methods have the drawback of increasing the size of the device and increasing costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic musical instrument that solves the above problems by switching a plurality of centrally arranged operators to control the same parameter during the performance of a piece of music.

(Means for Solving Problem d1) The present invention provides an electronic musical instrument having a plurality of operators that are centrally arranged and assigned different operation content control functions, wherein the plurality of operators are configured to perform the different operations. The present invention is characterized in that a function switching means is provided for temporarily assigning the same operation content control function instead of the content control function.

(e) Function In the electronic musical instrument according to the present invention, the same operation content control function can be temporarily assigned to a plurality of centrally arranged operators (function switching means).

By performing this function switching before playing a piece of music, it is possible to easily control the operation contents during the performance. for example,
The cursor switch group consists of four switches (top, bottom, left, and right) that are centrally arranged (cursor switches are generally larger than other function switches), and they have effects during performance (tremolo chorus). By temporarily assigning a switching function (e.g.), the effect can be switched by turning on any cursor switch (it doesn't matter if it's one or more) during a performance. In this manner, by assigning the operation content for switching control during a performance to a group of conspicuous and convenient operators, it is possible to switch and adjust the operation content without fail during a momentary interval during a performance.

if) Examples The detailed configuration of the present invention will be explained below using examples, but in order to simplify the explanation, only the sound source device will be explained in an electronic musical instrument in which a controller, a sound source device, and a sound system are each configured separately. .

FIG. 1 is an external view of the sound source device. A performance controller such as a keyboard and a sound system such as an audio amplifier and speakers are externally connected to this sound source device, and all of these are connected to form an electronic musical instrument system. The operation panel of this sound source device includes a power switch 21, a function switch 3 (6a to 6g), and a cursor switch 4 (4a to 4).
d) A display 5 is provided, and LEDs 6 (6a to 6g) are also provided corresponding to each of the function switches 3a to 3g.

The VOICE switch 3a is a switch for selecting a tone. When this switch is pressed, the mode becomes a tone selection mode, and by operating the cursor switches 4a to 4d, the tone color can be selected and the volume can be adjusted.

The EDIT switch 3b is a switch for adjusting (editing) the timbre parameters of each tone. Pressing this switch enters edit mode, and by operating cursor switches 4a to 4d, tone parameters (EG ATTA (J RATE (rise parameter), EG RELEASE R
ATE (attenuation parameter), etc.) and increase/decrease the parameter value.

The tremolo/speed (TREMOLO/5PEED) switch 3C and the chorus (CHORtJS) switch 3d are used to selectively turn on the tremolo effect and the chorus effect.
This is a switch to turn off. Also, SHIFT
) Turn on switch 3g and tremolo/speed switch 3C at the same time to enter tremolo speed adjustment mode.
The tremolo speed can be adjusted by operating the cursor switches 4a and 4b.

The reverb/depth (REVERB/DEPTH) switch 3e is a switch for turning on and off the reverb effect. Also, if you turn on this switch and shift switch 3g at the same time, the depth of the reverb effect (the length of the reverberation) will change.
The adjustment mode is entered, and the reverb depth can be adjusted by operating the cursor switches 4a and 4b.

Resist/Mesori (REC; I ST/MEMO3
Y) The switch 3f is a switch used when storing/reading a combination of set tones and effects.

Turn on this switch to enter register (memory) mode. Cursor switch 4c.

When you select the memory area to store by number using 4d,
The current state (combination of tones and effects) is stored. When this switch and the shift switch 3g are turned on at the same time, the memory (read) mode is entered, and when a memory area is selected using the cursor switches 4c and 4d, the state stored in that area is read.

Further, when the tremolo/speed switch (hereinafter simply referred to as "tremolo switch") 3c, shift switch 3g, and cursor switch (any one of 4a to 4d) are turned on at the same time, a tremolo control mode is entered.

In this mode, the tremolo effect/chorus effect can be switched by turning on any one to four cursor switches. As shown in the figure, the cursor switch 4 has large switches arranged in a concentrated manner, so it can be operated quickly, and effects can be changed even during a momentary interval during a performance. To cancel this mode, the tremolo switch 3c, shift switch 3g, and cursor switch 4 may be turned on simultaneously again.

control. The matrix LED 20 displays the content of the operation and the function of the cursor switch at that time. The sound source circuit 17 generates musical tones based on the musical tone data sent from the CPU10, and outputs them to an externally connected sound system.

FIG. 3 shows a circuit diagram of the switch control section 14. This circuit has a function of transmitting on/off of each switch (function switches 3a to 3g and cursor switches 4a to 4d) to CPU10, and a switching control function in the tremolo control mode. Each of the function switches 3a to 3g and cursor switches 4a to 4d is connected to the "H" power supply and the IN 1 to INII of the CPUI O, respectively.
(input port), and a pull-down resistor Rpd is connected to the input port side. Of these, the functional switches 3c and 3d are connected to IN3 and IN4 via an OR circuit 0R3 (same as OR circuit 2 and below) and OR4. In addition, the input port side outputs of the cursor switches 4a to 4d are also input to the 4-person ORI, and the output of the ORI is input to the T (clock) terminal of the FFI (flip-flop) and the ANDI (AND circuits 2 and below are the same). There is. CPUI is connected to the other input terminal of ANDl.

is “H”), and when any cursor switch is turned on (ORI is “H”), it is transmitted to OR4 and OR3. Also, the east terminal output of FFI is fed back to the D terminal.The T terminal is “ When the T terminal becomes "H", the state of the Q terminal and the ?2 terminal is determined by the state of the D terminal.In other words, when the T terminal becomes "H", if the D terminal is "H", the Q terminal becomes "H". '', the east terminal is "L", and if the D terminal is "L", the Q terminal is "L" and the terminal is "H" six times.In other words, the D terminal has the state of the Q terminal and ■ terminal at that time. An inverting signal is input.With such a connection, when any cursor switch is turned on in the tremolo control mode, the tremolo effect and chorus effect are turned on alternately.

Further, 0UTI of CPUl0 is connected to a rising pulse generation circuit, and when the tremolo control signal rises, a pulse of one crotter length is output to OR2. OR
The output of the tremolo switch 3C is input to the other input terminal of 2, and the output of OR2 is input to the R terminal of FFI. That is, when the tremolo control mode is set (OUTI rises to "H") or when the tremolo switch 3C is turned on, FFI is reset (the q terminal becomes "H"). - S of FFI
The output of the chorus switch 3d is input to the terminal. That is, when the chorus switch 3d is turned on, FFI is set (the Q terminal becomes "H"). With this connection, effects can be switched using the tremolo switch 3c and the chorus switch 3d even in the tremolo control mode.

Furthermore, LEDI (6d) and LED2 (6c) are connected to the output ports 0UT2 and 0UT3 of the CPUIO. When in tremolo mode, 0UT3 becomes "H3" and LED2 lights up, and when in chorus mode, it becomes "01".
JT2 becomes “H” and LEDl lights up.

FIG. 4 is a timing chart of the signals of each switch (I10 port), and FIG. 5 is a flow chart showing the operation of the CPU 10. The operation of the sound source device will be explained based on these figures.

FIG. 5(A) is a flowchart explaining the tremolo control mode on/off operation.

CPU10 has all function switches 3. The on/off status of cursor switch 4 is monitored. In this operation, it is monitored that the tremolo switch 3c, shift switch 3g, and cursor switch (any one of 4a to 4d) are turned on at the same time (nl-n6). If they are not turned on at the same time, it returns as is. If they are both on at the same time, proceed to nl to determine whether the current mode is the tremolo control mode. If the tremolo control mode is off, set 0UTI to “H” to turn it on.
If the remolo control mode is on, set 0UTI to “L” to turn it off (n9
). I will return after this.

FIG. 3B shows the operation when IN3 or IN4 becomes "H". Even when the other ports become "H", operations similar to those in this flowchart are executed, but in this embodiment, the explanation of the other operations will be omitted to simplify the explanation. IN3 and IN4 are “H” at n1ln12.

When IN4 becomes "H'", the process proceeds from n12 to n16, and it is determined whether the chorus mode is currently on. If it is on, turn off the chorus effect and set 0UT2 to “L3” to LE.
Turn off D6d (n17). On the other hand, if the chorus is off, the tremolo effect is turned off and 0UT3 is set to “L”.

). I will return after this.

In the timing chart in Figure 4, tremolo switch 3C
When turned on, "H" is input to IN3 of the CPU, and the tremolo effect is sent. At this time, 0tJT3 is “Hl”
Then, the LEDec lights up (tl). If you turn on shift switch 3g and cursor switch (LEFT switch 4C) while holding down tremolo switch 3C, the CPU
Enters tremolo control mode as determined by l0 (
n8:t2), the tremolo effect is enabled in this state. Next, when one of the cursor switches (UP switch 4a) is turned on, the Q output of FF1 is inverted, AND2 becomes "H", and "H" is input to IN4, which is the input terminal of chorus switch 3d. Ru. With this human power, CPUl0 stops the tremolo effect and activates the chorus effect (t3:n18), and again switches the cursor (LEFT switch 4c and RrGH).
T switch 4d (it is the same even if it is turned on twice))
When turned on, the FFI is inverted and the tremolo effect and chorus effect are switched (t4:n15). Furthermore, when the cursor switch (DOWN switch 4b) is turned on, it switches again (t5).

Also, when the chorus effect is enabled, the tremolo switch 3
The effect also changes when C is turned on (t6). Further, even if the chorus switch 3d is turned on when the tremolo effect is in effect, the effect is changed (tl). Furthermore, even if all the cursor switches 4a to 4d are turned on at the same time, the effects are changed in the same way (t8). Next, when the tremolo switch 3C, the cursor switch (RIG) (T switch 4d), and the shift switch 3g are turned on at the same time, the tremolo control mode is canceled at the discretion of CPtJlo (n9), and only the tremolo effect remains (t9). Next, tremolo switch 3c
Turning on also cancels the tremolo effect (t10)
.

In the above embodiment, the switching control by the cursor switch in the tremolo control mode was performed by a hard logic circuit using a logic operation circuit, but it is of course possible to convert the program into software and have the CPU 10 execute it. In addition, function control using a group of centrally arranged controls (cursor switches, etc.) is called tremolo.
