BACKGROUND OF THE INVENTION
The present invention relates to an electronic musical instrument that reproduces a musical tone corresponding to an operated operator.
[0002]
[Prior art]
Conventionally, an electronic musical instrument that has an operation panel in which a plurality of operators assigned to each tone color is arranged, and reproduces musical tones associated with the operated operator among the plurality of operators. It has been known.
[0003]
FIG. 1 is a front view of a rhythm machine which is an example of such an electronic musical instrument, and a diagram illustrating an operation on the rhythm machine.
[0004]
The rhythm machine 1 shown in FIG. 1 reproduces musical sounds simulating various musical sounds generated from an acoustic drum set by operating an operation pad provided on an operation panel.
[0005]
The operation panel 2 of the rhythm machine 1 includes operation pads CRASH1, CRASH2, BELL, RIDE, TOM1, TOM2, TOM3, TOM4, CROSS STICK, CLAP, COWBELL, KICK, SNARE, PEDAL HIHAT, OPEN HIHAT, and CLOSED HIHAT. These operation pads form an operation pad group 2a.
[0006]
When the operation pads CRASH1 and CRASH2 are operated, two types of crash sounds are generated, and when the operation pads BELL and RIDE are operated, a bell sound and a ride sound are generated. In addition, when the operation pads CROSS STICK, CLAP, COWBELL, KICK, and SNARE are operated, a cross stick sound, a crap sound, a cowbell sound, a kick sound, and a snare sound are generated, and the operation pads TOM1, TOM2, TOM3, and TOM4 are operated. When this is done, four types of tom sounds are generated. When the operation pads PEDAL HIHAT, OPEN HIHAT, and CLOSED HIHAT are operated, a pedal hi-hat sound, an open hi-hat sound, and a closed hi-hat sound are generated.
[0007]
The operation panel 2 of the rhythm machine 1 is also provided with a volume knob 2b for controlling the volume, another operation switch group 2c, and an LCD (liquid crystal) display device 2d for displaying the volume level. Yes.
[0008]
FIG. 1 shows a state in which one operation pad (SNARE) provided on the operation panel 2 is operated by fingers of both hands. In this operation, the operation surface of the operation pad is alternately pressed with two fingers, and by quickly performing this operation, a musical sound assigned to the operation pad can be generated at a fast tempo.
[0009]
[Problems to be solved by the invention]
However, if this operation is performed on an operation pad having a narrow operation surface, there is a risk that the number of erroneous operations on the operation pad due to interference between fingers increases as the speed of the operation increases.
[0010]
Therefore, it is conceivable to make the operation surface of each operation pad as wide as possible. However, if the operation surface of the operation pad is unnecessarily widened, the outside size of the electronic musical instrument is increased.
[0011]
In view of the above circumstances, an object of the present invention is to provide an electronic musical instrument with improved operability while suppressing an increase in size.
[0012]
[Means for Solving the Problems]
To achieve the above object, an electronic musical instrument of the present invention is
Multiple main controls, each assigned a tone,
At least one sub-operator disposed in the vicinity of the plurality of main operators;
When any one of the plurality of main operators is operated, an instruction is given to play the musical tone assigned to the main operator, and the main operator operated immediately before the sub operator is operated. And a tone reproduction instruction means for instructing to reproduce a tone having a tone color associated with the tone.
[0013]
The electronic musical instrument of the present invention is provided with a sub-operator that assigns a timbre corresponding to the timbre associated with the operated main operator each time the main operator is operated. As a result, in the electronic musical instrument of the present invention, the sub-operator provided separately from the main operator can be used as if the main operator had been operated. Every time an operation is performed, the timbre corresponding to the timbre associated with each operated main controller is allotted to this sub-operator, so compared with the case where the operation surface of each main controller is simply enlarged, Can also be suppressed.
[0014]
Here, it is preferable that at least one of the sub-operators be arranged on the left and right of the main operator group including the plurality of main operators.
[0015]
In this way, when the main operator is operated with the right hand, the sub-operator provided on the left side of the main operator is operated with the left hand, and when the main operator is operated with the left hand, the main operator is operated with the right hand. This is convenient because the sub-operator provided on the right side of the operator can be operated.
[0016]
Further, the tone reproduction instruction means instructs the sub-operator to reproduce a tone having the same or a variation of the tone assigned to the main operator operated immediately before the plurality of main operators. You may do.
[0017]
This makes it possible to perform with a rich tone.
[0018]

The details of the operation of the rhythm machine 10 of this embodiment will be described below with reference to FIGS. 4 and 5.
First, in the rhythm machine 10, when a power switch of the rhythm machine 10 (not shown) is turned on and an operation on either the main pad or the sub pad is detected, in step S1, the operation on the operation panel 20 is for the sub pad. It is determined whether or not.
[0032]
If it is determined in step S1 that the operation on the rhythm machine 10 is on the main pad, the process proceeds to step S2.
[0033]
In step S2, the main pad number, which is the identification number of the operated main pad, is used as an address argument, and the timbre number stored in the corresponding address is acquired. Thereafter, the process proceeds to step S3.
[0034]
Here, FIG. 5 (a) is a Main Pad tone color map table showing Main Pad numbers and tone color numbers.
[0035]
FIG. 5 (a) shows a state in which a timbre number is assigned to an address having a Main Pad number as an argument. For example, when the main pad whose main pad number is “01” is operated, the timbre number “009” is acquired using the main pad number “01” as an argument.
[0036]
In step S3, the Sub Pad tone color map address stored in the address having the tone number obtained in step S2 as an argument is acquired. Thereafter, the process proceeds to step S4.
[0037]
Here, FIG. 5B is a Sub Pad timbre map address map table indicating the timbre number acquired in step S2 and the Sub Pad timbre map address.
[0038]
FIG. 5B shows a state in which the Sub Pad tone color map address is associated with the address having the tone number obtained in step S2 as an argument. For example, when the timbre number acquired in step S2 is “009”, the Sub Pad timbre map address “spm002” is acquired from the address having the timbre number “009” as an argument.
[0039]
In Step S4, the Sub Pad tone color map address acquired in Step S3 is stored in the Sub Pad tone color instruction memory area provided in the RAM 60 shown in FIG. Then, it progresses to step S7.
[0040]
In step S7, the tone of the musical tone represented by the musical tone data read out based on the timbre number acquired in step S2 is performed using the Main Pad number of the operated main pad as an argument.
[0041]
Here, when it is determined in step S1 that the operation is for the subpad, the description will be returned.
[0042]
In this case, the process proceeds to step S5, in order to acquire the tone number of the tone assigned to this subpad according to the tone associated with the last operated main pad before the operation on this subpad. Then, the Sub Pad tone color map address is acquired from the Sub Pad tone color instruction memory area provided in the RAM 60 shown in FIG. Then, it progresses to step S6.
[0043]
In step S6, the timbre number assigned to this subpad is acquired from the Sub Pad timbre map address obtained in step S5 and the Sub Pad number of the operated subpad.
[0044]
Here, FIG. 5C is a Sub Pad timbre map table showing the Sub Pad timbre map address, Sub Pad number, and timbre number.
[0045]
In the Sub Pad tone color map table shown in FIG. 5 (c), the tone numbers are assigned to the four subpads, as shown in the four sub pad numbers "0", "1", "2", and "3". Sub Pad numbers “0”, “1”, “2”, and “3” correspond to the subpads SUB1, SUB2, SUB3, and SUB4 shown in FIG.
[0046]
FIG. 5C shows a state in which a timbre number is associated with an address having a combination of a Sub Pad timbre map address and a Sub Pad number as an argument. Therefore, for example, when the sub pad SUB1 (Sub Pad number “0”) is operated while the Sub Pad tone color map address “spm002” is stored in the Sub Pad tone color instruction memory area, the tone number “010” When SUB2 (Sub Pad number “1”) is operated, the timbre number “012” is selected. When Subpad SUB3 (Sub Pad number “2”) is operated, the timbre number “011” is displayed, and the subpad SUB4 (Sub Pad number “1”). 3)) is operated, the timbre number “014” is acquired. Thereafter, the process proceeds to step S7, and the tone of the tone represented by the tone data read based on the tone color number acquired in step S6 is performed, and this routine ends. The tables shown in FIGS. 5A to 5C are stored in the ROM 70 shown in FIG. 3 in this embodiment, but these various tables are stored in the RAM 60 and can be rewritten by the user. It may be.
[0047]
In the rhythm machine 10 of the present embodiment described above, when one of the main pads is operated, the tone of the timbre associated with the operated main pad is generated and associated with the operated main pad. The timbre variation timbres assigned are assigned to the sub pads SUB1, SUB2, SUB3, and SUB4 arranged on the left and right of the main pad group.
[0048]
Further, when any of the sub pads SUB1, SUB2, SUB3, and SUB4 is operated without operating the main pad, any one of the tone colors of the timbre associated with the last operated main pad is selected. Pronounced. Therefore, according to the rhythm machine 10 of the present embodiment, the operability can be improved without increasing the size of the operation panel, and the operated main pad can be operated by operating the sub pad while operating the main pad. Play the musical tone of the tone associated with the pad and the musical tone of the variation of the tone associated with the operated main pad, and give the musical tone of the tone associated with the operated main pad wide Can do.
[0049]
Here, the variation timbres assigned to these subpads SUB1, SUB2, SUB3, and SUB4 are not fixed and may be randomly assigned from within a limited timbre group.
[0050]
In the present embodiment, two subpads are provided on each of the left and right sides of the main pad group, and tone variations corresponding to the last operated main pad are assigned to these four subpads. However, the present invention is not limited to this, and there is one variation timbre associated with the last operated main pad, or the same timbre associated with the last operated main pad, one on each of the left and right sides. May be assigned to subpads that are deployed one by one, or the same tone as the tone associated with the last operated main pad, or the tone associated with the last operated main pad. A variation tone is assigned to one subpad that is placed on one of the operation panels. Good. Furthermore, the timbres assigned to these four subpads may all be the same timbre as the timbre associated with the last operated main pad.
[0051]
Further, in the present embodiment, the description has been given by taking as an example a case in which musical sounds simulating various musical sounds generated from an acoustic drum set are reproduced in accordance with an operation on the operation pad. Other than the above, a pad is taken as an example of the operation element, but a normal operation button, a screen switch on the LCD, or a keyboard may be adopted as the operation element. .
[0052]
Here, it can be considered that the rhythm machine 10 of the present embodiment has the following functions.
