Description

[Detailed explanation of the idea]

This invention relates to an electronic musical instrument in which a plurality of control modes combining tones, effects, etc. can be selectively set. In conventionally proposed electronic musical instruments of this type, if the control mode is changed by a switch operation, the timbre of the musical tone and the effect also change, which may result in an undesirable musical situation. For example, if an effect such as vibrato that has been applied up to that point is no longer applied due to a change in tone color, the continuity of the song will be disrupted, which is undesirable. The purpose of this invention is to provide a new electronic musical instrument that can prevent such situations from occurring. The electronic musical instrument according to this invention is characterized by being able to appropriately hold control data regarding effects.Hereinafter, an embodiment shown in the accompanying drawings will be described in detail.

2A, 112B...112E in parallel to the preset selector 113, where a musical tone signal of a tone corresponding to a specific musical style specified by the musical style designation signal _TS1 is selected, and the PK musical tone is Sent as signal PS. Next, details of the musical style designation circuit 50 will be explained with reference to FIG. In the music style selection switch circuit 120, an organ music style selection switch _S1 , a jazz music style selection switch _S2 ,
Mood style selection switch _S3 , mood style selection switch _S4 , and piano style selection switch _S5 (these switches _S1 to _S5 consist of self-resetting pushbutton switches); _S1 ,
T _- flip-flops F ₁ , F ₂ , in which the state signals S 2 , S ₃ , S ₄ , S ₅ are respectively applied to the trigger input T;
F ₃ , F ₄ , F ₅ and these flip-flops F ₁ ,
OR gates O ₁ , O 2 , O 3 , which supply reset signals to the reset input terminals R of F ₂ , F ₃ , _{F 4} , F _{5 ,} respectively;
O ₄ and O ₅ are provided, and each OR gate receives a music style selection switch state signal other than that input to its associated flip-flop. For this reason _, flip-flops F ₁ to F ₅ do not respond when multiple of the style selection switches S ₁ to S ₅ are pressed at the same time;
When _S5 is pressed one by one, it responds and sends out a musical style selection signal corresponding to the pressed switch. That is, for example, when the organ style selection switch _S1 is turned on, the output Q of the flip-flop _F1 becomes "1", instructing the selection of the organ style, while the other flip-flops
_F2 - _F5 are reset by the output signals of OR gates _O2 - _O5 which input the state signal of switch _S1 .
At this time, the flip-flop _F1 continues to output Q="1" even if the switch _S1 returns to normal state.
Next, for example, to select a piano style, press switch S ₅ .
When turned on, the output Q of flip-flop _F5 becomes "1", instructing the selection of piano music style,
At the same time, other flip-flops including flip-flop _F1 are reset. in this way,
From the music style selection switch circuit 120, each time one music style selection switch is turned on, a music style selection signal is sent from the corresponding flip-flop. The NOR gate NG and RO gate _O6 provided on the output side of the music style selection switch circuit 120 are initial setting circuits that enable selection of a specific music style when no music style selection switch is turned on. It constitutes. Here, the organ music selection signal from the flip-flop _F1 and the output signal of the NOR gate NG are input to the OR gate _O6 .
Since the music style selection signals from F ₂ to F ₅ are input, when none of the music style selection switches from S ₁ to _{S 5} are turned on, the output of the NOR gate NG becomes "1". Then, the output of OR gate _O6 becomes "1", and a signal instructing selection of an organ style is sent out. The music style selection signal generated from the OR gate O ₆ or the flip-flops F ₂ to F ₅ as described above is as follows:
This constitutes the music style designation signal TS ₁ , and is
The signal is supplied to the sound generation circuit 20, the LK sound generation circuit 30, and the PK sound generation circuit 40, while the display lamp circuit 1
20A and the preset data storage circuit 121. The display lamp circuit 120A is a music style selection switch.
This is to selectively light up the song style indicator lamps placed on each of the push buttons S ₁ to _{S 5} , and each time the song style designation signal TS ₁ specifies a specific song style, It acts to light up the music style display lamp of the corresponding music style selection switch. The preset data storage circuit 121 consists of a read-only memory (ROM) that stores five sets of preset data for tremolo, volume, sustain, vibrato, and slow attack for each style of music. An example of the stored contents is shown in the following table. That's right.

【table】

[Table] In this table, a circle mark means that tremolo, sustain, vibrato, or slow attack is included and the volume is set to high, and a blank mark means that tremolo, sustain, vibrato, or slow attack is turned off and the volume is set to low. This means that the ◯ mark corresponds to the signal "1" and the blank corresponds to the signal "0". Then, such stored contents are read out for each music style in accordance with the music style designation signal TS ₁ and supplied to one input terminal of each of the exclusive OR gates EO ₁ to _{EO 12} . Each other input terminal of the exclusive OR gates EO ₁ to _{EO 12} is connected to each switch section of the control switch circuit 122.
Control signals are applied from CS ₁ to CS ₁₂ , respectively. The control switch circuit 122 includes a switch section CS ₁
- In addition to CS ₁₂ , it includes a brilliance switch part CS ₁₂ , and these switch parts CS ₁ to _{CS 13} are
As illustrated for CS ₁ , the state signal of the self-resetting pushbutton switch SW is transferred to a T-flip-flop.
It has a similar configuration in which it is supplied to TF to obtain a control signal. Therefore, each switch part CS ₁ ~
A control signal is generated from the CS ₁₃ so that when each push button switch SW is pressed once, it becomes "1", and when it is pressed once more, it becomes "0". The exclusive OR gates EO ₁ to EO ₁₂ are provided so that the contents of the preset data read out from the preset data storage circuit 121 can be modified by switch operations in the switch units CS ₁ to CS ₁₂ . EO ₁ is the tremolo effect specification signal for the UK section (U), EO ₂ is the tremolo effect specification signal for the LK section (L), EO ₃ is the tremolo first specification signal, and EO ₄ is the tremolo effect specification signal for the UK section (U). ) volume designation signal,
EO ₅ is the volume specification signal for the LK section (L), EO ₆ is the volume specification signal for the PK section (P), EO ₇ is the sustain specification signal for the UK section (U), and EO ₈ is the UK section ( U)
EO ₉ is the sustain long designation signal for the PK section (P), EO ₁₀ is the vibrato slow start designation signal, EO ₁₁ is the vibrato fast start designation signal, and EO ₁₂ is the slow attack designation signal. Each can be modified. Here, as an example of preset data modification,
The case of modifying the tremolo effect designation signal of the UK section will be explained. At present, a tremolo effect designation signal of "1" is supplied to one input terminal of the exclusive OR gate EO ₁ from the preset data storage circuit 121 (the tremolo effect designation signal TS ₁ selects organ style, jazz style, or mood). ), the switch part
In the initial state when the CS ₁ switch is not operated at all, the control signal from it is "0", so the output of EO ₁ is "1", which acts to specify the addition of a tremolo effect. Next, when the switch of switch part CS ₁ is turned on once, the control signal from there becomes "1", so the output of EO ₁ becomes "0",
Acts to specify non-addition of tremolo effect. Then, when the switch of the switch unit _CS1 is turned on one more time, the control signal from there becomes "0", so the output of _EO1 becomes "1", and the addition of the tremolo effect is designated. Such operations are similarly performed in other exclusive OR gates _EO2 to _EO12 . Therefore, by appropriately operating each of the switches CS ₁ to CS ₁₂ during a performance, it is possible to bring about subtle changes in the style of the performance, which is advantageous in terms of musical effects. By the way, the above-mentioned control switch circuit 122
Since each switch section has a flip-flop TF, the control state is maintained or stored, so when changing the style in the style selection switch circuit 120, the previous style is changed. Even if the control state is favorable, it may be unfavorable for the newly selected musical style. For example, if you want to change the style from an organ style to a JAZZ style, press the JAZZ style selection switch S ₂ .
In principle, at the time of turning on the exclusive OR gate EO1, the output signal of the exclusive OR gate _EO1 becomes "1" in accordance with the stored contents of the preset data storage circuit 121, thereby specifying the addition of the tremolo effect. However, since the flip-flop TF of the switch section _CS1 was set to specify non-addition of the tremolo effect in the organ style specification state before the switch _S2 was turned on, the output signal of the flip-flop TF was kept at "1". If this were the case, the output signal of the exclusive OR gate FO ₁ would be "0" instead of "1" when the JAZZ-like music style was selected by the switch _S2 , and the non-addition of the tremolo effect would be specified. In order to eliminate such inconvenience, the state signals of the style selection switches _{S1 to S5} are input to the reset input terminals R of the flip-flops TF of the respective switch units CS1 to _CS13 of the control switch circuit 122.
The output signal ER _{of the} OR gate _O7 is supplied, so that the control state of the control switch circuit 122 is set to the initial state (all outputs are It is designed to return to the "0" state). Therefore, the control switch circuit 122 can perform control operations based on the initial state each time a musical style is selected, making the control operations extremely easy to perform. The effect holding circuit 123 is an exclusive OR gate EO ₁
~Equipped to hold effect control data consisting of EO ₁₂ output signals, and exclusive
When the output signals of the RO gates EO ₁ to EO ₁₂ are respectively inputted, the circuits include latch circuits L ₁ to _{L 12} . Since the latch circuits _L1 to _L12 have the same configuration and operate in the same way, the configuration and operation of the latch circuit _L1 will be explained as a representative. In the latch circuit _L1 ,
AG ₁ receives the output signal of the exclusive OR gate EO ₁ and the signal obtained by inverting the control signal EH from the effect holding switch section 124 by the inverter IV.
AND gate, _AG2 is a second AND gate to which the control signal EH from the effect holding switch section 124 is supplied to one input terminal, and OG is the first and second AND gate.
OR with the output signals of gates AG ₁ and AG ₂ as inputs
The gate DF is a D-flip-flop which receives the output signal of the OR gate OG and is timed by the system clock φ.
The output signal of DF is supplied to the other input of the second AND gate _AG2 . Further, in the effect retaining switch section 124, the output signal of the effect retaining switch ES is supplied to the T-flip-flop EF, and the control signal EH is taken out from the flip-flop EF. Now, if the effect holding switch ES is not turned on and the control signal EH from it is "0", the output of inverter IV will be "1", so the first
AND gate AG ₁ becomes conductive. In this case exclusive OR
If the output signal of the gate _EO1 is "1", this "1" signal is supplied to the D-flip-flop DF via the first AND gate _AG1 and the OR gate OG, and from its output terminal, the clock φ is It is sent with a bit time delay. At this time, the second
AND gate _AG2 is non-conductive because control signal EH is "0". Next, when the effect retention switch ES is turned on and the control signal EH becomes "1", AND gates AG ₁ and AG ₂ are turned on in the opposite way to the previous time.
AG ₁ is non-conductive and AG ₂ is conductive. Therefore, the output signal of the exclusive OR gate EO ₁ is the output signal of the AND gate AG ₁
While the input to the latch circuit _L1 is blocked, the “1” signal previously sent from the D-flip-flop DF is passed through the AND gate _AG2 to the OR gate.
The signal is fed back from OG to the input side of the D-flip-flop DF, and thereafter stored cyclically in the circulation path of DF-AG ₂ -OG-DF. This memorized state continues until the effect retaining switch ES is turned on again and the control signal EH is set to "0". In this way, the latch circuit _L1 continues to output the output signal = "1" even if the output signal of the exclusive OR gate _EO1 becomes "0",
It functions to hold effect control data, and the other latch circuits _L2 to _L12 also function in the same manner. Each latch circuit that constitutes the effect holding circuit 123
The effect control data sent from L ₁ to _{L 12} constitutes a music style designation signal TS ₂ and is supplied to the above-mentioned UK sound generation circuit 20, LK sound generation circuit 30, and PK sound generation circuit 40, Indicator lamp circuit 122A

Each time you specify a specific style, the switch section controls the control status of tremolo, volume, sustain, vibrato, slow attack, hold, etc. for that style.
The corresponding indicator lamps of CS ₁ to CS ₁₃ act to provide visual indication. Note that the effect retaining switch section 12
The control signal ES from 4 is supplied to the display circuit 124A for lighting and driving the effect retention indicator lamp provided on the push button part of the effect retention switch ES, and the effect retention lamp is turned on when the control signal EH reaches the "1" level. to indicate that effect control data is retained. FIG. 5 shows another embodiment of the effect holding circuit section, in which the same parts as in FIG. 4 are given the same reference numerals. The embodiment shown in FIG. 5 is characterized by effect holding circuits 123A, 123B, 123C, effect holding switch section 124a, 124b, 124c
,, effect retention display circuits 124Aa, 124Ab,
124Ac and inverters IV ₁ , IV ₂ , and IV ₃ corresponding to LK, LK, and PK, respectively. In this way, the effect control data of one or more of UK, LK, and PK can be appropriately held, which has the advantage of providing a wider variety of control modes. According to the above-mentioned electronic musical instrument of this invention, it is possible to enjoy a variety of performances, for example, in the following manner. In other words, when you first turn on the power,
An organ music style selection signal is sent from the OR gate O ₆ by the action of the NOR gate NG, and control modes such as timbre, volume, effect, etc. are automatically set in accordance with the organ music style. Next, when the music style selection switch _S2 is turned on to select a JAZZ style music style, control modes such as timbre, volume, effects, etc. are automatically set accordingly. In this case, preset data storage circuit 1
21, preset data as shown in the "JAZZ" section of the table above is read out.
If it is desired to modify this preset data, the desired control switch in the control switch circuit 122 may be operated. Then, when changing the music style from Jiyaz style to Mood style, if you want to retain the effect control data, turn on the effect retention switch ES. In this way, the exclusive OR gate
Since the effect control data consisting of the output signals EO ₁ to EO ₁₂ (that is, preset data from the memory circuit 121 or data modified by the control switch) is held in the effect holding circuit 123, the mood-like effect is maintained. When the selection switch _S3 is turned on, the style designation signal _TS1 specifies the tone control mode corresponding to the mood style, but the effect retention circuit 1
The music designation signal TS ₂ consisting of 21 output signals specifies the control mode of volume and effect corresponding to the previous JAZZ-like music. Therefore, it is possible to perform with a mood-like timbre and a jazz-like sound volume and effect. After this, if the volume and effects no longer play in a moody manner, the effect holding switch ES can be turned on once more to cancel the effect holding operation. As described above, according to this invention, a means is provided to hold control data such as effects separately from the timbre, so control modes for timbre, volume, effects, etc. are richer, and the connection between songs is broken. It is possible to prevent situations from occurring.
