Description

[Detailed explanation of the invention] This invention provides a mixer device for each player, allows each player to create their own performance sound according to their own preference, and then allows each player to adjust the created performance sound according to his or her own preference. The present invention relates to a group performance device that allows mixing to be heard at a high volume.

Various types of group performance devices have been proposed in the past, but in all devices, the signals from each musical tone signal generation source are mixed and controlled via a common mixer device, so the final group performance The form of the performance sound is left to the mixing operator's preference, and individual players cannot hear the collective performance sound in their preferred form.

Furthermore, in order to enable each player to listen with different mixing balances, the apparatus becomes large-scale.

This idea was devised in view of the above-mentioned problem, and its purpose is to allow each player to create their own performance sound according to their own preferences, and then to allow each player to create their own performance sound according to their own preferences. The purpose is to allow mixing to be heard at a volume appropriate for the user.

In order to achieve the above purpose, this invention places a mixer device at each player's hand, allows each player to create his or her own performance sound according to his or her own taste, and then allows the player and other players to create their own performance sounds. This allows users to mix the performance sounds at a volume that suits their taste.

A preferred embodiment of this invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the electrical configuration of the collective performance device according to the invention, and FIG. 2 is an explanatory diagram showing the state of use of the device.

In FIG. 1, A to C indicate mixer devices, and these mixer devices are arranged near each of the players 1 to 3 as shown in FIG.

Each mixer device A, B, C is provided with four sets of input terminals and two sets of external lead-out terminals. The first input terminals IN・A to IN・C are for inputting musical sound signals from the instruments of the corresponding players 1, 2, and 3, respectively. However, a bass guitar 5 is connected to the input terminals IN/B, and a vocal microphone 6 is connected to the input terminals IN/C.

The first external terminals OUT・A~OUT・C output the musical tone signals supplied to the first input terminals IN・A~IN・C to the tone control circuits TC・A~
This is for outputting after adjusting the tone through TC and C respectively, and these external lead-out terminals
OUT・A~OUT・C are the corresponding second and third input terminals of other mixer devices except the concerned mixer device.

A″, and the external lead-out terminal OUT・B of mixer device B is connected to the second input terminal IN・B′ of mixer device A and the third input terminal IN・B″ of mixer device C. Furthermore, the external lead-out terminal OUT·C of the mixer device C is connected to the third input terminal IN·C′ of the mixer device A and the third input terminal IN·C″ of the mixer device B. The fourth input terminals IN・D1 to IN・D3 are connected to tape recorders 7 on which other musical instrument sounds, etc. are recorded.
connected to.

Next, in each mixer device A, B, C,
Each tone control circuit TC・A, TC・B,
The musical tone signals supplied to the output of TC.C and the second and third input terminals are supplied in parallel to the mixing circuit 8.

The mixing circuit 8 is composed of three volumes VR ₁ , VR ₂ , VR ₃ that individually control the level of each musical tone signal, and these volumes VR ₁ ,
The respective outputs of VR ₂ and VR ₃ are collectively combined and supplied to the sound field creation circuit 9.

The sound field creation circuit 9 branches the above-mentioned synthetic tone signal into three signal lines _S1 to _S3 as shown in the figure, with the line _S1 being directly supplied to the left mixing amplifier _10L and the line _S3 being directly supplied to the right mixing amplifier _10R . The line _S2 is delayed for a predetermined time via a bucket brigade device (hereinafter referred to as BBD) 11 and then branched into two signal lines _S4 and _S5 . The line _S4 is supplied to the left mixing amplifier _10L , and the line _S5 is supplied to the right mixing amplifier _10R after being phase-inverted by 180 degrees via an inverter circuit 12.

Thus, the left and right mixing amplifiers 10 _L , 1
_0R , the synthesized musical tone signal output from the mixing circuit 8 is combined with a delayed signal having a certain time delay and is supplied while overlapping.
This results in an echo effect.

In addition, the playback signal (fourth musical tone signal) from the tape recorder 7 supplied to the fourth input terminals IN・D1 to IN・D3 has a different volume for the L and R signals.
After adjusting the volume level via VR ₄ and VR ₅ ,
It is supplied to left and right mixing amplifiers _10L and _10R .

And left and right mixing amplifiers _10L , _10R
The output is the external lead-out terminal OUT(L) for monitoring,
The signal is supplied to OUT(R), and the headphone 13 is driven by this output.

In the above configuration, for example, as shown in FIG. 2, a group performance is performed by three players 1, 2, and 3, including a lead guitar 4, a bass guitar 5, vocals, and the sounds of other musical instruments recorded on a tape recorder 7. When doing this, first each player 1, 2,
3 sets the headphone 13 respectively.

Next, when the group performance starts, the musical tone signals generated from each musical tone signal generation source (in this case, lead guitar 4, bass guitar 5, microphone 6) are sent to the corresponding tone control circuits TC・A~
After the tone is adjusted by TC・C, each mixer device A,
It is supplied in parallel to the B and C mixing circuits 8,
Furthermore, musical tone signals from the tape recorder 7 are supplied to volumes VR ₄ and VR ₅ .

Therefore, in this state, each player 1, 2,
3 is each volume VR ₁ of each mixer device A, B, C
~ When VR ₅ is operated, a collective performance sound with a mixing mode corresponding to the operation status of each volume VR ₁ ~ _{VR 5} will flow out from each headphone 13 with an appropriate echo effect. You can listen to the collective performance sound mixed according to your preference.

In this way, the collective performance device according to this embodiment is provided with three mixer devices A, B, and C corresponding to each of the players 1, 2, and 3, and each mixer device A, B, and C has its own and Multiple input terminals IN・A~IN・C,IN・corresponding to other players respectively
A'~IN・C', IN・A''~IN・C'', and the tone control circuit TC that adjusts the tone of the musical tone signals supplied to the personal input terminals IN・A~IN・C.
A to TC・C and the tone control circuit
External output terminals OUT・A～OUT・C for mixing to derive the output of TC・A～TC・C to the outside.
and the tone control circuit TC・A~TC・
The musical tone signal output from C and the input terminals IN・A′~IN・C′, IN・A″~ for each of the other players mentioned above.
A mixing circuit 8 is provided to suitably mix the musical tone signal supplied to IN・C'', and the output of this mixing circuit 8 is amplified to drive the headphone 13. By appropriately operating each volume VR ₁ to VR ₃ of A, B, and C, each player 1, 2, and 3 can create their own performance sound according to their own preferences, and then the performance sound created by each player. You can listen to the mix at a volume that suits your tastes.

Furthermore, according to this embodiment, the output of the mixer circuit is amplified via a sound field creation circuit using a BBD, so a sufficient sound spread can be obtained with a simple circuit configuration, and performance effects can be improved. can be significantly expanded.

As is clear from the explanation of the embodiments above, according to this invention, each player creates his or her own performance sound according to his or her own preference, and then each player can create the performance sound created by each player according to his or her own preference. The mixing can be heard at a high volume, and the circuit configuration is simple and can be manufactured at low cost, contributing to the widespread use of this type of group performance device to the general public.
