Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a group performance training device in which electronic musical instruments, particularly electronic musical instruments equipped with a voltage-controlled musical tone synthesis system, are arranged in a master unit and each slave unit.

This type of group performance training device is well known, but in the conventional device, for example, when performing an ensemble performance, each electronic instrument on the child device side is controlled based on verbal instructions from the parent device. Since the switches and volumes for musical sound control are set separately and independently, the settings of these switches and volumes are not unified among each electronic musical instrument, making it difficult to perform harmonious and effective ensemble performances. there were. Furthermore, since the slave unit sets the tone control switch or volume based on verbal instructions from the parent unit, the operation thereof requires a considerable amount of time and effort. An object of the present invention is to provide a new group performance training device that eliminates this type of drawback.

The gist of this invention is to transmit the setting status of the tone control switch or volume controller on the electronic musical instrument of the base unit to each slave unit and display the setting status of the tone control switch or volume controller. The main feature is that the corresponding musical tone control operator can be adjusted to match the settings of the operator on the machine side. In this way, for a large number of slave units, it is possible to easily and quickly set the controllers in a uniform manner based on the settings of the controllers on the parent unit, which greatly improves training efficiency. This has the advantage of significantly reducing the time and effort required to operate the set state arm, especially during ensemble performances. Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows a group performance training device according to an embodiment of the present invention, which includes a base unit and a number of slave units connected to the base unit for communicating with each other regarding performance lessons. It has the following.

To simplify the explanation, FIG. 1 omits illustration of a communication system for communication regarding performance training between the parent device and each child device. An electronic musical instrument equipped with a voltage-controlled musical tone synthesis system is placed on the main unit side, and this electronic musical instrument is turned on every time a specific key switch out of a large number of keyswitches is turned on. A key switch circuit 10 that generates a tone pitch voltage KV corresponding to the key switch that has been turned on and also generates a key-on signal KON indicating the existence of the on operation, and a voltage control type key switch circuit 10 that controls the oscillation frequency according to the tone pitch voltage KV. A tone source oscillator (VCO) 12, a voltage-controlled timbre filter (VCF) 14 that imparts desired timbre characteristics to the sound wave signal from the VCO, and a voltage-controlled timbre filter (VCF) 14 that adds an appropriate amplitude envelope to the musical tone signal from the VCF. It includes an amplifier (VCA) 16, an output amplifier 18 for amplifying the musical tone signal output of the VCA, and a speaker 20 driven by the output of the power amplifier. The base unit of the electronic musical instrument is also provided with a setting level signal generation circuit 22 including variable resistors VR, ~VR, o for voltage level setting in order to set musical tone elements, and the setting level signal from this circuit is ,, 2 is the envelope generation circuit (EG) 2
4 and 26, respectively. Here, the set level signals are initial level IL, attack level AL
, attack time AT, first decay time lOT, and second decay time T are respectively taken out from a group of variable resistors VR, ~VR5 in the form of a voltage signal according to the setting state of the mover. , and the setting level signal 2 is a group of variable resistors VR6 to VR, which variably set the attack level AL, attack time AT, first decay time IDT, sustain level SL, and second decay time T, respectively. , and is extracted in the form of a voltage signal according to the setting state of the movable element.
The envelope generation circuits 24 and 26 generate a key-on signal KO.
Each time N indicates that the key switch has been turned on, the setting level signal input to each circuit 24, 26 is set to an envelope signal Vc based on LS2, for example, using charging and discharging of a capacitor. , , v, respectively, and these envelope signals Vc, , Vc2 are supplied to the VCF 14 and VCA 16, respectively. VCF1
4 gives a subtle change to the timbre characteristics of the old source signal from the VCO 12 by changing its frequency characteristics according to the envelope signal Vc, and the VCA 16 changes its gain according to the envelope signal Vc2. , V
An amplitude envelope is given to the musical tone signal from the CF 14. Note that the pitch voltage KV is applied to the VCF 14 via a variable attenuation resistor 28, and the VCF 14 is controlled so that its cutoff frequency increases as the pitch increases. The voltage-controlled electronic musical instrument as outlined above is now called a music synthesizer and is known per se (for example, see Hakamakai No. 49-129519), so a more detailed explanation can be found at: Omit this. Now, according to the teachings of the present invention, in the above-mentioned parent electronic musical instrument, a variable resistor V for variably setting several conditions for determining the timbre characteristics and amplitude envelope characteristics of musical tones is provided.
The setting states of R, to VR, o are transmitted to the handset side via the signal distribution circuit 30 and displayed as described below.

In this embodiment, the set level signal is . Since LS2 itself indicates the setting state of each variable resistor, it is detected as a setting state signal, and gate groups 30A, 30B, 30C, . . . corresponding to each slave unit in the signal distribution circuit 30 are detected.
... are supplied in parallel. Each gate group 30A,
In 308, 30C......, 10 gates equal to the total of the set level signal and LS2 are arranged in parallel, and each gate group has a corresponding one. Handset selection switch 32A, 328, 32C・
A control signal is supplied from... Handset selection switch 32A, 32B, 32C...
When any of the movable contacts is turned on to the "1" signal source side, the corresponding gate group becomes ready for signal transmission, and the setting state signal (i.e., in this example, the setting level signal is LS2) to the corresponding slave device. “0”
Since the gate group corresponding to the handset selection switch whose movable contact is closed to the signal line side is in a signal transmission disabled state, no setting state signal is transmitted to the handset side in this case. On the handset side, there are many handsets 40A, 40B, 4
0C......... is arranged, and the valley child unit is provided with a voltage-controlled electronic musical instrument and a setting state display means to illustrate a typical configuration for the child unit 40A. There is.

Here, the voltage-controlled electronic musical instrument has a key switch circuit 50.

It works the same way. The features of this slave electronic musical instrument are the setting level signals LS, . , LS,2, a variable resistor VR, . In correspondence with ~VR, the setting states of the variable resistors VR, ~VR, o on the parent device side can be visually displayed. This is connected to variable resistor VR, . To explain specifically, each variable resistor VR, . Light emitting elements 0, , D2 are attached near the movable element of ~VR2o, and the output of the display signal forming comparison circuit COM is supplied to these light emitting elements ○, , D2 via resistors R, , R2, respectively. The positive input device of the comparison circuit COM includes the variable resistor VR. of the parent device. A setting state signal V, which indicates the setting state of At the ends are variable resistors VR, . A voltage y2 of the movable element is applied. Now, assuming that the comparison inputs V, , V2 are in the relationship V,>V2, the comparison circuit COM generates a positive voltage output, and the light emitting element D lights up. On the contrary, V.
If <V2, a negative voltage output is generated and the light emitting element D2 lights up. Furthermore, if it is V3V2, it is almost 0 [V
], and none of the light emitting elements lights up. Therefore, the student of slave unit 40A uses variable resistors VR, . By adjusting the movable element, it is possible to easily reach a setting state similar to that of the variable resistor VR of the parent unit. Therefore, the envelope generation circuits 64 and 66 output the envelope signals Vc·, Vc on the base unit side.
Envelope signals Vc, . , V female, it is possible to generate musical tones with the same timbre characteristics as those on the parent unit side. The display of the setting state of the variable resistor described above and the adjustment of the variable resistor based on the display are exactly the same for the other variable resistors VR, 2 to VR2o. As described above, according to the present invention, on the handset side, each variable resistor VR, .
~ By adjusting the movable element of VR2o, it is possible to easily reach the same setting state as the parent unit, so the variable resistance adjustment operation on the electronic musical instrument of each slave unit can be completed easily and in a short time, making it easier to play. The time that can be devoted to teaching will increase, and teaching efficiency will be greatly improved.

Furthermore, when performing an ensemble performance, the variable resistance can be uniformly set among multiple slave units to match the settings of the parent unit, allowing harmonious and effective ensemble performances. It can be carried out. Next, another embodiment of the present invention will be described with reference to FIG.

The group performance training device of this embodiment converts a setting status signal into a digital signal and temporarily stores it in a storage device, and then outputs the stored contents from this storage device as appropriate and distributes them to each slave electronic musical instrument. It is distinctive in that it is supplied. That is, on the base unit side, a setting level signal is detected as a setting state signal from the setting level signal generation circuit 70, and this setting state signal is supplied to the A/D converter 74 via the multiplexer 72, where it is converted into a digital signal. converted.
This digitized configuration state signal is written to random access memory (RAM) 76. Here, R
Since the AM76 has memory channels 1 to n corresponding to n (n is any integer) timbre categories, when writing the digitization setting state signal, select the channel selection switch S of the control circuit 78. After selecting the storage channel, the write command switch S2 is turned on. In this way, the RAM 76 can store n sets (corresponding to n tones) of combinations of different setting states of the plurality of variable resistors in the setting level signal generating circuit 70. The memory contents of the RAM 76 can be changed to the external memory IJ8 by turning on the external storage command switch S3 as appropriate.
It can also be transferred to 0 and stored there. As the external memory 80, a suitable magnetic card type storage bag can be used. Note that by turning on the import command switch S4 as appropriate, the stored contents of the external memory 80 can be changed to R.
It can also be imported into AM76. Now, the digitization setting state signal stored in the RAM 76 as described above is as follows.
By operating the channel selection switch S and output command switch S5, each tone color category is read out and transmitted to the handset side.

When transmitting the digitization setting state signal to the handset side, the handset 140A, 1 is selected in advance by the handset selection switch S6.
A specific child device among 408...... is selected. The switching position output of the slave device selection switch S6 is converted into a binary code signal A by the encoder 82 and sent to each slave device. Here, taking the slave unit 140A as an example, the circuit system for reproducing the setting state in each slave unit will be explained.
It is compared with a predetermined handset code signal B in a comparison circuit 84, and when the two match, a match signal EQ is sent to a control circuit 86. When control circuit 86 receives this match signal EQ, it activates demultiplexer/sample hold circuit 90. The digitized setting status signal sent from the RAM 76 is converted into a corresponding analog signal by the D/A converter 88, and this analog signal is sent to each variable resistor (
VR in Figure 1, . - Compatible with VR2o)
It is held by the sample and hold circuit 90. Therefore, the variable resistors VR, . Regarding the variable resistor corresponding to , the setting state signal V is reproduced, and the setting state is displayed in accordance with the setting state signal V, and the variable resistor is adjusted based on the setting state signal V, as described in detail with respect to FIG. As described above, according to the embodiment shown in FIG. 2, in addition to the effects obtained in the case shown in FIG. This has the advantage of reducing the burden on teachers.

In other words, all you need to do is to store the setting state settings and combinations for n tones, read them out as appropriate, and transmit them to the handset, and as in the case of Figure 1, each time you change the tones, you can change the settings of the variable resistor group. There is no hassle of having to change the settings. FIG. 3 shows a modification of the setting status display means on the handset side, in which setting status signals V, sent from the base unit,
is converted into a corresponding digital signal by the A/D converter 92.

According to such a configuration, the setting status on the parent unit side is displayed by lighting one of the light emitting elements, and the slave unit adjusts the movable element of the variable resistor according to the display, and when the setting status matches, By turning off the light emitting element, the setting state adjustment operation on the handset side can be greatly simplified. In particular, the display means shown in FIG. 3 is advantageous in that it allows fine adjustment of setting conditions. Although this invention has been described above in detail with reference to several embodiments, this invention is not limited to the above embodiments and can be implemented in various modified forms.

For example, in the examples shown in Figures 1 and 3, the light-emitting element is dimmed when the settings match between the master unit and slave unit. Various display methods can be considered, such as lighting. Also,
In the examples shown in FIGS. 1 and 2, the setting state signal is supplied to each slave unit, but the signal may be supplied to each slave unit group. Furthermore, in the above example, the setting state of the variable resistor (polyum) was transmitted to the handset side, but this is not limited to the setting of switches such as a cut-off switch that controls the addition or non-addition of the vibrato effect and other effects. Status can also be transmitted. Furthermore, it is not always necessary to use a setting level signal as the setting state signal, and this may be generated separately.
