Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a preset information selection device for an electronic stringed instrument. The present invention relates to a preset information selection device for an electronic stringed instrument.

[Conventional technology]

Generally, when playing a piece of music using an electronic stringed instrument that does not have its own sound generating device, such as an electric guitar, the player's string picking (playing operation) is performed externally to the electronic stringed instrument. Accordingly, it is necessary to add various effects (musical sound effects) to the musical sound signal output from the electronic stringed instrument, and to emit the musical sound signal after amplifying the musical sound signal to which the effects have been added to a predetermined level.

FIG. 5 is a diagram showing the system required to operate a conventional electric link guitar.

As shown in the figure, the conventional system includes an effector system 2 that adds various effects to the musical sound signal output from an electric guitar 1;
The system 2 includes a foot controller 3 which specifies the type of effect to be added to the musical tone signal by the performer's foot operation, and a foot controller 3 which controls the musical tone signal to which various effects have been added by the effector system 2 to a predetermined rail. A guitar amplifier 4 (including a speaker (not shown)) is required to amplify the signal to a maximum level and then emit the sound. In particular, the effector system 2 can selectively combine and add multiple types of effects such as chorus, delay, distortion, and reverb to the musical sound signal output from the electric link guitar 1. , and is configured to be able to store a plurality of setting states of the combined effects. The plurality of stored effect setting states can be automatically switched by the player's foot operation of a foot switch provided on the foot controller 3 that corresponds to the setting state.

Note that the musical sound signal output from the electric guitar 1 is obtained by a front pickup 5a and a rear pickup 5b that convert the vibration frequency of strings (not shown) that vibrate when the player picks (plays the strings) into electrical signals. It is something that can be done. The settings of the pickups 5a and 5b used for performance and the volume are manually performed by operating a pickup switch and volume control (not shown) provided on the panel of the electric guitar 1.

[Problems to be Solved by the Invention] By the way, when the front pickup 5a and rear pickup 5b mounted on the electric guitar 1 are selectively used, they generally change the vibration frequency of the string according to its tonal range. Therefore, it is necessary to use the effect added to the musical sound signal properly in order to maximize the characteristics of the effect and obtain a musical sound with a timbre that matches the player's taste.

FIG. 6 is a diagram showing an example of a combination of an effect added to a musical tone signal and a big amplifier to be used.

As shown in the figure, first, the effector system 2 has four types of effects to be added to the musical sound signal: chorus, delay, distortion, and reverb. If it is not added, write it as OFF).
．． 2.3 and 4 are stored in advance.

Then, it is predetermined that the performer selects the front pickup 5a in the above setting states 1 and 2, and selects the rear pickup 5b in the above setting states 3 and 4 (using the corresponding pickup). (Describe it as ON if it is used, and OFF if it is not used). Also, regarding the volume of musical tones emitted from the guitar amplifier 4, the performer can adjust the volume according to setting states 1, 2, 3, and 4.
It is assumed that "5", "4", "8" and "10" are to be set, respectively.

Here, consider a case where the performer switches the combination of effects stored in the effector system 2 from, for example, setting state 2 to setting state 3 while playing a piece of music.

In this case, the combination of effects is determined by the performer using the foot
The player can switch automatically by simply operating the foot of the controller 3, but the performer can select the pickup and adjust the volume by using the pickup switch provided corresponding to each pickup 5a and 5b and the volume adjustment volume. Had to operate it manually. That is, the performer switches the effect by stepping on the foot switch corresponding to setting state 3 of the foot controller 3, and at the same time operates the pickup switch to turn the front pickup 5a from ON to OFF. While switching the rear pickup 5b from OFF to ON,
It was necessary to operate the volume control and instantly switch the setting value from "4" to "8". However, it is extremely difficult for a performer to perform these various switching operations instantaneously and at appropriate timing during a performance, which poses a problem in the performance of a musical piece.

Furthermore, the setting switch is composed of, for example, a 4-contact type slide switch, and there are 4 types of setting numbers (combinations of the type of pickup to be used and the volume adjustment value) depending on the number of contacts. This is for switching and selecting the Furthermore, the switches PUI and PO2 are comprised of bushing switches and the like, and the front pickup 12a and rear pickup 12b are selected, respectively, in response to a pressing operation (on operation) of the switches PUI and PO2. Further, the volume volume 20 is a sliding volume, and is used to control the volume of the VCA 23.

History - 11 Next, the operation of the electric guitar 11 having the above configuration will be explained.

First, a method of operating the electric guitar 11 described above will be explained using a specific example.

FIG. 3 is a diagram for explaining the operating method of the above embodiment.

In the SET mode, the electric guitar 11 stores in the RAM 1 the combinations (up to 4 types) of the pickup type and volume adjustment value to be used for the performance by the performer operating the corresponding switch in the switch group 27.
9, and in the PLAY mode, the performer performs the 77 operation of the corresponding foot switch of the controller 15 or the above-mentioned setting switch to write the pickup written to the RAM 19. A desired combination can be selected from a plurality of combinations of types and volume adjustment values.

As shown in the figure, in the SET mode (■ to ■),
When the performer operates the switches PUI, P U 2, and the volume volume 20, the switch PUI at that time,
The status of PO2 and the setting value of the volume volume 20 are detected by the CPU 17, and the CPtJ17 controls the states of the electronic switches ESWI, ESW2, and VCA23 to be equal to the settings of the switches PU1, PO2, and the volume volume 20. do. In other words, electric guitar 11 electronic switches ESWI, ES
The status (on/off state) of W2 is changed at any time under the control of the CPU 17 in accordance with the player's operation of the switches PUI and PO2.

The setting numbers specified by operating the setting switch are numbers corresponding to four combinations of pickup type and volume adjustment value that can be stored in the storage area in the RAM 17. be.

Therefore, in this example, four storage areas are secured in the RAM 17 corresponding to four types of setting numbers from "1" to "4".

Here, in the SET mode ■, the performer selects "3" as the setting number by operating the setting switch, and then presses the WRITE switch to enter the 0NLSET mode ■. ”
The switches PUI and PO in the above SET mode
The status (on/off state) of 2 and the set value of the volume 20 are written. That is, in the SET mode, by turning on the WRITE switch, the combination information of the pickup type and volume adjustment value is updated to the RA corresponding to the set setting number.
It is written to the storage area of M19. And WRITE
If you do not turn on the switch, the above combination information will be RA
M19 Otoko is not written (SET Mort ■~■).

On the other hand, in the PLAY mode, the foot switch corresponding to the setting number "3" of the foot controller 15 is operated, or the player operates the setting switch and the setting number "3" is set. 3" is selected, the switch PUI is selected from the storage area of the RAM 19 corresponding to the setting number "3".
and PO2 status and volume 20 setting value are read out, and based on the read status and setting value, on/off settings of electronic switches ESWI and ESW2 and control of VCA 23 are set as shown in PLAY mode ■. It will be held on.

Similarly, in the PLAY motes ■, ■, and ■, by performing the foot operation of the corresponding foot switch of the foot controller 15 similar to the above or the operation of the corresponding setting switch, the setting number "
Electronic switch ESWI compatible with 1, 2, and 4
, ESW2, and VCA23 are controlled.

Note that the CPU 17 determines whether the external control signal is input manually and whether the setting switch is operated. This is done prior to determining the operation.

Next, various setting control processes performed by the CPU 17 will be explained.

FIG. 4 is a flow chart for explaining the setting control processing performed by the CPU 17.

The electric link guitar 11 of this embodiment operates in either the SET mode or the PLAY mode, which is set by the player operating a mode switch in the switch group 27.

That is, when the performer operates the mode switch to make a mote setting, the CPU 17 determines whether the currently set mode is the SET mode or the PLAY mode (531), and determines whether the mode is the SET mode or not. In some cases, processing is performed to write the data of the pickup to be used and the volume adjustment value to the RAM 19, and the
In the LAY mode, processing for reading the above data from the RAM 19 is performed.

Below is the process and PLA when the mode is SET mode.
The processing in the Y mode will be explained in order.

First, in the above process 331, the current mode is set to SET.
mode, the CPU 17 detects the status of the switch PUI, and detects the status of the electronic switch ESW.
I is set to correspond to the detected status of switch PU1 (S32). Subsequently, the status of the switch PU2 is detected in the same way, and the electronic switch ESW is
2 is set to correspond to the status of switch PU2 (S33). Further, the CPU 17 reads the setting value of the volume volume 20 via the A/D converter 21, and sends the read volume volume 20 to the VCA 23.
The volume data corresponding to the setting value of 0 is sent to the D/A converter 2.
2 (S34).

That is, the CPU 17 sets each of the electronic switches ESWI and ESW2 to ON or OFF depending on whether each of the switches PUI and PU2 is set to ON or OFF, and also sets the volume volume 2.
The VCA 23 is controlled according to the set value of 0.

Next, after controlling the electronic switches ESWI, ESW2, and VCA23 according to the various switch and volume operations as described above, the CPU 17 turns on the WRITE switch operated by the performer. (335), :: When CP
U 17 c. If the WRITE switch is in the OFF state, the process immediately returns to the above process 331, but if it is in the ON state, the status of the switches PU1 and PU2 read in the above processes 332 to S34 and the setting of the volume 20 The value is stored in the RAM corresponding to the setting number currently set by operating the setting switch.
17 (S36), and repeat the process 33.
Return to 1.

In this way, in SET mode, the switch PUI
, the status of PU2, and the set value of volume 20 are stored in the storage area in RAM 17 provided corresponding to the setting number (“1” to “4”) set by operating the setting switch. is written. Therefore, the performer can set up to four combinations of the type of pickup to be used and the volume adjustment value.

On the other hand, in the above process S31, the current mode is PLA.
If it is determined that the mode is Y, the CPU 17
Based on the external control signal input via the external control signal input circuit 29, it is determined whether the external control signal corresponding to each foot switch output from the foot controller 15 is input via the distributor 14. (S3
7).

Then, when it is determined that an external control signal is input, the CP
The U17 determines the specified setting number based on the input external control signal, and reads the status of the switch PUI, the status of the PU2, and the volume volume 20 from the storage area in the RAM 19 corresponding to the determined setting number. Based on the read information, the electronic switches ESW1 and ESW2 are set on/off, and volume data corresponding to the read setting values is output to the VCA 22 (S39).
), the process returns to step S31.

On the other hand, if the input of the external control signal is not determined in the above process S37, the CPU 17
Determine whether there is a change in the state of the switch (340)
, if the state of the setting switch has been changed, the processes S338 to S39 are performed; if the state has not been changed, the process immediately returns to the process 331.

In this way, the combination of the type of big amplifier to be used and the volume adjustment value can be changed by operating the setting switch or by operating the foot controller 15. In this case, the external control signal input determination processing S37 is the setting switch change determination processing S37.
40, so foot controller 1
The foot operation on foot switch 5 has priority over the setting switch operation.

In this way, in the process 338, the data is stored from the storage area in the RAM 19 corresponding to the setting number set by the foot operation on a predetermined foot switch of the foot controller 15 or the predetermined operation of the setting switch. The current setting information is read out. Therefore, by setting four types of combinations of the type of pickup to be used and the volume adjustment value in advance, the performer can select the desired type of pickup to be used from among the four set combinations. The volume adjustment value can be instantaneously and reliably adjusted by operating the foot switch of the foot controller 15 or by operating the centering switch during the performance without interfering with the performance.

With the above processing, the type of pickup to be used (electronic switch ESWI, ESW
2) and the adjustment value of volume 20 (VCA23)
The effector system 13 is set based on the external control signal outputted from the foot controller 15, and at the same time, the effector system 13 is set based on the external control signal inputted from the foot controller 15 via the distributor 14. Based on the control signal (equal to the external control signal input to the external control signal input circuit 26), the setting number corresponding to the foot-operated foot switch is detected, and then the detected setting number is Determines the combination of chorus, delay, distortion, and reverb effects that should be added to the corresponding musical sound signal, and
An effect corresponding to the specified sending number is added to the musical tone signal outputted from the guitar 11, and the resultant signal is outputted to the guitar amplifier 16. Then, the musical tone signal to which the effect has been added is amplified to a predetermined level by the guitar amplifier 1G, and is emitted to the outside.

In this way, the performer can control the effector simply by operating the foot controller's 150 watt switch.
In the system 13, the type of effect to be added to the musical tone signal, the type of pickup to be used to obtain the musical tone signal, and the adjustment value of the volume of the musical tone signal can be set at the same time.

The above describes an example in which the present invention is applied to an electric guitar, but the present invention is not limited to this. Like an electric guitar, the pickup, volume, etc. Of course, the present invention can also be applied to precent information selection devices for other electronic stringed instruments that require changes in settings.

[Effects of the Invention] As described above in detail, according to the first invention of claim 1, a plurality of combinations of effects to be added to musical sounds and corresponding types of pickups to be used are stored in advance. Since it is now possible to specify the effect to be added to a musical sound and the pickup to be used at the same time by operating the external controller, the performer can perform fingering operations and string operations while playing a song. Even though both hands are occupied, the effect to be added to the musical tone and the big amplifier to be used can be changed instantaneously and easily by foot operation.

Further, according to the second aspect of the present invention, the selection of the type of pickup to be used and the volume setting can be performed instantly and easily by foot operation independently of the designation of the effect.

Further, according to the third aspect of the present invention, in addition to the effect and the pickup to be used, the volume setting can be simultaneously changed instantaneously and easily by foot operation.
