FIG. 3 is a block diagram for explaining an internal configuration of a wearable other multi-effects device in an embodiment of the present invention. FIG. 4 is a flowchart illustrating an effect control method of a wearable other multi- Fig.

The other effector device 300 according to the present embodiment may include a processor 310, a bus 320, a network interface 330, A memory 340, a communication module 350, and a display 360. In other embodiments, the guitar effect device 300 may include more components than the components of FIG. However, there is no need to clearly illustrate most prior art components. For example, the guitar effect device 300 may include other components such as a transceiver.

The memory 340 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. The memory 340 is also provided with a program code for controlling the display of a picture for controlling an effect, receiving an audio signal from a guitar, applying an effect selected in the picture to an audio signal, and outputting the applied audio signal to an amplifier or the like. Can be stored. These software components may be loaded from a computer readable recording medium separate from the memory 240 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 340 via the network interface 330 rather than from a computer readable recording medium.

The bus 320 may enable communication and data transfer between components of the guitar effect device 300. The bus 320 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or other suitable communication technology.

The network interface 330 may be a computer hardware component for coupling the guitar effect device 300 to a computer network. The network interface 330 may connect the guitar effect device 300 to the computer network via a wireless or wired connection.

Communication module 350 may provide functionality for other effector devices 300 to communicate with guitar and audio output devices (i.e., amplifiers) via a wired or wireless network. For example, if the processor 310 of the guitar effect device 300 generates a request (e.g., a selected effect application, etc.) that it has generated in accordance with the program code stored in the recording device, such as the memory 340, And can be delivered to the audio output device via the network.

In this way, control signals, commands, contents, files, and the like provided under the control of the processor 310 of the communication module 350 may be transmitted to the audio output device through the communication module 350 and the network, An audio signal played on the guitar may be received through the communication module 350 of the communication module, the network, and other effect apparatuses of the player.

The display 360 is a touchable panel such as an LCD or an OLED, and can display information and receive information such as a touch of a performer.

The processor 310 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and other input / output operations of the effect device 300. The instructions may be provided by the memory 340 or the network interface 330 and to the processor 310 via the bus 320. The processor 310 may be configured to execute program codes for the screen control section 311, the effect applying section 312 and the signal transmitting section 313. [ Such program code may be stored in a recording device such as memory 240. [

The screen control unit 311, the effect applying unit 312, and the signal transmitting unit 313 may be configured to perform the steps 410 through 490 of FIG.

In step 410, when power is supplied to the guitar effect apparatus 300, the screen control unit 311 may control the main effect screen 300 to display a main screen for effect control. That is, the main screen may be displayed on the display 360. [ The main screen may show the type of effect, display information indicating the volume unit meter of the input sound and output sound, display information for volume control, etc., .

In operation 420, when an operation input for switching to the selection screen is generated on the main screen, the screen control unit 311 can switch the main screen to the selection screen in operation 430. Here, the selection screen may display a screen on which information for selecting an effect is displayed to be applied to a currently input error signal among a plurality of effects.

For example, when any one of the effect information displayed on the main screen is selected (for example, the player selects the effect information by touching the screen or the like), the screen control unit 311 controls the effect Can be switched so that a selection screen for selecting the selection screen is displayed on the display 360. [

If an effect to be applied is selected in the selection screen in step 440, the screen control unit 311 can switch the selection screen to the variable setting screen. At this time, the variables (i.e., parameters) may differ depending on the kind of effect. Accordingly, different variable setting screens may be displayed on the display 360 according to the selected effect.

For example, the screen control unit 311 can confirm the variable information matched with the effect identifier information based on the effect identifier information indicating the type of the effect selected by the player on the selection screen. The screen control unit 311 configures the variable setting screen based on the confirmed variable information, and controls the selected screen to be switched to the configured variable setting screen.

In step 450, the screen control unit 311 can switch the selected screen to a variable setting screen corresponding to the selected effect. When the value of each variable to be applied is selected through the variable setting screen, the effect applying unit 312 can set the variable value of each variable by matching and storing the selected variable value together with the identifier information of the variable. At this time, the set variable values are displayed on the display 360, so that the player can provide the variable values set for the selected effect and the selected effect in real time.

In step 460, the effect applying unit 312 may apply the corresponding effect (that is, the effect selected for applying) to the audio signal input from the guitar based on the set variable value.

For example, when a reverb is to be applied, the effect applying unit 312 can reproduce a reverberation effect by filtering an input audio signal based on a plurality of comb filters.

As another example, when a delay is to be applied, the effect applying unit 312 may store an audio signal corresponding to a predetermined section in the buffer where the input audio signal is buffered, in the memory. Then, the effect applying unit 312 can reproduce the audio signal stored in the memory after a time designated by the user (i.e., a desired time (ms)). At this time, the effect applying unit 312 can reproduce the ringing effect by feedbacking the audio signal by a level designated by the user (i.e., the degree desired by the user).

As another example, when applying Fuzz, the effect applying unit 312 may intentionally amplify an input audio signal and an output audio signal to a predetermined level to reproduce a distortion effect.

As another example, when applying a chorus, a 'modulation' series audio effect is generated using a sine wave modulation using a slight delay corresponding to a predetermined delay level and an LFO (Low Frequency Oscillator) You can reproduce the "chorus" effect.

In operation 470, the signal transmission unit 330 may transmit the audio signal to which the effect is applied to the audio output apparatus (i.e., the amplifier).

At this time, the signal transmitter 330 can transmit the audio signal to the audio output device using the short-range wireless communication module such as Bluetooth. Then, the audio signal to which the effect is applied can be outputted through the audio output device.

If it is determined in step 420 that the operation input for switching to the selection screen has not occurred in the main screen but the operation input for switching to the preset screen has occurred in step 480, As the operation input is generated, the screen control section 311 can confirm that the operation input corresponds to the operation input to the preset screen, based on the received indicator.

In step 490, the screen control unit 311 can switch the main screen to a preset screen. Here, various operations such as switching to a preset screen and setting an effect through a preset screen will be described later with reference to FIG.

5 is an exemplary view of a main screen displayed on a display of a wearable guitar effect device in an embodiment of the present invention.

The main screen 500 may display currently selected effects among a plurality of effects. The user's input signal can be applied serially in order from the audio effect of the left image (in order of 501, 502). Thus, when booting the device for the first time, both can display a bypass image. 5 shows that two effects are displayed on the main screen 500. The user can input the result of applying the Reverb effect 501 and the Fuzz effect 502 to the input signal in order Be provided

 In addition, the main screen 500 includes display information 503 for power control, display information 504 corresponding to the vu meter of the input sound, display information 505 corresponding to the vu meter of the output sound, And may further include a display area 506. By touching the display area 506, the volume can be controlled by one by one or by one by one. Then, when the display information 503 is selected (e.g., touched) by the player on the main screen 500, the program for effect control can be ended. That is, the power supply of the effector device is interrupted and can be terminated.

When an image 501 or 502 corresponding to an effect such as reverberation or fuzz is selected on the main screen 500, that is, when an operation input to a selection screen occurs, the screen control unit 311 controls the main screen 500, Can be switched to the selection screen. For example, if the images 501 and 502 are briefly touched and selected within a predetermined period of time, the main screen 500 can be switched to the selection screen.

When a sliding input is generated while the images 501 and 502 are selected on the main screen 500, the screen control unit 311 can switch the main screen 500 to a preset screen. For example, when a sliding input for pushing the screen in the 360-degree direction such as the up, down, left, right, and diagonal lines occurs with the image 501 corresponding to the reverb effect being pushed, the main screen 500 is switched to the preset screen Can,

FIG. 6 is an exemplary view showing a selection screen displayed on a display of a wearable guitar effect apparatus in an embodiment of the present invention. FIG.

6, when a reverb effect is selected from the main screen 500 and is switched to the selection screen 600, the screen control unit 311 controls the main screen 500 (see FIG. 6) among a plurality of effects displayed on the selection screen 600, The user can activate the image 601 corresponding to the reverb effect selected on the display 360 and display it on the display 360. [

According to FIG. 6, the plurality of effects may include a reverb effect, a fuzz effect, a delay effect, and a chorus effect. The selection screen 600 may include a bypass at the center. Here, the bypass can represent an input signal to which no effect is applied.

In FIG. 6, images 601, 602, 603, and 604 of each effect may indicate display information for controlling an effect corresponding to the image when the corresponding image is selected through a touch or the like. For example, although not physically implemented as a button, an indicator for operating as a button and each image may be matched and stored in advance. Then, when each image is selected, identifier information indicating the type of the indicator and the effect can be transmitted to the screen control unit 311 on the display 360. The screen control unit 311 can display any effect Is selected, and can switch the current screen to the corresponding screen based on the confirmation.

At this time, if the display information 605 corresponding to bypass is selected, the screen control unit 311 can initialize the selection of the previously selected effect and switch the selection screen 600 back to the main screen 500 .

For example, when the reverb effect is selected and switched to the selection screen 600 on the main screen 500, the reverb effect is activated and displayed on the selection screen 600. However, when the bypass is selected, Can be deselected by displaying the activated reverb effect by deactivating it. Then, the screen control unit 311 can return the selection screen 600 to the main screen 500 again.

FIG. 7 is an exemplary diagram illustrating a variable setting screen for setting a variable corresponding to a specific effect selected in an embodiment of the present invention. FIG.

7 is an exemplary diagram illustrating a screen for setting variables corresponding to reverberation among a plurality of effects.

7, when the reverberation effect 601 is touched and selected on the selection screen 600, the screen control unit 311 displays the corresponding variable information (room size) based on the identifier information of the reverberation effect and the selection indicator, (Damping), wet (wet), and dry (dry), the variable setting screen 700 can be configured. The screen control unit 311 can switch the selection screen 600 of the display 360 to the variable setting screen 700.

At this time, the interface of the variable setting screen is the same for each effect, but the name of the variable may be different according to the kind of effect.

For example, all variables can be unified into multiple levels of values from 0 to 1.

For example, in the case of a reverb, there are roomsize (room size) for setting the size of a room to be simulated, damp (damping) for setting the hardness of the surface of a room to be simulated, Dry (dry) for setting the volume, and Wet (?) For setting the volume of the signal after the sound effect can be used.

As another example, in the case of delay, you can set Left (Left) to set the delay time (ms) of the left channel audio, Right (Right) to set the delay time of the right channel audio, A feedback variable may be used.

As another example, in the case of fuzz, there are Fuzz (fuzz) for setting the degree of distortion of the input signal, and Wet / Dry (? / Dry) for setting the ratio of the distorted signal to the input signal without the effect Can be used. For example, in the Wet / Dry (? / Dry) variable, when 0 is a value of 1, 0 is output only the input signal without the effect, 1 is output only the distorted signal, 0.5 is the signal You can display the output half way through the signal.

As another example, in the case of a chorus, an LFO (ELFO) for setting the frequency of a sine wave to be used for sine wave modulation, a Depth for setting the level at which the sine wave modulation affects the signal, A feedback variable can be used to set the degree of delay effect.

Referring to FIG. 7, the x-axis coordinate and the y-axis coordinate of each of the two-dimensional planes of the variable setting screen 700 can indicate the variable value of the corresponding effect. The O-shaped labels 701 and 702 displayed on the variable setting screen 700 may indicate display information used for adjusting variable values of the effect. For example, when the player sets the room 702 in relation to the reverb effect by adjusting the movement of the label 701 in the direction of the upper, lower, left, right, diagonal, etc. (for example, by dragging and dropping to a desired point) And variable values for damping can be finely adjusted. Then, when the application indication information 703 is selected to apply the adjusted variable value, the effect application unit 312 can set the variable value of the variable of the effect to the adjusted variable value. At this time, when the cancel display information 704 is selected, the effect applying unit 312 can cancel the variable value setting. At this time, if the cancel display information is selected, the user can return to the selection screen 600 again.

Thus, as the type of the effect selected by the player and the variable value set in association with the effect are displayed on the display 360, the player can stably play while confirming the adjusted effect and variable value in real time.

8 is a diagram illustrating an example of a preset screen displayed on a display of a wearable guitar effect apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 8, the preset screen 800 can be used for presetting the types of effects frequently used by the performer and the set values of the variable values of the effect. In addition, the preset screen 800 may display a screen that provides a sample that includes preset effects of variable values to aid novice players in the guitar effects device 300. For example, a pre-set sample of commonly used effects and variable values may be provided on the preset screen 800, and the sample may be deleted or modified. That is, the variable value of the sample can be modified.

In FIG. 8, a case where five presets are set and stored and held will be described as an example. However, five presets and less than five presets may be set.

Referring to FIG. 8, preset 1 801 and preset 2 802 are preset by bypass / bypass, preset 3 803 is preset by reverb / delay, preset 4 804 ) Indicates a case where the reverb / fuzz is preset, and the preset 5 (805) indicates a case where the fuzz / chorus is set in advance.

In the case of Bypass, such as Preset 1 (801) and Preset 2 (802), there is no specified effect, so you can specify the desired effect. For example, the left bypass of the preset 1 801 can be set to reverb, and the right bypass can be set to fuzzy. At this time, the variable value of each effect can also be set, and the variable value set in the preset 1 (801) and the corresponding effect (reverberation / chorus) can be matched and stored. For example, the identifier information of the preset 1 (801), the identifier information of the specified effect, and the variable value may be stored and maintained in a matching manner with each other. Then, when the display information of the preset 1 (801) is selected on the screen, the effect applying unit 312 adds the identifier information of the effect matched based on the indicator indicated by the indication information of the preset 1 (801) The effect can be applied to the input audio signal.

The preset screen 800 includes not only the five presets 801, 802, 803, 804 and 805 but also display information 806 and 807 corresponding to up and down buttons, Information 808 and display information 809 corresponding to a record button.

For example, when the preset screen 800 is displayed on the display 360, the player can select desired presets by operating the display information 806 and 807 corresponding to the up or down buttons. Then, by selecting the display information 808, the selected preset can be immediately applied to the audio signal. For example, an effect to be applied can be directly selected and applied as a simple operation of selecting a preset through a desired preset screen 800 during performance.

Here, the display information 808 may be display information indicating a preset selection button, and the display information 809 may be display information indicating a preset storage button. At this time, if the desired effect combination is set by the player (i.e., the user) and the display information 809 is selected in the preset screen 800, it can be stored in the form of [preset numbering] [left effect / right effect name] have.

Since the input audio signal is applied in the order of the left effect and the right effect as shown in FIG. 5, even though the effect setting values of [Reverb / Delay] and [Delay / Reverb] are the same, Can exist.

If the display information 808 is selected, the preset is set, but the screen may remain on the preset screen 800, that is, the page corresponding to the preset screen.

If display information 809 is selected, a new preset can be set at the bottom of the preset list, and it can remain in the preset page as it is.

Referring back to the preset screen 800 of FIG. 8, if the player wishes to set a preset with a new effect he or she wants, or to change the effect of an existing preset that has already been stored, the up / down display information 806, When the display information 809 corresponding to the selected preset is selected, after the effect and variable values of the selected preset are set, if the display information 809 is selected, the current setting may be set as a preset and stored and maintained. The screen control unit 311 can switch the preset screen 800 to the main screen 500 by sliding the screen with the finger on the screen in the preset screen 800. [
