The fingerboard module 5 and the strings 2 can determine the target note or target chord tone.
[0047] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on guitar 1 and may include more or fewer parts than shown, or combine certain parts, or have different arrangements of parts.
[0048] Reference Figure 2 , Figure 2 This is a schematic diagram of the hardware operating environment involved in the guitar solution of this invention. (See diagram below.) Figure 2 As shown, the guitar 1 may include: a guitar control device 6, strings 2, and a pressing device 3, wherein the strings 2 and the pressing device 3 are both connected to the guitar control device.
[0049] The guitar control device 6 may include: a processor 601, such as a central processing unit (CPU) or a chip capable of digital signal processing (DSP), a communication bus 602, and a memory 603. The communication bus 602 is used to enable communication between these components. The memory 603 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. Optionally, the memory 603 may also be a storage device independent of the aforementioned processor 601.
[0050] like Figure 2 As shown, the memory 603, which serves as a storage medium, may include an operating system, a data storage module, a sound synthesis module, a signal processing module, and a guitar control program.
[0051] exist Figure 2 In the guitar control device shown, the processor 601 and memory 602 of the guitar control device of the present invention can be set in the guitar control device. The guitar control device calls the guitar sound control program stored in the memory 603 through the processor 1001 and executes the guitar sound control method provided in the embodiment of the present invention.
[0052] This invention provides a guitar sound control method, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of a guitar sound control method according to the present invention.
[0053] In this embodiment, the guitar sound control method includes:
[0054] Step S10: Obtain the first pressing state parameter of the pressing device and the triggering parameter of the triggering signal of the string;
[0055] The first pressure state parameter here refers to the parameters generated by the pressing device, including parameters such as the pressing state, the pressing pressure, and the non-pressing state. The trigger signal here is generated by detecting the signal of the string being plucked. Specifically, plucking a string generates a trigger signal, and the waveform of this trigger signal is not limited to triangle waves, square waves, etc. The trigger parameters here include the presence or absence of a trigger signal, and can also be the voltage of the trigger signal.
[0056] Step S20: Determine the target playing technique for the target note or target chord tone based on the first pressing state parameter and the trigger parameter;
[0057] The target playing techniques here can be muting, damping, and harmonics. In acoustic guitar, one technique for muting is to press the thenar eminence of the right hand against the end of the string near the bridge, preventing the string from vibrating fully; playing the string at this time produces a muted effect. Damping has left-hand and right-hand techniques. In acoustic guitar, for right-hand damping, after strumming the string with the right hand, quickly press the thenar eminence of the right hand against the string to stop the vibration. For harmonics, in acoustic guitar, first lightly touch the string with your finger, then lift your finger the instant you pluck the string to produce a harmonic. Since it's difficult to detect string touch in digital guitars, the target playing techniques are made possible by placing the pressing device adjacent to the string plucking area.
[0058] Step S30: Determine the playback control parameters of the target note or target chord tone based on the target playing technique;
[0059] The playback control parameters here are used to control the playback of the target note or chord tone. Specifically, they can control the timbre of the target note or chord tone, and stop playback when the target note or chord tone is played, achieving a muting effect. Different target playing techniques correspond to different playback control parameters.
[0060] Step S40: Control the playback of the target note or target chord tone according to the playback control parameters.
[0061] The playback of the target note or target chord tone is controlled according to the playback control parameters. During playback, the playback control parameters can be changed, and the playback of the target note or target chord tone changes according to the change of the playback control parameters.
[0062] In this embodiment, compared to current digital guitars, the pressing device is arranged adjacent to the plucking area of the strings, which facilitates switching playing techniques by pressing the pressing device and plucking the strings during performance. The target playing technique is determined by the first pressing state parameter and the triggering parameter of the string trigger signal. Since the playback control parameters are determined according to the playing technique, the playback control parameters can be changed, so that the timbre of the played chords and the pauses in the playback process change according to the change of playing technique, thereby increasing the flexibility of the digital guitar in playing chords.
[0063] Furthermore, based on the first embodiment, a second embodiment of the guitar sound control of the present invention is proposed. In this embodiment, reference is made to... Figure 4 The first pressing state parameter and the triggering parameter are parameters detected within a first preset time period. The step of determining the target playing technique of the target note or target chord tone based on the first pressing state parameter and the triggering parameter includes:
[0064] Step S21: When the first pressing state parameter remains in the pressing state and the trigger parameter indicates the presence of the trigger signal, the target playing technique is determined to be muted.
[0065] The first preset duration can be fixed or user-defined, specifically 15 milliseconds. The pressing state refers to the pressing device being pressed for a duration exceeding a pressing threshold. Specifically, the pressing threshold duration can be set to 3 milliseconds; that is, a pressing state is defined as the pressing device's pressing duration exceeding 3 milliseconds. This pressing threshold duration can be fixed to prevent accidental touches by the user during performance. Within the first preset duration, the first pressing state parameter is in a pressing state at every moment, and the trigger parameter determines the target playing technique as a muted note when the trigger signal is present.
[0066] Step S22: When the first pressing state parameter is a change from pressing state to non-pressing state, and the triggering parameter is the presence of the triggering signal in the pressing state, the target playing technique is determined to be overtone;
[0067] Here, the pressed state changes to the non-pressed state, corresponding to the pressing device changing from being pressed to not being pressed. The trigger parameter here exists in the pressed state, indicating the presence of the trigger signal.
[0068] Step S23: When the triggering parameter is that the triggering signal exists, and the first pressing state parameter is that the first pressing state parameter changes from the non-pressing state to the pressing state after the triggering signal, the target playing technique is determined to be muting.
[0069] Here, the transition from the non-pressed state to the pressed state corresponds to the pressing device changing from an unpressed state to a pressed state. In other embodiments, different target playing techniques are determined based on the number of changes in the first pressing state parameter and the trigger parameter. Specifically, when the number of changes in the first pressing state parameter is 1, the target playing technique is determined to be a muted tone; when the number of changes in the first pressing state parameter is 2, the target playing technique is determined to be an overtone; and when the number of changes in the first pressing state parameter is 3, the target playing technique is determined to be a muted tone.
[0070] In this embodiment, within a first preset duration, different playing techniques are determined based on the first pressing state parameter and trigger parameter. Since different playing techniques have different timbres, the flexibility of playing chords on the digital guitar is increased.
[0071] Furthermore, based on the second embodiment, a third embodiment of the guitar sound control of the present invention is proposed. In this embodiment, the step of determining the playback control parameters of the target note or target chord tone according to the target playing technique includes:
[0072] When the target playing technique is muted tone, the playback control parameter is determined to play the target note or target chord tone with a muted tone.
[0073] When the target playing technique is overtone, the playback control parameter is determined to play the target note or target chord tone with overtone timbre.
[0074] When the target playing technique is muting, the playback control parameter is to stop playing the target note or target chord.
[0075] The playback control parameters here are used to control the guitar to play the target note or target chord tone. The muted tone here corresponds to the muted tone of an acoustic guitar. The overtone tone here corresponds to the overtone tone of an acoustic guitar. Stopping playback of the target note or target chord tone here means stopping playback of the target note or target chord tone.
[0076] In this embodiment, different playback control parameters are determined according to different target playing techniques, so that there are corresponding playback control parameters for the target playing techniques. Since the playback control parameters control the playback of the target notes or target chord tones, there can be a variety of different playback methods, increasing the flexibility of the digital guitar's chord playback.
[0077] Furthermore, based on the second embodiment, a fourth embodiment of the guitar sound control of the present invention is proposed. In this embodiment, before the step of determining the target playing technique of the target note or target chord tone according to the first pressing state parameter and the trigger parameter, the method further includes:
[0078] When the first pressing state parameter of the pressing device changes from a non-pressing state to a pressing state, or when the string has the trigger signal, the current time is determined to be the initial time of the first preset duration, and the step of obtaining the first pressing state parameter of the pressing device and the trigger parameter of the trigger signal of the string is executed.
[0079] In this embodiment, the initial time of the first preset duration is determined by the change in the first pressing state parameter, or by the trigger signal. The first preset duration can be determined based on the initial time and the duration.
[0080] In this embodiment, when the first pressing state parameter of the pressing device changes from a non-pressing state to a pressing state, or when the string has the trigger signal, the current time is determined to be the initial time of the first preset duration, and the range of the first preset duration can be determined. Since the target playing technique is determined within the first preset duration, the accuracy of the guitar in determining the target playing technique is improved.
[0081] Based on any one of the first and third embodiments described above, a fifth embodiment of the guitar sound control of the present invention is proposed. In this embodiment, reference is made to... Figure 5 The step of determining the target playing technique for the target note or target chord tone based on the first pressing state parameter and the trigger parameter includes:
[0082] Step S201: When the first pressing state parameter is a pressing state, and the trigger parameter is that the trigger signal exists in the pressing state, the target playing technique is determined to be muted.
[0083] In this embodiment, the presence of the trigger signal is required during the pressing state.
[0084] After the step of controlling the playback of the target note or target chord tone according to the playback control parameters, the method further includes:
[0085] Step S501: During the process of playing the target note or target chord tone according to the playback control parameters corresponding to the muted tone, the second pressing state parameter of the pressing device is detected.
[0086] Specifically, the second pressing state parameter of the pressing device is detected while the target note or target chord tone is played.
[0087] Step S502: When the second pressing state parameter changes from the pressing state to the non-pressing state, the target note or target chord tone is played according to the playback control parameter corresponding to the overtone.
[0088] The target note or target chord tone here is the same as the target note or target chord tone in step S501. Specifically, it is necessary to determine the part of the target note or target chord tone to be played according to the playback control parameters corresponding to the muted tone, and then play the unplayed part of the target note or target chord tone according to the playback control parameters corresponding to the overtone.
[0089] Step S503: When the second pressing state parameter is to maintain the pressing state, the target note or target chord tone is played with the playback control parameter corresponding to the muted tone.
[0090] In this embodiment, when the second pressing state parameter is to maintain the pressing state, since the target playing technique is still a muted tone, the target note or target chord tone is played with the playback control parameter corresponding to the muted tone.
[0091] In this embodiment, before determining whether the target playing technique is a muted tone or a harmonic, the target note or target chord tone is played according to the playback control parameters corresponding to the muted tone. This ensures the timeliness of chord playback, reduces the time difference between the plucking moment and the chord playback moment, and lowers the delay in guitar chord playback.
[0092] Furthermore, based on any of the above embodiments, a sixth embodiment of the guitar sound control of the present invention is proposed. In this embodiment, the target note or target chord tone includes preset samples of different timbres, and the step of controlling the playback of the target note or target chord tone according to the playback control parameters includes:
[0093] The preset sample corresponding to the playback control parameter in the target note or target chord tone is determined as the target sample;
[0094] The playback of the target sample is controlled according to the playback control parameters.
[0095] For the same chord, the timbre will differ due to different playing techniques. Therefore, this application pre-records samples of target notes or target chord tones played using different playing techniques; these are called preset samples, and the timbre differs between the preset samples. The corresponding preset sample is determined according to the playback control parameters.
[0096] In this embodiment, the target note or target chord tone includes multiple preset samples, and the preset samples can be determined as target samples for playback according to the playback control parameters, so that the guitar can play chords with different timbres, thereby increasing the variety of chords that the guitar can play.
[0097] Further, the step of determining the preset sample corresponding to the playback control parameter in the target note or target chord tone as the target sample includes:
[0098] When the playback control parameter is to play the target note or target chord tone with a muted tone, the preset sample of the muted tone in the target note or target chord tone is determined as the target sample;
[0099] When the playback control parameter is set to play the target note or target chord tone with overtone timbre, the preset sample of the overtone timbre in the target note or target chord tone is determined as the target sample.
[0100] In other embodiments, the preset sampled timbre may also be a plucked tone, a vibrato, a trill, etc.
[0101] In this embodiment, different preset samples are determined by different playback control parameters, which makes the playback methods of target notes or target chord tones diverse, thereby increasing the flexibility of digital guitar playback chords.
[0102] Furthermore, based on any of the above embodiments, a seventh embodiment of the guitar sound control of the present invention is proposed. In this embodiment, the step of controlling the playback of the target note or target chord tone according to the playback control parameters includes:
[0103] The guitar's playback volume is reduced according to the volume adjustment rate;
[0104] When the playback volume is less than or equal to a preset threshold, the playback of the target note or target chord tone is stopped.
[0105] In acoustic guitar, muting refers to reducing string vibration, thus achieving muting. That is, muting is not an instantaneous pause in playback. The volume adjustment rate here is determined based on one or more of the current guitar volume, tone, first press state parameter, and trigger parameter. In this embodiment, specifically, the pressing device can detect the pressing pressure and determine the volume adjustment rate based on the pressing pressure of the first press state parameter; the volume adjustment rate is positively correlated with the pressing pressure. In other embodiments, the volume adjustment rate is positively correlated with the guitar volume.
[0106] Specifically, the preset threshold here can be zero. When the playback volume is lower than the preset threshold, the playback of the target note or target chord tone stops.
[0107] In this embodiment, the volume of the preset sample is reduced by the volume adjustment rate, and when the volume equals a preset threshold, the playback of the preset sample is stopped, which improves the similarity between the guitar and the acoustic guitar when the guitar is cut off.
[0108] Furthermore, this invention also proposes a storage medium storing a guitar sound control program, which, when executed by a processor, implements the steps of any of the guitar sound control method embodiments described above.
[0109] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system.

[0111] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods of the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
