Referring to fig. 1, an embodiment of the present invention provides a method for controlling a stringless guitar, including steps S1 to S4, specifically:
s1, identifying a key combination instruction of a user based on a preset tone instruction and a preset rhythm instruction.
A set of preset pitch commands and tempo commands needs to be defined. These instructions and functions can be designed according to the requirements and functions of music, such as the note level, duration and intensity, and the speed, beat and decomposition effect of rhythm. Each instruction should be associated with a corresponding tone color library in order to select the correct tone color after instruction identification. And designing corresponding key combinations according to preset tone and rhythm instructions. Different instructions may be mapped to specific keys or key combinations. The key combination may be triggered by pressing multiple keys simultaneously or by pressing a particular sequence of keys. The user inputs a key combination command to the system by pressing a keyboard, knob, or other feature on the stringless guitar that is used to generate the command. The key information is transmitted to an instruction recognition system for recognition processing. It will be appreciated that the stringless guitar of the present application does not have physical strings to detect string vibrations to sound in order to avoid physical injury to the finger from long term string pressing and plucking. The key combination instruction refers to the triggering of the instruction by means of identifying the key action of the stringless guitar, the poking of the poking plate poking rod, and identifying the modes of touch, air chord sweeping, infrared chord sweeping, pressure sensing, gesture identification and the like.
S2, generating MIDI protocol data according to the key combination instruction;
and mapping the preset tone command to the corresponding notes according to the key combination pressed by the user. For example, key a corresponds to bass C, key B corresponds to treble D, and so on. And judging whether control signals such as tone switching, volume adjustment and the like which need to be sent exist according to the key combination instruction of the user. According to specific requirements, corresponding control signals are selected. Based on the notes and the control signals, corresponding MIDI events are constructed. Common MIDI events include Note On, note Off, control Change, etc. The generated MIDI events are ordered and combined according to the time axis according to the order and duration of the user keys. The correct playing sequence of notes and accurate duration are ensured. The generated MIDI event is packed into a complete MIDI message, wherein the MIDI message is composed of a MIDI header and a MIDI data block, wherein the MIDI header contains information such as sync byte and status byte, and the MIDI data block contains actual MIDI event data. Therefore, the step can convert the key combination instruction of the user into corresponding MIDI protocol data.
S3, generating an analog signal based on the MIDI protocol data and pre-stored digital music data;
and analyzing the MIDI protocol data in each received MIDI message. According to the format and the instruction specified by the MIDI protocol, analyzing the information of notes, volume, tone and the like, and according to the analyzed tone information, selecting the matched tone from the pre-stored digital music data. Wherein different instruments have different timbres, and the sound characteristics of various instruments can be simulated by adjusting timbre parameters. And processing corresponding parameters of the audio according to specific requirements for control signals obtained through analysis, such as volume adjustment, tone switching and the like. The influence of the control signal is achieved, for example, by changing the volume gain, the filtering effect, the reverberation effect, etc. And synthesizing the selected tone color and the processed audio data. The waveforms of different notes are superimposed together by synthesis techniques to generate a composite audio signal with characteristics of pitch, volume, etc., and then the synthesized digital signal is converted to an analog signal.
S4, transmitting the analog signals and the MIDI protocol data to a playing device.
For MIDI protocol data, a standard MIDI interface or USB-MIDI interface is typically used for transmission. For analog signals, it is often necessary to transmit them to a playback device using an audio interface or cable. The audio interface may be a dedicated audio interface device or may be a built-in sound card or an external sound card of the computer. By connecting the appropriate audio cable, the analog signal is output to the input port of the audio interface.
As described above, a method of generating music based on an algorithm is employed. By generating music using an algorithm instead of pre-storing a large number of pieces of music, the required storage space can be greatly reduced. The music generated by the algorithm can generate corresponding musical elements such as notes, chords, rhythms and the like in real time according to the input instruction and the set parameters of the user. Second, using a technique of synthesizing tone colors and sound effects, sound simulation of various musical instruments can be achieved through digital signal processing. Therefore, only a small amount of tone color and sound effect data are stored, and the sound effect can be dynamically called and generated in real time in the playing process, so that the occupation of the storage space is greatly reduced. Meanwhile, through converting the key combination instruction of the user into MIDI protocol data and combining with preset digital music data, rich and various musical compositions can be generated. The user can create different notes, timbres and control signals by pressing keys, thereby playing music with personal style and creativity. The playing process of the guitar without strings has high flexibility and creativity, and a user can freely combine different notes and timbres according to own preference and creative, so as to create unique musical compositions.

And performing post-processing such as editing, denoising, balancing and the like on the recorded audio to obtain better tone quality effect, and then saving the processed audio as a WAV format file for subsequent processing and storage. And sampling the audio data in the WAV file by using parameters such as sampling rate, bit depth and the like to obtain discrete audio samples. The sampled audio samples are converted to digital tone data, typically represented using PCM (pulse code modulation) format or other compression coding format. And processing the digital tone data, such as data compression, coding optimization and the like, so as to reduce the occupation of storage space. The processed digital tone color data is then stored in a memory. According to the embodiment, different tone colors of different musical instruments and corresponding playing methods can be recorded and converted into digital tone color data, and necessary materials and resources are provided for subsequent music generation and control.

In this embodiment, the user key combination instruction is converted into a corresponding MIDI event, for example, a Note On/Off event, a Control Change event, etc., by parsing the user key combination instruction. According to the MIDI protocol specification, the attribute and parameters of each event, such as event type, channel, note number, dynamics, rhythm, etc., are determined. All MIDI events are arranged and organized in a specified order according to the format and requirements of the MIDI protocol to form a continuous sequence of MIDI events. Each MIDI event is converted to a corresponding byte code for subsequent transmission and storage in accordance with the specifications and standards of the MIDI protocol. The format and parameters of each byte code, such as event type, channel, data value, etc., are determined according to the MIDI protocol specification. All MIDI events are encoded and combined into a complete byte stream data, namely the generated MIDI protocol data. Through the embodiment, the key combination instruction of the user can be converted into the corresponding MIDI event, and MIDI protocol data is generated according to the MIDI event, so that the music generation and control function based on the preset tone instruction and the rhythm instruction is realized.
