[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0015] This system uses modular design to achieve efficient management of electronic piano music resources in the cloud. The modules work together as follows: As the core hub, the central control and dispatching module adopts a low-latency communication protocol to coordinate data interaction between the cloud server cluster, user terminal module and electronic piano device in real time, ensuring the efficient transmission of music scores, audio and control commands.

[0016] After receiving a track selection command from the user terminal, the dynamic score generation module accesses the cloud-based score database to generate a dynamic score with highlighted indications of the original vocal track. The dual chord rendering engine uses layer overlay technology to highlight both letter chords and progressive chord fingerings on the score interface. The embellishment score generator automatically analyzes and annotates embellishments based on the musical style, and the high-definition PDF export unit converts the generated score into a printable format.

[0017] The vocal score engine synchronizes with the notes played on the keyboard in real time, adjusting the speed and pitch of the score using a variable speed and pitch processor to generate an adaptive audio stream. The original sound removal unit uses voiceprint recognition technology to separate the human voice from the accompaniment, ensuring the purity of the singing audio.

[0018] The high-definition accompaniment library stores multi-track separate accompaniment files, the multi-mode noise reduction processing module can independently eliminate the main melody, chords or percussion tracks, and the in-vehicle adaptation module automatically converts the file format to adapt to different in-vehicle systems.

[0019] The user terminal module's interactive interface integrates features such as a music sheet display area and an intelligent collection management unit. This unit supports user-defined directory structures, generates personal music sheet books, and synchronizes these across terminals to the associated electronic keyboard device in real time via a cloud-based synchronization engine. A third-party service gateway provides a standardized interface for data interoperability with the in-vehicle entertainment system.

[0020] The following describes the implementation of the system in conjunction with specific components: The central control and dispatching module is deployed on the core node of the cloud server cluster, adopts a distributed architecture design, and realizes low-latency communication with the user terminal module and the electronic piano device through the MQTT protocol. The data transmission delay is controlled within 50ms.

[0021] The dynamic score generation module runs on a cloud-based application server. When a user selects a track through the user terminal module's interactive interface, a dual chord rendering engine displays letter chords on the left side of the score display and progression chords on the right side, highlighting the currently playing chord using different colors. The embellished score generator automatically adds vibrato annotations for classical music and portamento cues for popular music. Generated scores can be exported and printed using a high-definition PDF export unit.

[0022] The vocal singing engine is integrated into the user terminal module. When the user adjusts the parameters through the variable speed and pitch controller, the variable speed and pitch processor synchronously adjusts the singing speed (range: 60-180BPM) and pitch (±6 semitones). The original sound elimination unit processes the accompaniment file, separates and eliminates the vocal track.

[0023] The high-definition accompaniment library, stored in a cloud storage cluster, contains over 10,000 multi-track accompaniments. Users can choose to remove the main melody, chords, or percussion tracks through the interactive interface. When connected to the in-vehicle system, the in-vehicle adapter module automatically converts the accompaniment to MP3 or WAV format.

[0024] The intelligent collection management unit allows users to create custom directories and generate personal music score books within the interactive interface. These are then synchronized to the bound electronic keyboard device in real time via the cloud-based synchronization engine, with a synchronization delay of no more than 3 seconds. The score request registration unit records user requests and, when the demand for a particular piece exceeds a threshold (e.g., 100 times per week), triggers a background score update process.

[0025] The present invention and its implementation methods are described above. This description is not restrictive. In short, if ordinary technicians in this field are inspired by it and do not depart from the purpose of the invention, they can creatively design structures and embodiments similar to the technical solution, which should fall within the scope of protection of the present invention.
