Abstract: A method for generating a music file for recording user performance may include: detecting, by a sensor, an event indicating a status change of an execution device of the keyboard instrument; generating, by the sensor, a signal corresponding to the detected event; receiving, by a processor, the signal; and generating, by the processor, a music file based on the signal. In some embodiments, the execution device may include a weight lever. The weight lever may a concrete structure in the keyboard instrument to simulate a rebound force generated by hammer striking on string, by striking on an elastic structure. In some embodiments, a rebound force for a first weight lever may be different from a rebound force for a second weight lever by adjusting parameters of the elastic structure or the weight lever.

Abstract: Systems and methods for providing a piano system are provided. In some embodiments, the methods include receiving a plurality of key signals related to a first performance of a piece of music, wherein each of the plurality of key signals corresponds to motion of at least one key of a piano during the first performance; generating first performance information based on the plurality of key signals; receiving musical data related to a second performance of the piece of music; receiving musical data related to a second performance of the piece of music, generating second performance information based on the musical data; and providing content for presentation on a display device based on the first performance information and the second performance information. The methods can also include receiving at least one pedal signal corresponding to motion of a pedal of the piano during the first performance, and generating first performance information based on the pedal signal.

Abstract: A heat dissipation system for a smart piano may include a heat dissipation driver, a heat dissipation device, a sensor, a protection circuit and a hardware processor. The sensor may be configured to detect a thermal parameter of an execution device of the smart piano. The protection circuit may be configured to analyze the thermal parameter to generate a protection signal. The hardware processor may be configured to determine a preset algorithm, generate a control signal according to the protection signal and the preset algorithm, and control a heat dissipation condition of the smart piano. The controlling the heat dissipation condition of the smart piano may include control an operation condition of the execution device and/or the heat dissipation device. The controlling may include controlling an output power of the execution device and/or the heat dissipation device.
