Wang Xiaowei's piano is not specially made. Wang Xiaowei's piano is a double-row key, which originated from the organ; It is named because it is played in a similar way to an organ. The appearance of the famous instrumental singing group "September Miracle" brought the double-row keys into public view. There are nearly a thousand timbres, and the sound quality is close to that of real musical instruments. Moreover, the timbre can be edited according to the needs of music, such as the strength of the head, such as the speed and amplitude of kneading strings. Each row of keyboards can be superimposed with several different timbres, which can play the effect of a powerful band.
