AN AUTOMATIC PERFORMANCE PIANO OF FREELY SETTING A MUSICAL PROGRAM AND METHOD FOR AUTOMATIC PERFORMANCE

摘要

It is a method to convert you to want the data processing of the present invention of the music played, to be saved on microcontroller and electrical signals, system is converted the electrical signal to by transmitting from a data-signal of microcomputer piano, because solenoid is activated by an electric signal, it is played to the automatic player piano musical instruments on automatic player piano, a kind of free method of automatic player piano is ready. ;The present invention be coupled to the connecting rod vertical direction that drives in by a solenoid operate on the bottom end of keyboard, it is applied to played solenoid music data, it is converted into the electric signal from the signal converter on the motherboard connecting with operating switch, including data screen stores music file to PC; Transmit the data in the PC being stored on motherboard; Conversion data is transmitted from PC by signal converter into an electric signal; The step electric signal converted is applied to operating switch; The driven step of solenoid; Key step is automatically by a solenoid-activated; Depending on when hammer hit, stringed musical instrument is made of a step, and user has no relations active wants to listen can play the piano oneself the music of a when and where to play the piano for you.
