Short Content: 1 introduction     Based on the RTX51 music edition generator take at89S52 monolithic integrated circuit as the control core, the operator may through 4×4 the matrix keyboard input agreement form random music, after "broadcast" key, the system then starts the music which broadcasts edits, and the tonality and the metre may by the monolithic integrated circuit accuracy control. In order to reduce the cost, in the smallest hardware design's foundation, system's function uses the software to realize as far as ...
