摘要：
An automatic player piano has key sensors for producing digital key position signals representative of current key positions and a recording unit for producing pieces of music data information on the basis of the key motions; however, the key sensors have individualities, and vary the values of the digital key position signals in different ranges, respectively; the recording unit selects different components bits from each of the digital key position signal depending upon the value at a reference point so as to make the difference between the ranges small.
