ABSTRACT:
An automatic player piano has a released key velocity estimator for modifying the constant released key velocity of a piece of music data information to a target released key velocity; a memory stores relation between the target key velocity estimator and other key-touch factors such as a final hammer velocity and a time interval between an impact timing and a key release timing, the released key velocity estimator supplies the key-touch factors to the memory so as to read out the target key velocity estimator, and modifies the piece of music data information so as to indicate the target released key velocity.
