摘要：
An automatic player piano records an original key motion reciprocated between a rest position and an end position as a series of a key-on event, a hammer event and a key-off event by using key/hammer sensors, and supplements the key/hammer event for an unusual key motion such as a half stroke, thereby faithfully reproducing the original key motions in a playback mode.
