摘要
An ideal automatic player piano is assumed to reproduce an original performance from fundamental data representative of a fundamental forward key trajectory and a backward key trajectory; however, if an actual automatic player piano reproduces a forward key trajectory and a backward key trajectory on the basis of the fundamental data, the forward key trajectory and the backward key trajectory do not faithfully reproduce the original key motions; for this reason, the actual automatic player piano learns first offset time at the end position and second offset time at an intermediate position between the end position and the rest position so as to determine a virtual forward key trajectory and a virtual backward key trajectory, and further learns first dead time around the rest position and second dead time around the rest position so as to exactly determining first starting time at the rest position and a second starting time at the end position, thereby moving keys along composite forward/backward trajectories for imparting a final hammer velocity to a hammer associated with the key to be moved in playback.
