Abstract
The present invention relates to a pedal movement control and recording apparatus for an automatic music playing piano in which the pedal displacement corresponding to sequentially changing pedal control signals is determined in order to generate a pedal position conversion table, and which provides means for generating position data normalization tables and reverse normalization tables, whereby music performed on one piano can be replayed on a second automatic music playing piano, correcting for the unique response characteristics of each piano, thereby preserving nuances of pedal movement during replay.
