ABSTRACT:
A device and method prevents the imbalance of emission timing between strong key strokes and weak key strokes in an automatic performing piano by preventing the occurrence of reverse phenomenon and overlap phenomenon by correcting cessation timing according the order or sequence of key strokes. A reverse phenomenon, where cessation timing for one key stroke precedes its counterpart emission timing, is prevented by changing cessation timing to occur after emission timing. An overlap phenomenon, where emission timing for the latter of two successive strokes precedes cessation timing for the former stroke, is prevented by changing the cessation timing to occur prior to the emission timing. The method and device thus achieves reproduction of performance with balanced and controlled sound emission timing and high fidelity in performance reproduction.
