Abstract: A keyboard musical instrument includes a string-striking mechanism (hammer), driver, sound receiver, analyzer, and adjuster. The hammer strikes a string responsive to a change in position of an associated key of keyboard. The driver drives the hammer under a driving condition in accordance with control data. The sound receiver generates an audio signal corresponding to a sound occurring in the vicinity of the hammer. The analyzer detects the hammer striking a string by analyzing the audio signal generated when the hammer operates. The adjuster adjusts the control data in accordance with results of the analysis. The analyzer detects hammer striking a string in accordance with an intensity of the audio signal occurring within a search range, which has a predetermined relationship along a time axis with regard to a time at which the hammer commences operation.

Abstract: In a musical instrument, such as a piano, having a sound board, the sound board vibrates in response to vibrations of a string responsive to depression of a key. A waveform corresponding to such vibrations of the sound board is detected and recorded. The recorded vibration waveform is usable for reproduction of a sound based on sound board vibrations. In a sound reproduction apparatus, such as a piano, having a sound board, an excitation device physically excitable in response to an input waveform is provided on the sound board. A signal indicative of a vibration waveform of the sound board is received, and the excitation device is driven in accordance with the received waveform signal so that the sound board is vibrated. Thus, a sound based on the sound board vibrations can be replicated or reproduced with a high quality.
