摘要： 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 into a memory for each of the keys. 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. In response to an operation of a key, a sound board vibration waveform corresponding to the operated key is read out from the memory, and the excitation device is driven in accordance with the read-out waveform signal so that the sound board is vibrated.

摘要： 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.

摘要： A pitch information generation device includes a first envelope generator configured to generate, with regard to a first sound range, a first envelope that attenuates at a first rate of change from a detected value corresponding to a peak in the sound signal, a second envelope generator configured to generate, with regard to a second sound range, which includes a sound range of higher frequency than the first sound range, a second envelope that attenuates from a detected value corresponding to a peak in the sound signal at a second rate of change. The second rate of change is greater than the first rate of change. A pitch information identifier is configured to identify the pitch information based on the first envelope and the second envelope.
