Recording and reproduction of waveform based on sound board vibrations

A sound reproduction apparatus comprising:

• a sound board;
• an excitation device physically excitable in accordance with an input waveform signal and disposed in such a manner that physical vibrations generated by said excitation device are transmitted at least to said sound board;
• and
• a controller configured to receive a signal indicative of a vibration waveform of said sound board and input the received signal indicative of the vibration waveform to said excitation device, so that physical vibrations according to the input signal indicative of the vibration waveform are generated by said excitation device and a sound is generated by at least said sound board physically vibrating in response to the physical vibrations generated by said excitation device.

A computer-implemented method for storing performance information of a musical instrument, the musical instrument comprising:

• at least one performance operation key;
• at least one sounding member each provided in association with one of the at least one performance operation key;
• a sound board;
• at least one striking member each configured to physically vibrate one of the at least one sounding member in response to an operation of the at least one performance operation key;
