摘要： For each key and without damping action of dampers deactivated by a damper pedal, loads imposed on a portion of the key acting on the damper are measured while the key is moved over one stroke in at least one of key-depressing and key-releasing directions, in association with a plurality of stroke positions in the one stroke of the key. For each key, a key-damper half region is identified on the basis of relationship between the individual stroke positions and the measured loads corresponding to the stroke positions. Then, on the basis of the key-damper half regions identified for the individual keys, a half point is determined separately for each of the keys, or a half point common to a group of a plurality of the keys is determined.

摘要： In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to an excitation unit provided on a soundboard. In response to a mechanical vibration generated by the excitation unit, the soundboard is vibrated so as to generate an acoustic vibration sound corresponding to the operated key. The excitation unit is supported by a supporting unit such that less or no load of the excitation unit except a vibration member vibrated in response to the drive signal is applied to the soundboard. Thus, only a load of the vibration member which is a very light portion of the excitation unit is applied to the soundboard, thereby vibration characteristics of the soundboard being hardly affected. When a sound damping mode is selected, a stopper is permitted to prevent a hammer from striking a sounding body.

摘要： A key depression (i.e., string striking) is performed while a pedal is kept at a set non-key-depressed-state corresponding position (a rest position of a hammer). A string striking velocity immediately before string striking and a string releasing velocity immediately after the string striking are detected, and a coefficient of rebound is calculated on the basis of the detected velocities and stored in association with the current value of the rest position of the hammer. Similar operations are repetitively performed with individual ones of different rest positions of the hammer, wherein each of the different rest positions of the hammer corresponding to each of a plurality of stroke positions within one stroke of the pedal. Thus, a distribution curve of the coefficients of rebound detected in association with the plurality of stroke positions is obtained and a half point of the pedal is identified based on the distribution curve.

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.
