摘要： In order to eliminate the disadvantages due to varieties of a string-striking speed (i.e., dynamic characteristic) of a hammer, a hammering operation control unit is applied to a piano accompanied with an automatic performance function which can reproduce a musical performance recording in advance. Based on a detected string-striking speed of the hammer which is driven by the reference drive value predetermined to each key, the hammering operation control unit computes a deviation from the target string-striking speed corresponding to the reference drive value as a compensation value. Then, the newest computed compensation value is stored in a memory device or medium such as a floppy disk by periodically renewing the stored compensation value. Based on the stored compensation value, the string-striking speed of the hammer is to be compensated.

摘要： A grand piano generates acoustic tones through vibrations of strings and sound board so that the acoustic tones are converted to analog audio signals at recording points over the sound board, and a group of waveform data sets are produced from the analog audio signal through sampling and analog-to-digital conversion; when electronic tones are generated, delay parameters and volume parameters are determined on the basis of differences between the recording points and tone radiating points occupied by loud speakers, the sets of waveform data series are sequentially read out from the group of waveform data sets and are modified with the delay parameters and volume parameters so that the electronic tones become close to the acoustic tones.

摘要： Display device wherein change of the amount of light of the light-emitting elements caused by change of the number of light-emitting elements that emit light simultaneously is small. This display device includes a display panel having light-emitting elements arranged in matrix fashion; data lines for applying anode potential to light-emitting elements of the same column; scanning lines for applying cathode potential to light-emitting elements of the same row; and a control circuit that adjusts voltage between the anode and cathode of the light-emitting elements based on the number of light-emitting elements that emit light simultaneously. The control circuit suppresses changes of voltage between the anode and cathode of the light-emitting elements caused by a change in the number of light-emitting elements that emit light simultaneously. Accordingly, change of the amount of light of the light-emitting elements is suppressed.
