  • Automatic player piano equipped with soft pedal, automatic playing system and method used therein
    Patent number: 7960629
    Abstract: An upright piano is equipped with a soft pedal, and a player makes the hammer stroke shorter by depressing the soft pedal; while a user is reproducing a music tune by means of an automatic player piano fabricated on the basis of the upright piano, the keys are servo controlled on the basis of a position difference of keys between target values and actual values and a key velocity difference, and the duty ratio of driving signal, which is supplied to solenoid-operated key actuators for the keys, are determined on the basis of multiplications between the position difference/key velocity difference and a position gain and a velocity gain; the value of position gain is reduced on the condition that the soft pedal is depressed for preventing the playback from an unintentional loud tone or tones.

  • Automatic player musical instrument, automatic player incorporated therein and method used therein
    Patent number: 7521627
    Abstract: An automatic player piano is fabricated on the basis of an acoustic piano, and an automatic player is expected to give rise to key motion for reenacting performance with solenoid-operated key actuators; since the hammers of acoustic piano are different in mass, the load against the key motion is also different among the keys; while the motion controller is forcing the keys to travel on reference key trajectories through a servo control loop, the motion controller takes the pitched part into account, and selectively accesses control parameter tables so as to read out the approximate control parameters for the individual keys, whereby the hammers surely reach the target final hammer velocity before striking the strings.
