摘要： An automatic player piano has a feedback control loop (64) for each of the black/ white keys (72/ 74); the controller (100) firstly determines a reference trajectory, i.e., a target key position (rx) varied with time for each key (72/74) to be moved in the playback, and calculates a target key velocity (rv), and compares a true key position (yx) reported from a key sensor (27) and a true key velocity (yv) calculated from the true key position with the target key position (rx) and target key velocity (rv) for optimizing the duty ratio of the driving signal; the positional difference (ex) and the velocity difference (ev) are independently multiplied by a positional gain (kx) and a velocity gain (kv) so as to determine the optimum duty ratio; since the ratio of the velocity gain (kv) to the positional gain (kx) is 1 to 3, the key travels along the reference trajectory without oscillation and overshoot.

摘要： In a player piano, a position sensor (555) is provided on an end portion of a lifting rail (8) for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer (1023). A conversion section (1021) converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information.

摘要： An automatic playing system is independent of acoustic pianos (2), and is designed to perform music tunes expressed by sets of MIDI music data codes on the acoustic pianos (2); since the acoustic pianos (2) have their own individualities, control parameter tables, which were prepared through experiments on a standard piano, are not optimum for most of the acoustic pianos due to the individualities; the automatic playing system can tailor the control parameter tables defining relation between the magnitude of driving signal (S5) and the MIDI velocity and relation between the magnitude of driving signal (S5) and time lag from the supply of the driving signal (S5) and the collision between the hammers (22) and the strings (23) for each sort of acoustic pianos before the automatic playing so that the automatic playing system reproduces the music tunes at high fidelity regardless of the sort of acoustic pianos.

摘要： An automatic player piano is a combination between an acoustic piano (1) and an automatic playing system (10), and a grand piano and an upright piano are used as the acoustic piano; the grand piano has action units prompter than action units of the upright piano so that a half-stroke recorded through the grand piano is not reproducible by the upright piano; the automatic playing system (10) causes the hammers (3) to rotate toward the strings (4) without any escape, thereby compensating the poor promptness with the short keystroke of the keys (1b, 1c) until the rotation of hammers (3).

摘要： A speed detecting apparatus for a keyboard musical instrument is provided for accurately detecting the speed of pivotal movements of a hammer and a key even if a shutter implies errors in its attachment, without affected by such errors. The speed detecting apparatus for a keyboard musical instrument comprises a pivotable key (4), a hammer (5) pivotably supported by a fulcrum and configured to pivotally move in association with a pivotal movement of the key, a shutter (6) integrally attached to the hammer, a plurality of detectors (7,8), each having a light emitter and a light receiver for receiving light emitted from the light emitter, arranged on one and the other sides of the pivotal movement path of the shutter, and a CPU for detecting a pivot speed of the hammer in response to timings at which the shutter opens and closes the light paths of the light of the plurality of detectors when the hammer pivotally moves. The plurality of detectors have detection points on respective light paths of the light from the light emitters, and are arranged such that the detection points are positioned on an arc centered at the fulcrum of the hammer.

摘要： A method and apparatus for actuating solenoids (34) in an electronic player piano where a Musical Instrument Digital Interface (MIDI) velocity value is translated to a solenoid driving signal, a counter is activated by the solenoid driving signal, and a solenoid (34) is energized from the counter according to the solenoid driving signal (28). A central processing unit (CPU, 16) reads the MIDI data from a digital data storage device (12), and selects the corresponding solenoid driving parameters from a look-up table stored in read only memory (ROM, 18). The solenoid driving parameters are converted into a pulse width modulation (PWM) waveform by a driving circuit (26) containing counters. The PWM signal (32) is sent to the gate of a field effect transistor (FET, 30) switch connected to the solenoid (34) and the solenoid (34) is energized by the FET (30) according to the PWM signal (32).

摘要： An elongated lifting rail (8) is displaceable to collectively pivot a plurality of damper levers (91). An actuator (552) is provided beside or underneath the lifting rail for automatically displacing the lifting rail. The lifting rail is displaced, in response to driving of the actuator, to displace the damper levers so that the dampers (6) are moved away from contact with sounding members (4). Further, a position sensor (555) is provided for detecting a displaced position of the lifting rail, so that position data detected by the position sensor is used for operating position control and/or operating position recording of the dampers.
