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： A reproduction apparatus 2 collects sounds on which spread codes are superimposed with a microphone 20 to calculate correlation values between the collected sound signals and the same spread codes as those of an apparatus which performed the superimposition to identify content reproduced by a reproduction apparatus 1 in accordance with the intensity of the peaks of the calculated correlation values. A control portion 22 identifies content which is correlated with the identified content and is necessary for the reproduction apparatus 2. The control portion 22 reads out the identified content data from a content data storage portion 25 to output the musical score data and the audio data to a display portion 23 and a reproduction portion 26, respectively. The display portion 23 displays the input musical score data on a screen, while the reproduction portion 26 reproduces the input audio data to generate sound signals.

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.
