Musical instrument equipped with a pedal, and method therefor

摘要

In a player piano, a position sensor is provided on an end portion of a lifting rail 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. A conversion section 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.

主权项

1. A musical instrument comprising:
a pedal configured to be displaceable in response to user's operation; a driven member configured to be displaceable in interlocked relation to displacement of said pedal; a control member configured to vary in its position relative to a sounding member, in response to displacement of said driven member, to thereby control the sounding member; a drive section configured to drive said driven member; a sensor configured to detect a position of said driven member; a first database storing therein correspondency relationship between positions of said pedal and positions of said driven member; a second database storing therein correspondency relationship between the positions of said pedal and control values; and a first output section configured to:
acquire, from said first database, a position of said pedal corresponding to a position of said driven member detected by said sensor;acquire, from said second database, a control value corresponding to the acquired position of said pedal; andoutput the acquired control value as pedal operation information.
