KEYBOARD MUSICAL INSTRUMENT, AND METHOD FOR REPRODUCING HALF PERFORMANCE OF PEDAL OR KEY DAMPER ON KEYBOARD MUSICAL INSTRUMENT

摘要

One half region or point is determined based on a plurality of half pedal regions or points, in a stroke of a pedal, specific to the individual dampers corresponding to keys. When a pedal reproduction event instructs a half region or point, a target trajectory of the stroke of the pedal is generated such that the pedal is positioned at the half region or point specific to the key, and the pedal is driven on the basis of the target trajectory. For each key, a key-damper half region or point in a stroke of the key is identified in advance. In response to a key reproduction event instructing half control, a target trajectory of the stroke of the key is generated such that the key is positioned at the key-damper half region or point specific to the key, and the key is driven based on the target trajectory.
