A piano selectively playable in normal and soft modes has multiple piano keys and actions, including a wippen assembly, and multiple piano hammers. A soft mode pedal system includes soft and ultra-soft mode pedals, and a hammer rest rail mounted for movement between normal and soft mode positions. A piano key lift rail is mounted for movement between a normal mode position spaced from lifting contact with the keys and a soft mode position in contact with and lifting the keys and the wippen assemblies. A soft mode pedal linkage assembly between the soft and ultra-soft mode pedals and the hammer rest and piano key lift rails causes movement of the hammer rest rail, piano hammers, the piano keys, and the wippen assemblies upon actuation of the soft mode pedal between normal mode position and soft and ultra-soft mode positions. |

1. A piano selectively playable in a normal mode and in two or more soft modes comprises:
a set of multiple piano keys; a set of multiple piano actions associated with said multiple piano keys, each said piano action including a piano wippen assembly actuated by depression of a corresponding said piano key; a set of multiple piano hammers, each said piano hammer mounted for rotating movement and defining a forward throw direction toward at least one corresponding piano string, each said piano hammer being driven by a corresponding said piano wippen assembly to transfer force applied to an associated said piano key; and a soft mode pedal system comprising:
a soft mode pedal and an ultra-soft mode pedal;a hammer rest rail mounted for movement among a normal mode position with said set of multiple piano hammers disposed at rest at a spaced distance from corresponding piano strings, a soft mode position with said set of multiple piano hammers moved into at rest positions closer to the corresponding said piano strings, relative to the normal mode position, and an ultra-soft mode position with said set of multiple piano hammers moved into at rest positions closer still to the corresponding said piano strings relative to the normal mode position;a piano key lift rail mounted for movement among a normal mode position spaced from lifting contact with piano keys of said set of multiple piano keys, a soft mode position disposed in contact with and lifting said the piano keys along with said piano wippen assemblies, and an ultra-soft mode position disposed in contact with and further lifting said the piano keys along with said piano wippen assemblies; anda soft mode pedal linkage assembly in communication between said soft mode pedal and said ultra-soft mode pedal and said hammer rest rail and said piano key lift rail, wherein actuation of said soft mode pedal causes movement of said hammer rest rail, along with said piano hammers, and causes movement of said piano keys, along with said piano wippen assemblies, between the normal mode position and the soft mode position, and wherein actuation of said ultra-soft mode pedal causes relatively further movement of said hammer rest rail, along with said piano hammers, and causes relatively further movement of said piano keys, along with said piano wippen assemblies, between the normal mode position and the ultra-soft mode position. |
