Electronic piano system accompanied with automatic performance function

An electronic piano system provides an automatic performance piano capable of automatically carrying out pre-recorded performance, plus a key-return speed detecting unit and/or a string-striking speed presuming unit. When a depressed key is released so that a key is to be returned to its original position, a key-return speed is occurred, which is detected by the key-return speed detecting unit. On the other hand, when the key is depressed so that a hammer strikes a string in order to generate the corresponding sound, a string-striking speed of hammer is occurred. Based on a detected key-striking speed, the string-striking speed presuming unit presumes the corresponding string-striking speed. Thus, by use of the detected key-return speed and/or presumed string-striking speed, the automatic performance can be carried out with high fidelity.

Sound board assembly for an upright piano

In construction of a sound board assembly for an upright piano, a unitary rectangular sound board support includes an outer bank corresponding to the conventional sound board base and a rearwardly stepped inner bank corresponding to the conventional base frame in order to remove necessity for surface finish and enable easy and free position adjustment at attachment of a sound board.
