ABSTRACT:
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.
