PURPOSE:To give a sostenute effect equivalently to an actual piano by controlling the damping time of a musical sound related to a released key longer when information regarding the released key is stored in an information storing means for sostenute and shorter when the information is not stored. CONSTITUTION:Upon releasing a key from a pressed state on a keyboard 11, the damping time of the musical sound related to the key is controlled longer when information regarding the key is stored in an information storing means (microcomputer section) 15 for sostenute and shorter when the information is not stored. Therefore, even when the same key is repeatedly operated on the keyboard 11 or a key which is already canceled from an assigned state is newly pressed, a sostenute effect is added to the musical sound related to the key depressed when an operator 13 is operated. Thus the sostenute effect can be made equivalent to an actual piano. |
