<P>PROBLEM TO BE SOLVED: To prevent the same information as the musical tone information to be sent to a mechanical player piano from being made into a sound volume '0' and sent to an electronic sound source device and from being erroneously recognized that a part of the musical tone information is dropped out and annihilated. <P>SOLUTION: A part of the musical tone information inputted to the musical tone controller unit 1 is sent to the mechanical player piano 2 and acoustic automatic playing is performed. The touch data TC (sound volume) of the same musical tone information as the above musical tone information is made into the '0' and is sent to the electronic sound source device 3, and the other musical tone information is also sent to the electronic sound source device 3. Since the information is delayed by the prescribed time at this time, the sound production/silencing of the electronic sound source device 3 and the sound production/silencing of the mechanical player piano 2 are prevented from being eventually offset. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
