<P>PROBLEM TO BE SOLVED: To regenerate grand piano sound with reality. <P>SOLUTION: Electronic piano 1 includes loudspeakers 4a, 4b and 4c arranged on its front side region and another loudspeaker 4d provided at a back position of the electronic piano 1. Waveform memory 21 provided in a tone generator section 20 has prestored therein sets of four-channel-sampled waveform data, each of the sets corresponding to a tone. The four-channel waveform data are data recorded from a grand piano via four microphones installed at sampling positions corresponding to the loudspeakers 4a, 4b and 4c, and the loudspeaker 4d. The microphones are installed with the on-microphone setting in which the microphones are positioned close to a sounding source. In response to depression of a key, any one of the sets of four-channel waveform data, corresponding to a tone pitch designated by the key depression, is read out from the waveform memory 21, so that the four-channel waveform data are supplied in parallel to the loudspeakers 4a, 4b and 4c and the loudspeaker 4d. <P>COPYRIGHT: (C)2010,JPO&INPIT |
