Abstract:
1. An electronic keyboard instrument comprising: a keyboard including a plurality of keys a casing having said keyboard provided on a front side thereof, said casing having a surface extending in a direction from the front side toward a back side thereof; a plurality of speakers provided on said surface of said casing, said plurality of speakers including three or more speakers arranged substantially parallel to said keyboard on a front region of said surface, and at least one speaker provided at the back of the three or more speakers on said surface; a waveform memory having stored therein a plurality of waveform data sets each comprising waveform data of a plurality of channels, the waveform data of the plurality of channels being recorded waveform data based on a sound generated by a natural musical instrument having dampers to damp sound, the recorded waveform data being recorded via a plurality of sound pickup devices, corresponding to said plurality of speakers, set close to sounding members of the natural musical instrument arising the sound, said plurality of sound pickup devices positioned over the natural musical instrument analogously to the arrangement of said plurality of speakers on said surface, and three or more of said sound pickup devices, corresponding to said three or more speakers on said front region of said surface, being arranged substantially over said dampers of the natural musical instrument; a tone signal generation device that reads out, from said waveform memory, the waveform data of the plurality of channels corresponding to a tone designated by key depression on said keyboard and generates tone signals of the plurality of channels based on the read-out waveform data; and a supply device that supplies the tone signals of the plurality of channels, generated by said tone signal generation device, to respective ones of said speakers corresponding in positional arrangement to the plurality of sound pickup devices used for recording the waveform data of the channels.
