<P>PROBLEM TO BE SOLVED: To provide an arpeggio performing device by which real and various arpeggio performance can easily be conducted. <P>SOLUTION: Relative to a model pattern, phrase waveforms of real arpeggio performance conducted by a user are recorded, the phrase waveforms are analyzed while referring to the model arpeggio pattern, the phrase waveforms are divided into partial waveforms corresponding to each note and featured information such as pitch and sounding timing relative to the divided partial waveforms is extracted. The extracted featured information is stored corresponding to the phrase waveforms. The phrase waveforms corresponding to the featured information are individually corrected for every partial waveform and played back in accordance with the comparison between the featured information relative to the arpeggio performance to be played back and the corresponding model arpeggio pattern. Thus, real and various arpeggio performance can easily be conducted by using the phrase waveforms in which real arpeggio performance is recorded. <P>COPYRIGHT: (C)2007,JPO&INPIT |
