<p>An automatic performance apparatus is responsive to a manual play of an input implement 14K for producing either of an arpeggio performance and a pattern performance in a modified form. In the apparatus, a sequencer AR or PS is responsive to the manual play for generating a sequence of original note data representing either of the arpeggio performance and the pattern performance. An input device 15N1 is manually operable to set control parameters effective to control at least one of a tempo, a timing, a duration and a volume of the original note data. A play effector PE processes the original note data according to the control parameters to generate altered note data. A transposer TP shifts the altered note data by a predetermined interval to thereby generate shifted note data. A note effector NE generates additional note data in superposed relation to the shifted note data such that the additional note data has the same pitch as that of the shifted note data, or the additional note data has the same pitch name as that of the shifted note data but a different octave than the shifted note data, or the additional note data has a predetermined interval relative to the shifted note data. A tone generator TS is receptive of the shifted note data and the additional note data for generating corresponding musical tones to thereby provide the modified form of either of the arpeggio performance and the pattern performance. <IMAGE></p> |
