An automatic performance apparatus able to freely specify any two points A and B during the ALL repeat automatic performance. When the specified point A is closer to the start of the tune sequence being repeated than the point B, the apparatus repeats the performance between the two points A and B. When point B is closer to the start of the tune sequence, the performance skips from point B to point A.
A waveform reproduction apparatus providing an intuitive way to operate controllers corresponding to musical time quantities such as beats and bars. The apparatus includes a first storage means for storing a series of waveform data; an input means for inputting location information corresponding to movement on a surface; a second storage means for storing position information corresponding to delimiters between segments of the waveform data stored in the first storage means, the waveform data having been divided into a multiple number of segments, and for storing corresponding position information indicating a position along the surface indicated by the surface movement data; a position information generation means, wherein the position information for the waveform data stored in the first storage means is generated from the corresponding position information stored in the second storage means in accordance with the positions that are indicated by the location information input by the input means; and waveform formation means for forming musical tones from waveform data stored in the first storage means in accordance with pitches that correspond to pitch information that has been specified and corresponding to the position information generated by the position information generation means.
