ABSTRACT:
Performance data memory may be a conventional automatic performance memory which store plural kinds of automatic performance data such as song data for achieving an automatic melody performance and pattern data for achieving an automatic accompaniment. Designation information is set optionally which designates at least part of desired automatic performance data. Further, a custom performance data memory is provided for storing the designation information in combination in desired order. The designation information is sequentially read out from the custom performance data memory, and at least part of the automatic performance data designated by the designation information is read out from the performance data memory. Thus, an automatic performance in which at least parts of plural sets of the automatic performance data are sequentially combined is provided as a custom performance. Chord is detected on the basis of performance data for each of plural sections of a music piece, and the song performance data is converted to relative data in accordance with the detected data. For a reproductive performance, a desired chord is designated, the relative song performance data is reconverted in accordance with the designated chord, and tone is reproductively generated on the basis of the reconverted performance data.
