ABSTRACT:
Separately from an accompaniment style data memory having stored therein one or more accompaniment style data each including performance data for an automatic accompaniment, a modifying data memory is provided which has stored therein one or more modifying data sets each including style designating data for designating any of the accompaniment style data stored in said accompaniment style data memory and modification instructing data for modifying contents of the accompaniment style data designated by the style designating data. Desired one of the modifying data sets is selected and read out from the modifying data memory. One of the accompaniment style data is read out from the accompaniment style data memory in response to the style designating data of the read-out modifying data set read out by said readout section and its contents are modified in accordance with the modification instructing data of the read-out modifying data set, so as to generate modified accompaniment style data. When the modification instructing data indicates a modification for a performance time longer than one pattern cycle of the designated accompaniment style data, the designated accompaniment style data is repetitively reproduced to provide time-length-expanded accompaniment style data, and the time-length-expanded accompaniment style data is then subjected to modification in accordance with the modification instructing data.
