Abstract
An auto-play apparatus having an auto-play data memory for storing a note data string of an auto-accompaniment pattern, and a tone generator for generating tones on the basis of the note data string read out from the auto-play data memory. The auto-play apparatus includes an intonation pattern memory for storing intonation patterns of a plurality of levels corresponding to different degrees of tone-up of a performance. The intonation value is changed upon operation of an operation unit, and a note data string is read out from the auto-play data memory on the basis of intonation pattern data corresponding to the new intonation value. The readout note data string is supplied to the tone generator. The intonation pattern data of different levels includes at least designation information for designating different read positions in the auto-play data memory, and different tone volume information, different tone color information, and different instrument information to be provided to the readout note data. The intonation pattern data is partially rewritten in a data edit mode, thus changing the tone-up pattern of an accompaniment.
