ABSTRACT:
An auto-play apparatus has a ROM which pre-stores arpeggio pattern data including a sequence pattern, a trigger pattern, and a gater pattern, and a tone signal generation circuit for generating tones on the basis of these arpeggio pattern data. The apparatus can execute, in addition to a basic, monophonic arpeggio play according to depression of a keyboard unit, arpeggio plays in various play modes such as a polyphonic arpeggio play allowing to simultaneously produce two or more tones of those that form a chord, an arpeggio play allowing to simultaneously produce all the tones corresponding to ON keys, an arpeggio play allowing to gradually change the volume in a single pitch, and the like, thus broadening expression amplitude of performance.
