ABSTRACT:
In a music apparatus, an operator panel designates a first style of automatic play. A tone generator sequentially generates musical tones to produce the automatic play in the designated first style. A DSP applies a first effect to the musical tones in matching with the first style of the automatic play. A CPU operates when the operator panel commands a style change from the first style to a second style during the course of the automatic play for controlling the tone generator to switch the automatic play to the second style. The CPU further operates when the style change necessitates an effect change from the first effect to a second effect matching the second style in a transient period for controlling the DSP before the controlling of the tone generator to complete the effect change within the transient period so that the DSP can apply the second effect to the musical tones timely when the automatic play is switched from the first style to the second style.
