Abstract (en)
[origin: EP0322871A2] An effect tone of an appropriate pattern such as the murmur of a brook or songs of birds is generated at an arbitrary timing with a simple operation of keyboard (11). Since the tone volume of an effect tone can be gradually increased or decreased by using fade in/ fade out key and the tone volume can be independently controlled in units of channels (15a, 15b) using a plurality of channels, the effect of the effect tones can be improved.
