1. An effect tone generating apparatus, comprising:
- waveform generating means for generating a plurality of waveform data constituting an effect tone representing a scene;
pattern generating means for generating at least first and second effect tone patterns indicating generation timings of the waveform data from said waveform generating means constituting the effect tone;
manually operative means for manually selecting one of the first and the second effect tone patterns; and
pattern selections means, for, when the second effect tone pattern is selected by said manually operative means during generation of an effect tone based on the first effect tone pattern output from the pattern generating means, starting generation of an effect tone based on the second effect tone pattern output from the pattern generating means, and for, when a pattern end of the second effect tone pattern is detected, restarting generation of the effect tone based on the first effect tone pattern.

Abstract
An effect tone generating apparatus can generate an effect tone of an appropriate pattern such as the murmur of a brook or songs of birds, at an arbitrary timing with a simple operation. Since the tone volume of an effect tone can be gradually increased or decreased and the tone volume can be independently controlled in units of channels using a plurality of channels, the audible impressions created by the effect tones can be improved.
