| 摘要 |
The present invention provides an apparatus comprising digital means adapted to synthesise a digital waveform; conditioning unit means adapted to convert the digital waveform into an analogue waveform; and modulating means adapted to an analogue sound-carrying signal and said analogue waveform, and to modulate said analogue sound- carrying signal using the analogue waveform. In another aspect of the present invention there is provided a method for digitally controlling, continuously and in real-time, at least one analogue sound effect applied to an analogue sound-carrying signal from a musical source, which comprises the steps of synthesising a digital waveform; converting said digital waveform into an analogue waveform; modulating an analogue sound-carrying signal using said analogue waveform as modulating signal.
