ABSTRACT:
A wave-shape generator advantageously used for generation of various wave-shape signals on electronic musical instruments comprises, as a substitute for multiple wave-shape memories needed in the conventional wave-shape generators, a combination of a single wave-shape memory with a weighting parameter signal generator. Modulation of the wave-shape signals via multiplication by corresponding weighting parameter signals enables formation of a wide variety of different wave-shape signals without enlargement in construction, the wave-shape signals being changeable even in a time-functional fashion too.
