Special effects device for an electronic musical instrument.

摘要

An input waveform signal is converted in an A/D converter (6) into a digital signal to be written in a waveform memory (7) under control of a tone generation control unit (8). The written digital signal is read out from the waveform memory (7) with a designated delay time. The input waveform signal and the digital signal read out from the waveform memory (7) are converted in a D/A converter (l0) into analog signals which are fed through VCFs (l2a-l2d) and VCAs (l3a-l3d) so as to be sounded. Further, in the above arrangement the timbre and tone volume controls are done independently for the individual waveform read/write channels through VCFs (l2a-l2d) and VCAs (l3a-l3d). Thus, it is possible to obtain a further effected sound.
