Effector for electronic musical instrument

摘要

An input waveform signal is converted in an A/D converter into a digital signal to be written in a waveform memory under control of a tone generation control unit. The written digital signal is read out from the waveform memory with a designated delay time. The input waveform signal and the digital signal read out from the waveform memory are converted in a D/A converter into analog signals which are fed through VCFs and VCAs 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 12a to 12d and VCAs 13a to 13d. Thus, it is possible to obtain a further effected sound.
