摘要： A tone generation control unit has four waveform read/write channels for selectively reading or writing data in a waveform memory. A plurality of waveform signals stored in the waveform memory are converted into analog signals to be subjected to timbre and tone volume control through voltage-controlled filters and voltage-controlled amplifiers before being fed to a mixing adder. An output signal of the mixing adder is converted into a digital signal which is stored in the waveform memory again through processing of the tone generation control unit.

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.
