Abstract
A musical tone synthesizing device employing an operator, for generating musical tone signals by a modulation operation process. The device also employs a waveguide combined to the operator, for generating a reciprocating signal including a delay circuit for delaying the signal inputted into the waveguide feedback path, and for feeding back the output signal of the delay means to the signal, reciprocating within the waveguide.
Claims10
A musical tone synthesizing device comprising:
- modulation operation means for generating a modulated musical tone waveform signal in accordance with an inputted modulation signal;
- and
- a waveguide, coupled with said modulation operation means, for generating a signal reciprocating therein, comprising:
- delay means for delaying a signal inputted into said waveguide;
- and
- a feed back path for feeding back an output signal of said delay means to an input of said delay means to thereby form a closed loop.
