Abstract
A musical tone-synthesizing apparatus has a plurality of waveguide networks each including at least one waveguide, each of which has a closed loop in which a circulating signal circulates in response to an external excitation signal. The closed loop has an output through which the circulating signal is output as a waveguide output signal, and an input port through which a signal is input to be superposed on the circulating signal. A network output signal is formed based on the waveguide output signal. A connection means is connected to corresponding ones of the waveguide networks and carries out signal processing on the network output signal delivered from each of the corresponding waveguide networks, based on an external modulating signal, and inputs the resulting processed signal to the input port of the closed loop of each of the corresponding waveguide networks.
