Musical tone synthesis system having shortened excitation table

摘要

A tone synthesis system employs a filtered delay loop which is excited by an excitation signal. The excitation signal corresponds to a partial impulse response of a body filter to the system which is to be simulated. Additional components of the impulse response of the body filter are imparted to an output from the filtered delay loop. High quality tone synthesis can be achieved without the necessity of providing a complicated body filter.
