Musical tone synthesizing apparatus including modulator on its non-linear/linear outputs

A musical tone synthesizing apparatus comprising:

• parameter generating means for generating a first parameter and a second parameter which control a characteristic of a musical tone to be generated;
• non-linear operation means for producing a non-linear signal in accordance with said first parameter;
• linear operation means connected to receive the non-linear signal from said non-linear operation means and for conducting a linear operation on said non-linear signal in accordance with said second parameter to produce a modified non-linear signal, wherein said non-linear operation means further receives said modified non-linear signal, conducts a non-linear operation on said modified non-linear signal in accordance with said first parameter and produces a revised non-linear signal so as to supply said revised non-linear signal to said linear operation means as said non-linear signal;
• and
• modulation operation means for performing a modulation operation using said non-linear signal from the non-linear operation means and said modified non-linear signal from the linear operation means and for producing the modulated signal as said musical tone signal.
