Musical tone synthesizing apparatus simulating interaction between plural strings

A music tone synthesizing apparatus comprising:

• a first loop means, including at least one delay element, for receiving and circulating an input signal so that a first resonance effect is imparted to said input signal so as to synthesize a first musical tone signal;
• a second loop means, including at least one delay element, for receiving and circulating said input signal so that a second resonance effect is imparted to said input signal so as to synthesize a second musical tone signal;
• introducing means for filtering said first musical tone signal and introducing said filtered first musical tone signal into sid second loop means;
• and
• adding means for adding outputs of said first and second loop means together to provide a synthesizes tone signal,
• whereby an interference with energy exchange occurs between the first and second loop means.

A musical tone synthesizing apparatus comprising:

• parameter generating means for generating a parameter corresponding to a musical tone to be generated;
• a plurality of loop means including (a) a first loop means including at least two delay elements, and at least one additional loop means including at least one delay element, each loop means for circulating a signal therein to form a tone signal, wherein a delay time by which a signal circulates through each loop means is controlled by said control parameter and set to correspond to a desired pitch of a tone signal to be formed in each loop means;
• connection means for connecting said plurality of loop means together such that a signal picked up from said first loop means is introduced into another said loop means;
• and
• excitation means for inputting a common excitation signal into both of said two delay elements of said first loop means and to at least one of the additional loop means to initiate circulation of a tone signal therein;
• wherein a synthesized musical tone signal is picked up from at least one of a loop means and said connection means.

a musical tone synthesizing apparatus comprising:

• generation means for generating an input signal;
• a first loop means, including at least two delay elements, for receiving an input signal at an input side of said two delay elements and circulating said input signal so that a first resonance effect is imparted to said input signal so as to synthesize a first musical tone signal;
• a second loop means including at least one delay element;
• introducing means for delaying said first musical tone signal and introducing said delayed first musical tone signal into said second loop means, said second loop means circulating said delayed first musical tone signal and imparting a second resonance effect thereto so as to synthesize a second musical tone signal;
• and
• adding means for adding outputs of said first and second loop means together to provide a synthesized tone signal,
• whereby an interference with energy exchange occurs between the first and second loop means.
