Recently, a nonlinear discrete-time model that simulates a vibrating string exhibiting tension modulation has been presented. This paper elaborates the previous model by taking into account two phenomena: 1) coupling of the tension modulation force to the instrument body and 2) feedback of the tension modulation force to the vibrating string. The two phenomena are investigated by analysis of plucked string instrument tones. Sound synthesis examples are available at www.acoustics.hut.fi/ ttolonen/icmc99/ including tones by the proposed model, and by a linear model and a previous nonlinear model. The examples show that tension modulation coupling phenomena are important for the quality of synthesized tones and that the tones by the presented model are more natural than with the previous models.
