Physical Modeling: Advanced Models

More advanced physical models can be designed, based on the principles explained in the previous sections.


Resonant Bodies & Coupling

The simple lowpass filter in the example can be replaced by more sophisticated models. For instruments with multiple strings, coupling between strings can be implemented.
