Conclusions

It is important to understand that a musical instrument is not a stable or balanced system in reality. Its behavior and responsiveness depends on various factors and consequently a Physical Model should not be framed as a squared box or a fixed parametric system. The degree of musical expression is proportional to the number of degrees of freedom provided by the Physical Model. Nevertheless the complexity of the model is inverse to its degrees of freedom. Therefore, the more flexible the model the harder to understand and handle. More information and parameter descriptions and documentation in plain vanilla is needed from its designers. In particular interval sets, boundary conditions and valid parameters.
