Wires attached at nodes will have no effect on the vibration of the resonator or the overall filter response.

The filter response varies constantly with time and is not linked to playing dynamics.

In principle, any non-zero frequency point on the filter response could be used as a reference for the prototype design.

The result of this design is a filter response which falls very rapidly past the cut-off frequency.

Synthesis methods allow better control of the precise filter response.

The overall filter response is then found from the combined scattering matrix of all the individual element matrices.

This causes the filter response to deviate from the theoretical.

The shape of the filter response provides even fewer degrees of design freedom.

In the transition region the filter response will have a slope of up to 6 dB per octave.

So while stopband impedance mismatch may be severe, it has only limited effect on the filter response.
