The resonance type chooser allows you to select from seven types of physically modeled
resonant objects:
Beam simulates the resonance properties of beams of different materials and sizes.
Marimba, a specialized variant of the Beam model, reproduces the characteristic tuning
of marimba bar overtones which are produced as a result of the deep arch-cut of the
bars.
String simulates the sound produced by strings of different materials and sizes.
Membrane is a model of a rectangular membrane (such as a drum head) with a variable
size and construction.
Plate simulates sound production by a rectangular plate (a at surface) of different
materials and sizes.
Pipe simulates a cylindrical tube that is fully open at one end and has a variable
opening at the other (adjusted with the Opening parameter.)
Tube simulates a cylindrical tube that is fully open at both ends.
The resonator quality chooser controls the tradeoff between the sound quality of the res-
onators and performance by reducing the number of overtones that are calculated. Basic
uses minimal CPU resources, while Full creates more sophisticated resonances. This
parameter is not used with the Pipe or Tube resonators.
The Decay knob adjusts the amount of internal damping in the resonator, and thus the decay
time.
The Material knob adjusts the variation of the damping at different frequencies. At lower
values, low frequency components decay slower than high frequency components (which
simulates objects made of wood, nylon or rubber). At higher values, high frequency com-
ponents decay slower (which simulates objects made of glass or metal). This parameter is
not used with the Pipe or Tube resonators.
The Radius parameter is only available for the Pipe and Tube resonators. Radius adjusts the
radius of the pipe or tube. As the radius increases, the decay time and high frequency sustain
both increase. At very large sizes, the fundamental pitch of the resonator also changes.
The Decay and Material/Radius parameters can also be controlled with the X-Y controller.
