307 Live Audio Effect Reference
Spread detunes the two resonators in relation to each other. Positive values raise the pitch of the
left resonator while lowering the pitch of the right one, while negative values do the opposite. At
0%, the resonators are tuned the same.
The resonance type chooser allows you to select from seven types of physically modeled reso-
nant 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 flat surface) of different materi-
als 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 resonators
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 components decay
slower (which simulates objects made of glass or metal). This parameter is not used with the Pipe
or Tube resonators.
