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,
and modulated by note pitch and velocity via the sliders below the X-Y panel.
Ratio is only available for the Membrane and Plate resonators, and adjusts the ratio of the
object's size along its x and y axes.
The Brightness control adjusts the amplitude of various frequency components. At higher
values, higher frequencies are louder. This parameter is not used with the Pipe or Tube
resonators.
The Inharmonics knob adjusts the pitch of the resonator's harmonics. At negative values,
frequencies are compressed, increasing the amount of lower partials. At positive values,
frequencies are stretched, increasing the amount of upper partials. This parameter is not
used with the Pipe or Tube resonators. Inharmonics can also be modulated by velocity via
the slider below the knob.
Opening, which is only available for the Pipe resonator, scales between an open and closed
pipe. At 0%, the pipe is fully closed on one side, while at 100% the pipe is open at both
ends. This parameter can also be modulated by velocity via the slider below the knob.
The Listening L and R controls adjust the location on the left and right resonator where the
vibrations are measured. At 0%, the resonance is monitored at the object's center. Higher
values move the listening point closer to the edge. These parameters are not used with
the Pipe or Tube resonators, which are always measured in the middle of their permanently
open end.
The Hit knob adjusts the location on the resonator at which the object is struck or otherwise
activated. At 0%, the object is hit at its center. Higher values move the activation point
closer to the edge. This parameter is not used with the Pipe or Tube resonators. The Hit
position can also be randomized by increasing the value of the Rd. (Random) slider below
the knob.
