The Impulse Expander works in conjunction with the Resonator, described below, to
simulate the effect of an instrument's resonant cavity or sound box. It can also be used to
simulate the acoustic environment in which the instrument is played.

Equalizer)
Density
Adjusts the density of the sound, and therefore its texture. Higher values produce
greater density.
Dispersion
Determines the resonance time. The higher the value the longer the resonance.
A high dispersion setting produces an early-reflections type reverberation effect.
Roughness
This parameter imparts a "roughness" to the overall frequency response in the form
of steep peaks and dips in the response. The higher the value the greater the roughness.
