• This display will not appear — "Impulse Expander is not used"
will appear — if the "IE on/off" block in the "Impulse Expander &
Resonator Setting" page is turned "off" (
balance settings relating to the Impulse Expander are also available in that
display page.

nator Setting" page.
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)
• If the IE & RSN SETTING page "Dry Level" parameter is set to a high
level, phase cancellation between the dry and wet signals can change the
sound of the Impulse Expander effect.
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.
