6: Impulse Expander
• 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” (≥ Page 123). All level and
balance settings relating to the Impulse Expander are also available in that
display page.
• Press the • button (“Set”) to go directly to the “Impulse Expander & Reso-
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.
● Density
≤ 0.146 msec … 20.77 msec.
Adjusts the density of the sound, and therefore its texture. Higher values produce
greater density.
● Dispersion
≤ 4.028 msec … 4.000 sec.
Determines the resonance time. The higher the value the longer the resonance.
• A high dispersion setting produces an early-reflections type reverberation effect.
● Roughness
≤ 0 … 16.
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.
