Selects the reverb type. Each room type has a different decay range (just as real rooms do), so changing TYPE
also changes the decay time of the room. Types are: Studio Room, Wood Room, Vocal Plate, Concert Hall,
Plate Reverb, Chamber, Cathedral, Arena, Cement Shelter, and Infinite Spring (for Reverbs), and: Flat,
Shelf, Decaying Linear, Decaying Logarithmic, Decaying Exponential, Decaying Sine, Reverse Linear,
Reverse Logarithmic, Reverse Exponential, Reverse Sine, Peaking Linear, and Peaking Exponential (for
Gated Reverbs).
Controls the number of discrete room wall reflections during the early portions of DECAY. Higher settings
produce more reflections while low settings yield fewer initial wall echoes. Use this control in conjunction with
DISPERSION to build or reduce the thickness of early reflection clusters heard near the beginning of the rever-
beration. Ranges from 0% to 99%.
Controls the distance (time) between the echoes set by DENSITY. If DENSITY is set low and DISPERSION is set
high, the initial room echoes. Dispersion can be heard as discrete echoes followed by smoother room reverbera-
tions. Set DISPERSION low for a dense cluster of reflections during the early portions of DECAY. Ranges from 1
to 10.
Simulates the presence of different room materials by controlling the smoothness of reverberations through the
course of DECAY. Low DIFFUSION settings are great for simulating hard, flat surfaces while higher DIFFUSION
settings can be used to simulate the presence of irregular surfaces in the room such as natural rock masonry or
man-made diffusers. Unlike flat surfaces, these materials reflect (diffuse) the sound in many directions because of
the irregularity of the surfaces themselves. This builds smoothness over the reverb progression. Ranges from 0%
to 99%.
Selects which crossover type will be used for the Primary Secondary reverb stages. The two crossover types are
High Pass (HP) and Low Pass (LP).
Selects the frequency where the crossover begins to function. Ranges from 25Hz to 20kHz.
These two Parameters allow the crossover to be turned On or Off for each reverb stage. When Off, that particular
stage will be full bandwidth, otherwise its frequency response is limited by the X-Over Type and Frequency
parameters.
Adjusts how quickly the room absorbs the high-frequency reverberations. In a real room, absorptive materials can
be used to dampen the natural high-frequency reverberations of the room. High settings of DAMP cause the
reverberations to darken tonally and become less defined over the course of DECAY. Low settings cause less
dramatic room effects on the tone of the reverberations. Ranges from 1 to 10.
Selects the frequency above which all frequencies are rolled off. This control can be used to darken the response
of bright-sounding gated reverbs. Ranges from 100 Hz to 8 kHz in the Gated Reverb and from 100 Hz to 20 kHz
in the Stereo Gated Reverb.
Controls the length of the gated reverb in milliseconds (much like the DECAY control of a normal reverb).
Ranges from 25 milliseconds to 300 milliseconds in the Gated Reverb and from 500 milliseconds in the Stereo
Gated Reverb.
Cross-mixes reverberations from the left side into the right side and vice-versa. This can be used to increase the
realism of the simulated room by adding reverberations from different parts of the room to each channel. Ranges
from 0% to 99%.
Adjusts the amount of BLEND for the Primary and Secondary reverb stages. See BLEND above for a complete
parameter description.
Controls the length (RT60) of the room reverberations. This one control could have been divided among Size
