The BigVerb’s ER Spread, ER Shape and ER DIFFUSION controls let
you modify the build/decay of the early portion of the reverberation
envelope and the relative reverberation time of the midrange reverb
frequencies. The ER Shape Parameter controls the shape of the early
reflection envelope. The ER SPREAD sets the time over which this
early reflection shape is achieved, and the ER diffusion controls the
smoothness of the early reflection. A chart showing all 10 early reflec-
tion shapes can be found on the following page.
The Rv Size control is the master control for the apparent room size.
The RV RT60 Parameter varies in relation to the setting of the RV
Size. This means that as RV Size is modified, the RV RT60
Parameter changes to correspond with the selected room size (the RV
RT60 value is calculated automatically). The RV Size Parameter, on
the other hand, does not vary when RV RT60 is modified.
These few controls, in conjunction with the RV Diffusion, RV Hi-Freq
Decay, and RV Hi-Freq RollOff controls, give your simulated environ-
ment its reflectivity characteristics, and can be used to simulate the
presence of nearly any type of large-area reflective surface in a rever-
berant space, such as wood, carpet, glass, metal, etc.
Reverb Parameters and their functions are as follows:
Reverb On / Off.............Turns the Module on or off. When Modules are
turned off, their Parameters disappear from the
Parameter menu. To see the Parameters, you
must turn the Module on.
ER Predelay..................Controls the length of time before the early
reflections are heard. Ranges in milliseconds
from 0 to 100. (ER settings in BigVerb only.)
ER Spread.....................Controls the length of time over which the
early reflections occur. Low settings yield a
dense, smooth cluster of early reflections while
