The BigVerb’s ER SPREAD, ER SHAPE and ER DIFFUSION controls
allow you to modify the build/decay of the early portion of the rever-
beration 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 reflection shapes can be found on Pg. 26.
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 simulat-
ed environment its reflectivity characteristics, and can be used to sim-
ulate the presence of nearly any type of large-area reflective surface
in a reverberant space, such as wood, carpet, glass, metal, etc.
