The RV ROOM SIZE control is the master control for the apparent room size. The RV RTMID
and RV RTBASS Parameters vary in relation to the setting of the RV ROOM SIZE. Meaning,
that as RV ROOM SIZE is modified, the RV RTMID and RV RTBASS Parameters change to
correspond with the selected room size. These values are calculated automatically, and the rela-
tive settings of RV RTMID and RV RTBASS remain the same. On the other hand, the RV
ROOM SIZE Parameter does not vary when RV RTMID or RV RTBASS are modified.
These controls, in conjunction with the RV X OVER FREQUENCY, RV DIFFUSION, RV
HI-FREQ DECAY, RV HI-FREQ ROLLOFF, RV MID LEVEL, and RVBASS LEVEL controls,
give your simulated environment its reflective characteristics, and can be used to simulate the
presence of any large-area reflective surface in a reverberant space, such as wood, carpet, glass,
metal, etc.
Adding more sonic flexibility to the GSP-2101 Artist's GigaVerb is a 1-band parametric EQ
with adjustable Q control (more on Q in the Equalizer section) and ±15 dB of boost/cut. This is
included as part of the GigaVerb Module, giving more tonal control over reverberation than any
other processor.
Reverb Parameters and their functions are as follows:
Effect On / Off: Turns the Module on or off. When the Module is turned off, its
Parameters are not displayed and, signal will not continue to pass through the module.
To see the Parameters, you must turn the Module on.
ER Pre-delay Time: Controls the length of time before the early reflections are heard.
Ranges in milliseconds from 0 to 100.
ER Spread: Controls the length of time the early reflections occur. Low settings yield
dense, smooth clusters of early reflections, while higher settings spread the same number
of reflections out over a longer period of time. Ranges from 20 to 600 milliseconds.
ER Shape: Controls the shape of the early reflection envelope. There are 16 different
early reflection envelope shapes. See fig. 3-6. The numbers across the top of each enve-
lope shape graphic represents the level (relative to unity gain) of the signal at each
point in the envelope.

Section 3 - Editing Effects
The GigaVerb's ER SPREAD, ER
SHAPE, and RV ROOM SIZE con-
trols let you modify the build/decay
of the early portion of the reverbera-
tion envelope and the relative rever-
beration time of the midrange reverb
frequencies.
The ER SHAPE Parameter controls
the shape of the early reflection
envelope, and ER SPREAD sets the
time over which this early reflection
shape is achieved. A chart showing
all 16 early reflection shapes can be
found on Pg. 24.
