05 - HF Damping
Range: 00 to 99
Increasing the value of this parameter will gradually filter out increasing amounts of high
frequency energy. Higher values yield an abrupt decay. This parameter controls the cut off of a
low pass filter in series with the decay within the definition.
06 - HF Bandwidth
Range: 01 to 99
This parameter acts as a low pass filter on the output of the plate reverbs, controlling the amount
of high frequencies present. The higher the setting, the more high frequencies are allowed to pass
through, offering a brighter ringing sound. Some interesting effects can be created by using a
mod controller over a large range.
07 - Diffusion 1
Range: 00 to 99
The Diffusion 1 parameter smears the input signal to create a smoother sound. Lower values will
cause impulse sounds to appear as a series of discrete echoes, while higher values tend to
increase the smear, making the echoes less apparent.
08 - Diffusion 2
Range: 00 to 99
This Diffuser, similar to and in series with the previous one, offers control over lower frequency
ranges. Plate Reverbs tend to sound metallic, and the diffusers help to smear the signal,
eliminating the metallic sound.
09 - Decay Definition
Range: 00 to 99
Controls the rate at which echo density increases with time. Higher values can cause the echo
density to build at a rate that exceeds the decay rate. Try to select the highest value that works
with your sound source for the best performance.
10 - Early Ref Level 1
11 - Early Ref Level 2
12 - Early Ref Level 3
13 - Early Ref Level 4
Ranges: -99 to +99
These parameters control four early reflection levels. Setting these levels to lower values will
produce a wetter sound. These four reflection levels are close to the input of the Definition.
14 - Left/Right Balance
Range: -99 to +99
This parameter controls the left/right stereo balance of the plate reverb signal. A setting of -99
would offer hard left, whereas a setting of +99 would offer hard right. A setting of +00 would
place the reverb in the center of the stereo spectrum.
15 - Mod1 Source
16 - Mod1 Destination
17 - Mod1 Param Range Min
18 - Mod1 Param Range Max
19 - Mod2 Source
20 - Mod2 Destination
21 - Mod2 Param Range Min
22 - Mod2 Param Range Max
