The actual feedback level is modified by the Master Echo Feedback param-
eter, if present. The master value is a percentage (0-100%) that is applied to
the Echo Feedback level.
Feedback Diffusion
Feedback Diffusion is similar to Input Diffusion, except that it is applied to
a delayed signal that is being added back into the input.
Feedback Level
This parameter determines the feedback level for a particular voice. It is con-
trolled independently of the voice’s output level.
Feedback Pan
Routes the post-filter delay voice back to the inputs of the delay lines.
Frequency
This parameter lets you set the cutoff frequency of the multimode filter. The
audible effect of this is determined by the Type parameter.
Front Early Level
This parameter acts as a master control for any early signals going to the out-
put channels. Early signals include echoes, reflections, and the room reflec-
tion patterns.
Infinite
This parameter captures the reverb tail as an infinite loop. This may be use-
ful in music, where a note or chord can be extended. It is also useful in post-
production for creating ambience backgrounds.
Input Level
Input Level controls the amount of signal admitted into the process from a
single input channel.
Input Pan
Routes the signal from an input channel into the algorithm in such a man-
ner as to alter its apparent location.
Level
This parameter acts as a master control for reverb signals going to the output
channels. It is used for all reverbs.
LFO Rate
Set the speed of an LFO in Hz.
LFO Waveform Type
Set the shape of the wave the LFO will follow.
Master Echo Delay
Controls all echo voices in the algorithm. Each echo delay has its nominal
time adjusted by this percentage.
Master Echo Feedback
Controls all echo voices in the algorithm. Each echo feedback has its nomi-
nal gain adjusted by this percentage.
