Category (Room)
This parameter lets you select a specific category from which a room
response may be chosen. Changes here have a direct effect on the Pattern
Selector parameter.
Chorus Depth (Concert Hall)
This parameter controls the amount of randomization of the chorus tap.
Higher values are generally preferred in order to minimize reverb coloration.
Pitch effects may result and are closely tied to the Reverb Chorus Rate
parameter.
Chorus Rate (Concert Hall)
This parameter controls the rate at which the reverb chorus is run. Low
values may cause a barely-noticeable undulation. Higher values will cause
noticeable wobble in fixed-pitch instruments such as piano. It is closely tied
to the Reverb Chorus Depth parameter.
Definition
Definition controls the density of some reverbs. Higher values result in lower
density.
Delay Feedback Master
Controls all delays in the algorithm. Each voice has its nominal feedback
gain adjusted by this percentage.
Delay Level Master
Controls all delays in the algorithm. Each voice has its nominal gain value
adjusted by this percentage.
Delay Time (Echo Delay)
Delay time defines the time offset of a delay voice in milliseconds or
in fractions of tempo (quarter note, eighth note), which is defined by
the tap tempo or by midi tempo. It is used in many of the algorithms,
not just the delays. In all cases, it does the same thing.
Delay Time Master
Controls all delays in the algorithm. Each voice has its nominal delay time
adjusted by this percentage.
Delay wander
This parameter determines the amount of additional delay that the LFO
process can add to a voice’s offset.
Diffusion
Input diffusion is the first part of processing for any signal entering a reverb
or delay. It can be described as a smearing or softening of the signal and is
typically used to lessen the impact of strong transients.
Bass Crossover (Bass XOver) (Room)
Thus parameter is closely tied to the Early Bass Boost parameter. It repre-
sents the frequency below which early bass boost has an effect.
Feedback
This controls the amount of echo output that is fed back to the input of the
echo buffer.
