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

34

echo buffer.
