Lexicon PCM92 Category Room, Chorus Depth Concert Hall, Chorus Rate Concert Hall, Definition

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.
