DELAY ALGORITHMS

Note:

See the parameter glossary that begins

on page 8 for delay algorithm parameter

descriptions. See pages 23 to 27 for

delay algorithm diagrams.

SIMPLE DELAYS

Simple Delays are basic delay algorithms that

feature one delay line for each input channel.

(During 5-channel operation, the center input

channel is split between the left and right

input channels.) Each delay line has a

single output, called a “voice.” Each voice has

independent delay time (up to 4 seconds),

output level, feedback control, filtering, and

panning. The feedback path includes diffusion,

as well as highpass and lowpass filters. In

addition to this basic voice architecture,

Simple Delays also feature diffusion control for

diffusors in the input and feedback paths.

Simple Delays are available in stereo, quad,

and 5-channel DSP configurations.

DUAL DELAYS

Dual Delays are similar to Simple Delays,

except Dual Delays feature two delay lines for

each input channel. Each delay line has a single

output or “voice.” Each voice has independent

delay time (up to 2 seconds), output level,

feedback control, filtering, and panning.

The feedback path includes highpass and

lowpass filters. In addition to this basic voice

architecture, Dual Delays feature parameters

that provide expanded diffusion controls.

RANDOM DELAYS

Random Delays provide no-holds-barred control

over delays. These algorithms feature one delay

line per input channel. (During 5-channel

operation, the center channel is split between

the left and right channels.) Each delay line

has three outputs, called “voices.” Each voice

has independent delay time (up to 3 seconds,

plus an additional second provided by the

randomizers described in the next paragraph),

output level, feedback control, filtering, and

panning. Random Delays have the same

diffusion controls as Dual Delays.

In addition to this basic voice architecture,

Random Delays feature two randomizers that

provide up to one second of additional delay

time for each voice. Voices can be assigned to

either randomizer, or to no randomizer at

all. See the Rand1 and Rand2 parameter

descriptions on page 9 for more information.

Random Delays are similar to Simple Delays,

but are especially useful for:

•Multitap Tape Loops

Feedback can be used to recirculate

delays. Appropriate use of highpass and

lowpass filters emulates the bandpass

effects of multi-generational tape loops

(hiss not included). Feedback diffusion

allows emulation of azimuth misalignment

– a hallmark of the sound.

•Early Reflection Modeling

Although different in scope from Lexicon

Ambience algorithms, Random Delays can

be used to place early reflections in stereo

or surround fields. The Rand1 and Rand2

parameters, which control randomization,

can be used to prevent coloration that

might otherwise occur with straight

delays.

. . . Random Delays continues on page 8

Delays & Additional 96kHz Reverbs Package

960L

Random Delays (continued from page 7)

•Doublers

A number of techniques can be used

to randomize short delays (10 to 50

milliseconds, depending on the material).

Randomization produces a variable delay

time that can be used to create a

convincing doubled voice.

•Very Strange Sounds

When the Wand1, Wand2 parameters are

set to long times, randomization can be

used to generate unpredictable delays.

Random Delays are available in stereo, quad,

and 5-channel DSP configurations.

DELAY ALGORITHM PARAMETERS

Two types of parameters are available for

delay algorithms: standard and delay voice

parameters. Standard parameters are global,

affecting the entire algorithm. Delay voice

parameters affect individual voices. Both types

are included in the glossary that begins below.

Standard Parameters (Global)

Ctr In

Adjusts the level of the center input channel

in 5-channel DSP configurations. (This

parameter has no effect in other DSP

configurations.) Unless center channel audio is

discrete, it is recommended to set the Ctr In

parameter 6dB below the InLvl parameter.

DelMST

Controls the length of all delays. Adjustments

made to the DelMST parameter will not take

effect until the Hold parameter is set to OFF.

Diffus

Controls the amount of diffusion in the input

and feedback paths. At a minimum, the

diffusor has no effect. As diffusion increases,

the signal becomes "smeared."

FbHipass

Controls the highpass filter in the feedback

path.

FbkDiff

Provides control of diffusion in the feedback

path. This parameter can be used to create the

effect of looping echoes fading into the

background, which is useful when modeling

tape loops and other effects.

FbkMST

For Simple Delays, controls the level of all

feedbacks. For Dual Delays, controls the level

of all feedbacks and crossfeeds. Adjustments

made to the FbkMST parameter will not take

effect until the Hold parameter is set to OFF.

FbRoll

Controls the lowpass filter in the feedback

path.

Fgrain

Controls grain for the diffusor in the feedback

path. See the Grain parameter description at

the top of the next page.

FsLvl

Sends the front left and right input channels to

the surround left and right input channels,

allowing up to 12 voices to exist for a stereo

signal. This is useful when only one stereo

input signal is present.

Delays & Additional 96kHz Reverbs Package Lexicon

Grain

Provides extended control of diffusion in the

input path. A low setting produces a tight

smear pattern (perhaps only discernable with

percussion). A large setting produces a more

widespread pattern.

Hold

Provides infinite hold for audio in delays. Each

delay loops at its delay length. When Hold is

set to ON, no input signal is admitted into the

delay. Voices can still be panned, and filters

and gains can still be adjusted. Output

adjustments made to the DelMST or Fbk

parameters will not take effect until the Hold

parameter is set to OFF.

For Random Delays, the Hold parameter

functions as described above, except that only

Voice 1 is recirculated. The output from all

voices is still available.

InLvl

Controls input level. Normally, this parameter

can be set to 0dB. But high levels of diffusion

or strong low-frequency content may require a

setting of -6dB or lower.

LvlMST

Controls the level of all delays.

Mix

Controls the wet-to-dry mix ratio.

Mod1, Mod2

Modify Randomizer 1 and Randomizer 2. The

setting can be a threshold or a rate, depending

on the Rand1, Rand2 parameter setting.

Rand1, Rand2

Select the randomizer type for Randomizer 1

and Randomizer 2. When set to SloRand, one

delay voice is changed at a time at the rate

specified by the Mod1, Mod2 parameter.

When set to FstRand, all delay voices are

changed at once at the rate specified by the

Mod1, Mod2 parameter. When set to Gate,

wander time is added to all delay voices

whenever input level rises above the threshold

specified by the Mod1, Mod2 parameter.

When set to –Gate, wander time is added to

all delay voices whenever input level falls

below the threshold specified by the Mod1,

Mod2 parameter.

V1Rand, V2Rand, V3Rand

Designate the randomizer that affects all Voice

1s (ones), Voice 2s (twos), and Voice 3s

(threes). Voices can be assigned to Randomizer

1, Randomizer 2, or no randomizer at all.

Wand1, Wand2

Specify the amount of delay added to voices

affected by Randomizer 1 and Randomizer 2.

When the Rand1, Rand2 parameter is set to a

gate mode, the full amount is added. When

the Rand1, Rand2 parameter is set to a rand

mode, the wander amount ranges between 0

and the full randomizer amount.

Delay Voice Parameters

Note:

Each delay voice has a name: L1 indi-

cates Left 1, R2 indicates Right 2, and so

on.

Delay Time

Adjusts delay length. See the Fine Adjusting

Parameter Settings section that begins on

page 12 for instructions to fine adjust the

Delay Time setting. Be aware of the DelMST

parameter setting when making adjustments

to the Delay Time parameter.

Fbk

Adjusts voice feedback from positive unity gain

to negative unity gain, although full-scale will

probably cause accumulation or saturation,

which creates distortion. A non-zero setting

will feed the delay back into the input. Voices

can feed back even when the Gain parameter

is set to off. Be aware of the FbkMST parameter

setting when adjusting the Fbk parameter.

Adjustments made to the Fbk parameter will

not take effect until the Hold parameter is set

to OFF.

Hint:

To set the Fbk parameter to off, press

and hold the FINE ADJ button on the

LARC2 and lightly touch the appropriate

fader.

Filt

Controls the filter of each voice. In the center

position, the filter is flat. Below the center

position, the filter becomes lowpass, removing

more high-frequency content as the fader is

lowered. Above the center position, the filter

becomes highpass, removing more low-

frequency content as the filter is raised. This

parameter only affects voice output, not

feedback.

Hint:

To set the Filt parameter to flat, press

and hold the FINE ADJ button on the

LARC2 and lightly touch the appropriate

fader.

Gain

Adjusts voice gain from positive unity gain to

negative unity gain. Be aware of the LvlMST

parameter setting when making adjustments

to the Gain parameter.

Hint:

To set the Gain parameter to off, press

and hold the FINE ADJ button on the

LARC2 and lightly touch the appropriate

fader.

Pan

Adjusts voice pan. Press the JOYSTICK button

on the LARC2 to engage the panner for the

current voice.

Xfd

Adjusts the crossfeed control from positive

unity gain to negative unity gain, injecting the

delay signal into the opposite delay line. The

Xfd parameter can be used to create ping-

ponging effects or density buildup. Voices can

be crossfed even when the Gain parameter is

set to off. Be aware of the FbkMST parameter

setting when adjusting the Xfd parameter.

For Surround Delays, the Xfd parameter

functions as described above, except for the

target. The crossfed data is set to the opposite

corner (i.e. front left is sent to surround right

and surround left is sent to front right.

Hint:

To set the Xfd parameter to off, press

and hold the FINE ADJ button on the

LARC2 and lightly touch the appropriate

fader.
