5.3.4 Phase
Primary parameters
A classic com
b filtering phase effect is available with basic parameter controls.
1.
Curve
– Adjusts the phase shift between the signals that create the comb
filter effect. The effect does not automatically oscillate like other phase
effects, so lever 1 can be used to manually adjust the time shift.
2. Lever not used.
3. Lever not used.
4.
Predelay
– Sets the amount of delay before processing takes effect,
selectable between 0, 20, 40 and 60 ms.
Secondary parameters (enable SET)
1.
Mix
– Determines how much of the processed signal is mixed with the dry
signal. A setting of 50% yields an even blend of wet and dry signals. 0% mix
corresponds to setting “0.4”, 25% mix to “1.0”, 50% to “2.0”, 75% to “3.0”
and 100% to “4.5".
2. Lever not used.
3.
Out Select
– Selects between the front L/R outputs and rear L/R outputs,
which have slightly different sounds on the original classic reverb unit.
4. Lever not used.
Note: If it is a stereo instance, the signal is mixed to mono before the t1 block.
(see Signal Diagrams in Chapter 8)
5.3.5 Chorus
The chorus effect adds several time-shifted duplications of the original signal,
giving a thicker texture to the sound. It is designed to be great for both chorus-
sensitive instruments like piano and strings as well as chorus-hungry instruments
like distorted guitar.
Primary parameters
1. Lever not used.
2.
Modulation
– Adjusts the modulation depth.
3.
Tap Enable
– Selects how many time-shifted voices are present, giving a
more intense effect. Settings are I, I+II, I+II+III, and I+II+III+IV.
4.
Predelay
– Sets the amount of delay before processing takes effect,
selectable between 0, 20, 40 and 60 ms.
Secondary parameters (enable SET)
1.
Mix
– Determines how much of the processed signal is mixed with the dry
signal. A setting of 50% yields an even blend of wet and dry signals. 0% mix
corresponds to setting “0.4”, 25% mix to “1.0”, 50% to “2.0”, 75% to “3.0”
and 100% to “4.5".
2-4. Levers not used.
5.3.6 Echo
This is a mono echo effect that may be easier to use than the Delay program.
It’s a unique echo effect in that Lo and Hi Mult affect the feedback as “decay
multipliers” similar to the reverb rather than applying a Lo and Hi Cut in the
feedback as typical Echo effects do.
Primary parameters
1.
Time Coarse
– Sets the delay time in 20 ms increments from 0 to 300 ms.
2.
Time Fine
– Sets the fine delay time in addition to the setting of lever 1,
adjustable between 0, 5, 10 or 15 ms.
3.
Feedback
– Adjusts the number of repeats.
4.
Predelay
– Sets the amount of delay before processing takes effect,
selectable between 0, 20, 40 and 60 ms.
Secondary parameters (enable SET)
1.
Mix
– Determines how much of the processed signal is mixed with the dry
signal. A setting of 50% yields an even blend of wet and dry signals. 0% mix
corresponds to setting “0.4”, 25% mix to “1.0”, 50% to “2.0”, 75% to “3.0”
and 100% to “4.5".
2.
Lo Mult
– Adjusts the low frequency damping of the repeats.
3.
Hi Mult
– Adjusts the high frequency damping of the repeats.
4. Lever not used.
5.3.7 Space
The space reverb has a very long decay and minimal parameter adjustments.
It can be used as a special effect for creative purposes.
Primary parameters
1-3. Levers not used.
4.
Predelay
– Sets the amount of delay before processing takes effect,
selectable between 0, 20, 40 and 60 ms.
Secondary parameters (enable SET)
1.
Mix
– Determines how much of the processed signal is mixed with the dry
signal. A setting of 50% yields an even blend of wet and dry signals. 0% mix
corresponds to setting “0.4”, 25% mix to “1.0”, 50% to “2.0”, 75% to “3.0”
and 100% to “4.5".
2-4. Levers not used.
