Effects
Effect Types
Decay
The Decay parameter is used when setting “A” type effects. Decay sets the
length of time it takes an effect to fade out. When setting up reverb effects,
Decay controls the room size and the reflectivity of the room. For larger
room sizes and greater reflectivity, set the Decay value higher. When setting
up delay effects, the Decay parameter controls how many echoes are
produced or how long the echoes last. The greater the value, the more
echoes and longer lengths of time.
The Decay value range is from 0 through 90.
High Frequency Damping
The HF Damping parameter is used when setting “A” type effects. High
Frequency energy tends to fade away first as a sound is dissipated in a room.
the HF Damping parameter adjusts the amount of damping applied to the
signal’s high frequency elements which, in turn, changes the characteristics
of the room. Rooms with smooth, hard surfaces are more reflective and
have less high frequency damping. Rooms filled with sound absorbing
materials, such as curtains or people, have more high frequency damping.
The value range for High Frequency Damping is from 0 through 127.
Feedback
The Feedback parameter is used when setting “B” type effects. The Chorus
and Flange effects have a controllable feedback loop after the delay
element. Feeding back a small amount of the signal intensifies the effect by
creating multiple cancellations or images. Higher feedback values increase
the amount of the Feedback loop.
The Feedback value range is from 0 to 127.
LFO Rate
The LFO Rate parameter is used when setting “B” type effects. Both Chorus
and Flange effects use a Low Frequency Oscillator (LFO) to animate the
effect. LFO applied to a chorus effect creates the slight changes necessary
for a realistic choral effect. Applied to a flanger effect, the LFO moves the
comb filter notches and adds animation to the sound.
The LFO Rate value range is from 0 to 127.
Delay
Flanging, chorus and echoes are all based on a delay line where the signal is
delayed by some time period and then mixed back with the unaltered
signal. This parameter specifies the how much time passes before you hear
the delayed signal. On some effects, this value cannot be changed. In this
case, the field contains a dash.
The Delay value range is from 0ms to 635ms.
