Loop Effect Parameter Functions
Parameter List
CHORUS/DELAY/DBLN (Doubling)
This selects the chorus, delay, or doubling effect.
FX Type
This sets the type of the effect.
CHORUS:
A sound with a subtly shifted pitch is added to the direct sound,
making the final output sound thicker and broader.
DELAY:
This creates a thicker sound by applying a delayed sound to the
direct sound.
DBLN:
By adding a slightly time-delayed sound to the direct sound, this
produces the impression that multiple sources are sounding together
(a “doubling” effect). The delayed sound will be output from the
side opposite to which the playback track has been panned.
■ When “CHORUS” is selected
Rate
0–100
Adjusts the rate of the Chorus effect.
Depth 0 –100
Adjusts the depth of the Chorus effect.
Pre Dly 0.5–50.0 ms
Adjusts the time needed for the effect sound to be output after the
direct sound has been output.
E.Level 0–100
Adjusts the volume of the effect sound.
■ When “DELAY” is selected
Dly Tme
10–1000 ms
This parameter adjusts the delay time (i.e., the interval for which
sound is delayed).
Feedback 0–100
This parameter adjusts the amount of feedback. Changing the
amount of feedback causes the number of time the delayed sound is
repeated to change as well.
E.Level 0–100
This adjusts the volume of the delay sound.
Rev Send 0–100
Adjust the volume of the reverb that is applied to the delayed sound.
■ When “DBLN” is selected
Dly Tme
0.5–50.0 ms
This parameter adjusts the delay time (i.e., the interval for which
sound is delayed).
E.Level 0–100
This adjusts the volume of the delay sound.
REVERB
Reverberation (or reverb) is the effect caused by sound waves
decaying in an acoustic space, or a digital simulation thereof. This
decay occurs because sound waves bounce off many walls, ceilings,
objects, etc. in a very complex way. These reflections, coupled with
absorption by various objects, dissipate the acoustic energy over a
certain period of time (called the decay time). The ear perceives this
phenomenon as a continuous wash of sound.
Type
This selects the Reverb Type.
ROOM:
Simulates the reverberation in a small room.
HALL:
Simulates the reverberation in a concert hall.
Rev Time 0.1–10.0
This parameter adjusts the duration (time) of the reverb.
Tone -12– +12
Adjusts the tone.
E.Level 0–100
This adjusts the volume of the reverb sound.
