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 “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.

■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).

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.

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.
