Insert Effect Parameter Functions

De-esser

Useful for reducing ‘sibilant’ or ‘S’ sounds produced by a vocalist.

On/Off OFF, ON

This parameter turns the de-esser effect on/off.

Sibilant 0–100

Adjusts the sensitivity relative to the input volume, which controls how the effect is applied.

Level 0–100

Adjusts the volume.

Defretter

This simulates a fretless bass.

On/Off	OFF, ON
This parameter turns the defretter effect on/off.
Sens	0–100

This controls the input sensitivity of the Defretter. It should be adjusted for the bass guitar you have until you get the harmonic changes to sound natural.

Attack 0–100

This controls the attack of the Defretter. Increasing the value will cause the harmonics to change more slowly, thus producing a relatively attack-less sound, similar to a fretless bass.

Depth 0–100

This controls the ratio of harmonics. Increasing the value will increase the harmonic content and therefore will create a more unusual sound.

Level 0–100

Adjusts the volume of the defretter sound.

Delay

This creates a thicker sound by applying a delayed sound to the direct sound.

On/Off OFF, ON

This parameter turns the delay effect on/off.

Type

This Parameter selects the type of delay.

SINGLE:

This is a simple delay.

TAP:

The delayed sound is panned across the left and right channels. This will be effective when stereo recording.

Dly Tme SINGLE: 1–1400 ms, TAP: 1–700 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 0–120

Adjusts the volume of the delay sound.

Doubling

By adding a slightly time-delayed sound to the direct sound, this produces the impression that multiple sources are sounding together (a “doubling” effect). Best results will be achieved when stereo recording.

*This effect can be used when the MODULATION “Type” parameter is set to “DOUBLING.”

On/Off OFF, ON

This parameter turns the doubling effect on/off.

Dly Tme 0.5–50.0 ms

This parameter adjusts the delay time (i.e., the interval for which sound is delayed).

Separation -50– +50

Adjusts the diffusion. The panning of the direct sound and effect sound can be spread to left and right.

*This effect is obtained with stereo recording (using two tracks).

E.Level 0–120

This adjusts the volume of the delay sound.

Enhancer

By adding sounds which are out-of-phase with the direct sound, this effect enhances the definition of the sound, and pushes it to the forefront.

On/Off OFF, ON

This parameter turns the enhancer effect on/off.

Sens 0–100

Adjusts the manner in which the enhancer will be applied relative to the input signals.

Freq 1.0–10.0 kHz

Adjusts the frequency at which the enhancer effect will begin to be applied. The effect will be made apparent in the frequencies above the frequency set here.

Mix Level 0–100

Adjusts the amount of phase-shifted sound of the range set by “Frequency” that is to be mixed with the input.

Lo Mix Lvl 0–100

Adjusts the amount of phase-shifted sound of the lower range that is to be mixed with the input. The frequency range in which the effect is applied is fixed.

Level 0–100

Adjusts the volume of the enhanced sound.
