Insert Effect Parameter Functions

Equalizer

A 4-band equalizer.

*You can use this effect with the following algorithms when “4BAND EQ” is selected for the 4BAND EQ/WAH “Type” setting.

COSM GTR AMP	COSM BASS AMP
COSM COMP GTR	COSM COMP BSS
BASS MULTI	STEREO MULTI
On/Off	OFF, ON

This parameter turns the equalizer effect on/off.

Low Gain -20– +20 dB

This parameter sets the gain (amount of boost or cut) for the bass equalizer.

Lo-M Gin -20– +20 dB

This parameter sets the gain (amount of boost or cut) for the low- midrange equalizer.

Lo-M F 100 Hz–10.0 kHz

This parameter sets the central frequency for the low-midrange equalizer.

Lo-M Q 0.5–16

This parameter sets the range of change in gain for the frequency set by “Lo-M F.” A larger value results in a narrower range of change.

Hi-M Gin -20– +20 dB

This parameter sets the gain (amount of boost or cut) for the high- midrange equalizer.

Hi-M F 100 Hz–10.0 kHz

This parameter sets the central frequency for the high-midrange equalizer.

Hi-M Q 0.5–16

This parameter sets the range of change in gain for the frequency set by “Hi-M F.” A larger value results in a narrower range of change.

Hi Gain -20– +20 dB

This parameter sets the gain (amount of boost or cut) for the treble equalizer.

Level -20– +20 dB

This parameter adjusts the volume after the equalizer stage.

Flanger

This produces a flanging effect that gives a sort of “twisting” character to the sound.

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

On/Off OFF, ON

This parameter turns the flanger effect on/off.

Rate 0–100

Determines the rate of the flanging effect.

Depth 0–100

Determines the depth of the flanging effect.

Manual 0–100

Adjusts the center frequency at which to apply the effect.

Resonance 0–100

Determines the amount of resonance (feedback). Increasing the value will emphasize the effect, creating a more unusual sound.

Separation 0–100

Adjusts the diffusion. The diffusion increases as the value increases. This will be effective when stereo output is used.

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

Foot Volume

Specify the volume between effects.

By using an expression pedal to control the foot volume, you can smoothly change the volume of the output sound. For a detailed explanation, see “When Using an Expression Pedal” (p. 187).

On/Off OFF, ON

Switches the foot volume on/off.

Lo-Fi Box

Produces a lo-fi sound.

On/Off OFF, ON

This parameter turns the lo-fi box effect on/off.

Type

Select the mode of the lo-fi box.

RADIO:

The sound will appear to be heard from an AM radio.

*By adjusting “Tuning,” you can simulate the sounds that occur when you adjust the tuning frequency of the radio.

PLAYER:

The sound will appear to be heard from a gramophone. The noise caused by scratches and dust on the record are is simulated.

DIGITAL:

This allows you to create a “lo-fi” sound by lowering the sample rate and/or decreasing the number of bits. Realtime modify filters connected in series allow you to reshape the sound freely.

■When “RADIO” or “PLAYER” is selected

Tuning 0–100

This is a parameter for “RADIO.” It simulates the sounds that occur when you adjust the tuning frequency of an AM radio.

Wow Flt 0–100

This is a parameter for “PLAYER.” It simulates the wow and flutter which occur when the speed of the turntable is not constant.

Noise	0–100
This simulates noise.
Filter	0–100
Adjusts the filter.
D:E	100:0–0:100

This adjusts the volume balance of the direct and effect sounds.
