Operation

The effector has the same basic built-in filter as Wah. The filter frequency shift element is the

input signal level envelope, so the wah effect is applied automatically in accordance with key-

board play.

Both high-speed and low-speed response to the input signal are provided, and these cannot be

adjusted.

1.

Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.

FilterType

Either BPF (Band Pass Filter) or LPF (Low Pass Filter) can be selected as the filter type.

Using BPF outputs only narrow band signals, so the change in the tone is great.

3.

Freq

When BPF is selected, this parameter controls the mid-range equalizer center trigger fre-

quency. When LPF is selected, this parameter controls the mid-range equalizer trigger fre-

quency.

4.

Resonance

Resonance of the wah effect.

5.

Sens

Input signal sensitivity. The greater the value, the greater the change.

Operation

This effector amplifies the input signal and limits the wave height to produce distortion. In addi-

tion to electric guitar tones, this effect can also be applied to bass, electric piano, organ, reed

synth, drum, vocal, and other tones.

This effector also has a number of built-in algorithms for different characteristics, which can be

selected with the parameters.

This effector also has an internal noise gate. When an externally input signal is passed through this

effector, it may be desireable to perform a noise gate operation earlier than the externally input

noise gate. This can be accomplished by changing the settings of the distortion effector's indepen-

dent noise gate.

1.

Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.

Type

Distortion type

o Crnch (Crunch)

Light distortion

o OD (Overdrive)

Warm distortion

o Dist (Distortion)

Hard and straight distortion

o Metal

Metallic distortion with enchanced low and high ranges

o Fuzz

Fuzz sound often heard in music from the late 60's and early 70's

3.

Drive

Amplification factor. The maximum amplification factor depends on the selected Type. Noth-

ing is sounded when this parameter is 0.

4.

Tone

Tone quality. A larger tone results in a brighter tone.

5.

NG.Thresh

Threshold level of the internal noise gate. Output is muted whenever the input signal drops

below the level specified by this parameter.

6.

NG.Release

Internal noise gate gate close time when muting.

7.

Level

Output level.
