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 keyboard 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.SensInput 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 addition 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 independent 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 MetalMetallic distortion with enchanced low and high ranges o FuzzFuzz sound often heard in music from the late 60's and early 70's3.Drive

Amplification factor. The maximum amplification factor depends on the selected Type. Noth- ing is sounded when this parameter is 0.

4.ToneTone 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.ReleaseInternal noise gate gate close time when muting.7.Level Output level.
